Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Dose limited toxicity (DLT) at each dose can assess the incidence of DLT in patients during the observation period of DLT (Part A only)
Time Frame: Starting from the first medication, observe for 31 days
Number of Participants With Adverse Event (AE), Serious Adverse Event, (SAE) and Laboratory Abnormalities Defined as Dose Limiting Toxicities (DLT);
Starting from the first medication, observe for 31 days
Overall response rate after 6 cycles of treatment
Time Frame: 6 months
Proportion of participants with CR or PR after 6 cycles of treatment as defined by the 2014 NIH Consensus Development Project on Criteria in cGVHD
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse Events
Time Frame: Through study completion, an average of 2 years
Safety assessments will be carried out during the trial.
Through study completion, an average of 2 years
