About this trial

This trial is a registrational Phase III, randomized, open-label, multicenter study to evaluate the efficacy and safety of BL-B01D1 in combination with osimertinib in patients with unresectable EGFR-mutated Stage III non-small cell lung cancer who have not progressed following platinum-based chemoradiotherapy.

Trial outcomes

Primary outcomes

1

Progression-free survival (PFS)

Progression-free survival (PFS) as assessed by BICR is defined as the time between the date subjects were randomized and the first observation of disease progression (based on BICR's image-based assessment) or death.

Time frame
Up to approximately 24 months

Secondary outcomes

1

Overall Survival (OS)

Overall survival (OS) is defined as the time between the day the subject is randomized and the subject's death.

Time frame
Up to approximately 24 months
2

Objective Response Rate (ORR)

Objective response rate (ORR) is defined as the number of CR and PR in the treatment and control groups divided by the number of that group in the full analysis set (FAS).

Time frame
Up to approximately 24 months
3

Disease Control Rate (DCR)

Disease Control Rate (DCR) : Percentage of all randomized subjects who rated the best overall response (BOR) as complete response (CR), partial response (PR), and disease stabilization (SD) according to RECIST 1.1 criteria.

Time frame
Up to approximately 24 months
4

Duration of Response (DOR)

Duration of Response (DOR) : defined as the period from the date when tumor response is first recorded to the date when objective tumor progression is first recorded or the date of death.

Time frame
Up to approximately 24 months
