Introduction/Background Chronic Hand Eczema (CHE) is a frequent inflammatory skin disease associated with pain, pruritus, and significant occupational, functional, social, and psychological burden. Delgocitinib is a topical pan-JAK inhibitor which showed a dose-dependent efficacy in adults with CHE in a Phase 2b trial. Objectives The objectives of this analysis were to study (1) the efficacy of twice-daily applications of delgocitinib cream 20 mg/g, as assessed by Investigator's Global Assessment for CHE treatment success (primary outcome), and the secondary outcomes ≥75%/≥90% improvement in Hand Eczema Severity Index and ≥4-point improvement in the Dermatology Life Quality Index, and (2) the safety of twice-daily applications of delgocitinib cream 20 mg/g compared with cream vehicle in the treatment of adults with moderate to severe CHE in a pooled analysis of the DELTA-1 and DELTA-2 trials. Methods In the Phase 3 DELTA-1 (NCT04871711) and DELTA-2 (NCT04872101) trials, adults with moderate to severe CHE were randomized 2:1 to twice-daily delgocitinib cream 20 mg/g or cream vehicle for 16 weeks. The primary endpoint was the Investigator's Global Assessment for CHE (IGA-CHE) treatment success at Week 16, defined as IGA-CHE score of 0/1 (clear/almost clear, i.e. no/barely perceptible erythema and no other signs), with a ≥2-step improvement from baseline. Key secondary endpoints included ≥75%/≥90% improvement in Hand Eczema Severity Index (HECSI-75/90) and ≥4-point improvement in the Dermatology Life Quality Index (DLQI). This DELTA-1 and -2 pooled analysis included 639 patients treated with delgocitinib cream and 321 with cream vehicle. Results At Week 16, a significantly greater proportion of delgocitinib-treated patients, versus cream vehicle, achieved IGA-CHE treatment success (24.3% vs. 8.4%; P <0.001), HECSI-75 (49.4% vs. 20.9%; P <0.001), HECSI-90 (30.3% vs. 10.6%; P <0.001), and DLQI ≥4-point improvement (73.3% vs. 47.8%; P <0.001). Most frequent adverse events (occurring in ≥5% of patients) were COVID-19, nasopharyngitis, and headache with similar rates in both treatment groups. Conclusions In the DELTA-1 and -2 pooled analysis, delgocitinib cream twice-daily confirmed its clinical efficacy in patient- and clinician-reported efficacy outcomes versus cream vehicle in adult CHE patients and suggests an innovative treatment option in this often difficult-to-treat patient population.

Background Amlitelimab is a fully-human, non-depleting, anti-OX40 ligand (OX40L) monoclonal antibody that binds to OX40L on antigen-presenting cells. Amlitelimab blocks the interaction of OX40L with OX40 on activated T-cells, inhibiting T-cell dependent inflammation without depleting T-cells. Objective To evaluate the efficacy and safety of amlitelimab (Part 1), and explore the maintenance of clinical response over a 28-Week period (Part 2) in patients with moderate-to-severe AD. Methods STREAM-AD (NCT05131477), was a randomized, double-blind, placebo-controlled Phase 2b trial, that included a 24-Week, double-blind, treatment period (Part 1), a 28-Week maintenance/withdrawal period (Part 2), and a 16-Week safety follow-up. In Part 1, adult participants were randomized 1:1:1:1:1 to subcutaneous amlitelimab Q4W (250mg with 500mg loading dose [+ LD], n=77; 250mg, n=78; 125mg, n=77; 62.5mg, n=79) or placebo Q4W (n=79). In Part 2, Clinical responders (defined as those achieving EASI-75 and/or IGA 0/1 at Week-24) in Part 1, were rerandomized 3:1 to withdraw or continue pre-Week 24 Q4W dose (250mg + LD, n=34 [withdrawal]/n=13 [continuing]; 250mg, n=28/n=12; 125mg, n=33/n=12; 62.5mg, n=35/n=7; placebo responders continuing placebo, n=16), and were followed to Week-52 to evaluate maintenance of clinical response. Primary efficacy endpoint was percent change in EASI from