Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of Participants With Dose-limiting Toxicities Following Treatment With DS-1471a (Dose Escalation) | Cycle 1: Baseline up to Day 28 (each cycle is 28 days) |
| Number of Participants With Treatment-emergent Adverse Events Following Treatment With DS-1471a (Dose Escalation and Expansion) | Baseline up to 60 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DoR) As Assessed by the Investigator in Participants Following Treatment With DS-1471a (Dose Escalation and Expansion) | Baseline up to 60 months | Duration of response (DoR) is defined as the time from first documentation of CR or PR to the date of the first documentation of PD as assessed by the investigator or to the date of death due to any cause, whichever occurs first. As per RECIST v1.1, CR is defined as a disappearance of all target lesions and PR is defined as at least a 30% decrease in the sum of diameters of target lesions. |
| Progression-free Survival (PFS) of Participants With Advanced Solid Tumors Following Treatment With DS-1471a (Dose Escalation and Expansion) | Baseline up to 60 months | Progression-free survival (PFS) is defined as the time from the start date of study drug to the date of the first documentation of objective PD as assessed by the investigator or to the date of death due to any cause, whichever occurs first. As per RECIST v1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. |
| Overall Survival (OS) of Participants With Advanced Solid Tumors Following Treatment With DS-1471a (Dose Escalation and Expansion) | Baseline up to 60 months | Overall survival (OS) is defined as the time from the date of the start of study drug to the date of death due to any cause. |
| Objective Response Rate (ORR) of Participants With Advanced Solid Tumors Following Treatment With DS-1471a (Dose Expansion) | Baseline up to 60 months | Confirmed objective response rate (ORR) is defined as the proportion of participants who have a confirmed BOR of CR or PR as assessed by the investigator. As per RECIST v1.1, CR is defined as a disappearance of all target lesions and PR is defined as at least a 30% decrease in the sum of diameters of target lesions. |
| Disease Control Rate (DCR) of Participants With Advanced Solid Tumors Following Treatment With DS-1471a (Dose Expansion) | Baseline up to 60 months | Disease control rate (DCR) is defined as the proportion of participants who have a BOR of CR, PR, or SD as assessed by the investigator. As per RECIST v1.1, CR is defined as a disappearance of all target lesions, PR is defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD (at least a 20% increase in the sum of diameters of target lesions). |
| Best Overall Response (BOR) As Assessed by the Investigator in Participants Following Treatment With DS-1471a (Dose Escalation and Expansion) | Baseline up to 60 months | Best overall response (BOR) is recorded from the start of study drug until documented progressive disease (PD) or start of any anticancer treatment, whichever occurs first. Confirmation of complete response (CR) or partial response (PR) is required. As per Response Evaluation Criteria In Solid Tumors (RECIST) v1.1, CR is defined as a disappearance of all target lesions, PR is defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD (at least a 20% increase in the sum of diameters of target lesions). |
| Pharmacokinetic Analysis Time to Reach Maximum Plasma Concentration (Tmax) of DS-1471a | Cycle 1 (Days 1, 2, 4, 8, 15, and 22), Cycle 2 (Day 1), Cycle 3 (Days 1, 2, 4, 8, 15, and 22), Cycles 4, 6, and 8 (Day 1), each cycle is 28 days | — |
