According to the Krueger criteria, improvement score is classified as Good improvement defined as reduction in epidermal thickness by at least 30% normalized keratinocyte differentiation but most keratinocytes still express K16. Excellent improvement defined as reduction in epidermal thickness to normal or almost normal normalized keratinocyte differentiation and absent keratinocyte expression of K16. No improvement defined as no improvement in epidermal thickness keratinocyte differentiation or K16 expression on keratinocytes.

Number of participants with good or excellent improvement score are presented.
An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse or misuse. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant. The AE category in the data table includes participants who experienced serious or non-serious adverse events or both.

SRT2104 is an investigational small molecule being studied for several conditions, including sepsis, psoriasis, muscular atrophy, chronic obstructive pulmonary disease, type 2 diabetes, and ulcerative colitis. It has been evaluated in clinical trials for these indications, though it remains in early-stage development and is not approved for any use.
SRT2104 is a small molecule that activates sirtuin proteins, which are involved in cellular regulation and metabolism. By targeting these proteins, it is thought to influence inflammatory and metabolic pathways relevant to conditions like psoriasis, ulcerative colitis, and type 2 diabetes. This mechanism is under investigation in clinical trials.
SRT2104 is being developed by GSK plc, a global pharmaceutical company listed on the stock exchange under the ticker GSK. GSK has sponsored clinical trials to assess the drug's safety, tolerability, and efficacy across multiple disease areas, including metabolic and inflammatory conditions.
SRT2104 is in Phase 1 and Phase 2 clinical development. It has completed Phase 1 trials in healthy volunteers and patients with ulcerative colitis, as well as a Phase 2 trial in psoriasis. All seven trials are completed, and the drug remains investigational, with no FDA approval.
SRT2104 has been studied in seven completed clinical trials, including NCT00933062 in healthy male volunteers with type 2 diabetes, NCT00964340 in healthy elderly subjects with muscular atrophy, NCT01154101 in patients with moderate to severe psoriasis, and NCT01453491 in patients with ulcerative colitis. All trials are completed.
SRT2104 is the primary name used in clinical trials and scientific literature. No alternative names have been reported for this drug. It is consistently referred to as SRT2104 across all registered studies and publications.
