PHASE1

Imetelstat Combinations in Relapsed AML

Sponsor: Douglas Tremblay

View on ClinicalTrials.gov

Summary

IMAGINE is a two-part trial to evaluate the safety and preliminary efficacy of imetelstat in combination with azacitidine with or without venetoclax in patients with relapsed or refractory AML. The trial will consist of a safety run-in phase (Part A) employing a 3+3 design to monitor dose-limiting toxicities of imetelstat when administered in combination with a fixed dose of azacitidine. Part B will consist of a phase 1b trial employing a BOIN12 design to determine the optimal biological dose of imetelstat, starting at a lower dose level, in combination with azacitidine and venetoclax. Total of up to 36 participants will be accrued over 54 months at Mount Sinai Hospital. Estimated duration of trial is 114 months including recruitment, screening, treatment, and follow-up.

Interventions

DRUG

Imetelstat

Three 3 dose levels administered on Day 1 of each 28-day cycle for Safety Run-in Phase and optimal dose to be administered on Day 1 of each 28-day cycle

DRUG

Azacitidine

75mg/m2 IV or subcutaneous (SQ) once daily for Days 1 (+/- 1 day) through 7 (+/- 1 day) of each 28-day cycle. Azacitidine can be administered locally as long as documentation of administration is provided to the study team.

DRUG

Venetoclax

Venetoclax 400mg oral once daily for Days 1 (+/- 1 day) through 14 (+/- 1 day) of each 28-day cycle. Venetoclax reduced dosey should be substituted if concomitant posaconazole, or if other concomitant strong CYP3A4 inhibitor (e.g. voriconazole) or 200mg for moderate CYP3A4 inhibitor (e.g. isavuconazole). For Cycle 1, participants will receive a venetoclax ramp-up dose on day 1, day 2, and days 3-14 of venetoclax,. If the participant is being treated with concomitant posaconazole, or other concomitant strong CYP3A4 inhibitor, or with a concomitant moderate CYP3A4 inhibitor or a pg-p inhibitor, participants will receive a lower ramp-up dose on day 1, day 2, and days 3-14 of venetoclax.
