Summary

The purpose of this study is to measure safety and efficacy of oral belumosudil in Black or African American male and female participants with cGVHD who have previously been treated with at least 2 prior lines of systemic therapy aged 12 years and above.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

• Participants are included in the study if any of the following criteria apply:

• Subject is Black or African American by self-identification.

• Previously received at least 2 and not more than 5 lines of systemic therapy for cGVHD.

• Receiving glucocorticoid therapy with a stable dose over the 2 weeks prior to screening.

• Have persistent cGVHD manifestations and systemic therapy is indicated.

• Karnofsky (if aged ≥ 16 years) / Lansky (if aged < 16 years) Performance Score of ≥ 60.

• At least 12 years of age; weight ≥ 40 kilograms (kg).

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x upper limit of normal (ULN).

• Total bilirubin ≤ 1.5 x ULN.

• Contraception (with double contraception methods) for male and female participants; not pregnant or breastfeeding for female participants

• Capable of giving signed informed consent.

Exclusion Criteria:

• Participants are excluded from the study if any of the following criteria apply:

• Subject has not been on a stable dose/regimen of systemic cGVHD treatment(s) for at least 2 weeks prior to screening. (Note: Concomitant corticosteroids, calcineurin inhibitors, sirolimus, MMF, methotrexate, rituximab, and ECP are acceptable. Systemic investigational GVHD treatments are not permitted).

• Histological relapse of the underlying cancer or post-transplant lymphoproliferative disease at the time of screening.

• Current treatment with ibrutinib or ruxolitinib. Prior treatment with ibrutinib or ruxolitinib is allowed with a washout of at least 28 days prior to enrollment.

• History or other evidence of severe illness or any other conditions that would make the subject, in the opinion of the Investigator, unsuitable for the study (such as malabsorption syndromes, poorly controlled psychiatric disease, or coronary artery disease).

• Corrected QT interval using Fridericia's formula (QTc[F]) > 480 ms.

• Forced expiratory volume (in the first second; FEV1) ≤ 39% The above information is not intended to contain all considerations relevant to the potential participation in a clinical trial.
