A Study of MT-101 in Subjects With CD5+ Relapsed/Refractory TCL (IMAGINE)

November 9, 2023 updated by: Myeloid Therapeutics

A Phase 1/2, Open-Label, First-in-human, Multiple Ascending Dose Multicenter Study of MT-101 in Subjects With CD5+ Relapsed/Refractory T Cell Lymphoma

This is a Phase 1/2 study to test the safety, tolerability, and efficacy of the investigational agent MT-101 in patients with T cell Lymphoma. MT-101 is made with myeloid cells collected from the patient's blood. The myeloid cells are modified and later infused back into their veins. The modified myeloid cells recognize the tumor cells and are designed to target and kill them.

Study Overview

Status

Status

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

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

The research study is divided into two parts. The first part will be to determine the safety and tolerability of the study drug product. During this part of the study, there will be 4 groups of study patients. The first group of patients will receive a low dose of cells, the second group will receive the low dose of cells and lymphodepleting chemotherapy to reduce the number of T cells in the blood, the third group will receive a higher dose of cells, and the fourth group will receive the higher dose of cells and lymphodepleting chemotherapy to reduce the number of T cells in the blood. In the second part of the study, cells with or without chemotherapy will be administered based on results of Part 1 and the safety, tolerability, and efficacy of MT-101 will be assessed. All patient groups will receive 6 doses of drug product over 3 weeks.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Safety and tolerability of the drug will be determined based on observed adverse events (AEs), including all potential dose limiting toxicities.
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants.

Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
