The indomethacin/prochlorperazine/caffeine fixed combination (Difmetré®) combines the NSAID indomethacin with the phenothiazine antiemetic prochlorperazine and caffeine. It is currently available as two oral (effervescent tablet and coated tablet) and two rectal (suppository and low-dose suppository) formulations. Oral and rectal formulations of indomethacin/prochlorperazine/caffeine were effective and generally well tolerated in the treatment of migraine and episodic tension-type headache (TTH) in adult patients participating in randomized, multicentre, active-comparator controlled studies. For the most part, the efficacy of oral indomethacin/prochlorperazine/caffeine did not significantly differ from that of oral sumatriptan in patients with migraine and oral nimesulide in patients with episodic TTH. With rectal administration, indomethacin/prochlorperazine/caffeine was, in general, significantly more effective than sumatriptan in patients with migraine. Thus, oral and rectal formulations of indomethacin/prochlorperazine/caffeine provide a further option in the acute treatment of migraine and in the treatment of episodic TTH in adult patients.

Estradiol valerate/dienogest is an oral contraceptive for women that combines the natural estrogen estradiol with the 19-nortestosterone derivative dienogest in a four-phasic formulation. Estradiol valerate/dienogest demonstrated contraceptive efficacy in a large (n = 1377), noncomparative, multicentre study in women aged 18-50 years, with 13 pregnancies over 1797.5 women-years of exposure generating an unadjusted Pearl Index (PI) of 0.73 (upper limit of 95% CI 1.24) [primary endpoint]. Six of the pregnancies were attributed to method failure, resulting in an adjusted PI, based on 1786.5 women-years of exposure, of 0.34 (upper limit of 95% CI 0.73). In a double-blind study in 798 women aged 18-50 years, estradiol valerate/dienogest and ethinylestradiol/levonorgestrel demonstrated an acceptable bleeding pattern and level of cycle control, according to several co-primary endpoints. As reported in the UK manufacturer's summary of product characteristics, the unadjusted PI for women aged 18-35 years or 18-50 years in a pooled analysis of clinical studies was 1.01 (upper limit of 95% CI 1.59) and 0.79 (upper limit of 95% CI 1.23). This pooled analysis of three studies excluded those pregnancies occurring within 14 days of the cessation of therapy. Estradiol valerate/dienogest was generally well tolerated in this population, with the nature of adverse events generally similar across the studies and between estradiol valerate/dienogest and ethinylestradiol/levonorgestrel.

Oral dronedarone is a non-iodinated benzofurane derivative structurally related to amiodarone. Although it is considered a class III antiarrhythmic agent like amiodarone, it demonstrates multi-class electrophysiological activity. Data from the ATHENA study demonstrated that patients receiving oral dronedarone 400 mg twice daily for 12-30 months had a significantly lower risk of experiencing first hospitalization due to a cardiovascular event or death from any cause than those receiving placebo. Dronedarone exhibited rate- and rhythm-controlling properties in patients with atrial fibrilation (AF) or atrial flutter, significantly reducing the risk of a first recurrence of AF versus placebo following 12 months' therapy in the ADONIS and EURIDIS studies. In the ERATO study, dronedarone was also significantly more effective than placebo in terms of ventricular rate control. Furthermore, the beneficial effects of oral dronedarone on ventricular rate control were maintained during exercise and sustained with continued therapy. Oral dronedarone was generally well tolerated in the treatment of adult patients with AF and/or atrial flutter in clinical studies. The incidence of diarrhoea, nausea, bradycardia, rash and QT-interval prolongation was significantly higher with oral dronedarone than placebo in the large ATHENA study; however, serious cardiac-related adverse events were observed in <1% of oral dronedarone recipients.

