Brief Summary:

In phase Ia study, the safety and tolerability of BL-B01D1 in patients with locally advanced or metastatic solid tumor will be investigated to determine the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) of BL-B01D1.

In phase Ib study, the safety and tolerability of BL-B01D1 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-B01D1 in patients with locally advanced or metastatic solid tumor will be evaluated.

Arm Intervention/treatment
Experimental: Study treatment
Participants receive BL-B01D1 as intravenous infusion for the first cycle (4 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-B01D1
Administration by intravenous infusion




Primary Outcome Measures :
  1. Phase Ia: Dose limiting toxicity (DLT) [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    DLTs are assessed according to NCI-CTCAE v5.0 during the first cycle (28 days) 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.

  2. Phase Ia: Maximum tolerated dose (MTD) [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle (within 28 days of the first administration)

  3. Phase Ib: Recommended Phase II Dose (RP2D) [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    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-B01D1


Secondary Outcome Measures :
  1. Treatment-Emergent Adverse Event (TEAE) [ Time Frame: Up to approximately 24 months ]
    TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of BL-B01D1 . The type, frequency and severity of TEAE will be evaluated during the treatment of BL-B01D1 .

  2. Cmax [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    Maximum serum concentration (Cmax) of BL-B01D1 will be investigated.

  3. Tmax [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    Time to maximum serum concentration (Tmax) of BL-B01D1 will be investigated

  4. T1/2 [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    Half-life (T1/2) of BL-B01D1 will be investigated.

  5. AUC0-t [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    AUC0-t is defined as area under the serum concentration-time curve from time 0 to the time of the last measurable concentration.

  6. CL (Clearance) [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    CL in the serum of BL-B01D1 per unit of time will be investigated.

  7. Ctrough [ Time Frame: Up to 28 days after the first dose of BL-B01D1 ]
    Ctough is defined as the lowest serum concentration of BL-B01D1 prior to the next dose will be administered.

  8. ADA (anti-drug antibody) [ Time Frame: Up to approximately 24 months ]
    Incidence and titer of ADA of BL-B01D1 will be evaluated.

  9. Nab (neutralizing antibody) [ Time Frame: Up to approximately 24 months ]
    Incidence and titer of Nab of BL-B01D1 will be evaluated.

  10. Objective Response Rate (ORR) [ Time Frame: Up to approximately 24 months ]
    ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.

  11. Disease Control Rate (DCR) [ Time Frame: Up to approximately 24 months ]
    The DCR is defined as the percentage of participants who has a CR, PR, or Stable Disease (SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease [PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD]).

  12. Duration of Response (DOR) [ Time Frame: Up to approximately 24 months ]
    The DOR for a responder is defined as the time from the participant's initial objective response to the first date of either disease progression or death, whichever occurs first.

  13. Progression-free Survival (PFS) [ Time Frame: Up to approximately 24 months ]
    The PFS is defined as the time from the participant's first dose of BL-B01D1 to the first date of either disease progression or death, whichever occurs first.
