Robust Pipeline of 50+ Therapies Reshaping Moderate to Severe Atopic Dermatitis Treatment Landscape
• The moderate to severe atopic dermatitis market is experiencing significant growth with 45+ companies developing over 50 pipeline therapies, driven by rising global prevalence and increased awareness of the condition.
• Recent advancements include promising biologics like rezpegaldesleukin (granted FDA fast-track designation), JAK inhibitors such as VC005 and QY201, and novel mechanisms targeting IL-4/IL-13 pathways, offering new hope for patients with inadequate response to current treatments.
• Key players including Nektar Therapeutics, Corvus Pharmaceuticals, and Apogee Therapeutics are advancing clinical trials with significant milestones expected in late 2025, potentially transforming the therapeutic landscape for this chronic inflammatory skin condition.
Nektar and TrialNet Partner to Test Novel T-Cell Therapy Rezpegaldesleukin in Early-Stage Type 1 Diabetes
• Nektar Therapeutics and TrialNet have announced a collaboration to evaluate rezpegaldesleukin, a first-in-class T regulatory cell stimulator, in patients with new-onset type 1 diabetes.
• The Phase 2 randomized trial will enroll approximately 70 adults and children, measuring C-peptide preservation over 12 months to assess the drug's potential to slow disease progression.
• Rezpegaldesleukin works by expanding regulatory T cells to restore immune balance, targeting the underlying autoimmune mechanism of type 1 diabetes.
Eirion Therapeutics' ET-02 Shows Promise in Phase 1 Trial for Androgenic Alopecia
• Eirion Therapeutics announced positive results from its first-in-man clinical trial of topical ET-02 for androgenic alopecia.
• The Phase 1 trial demonstrated that ET-02 was safe and well-tolerated among participants.
• Early results indicated that improvements were observed as early as 5 weeks into the treatment.
• The 5% dosage of ET-02 showed a significant increase in non-vellus hair count, marking a potential breakthrough in hair loss treatment.
Nektar's Rezpegaldesleukin Receives FDA Fast Track for Atopic Dermatitis Treatment
• The FDA has granted Fast Track designation to rezpegaldesleukin for moderate-to-severe atopic dermatitis in patients 12 years and older.
• Rezpegaldesleukin targets the interleukin-2 receptor complex, stimulating regulatory T cell proliferation to restore immune balance.
• Phase 2b REZOLVE-AD study has completed enrollment, with topline data expected in Q2 2025, evaluating EASI score improvements.
• Fast Track designation allows for more frequent interactions with the FDA, potentially accelerating the drug's development and approval.
FDA Anticipated to Decide on Dupixent, Pz-cel, and Roflumilast Foam for Dermatologic Conditions by Mid-2025
• The FDA is reviewing Dupixent for chronic spontaneous urticaria, with a PDUFA date of April 18, 2025, potentially offering a novel targeted therapy after a decade of limited options.
• Abeona Therapeutics' pz-cel for recessive dystrophic epidermolysis bullosa has a resubmitted BLA with a PDUFA date of April 29, 2025, following a Complete Response Letter earlier in 2024.
• Arcutis Biotherapeutics' roflumilast foam for scalp and body psoriasis has a PDUFA date of May 22, 2025, offering a steroid-free alternative for hard-to-treat areas.
Nuvation Bio's Taletrectinib Gains FDA Priority Review and Expanded Access Program for ROS1+ NSCLC
• The FDA granted priority review to Nuvation Bio's NDA for taletrectinib, a next-generation ROS1 inhibitor, for advanced ROS1+ non-small cell lung cancer, setting a PDUFA date of June 23, 2025.
• Taletrectinib demonstrated promising efficacy and tolerability in the TRUST-I and TRUST-II trials, showing durable responses and prolonged progression-free survival in ROS1+ NSCLC patients.
• Nuvation Bio has initiated an Expanded Access Program (EAP) in the U.S. for taletrectinib, offering access to eligible patients with advanced ROS1+ NSCLC outside of clinical trials.
• The NDA is based on pooled data from the TRUST-I and TRUST-II studies, which included over 300 patients, representing the largest ROS1-positive NSCLC dataset supporting an NDA.
Rezpegaldesleukin Shows Promise in Inflammatory Skin Diseases
• Phase 1b trials of rezpegaldesleukin in atopic dermatitis and psoriasis demonstrate durable, dose-dependent improvements in disease activity.
• Biomarker analysis suggests rezpegaldesleukin modulates multiple Treg-mediated pathways, impacting tissue-resident memory T cells.
• Clinical improvements in atopic dermatitis patients were marked by an 83% improvement in EASI score after 12 weeks of treatment.
• Nektar Therapeutics plans to report topline data from Phase 2b studies in atopic dermatitis and alopecia areata next year.
Rezpegaldesleukin Shows Promise in Treating Atopic Dermatitis and Psoriasis
• Phase 1b studies reveal rezpegaldesleukin's efficacy, safety, and tolerability in patients with atopic dermatitis and psoriasis.
• The drug dose-dependently increased regulatory T cells and improved disease outcomes, with effects lasting at least 36 weeks post-treatment.
• Biomarker analysis indicates rezpegaldesleukin modulates multiple immunoregulatory pathways, potentially attenuating Th1, Th2, and Th17 responses.
• Phase 2b studies in atopic dermatitis and alopecia areata are anticipated to release topline data next year.
