Background Alirocumab reduces low-density lipoprotein cholesterol (LDL-C) levels by up to 61%. The ODYSSEY Open-Label Extension study investigated the effect of alirocumab in patients with heterozygous familial hypercholesterolaemia (HeFH) over 144 weeks. Methods Eligible patients with HeFH had completed an earlier double-blind, randomised, placebo-controlled parent study. Patients were initiated on 75 mg alirocumab Q2W subcutaneous (SC) unless baseline LDL-C was > 8.9 mmol/l, in which case they received 150 mg alirocumab Q2W. Dose titration to 150 mg Q2W was at the investigator's discretion. Results The study enrolled 167 patients and the parent study mean (± SD) baseline LDL-C level was 3.65 ± 1.9 mmol/l. Mean LDL-C level was reduced by 48.7% at week 144; mean on-treatment LDL-C was 2.30 ± 1.24 mmol/l. Eight patients reported injection-site reactions, with one treatment discontinuation. Treatment emergent anti-drug antibodies were identified in five patients but these did not affect the efficacy. Conclusions Alirocumab effectively and safely reduced LDL-C in these patients.

In principle, mandatory vaccination in employment could be justified in certain circumstances. These include: (1) the availability of safe and effective vaccination; (2) if alternative, less coercive strategies did not work; and, (3) the costs to the individual were proportionate. However, in COVID-19, the long term safety of vaccines is yet to be established. Vaccines should be made available by employers, and voluntary vaccination encouraged.

Backgound/Introduction In phase I KAT301 trial, adenovirus-mediated intramyocardial vascular endothelial growth factor-DΔNΔC (VEGF-D) gene therapy (GT) resulted in a significant improvement in myocardial perfusion reserve and relieved angina at 1-year follow-up without major safety concerns. Purpose Our objective was to investigate the long-term safety and efficacy of AdVEGF-D GT. A total of 30 patients (24 VEGF-D and 6 randomized and blinded controls) participated in KAT301 trial. Methods The mean follow-up time was 8.2 years (range 6.3–10.4 years). Patients were interviewed for the current severity of symptoms (Canadian Cardiovascular Society class, CCS) and perceived benefit from GT. Medical records were reviewed to assess the incidence of major cardiovascular adverse events (MACEs) and other predefined endpoints including cancer. Results MACE occurred in 15 patients in VEGF-D group and in five patients in control group (21.5 vs. 24.9 per 100 patient-years; hazard ratio 0.90; 95% confidence interval 0.09–9.32; P=0.95). Mortality and comorbidity were similar between the groups. Angina symptoms (CCS) were less severe compared to baseline in VEGF-D group (1.9 vs. 2.9; P=0.006) but not in control group (2.2 vs. 2.6; P=0.414). Conclusion(s) Our study indicates that intramyocardial AdVEGF-D GT is safe in the long-term. In addition, the relief of symptoms remained significant during the follow-up.

Introduction Adeno-associated virus (AAV)-based gene therapy for haemophilia presents a challenge to the existing structure of haemophilia centres and requires a rethink of current collaboration and information exchange with the aim of ensuring a system that is fit-for-purpose for advanced therapies to maximise benefits and minimise risks. In Europe, a certification process based on the number of patients and facilities is offered to the haemophilia centres by European Haemophilia Network (EUHANET). Aim and methods This joint European Association for Haemophilia and Allied Disorders (EAHAD) and European Haemophilia Consortium (EHC) publication describes criteria for centres participating in gene therapy care that require a reassessment of the infrastructure of comprehensive care and provides an outlook on how these criteria can be implemented in the future work of haemophilia centres. Results The core definition of a haemophilia treatment centre remains, but additional roles could be implemented. A modifiable ‘hub-and-spoke’ model addresses all aspects associated with gene therapy, including preparation and administration of the gene therapy product, determination of coagulation and immunological parameters, joint score and function, and liver health. This will also include the strategy on how to follow-up patients for a long-term safety and efficacy surveillance. Conclusion We propose a modifiable, networked ‘hub and spoke’ model with a long term safety and efficacy surveillance system. This approach will be progressively developed with the goal of making haemophilia centres better qualified to deliver gene therapy and to make gene therapy accessible to all persons with haemophilia, irrespective of their country or centre of origin.

Cladribine is currently registered as a 10-milligram tablet formulation with a fixed cumulative dosage of 3.5 mg/kg over 2 years. It is important to investigate if an increased dosage may lead to further clinical stability with preserved safety. This study used an off-label subcutaneous (s.c.) formulation of cladribine and compared outcomes (Expanded Disability Status Scale (EDSS) scores and disease progression) between 52 relapsing multiple sclerosis (RMS) patients receiving different s.c. dosing regimens with up to 20 years of follow-up. The study group received induction therapy with s.c. cladribine (1.8 mg/kg cumulative dose, consistent with 3.5 mg/kg of cladribine tablets). Patients were subsequently offered maintenance therapy (repeated courses of 0.3 mg/kg s.c. cladribine during 5–20-year follow-up). Forty-one patients received an increased cumulative dose (higher than the induction dose of 1.8 mg/kg), 11 received the standard induction dose. Risk of progression on the EDSS correlated with lower cumulative dose (p &lt, 0.05) and more advanced disability at treatment initiation (p &lt, 0.05) as assessed by EDSS change between year 1 and years 5 and 10 as the last follow-up. Maintenance treatment was safe and well-tolerated, based on limited source data. Subcutaneous cladribine with increased cumulative maintenance dosage was associated with disease stability and favorable safety over a prolonged period of follow-up (up to 20 years) in RMS patients.

Purpose The purpose of this study was to systematically search for long-term complications, including Nephrogenic Systemic Fibrosis (NSF), in patients who were previously administered the gadolinium-based contrast agent Gadofosveset at our institute. Materials and methods All patients who were administered Gadofosveset at our institute between 2006 and 2009 were identified in our Radiological Information System (RIS). Clinical data such as cause of death during follow-up, and dermatological or nephrological diseases were systematically searched for in electronic patient records (EPR). Results During 2006–2009, Gadofosveset was administered a total of 67 times to 62 patients. One patient was unavailable for follow-up. The remaining 61 patients were followed up for up to 14 (median 12) years based on RIS and EPR data. There were 13 deaths among the 61 patients, all assessed as unrelated to Gadofosveset administration. No dermatological or renal disease suggestive of NSF, or potentially related to Gadofosveset administration, was found. At the time of examination, six patients were diagnosed with various stages of renal insufficiency, three of whom were on hemodialysis. Another three patients were diagnosed with renal insufficiency during the follow-up period, but none of these diagnoses were suspected to be related to the administration of Gadofosveset. Conclusions Based on the results of this retrospective safety analysis of up to 14 years following 1–2 exposures, we conclude that Gadofosveset in clinical practice is safe in the long-term.

