Under the terms of the agreement, Elevar will pay Hengrui Pharma up to $600 million of sales milestones and a double-digit percentage royalty on camrelizumab net sales.
In May 2023, a biologics license application (BLA) for camrelizumab and a new drug application (NDA) for rivoceranib were submitted to the U.S. Food and Drug Administration (FDA) for the combination of camrelizumab and rivoceranib as a first-line therapy for uHCC. The FDA accepted the submissions, assigning Prescription Drug User Fee Act (PDUFA) target action dates in May 2024.
Rivoceranib, under the name apatinib (brand name: Aitan®), is developed by Hengrui Pharma in China. In January 2023, the combination was approved in China as a first-line treatment for uHCC. Elevar maintains development rights to rivoceranib outside of China and Korea.
Hengrui Pharma has 13 in-house-developed innovative products and two in-licensed innovative products marketed in China, more than 80 proprietary innovative candidates in the R&D stage and nearly 20 under clinical development worldwide. The company has also demonstrated a clear commitment to HCC patients globally, as its initial efforts in China led to the 2020 approval of apatinib as a single agent for second-line treatment for advanced HCC.
Elevar and Hengrui Pharma presented CARES-310 study results at the September 2022 ESMO Congress and published them in The Lancet on July 24, 2023. Camrelizumab plus rivoceranib significantly prolonged overall survival and progression-free survival, and increased overall response rate versus sorafenib, a standard first-line treatment for uHCC.
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 China (2014). It is also approved in China as a single agent for a second-line treatment for advanced HCC (2020) and in combination with camrelizumab for a first-line treatment for uHCC (2023). The drug has been studied in more than 6,000 patients worldwide and was well tolerated in clinical trials with a comparable safety profile to other TKIs and VEGF inhibitors. Orphan drug designations have been granted in gastric cancer (U.S., EU and South Korea), in adenoid cystic carcinoma (U.S.) and in uHCC (U.S.).