Oral omega-3 ethylester concentrate (omega-3 EEC) [Omacor; Lovaza] is indicated as an adjuvant therapy in adult patients for secondary prevention post-myocardial infarction (MI) and the treatment of hypertriglyceridaemia in the majority of European countries, and for the treatment of hypertriglyceridaemia (serum triglyceride levels > or =5.6 mmol/L [> or =500 mg/dL]) in the US. Each 1000 mg capsule of omega-3 EEC consists of 460 mg of ethyl eicosapentaenoic acid and 380 mg of ethyl docosahexaenoic acid. The addition of omega-3 EEC 1000 mg/day to standard medical therapy in the GISSI-Prevenzione study provided secondary prevention benefits in post-MI adult patients. The benefits were attributable to reductions in death and cardiovascular death (including sudden death). Additional data examining the extent and mechanisms of the cardiovascular benefit conferred by omega-3 EEC in secondary prevention would be useful. As an adjunct to diet, monotherapy with omega-3 EEC 4000 mg/day significantly reduced triglyceride levels in patients with hypertriglyceridaemia, although limited data suggest it was less effective than gemfibrozil. In addition, omega-3 EEC 4000 mg/day plus simvastatin or atorvastatin reduced triglyceride, non-high-density lipoprotein cholesterol (non-HDL-C) and/or very-low-density lipoprotein cholesterol (VLDL-C) levels to a significantly greater extent than placebo plus simvastatin or atorvastatin. Omega-3 EEC was generally well tolerated both as secondary prevention post-MI and in the treatment of hypertriglyceridaemia. Thus, omega-3 EEC is a useful option both in secondary prevention post-MI and the treatment of hypertriglyceridaemia. [ABSTRACT FROM AUTHOR]

Mavorixafor (XOLREMDI™) is an oral, selective C-X-C chemokine receptor 4 (CXCR4) antagonist developed by X4 Pharmaceuticals that blocks the binding of C-X-C chemokine ligand 12 (also known as stromal derived factor-1) to CXCR4.

Futibatinib (LYTGOBI ® ) is an oral small molecule compound that selectively, irreversibly and potently inhibits the tyrosine kinase activity of fibroblast growth factor receptor (FGFR)1-4. It is approved in the EU, Japan and the USA for the treatment of adults with locally advanced or metastatic cholangiocarcinoma (CCA) harbouring an FGFR2 fusion or rearrangement who have progressed following systemic therapy. In the phase II part (FOENIX-CCA2) of a multinational phase I/II study in this patient population, monotherapy with futibatinib 20 mg once daily was associated with clinically meaningful and durable responses, sustained health-related quality of life (HR-QOL), and a manageable safety profile with supportive care and as-needed dose modifications. Indeed, hyperphosphataemia (the most common all grade and grade 3 treatment-related adverse event) was manageable with phosphate-lowering therapy and dose reductions or interruptions. Although further efficacy and tolerability data are expected, current evidence indicates that futibatinib is a valuable targeted therapy option for adults with locally advanced or metastatic CCA harbouring an FGFR2 fusion or rearrangement who have progressed following systemic therapy, a patient population with limited treatment options and poor life expectancy., (© 2024.

Ruxolitinib cream 1.5% (OPZELURA™) is a topical formulation of ruxolitinib, a potent, selective inhibitor of Janus kinase (JAK)1 and JAK2. The targeting of these kinases is associated with therapeutic benefits in patients with atopic dermatitis (AD). In two identically designed, multinational, phase III studies in patients aged ≥ 12 years with mild to moderate AD, ruxolitinib cream 1.5% improved measures of disease severity, pruritus and sleep disturbance relative to vehicle cream when applied twice daily for 8 weeks. Disease severity was controlled for the next 44 weeks when applied as needed to active lesions. Ruxolitinib cream 1.5% was well tolerated in this patient population; its safety profile was similar to that of vehicle cream over the short term, with the types of treatment-emergent adverse events typical of those seen in the vehicle-controlled period over the longer term. Moreover, application site treatment-emergent adverse events indicative of skin tolerability issues (e.g. stinging/burning sensation) were infrequent and no safety findings suggestive of systemic JAK inhibition were identified. Although further longer-term data would be of use, ruxolitinib cream 1.5% provides an alternative to established topical agents (e.g. corticosteroids and calcineurin inhibitors) for the treatment of mild to moderate AD in adults and adolescents., (© 2022.