Purpose: To examine patterns of standard (trabeculectomy or glaucoma drainage devices, GDDs) vs novel (minimally invasive glaucoma surgery, MIGS) surgical techniques in the US.Methods: We used the American Academy of Ophthalmology (AAO) IRIS® Registry (Intelligent Research in Sight) queried between 2013 and 2018 (inclusive) to calculate the cumulative proportion of stand-alone, concurrent (same day) or sequential (subsequent day) glaucoma surgical techniques performed in each glaucoma diagnosis type. Secondary analyses of adjusted proportions of concurrent and sequential surgeries stratified by glaucoma diagnosis were also performed.Results: Of 203,146 eyes receiving glaucoma surgeries, open angle glaucoma (OAG) was most likely to undergo all types of intervention. The iStent was the most commonly performed MIGS, primarily for those with normal tension glaucoma (NTG) or OAG (p < .001). Conversely, GDD was the most commonly performed procedure in secondary glaucoma or other (specified) glaucoma (p < .001). ECP and iStent were the most common concurrent procedures performed; most often for OAG and NTG (p < .001). After an initial standard surgery, most eyes underwent recurrent standard interventions (90.3%). ECP was the most common MIGS performed after an initial standard surgery; particularly in primary angle-closure (PACG) and secondary glaucoma eyes (p < .001).Conclusion: Glaucoma type may influence the choice of glaucoma procedures and the decision to perform concurrent as well sequential surgical procedures. Given the poorly understood long term safety and effectiveness of MIGS, and with substantially increasing use of MIGS procedures in recent years, future studies comparing their safety and effectiveness vs standard interventions, for a variety of glaucoma types, is needed.

The primary objective of this trial (SP1042; NCT02582866) was to assess long‐term safety and tolerability of lacosamide monotherapy (200‐600 mg/day) in adults with focal (partial‐onset) seizures or generalized tonic‐clonic seizures (without clear focal origin). This Phase III, long‐term, open‐label, multicenter, follow‐up trial enrolled patients with epilepsy who were taking lacosamide in, and completed, the previous double‐blind trial (SP0994; NCT01465997). Primary safety outcomes were treatment‐emergent adverse events (TEAEs), discontinuations due to TEAEs, and serious TEAEs. One hundred and six patients were enrolled and received lacosamide: 84 (79.2%) completed the trial and 22 (20.8%) discontinued. The median duration of exposure was 854.0 days, with a median modal dose of 200 mg/day. Ninety‐six (90.6%), 64 (60.4%), and 44 (41.5%) patients had ≥12, ≥24, and ≥36 months of lacosamide exposure, respectively. At least one TEAE was reported by 61 (57.5%) patients. The most common (≥4%) TEAEs were headache (10 [9.4%]), nasopharyngitis (eight [7.5%]), and back pain (five [4.7%]). One (0.9%) patient discontinued due to a TEAE (sudden unexpected death in epilepsy; not considered drug‐related), 14 (13.2%) patients reported serious TEAEs, and seven (6.6%) patients reported TEAEs that were considered drug‐related. Overall, long‐term lacosamide monotherapy was generally well tolerated up to 600 mg/day, with no new safety signals identified.

Hereditary Angioedema (HAE) is a potentially life-threatening condition. With episodic, unpredictable swelling, HAE negatively affect the quality of life for those affected individuals. To reduce the morbidity and mortality of HAE are the primary goal for the disease management. In addition to have access to therapeutic drugs for their acute HAE attacks, many patients require long term prophylaxis (LTP) to reduce their attack frequency and severity. Preventing HAE attack by regular administration of medicine has become an important part of HAE disease management. Over the past few years, growing number of therapeutic options for the HAE LTP have made it possible for physicians to choose the most appropriate and effective treatment for individual patients. C1 INH concentrate and plasma kallikrein inhibitors (IV or SC) have largely replaced the oder modality of treatment consisting different androgen derivatives or antifibrinolytics. Additional options, such as oral kallikrein inhibitor, antisense RNA/plasma kallikrein, anti-Factor 12a, bradykinin receptor blocker or future gene therapy are under clinical investigation. The significant cost and the uncertainty of its long term safety may be the primary limiting factors for its clinical application. The limited data for young children and pregnant women pose additional challenge for physicians to assess the risk and benefit when considering LTP treatment.

INI has emerged as a potential treatment for T2DM-related functional decline and is safe in adults without T2DM. However, INI safety in T2DM-IDDM is unknown. We aimed to demonstrate safety of long-term INI use in T2DM-IDDM MemAID participants. We screened 86 participants with T2DM-IDDM, 14 were randomized (9 INI/5 Placebo), 9 started treatment (5 INI [60±14 years, 2 Female]; 4 Placebo [68±2 years, 1 Female]). Of those, 2-INI and 3-Placebo participants completed 24 weeks of treatment and 24 weeks of follow-up. Participants underwent one week of continuous glucose monitoring (CGM)(Medtronic IPro2) at baseline and after INI (Novolin® R ) or placebo initiation. HbA1c, fasting plasma and capillary glucose, and insulin were measured throughout the study. Insulin levels were unchanged across the study. In 2 INI-treated participants, HbA1c, fasting plasma and capillary glucose declined from baseline, but the average values were similar during treatment and follow up, and comparable to 3 placebo-treated participants. Both INI-treated participants had adjustments of IDDM regimens. Capillary glucose did not decline 2 hours after INI administration, and there were no interactions between INI and subcutaneous insulin. There were no INI-related serious adverse events. Of 13 hypoglycemia (HG) episodes across the study, 2 asymptomatic level-1 HG (15.4%) occurred in INI group and 7 (53.8%) in placebo group. There were 2 asymptomatic level-2 HG (15.4%) in both INI and placebo groups. INI therapy was not associated with serious adverse events or HG in older participants with T2DM-IDDM. This study may pave the way towards future larger studies evaluating the safety of concomitant administration of INI and subcutaneous insulin (NCT02415556). Disclosure L. Aponte becerra: None. B.

Biosimilar anti-tumor necrosis factor (TNF)-alpha drugs are widely used in the treatment of psoriasis, but only few studies reported the long-term experience of the various biosimilar agents in the real world practice. A monocentric retrospective observational study was performed to assess the long-term efficacy, tolerability, and safety of biosimilars adalimumab (bADA), biosimilar etanercept (bETN), and biosimilar infliximab (bIFX) in psoriasis patients. A total of 73 patients (19 patients treated with bADA, 37 with bETN and 17 with bIFX) were enrolled and observed up to 48 months of follow-up. Regarding the efficacy, across all biosimilar treatments combined, the mean PASI score was ≤2 (1.2) after 12 months of treatments. Notably, the mean PASI score remained relatively stable during all 48 months of follow-up. With regard to tolerability and safety in the present study, 34 (28%) patients experienced adverse events during all biosimilar therapy, and three (4.3%) discontinued treatment. No severe adverse events, death, or malignancy cases were recorded during the study period. Our results support that biosimilar anti-TNF-alpha drugs are effective and well tolerated drugs for the long-term treatment of psoriasis.

