• 1 other identifier: BL-M02D1-102
• Study Type: interventional
• Target: 22
• Locations: 1 country
• Sites: 1

Brief Summary

In phase Ia study, the safety and tolerability of BL-M02D1 in patients with locally advanced or metastatic gastroenteric tumor or other solid tumors will be investigated to determine the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) of BL-M02D1. In phase Ib study, the safety and tolerability of BL-M02D1 at the phase Ia recommended dose will be further investigated, and recommended phase II dose (RP2D) for phase II clinical studies will be determined. In addition, the preliminary efficacy, pharmacokinetic characteristics, and immunogenicity of BL-M02D1 in patients with locally advanced or metastatic gastroenteric tumor or other solid tumors will be evaluated.

Conditions

Locally Advanced or Metastatic Digestive Tract Tumors; 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-M02D1.

  Up to 21 days after the first dose

Secondary Outcomes (13)

• Treatment-Emergent Adverse Event (TEAE)

  Up to approximately 24 months

• Cmax

  Up to 21 days after the first dose

• Tmax

  Up to 21 days after the first dose

• T1/2

  Up to 21 days after the first dose

• AUC0-t

  Up to 21 days after the first dose

Study Arms (1)

Study treatment

EXPERIMENTAL

Participants receive BL-M02D1 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-M02D1

Interventions

BL-M02D1 DRUG

Administration by intravenous infusion

Study treatment

Or decreased hemoglobin except ≥90 g/L).
• Has adequate organ function before registration, defined as: a) Bone marrow function: Absolute neutrophil count (ANC) ≥1.5×109/L, Platelet count ≥90×109/L, Hemoglobin ≥90 g/L; B) Hepatic function: Total bilirubin (TBIL≤1.5 ULN), AST and ALT ≤2.5 ULN for participants without liver metastasis, AST and ALT ≤5.0 ULN for liver metastases; c) Renal function: Creatinine (Cr) ≤1.5 ULN, or creatinine clearance (Ccr) ≥50 mL/min (according to the Cockcroft and Gault formula).
• Coagulation function: International normalized ratio (INR)≤1.5×ULN, and activated partial thromboplastin time (APTT)≤1.5ULN.
• Urinary protein ≤2+ or ≤1000mg/24h.
• For premenopausal women with childbearing potential, a pregnancy test must be taken within 7 days prior to the start of treatment. Serum or urine pregnancy must be negative and must be non-lactating. Adequate barrier contraceptive measures should be taken during the treatment and 6 months after the end of treatment for all participants (regardless of male or female).
