Trial Outcomes & Findings for Rimegepant in Moderate Plaque-type Psoriasis (NCT NCT04629950)

NCT ID: NCT04629950

Last Updated: 2025-07-17

Results Overview

Total score of Psoriasis Area and Severity Index ranges from 0 to 72. Change = (Week 16 score - Baseline score) for the placebo-controlled phase and (Week 15 score-Visit 12 score) for the extension phase. A low score means less severe disease while a high score reflects more severe disease. A score of 0 means no psoriasis. A PASI score of 5 to 10 is considered moderate disease and a score over 10 is considered severe. A score over 40 is rare. The primary outcome measure is the mean percent change in PASI score from baseline to week 16 in the placebo-controlled phase. For the extension phase, it is particularly interesting if a change is noted in the group that received placebo prior to the extension phase.

Participant Flow

Participants were recruited from the dermatology practices of the Weill Cornell Medical College Department of Dermatology and the practice of Neil Sadick, M.D., a voluntary faculty member of the department.

Ninety-six subjects were screened, 41 met criteria for entry. Five subjects withdrew or were withdrawn before being assigned to a group.

PRIMARY outcome

Timeframe: Baseline and Week 16 for placebo controlled trial. For Extension Phase, Visit 11/12 (Day 1) to Visit 15 (Week 12).

Population: The number of subjects in each arm of the extension phase of our study are a subset of the subjects treated in the double blind, placebo controlled initial phase of the study. Furthermore, one subject assigned to the placebo group was not included in the analysis due to having an adverse reaction (very severe insect bite reaction) prior to the first scheduled evaluation. Thus, the total number of analyzed subjects in the placebo-controlled phase was 35.

Total score of Psoriasis Area and Severity Index ranges from 0 to 72. Change = (Week 16 score - Baseline score) for the placebo-controlled phase and (Week 15 score-Visit 12 score) for the extension phase. A low score means less severe disease while a high score reflects more severe disease. A score of 0 means no psoriasis. A PASI score of 5 to 10 is considered moderate disease and a score over 10 is considered severe. A score over 40 is rare. The primary outcome measure is the mean percent change in PASI score from baseline to week 16 in the placebo-controlled phase. For the extension phase, it is particularly interesting if a change is noted in the group that received placebo prior to the extension phase.

Population: The number of subjects in each arm of the extension phase of our study are a subset of the subjects treated in the double blind, placebo controlled initial phase of the study. Furthermore, one subject assigned to the placebo group was not included in the analysis due to having an adverse reaction (very severe insect bite reaction) prior to the first scheduled evaluation. Thus, the total number of analyzed subjects in the placebo-controlled phase was 35.

To record the number of subjects whose PASI Score Improves by at least 50% by week 16 (Week 16 average score - Baseline average score) for the placebo-controled phase and the change from Visit 12 (Day 1) to Visit 15 (Week 12) for the extension phase. PASI range is 0-72 although PASI must be at least 5 for entry into the study. A score of 0 means no psoriasis. A PASI score of 5 to 10 is considered moderate disease and a score over 10 is considered severe. A score over 40 is rare.

Furthermore, one subject assigned to the placebo group was not included in the analysis due to having an adverse reaction (very severe insect bite reaction) prior to the first scheduled evaluation. Thus, the total number of analyzed subjects in the placebo-controlled phase was 35.

Score of the Investigator's Global Assessment instrument ranges from 0 to 5. Three parameters (erythema, induration and scaling, each is scored on a scale of 0 to 5. Erythema: 0 to 5 is the scale of intensity of erythema with 5 being the highest. Induration: 0 to 5 reflects the degree of elevation of the lesion with 5 being the most elevated. Scaling: 0 to 5 is the abundance of scale as well as the thickness and tenacious character of the scale with 5 being the most abundant, thick and tenacious scale) were each measured and averaged to obtain a score averaged to the nearest integer. The change from baseline to week 16 for each subject was calculated for the placebo-controlled phase and the change from Visit 12 to Visit 15 for the extension phase and the mean difference +/- standard deviation between groups was compared. For the extension phase, it is particularly interesting if a change is noted in the group that received placebo prior to the extension phase.

SECONDARY outcome

Timeframe: Baseline and Week 16 for placebo controlled trial. For Extension Phase, Visit 11/12 (Day 1) to Week 12.

Population: The number of subjects in each arm of the extension phase of our study are a subset of the subjects treated in the double blind, placebo controlled initial phase of the study. Furthermore, one subject assigned to the placebo group was not included in the analysis due to having an adverse reaction (very severe insect bite reaction) prior to the first scheduled evaluation. Thus, the total number of analyzed subjects in the placebo-controlled phase was 35.

The Visual Analogue Scale ranges from 0 to 10. 0= no pruritus, \< 3= mild pruritus, ≥ 3-\<7= moderate pruritus, ≥ 7-\<9 = severe pruritus, ≥ 9= very severe pruritus. We separately measured the reduction in average itch over the preceding 3 days and the reduction in maximum itch over the previous 7 days for each subject. For the extension phase, it is particularly interesting if a change is noted in the group that received placebo prior to the extension phase.

Timeframe: Visit 11/12 (Day 1) to Visit 15 (Week 12).

Total score of Psoriasis Area and Severity Index ranges from 0 to 72. A low score means less severe disease while a high score reflects more severe disease. A score of 0 means no psoriasis. A PASI score of 5 to 10 is considered moderate disease and a score over 10 is considered severe. A score over 40 is rare. Change = (Week 15 score-Visit 12 score) for the extension phase was examined.

Scaling: 0 to 5 is the abundance of scale as well as the thickness and tenacious character of the scale with 5 being the most abundant, thick and tenacious scale) were each measured and averaged to obtain a score averaged to the nearest integer.

One subject was withdrawn from the placebo group between the baseline visit and visit 1 due to an adverse reaction to bug bites. Therefore, the subject received IP and would be at risk for an AE but was not included in the analysis as we did not collect visit 1 data. Thus, for purposes of adverse events all 18 subjects assigned to the placebo group were included in the adverse events tables while only 17 subjects were included in the placebo-controlled phase in the outcome measures data tables.