Growth hormone treatment was introduced in the 1950s to address growth disturbances and metabolic abnormalities. Hundreds of thousands of children have been treated, with gradual expansion of treatment indications. From initially being offered only to patients with severe growth hormone deficiency, today many children are treated for conditions in which the associated short stature is not primarily thought to be due to deficient endogenous growth hormone secretion. This review discusses the history, physiology and safety of growth hormone treatment, with focus on the long-term risks of mortality, cardiovascular morbidity and cancer. Conclusion: Continuous follow-up is needed to increase our knowledge of the long-term treatment safety.

Pasireotide long acting (LAR) can be effective in normalizing insulin-like growth factor (IGF)-1 level in acromegaly patients inadequately controlled by octreotide or lanreotide.Determine the long-term efficacy and safety of pasireotide, including time to biochemical control and time to best response, and risk for diabetes mellitus.A retrospective multicenter study investigating the efficacy and safety of pasireotide LAR treatment in patients with active acromegaly treated for12 months.The study included 19 patients (10 men; mean age ± SD, 48.0 ± 12.9 years) treated with pasireotide for a mean of 50 ± 36 months. During the follow-up, 4 patients discontinued pasireotide treatment. Pasireotide LAR produced a tolerable and long-term significant biochemical response in 15 of 19 patients (79.0%). Mean time to IGF-1 normalization from pasireotide LAR initiation was 13.6 ± 16.9 months with early biochemical normalization (12 months) evident in 11 (64.7%) patients and delayed IGF-1 normalization in 6 (35.2%) patients. Nadir IGF-1 values were recorded within the first 12 months in 6 patients (35.3%), while in 11 patients (64.7%) lowest values were reported after12 months of treatment, including 4 of 11 patients with early IGF-1 normalization. New-onset diabetes was documented in 5 of 7 patients with pre-diabetes and in 1 of 5 patients with normal glucose homeostasis at baseline. Among patients with pre-diabetes or diabetes mellitus prior to initiating pasireotide, mean HbA1c increase was 0.56 ± 1.0%.The results support the long-term efficacy and safety of pasireotide LAR for acromegaly and support the potential delayed effect of treatment on IGF-1 normalization.

Background and Objectives: Ethanol retention therapy (ERT) under EUS guidance or a percutaneous approach is a safe treatment for large symptomatic hepatic cysts. However, reports on the long-term outcomes after ERT are very rare. Therefore, we aimed to evaluate the long-term outcomes of ERT in symptomatic large hepatic cysts. Materials and Methods: A total of 47 consecutive patients with large symptomatic hepatic cysts treated at the Asan Medical Center from April 2009 to October 2017 were analyzed. Thirty patients with right hepatic cysts were treated with ERT through a percutaneous approach, and 14 patients with left hepatic cysts were treated with ERT under EUS guidance. Three patients were treated with ERT using both methods. Results: Of the 47 patients, 43 (91%) showed complete regression and four (9%) showed partial regression on abdominal computed tomography. Recurrence of the cysts was not observed during the follow-up surveillance of a median of 66 months. Conclusions: Percutaneous catheter drainage-guided ERT and EUS-guided ERT, based on their favorable long-term outcomes, may be considered as first-line treatments in patients with large symptomatic hepatic cysts.

Rationale & Objective Epoetin alfa-epbx is a biosimilar to the reference product, epoetin alfa. We compare the safety of epoetin alfa-epbx versus epoetin alfa based on a pooled analysis of findings from 2 randomized, double-blind, comparative clinical studies, and report new data for the long-term safety of epoetin alfa-epbx. Study Design Pooled analyses of previously conducted studies. Setting & Participants Hemodialysis patients with anemia. Interventions Data from patients who received 1 or more subcutaneous or intravenous doses of study drug were integrated across route of administration in combined randomized groups (epoetin alfa-epbx, n = 423; epoetin alfa, n = 426). Data from patients who received 1 or more doses of epoetin alfa-epbx in either open-label extension trial were integrated across route of administration in a combined long-term safety studies group (n = 576). Outcomes Adverse events (AEs), immunogenicity, and other outcomes were assessed. Results Incidences of treatment-emergent AEs, serious AEs, and discontinuation of study drug treatment because of treatment-emergent AEs were similar between combined randomized epoetin alfa-epbx and epoetin alfa, which had mean treatment durations of 18.1 and 17.7 weeks, respectively. Incidences of treatment-emergent AEs, serious AEs, and discontinuation of study drug treatment because of treatment-emergent AEs were 86.5%, 39.4%, and 6.6%, respectively, for the combined long-term safety studies group, which had a mean treatment duration of 40.0 weeks. In total, 12 patients across the combined randomized groups (epoetin alfa-epbx, n = 5; epoetin alfa, n = 7) and 9 patients in the combined long-term safety studies group tested anti-recombinant human erythropoietin antibody positive in 1 or more visits during study conduct. No patient in any group developed neutralizing antibodies or pure red blood cell aplasia. Limitations Epoetin alfa comparator not included in the long-term safety studies, greater cumulative exposure to study drug for epoetin alfa-epbx, shorter follow-up in the randomized studies, and potential for selection bias among patients in the open-label long-term safety studies. Conclusions This analysis reinforces previous conclusions of similar safety profiles between epoetin alfa-epbx and epoetin alfa. Furthermore, epoetin alfa-epbx had no unexpected safety signals during long-term treatment. Funding This study was funded by Hospira Inc, which was acquired by Pfizer Inc in September 2015.