baseline at Week-16. Key secondary endpoints were proportion of patients achieving IGA 0/1, EASI-75, PP-RNS≥4. The statistical analysis was performed using two methods: 1) imputing the endpoint as nonresponder after rescue medication use (NRI); and 2) including all measurements regardless of rescue use (treatment policy). Results Out of 390 participants enrolled in Part 1, 190 entered Part 2. In Part 1, all four doses of amlitelimab demonstrated statistically significant improvements in percent change in EASI from baseline to Week-16 vs placebo; the highest response was seen with 250mg + LD group. Clinically meaningful improvements in key secondary endpoints were observed at Week-16, with continued improvements through Week-24. In Part 2, maintenance of EASI-75 and/or IGA 0/1 response at Week-52 was observed in 59%, 63%, 55%, and 66% of clinical responders withdrawn from 250mg + LD, 250mg, 125mg, and 62.5mg, respectively (NRI). Using treatment policy, 77%, 82%, 67%, and 74% maintained response off-drug, respectively. Those continuing amlitelimab treatment had numerically higher maintenance response rates. AD-related biomarkers were reduced during Part 1 and remained decreased over Part 2. Amlitelimab was well tolerated across all dose groups, with no new safety concerns identified during the 52-Weeks. Conclusion Clinically meaningful efficacy with amlitelimab was demonstrated over 52-Weeks, with an acceptable safety profile. Clinical responses were maintained in most patients 28-Weeks after treatment discontinuation. [ABSTRACT FROM AUTHOR]

Introduction/Background In patients with moderate to severe Chronic Hand Eczema (CHE), delgocitinib cream, a topical pan-Janus kinase inhibitor, was well tolerated and demonstrated significant improvement in all efficacy endpoints in DELTA-1 and -2. Objectives The objectives of this study were to evaluate the long-term safety and efficacy of twice-daily applications of delgocitinib cream 20 mg/g as needed for up to 36 weeks in adults with CHE in the Phase 3 open-label DELTA-3 trial (NCT04949841), an extension trial of the 16-week DELTA-1 (NCT04871711) and DELTA-2 (NCT04872101) trials. Methods In DELTA-3, subjects who completed the 16-week (W) treatment period in DELTA-1 and DELTA-2 were treated on an as-needed basis with twice-daily delgocitinib cream 20 mg/g for 36 weeks (n=801). Subjects with Investigator's Global Assessment for CHE (IGA-CHE) ≥2 received delgocitinib cream until symptoms resolved (i.e. IGA-CHE 0/1 [clear/almost clear]). Primary endpoint was number of treatment-emergent adverse events (TEAEs). Key secondary endpoints were IGA-CHE 0/1 and ≥75%/≥90% improvement in Hand Eczema Severity Index (HECSI-75/90) scores; Hand Eczema Symptom eDiary captured patient-reported worst severity of itch/pain over the past 24 hours. Results No safety concerns were identified during delgocitinib cream treatment in DELTA-1 (n=325; R=305.4; PYO=100.9), DELTA-2 (n=313; R=280.6; PYO=95.9) and DELTA-3 (n=801; R=231.1; PYO=535.7). In DELTA-3, the most frequent TEAEs were COVID-19 and nasopharyngitis. In DELTA-3, IGA-CHE 0/1, HECSI-75, HECSI-90 and ≥4-point itch/pain reduction were maintained from baseline (24.6%, 51.8%, 31.8%, and 50.6%/51.9%, respectively) to W36 (30.0%, 58.6%, 36.6%, and 52.4%/55.4%, respectively) among delgocitinib cream-treated subjects in the parent trials. Among those treated with cream vehicle in parent trials, response rates improved from baseline (9.1%, 23.7%, 12.0%, and 26.3%/32.3%, respectively) to W36 (29.5%, 51.5%, 35.7%, and 41.3%/43.3%, respectively). Conclusions Overall, with delgocitinib cream 20 mg/g treatment no safety concerns were identified and efficacy further improved, supporting the benefit of long-term as-needed use of delgocitinib cream in patients with moderate to severe CHE.

