Study Groups

Treatment Arm

Group Type: EXPERIMENTAL

Toripalimab plus Nab-Paclitaxel +/- cisplatin

Intervention Type: DRUG

Toripalimab injection (JS001): 240mg, i.v.gtt, q3w; Nab-Paclitaxel: 260mg/m2, i.v.gtt, q3w Cisplatin: total dosage of 70 mg/m2 i.v.gtt, q3w，, complete all doses within the first 2 days of each cycle.

Study treatment will be continued until disease progression or intolerable toxicity, or withdrawal at the discretion of the investigator or the subject, loss to follow-up, or initiation of other anti-cancer therapy, or death, whichever occurs first. Toripalimab will be administered no more than 2 years,and nab-paclitaxel with or without cisplatin will be administered up to 6 cycles.. If the subject is intolerable to cisplatin treatment according to the investigator's judgment, JS001 + Nab-Paclitaxel may be dosed.

Eligibility Criteria

Inclusion Criteria

1. Fully understand the study and are willing to sign informed consent form (ICF);

2. Age of ≥ 18 years at screening, male or female;

4. Not previously treated with systemic chemotherapy; Patients with urothelial carcinoma who have received prior adjuvant or neoadjuvant treatment or radiochemotherapy are eligible, provided that progression has occurred >6 months from last therapy (for radiochemotherapy and adjuvant treatment) or >6 months from last surgery (for neoadjuvant treatment).

5. At least 1 measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1;

6. Providing tissue specimen for PD-L1 testing and related pathological report prior to enrollment for biomarker evaluation (tumor tissue specimen must be freshly obtained or archived within 3 months prior to enrollment; the fresh tissue must be a biopsy specimen of hollow needle punctured, excisedor resected);

7. ECOG performance status score of 0 or 1;

8. Life expectancy ≥ 12 weeks in the Investigator's opinion;

9. Adequate organ function:

Coagulation function: international normalized ratio (INR) or prothrombin time (PT), activated partial thromboplastin time (aPTT) ≤1.5 × ULN (unless the subject is receiving anticoagulation therapy, PT or aPTT just needs to be within the expected therapeutic range of the anticoagulant).

10. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests and other study procedures.

11. Men of reproduction ability or women of pregnant possibility [amputation of uterus, bilateral oophorectomy or bilateral tubal ligation not performed, or prior to menopause (total menopause ≥1 year)] must adopt highly-effective contraceptive methods (e.g. oral contraceptives, intrauterine contraceptive device, abstinence of sexual intercourse or barrier contraception in combination with spermatocide) during the whole study, and continue contraception for 12 months after the last dose of study drug.

Exclusion Criteria

1. Prior exposure to immune-mediated therapy (with the exclusion of Bacillus Calmette Guerin, BCG), including but not limited to, other anti-CTLA-4, anti-PD-1, anti-PD-L1, or anti-PD-L2 antibodies, including therapeutic anticancer vaccines;

Patients who have prior therapies for brain or meningeal metastasis and has been stabilized for ≥ 3 months and has discontinued systemic steroids therapy (>10 mg/day prednisone or equivalent) > 4 weeks prior to enrollment could be included. If the CNS metastasis can be adequately treated and meet the requirement specified in the enrollment criteria, and the neurological symptoms can be recovered to ≤CTCAE grade 1 prior to enrollment (except the residual sign or symptom related with CNS treatment) for at least two weeks, the subject can participate in the study;

15. Active or previously recorded autoimmune or inflammatory diseases (including inflammatory bowel disease, systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, etc.) within 2 years prior to enrollment. The following are exceptions to this criterion:

Patients with vitiligo or alopecia; Patients with a history of autoimmune-related hypothyroidism on a stable dose of thyroid-replacement hormone (eg, treated Hashimoto's syndrome) or patients with psoriasis requiring no systemic treatment;

17. Pregnant or lactating women;

18. Previously received allogeneic hematopoietic stem cell transplantation or solid organ transplantation;
