The purpose of this study is to evaluate the safety and tolerability of MT-3724 in combination with gemcitabine and oxaliplatin (GEMOX) in participants with relapsed or refractory B-Cell NHL.
Read the detailed description
This is a multi-center, open-label two-part study evaluating the safety and tolerability of MT-3724 in combination with GEMOX in relapsed or refractory B-cell Lymphoma patients.
Part 1: (MT-3724 Dose Escalation) Define the maximum tolerated dose (MTD) of MT-3724 in combination with standard treatment of GEMOX
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 GEMOX. In addition, the PK, PD, immunogenicity and tumor response at the MTD of MT-3724 in combination with GEMOX will be more thoroughly evaluated in Part 2.
In original protocol and amendment 2, participants will be administered intravenous (IV) MT-3724 over 1 hour on Days 1, 3, 5, 8, 10 and 12 in Cycles 1 and 2 (each 28-day cycle) and on Days 1, 8, 15, and 22 in Cycles 3 and 4 (each 28-day cycle). Participants will also be administered Gemcitabine 1000 milligrams per meter square (mg/m^2) as 30-minute IV infusion and Oxaliplatin 100 mg/m^2 as 2-hour IV infusion on Days 2 and 16 in Cycles 1, 2, 3 and 4 (each 28-day cycle). Per amendment 2, participants will be administered MT-3724 on Days 1, 3, 5, 8, 10, 12, 15, 22, 29, and 36 in Cycle 1 (42-day cycle). In Cycles 2, 3 and 4, MT-3724 will be administered weekly on Days 1, 8, 15, and 22 of each 28-day cycle. Gemcitabine and oxaliplatin will be administered on Days 16 and 30 of Cycle 1 and on Days 2 and 16 in Cycles 2, 3 and 4 (42-day cycle for Cycle 1 and 28-day cycle for Cycle 2, Cycle 3 and Cycle 4).
Continued Treatment with MT-3724 in combination with GEMOX will continue for four cycles of until death, disease progression, unacceptable toxicity, withdrawal of consent or another reason for withdrawal.
After four cycles, the participants who experience clinical benefit can continue MT-3724 treatment with additional cycles of 28 days each (either alone or in combination with GEMOX) if supported by the investigator's assessment of the benefit-risk ratio, after consultation with sponsor and Medical Monitor

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the safety and tolerability of MT-3724 in combination with gemcitabine and oxaliplatin (GEMOX) in participants with relapsed or refractory B-Cell NHL.
Detailed description
This is a multi-center, open-label two-part study evaluating the safety and tolerability of MT-3724 in combination with GEMOX in relapsed or refractory B-cell Lymphoma patients.
Part 1: (MT-3724 Dose Escalation) Define the maximum tolerated dose (MTD) of MT-3724 in combination with standard treatment of GEMOX
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 GEMOX. In addition, the PK, PD, immunogenicity and tumor response at the MTD of MT-3724 in combination with GEMOX will be more thoroughly evaluated in Part 2.
In original protocol and amendment 2, participants will be administered intravenous (IV) MT-3724 over 1 hour on Days 1, 3, 5, 8, 10 and 12 in Cycles 1 and 2 (each 28-day cycle) and on Days 1, 8, 15, and 22 in Cycles 3 and 4 (each 28-day cycle). Participants will also be administered Gemcitabine 1000 milligrams per meter square (mg/m^2) as 30-minute IV infusion and Oxaliplatin 100 mg/m^2 as 2-hour IV infusion on Days 2 and 16 in Cycles 1, 2, 3 and 4 (each 28-day cycle). Per amendment 2, participants will be administered MT-3724 on Days 1, 3, 5, 8, 10, 12, 15, 22, 29, and 36 in Cycle 1 (42-day cycle). In Cycles 2, 3 and 4, MT-3724 will be administered weekly on Days 1, 8, 15, and 22 of each 28-day cycle. Gemcitabine and oxaliplatin will be administered on Days 16 and 30 of Cycle 1 and on Days 2 and 16 in Cycles 2, 3 and 4 (42-day cycle for Cycle 1 and 28-day cycle for Cycle 2, Cycle 3 and Cycle 4).
Continued Treatment with MT-3724 in combination with GEMOX will continue for four cycles of until death, disease progression, unacceptable toxicity, withdrawal of consent or another reason for withdrawal.
After four cycles, the participants who experience clinical benefit can continue MT-3724 treatment with additional cycles of 28 days each (either alone or in combination with GEMOX) if supported by the investigator's assessment of the benefit-risk ratio, after consultation with sponsor and Medical Monitor

Primary outcome
Part 1 and 2: Number of Participants With Dose Limiting Toxicities (DLTs)
Time frame: Up to 168 Days
A DLT is any treatment-emergent adverse event (TEAE) that occurred after the start of infusion in cycle 1 of Part 1 and the TEAE is at least possibly related to the study drug, as determined by the sponsor after consultation with the investigator(s).
Part 1 and 2: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Time frame: Up to 168 Days
An AE is as any untoward medical occurrence in a participant or clinical investigation in a participant administered a pharmaceutical product(s) and which does not necessarily have to have a causal relationship with this experimental intervention(s). A SAE is any AE that is fatal or life-threatening, permanently disabling (incapacitating or interfering with the ability to resume usual life patterns), results in unplanned in-subject hospitalization or prolongation of an existing hospitalization, results in a congenital abnormality or birth defect, or any other situation that require medical or scientific judgement. Number of participants with common >=0 percent (%) TEAEs and SAEs are presented.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing MT-3724, Gemcitabine and Oxaliplatin in people with Non-hodgkin Lymphoma,B Cell and Refractory Diffuse Large B-Cell Lymphoma, run by Molecular Templates, Inc. at 9 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 38 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 16 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Aug 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part 1 and 2: Number of Participants With Dose Limiting Toxicities (DLTs) (time frame: Up to 168 Days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2022.
