A Phase 1, Open-Label, Dose-Escalation & Expanded Cohort, Continuous IV Infusion, Multi-center Study of the Safety, Tolerability,PK & PD of EPZ-5676 in Treatment Relapsed/Refractory Patients With Leukemias Involving Translocation of the MLL Gene at 11q23 or Advanced Hematologic Malignancies

The purpose of this study is to determine the safe dose of EPZ-5676, to evaluate the safety of EPZ-5676 in patients with advanced hematologic malignancies, and to conduct a preliminary assessment of the anti-leukemia activity of EPZ-5676 in patients with acute leukemias bearing rearrangements of the MLL gene.

Currently this study is in the MLL-r restricted/expansion phase and is only enrolling patients with rearrangements involving the MLL gene, including 11q23 or partial tandem duplications (PTD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A subset of patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) harbor rearrangements of the MLL gene, which are detected either by cytogenetic or fluorescent in situ hybridization evaluation at the time of diagnosis. A protein called DOT1L plays an important role in the malignant process in these leukemias. EPZ-5676 is a molecule that blocks the activity of DOT1L, and is therefore being evaluated in the treatment of patients with MLL-rearranged leukemias.

The dose escalation portion has been completed. Currently this study is in the expansion phase and patients with MLL-r and MLL-PTD will receive EPZ-5676 as a 28-day continuous intravenous infusion (CIV).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
