• 1 other identifier: BL-M24D1-101
• Study Type: interventional
• Target: 33
• Locations: 1 country
• Sites: 1

Brief Summary

This study is an open, multicenter, non-randomized phase I clinical trial to evaluate the safety, tolerability, pharmacokinetic characteristics, and preliminary efficacy of BL-M24D1 in patients with locally advanced or metastatic non-small cell lung cancer and other solid tumors.

Conditions

Non Small Cell Lung Cancer; Solid Tumor

Outcome Measures

Primary Outcomes (3)

• Phase Ia: Dose limiting toxicity (DLT)

  DLTs are assessed according to NCI-CTCAE v5.0 during the first cycle and defined as occurrence of any of the toxicities in DLT definition if judged by the investigator to be possibly, probably or definitely related to study drug administration.

  Up to 28 days after the first dose

• Phase Ia: Maximum tolerated dose (MTD)

  MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle.

  Up to 28 days after the first dose

• Phase Ib: Recommended Phase II Dose (RP2D)

  The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of BL-M24D1.

  Up to approximately 24 months

Secondary Outcomes (11)

• Treatment-Emergent Adverse Event (TEAE)

  Up to approximately 24 months

• Cmax

  Up to approximately 24 months

• Tmax

  Up to approximately 24 months

• T1/2

  Up to approximately 24 months

• AUC0-t

  Up to approximately 24 months

Study Arms (1)

BL-M24D1

EXPERIMENTAL

Participants receive BL-M24D1 as intravenous infusion for the first cycle (2 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Drug: BL-M24D1

Interventions

BL-M24D1 DRUG

Administration by intravenous infusion for a cycle of 2 weeks.

BL-M24D1
