The meeting was requested by
The CRL cited GMP deficiencies at the Hengrui Pharma facility where camrelizumab is manufactured and incomplete Bioresearch Monitoring (BIMO) clinical inspections due to FDA travel restrictions. The FDA did not indicate any issues related to clinical data or with the manufacturing site for rivoceranib.
Prior to the Type A meeting, the FDA had accepted Hengrui Pharma's written responses to GMP deficiencies. During the meeting, the FDA confirmed resubmission can occur without delay. The FDA also confirmed BIMO inspections due to FDA travel restrictions may occur after resubmission.
'The most critical outcome from our discussion with the FDA is that resubmission of Elevar's NDA can occur without further remediation at the Hengrui manufacturing site,' commented Dr.
About Hepatocellular Carcinoma (HCC)
HCC is the most common type of primary liver cancer. It most frequently develops in people with chronic underlying liver inflammation which may be from viral and non-viral causes. HCC typically has a poor prognosis with limited treatment options and continues to be a diagnosis with an ongoing urgent medical need.
About CARES-310
CARES-310 (NCT03764293) was a randomized, open-label, international Phase 3 study, which included 543 patients with unresectable or metastatic HCC who had not received prior systemic therapy. Patients were randomized 1:1 to receive the combination of camrelizumab + rivoceranib or sorafenib (400 mg orally twice daily), a standard-of-care first-line multi-kinase inhibitor treatment for uHCC. Camrelizumab was administered intravenously (190 mg) every two weeks and rivoceranib was administered orally (250 mg) once daily. The study was conducted at 95 study sites across 13 countries/regions, in which systemic treatment for uHCC independent of etiology, rivoceranib plus camrelizumab demonstrated statistically significant and clinically meaningful prolonged overall survival and progression-free survival and improved overall response rate versus sorafenib. The co-primary endpoints were overall survival and progression-free survival. Secondary endpoints included objective response rate and duration of response.
About Camrelizumab
Camrelizumab (SHR-1210) is a humanized monoclonal antibody that binds to the programmed death-1 (PD-1) receptor. Blockade of the PD-1/PD-L1 signaling pathway is a therapeutic strategy showing success in a wide variety of solid and hematological cancers. Camrelizumab is developed by Hengrui Pharma and has been studied in more than 5,000 patients. Currently, 50 clinical trials are underway in a broad range of tumors (including liver cancer, lung cancer, gastric cancer, and breast cancer, etc.) and treatment settings. Camrelizumab, under the brand name AiRuiKa, is currently approved for eight indications in

About Rivoceranib
Rivoceranib, a small-molecule tyrosine kinase inhibitor (TKI), is a highly potent inhibitor of vascular endothelial growth factor receptor 2 (VEGFR-2), a primary pathway for tumor angiogenesis. VEGFR-2 inhibition is a clinically validated approach to limit tumor growth and disease progression. Rivoceranib is currently being studied as a monotherapy and in combination with chemotherapy and immunotherapy in various solid tumor indications. Ongoing clinical studies include uHCC (in combination with camrelizumab), gastric cancer (as a monotherapy and in combination with paclitaxel), adenoid cystic carcinoma (as a monotherapy) and colorectal cancer (in combination with Lonsurf). Rivoceranib was the first TKI approved in gastric cancer in
