Details and patient eligibility


This is a phase II trial to evaluate the efficacy and safety of immune checkpoint inhibitors in combination with axitinib for previously treated advanced collecting duct carcinoma.

Full description

Patients meeting specific inclusion and exclusion criteria will be enrolled in two stages, 8 patients in stage 1 and 22 patients in stage 2. Stage 2 will enroll if 1 or more patients exhibit a response at week 9 or later in stage 1 in the study. All enrolled patients will be treated with immune checkpoint inhibitors in combination with axitinib until disease progression. Efficacy will be assessed by tumor measurements using CT and MRI (when indicated) scans and physical exam at baseline, and scans and physical exam of all disease-involved areas every 9 weeks until progression. Safety will be assessed by periodic physical exams, clinical laboratory studies, and adverse events. All patients will have a follow-up visit 90 days following last study drug treatment.

  7. Being willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures.

  8. Female subjects of childbearing potential must have a negative serum pregnancy test within 7 days prior to the first treatment dose. Female subjects of childbearing potential and male subjects whose partners are of childbearing potential must agree to use a highly effective methods of contraceptive throughout the study and for 180 days after the last dose of study therapy.

Exclusion Criteria: Exclusion criteria: Patients with any of the following conditions will not be included in the study:

  1. Prior Anti-PD-1, PD-L1 or axitinib.

  2. Has participated or is currently participating in a trial of investigational agent within 4 weeks prior to the first dose of study treatment, unless observational (non-interventional) clinical study or follow-up period of interventional study.

  3. Had major surgery (judged by investigators) within 4 weeks prior to the first dose of study treatment or has not recovered from prior surgery.

  4. Has traditional Chinese medicine or Chinese patent medicine preparation with anti-cancer indication within 2 weeks prior to the first dose of study treatment.

  5. Requiring corticosteroids (Prednisone >10 mg/day or equivalent analogue) or other immunosuppressive agents within 2 weeks prior to the first dose of study treatment. 6. Patients without active autoimmune disease using inhaled prednisone >10 mg/day will not be excluded from the study.

  6. Has a history of organ transplantation or required long-term treatment with corticosteroids.

  7. Hypothyroidism, hypoadrenalism or hypopituitarism that can be controlled only with hormone replacement therapy, type I diabetes, psoriasis or leucoderma not requiring systematic treatment.

  8. Not recovered from the toxicity of prior anti-cancer therapy, i.e., not recovered to baseline, Grade 0-1 (NCI-CTCAE 5.0, except alopecia) or per inclusion/exclusion criteria in protocol. Under rational expectation, irreversible toxicities (e.g., hearing loss) which will not be worsened by study treatments may be enrolled in the study.

  9. Has an additional malignancy that has progressed or required treatment within 5 years prior to randomization (basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, or carcinoma in situ such as breast cancer, prostate cancer are acceptable if they have undergone potentially curative therapy;Remarks: Localized low-risk prostate cancer [ patietns with stage ≤ T2a, Gleason score ≤ 6 and PSA < 10ng/mL at the time of diagnosis (as measured) can be included in this study if the subject has received radical therapy and has no evidence for biochemical recurrence(PROSTATE specific antigen,PSA)].

Subjects may participate in the study if their CNS metastases are adequately treated to meet the requirements specified in the inclusion criteria, and their neurological symptoms recover to grade 0-1 (CTCAE 5.0) for at least 2 weeks prior to inclusion (except for residual signs or symptoms associated with CNS treatment).