Introduction/Background Itch and pain are two of the most common and burdensome symptoms of Chronic Hand Eczema. Delgocitinib cream, a topical pan-Janus kinase inhibitor, was well tolerated and demonstrated significant improvement in primary and all secondary efficacy endpoints in DELTA-1 (NCT04871711) and DELTA-2 (NCT04872101). Objectives The objectives of this analysis were to assess the effect on itch and pain of twice-daily applications of delgocitinib cream 20 mg/g, including early onset of reductions, compared with cream vehicle in the treatment of adults with moderate to severe CHE in a pooled analysis of the pivotal Phase 3 DELTA-1 and DELTA-2 trials. Methods This analysis includes pooled data from DELTA-1 and -2 (delgocitinib cream 20 mg/g [n=639]; cream vehicle [n=321]; twice-daily). The Hand Eczema Symptom eDiary (HESD) captured patient-reported worst severity of itch and pain over the past 24 hours on an 11-point numeric rating scale (0=no itch/pain to 10=severe itch/pain). Changes in itch and pain from baseline were assessed daily during Week (W)1 and weekly from W1-16. Results For itch, a significant least square (LS) mean reduction from baseline was detected 1 day after patients first applied delgocitinib 20 mg/g (0.75) versus the cream vehicle group (0.32, P<0.001). For pain, a significant LS mean reduction was detected 3 days after the first application of delgocitinib cream (0.98) versus cream vehicle (0.58, P<0.001). The LS mean itch and pain reductions continued for delgocitinib cream-treated patients up to W16 (P<0.001). A clinically meaningful ≥4-point reduction in itch was achieved by significantly more patients applying delgocitinib cream from W2 (14.2%) versus cream vehicle (6.3%, P<0.001) and onwards to W16 (delgocitinib cream: 47.2%; cream vehicle: 21.5%; P<0.001). Similar results for a ≥4-point reduction in pain were observed. Conclusions Early onset of itch and pain reduction was observed within W1 for delgocitinib-treated patients, with reductions remaining significantly greater versus cream vehicle-treated patients from W1 to W16.

Background: Drugs are a frequent cause of severe anaphylactic reactions. Here, we analyze a large dataset on drug induced anaphylaxis regarding elicitors, risk factors, symptoms, and treatment. Methods: Data from the European Anaphylaxis Registry (2007–2019) with 1815 reported cases of drug‐induced anaphylaxis were studied accordingly. Results: Drugs are the third most frequent cause of anaphylaxis reported in the Anaphylaxis Registry. Among the eliciting groups of drugs analgesics and antibiotics were far most often reported. Female and senior patients were more frequently affected, while the number of children with DIA was low. DIA patients had symptoms affecting the skin and mucous membranes (n = 1525, 84.02%), the respiratory (n = 1300, 71.63%), the cardiovascular (n = 1251, 68.93%) and the gastrointestinal system (n = 549, 30.25%). Drugs caused significant more severe reactions, occurred more often in medical facilities and led to increased hospitalization rates in comparison to food and insect venom induced anaphylaxis. Adrenaline was used more often in patients with DIA than in anaphylaxis due to other causes. Patients with skin symptoms received more antihistamines and corticosteroids in the acute treatment, while gastrointestinal symptoms led to less adrenaline use. Conclusion: The study contributes to a better understanding of DIA, with a large number of cases from Europe supporting previous data, e.g., analgesics and antibiotics being the most frequent culprits for DIA. Female gender and higher age are relevant risk factors and despite clear recommendations, the emergency treatment of DIA is not administered according to the guidelines. [ABSTRACT FROM AUTHOR]
