Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Lymphoma, T-Cell, Peripheral Lymphoma, T-Cell, Cutaneous Mycosis Fungoides Adoptive Cellular Immunotherapy Cell Therapy Biological: MT-101 Other: MT-101 + Conditioning (Lymphodepleting) Chemotherapy Phase 1 Phase 2

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.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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
Actual Study Start Date : December 15, 2021
Estimated Primary Completion Date : November 2023
Estimated Study Completion Date : October 2024

Arm Intervention/treatment
Experimental: Cohort 1 and Cohort 3
Biological: MT-101
CD5 ATAK cells

Experimental: Cohort 2 and Cohort 4
MT-101 preceded by conditioning (lymphodepleting) chemotherapy
Other: MT-101 + Conditioning (Lymphodepleting) Chemotherapy
IV administration of fludarabine and cyclophosphamide

Primary Outcome Measures :
  1. Safety and Tolerability of MT-101 [ Time Frame: 4 weeks ]
    Safety and tolerability of the drug will be determined based on observed adverse events (AEs), including all potential dose limiting toxicities.

Secondary Outcome Measures :
  1. MT-101 cell kinetics in blood [ Time Frame: 4 weeks ]
    The quantity of MT-101 RNA in the blood.

  2. The objective response rate [ Time Frame: 24 weeks ]
    The ORR is defined as the number (%) of subjects achieving a best overall response of complete response (CR) or partial response (PR)

Other Outcome Measures:
  1. Duration of response (DOR) [ Time Frame: 48 weeks ]
    DOR is the time interval between the date of first assessment of PR or CR to the date of the follow-on first documentation of progressive disease or death, whichever occurs earlier.

  2. Progression free survival (PFS) [ Time Frame: 48 weeks ]
    PFS is defined as the time from the date of the first administration of MT-101 to the date of first documentation of progressive disease or death, whichever occurs earlier.

  3. Overall survival (OS) [ Time Frame: 48 weeks ]
    OS is defined as the time from date of the first administration of MT-101 to the date of death.