Baricitinib (Olumiant ® ) is an oral small molecule inhibitor of Janus kinase (JAK)1 and JAK2, which have been implicated in the pathogenesis of atopic dermatitis (AD). In phase III studies in adults with moderate to severe AD who were inadequately controlled with topical corticosteroids (TCS) or systemic treatments (e.g. ciclosporin), or for whom these therapies were not advisable, baricitinib, alone or in combination with TCS, achieved significant and/or clinically relevant improvements in multiple measures of disease severity, pruritus, skin pain, sleep disturbance and health-related quality of life (HR-QOL) over 16 weeks. Benefit onset was rapid, with efficacy generally sustained over the longer term (treatment duration ≤ 68 weeks). In this patient population, the safety profile of baricitinib was consistent with that established in the moderate to severe rheumatoid arthritis (RA) population. Although further longer-term data would be beneficial, current evidence indicates that baricitinib, alone or in combination with TCS, provides an oral alternative to subcutaneous biologics for the treatment of moderate to severe AD in adults who are candidates for systemic therapy., (© 2022.

Survival motor neuron 1 (SMN1), located on chromosome 5q, encodes the survival motor neuron (SMN) protein. A deletion or mutation in SMN1 results in a rare neuromuscular disorder: 5q spinal muscular atrophy (SMA). In such patients, SMN protein production relies solely on SMN2. Nusinersen (Spinraza ® ) is a modified antisense oligonucleotide approved for the treatment of 5q SMA. Administered intrathecally, it modifies SMN2 pre-messenger RNA splicing, thereby increasing full-length SMN protein levels. Interim analyses from an ongoing phase II study suggest substantial clinical benefits with nusinersen initiation in presymptomatic patients. In phase III studies, nusinersen achieved significant and/or clinically relevant improvements in motor function in symptomatic patients with infantile- and later-onset 5q SMA, and significantly improved event-free survival and overall survival in patients with infantile-onset 5q SMA. Longer term (up to a median of ≈ 6 years of available data), motor function was maintained or improved in symptomatic patients. Nusinersen had a favourable safety profile in clinical studies in presymptomatic and symptomatic patients. Real-world experience supports the effectiveness, safety and tolerability of nusinersen in symptomatic patients of all ages. Thus, nusinersen remains an important treatment option among a broad range of 5q SMA patients., (© 2021. Springer Nature Switzerland AG.)

Amikacin liposome inhalation suspension (ALIS) [Arikayce ® Liposomal (EU); Arikayce ® (USA)], a liposomal suspension of the aminoglycoside amikacin (590 mg) for nebulization via the Lamira ® Nebulizer System, is available as add-on therapy for treatment-refractory Mycobacterium avium complex (MAC) lung disease in adults who have little or no alternative treatment options. Its addition to guideline-based therapy (GBT) significantly improved the likelihood of achieving sputum culture conversion (defined as three consecutive monthly MAC-negative sputum cultures) by month 6 relative to GBT alone in adults with treatment-refractory MAC lung disease, with the conversion response maintained over up to 12 months' therapy and at 3 months' post treatment in significantly higher proportions of ALIS plus GBT than GBT alone recipients. ALIS as an add-on therapy to GBT was associated with an increased risk of respiratory adverse reactions compared with GBT alone, but treatment-emergent adverse events associated with systemic amikacin exposure were uncommon.

Brigatinib (Alunbrig ® ) is an oral, potent and selective anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) tyrosine kinase inhibitor approved for treating adults with advanced ALK-positive non-small-cell lung cancer (NSCLC) not previously treated with an ALK inhibitor. In a multinational, phase III study (ALTA-1L) in this patient population, brigatinib significantly improved median blinded independent review committee-assessed progression-free survival (PFS), the confirmed objective response (OR) rate and the confirmed intracranial OR rate compared with crizotinib. Its tolerability profile in this study was manageable and no new safety concerns were identified. Although final analysis data are awaited with interest, brigatinib therapy extends the first-line treatment options available for standard of care in this patient population, including patients with CNS metastases.

