Participants receive BL-B01D1 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.

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

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.

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

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

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 .

Maximum serum concentration (Cmax) of BL-B01D1 will be investigated.

Time to maximum serum concentration (Tmax) of BL-B01D1 will be investigated.

Half-life (T1/2) of BL-B01D1 will be investigated.

AUC0-t is defined as area under the serum concentration-time curve from time 0 to the time of the last measurable concentration.

CL in the serum of BL-B01D1 per unit of time will be investigated.

Ctough is defined as the lowest serum concentration of BL-B01D1 prior to the next dose will be administered.

Incidence and titer of ADA of BL-B01D1 will be evaluated.

Incidence and titer of Nab of BL-B01D1 will be evaluated.

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.

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 \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]).

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.

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.

The OS is defined as the time from randomization to death (from any cause).
