Trial Outcomes & Findings for Ibrutinib in Combination With Corticosteroids vs Placebo in Combination With Corticosteroids in Participants With New Onset Chronic Graft Versus Host Disease (cGVHD) (NCT NCT02959944)

NCT ID: NCT02959944

Last Updated: 2023-03-30

Results Overview

Response rate was defined as the percentage of participants who were responders. Responders were defined as participants who had a complete response (CR) or a partial response (PR) at 48 weeks without starting any subsequent therapy for cGVHD or having evidence of relapse of their underlying disease that was indication for transplant prior to response assessment at 48 weeks. Response was defined using the National Institutes of Health (NIH) Consensus Panel Chronic GVHD Activity Assessment (2014). Skin, mouth, liver, upper and lower gastrointestinal, esophagus, lung, eye, and joint/fascia are the organs or sites considered in evaluating overall response. CR is defined as resolution of all manifestations in each organ or site. PR is defined as improvement in at least 1 organ or site without progression in any other organ or site.

Participant milestones

Measure	Ibrutinib + Prednisone Ibrutinib (420 mg) given orally once daily continuously starting on Week 1 Day 1 until cGVHD progression, progression of underlying malignancy, participant begins another systemic treatment for cGVHD or unacceptable toxicity. The 420 mg dose was adjusted for cytochrome P450 \[CYP\] inhibitors or hepatic dysfunction as applicable. Prednisone 1 mg/kg/d given orally once daily continuously starting on Week 1 Day 1 until unacceptable toxicity or until participant is successfully tapered from the prednisone. Starting prednisone dose may be as low as 0.5 mg/kg/d if a participant cannot tolerate higher doses.	Placebo + Prednisone Placebo given orally once daily continuously starting on Week 1 Day 1 until cGVHD progression, progression of underlying malignancy, participant begins another systemic treatment for cGVHD or unacceptable toxicity. Prednisone 1 mg/kg/d given orally once daily continuously starting on Week 1 Day 1 until unacceptable toxicity or until participant is successfully tapered from the prednisone. Starting prednisone dose may be as low as 0.5 mg/kg/d if a participant cannot tolerate higher doses.

SECONDARY outcome

Timeframe: Assessed at Weeks 5, 13, 25, 37, 49, 30 days after the last dose of study drug, and then every 12 weeks of follow-up until progressed disease. (Cumulatively up to 30 March 2020)

Population: Intent to Treat Population: all randomized participants.

Clinically meaningful improvement on Lee cGVHD symptom scale was defined as at least a 7-point decrease in Lee Symptom Scale overall summary score on at least 2 consecutive visits, not preceded by progressive disease, relapse of underlying disease or start of subsequent cGVHD treatment.

The Lee cGVHD Symptom Scale score has 7 subscales (Skin, Eyes and Mouth, Breathing, Eating and Digestion, Muscles and Joints, Energy, and Mental and Emotional) with ratings as follows: 0- Not at all, 1- Slightly, 2 Moderately, 3 Quite a bit, 4-Extremely, with lower values representing a better outcome. A score is calculated for each subscale by taking the mean of all items completed if more than 50% were answered and normalizing to a 0 to 100 scale. An overall score is calculated as the average of these 7 subscales if at least 4 subscales have valid scores.

Primary Analysis: Percentage of Participants With Improvement in Overall Score on Lee cGVHD Symptom Scale at Two Consecutive Visits	38.9 percentage of participants	26.5 percentage of participants

SECONDARY outcome

Timeframe: Assessed at Weeks 5, 13, 25, 37, 49, 30 days after the last dose of study drug, and then every 12 weeks of follow-up until progressed disease. (Cumulatively up to 12 July 2021)

Population: Intent to Treat Population: all randomized participants.

Clinically meaningful improvement on Lee cGVHD symptom scale was defined as at least a 7-point decrease in Lee Symptom Scale overall summary score on at least 2 consecutive visits, not preceded by progressive disease, relapse of underlying disease or start of subsequent cGVHD treatment.

The Lee cGVHD Symptom Scale score has 7 subscales (Skin, Eyes and Mouth, Breathing, Eating and Digestion, Muscles and Joints, Energy, and Mental and Emotional) with ratings as follows: 0- Not at all, 1- Slightly, 2 Moderately, 3 Quite a bit, 4-Extremely, with lower values representing a better outcome. A score is calculated for each subscale by taking the mean of all items completed if more than 50% were answered and normalizing to a 0 to 100 scale. An overall score is calculated as the average of these 7 subscales if at least 4 subscales have valid scores.
