- Registration Number
- NCT06943521
- Lead Sponsor
- Mitsubishi Tanabe Pharma America Inc.
- Brief Summary
This is a First In Human (FIH), multicenter, open-label, Phase I/II study to evaluate safety, tolerability, Pharmacokinetics (PK), pharmacodynamics, and efficacy of MT-4561 in patients with advanced solid tumors. This study will be conducted in 3 parts.
Part 1 is aimed at evaluating safety, tolerability, PK and pharmacodynamics of MT-4561 and determining the Maximum Tolerated Dose (MTD) using the Bayesian Optimal Interval (BOIN) design.
The study details and doses of Part 2 (dose-optimization) and Part 3 (Drug-Drug Interaction) will be available after review of applicable Part 1 results.

Group Intervention Description Part 1 (Dose-escalation) MT-4561 Intravenous (IV) infusion of MT-4561 once every week in 28-day cycle, until disease progression or discontinuation criteria are met.
- Primary Outcome Measures
Name Time Method Incidence of Adverse Event, Dose limiting toxicities (DLTs) a 28-day cycle Part 1 Frequency, duration, and severity (Common Terminology Criteria for Adverse Events \[CTCAE\] v5.0) of adverse events, dose limiting toxicity (DLT), physical examinations, changes in clinical laboratory values, vital signs, electrocardiogram
DLTs are defined as any event meeting the DLT criteria at least possibly related to MT-4561 for Cycle 1 (i.e., DLT monitoring window is approximately 28 days). Events with a clear alternative explanation will not be considered DLTs.Number of Patients with Adverse events (AEs) Screening through 30 days after last dose Part 1 Frequency, duration, and severity (Common Terminology Criteria for Adverse Events \[CTCAE\] v5.0) of adverse events, dose limiting toxicity (DLT), physical examinations, changes in clinical laboratory values, vital signs, electrocardiogram
Adverse event: An AE is defined as any untoward medical occurrence in a clinical study patient administered a pharmaceutical product, and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of an IMP, whether or not it is considered related to the IMP.
- Secondary Outcome Measures
Name Time Method Cmax of MT-4561 Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
area under the concentration-time curve from zero up to 168 hours post-dose (AUC0-168) Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
clearance (CL) after the first dose and at steady state Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
dose proportionality Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
accumulation ratio Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
Objective Response Rate (ORR) From Cycle 1 Day 1 until Progressive Disease/Death/or start of new anticancer therapy, up to approximately 3 years ORR defined as percentage of patients with a best overall response of complete response (CR) and partial response (PR) per Investigator review according to RECIST v1.1 criteria
Duration of Response (DOR) From Cycle 1 Day 1 until Progressive Disease/Death/or start of new anticancer therapy, up to approximately 3 years Investigator Review according to RECIST v1.1 criteria
Progression-Free Survival (PFS) From Cycle 1 Day 1 until the first documented objective disease progression or death due to any cause, whichever occurs first, up to approximately 3 years Investigator Review according to RECIST v1.1 criteria
time corresponding to occurrence of Cmax (tmax) Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
minimum observed plasma concentration (Cmin) Cycle 1 Day 1 through Cycle 2 Day 22, Cycle 3 Day 1 and Day 15, Subsequent Cycle only Day 1 (each cycle is 28 days) To determine the pharmacokinetics(PK) profile of MT-4561