Tafasitamab (tafasitamab-cxix; MONJUVI ® ) is an Fc-modified (i.e. two amino acid substitutions within the Fc region, resulting in increased Fcγ receptor affinity), humanized, anti-CD19 monoclonal antibody. Developed by MorphoSys AG, under a license from Xencor, it received accelerated approval (in July 2020) for use in combination with lenalidomide as a treatment for adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplantation (ASCT). It is the first therapy to be approved as a second-line treatment for this patient population in the USA. The recommended dose of tafasitamab is 12 mg per kg of bodyweight, administered via an intravenous infusion. A regulatory assessment for tafasitamab plus lenalidomide for the treatment of adults with relapsed or refractory DLBCL is currently underway in the EU. Tafasitamab is also being clinically investigated as a therapeutic option in various other B-cell malignancies, including follicular lymphoma and other indolent non-Hodgkin's lymphoma. This article summarizes the milestones in the development of tafasitamab leading to this first approval for its use in combination with lenalidomide in adults with relapsed or refractory DLBCL.

Apalutamide (Erleada ® ) is an oral selective androgen receptor (AR) inhibitor that binds directly to the ligand-binding domain of the AR. It is approved in the EU and the USA for the treatment of adult men with metastatic castration-sensitive prostate cancer (mCSPC). In a multinational, phase III study (TITAN) in this patient population, the addition of apalutamide (240 mg once daily) to androgen deprivation therapy (ADT) significantly improved median radiographic progression-free survival (rPFS), median overall survival (OS) and the median time to cytotoxic chemotherapy, while maintaining health-related quality of life (HR-QOL) and not substantially differing from placebo plus ADT in safety. Although mature OS data are awaited with interest, the addition of apalutamide to ADT extends the treatment options available for standard of care in adult men with mCSPC.

Pemigatinib (PEMAZYRE™), a small molecule inhibitor of fibroblast growth factor receptor (FGFR) 1, FGFR2 and FGFR3, received accelerated approval in April 2020 in the USA for the treatment of adults with previously treated, unresectable, locally advanced or metastatic cholangiocarcinoma and a FGFR2 fusion or other rearrangement, as detected by a US FDA-approved test. Developed by Incyte Corporation, it is the first targeted treatment for cholangiocarcinoma in the USA. The recommended dosage of pemigatinib is 13.5 mg once daily, administered orally with or without food, on days 1-14 of a 21-day cycle until disease progression or unacceptable toxicity. Pemigatinib received orphan designation for the treatment of myeloid/lymphoid neoplasms with eosinophilia and rearrangement of PDGFRA, PDGFRB or FGFR1, or with PCM1-JAK2 in August 2019 in the USA. A regulatory assessment for pemigatinib as a treatment for adults with locally advanced or metastatic cholangiocarcinoma and a FGFR2 fusion or rearrangement that is relapsed or refractory after ≥ 1 line of systemic therapy is underway in the EU. Pemigatinib is also undergoing clinical development in various countries worldwide for use in several other FGFR-driven malignancies (e.g. solid tumour, urothelial carcinoma). This article summarizes the milestones in the development of pemigatinib leading to this first approval for the treatment of adults with previously treated, unresectable, locally advanced or metastatic cholangiocarcinoma and a FGFR2 fusion or other rearrangement, as detected by a US FDA-approved test.

Dupilumab (Dupixent ® ) is a fully human IgG4 monoclonal antibody against the interleukin (IL)-4 receptor α (IL-4Rα) subunit, which is shared by the type I IL-4 and the type II IL-4/IL-13 receptor complexes. By binding to and blocking this subunit, dupilumab inhibits IL-4 and IL-13, which are the major drivers of human type 2 inflammatory disease [e.g. asthma, atopic dermatitis and chronic rhinosinusitis with nasal polyps (CRSwNP)]. Dupilumab, administered subcutaneously, is the first biological therapy to be approved for the treatment of adults with inadequately controlled CRSwNP in the EU and the USA. In two placebo-controlled, multinational, phase III studies of 24 and 52 weeks' duration, the addition of dupilumab (300 mg every 2 weeks) to the intranasal corticosteroid treatment of adults with severe, inadequately controlled CRSwNP was generally well tolerated and improved nasal polyp size, sinus opacification and health-related quality of life (HR-QOL), relieved the major symptoms of CRSwNP (nasal congestion or obstruction, nasal discharge and loss of smell) and reduced the use of systemic corticosteroids and the need for nasal polyp surgery. Improvements in nasal polyp size, sinus opacification and nasal congestion or obstruction were achieved regardless of the presence of comorbid asthma or NSAID-exacerbated respiratory disease, or a history of previous nasal polyp surgery, with patients with comorbid asthma also demonstrating improvements in lung function and asthma control regardless of their baseline eosinophil count. Thus, add-on subcutaneous dupilumab is a valuable treatment option for adults with inadequately controlled CRSwNP.

