About

This is an open-label, multi-center study to evaluate the efficacy and safety of SHR-1701 in combination with famitinib in subjects with metastatic or locally advanced solid tumor. There are two parts of the study: combinational therapy part and monotherapy part. Phase I of combinational therapy part is to determine the recommended dose for Phase II (RP2D) for famitinib in the combined regimen, then efficacy and safety of SHR-1701 plus famitinib (RP2D) will be further evaluated in the following Phase II in cohorts 1/2/3, with simon's two-stage design. Meanwhile, efficacy and safety of famitinib will also be assessed in cohorts 4/5 in the monotherapy part.

Enrollment: 222 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Phase I of combinational therapy part: Histologically proven metastatic or locally advanced solid tumors, for which no effective standard treatment exists or standard therapy has failed.

2. Phase II of combinational therapy part and monotherapy part: Histologically confirmed metastatic or locally advanced selected solid tumor types with 0-2 prior lines of systemic therapy.

   For cohorts 1 or 4, patients with biliary tract carcinoma failed to one prior systemic treatment. Patients with previous adjuvant/neo-adjuvant therapy completed within 6 months can be enrolled.

   For cohort 2, patients with clear-cell renal cell carcinoma (or predominantly clear-cell subtype with primary tumor resected) after failure of no more than first-line standard therapy; For cohorts 3 or 5, patients with hepatocellular carcinoma must have progressed on prior first- or second-line standard therapy; Child-Pugh Class A; BCLC stage B or C, and not suitable for surgical or local therapy.

3. Subjects are 18 years old or older when signing the informed consent and gender is not limited.

4. Life expectancy of at least 12 weeks.

5. Eastern Cooperative Group (ECOG) performance status of 0 to 1.

6. At least one measurable lesion according to RECIST version 1.1.

7. Tumor tissue must be available for biomarker analysis prior to the first dose of treatment, If not available, subjects can consult the investigator for enrollment agreement.

8. Adequate hematological, hepatic and renal function as defined in the protocol.

9. Subjects with HBV infection: HBV DNA<500 IU/mL or < 2500 copy/mL, must receive anti-HBV therapy.

10. Subjects with HCV-RNA(+) must receive antiviral therapy.

11. Able and willing to provide signed informed consent form, and able to comply with all procedures.

Other protocol defined inclusion criteria could apply.

Exclusion criteria

1. For cohorts 1 or 4: known ampullary cancer or mixed cancer (HCC-ICC).
2. For cohorts 3 or 5: known hepatocholangiocarcinoma, sarcomatoid HCC, mixed cell carcinoma and lamellar cell carcinoma; history of hepatic encephalopathy.
3. For subjects in combinational therapy part: prior treatment with any anti-PD-1/PD-L1, or anti-CTLA-4 agents (specifically targeting T-cell co-stimulation or checkpoint pathways), or TGF-β inhibitors.
4. For cohort 4: prior treatment with VEGFR directed therapies including famitinib.
5. Factors to affect oral administration.
6. Major surgery procedure within 28 days prior to the first dose of trial treatment (excluding prior diagnostic biopsy or PICC); anticancer treatment within 28 days before the first dose of trial treatment; subjects in combinational therapy part who have received systemic steroid therapy or any other form of immunosuppressive therapy within 14 days prior to the first dose of trial treatment should also be excluded.
7. Moderate-to-severe ascites with clinical symptoms.
8. Active or history of central nervous system metastases.
9. Known genetic or acquired hemorrhage or thrombotic tendency.
10. History of gastrointestinal hemorrhage within 6 months prior to the start of study treatment or clear tendency of gastrointestinal haemorrhage.

Other protocol defined exclusion criteria could apply.
