Exclusion Criteria

1. Received chemotherapy, biological therapy, immunotherapy or other antitumor treatments within 4 weeks or 5 half-lives prior to the first dose (6 weeks for mitomycin and nitrosoureas; oral fluorouracil drugs, etc.).
2. Prior treatment with an ADC drug containing a camptothecin derivative (topoisomerase I inhibitor) as a toxin.

4. A history of severe cardiovascular and cerebrovascular diseases.
5. Active autoimmune or inflammatory diseases.
6. Patients with other malignant tumors within 5 years before the first administration.
7. Unstable deep vein thrombosis, arterial thrombosis, and pulmonary embolism requiring medical intervention within 6 months before screening; Infusion-related thrombosis was excluded.
8. Patients with poorly controlled pericardial effusion, pleural effusion, peritoneal effusion, or pelvic effusion with clinical symptoms were judged by the investigator to be ineligible for enrollment.
9. Hypertension poorly controlled by antihypertensive drugs (systolic BP > 150 mmHg or diastolic blood pressure > 100 mmHg).
10. Current interstitial lung disease, drug-induced interstitial pneumonia, radiation pneumonitis requiring steroid therapy, or a history of these diseases.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
BL-M07D1	BL-M07D1	Participants receive BL-M07D1 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.

Primary Outcome Measures

Name	Time	Method
Phase II: Objective Response Rate (ORR)	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.
Phase Ib: Recommended Phase II Dose (RP2D)	Up to 21 days after the first dose	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-M07D1.

Secondary Outcome Measures

Name	Time	Method
Progression-free Survival (PFS)	Up to approximately 24 months	The PFS is defined as the time from the participant's first dose of BL-M07D1 to the first date of either disease progression or death, whichever occurs first.
Cmax	Up to 21 days after the first dose	Maximum serum concentration (Cmax) of BL-M07D1 will be investigated.
Treatment-Emergent Adverse Event (TEAE)	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-M07D1. The type, frequency and severity of TEAE will be evaluated during the treatment of BL-M07D1.
Phase Ib: Objective Response Rate (ORR)	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.
Disease Control Rate (DCR)	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 \[PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD\]).
Tmax	Up to 21 days after the first dose	Time to maximum serum concentration (Tmax) of BL-M07D1 will be investigated.
Ctrough	Up to 21 days after the first dose	Ctrough is defined as the lowest serum concentration of BL-M07D1 prior to the next dose will be administered.
Duration of Response (DOR)	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.
ADA (anti-drug antibody)	Up to approximately 24 months	Frequency of anti-BL-M07D1 antibody (ADA) will be investigated.
