Exploratory Clinical Study of Apatinib and SHR-1210 in Treating Advanced Hepatocellular Carcinoma or Gastric Cancer

Phase 1

• Conditions: Hepatocellular Carcinoma; Gastric Cancer
• Interventions: Drug: apatinib; Drug: SHR-1210

• Registration Number: NCT02942329
• Lead Sponsor: The Affiliated Hospital of the Chinese Academy of Military Medical Sciences

Brief Summary

The purpose of this study is to observe and preliminary explore the efficacy and safety of combination of Apatinib and SHR-1210 regimen in treating advanced hepatocellular carcinoma or gastric cancer.

Apatinib is a small-molecule vascular endothelial growth factors receptor (VEGFR) tyrosine kinase inhibitor, similar to vatalanib (PTK787), but with a binding affinity 10 times that of vatalanib or sorafenib.

SHR-1210 is a humanized anti-PD-1 monoclonal antibody.

Detailed Description

Patients will received apatinib orally every day and SHR-1210 200mg (3mg/kg for underweight patients) iv every 2 weeks. The efficacy and safety will be observed.

The dose escalation phase has completed for apatinib from 125mg, 250mg to 500mg. The dose of 250mg showed best tolerance and efficacy especially in hepatocellular carcinoma. Thus, for hepatocellular carcinoma patients, apatinib 250mg orally every day was chosed for the dose extension phase. In gastric cancer, the dose of 250mg also showed good tolerance but mild efficacy. Thus, for gastric cancer patients, the dose of 375mg daily for apatinib would be explored and then the investigators will decide the best dosage for these patients.

Inclusion Criteria

Inclusion criteria

1. Aged 18-70 years old, both genders.
2. To be confirmed to meet the clinical diagnosis standard, histologically or cytologically confirmed with hepatocellular carcinoma or gastric cancer. Patients must be diagnosed with advanced disease(not eligible for surgical and/or locoregional therapies, or metastatic disease), disease progressed or refractory to standard therapies(had been intolerant to standard therapies, or had refused standard therapy), or lack of other effective treatment methods.
3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1.
4. Life expectancy of at least 3 months.
5. Patients must have at least 1 lesion that is measurable using RECIST v1.1 criteria.
6. For patients with advanced hepatocellular carcinoma, liver function status Child-Pugh Class A or B (score<=7).
7. Patients must have adequate organ function (without blood transfusion, without growth factor or blood components support within 14 days before enrollment)as determined by: Hemoglobin ≥ 9 g/dL; Absolute neutrophil count (ANC) ≥1.5×109/L; Platelet count ≥ 75×109/L (for patients with advanced hepatocellular carcinoma), Platelet count ≥ 100×109/L (for patients with advanced gastric cancer); serum albumin ≥2.8 g/dL; serum total bilirubin (TBIL)≤1.5 times the upper limit of normal (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5×upper limit of normal(ULN), for subjects with liver metastases, ALT and AST≤5×ULN; Calculated creatinine clearance (CrCl) > 50 mL/min (Cockcroft-Gault formula will be used to calculate CrCl).
8. Females of childbearing potential (FOCBP), who are not surgically sterile or postmenopausal, must conduct pregnancy test (serum or urine) within 7 days before enrollment, and must not be pregnant or breast-feeding women. If the result is negative, she must agree to use adequate contraception during the experiment and 3 months after the last administration of the test drugs. And non-sterilized males who are sexually active must agree to use adequate contraception during the experiment and 3 months after the last administration of the test drugs.
9. Patients join the study voluntarily, sign a consent form, have good compliance, and comply with follow-up.

Exclusion Criteria

1. Patients must not have had prior treatment with SHR-1210 or any other PD-L1 or PD-1 antagonists, and must not have had be enrolled in the phase III Study of Apatinib After Systemic Therapy in Patients With Hepatocellular Carcinoma.
2. Patients with any active autoimmune disease or history of autoimmune disease, including but not limited to the following: hepatitis, pneumonitis, uveitis, colitis (inflammatory bowel disease), hypophysitis, vasculitis, nephritis, hyperthyroidism, and hypothyroidism, except for subjects with vitiligo or resolved childhood asthma/atopy. Asthma that requires intermittent use of bronchodilators or other medical intervention should also be excluded.
3. Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids. Doses > 10 mg/day prednisone or equivalent are prohibited within 2 weeks before study drug administration. Note: corticosteroids used for the purpose of IV contrast allergy prophylaxis are allowed.