Subcutaneous MYL1501D insulin glargine 100 U/mL (hereafter referred to as MYL1501D insulin glargine) [Semglee ® ] is a long-acting human insulin analogue approved as a biosimilar of insulin glargine 100 U/mL (hereafter referred to as reference insulin glargine 100 U/mL) [Lantus ® ] in various countries, including those of the EU for the treatment of diabetes mellitus in patients aged ≥ 2 years, as well as Japan for diabetes where insulin therapy is indicated. MYL1501D insulin glargine has similar physicochemical characteristics and biological properties to those of EU- and US-sourced reference insulin glargine 100 U/mL, with the bioequivalence of pharmacodynamic and pharmacokinetic parameters between these agents shown in adults with type 1 diabetes. Once-daily MYL1501D insulin glargine demonstrated noninferior glycaemic efficacy to that of once-daily reference insulin glargine 100 U/mL in adults with type 1 or 2 diabetes, with its glycated haemoglobin-lowering benefits maintained over the longer-term (52 weeks) and unaffected by previous insulin exposure. Switching between MYL1501D insulin glargine and reference insulin glargine 100 U/mL did not appear to impact glycaemic efficacy in adults with type 1 diabetes. MYL1501D insulin glargine was well tolerated, demonstrating a safety and immunogenicity profile similar to that of reference insulin glargine 100 U/mL in patients with type 1 and 2 diabetes, and in those with type 1 diabetes switching between the two agents. As expected, hypoglycaemia was the most frequently reported treatment-emergent adverse event. Thus, MYL1501D insulin glargine provides an effective biosimilar alternative for patients requiring insulin glargine therapy.

Collagenase Clostridium Histolyticum (hereafter referred to as CCH) [Xiaflex ® ; Xiapex ® ] is a mixture of two Clostridium histolyticum collagenases [AUX-I (a Class I clostridial collagenase) and AUX-II (a Class II clostridial collagenase)]. Administered by intralesional injection, it is available in various countries for the treatment of adult men with Peyronie's disease (PD). In two double-blind, multinational, phase III studies, CCH improved the physical (penile curvature) and psychological (patient-reported bother) aspects of PD in adult men. Such beneficial effects were also seen in two open-label, multinational, phase III studies, with potential benefits for patients' partners and maintained efficacy over up to 5 years additionally reported. Moreover, large real-world studies generally supported the therapeutic efficacy of CCH. CCH was generally well tolerated in these patient populations, with most treatment-related adverse events [TRAEs; most commonly penile haematoma (or 'bruising'), pain and swelling] being mild or moderate in severity, not serious and resolving without intervention. Moreover, the use of CCH was not associated with penile length shortening. Current evidence indicates that CCH is an effective, generally well tolerated and, compared with surgery, minimally invasive option for the treatment of adult men with PD.

A fixed-dose combination tablet of the cystic fibrosis transmembrane conductance regulator (CFTR) corrector tezacaftor and the CFTR potentiator ivacaftor with the next-generation CFTR corrector elexacaftor (hereafter referred to as elexacaftor/ivacaftor/tezacaftor) [Trikafta™] has been developed by Vertex Pharmaceuticals Inc. to treat patients with the most common cystic fibrosis mutation (F508del). Its use has been associated with statistically significant and/or clinically meaningful improvements in lung function and respiratory-related quality of life compared with comparator regimens (placebo or ivacaftor/tezacaftor) in multinational phase II and III studies, and in October 2019 elexacaftor/ivacaftor/tezacaftor was approved by the US FDA for the treatment of cystic fibrosis in patients aged ≥ 12 years who have ≥ 1 F508del mutation in the CFTR gene. A regulatory assessment for elexacaftor/ivacaftor/tezacaftor as a treatment for cystic fibrosis is underway in the EU. This article summarizes the milestones in the development of elexacaftor/ivacaftor/tezacaftor leading to this first approval for the treatment of cystic fibrosis in patients aged ≥ 12 years who have ≥ 1 F508del mutation in the CFTR gene.

