GVHD, Chronic
Conditions
Brief summary
This is a phase 2, open-label, multicenter trial to evaluate the efficacy and safety of BN101 in subjects with Chronic Graft Versus Host Disease (cGVHD) after at least First Line of systemic therapy.
Detailed description
Approximately 30 subjects will be enrolled to receive orally administered BN101 200 mg QD (once daily) Study drug will be administered in 28-day cycles until disease progression or unacceptable toxicity. Subjects may receive study drug in the inpatient or outpatient setting. Curative Effect analysis The efficacy was analyzed based on MITT The point estimate and 95%CI of ORR were calculated based on the exact probability method of binomial distribution.If applicable, a logistic regression model will be used for multivariate analysis. Descriptive statistical analyses were provided for all secondary efficacy endpoints. The following subgroups will be analysed: * Severe cGVHD (Yes/No) * Number of organs involved (\<4 vs. ≥4) * Number of previous systemic cGVHD treatment (1 vs. ≥2) * Duration of cGVHD before inclusion (i.e., from the time of cGVHD diagnosis to the time of inclusion) * Lung Involvement (Yes/No)

|---|---|---|
| Time-to-Response (TTR) | 12 months | Time-to-response was measured as the time (in weeks) from first dose of study drug to the time of first documentation of response. Response was defined as the participants achieving a PR or CR at any post-baseline response assessment. Per the 2014 NIH Consensus Development Project for Clinical Trials in cGVHD criteria; CR was defined as the resolution of all manifestations in each organ or site and PR was defined as the improvement in at least 1 organ or site without progression in any other organ or site |
| Number of Participants With Best Response in Each Individual Organ | 12 months | Best response was defined as the percentage of participants with CR or PR. Response was assessed per the 2014 NIH Consensus Development Project for Clinical Trials in cGVHD criteria; CR was defined as the resolution of all manifestations in each organ or site; PR was defined as the improvement in at least 1 organ or site without progression in any other organ or site. Organ response assessment was performed on 9 individual organs: skin, eyes, mouth, esophagus, upper gastrointestinal (GI), lower GI, liver, lungs, and joints and fascia and is reported in this outcome measure. |
| Number of Participants With Change From Baseline in Overall Score on Lee cGvHD Symptom Scale at Specified Time Points | Baseline and 12 months | Lee cGVHD symptom scale, a patient-reported symptom scale used to measure symptom burden and 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 better outcome. Score for each subscale was normalized to a score ranged from 0 to 100, where higher score=worse symptoms. An overall Lee cGvHD score was calculated as average of these 7 subscales and it ranged from 0 to 100, where a higher score = worse symptoms. EOT visit was performed within 3 days after the participant's last dose of study drug. Baseline value was defined as valid and last non-missing value obtained within 28 days prior to participant receiving first study medication. |
| Failure-free Survival (FFS) | 12 months | Failure-free survival was defined as the time (in months) from first dose of study drug to either the start of another new systemic treatment for cGVHD, relapse of the underlying disease or death. If no such events happened, FFS was censored by last response assessment or long term follow up assessment, whichever was the latest and available. Kaplan-Meier survival method was used for the analysis. |
| Time to Next Therapy (TTNT) | 12months | The TTNT was defined as the time (in months) from first treatment to the time of new systemic cGVHD treatment. TTNT was censored by last response assessment or long term follow up assessment, whichever was earlier. Kaplan-Meier survival method was used for the analysis. |

EOT visit was performed within 7 days after the participant's last dose of study drug. Baseline value was defined as valid and last non-missing value obtained within 28 days prior to participant receiving first study medication. |
| Change From Baseline in in Global Severity Rating (GSR) Score by Clinician-reported cGVHD Assessment | 12months | The GSR assessment was performed by asking the participants to rate their disease severity of cGVHD symptoms on a 0 to 10-point numeric rating scale, where score 0 indicated 'not at all severe cGVHD symptoms' and score 10 indicated 'most severe cGVHD symptoms possible'. The response was defined using scores from 9 organs: skin, eyes, mouth, esophagus, upper gastrointestinal (GI) track, lower GI tract, liver, lungs, and joints and fascia plus GSR. End of treatment (EOT) visit was performed within 7 days after participant's last dose of study drug. Baseline value was defined as valid and last non-missing value obtained within 28 days prior to participant receiving first study medication. Change from Baseline was calculated as GSR score at Baseline minus the lowest GSR score on scheduled visits with possible ranges from -10 to 10. The higher the number means the better improvement in cGVHD symptoms. Only those categories in which at least 1 participant had data were reported. |
| Change From Baseline in Symptom Activity by cGVHD Activity Assessment Participant Self-Report | 12months | cGVHD symptom severity was self-reported by participants. Participants were asked to rate their disease symptom severity over the last week on the following questions: skin itching at its worst, moth dryness at its worst, mouth pain at its worst, mouth sensitivity at its worst, main compliant on eyes, symptom severity on eyes. Severity rating was done on a 0 to 10-point numeric rating scare, where score 0 indicated 'not at all severe cGVHD symptoms' and score 10 indicated 'most severe cGVHD symptoms possible'. EOT visit was performed within 7 days after participant's last dose of study drug. Baseline value was defined as valid and last non-missing value obtained within 28 days prior to participant receiving first study medication. Change from Baseline was calculated as the symptom severity score at Baseline minus the lowest symptom severity score on scheduled visits minuswith possible ranges from -10 to 10. The higher the number means the better improvement in cGVHD symptoms. |
| Overall Survival (OS) | 12months | Overall survival was defined as the time (in months) from first dose of study drug to the death due to any reason. If there was no death, OS was censored by last visit, last long-term follow-up, or study cut-off date, whichever occurred first. Kaplan-Meier survival method was used for the analysis. |