Purpose Clinical trials have demonstrated the favorable efficacy/safety profile of pasireotide in patients with Cushing’s disease (CD). We report interim long-term results of an ongoing real-world evidence study of subcutaneous pasireotide in patients with CD. Methods Adults with CD receiving pasireotide, initiated before (prior-use) or at study entry (new-use), were monitored for ≤ 3 years during a multicenter observational study (http://clinicaltrials.gov identifier NCT02310269). Primary objective was to assess long-term safety of pasireotide alone or with other CD therapies. Results At the time of this interim analysis, 127 patients had received pasireotide (new-use, n = 31; prior-use, n = 96). Eight patients had completed the 3-year observation period, 53 were ongoing, and 66 had discontinued. Among 31 new-use and 92 prior-use patients with ≥ 1 safety assessment, respectively: 24 (77%) and 37 (40%) had drug-related adverse events (AEs); 7 (23%) and 10 (11%) had serious drug-related AEs. Most common drug-related AEs were nausea (14%), hyperglycemia (11%) and diarrhea (11%); these were more frequently reported in new users and mostly of mild-to-moderate severity. 14 (45%) new-use and 15 (16%) prior-use patients experienced hyperglycemia-related AEs. Mean urinary free cortisol (mUFC) was within normal range at baseline and months 1, 12 and 24, respectively, in: 1/16 (6%), 9/18 (50%), 1/3 (33%) and 0/0 new users; 28/43 (65%), 15/27 (56%), 27/33 (82%) and 12/19 (63%) prior users. Conclusions Pasireotide is well tolerated and provides sustained reductions in mUFC during real-world treatment of CD. The lower rate of hyperglycemia-related AEs in prior users suggests that hyperglycemia tends not to deteriorate if effectively managed soon after onset. Clinical Trial Registration Number: NCT02310269.

Objectives To address the need for long-term lasmiditan data, the GLADIATOR study evaluated the safety (primary) and efficacy (secondary) of lasmiditan for the intermittent, acute treatment of migraine attacks for up to 1 year. Methods In this prospective, randomized, open-label, Phase 3 study, patients who had completed either of two single-attack studies were offered the opportunity to be randomized 1:1 to lasmiditan 100 mg or 200 mg. Patients were asked to use lasmiditan as the first treatment for each new migraine attack of at least moderate severity. Assessments occurred at baseline and at prespecified time increments up to 48 hours after each dose of study drug using an electronic diary, and safety was assessed throughout the study. Migraine Disability Assessment (MIDAS) was assessed at each visit. Results As of the cut-off date for this interim analysis (6 March 2018), 1978 patients had received ≥ 1 lasmiditan dose and treated 19,058 migraine attacks. Overall, treatment-emergent adverse events (TEAEs) were similar to those in the single-attack studies and included dizziness (18.6%), somnolence (8.5%), and paresthesia (6.8%). The frequency of TEAEs generally decreased with subsequent attacks. No treatment-related serious adverse events and no cardiovascular TEAEs potentially due to vasoconstriction were observed. For both lasmiditan doses, efficacy measures were generally consistent over study quarters and treated attacks. Overall, across all treated attacks at 2 hours post-dose, pain freedom was observed in 26.9% of the attacks treated with lasmiditan 100 mg and 32.4% of the attacks treated with lasmiditan 200 mg. MIDAS total scores decreased over time. Conclusions The interim results of this long-term study showed intermittent lasmiditan (100 mg and 200 mg) to be generally well tolerated and efficacious for the acute treatment of migraine over a 1-year period. Trial registration number: NCT02565186; https://clinicaltrials.gov/ct2/show/NCT02565186

The selection criteria, safety, and efficacy of bariatric surgery are well established in adults but are less well defined for severely obese adolescents. The number of severely obese adolescents who could benefit from weight loss surgery is increasing, although referral rates have plateaued. Surgical options for these adolescents are controversial and raise several questions. Recent studies, including the prospective Teen-Longitudinal Assessment of Bariatric Surgery Study and the Adolescent Morbid Obesity Surgery Study, help answer these questions. Early bariatric surgical intervention improves body mass index but, more importantly, improves cardiovascular and metabolic co-morbidities of severe obesity. A review of the medical, psychosocial, and economic risks and benefits of bariatric surgery in severely obese adolescents is a step toward improving the management of a challenging and increasing population. We describe the current knowledge of eligibility criteria, preoperative evaluation, surgical options, outcomes, and referral barriers of adolescents for bariatric surgery.

STUDY QUESTION Which clinical and ethical aspects of preimplantation genetic testing for monogenic disorders or structural rearrangements (PGT-M, PGT-SR) should be considered when accepting requests and counselling couples for PGT when applied for more than one condition (combination-PGT; cPGT-M/SR)? SUMMARY ANSWER cPGT is a feasible extension of the practice of PGT-M/SR that may require adapting the criteria many countries have in place with regard to indications-setting for PGT-M/SR, while leading to complex choices that require timely counselling and information. WHAT IS KNOWN ALREADY Although PGT-M/SR is usually performed to prevent transmission of one disorder, requests for PGT-M/SR for more than one condition (cPGT-M/SR) are becoming less exceptional. However, knowledge about implications for a responsible application of such treatments is lacking. STUDY DESIGN, SIZE, DURATION Retrospective review of all (40) PGT-M/SR applications concerning more than one genetic condition over the period 1995-2018 in the files of the Dutch national PGT centre. This comprises all relevant national data since the start of PGT in the Netherlands. PARTICIPANTS/MATERIALS, SETTING AND METHODS Data regarding cPGT-M/SR cases were collected by means of reviewing medical files of couples applying for cPGT-M/SR. Ethical challenges arising with cPGT-M/SR were explored against the background of PGT-M/SR regulations in several European countries, as well as of relevant ESHRE-guidance regarding both indications-setting and transfer-decisions. MAIN RESULTS AND THE ROLE OF CHANCE We report 40 couples applying for cPGT-M/SR of which 16 couples started their IVF treatment. Together they underwent 39 IVF cycles leading to the birth of five healthy children. Of the couples applying for cPGT, 45% differentiated between a primary and secondary condition in terms of perceived severity. In the light of an altered balance of benefits and drawbacks, we argue the 'high risk of a serious condition' standard that many countries uphold as governing indications-setting, should be lowered for secondary conditions in couples who already have an indication for PGT-M/SR. As a consequence of cPGT, professionals will more often be confronted with requests for transferring embryos known to be affected with a condition that they were tested for. In line with ESHRE guidance, such transfers may well be acceptable, on the condition of avoiding a high risk of a child with a seriously diminished quality of life. LIMITATIONS, REASONS FOR CAUTION We are the first to give an overview of cPGT-M/SR treatments. Retrospective analysis was performed using national data, possibly not reflecting current trends worldwide. WIDER IMPLICATIONS OF THE FINDINGS Our observations have led to recommendations for cPGT-M/SR that may add to centre policy making and to the formulation of professional guidelines. Given that the introduction of generic methods for genomic analysis in PGT will regularly yield incidental findings leading to transfer requests with these same challenges, the importance of our discussion exceeds the present discussion of cPGT.

