Non Hodgkin Lymphoma Clinical Trial
Pharmacokinetics, Pharmacodynamics, Safety and Tolerability of Multiple Dose Regimens of MT-3724 With Lenalidomide for the Treatment of Participants With Relapsed/Refractory B-Cell Non-Hodgkin’s Lymphoma (MT-3724_NHL_003)
Summary
The purpose of this study is to evaluate the safety and tolerability of MT-3724 in combination with Lenalidomide in participants with relapsed or refractory B-Cell NHL.
Full Description
This is a multi-center, open-label two-part study evaluating the safety and tolerability of MT-3724 in combination with Lenalidomide in relapsed or refractory CD20 positive B-cell Lymphoma participants.
Part 1: (MT-3724 Dose Escalation) Define the maximum tolerated dose (MTD) of MT-3724 in combination with standard treatment of Lenalidomide
Part 2: (MTD Expansion Cohort) Confirm the safety and tolerability of the MTD of MT-3724 from Part 1 in the MTD Expansion Cohort, where MT-3724 will be given at the MTD in combination with Lenalidomide. In addition, the Pharmacokinetics (PK), Pharmacodynamics (PD), immunogenicity and tumor response at the MTD of MT-3724 in combination with Lenalidomide will be more thoroughly evaluated in Part 2.
It is anticipated that up to 64 participants will be enrolled. Treatment will continue until disease progression, withdrawal of consent or any other reason.
Eligibility Criteria
Inclusion Criteria:
- Participants must meet ALL the following criteria to be eligible for the study.
Be adequately informed about the study and fully consent to participation as demonstrated by signing the written ICF before any screening procedure.
Be aged ≥18 years years on the date of signing the informed consent form.
Have relapsed or refractory CD20 positive B-cell NHL that, in the investigator's opinion, could benefit from MT-3724+LEN therapy. Participants must have proof of CD20 positive NHL either by:
Historical biopsies (obtained with diagnosis of relapsed or refractory disease), or
Fresh biopsies.
Bone marrow biopsy
Excisional lymph node biopsy
Core biopsy of any involved organ; all are acceptable methods; FNA not acceptable
All subtypes of B-cell NHL may be considered for Part 1 (MT-3724 dose escalation). Only histologically documented DLBCL (including mixed histology) may be considered for Part 2 (MTD expansion cohort).

Albumin ≥ 3.0 g/dL
Women of reproductive potential must have a negative pregnancy test on 2 occasions during the screening period (within 10-14 days and within 24 hours before the start of treatment). Women not of reproductive potential are female participants who are postmenopausal(>1 year since last menstrual cycle) or permanently sterilized (e.g., hysterectomy, bilateral salpingectomy).
Males must agree to always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking LEN and for up to 4 weeks after discontinuing LEN, even if they have undergone a successful vasectomy. Male participants taking LEN must not donate sperm.
Participants of reproductive potential and their partners must agree to either to abstain continuously from heterosexual intercourse or to use 2 methods of reliable birth control simultaneously to begin 4 weeks prior to initiating treatment with LEN until 28 days after the last dose of MT-3724 or LEN. The investigator or a designated associate should advise the participants how to achieve adequate contraception. The following birth control methods may be considered: one highly effective form of contraception - tubal ligation, intrauterine device (IUD), hormonal (birth control pills, injections, hormonal patches, vaginal rings, or implants), or partner's vasectomy, and one additional effective contraceptive method - male latex or synthetic condom, diaphragm, or cervical cap.
Participants must have a life expectancy of >3 months from the start of treatment.
