Brief Summary

The objective of this study is to evaluate the safety, tolerability, and efficacy of BL-B01D1 in patients with Metastatic or Unresectable Non-Small Cell Lung Cancer (NSCLC) and Other Solid Tumors.

Detailed Description

BL-B01D1-LUNG-101 is a global, multi-center, Phase 1 study to evaluate the safety, tolerability, pharmacokinetics , and initial efficacy of BL-B01D1 in participants with metastatic or unresectable NSCLC and Other Solid Tumors.

This study will be conducted in two different dosing schedules (Cohort A and Cohort B) and three parts (dose escalation, dose finding and dose expansion). Cohort A will be dosed on Day 1 and Day 8 of a continuous 21-day treatment cycle. Cohort B will be dosed on Day 1 of a continuous 21-day treatment cycle. Each Cohort has different dose groups.

Arm && Interventions

Group	Intervention	Description
BL-B01D1 administered Day 1 and Day 8 per cycle	BL-B01D1	BL-B01D1 will be administered on Day 1 and Day 8 by intravenous infusion every 3 weeks
BL-B01D1 administered Day 1 per cycle	BL-B01D1	BL-B01D1 will be administered on Day 1 via by intravenous infusion every 3 weeks

Primary Outcome Measures

Name	Time	Method
Participants with Serious Adverse Events (SAEs) and treatment-emergent adverse events (TEAEs),	One year	Measuring the number of patients with serious adverse events (SAEs) and treatment-emergent adverse events (TEAEs)
Participants with abnormal lab results	One year	Measure the number of participants with abnormal clinical laboratory values
To determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) and two or more recommended doses and schedules for recommended dose expansion (RDEs) of BL-B01D1 in metastatic NSCLC	One year	Determine the highest BL-B01D1 dose level at which ≤33% subjects experience a DLT during the DLT evaluation period and highest BL-B01D1 dose administered in the event and MTD cannot be defined.
Participants with Dose-limiting toxicities	One year	Measuring the number of patients Dose-limiting toxicities (DLTs). A DLT is defined as any of the following events that are not clearly due to the underlying disease or extraneous causes: Hematological toxicities: * Grade 4 neutrophil count decreased lasting \>7 days; * Grade ≥3 febrile neutropenia; * Grade ≥3 platelet count decreased with clinically significant hemorrhage.; Non-Hematological toxicities: * Death; * Hy's law cases; * Grade ≥3 non-hematological toxicities,
Participants with abnormal physical examination findings	One year	Measure the number of participants with abnormal physical examination findings.
Participants with ability to care for themselves, daily activity, and physical activity	One year	Measure the change in participants with Eastern Clinical Oncology Group (ECOG) Scale of Performance Status. The scale is 0-4 with 0 being the fully active (best outcome) and 4 being completely disabled (worst outcome)
Participants with abnormal ECG reading	One year	Measure the number of participants with abnormal ECG parameters
