Percentage (%) of Participants Who Achieved Greater Than or Equal (>=) to 75% Improvement From Baseline in Psoriasis Area Severity Index (PASI) Score at Week 12
Baseline and Week 12

The Psoriasis area severity index (PASI) is a standard tool for assessing the severity of psoriasis that considers the overall severity of erythema, induration, and scaling (each scored separately), and the extent of body surface area (BSA) affected with psoriasis. The 3 clinical signs are each graded on a 5-point scale (0=none to 4=severe) and the percent BSA affected is scored on a 7-point scale (0= 0% skin with psoriasis to 6= ≥ 90% skin with psoriasis). The individual scores are multiplied by a weighted factor for each body region; the sum of these scores gives the overall PASI score. The PASI is a composite scoring assessed by the investigator for the severity of lesions and the area affected into a single score with a range of 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. Note: The 95% credible interval (CrI) was reported as a method of dispersion.

Frequently asked questions about GSK2982772

What is GSK2982772 used for?

GSK2982772 is an investigational small molecule being developed for autoimmune diseases, including psoriasis, ulcerative colitis, inflammatory bowel diseases, and rheumatoid arthritis. It has been studied in Phase 2 clinical trials for moderate to severe rheumatoid arthritis and ulcerative colitis, though it remains investigational and is not approved.

How does GSK2982772 work?

GSK2982772 is a small molecule that targets RIPK1, a kinase involved in necroptosis and inflammatory signaling. By inhibiting RIPK1, it aims to reduce inflammation and tissue damage in autoimmune and inflammatory conditions. This mechanism is being evaluated in clinical trials for diseases like rheumatoid arthritis and ulcerative colitis.

Who is developing GSK2982772?
