SHR-1210 in Combination With Anlotinib in Patients With Advanced or Metastatic Esophageal Squamous Cell Cancer

Phase 2

• Conditions: SHR-1210; Anlotinib; Advanced Esophageal Squamous Cell Cancer
• Interventions: Drug: SHR-1210 plus Anlotinib

• Registration Number: NCT04797507
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

This study was designed to explore the clinical efficacy of SHR-1210 in combined with Anlotinib in the treatment of second- or above- line advanced or metastatic esophageal squamous cell cancer patients, in order to find a better therapy strategy for esophageal squamous cell cancer patients.

Detailed Description

This is a prospective, phase II, single-arm clinical trial. Advanced or metastatic esophageal squamous cell cancer(ESCC) patients progressed after 1st systematic treatment are treated with SHR-1210 and Anlotinib. SHR-1210 was given intravenously(200mg d1 Q2w), combined with Anlotinib orally, 12 mg d1-14 Q3w. The hypothesis: The objective response rate in SHR-1210 combined with Anlotinib can reach 40% as second-line or above treatment of advanced or metastatic ESCC patients. The primary endpoint is objective response rate (ORR) and the secondary endpoint is disease control rate (DCR), overall survival (OS), progression-free survival (PFS), and safety of this regimen.

Exclusion Criteria

Patients should not be selected for this clinical study if they have any of the following conditions:

1. Abnormal coagulation function , with bleeding tendency or receiving thrombolytic or anticoagulant therapy. Note: Low-dose heparin (60,000-12,000 U/day for adults) or low-dose aspirin (≤100mg/day) are permitted for prophylactic purposes if INR≤1.5.
2. The arterial/venous thrombosis events, such as cerebrovascular accidents (including transient ischemic attack, cerebral hemorrhage, cerebral infarction), deep venous thrombosis, pulmonary embolism, etc, occurred within 6 months before administration.
3. Clinically significant hemoptysis occurred within 3 months before medication (hemoptysis > 50ml per day); Or clinically significant bleeding symptoms or definite bleeding tendency, such as gastrointestinal bleeding, bleeding gastric ulcer, baseline fecal occult blood ++ or above, or vasculitis, etc.
4. Subjects with any active, known or suspected autoimmune disease or history of autoimmune disease.
5. Received systemic steroid therapy within 3 days of the first dose of study medication.
6. Received a live vaccine within 4 weeks of the first dose of study medication.
7. Major surgery received or severe traumatic injury, fracture, or ulcer occurred within 4 weeks of the first dose of study medication.
8. Imaging (CT or MRI) showed that the distance of the tumor lesion from great vessels was less than 5 mm, or invasion of local great vessels, or central tumor with high blood risk; Or there is obvious lung cavity or necrotizing tumor. Uncontrolled clinically significant systemic diseases, including active infection, unstable angina, angina occurred within 3 months,≥ NYHA II congestive heart failure, myocardial infarction occurred within 6 months, severe arrhythmia, liver, kidney, or metabolic disease.