Homozygous familial hypercholesterolemia (HoFH) is a rare and life-threatening lipid disorder characterized by extremely elevated low-density lipoprotein-cholesterol (LDL-C) concentrations and premature atherosclerotic cardiovascular disease (CVD). Conventional lipid-lowering agents remain insufficient in managing this disease, which emphasize the unmet medical need for potential therapies capable of lowering LDL-C and decreasing CVD risk in this patient population.Novel LDL receptor (LDLR) independent drugs have been recently approved or are in development for the treatment of HoFH, including lomitapide (Juxtapid®). This oral microsomal triglyceride transfer protein (MTP) inhibitor was approved in 2012 in several countries as an adjunct to a low-fat diet and other lipid-lowering drugs with or without LDL apheresis to treat patients with HoFH. This review summarizes key safety and efficacy data of lomitapide from clinical trials and 'real-life' experience.While lomitapide is an interesting therapy for treating HoFH, long-term safety, as well as cardiovascular outcome data, are yet to be provided. Precision medicine has recently contributed to the development of several agents designed to address the unmet medical need of HoFH. However, combining safety, efficacy, accessibility, and affordability in a single therapy constitutes very challenging individual and societal paradigms in HoFH treatment.

To report long-term safety and efficacy of combined percutaneous LAA and PFO/ASD closure.A retrospective study of 370 consecutive patients undergoing LAAC procedures using the Watchman (WM) device. Data were compared between 330 cases only with LAAC procedure (Group I) and 25/5 (PFO/ASD) cases with sequential procedures of LAAC and PFO/ASD closure (Group II).Compared to Group I, Group II had more males (86.7% vs. 65.8%, p0.05) and a higher rate of stroke (33.3% vs. 10.6%, p0.01), but there were no statistical differences in the remaining patient characteristics. During the follow-up period, there were no significant differences between the two groups in embolism events (6.1% vs. 0%, p = 0.39), device related thrombus (5.8% vs 3.3%, p = 1.0), major bleeding (9.4% vs. 6.7%, p = 1.0) and cardiac death (3.6% vs. 0%, p = 0.61). The observed rate of all thromboembolic events by Kaplan-Meier analysis was decreased by 39.9% and 100% and the observed annual rate of bleeding was reduced by 32.9% and 57.6% in Group I and Group II, respectively.LAAC combined with PFO/ASD closure might be an ideal choice to prevent stroke and other thrombotic complications in patients with both NVAF and PFO/ASD.

Effective delivery of inhaled drugs in chronic obstructive pulmonary disease (COPD) depends on patients' ability to correctly use an inhalation device. Nebulized delivery may be appropriate for COPD patients who cannot coordinate breath with inhalation or generate adequate inhalational force. Until recently, long-acting muscarinic antagonists (LAMAs), used for maintenance treatment of COPD, were available for delivery only via handheld inhalers. Lonhala™ Magnair™ (glycopyrrolate inhalation solution) is a LAMA delivered via the eFlowGOLDEN-5, a phase 3, randomized, open-label trial, evaluated the safety and efficacy of glycopyrrolate/eFlow CS 50 μg twice daily versus tiotropium 18 μg once daily (administered via HandiHaler™) in patients with moderate-to-very severe COPD. Only patients in the glycopyrrolate/eFlow CS group completed a study-specific device use questionnaire, evaluating patients' perceptions about ease of use, confidence in drug delivery, and overall device satisfaction at week 48 or end of study. Responses were summarized by counts and percentages.Of 620 patients who received glycopyrrolate/eFlow CS, 454 completed the questionnaire (mean age [standard deviation, SD] 63.3 [8.5] years; mean BMI [SD] 28.45 [6.208] kg/mHigh levels of satisfaction, confidence, and ease of use were reported with the eFlow CS nebulizer in this study. These findings support the use of the eFlow CS for maintenance treatment of COPD with glycopyrrolate inhalation solution.

BACKGROUND Cardiac implantable electronic devices (CIEDs) usually require the use of transvenous leads. A long-term complication of this can be venous system occlusion. This can preclude insertion of new transvenous leads, which is usually required to upgrade a device or supplant a defective lead; these patients require a new CIED system to be implanted on the contralateral side. Removal of the pre-existing device and/or leads carries substantial risks, including procedural complications and infection. An alternative is to leave the old device in-situ ("abandoned") with appropriate programming to minimize interaction. However, there is limited long term information about the safety and potential interaction between devices. METHODS AND RESULTS We identified 12045 patients who underwent CIED implant and had a CXR post-procedure at the Ottawa Heart Institute between December 1998 and September 2020. We used an artificial intelligence-based algorithm to identify all patients who had radiographic evidence of more than one CIED system. Our study cohort consisted of 17 patients. The average age was 66.7 ± 14.6 years; 3 (18%) were female. The average PADIT score was 8.2 ± 1.6, corresponding to a >3% annual risk of hospitalization for CIED infection with intervention on the pre-existing device pocket. The average time between the abandoned and new device implant was 4.9 ± 3.3 years. The abandoned device was a pacemaker in 13 (77%), and a defibrillator in 4 (24%). The new device was a pacemaker in 2 (12%) and defibrillator in 15 (88%). The most common indication for contralateral placement was occluded veins, in 14 (82%) patients. Follow up was 3.7 ± 3.5 years; over this time, 6 patients had end-of-life reached on the abandoned device; device output was set to minimal voltage and pulse width. Three were Medtronic pacemakers that self-reverted to VVI 65. This caused interference with a CRT in one patient, necessitating explant of the abandoned device. In the second patient, the new device was programmed at VOO 80bpm to overcome the abandoned device. In the last patient, the abandoned device did not capture the myocardium at minimal output settings. In the remainder of the patients, no device interference was found; one additional patient had abandoned CIED removed for discomfort. CONCLUSION We found that abandoning devices is feasible and safe in the long-term, and can be used to avoid the risks incurred by device explant. Careful attention should be paid to end-of-life behaviour of certain abandoned devices and necessary programming to prevent interaction.

Purpose: The purpose of this case series is to evaluate the long-term visual outcomes of patients undergoing epiretinal membrane (ERM) removal combined with internal limiting membrane (ILM) peeling via sutureless vitrectomy. Methods: A retrospective review was conducted of 45 patients (45 eyes) with ERMs treated with 25-gauge pars plana vitrectomy (PPV) from 2010 to 2011. Data assessed included baseline characteristics, preoperative and postoperative best-corrected visual acuity (BCVA), ERM recurrence rate during follow-up, and complications arising during follow-up. Results: PPV resulted in a statistically significant improvement in BCVA (20/61 preoperatively, 20/41 1 year postoperatively, and 20/45 at the end of follow-up). Mean duration of follow-up was 66.3 months (range, 26-89). Forty-one of 45 (91%) eyes had improved or stable vision, while 4/45 (8.9%) had worse vision. ERMs recurred in 12/45 eyes (26.7%), of which 1/45 (2.2%) required reoperation. The remaining 11 recurrent ERMs were documented as visually insignificant. Mean time to ERM recurrence was 29.3 months (range, 4-72). Conclusions: In one of the longest mean follow-up studies to date, small-gauge PPV for ERM and ILM removal results in statistically significant and stable long-term visual improvement. Despite ILM removal, ERMs did recur in a substantial proportion of patients, though the vast majority were not visually significant.

