• 1 other identifier: BL-B16D1-101
• Study Type: interventional
• Target: 21
• Locations: 1 country
• Sites: 1

Brief Summary

This study is an open, multicenter, dose-escalation and expansion-enrollment and nonrandomized phase I clinical study to evaluate the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of BL-B16D1 in locally advanced or metastatic solid tumors.

Conditions

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 21 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 21 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-B16D1.

  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-B16D1

EXPERIMENTAL

Participants receive BL-B16D1 as intravenous infusion for the first cycle (3 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-B16D1

Interventions

BL-B16D1 DRUG

Administration by intravenous infusion for a cycle of 3 weeks.

BL-B16D1
