New drug aims to outdo chemo for lung cancer patients Who've run out of options

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Toxicity of previous antineoplastic therapy has returned to ≤ grade 1 defined by NCI-CTCAE v5.0; 12. No severe cardiac dysfunction, left ventricular ejection fraction ≥50%; 13. The level of organ function must meet the requirements on the premise that blood transfusion is not allowed within 14 days before the screening period and no cell growth factor drugs are allowed; 14. Coagulation function: international normalized ratio (INR) ≤1.5 and activated partial thromboplastin time (APTT) ≤1.5×ULN; 15. Urine protein ≤2+ or \< 1000mg/24h; 16. For premenopausal women with childbearing potential, a pregnancy test must be performed within 7 days before the start of treatment, serum or urine must be negative for pregnancy, and must be non-lactating; All enrolled patients (male or female) were advised to use adequate barrier contraception throughout the treatment cycle and for 6 months after the end of treatment. Exclusion Criteria: 1. The patient has histologic or cytologic evidence of small cell or mixed small/non-small cell component or squamous non-small cell lung cancer; 2.

Previous treatment with: a. an ADC with TOPI inhibitor as toxin; b. any systemic therapy in the context of metastatic/locally advanced disease; 4. The history of severe cardiovascular and cerebrovascular diseases in the past six months prior screening; 5. Thrombotic events requiring therapeutic intervention within 6 months before screening; Infusion-related thrombosis more than 4 weeks later was excluded; 6. Complete left bundle branch block, III degree atrioventricular block, frequent and uncontrolled severe arrhythmia; 7. Other malignancies diagnosed within 3 years before randomization; 8. Hypertension poorly controlled by two antihypertensive drugs; 9. History of interstitial lung disease (ILD) requiring steroid therapy, or current ILD or grade ≥2 radiation pneumonitis; 10.

Severe infection within 4 weeks before randomization; Evidence of pulmonary infection or active pulmonary inflammation within 2 weeks before randomization; 14. Patients with massive or symptomatic effusions or poorly controlled effusions; 15. Imaging examination showed that the tumor had invaded or wrapped the abdomen, chest, neck, and large blood vessels; 16. Severe unhealed wound, ulcer, or fracture within 4 weeks before signing the informed consent; 17. Subjects with clinically significant bleeding or obvious bleeding tendency within 4 weeks before signing the informed consent; 18. Patients with inflammatory bowel disease, extensive bowel resection history, immune enteritis history, intestinal obstruction or chronic diarrhea; 19. Have a history of allergy to recombinant humanized antibodies or any of the ingredients of BL-B01D1; 20. Human immunodeficiency virus antibody positive, active hepatitis B virus infection, or hepatitis C virus infection; 21. A history of severe neurological or psychiatric illness; 22. Received other unmarketed investigational drug or treatment within 4 weeks before randomization; 23. Subjects who were scheduled to receive live vaccine or received live vaccine within 28 days before study randomization; 24. Other circumstances that were assessed by the investigator as inappropriate for participation in the trial.