China has the largest amount of extra-high earth-rock dams over 200 m in the world. Complicated construction and severe operation conditions pose great difficulties and huge challenges in their construction and long-term safety. This paper introduces main research progresses in the areas of Key Technologies for Construction and Long-term Safety Protection of Extra High Earth-rock Dams under Complex Conditions. The particle-size effect, mesoscopic and deterioration mechanism of dam materials were studied throughly. The calculation model of rheological behavior of rockfill materials considering loading and creep coupling effect was established. The numerical simulation method for complex contacting problems in high earth-rock dams was developed using computational contact mechanics, and was used in studying the damage mechanism of concrete slabs and galleries. Testing apparatus conducting deformation-seepage coupling experiments were fabricated, and were used to investigate the permeability characteristics of core materials, the performance of anti-seepage systems in dam body and foundation. An equivalent density method was proposed to evaluate the in-situ density of overburden materials based on pressuremeter tests both in laboratory and field. New compound structure, modulus increasing technology, slab design method and water-stop materials for extra-high concrete face rockfill dams were studied, and safety evaluation and control standards were proposed for the demonstrating Dashixia project. The relevant results have provided technological supports for the two demonstrating projects, i.e. Rumei and Dashixia extra-high earth-rock dams, improving considerably the construction level and long-term safety of extra-high earth-rock dams.

This chapter on therapeutic drift with antenatal steroids will make the case that this pilar of treatment to improve the outcomes of preterm infants, despite multiple Randomized Control Trials (RCTs) and meta-analysis, has multiple gaps in solid clinical data to support any expanded use of Antenatal Corticosteroids (ACS). A basic problem is that agents used for ACS have never been evaluated to minimize fetal exposures. Based on the premise that all drug exposure to the fetus should be minimized and only used when necessary, ACS is a potent developmental modulator that has never been evaluated to minimize the dose and duration of fetal exposure. The use of ACS is expanding to late preterm infants where the benefit is modest, to elective C-sections, and periviable fetuses, with minimal RCT data of long-term benefit. Relevant animal experiments demonstrate that much lower doses will induce lung maturation in sheep and primates. Another area of drift in the use of ACS is based on the assumption that the old RCT data accurately predict the magnitude of benefit when ACS is used today with entirely different OB and neonatal care strategies to improve outcomes. We do not have data that demonstrate the effectiveness of ACS in very low resource environments, where most of the preterm mortality occurs. The final concern is the risk of ACS to the infant and child. Short-term risks are minimal but dysmaturation effects of ACS on multiple organ systems (lung, heart, brain, and kidney) may result in disease presentation in later life.

Background Age-related changes affecting facial areas can be corrected using minimally invasive dermal fillers. The use of polycaprolactone-dermal filler (PCL-filler) in aesthetics is increasing. Objective To evaluate the long-term safety and efficacy of the PCL-filler, in a European, multicenter, prospective study. Materials and methods Subjects (n = 90) with moderate/severe nasolabial folds (Wrinkle Severity Rating Scale [WSRS]: 3 to 4) were treated on Day 0 with a single injection of similar volume on each side; safety and efficacy assessments were performed over an 18-month period. In 1 of the 3 study centers, safety was evaluated at 30 months. Results At Month 12 (M12; primary endpoint), 84% of subjects showed a ≥1-point improvement on the WSRS (M6: 92%; M18: 64%). From the investigator/subject's evaluation, from Day 7 to M12, Global Aesthetic Improvement was reported for >90% of subjects, with the effect maintained for up to 18 months in >80% of patients. Subjects/investigators reported high satisfaction and skin quality improvement. Most of the immediate injection-site reactions disappeared after 2 to 4 days. No severe or unexpected adverse events were reported. Conclusion This study demonstrated the long-term safety and efficacy of the PCL-filler, with safety confirmed for up to 30 months.

According to the 'Act on the Organizational Restructuring in the Field of Radioactive Waste Disposal' the BGE was established in 2016. The amended 'Repository Site Selection Act' (StandAG) came into force in July 2017 and forms the base for the site selection by clearly defining the procedure. According to the StandAG the BGE implements the participative, science-based, transparent, self-questioning and learning procedure with the overarching aim to identify the site for a high-level radioactive waste (HLW) repository in a deep geological formation with best possible safety conditions for a period of one million years.The German site selection procedure consists of three phases, of which Phase 1 is divided into two steps. Starting with a blanc map of Germany, the BGE completed Step 1 in September 2020 and identified 90 individual sub-areas that provide favorable geological conditions for the safe disposal of HLW in the legally considered host rocks; rock salt, clay and crystalline rock. Based on the results of Step 1, the on-going Step 2 will narrow down these sub-areas to siting regions for surface exploration within Phase 2 (§ 14 StandAG). Central to the siting process are representative (Phase 1), evolved (Phase 2) and comprehensive (Phase 3) preliminary safety assessments according to § 27 StandAG.The ordinances on 'Safety Requirements' and 'Preliminary Safety Assessments' for the disposal of high-level radioactive waste from October 2020 regulate the implementation of the preliminary safety assessments within the different phases of the siting process. Section 2 of the 'Safety Requirements' ordinance provides requirements to evaluate the long-term safety of the repository system; amongst others, it states that all potential effects that may affect the long-term safety of the repository system need to be systematically identified, described and evaluated as “expected” or “divergent” evolutions. Additionally, the ordinance on 'Preliminary Safety Assessments' states in § 7, amongst others, that the geoscientific long-term prediction is a tool to identify and to evaluate geogenic processes and to infer “expected” and “divergent” evolutions from those. Hence, considering the time period of one million years for the safe disposal of the HLW and the legal requirements, it is essential to include long-term climate evolution in the German site selection process to evaluate the impact of various climate-related scenarios on the safety of the whole repository system.To better understand and evaluate the influence of climate-related processes on the long-term safety of a HLW repository, climate-related research will be a part of the BGE research agenda. Potential research needs may address i) processes occurring on glacial – interglacial timescales (e.g. the inception of the next glaciation, formation and depth of permafrost, glacial troughs, sub-glacial channels, sea-level rise, orbital forcing) and their future evolutions, ii) effects on the host rocks and the barrier system(s) as well as iii) the uncertainties related to these effects but also to general climate models and predictions.

