👶 FDA accepts sNDA for roflumilast cream in ages 2–5 [7] [17 Nov 2025]

https://www.dermatologytimes.com/view/roflumilast-snda-accepted-for-plaque-psoriasis-in-patients-2-to-5-years

Context: Arcutis seeks to extend ZORYVE cream 0.3% to ages 2–5; PDUFA 29 Jun 2026.

Key point: Supported by pediatric MUSE and long-term open-label data showing acceptable exposure and safety.

Implication: May influence prescriber choice and payer reviews pending full data.

✋ Tralokinumab ADHAND 32-week topline remains positive [8] [17 Nov 2025]

https://via.ritzau.dk/pressemeddelelse/14679407/leo-pharma-announces-positive-topline-32-week-key-results-in-adhand-trial?publisherId=12353927&lang=da

Context: Phase 3b, adults with moderate-to-severe hand involvement in AD; 16-week DB then 16-week open-label.

Key point: Week 16 primary and key secondary endpoints met, Week 32 endpoints also positive, no new safety issues noted.

Implication: May influence prescriber choice and payer reviews pending full data.

Why it matters

  • Biologics are differentiating on structural outcomes in PsA, a prescriber and payer priority.
  • Operational advances, like liquid infliximab, can deliver workflow and budget gains beyond efficacy.
  • Topical and systemic options are expanding across ages and hard-to-treat areas, supporting adherence.
  • Early cytokine-pathway targeting with steroid minimization is shaping pediatric rheumatology standards.
  • NK-cell strategies are moving into community autoimmune care, broadening delivery models.

FAQ

What is new in TREMFYA’s PsA dataset?

J&J reports sustained radiographic progression inhibition to Week 48 in APEX, with increasing ACR50 and no new safety signals, supporting an sBLA for structural-damage language [1].

How do the systemic JIA recommendations guide therapy?

Experts favor early IL-1 or IL-6 inhibition for key phenotypes, with short, tapered glucocorticoids to minimize exposure and clear escalation strategies [2].

What did Artiva show with AlloNK in autoimmune disease?

Initial data indicate outpatient feasibility, no CRS/ICANS, and deep B-cell depletion by Day 13 across analyzed samples, with FDA discussions for an RA pivotal design planned in 1H 2026 [3].

What changed for infliximab in the EU?

Celltrion’s Remsima IV liquid is EC-approved for all infliximab indications, eliminating reconstitution and reporting shorter prep time and lower prep costs vs powder [6].

Which Arcutis programs moved forward?

FDA accepted the sNDA for ZORYVE cream 0.3% in ages 2–5 with a 29 Jun 2026 PDUFA date [7], and Health Canada approved ZORYVE foam 0.3% for scalp and body psoriasis in patients 12+ [9].
