Trial Outcomes & Findings for A Study of GSK2981278 Ointment in Subjects With Plaque Psoriasis (NCT NCT03004846)

NCT ID: NCT03004846

Last Updated: 2019-04-18

Results Overview

An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability, is a congenital anomaly/ birth effect, other situations and is associated with liver injury or impaired liver function. The analysis was performed on Safety analysis Population which comprised of all participants exposed to at least 1 application of study medication.

Participant Flow

Participants with chronic stable plaque psoriasis were recruited in this 2 part study to evaluate safety, tolerability and clinical effect of GSK2981278.

A total of 10 participants were screened; of which two were screen failures and eight were included in the treatment phase of Part A and received GSK2981278 4% ointment for 8 weeks. Part B of this study was not conducted as pre-defined efficacy criteria for continuing to Part B were not met. Hence no participants were enrolled in Part B.

The investigator assessed application site tolerability focusing on the treated non-lesional skin surrounding the plaques at each visit using the 5-point tolerability assessment scale ranging from 0 (no intolerance) to 4 (very severe intolerance). Number of participants in the corresponding score at Day 1, 15, 29 and 57 has been presented.

The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. Urine samples were collected from participants and urine pH levels were assessed at Baseline, Day 15, Day 29 and Day 57. Last observation values collected prior to the first application of study treatment were considered as Baseline values. Change from Baseline was calculated as post-Baseline visit values minus Baseline value.

The 5-point scale ranges from 0=clear to 4=severe. Last observation values collected prior to the first application of study treatment were considered as Baseline values. Change from Baseline was calculated as by subtracting post-Baseline visit values minus Baseline value.

The PASI is a standard tool for assessing the severity of psoriasis that considers the overall severity of erythema, thickness, and scale, 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. Higher scores indicate more severe disease. Last observation values collected were considered as Baseline values. Change from Baseline was calculated as post-Baseline visit values minus Baseline value.