Background: Azathioprine is a common first-line therapy for neuromyelitis optica spectrum disorder (NMOSD). Objective: The aim of this study was to determine whether long-term treatment (>10 years) with azathioprine is safe in NMOSD. Methods: We conducted a retrospective medical record review of all patients at the School of Medicine of the University of São Paulo (São Paulo, Brazil) who fulfilled the 2015 international consensus diagnostic criteria for NMOSD and were treated with azathioprine for at least 10 years. Results: Out of 375 patients assessed for eligibility, 19 were included in this analysis. These patients’ median age was 44 years (range=28-61); they were mostly female (17/19) and AQP4-IgG seropositive (18/19). The median disease duration was 15 years (range=10-39) and most patients presented a relapsing clinical course (84.2%). The median duration of treatment was 11.9 years (range=10.0-23.8). The median annualized relapse rates (ARR) pre- and post-treatment with azathioprine were 1 (range=0.1-2) and 0.1 (range=0-0.35); p=0.09. Three patients (15.7%) had records of adverse events during the follow-up, which consisted of chronic B12 vitamin deficiency, pulmonary tuberculosis and breast cancer. Conclusion: Azathioprine may be considered a safe agent for long-term treatment (>10 years) of NMOSD, but continuous vigilance for infections and malignancies is required. RESUMO Introdução: A azatioprina é um tratamento comum de primeira linha para os transtornos do espectro neuromielite óptica (NMOSD). Objetivo: Este estudo visou determinar a segurança do tratamento a longo prazo (>10 anos) da NMOSD com a azatioprina. Métodos: Foi realizada revisão retrospectiva de todos os prontuários de pacientes que preenchiam critérios de NMOSD de acordo com o “International Consensus Diagnostic Criteria for NMOSD” de 2015 em uso de azatioprina por ao menos 10 anos matriculados no ambulatório de Doenças Desmielinizantes do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Resultados: De 375 pacientes avaliados, 19 preencheram critérios de inclusão para análise. A mediana de idade foi de 44 anos (variância=28-61); os pacientes eram predominantemente do sexo feminino (17/19) e AQP4-IgG soropositivos (18/19). A mediana do tempo de duração de doença foi 11,9 anos (variância=10,0-23,8), a mediana da taxa anualizada de surtos pré e pós-tratamento foi de 1 (variância=0,1-2) e 0,1 (variância=0-0,35), p=0,09. Três pacientes (15,7%) apresentaram registro de eventos adversos durante o seguimento: deficiência crônica de vitamina B12, tuberculose pulmonar e câncer de mama. Conclusão: A azatioprina provavelmente pode ser considerada segura para o tratamento a longo prazo (>10 anos) da NMOSD, porém vigilância contínua de neoplasias e infecções é necessária.

Context Growth hormone (GH) treatment has a generally good safety profile; however, concerns about increased mortality risk in adulthood have been raised. Objective This work aims to assess the long-term safety of GH treatment in clinical practice. Methods Data were collected from 676 clinics participating in 2 multicenter longitudinal observational studies: the NordiNet International Outcome Study (2006-2016, Europe) and ANSWER Program (2002-2016, USA). Pediatric patients treated with GH were classified into 3 risk groups based on diagnosis. Intervention consisted of daily GH treatment, and main outcome measures included incidence rates (events/1000 patient-years) of adverse drug reactions (ADRs), serious adverse events (SAEs), and serious ADRs, and their relationship to GH dose. Results The combined studies comprised 37 702 patients (68.4% in low-risk, 27.5% in intermediate-risk, and 4.1% in high-risk groups) and 130 476 patient-years of exposure. The low-risk group included children born small for gestational age (SGA; 20.7%) and non-SGA children (eg, with GH deficiency; 79.3%). Average GH dose up to the first adverse event (AE) decreased with increasing risk category. Patients without AEs received higher average GH doses than patients with more than one AE across all groups. A significant inverse relationship with GH dose was shown for ADR and SAE incidence rates in the low-risk group (P = .003 and P = .001, respectively) and the non-SGA subgroup (both P = .002), and for SAEs in the intermediate- and high-risk groups (P = .002 and P = .05, respectively). Conclusions We observed no indication of increased mortality risk nor AE incidence related to GH dose in any risk group. A short visual summary of our work is available (1).

Objective: The study shows the long-term effectiveness, safety, and quality of life after Vibrant Soundbridge (VSB) implantation in sensorineural hearing loss (SNHL) using the short process coupler (SP) or the long process coupler (LP). Methods: This retrospective study evaluated 77 VSB cases. Follow-up (F/U) time-dependent objective measurements (audiological outcomes), subjective data collection (quality-of-life questionnaire), and safety measures are presented. Results: Sixty-two ears were included in the analysis with up to 116 months of postsurgical F/U data (mean 32.15 ± 37.97 months LP and SP coupler). Fifty-three ears (13 bilateral cases) received the LP coupler and 9 subjects the SP coupler. The post-operative bone conduction thresholds remained stable and, in both groups, p = 0.559 and p = 0.088, respectively). The functional gain was not significantly different (p > 0.05) with a mean of 20.91 ± 9.77 and 17.19 ± 5.75 for LP and SP coupler, respectively. The utility score deciphered from the Assessment of Quality-of-life Questionnaire-8 dimensions revealed a mean score of 0.75 ± 0.16 which is not significantly different to the age- and sex-matched healthy control group with 0.81 ± 0.02 (p = 0.3547). Conclusion: The Incus Vibroplasty utilizing both couplers is a safe and effective method to treat mild-to-severe SNHL. Both fixation methods of the floating mass transducer exhibit good clinical and audiological outcomes with high patient quality of life. The SP coupling method can be a good alternative when the long process is anatomically inaccessible, or the approach is limited due to anatomical reasons.

Background and Aims Etrasimod is an oral, selective, sphingosine 1-phosphate receptor modulator. In a phase 2, randomised, double-blind, placebo-controlled trial in adults with moderately-to-severely active ulcerative colitis [OASIS], etrasimod 2 mg provided significant benefit versus placebo and was generally well tolerated. This open-label extension [OLE] evaluated safety and efficacy of etrasimod for up to 52 weeks. Methods In OASIS, 156 patients received etrasimod 1 mg, etrasimod 2 mg, or placebo, once daily for 12 weeks. After completing OASIS, patients could enrol in the OLE and receive etrasimod 2 mg for an additional 34–40 weeks. Results In all, 118 patients enrolled in the OLE; 112 patients received etrasimod 2 mg at any point and were evaluated for safety and efficacy. A total of 92 [82%] patients who received etrasimod 2 mg in the OLE completed the study. Treatment-emergent adverse events occurred in 60% [67/112] of patients receiving etrasimod 2 mg at any time, most commonly worsening ulcerative colitis and anaemia; 94% of adverse events were mild/moderate. At end of treatment, 64% of patients met the criteria for clinical response, 33% for clinical remission, and 43% for endoscopic improvement. Week 12 clinical response, clinical remission, or endoscopic improvement was maintained to end of treatment in 85%, 60%, or 69% of patients, respectively. Steroid-free clinical remission occurred in 22% of overall patients. Conclusions In this long-term extension study, etrasimod 2 mg demonstrated a favourable safety profile. Most patients with clinical response, clinical remission, or endoscopic improvement at Week 12 maintained that status to end of treatment.

