DS-3201b for Acute Myelogenous Leukemia (AML) or Acute Lymphocytic Leukemia (ALL)

January 29, 2024 updated by: Daiichi Sankyo, Inc.

A Phase 1 Study of DS-3201b in Subjects With Acute Myelogenous Leukemia (AML) or Acute Lymphocytic Leukemia (ALL)

This research study tests an investigational drug called DS-3201b. An investigational drug is a medication that is still being studied and has not yet been approved by the United States Food and Drug Administration (FDA). The FDA allows DS-3201b to be used only in research. It is not known if DS-3201b will work or not.

This study consists of two parts. The first part (Part 1) is a dose escalation that will enroll subjects with AML or ALL that did not respond or no longer respond to previous standard therapy. The purpose of Part 1 of this research study is to determine the highest dose a patient can tolerate or recommended dose of DS-3201b that can be given to subjects with AML or ALL. Once the highest tolerable dose is determined, additional subjects will be enrolled at that dose into Part 2 of the study.

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

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Any Grade Treatment-emergent Adverse Event Classified as Dose-limiting Toxicities (Dose Escalation)
Time Frame: Baseline up to Day 28
Dose-limiting toxicity (DLT) is defined as a clinically significant non-hematologic treatment-emergent adverse event (TEAE) or abnormal clinical laboratory value that is clearly not related to disease progression, intercurrent illness, and occurring during the first cycle (28 days) on study that meets any of the following criteria: National Cancer Institute (NCI) - Common Terminology Criteria for Adverse Events (CTCAE), Version 4 Grade 3 aspartate aminotransferase (AST) (SGOT), alanine aminotransferase (ALT) (SGPT), or bilirubin for ≥7 days; NCI-CTCAE Grade 4 AST (SGOT) or ALT (SGPT) of any duration; All Grade 4 non-hematologic toxicities of any duration; Any Grade 5 toxicity, unless proven to be clearly and incontrovertibly related to disease progression or intercurrent illness will constitute a DLT; All other clinically significant, non-hematological NCI-CTCAE Grade 3/4 AEs. AEs were coded using the MedDRA dictionary, Version 23.0.
Baseline up to Day 28
Number of Participants Who Experienced Any Grade Treatment-emergent Adverse Event (Dose Escalation)
Time Frame: Baseline up to 30 days after last study dose, up to approximately 4 years
A treatment-emergent adverse event (TEAE) is defined as an adverse event (AE) that occurs, having been absent before the first dose of study drug or has worsened after initiating the study drug until 30 days after the last dose of the study drug. AEs were coded using the MedDRA dictionary, Version 23.0.
Baseline up to 30 days after last study dose, up to approximately 4 years
