A Study of Revumenib in R/R Leukemias Including Those With an MLL/KMT2A Gene Rearrangement or NPM1 Mutation

Официальное название

A Phase 1/2, Open-label, Dose-Escalation and Dose-Expansion Cohort Study of SNDX-5613 in Patients With Relapsed/Refractory Leukemias, Including Those Harboring an MLL/KMT2A Gene Rearrangement or Nucleophosmin 1 (NPM1) Mutation

Обзор

Phase 1 dose escalation will determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of revumenib in participants with acute leukemia. In Phase 2, participants will be enrolled in 4 indication-specific expansion cohorts to determine the efficacy, short- and long-term safety, and tolerability of revumenib.

Подробное описание

Phase 1: Oral revumenib; sequential cohorts of escalating dose levels of revumenib to identify the MTD and RP2D. Participants will be enrolled in one of six dose-escalation arms:

Arm A: Participants not receiving any strong cytochrome P450 3A4 (CYP3A4) inhibitor/inducers or fluconazole.

Arm B: Participants receiving itraconazole, ketoconazole, posaconazole, or voriconazole (strong CYP3A4 inhibitors) for antifungal prophylaxis.

Arm C: Participants receiving revumenib and cobicistat.

Arm D: Participants receiving fluconazole (moderate CYP3A4 inhibitor) for antifungal prophylaxis.

Arm E: Participants not receiving any weak, moderate, or strong CYP3A4 inhibitors/inducers.

Arm F: Participants receiving isavuconazole (moderate CYP3A4 inhibitor) for antifungal prophylaxis.

In Phase 2, participants will be enrolled in 4 indication-specific expansion cohorts to determine the efficacy, short- and long-term safety, and tolerability of revumenib:

* Cohort 2A: Participants with KMT2Ar acute lymphoblastic leukemia (ALL)/mixed phenotype acute leukemia (MPAL) * Cohort 2B: Participants with KMT2A AML * Cohort 2C: Participants with NPM1m AML * Cohort 2D: Participants with acute leukemia (including KMT2Ar, NPM1m, NUP98r and other acute leukemias expected to have HOX/MEIS upregulation)

Вмешательства

• Препарат revumenib
  revumenib orally
• Препарат cobicistat
  Phase 1 Arm C participants will receive 150 mg cobicistat daily.
