Famitinib Plus Anti-PD1 Therapy for Advanced Urinary System Tumor, Advanced Gynecological Tumors

Phase II multi-chort, adaptive two-stage, open label, nonrandomized study. The aim of our study is to evaluate the efficacy and safety of anti-PD-1 antibody SHR-1210(Camrelizumab) in combination with a small-molecule multikinase inhibitor Famitinib in subjects with advanced RCC/UC/CC/EC and recurrent OC.

chort1: Renal Cell Carcinoma (RCC) chort2: Urothelial Carcinoma(UC) chort3: Ovarian Cancer (OC) chort4: Cervical Cancer (CC) chort5: Endometrial Cancer (EC)

Stage 1: Approximately 110 participants will be recruited, 22 participants per chort; Stage 2: Approximately 55 participants will be recruited, 11 participants per chort, if more than 7（including 7） patients reached ORR in every chort ; Approximately 155 participants will be recruited, 21 participants per chort, if 3 ≤ patients \<7 patients reached ORR in every chort.

9. Male or Female patient of childbearing potential (entering the study after a menstrual period and who have a negative pregnancy test), who agrees to use two methods (one for the patient and one for the partner) of medically acceptable forms of contraception during the study and for 3 months after the last treatment intake.

3. Known history of hypersensitivity to other antibody formulation.
4. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 2 weeks prior to trial treatment.
5. Hypertension and unable to be controlled within normal level following treatment of anti-hypertension agents: systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥ 90 mmHg.
6. Clinically significant cardiovascular and cerebrovascular diseases, including but not limited to（1）Congestive heart failure (New York heart association (NYHA) class \> 2)；（2）unstable or severe angina; （3）myocardial infarction within 12 months before enrollment；（4） ventricular arrhythmia which need medical intervention.（5）QTc\>450ms（male）/QTc\>470ms (female)；
7. Coagulation abnormalities (INR\>2.0、PT\>16s), with bleeding tendency or are receiving thrombolytic or anticoagulant therapy.
8. Bleeding history, having bleeding event（≥3 Grade according CTCAE 4.0 ）within 4 weeks before screening.
9. Tumor invasion around major vessels shown by imaging, high risk of major vascular invasion leading to massive hemorrhage judged by investigators.
10. Previous Arterial/venous thrombosis events within 6 months.
11. Known hereditary or acquired bleeding and thrombosis tendency.
12. Proteinuria ≥ (++) and 24 hours total urine protein \> 1.0 g.
13. Prior chemotherapy, radiotherapy, surgery therapy within 4 weeks or palliative radiotherapy within 2 weeks or target therapy within 5 half-life of the drug before the study drug administration, or any unresolved AEs \> Common Terminology Criteria for Adverse Events (CTCAE) Grade 1.
