Study of ASTX727 vs IV Decitabine in MDS, CMML, and AML

Acute Myeloid Leukemia Clinical Trial

Official title: A Phase 3, Randomized, Open-Label, Crossover Study of ASTX727 (Cedazuridine and Decitabine Fixed-Dose Combination) Versus IV Decitabine in Subjects With Myelodysplastic Syndromes (MDS), Chronic Myelomonocytic Leukemia (CMML), and Acute Myeloid Leukemia (AML)

Status Completed

Clinical Trial Summary

Multicenter, randomized, open-label, crossover PK study of ASTX727 versus IV decitabine. Adult subjects who are candidates to receive IV decitabine will be randomized 1:1 to receive the ASTX727 tablet Daily×5 in Cycle 1 followed by IV decitabine 20 mg/m^2 Daily×5 in Cycle 2, or the converse order. After completion of PK studies during the first 2 treatment cycles, subjects will continue to receive treatment with ASTX727 from Cycle 3 onward (in 28-day cycles) until disease progression, unacceptable toxicity, or the subject discontinues treatment or withdraws from the study.

Clinical Trial Description

This Phase 3 study will establish PK equivalence of ASTX727 to IV decitabine in approximately 118 evaluable subjects. Eligible subjects will receive both study treatments: oral investigational drug ASTX727, and IV decitabine, as follows: subjects will be randomly assigned 1:1 to receive ASTX727 or IV decitabine in Cycle 1 and then cross over to the other therapy in Cycle 2.

In the ASTX727 cycle, subjects will receive the ASTX727 tablet Daily×5. Serial PK measurements (blood draws) will be done on Days 1, 2, and 5, along with pre-dose PK assessments on Days 1-5 and an assessment at 3 hours post dose on Day 3. Subjects will be required to fast from food for 4 hours on days when receiving ASTX727: at least 2 hours before and 2 hours after dosing.

In the IV decitabine cycle, subjects will receive a 1-hour infusion of IV decitabine 20 mg/m^2 Daily×5. Serial PK measurements will be done on Days 1 and 5, along with pre-dose and 1-hour post-infusion assessments on Day 3.

In Cycles ≥3, subjects will receive the ASTX727 tablet Daily×5 in 28-day cycles. (No PK assessments will be done from Cycle 3 onward.) ;