Introduction and Objectives Dupilumab, a fully human monocolonal antibody, blocks the shared receptor component for interleukin (IL)–4 and IL–13, key and central drivers of type 2 inflammation in multiple diseases. The efficacy and safety up to 52 weeks of dupilumab in asthma have been demonstrated in phase 2 and phase 3 studies. We assess the long-term safety and efficacy of dupilumab in the open-label extension (OLE) LIBERTY ASTHMA TRAVERSE study (NCT02134028) in adult and adolescent patients who had completed a dupilumab asthma study (phase 2b DRI, phase 2 EXPEDITION, phase 3 QUEST, or phase 3 VENTURE). Methods Patients with moderate-to-severe or oral corticosteroid (OCS)-dependent severe asthma received add–on subcutaneous dupilumab 300 mg every 2 weeks (q2w), up to 96 weeks. Treatment-emergent adverse events (TEAEs), annualized rate of severe asthma exacerbations (AER) during the treatment period, and change from parent study baseline (PSBL) in forced expiratory volume in 1 second (FEV1) and biomarkers up to Week 96 were assessed. Results Of 2,930 patients randomized in the parent studies, 78% enrolled into the OLE; of 2,282 patients enrolled and exposed in the OLE, 96% had a study duration of 48 weeks and 54% had a study duration of 96 weeks. Long-term safety profile was consistent with the parent studies (table 1). The low unadjusted AER and improvement in FEV1 observed in the parent studies were sustained during the OLE. Similar efficacy was seen in patients with elevated type 2 biomarkers from DRI/QUEST. By Week 96, blood eosinophils decreased to below PSBL levels in patients from DRI/QUEST and were near PSBL levels in patients from VENTURE; total IgE levels decreased by 82% (median percent change from PSBL). Conclusions Long-term use of dupilumab was well tolerated and showed sustained efficacy in asthma patients up to 96 weeks.

Enzyme replacement therapy in Fabry disease has been available in Japan since 2004. Two post-authorization safety studies were conducted to evaluate agalsidase beta in Japanese patients with Fabry disease in real-world practice. The Special Drug Use Investigation monitored the long-term safety and efficacy of agalsidase beta, and the Drug Use Investigation monitored safety in patients not participating in the Special Drug Use Investigation. Safety and efficacy evaluations included adverse drug reactions (ADRs), infusion-associated reactions and hypersensitivity reactions, and change in blood GL-3 level over time. Of 396 patients in the aggregated data set, safety and efficacy analysis sets comprised 307 and 196 patients, respectively. ADRs occurred in 93 (30.3%) patients and serious ADRs occurred in 25 (8.1%) patients, with general disorders and administration site conditions (n=55, 17.9%), nervous system disorders (n=30, 9.8%) and skin and subcutaneous tissue disorders (n=23, 7.5%) the most common. Reductions in blood GL-3 levels occurred over the study, irrespective of age or disease phenotype. Agalsidase beta demonstrated acceptable safety and tolerability, with sustained reductions in blood GL-3 levelsin Japanese patients with Fabry disease in real-world clinical practice NCT00233870/AGAL03004 (Special Drug Use Investigation of Agalsidase beta)

PURPOSE The aim of this study was to evaluate the safety and efficacy of tacrolimus 0.1% eye drops in a large population of pediatric patients affected by a severe form of vernal keratoconjunctivitis (VKC) who responded poorly to cyclosporine eye drops. METHODS This is a retrospective study based on standardized clinical charts and data collection of consecutive patients affected by severe VKC who responded poorly to cyclosporine eye drops topical treatment but treated with tacrolimus 0.1% eye drops with a follow-up of 18 months. Four clinical signs were graded for analysis: hyperemia, tarsal papillae, giant papillae, and limbal papillae. The blood tests for kidney and liver function and the tacrolimus level were studied. Visits were scheduled at baseline and at 3, 6, 12, and 18 months. Patients received tacrolimus 0.1% eye drops in both eyes 2 times daily. RESULTS Four hundred thirty-one patients were included. Three hundred twenty-five patients were affected by a seasonal form, whereas the remaining 106 by a perennial form. Statistical analysis on each single score showed a positive relevance (P < 0.001) from baseline to all other visits. No local or systemic complications were recorded. CONCLUSIONS Tacrolimus has been proposed as a treatment for severe forms of VKC. This study has confirmed the safety and efficacy of tacrolimus 0.1% eye drops in a large pediatric population of patients affected by a severe form of VKC who responded poorly to cyclosporine eye drops.

Tolvaptan slows kidney function decline in patients with autosomal dominant polycystic kidney disease (ADPKD) at risk of rapid progression. In the 3-year Tolvaptan Efficacy and Safety in Management of ADPKD and Its Outcomes (TEMPO) 3:4, 2-year extension to TEMPO 3:4 (TEMPO 4:4), and 1-year Replicating Evidence of Preserved Renal Function: An Investigation of Tolvaptan Safety and Efficacy in ADPKD (REPRISE) trials, aquaretic adverse events were common. Serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) elevations occurred in all three studies. Three patients met Hy Law criteria (ALT or AST more than three times and total bilirubin more than two times the upper limit of normal) for severe drug-induced liver injury (two in TEMPO 3:4 and one in TEMPO 4:4). In REPRISE, liver enzyme monitoring frequency was increased to monthly, with no Hy Law cases. A long-term, phase 3 safety study has further characterized tolvaptan safety.Subjects who completed TEMPO 4:4, REPRISE, or other tolvaptan trials could enroll in this prospective, multinational, open-label safety study. Assessments included monthly liver enzyme testing during the first 18 months of tolvaptan exposure and every 3 months thereafter.Among 1803 subjects, median tolvaptan exposure during the extension was 651 days (interquartile range, 538-924), and cumulative exposure (extension and previous trials) was ≤11 years. Subjects entering from REPRISE placebo experienced more aquaretic adverse events compared with subjects from TEMPO 4:4 or REPRISE tolvaptan (No new safety signals emerged during this long-term extension. Monthly liver function testing for the first 18 months of treatment appeared to enable effective detection and management of transaminase elevations.Open Label Extension of TEMPO 3:4, NCT02251275.