An enteral suspension (ES)/intestinal gel formulation of levodopa/carbidopa (hereafter referred to as levodopa/carbidopa ES) [Duodopa ® (EU); Duopa™ (USA)] has been developed to overcome the fluctuating plasma levodopa concentrations associated with oral levodopa/carbidopa formulations. In various countries, including those of the EU (under the Mutual Recognition Procedure), it is approved for the treatment of advanced levodopa-responsive Parkinson's disease (PD) with severe motor fluctuations and hyperkinesia or dyskinesia when available combinations of Parkinson medicinal products have not given satisfactory results. In several other countries, including the USA, it is approved for the treatment of motor fluctuations in patients with advanced PD. In adults with advanced PD, levodopa/carbidopa ES improved motor fluctuations, activities of daily living and health-related quality of life (HR-QOL) during short-term (12-week) treatment, with the beneficial effects on motor fluctuations largely sustained over the longer term (up to 7 years). Levodopa/carbidopa ES was generally well tolerated in this patient population, with adverse events (AEs) associated with aging, advanced PD-related comorbidities, the procedure/device or dopaminergic therapy. Its safety profile was comparable to that of oral levodopa/carbidopa with respect to non-procedure/device-associated AEs; most procedure/device-associated AEs were consistent in nature and incidence with medically recognised complications of the procedure in non-PD patients. Current evidence indicates that levodopa/carbidopa ES is an effective and generally well tolerated option for the treatment of motor fluctuations in patients with levodopa-responsive advanced PD who are not being effectively managed with non-invasive therapies.

Rifamycin SV MMX ® (Aemcolo™; Relafalk™) is a novel oral formulation of the antibacterial rifamycin SV that uses MultiMatrix (MMX ® ) technology to enable colonic delivery. Specifically, the active ingredient (rifamycin SV) is released throughout the colon, where it acts locally in the intestinal lumen; systemic absorption is minimal. Rifamycin SV MMX ® exhibits antibacterial activity against a broad spectrum of clinically relevant enteropathogens and is available in the EU and the USA for the treatment of adults with traveller's diarrhoea. In two multinational, phase III studies, rifamycin SV MMX ® (400 mg twice daily for 3 days) effectively shortened the duration of non-dysenteric traveller's diarrhoea in adults, being significantly more effective than placebo and noninferior to ciprofloxacin in reducing median time to last unformed stool. As expected (given its poor systemic absorption), rifamycin SV MMX ® was well tolerated in this patient population, with the overall incidence of treatment-emergent adverse events generally similar to those of placebo and ciprofloxacin. Current evidence indicates that twice-daily rifamycin SV MMX ® is an effective and well tolerated treatment option for shortening the duration of non-dysenteric traveller's diarrhoea in adults.

Onasemnogene abeparvovec (onasemnogene abeparvovec-xioi; formerly AVXS-101; ZOLGENSMA ® ) is an adeno-associated viral vector-based gene therapy designed to deliver a functional copy of the human survival motor neuron (SMN) gene to the motor neuron cells of patients with spinal muscular atrophy (SMA). It has been developed by AveXis, a Novartis company, and was approved in May 2019 in the USA for the treatment of paediatric patients aged < 2 years with SMA and bi-allelic mutations in the SMN1 gene (the primary gene encoding survival motor neuron protein). Onasemnogene abeparvovec is the first gene therapy to be approved for SMA in the USA. The recommended dose is 1.1 × 10 14 vector genomes per kg of bodyweight, administered as a single intravenous infusion over 60 min. Regulatory assessments for this formulation of onasemnogene abeparvovec are underway in the EU and Japan; an intrathecal formulation is currently undergoing clinical development in the USA. This article summarizes the milestones in the development of onasemnogene abeparvovec leading to this first approval for the treatment of paediatric patients aged < 2 years with SMA and bi-allelic mutations in SMN1.
