RCT: Zasocitinib Achieves Significant Psoriasis Improvement in Moderate to Severe Plaque Psoriasis

6 Sep, 2024 | 22:48h | UTC

Study Design and Population: This phase 2b, double-blind, placebo-controlled trial evaluated the efficacy, safety, and tolerability of zasocitinib, a selective tyrosine kinase 2 (TYK2) inhibitor, in patients with moderate to severe plaque psoriasis. Conducted across 55 centers in the US and Canada, the study enrolled 287 patients aged 18 to 70 years with a Psoriasis Area and Severity Index (PASI) score ≥12, and ≥10% of body surface area affected. Patients were randomized to receive zasocitinib at doses of 2 mg, 5 mg, 15 mg, or 30 mg, or a placebo, over 12 weeks.

Main Findings: At week 12, significant improvements in PASI were observed across all doses of zasocitinib. The primary endpoint of PASI 75 was achieved in 18%, 44%, 68%, and 67% of patients in the 2 mg, 5 mg, 15 mg, and 30 mg zasocitinib groups, respectively, compared to 6% in the placebo group. Higher PASI 90 and PASI 100 responses were also observed, particularly in the 15 mg and 30 mg groups. Adverse events were mild to moderate and occurred in 53% to 62% of patients receiving zasocitinib, compared to 44% for placebo.

Implications for Practice: Zasocitinib shows promise as an effective and well-tolerated oral treatment for moderate to severe plaque psoriasis. Its efficacy in achieving skin clearance (PASI 75 and above) at higher doses suggests potential for broader clinical use, with phase 3 trials warranted for further validation.

Network Meta-Analysis: Potent Corticosteroids, JAK Inhibitors, and Tacrolimus 0.1% Among the Most Effective Topical Treatments for Eczema – Cochrane Library

25 Aug, 2024 | 12:03h | UTC

Study Design and Population: This network meta-analysis included 291 randomized controlled trials involving 45,846 participants with varying eczema severity. The trials primarily focused on adults in high-income countries and assessed various topical anti-inflammatory treatments over a median duration of 21 to 28 days. The study aimed to compare the efficacy and safety of these treatments.

Main Findings: Potent topical corticosteroids (TCS), JAK inhibitors, and tacrolimus 0.1% were consistently ranked as the most effective treatments for reducing eczema symptoms and signs. In contrast, phosphodiesterase-4 (PDE-4) inhibitors like crisaborole 2% and mild TCS were among the least effective. Notably, tacrolimus, pimecrolimus, and crisaborole were more likely to cause local adverse effects such as burning and stinging, while short-term TCS use did not show an increased risk of skin thinning, although long-term use did.

Implications for Practice: The findings suggest that potent TCS, JAK inhibitors, and tacrolimus 0.1% are effective for short-term eczema control. However, given the risk of skin thinning with long-term TCS use and potential adverse effects with certain treatments, clinicians should consider patient preferences, treatment availability, and cost when selecting therapies.

RCT: Nemolizumab Plus Topical Therapy Improves Skin Clearance, Itch, and Sleep in Moderate-to-Severe Atopic Dermatitis – The Lancet

11 Aug, 2024 | 12:58h | UTC

Study Design and Population: This study reports on two identical 48-week, double-blind, randomized, placebo-controlled phase 3 trials (ARCADIA 1 and ARCADIA 2) involving 1,728 adolescents and adults with moderate-to-severe atopic dermatitis and pruritus unresponsive to topical corticosteroids. Participants were randomized 2:1 to receive nemolizumab (an IL-31 receptor antagonist) or placebo, alongside background topical corticosteroids (TCS) and/or calcineurin inhibitors (TCI).

Main Findings: At week 16, nemolizumab significantly improved primary outcomes compared to placebo, with a higher proportion achieving clear or almost clear skin (IGA success) and a 75% improvement in Eczema Area and Severity Index (EASI-75). Nemolizumab also showed significant early and sustained improvements in itch and sleep. The safety profile was comparable between groups, with treatment-emergent adverse events occurring in about half of the participants.

Implications for Practice: Nemolizumab, in combination with TCS-TCI, demonstrated robust efficacy in reducing inflammation, itch, and sleep disturbances in moderate-to-severe atopic dermatitis. If approved, it could provide an important addition to current treatment options, particularly for patients inadequately managed by existing therapies.

RCT: Oral and topical minoxidil equally effective for male hair loss treatment – JAMA Dermatol

7 May, 2024 | 15:26h | UTC

This study examines the effectiveness, safety, and tolerability of oral minoxidil compared to topical minoxidil in treating male androgenetic alopecia. Conducted as a double-blind, placebo-controlled randomized clinical trial, 90 men aged 18 to 55 with varying degrees of hair loss were recruited and followed for 24 weeks. Participants were divided into two groups: one receiving oral minoxidil 5 mg daily and the other using topical minoxidil 5% twice daily. The primary endpoint was the change in terminal hair density in both the frontal and vertex regions. Results showed that oral minoxidil did not outperform topical minoxidil in terms of increasing hair density on the frontal scalp, though it did show a slight superiority on the vertex area. Common side effects for the oral minoxidil group included hypertrichosis and headaches. Overall, oral minoxidil demonstrated similar efficacy to its topical counterpart and offers an alternative for patients preferring oral treatment or those intolerant to topical formulations.
