Details and patient eligibility

About

A phase III, randomized, open-label, multicenter study to evaluate the efficacy and safety of BL-B01D1 in patients with recurrent or metastatic nasopharyngeal carcinoma who had failed at least two lines of platinum-based chemotherapy after receiving PD-1/PD-L1 monoclonal antibody as the last line of therapy.

Full description

Primary objective: To evaluate BICR-based objective response rate (ORR) and overall survival (OS) benefit of BL-B01D1 versus physician's choice of chemotherapy.

Enrollment

368 estimated patients

Sex

All

Ages

18+ years old

Volunteers

No Healthy Volunteers

Inclusion criteria

  1. Voluntarily sign the informed consent and follow the requirements of the protocol.

  2. No gender limit.

  3. Age ≥18 years old.

  4. expected survival time ≥3 months.

  5. Patients with histologically or cytologically confirmed recurrent or metastatic nasopharyngeal carcinoma treated with PD-1/PD-L1 monoclonal antibody after failure of at least two lines of chemotherapy (at least one line of platinum-based).

  6. Patients who are suitable for the final line treatment with the control chemotherapy drugs specified in this protocol.

  7. Must have at least one measurable lesion according to RECIST v1.1 definition;

    1. If a single measurable lesion is present, baseline imaging of the lesion should not be performed until at least 14 days after biopsy has been performed, if biopsy has been performed;
    2. If the target lesion at the previous radiotherapy site was the only measurable lesion, investigators were required to provide pre-and post-imaging data showing significant progression of the lesion to confirm definite progression, at least 3 months before the end of radiotherapy.
  8. ECOG 0 or 1.

  9. Toxicity from previous antineoplastic therapy has returned to grade 1 or less as defined in NCI-CTCAE v5.0 (except alopecia, fatigue, hyperpigmentation, hormone-replacement stable hypothyroidism, grade 2 peripheral neurotoxicity after chemotherapy, or other eligibility criteria).

  10. No severe cardiac dysfunction, left ventricular ejection fraction ≥50%.

  11. No blood transfusion, no use of cell growth factors and/or platelet-raising agents within 14 days prior to the first dose of study drug, and organ function levels that meet the following criteria:

    1. Bone marrow function: absolute neutrophil count (ANC) ≥1.5×109/L, platelet count ≥100×109/L, hemoglobin ≥100 g/L;
    2. Liver function: total bilirubin ≤1.5×ULN (total bilirubin ≤3×ULN in subjects with Gilbert's syndrome or liver metastasis), AST and ALT ≤2.5×ULN in patients without liver metastasis, AST and ALT ≤5.0×ULN in patients with liver metastasis;
    3. Renal function: creatinine (Cr) ≤1.5×ULN, or creatinine clearance (Ccr) ≥50 mL/min (according to Cockcroft and Gault formula).
  12. Coagulation function: international normalized ratio (INR) ≤1.5 and activated partial thromboplastin time (APTT)≤1.5×ULN.

  13. Urine protein ≤2+ or < 1000mg/24h.

  14. For premenopausal women with childbearing potential, a pregnancy test must be performed within 7 days before the initiation of treatment, serum pregnancy must be negative, 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.

Any underlying pulmonary disease (e.g., pulmonary embolism, severe asthma, severe chronic obstructive pulmonary disease within 3 months before randomization), b. Restrictive lung disease.
  9. Patients with central nervous system (CNS) metastasis and/or carcinomatous meningitis (meningeal metastasis) (intracranial invasion of nasopharyngeal carcinoma was excluded).
