About

This is a prospective, single-arm, multi-center clinical trial to evaluate the efficacy and safety of selinexor combined with chidamide in the treatment of unfit R/R AML.

Full description

This protocol corresponds to a multicenter, open-label, single arm, prospective study designed to determine the efficacy and safety of selinexor in combination with chidamide for unfit R/R AML.

Selinexor will be given orally at 40 or 60mg on d1,4,8,11; Chidamide will be given orally at 10mg on d1-28; 28 days per cycle. patients can receive transplants at any time once they achieved complete remission and other patients will continue to receive treatment until disease progression or unacceptable toxic effects. After completion of study treatment, participants are followed up every 3 to 6 months for up to 2 years.

Study design allows 42 patients.

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Selinexor combined with chidamide

Experimental group

Description:

R/R AML who are ineligible for intensive chemotherapy will receive selinexor in combination with chidamide, 28 days per cycle, Selinexor will be used as 40 or 60mg BIW for two weeks, and chidamide will be used as 10mg/d from day 1 to 28. Depending on the level of recovery, patients will either be forced to come off study or have the option to continue the medication, receive maintenance therapy, or pursue an allogeneic stem cell transplant.
