JRCT ID: jRCT2031240057

Registered date:27/04/2024

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Ovarian Cancer, Solid Tumors
• Date of first enrollment: 20/05/2024
• Target sample size: 25
• Study type: Interventional

Intervention(s)

Phase 1 Part and Phase 2 Part: TAK-853:
TAK-853, 6.0 mg/kg, injection, intravenously (IV), once every 3 weeks. Patients will continue to receive study drug until disease progression, unacceptable toxicity, withdrawal of consent, death, or until the sponsor terminates the study (whichever comes first).

Outcome(s)

Primary Outcome

1.Phase 1 Part: Number of Participants with Dose-Limiting Toxicities (DLTs) in Cycle 1
Time Frame: Up to 21 days
Toxicity will be evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0. DLT will be defined as any of the events specified in the protocol that are considered by the investigator to be at least possibly related to therapy with study medications.

2.Phase 1 Part: Number of Participants with Treatment-emergent Adverse Events (TEAEs)
Time Frame: 1 year
An adverse event (AE) means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence 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), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. This includes any newly occurring event, or a previous condition that has increased in severity or frequency since the administration of study drug.

3.Phase 1 Part: Number of Participants with Grade 3 or Higher TEAEs
Time Frame: 1 year
A severity grade is defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0. Grade 1 scales as Mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2 scales as Moderate (minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living [ADL]); Grade 3 scales as Severe (severe or medically significant but not immediately life threatening hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL); Grade 4 scales as Life-threatening consequences, urgent intervention indicated, and Grade 5 scales as Death related to Adverse Event (AE).

4.Phase 1 Part: Number of Participants with Serious TEAEs
Time Frame: 1 year
An SAE is any untoward medical occurrence or effect that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability / incapacity, is a congenital anomaly / birth defect or is medically important due to other reasons than the above mentioned criteria.

5.Phase 1 Part: Number of Participants with TEAEs Leading to Drug Discontinuation.
Time Frame: 1 year

6.Phase 1 Part: Number of Participants with TEAEs Leading to Infusion Interrupted
Time Frame: 1 year

7.Phase 1 Part: Number of Participants with TEAEs Leading to Dose Delayed
Time Frame: 1 year

8.Phase 1 Part: Number of Participants with TEAEs Leading to Dose Reduction
Time Frame: 1 year

9.Phase 1 Part: Number of Participants with Adverse Event of Clinical Interest (AECIs)
Time Frame: 1 year
An AE of clinical interest (serious or nonserious) is one of scientific and medical concern specific to the TAK-853, for which ongoing monitoring. Such events may require further investigation to characterize and understand them. AECIs for TAK-853 include: Ocular AEs, Pneumonitis, Peripheral neuropathy, and Infusion related reactions

10.Phase 2 Part: Overall Response Rate (ORR) Assessed by Investigator with RECIST 1.1
Time Frame: 2 year
The ORR is defined as the percentage of participants who achieved a confirmed Partial response (PR) or confirmed Complete response (CR) during the study using RECIST v1.1. Disease response criteria on RECIST 1.1 are following; Complete response (CR): Disappearance of all target lesions. Partial response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. Progressive disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions. Stable disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.

DOR Responders without documentation of progressive disease will be censored at the date of last response assessment that is SD or better.
