Top-line findings will be presented Sept. 10 at the annual European Society for Medical Oncology (ESMO) Congress

  • This is the first positive pivotal trial to show survival benefits with a PD-1 inhibitor plus an anti-angiogenic TKI for uHCC

  • Sorafenib is a standard first-line treatment for uHCC

PARIS, Sept. 07, 2022 (GLOBE NEWSWIRE) -- Elevar Therapeutics, Inc., a fully integrated biopharmaceutical company dedicated to elevating treatment experiences and outcomes for patients who have limited or inadequate therapeutic options, today announced top-line results from the Phase 3 study of its drug candidate rivoceranib combined with camrelizumab versus sorafenib as a first-line therapy for unresectable hepatocellular carcinoma (uHCC). Camrelizumab plus rivoceranib significantly prolonged overall survival (OS) and progression-free survival (PFS), and improved overall response rate (ORR) versus sorafenib, a standard first-line treatment for uHCC. The findings will be presented Sept. 10 during the annual Congress of the European Society for Medical Oncology (ESMO) in Paris.

“Camrelizumab (C) plus rivoceranib (R) vs. sorafenib (S) as first-line therapy for unresectable hepatocellular carcinoma (uHCC): a randomized, Phase 3 trial,” will be shared as a late-breaking proffered paper presentation at ESMO on Sept. 10, 8:40 a.m. – 8:50 a.m. CEST, location 7.1C – Cannes Auditorium. The session title is: Proffered Paper Session 1: GI, upper digestive.

The global, randomized, open-label trial (NCT03764293) included 543 patients (ITT population). The study began in June 2019, reaching its primary endpoint in April 2022. Top-line data included:

  • Median OS for camrelizumab+rivoceranib was 22.1 mos. [95% CI 19.1-27.2] vs. 15.2 mos. [13.0-18.5]; hazard ratio (HR) 0.62 [95% CI 0.49-0.80]; 1-sided p<0.0001,

  • Median PFS for camrelizumab+rivoceranib was 5.6 mos. [95% CI 5.5-6.3] vs. 3.7 mos. [2.8-3.7]; HR 0.52 [95% CI 0.41-0.65]); 1-sided p<0.0001, and

  • Confirmed ORR for camrelizumab+rivoceranib was 25.4% (95% CI 20.3-31.0), compared to 5.9% (3.4-9.4) for sorafenib.

“This study marks the first positive pivotal trial to show survival benefits with an anti-angiogenic TKI plus a PD-1 inhibitor for unresectable hepatocellular carcinoma,” said Jan M. Van Tornout, M.D., MSc., chief medical officer of Elevar. “The efficacy results demonstrate that camrelizumab plus rivoceranib present as a new first-line treatment option for uHCC. We look forward to detailing additional findings, including results within Asian and non-Asian populations, shortly after our presentation at ESMO.”

About Hepatocellular Carcinoma (HCC)

HCC is the most common type of primary liver cancer. It most frequently occurs in people with chronic liver diseases, such as cirrhosis caused by hepatitis B or hepatitis C infection. HCC typically has a poor prognosis and a lack of treatment options and is therefore a condition with an urgent medical need.

About Camrelizumab
Camrelizumab (SHR-1210) is a humanized monoclonal antibody targeting 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 et. all) and treatment settings.

Camrelizumab, under the brand name AiRuiKa®, is currently approved for 8 indications in China, including monotherapy for the treatment of HCC (second-line), relapsed/refractory classic Hodgkin’s lymphoma (third-line), esophageal squamous cell carcinoma (second-line) and nasopharyngeal carcinoma (third-line or further) and in combination with chemotherapy for the treatment of non-small cell lung cancer (non-squamous and squamous), esophageal squamous cell carcinoma, and nasopharyngeal carcinoma in the first-line setting. The U.S. Food and Drug Administration granted Orphan Drug Designation to camrelizumab for advanced HCC in April 2021.

About Rivoceranib
Rivoceranib is the first small-molecule tyrosine kinase inhibitor (TKI) approved in gastric cancer in China (November 2014). Rivoceranib 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 co-developed by Hengrui Pharmain China and by Elevar Therapeutics, Inc. globally (excluding China). It 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. Rivoceranib is currently being studied as a monotherapy and in combination with chemotherapy and immunotherapy in various solid tumor indications. Clinical studies are ongoing in multiple solid tumor types including gastric cancer (as a monotherapy and in combination with paclitaxel), hepatocellular carcinoma (HCC) (in combination with camrelizumab), adenoid cystic carcinoma (as monotherapy) and colorectal cancer (in combination with Lonsurf®). Orphan drug designations have been granted in gastric cancer (U.S., EU and South Korea), in adenoid cystic carcinoma (U.S.) and in HCC (U.S.). Elevar holds the global rights (excluding China) and has partnered for the development and marketing of rivoceranib with HLB-LS in South Korea. Rivoceranib, under the name apatinib, is currently approved in China for advanced gastric cancer and in second-line advanced HCC by the Chinese-territory license-holder, Hengrui Pharma, under the brand name Aitan®.

It has been granted orphan drug designation in the U.S., Europe and South Korea and has been clinically tested in more than 1,000 patients worldwide in numerous cancer indications. Apealea® is a non-Cremophor EL based formulation of paclitaxel that received marketing authorization by the European Commission in November 2018, making it Europe’s first non-Cremophor EL formulation of paclitaxel approved for use in ovarian cancer.
