About

This phase I/II trial studies whether glasdegib is helpful in treating sclerosis associated with chronic graft-versus-host disease. It will also investigate the safety of glasdegib in treating patients with chronic graft-versus-host disease.

Full description

OUTLINE: This is a phase I/II study.

Patients receive glasdegib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

Enrollment: 15 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
