Treatment with Cabometyx as second-line therapy for patients with advanced hepatocellular carcinoma who previously received Nexavar demonstrated superior progression-free survival and improved overall survival compared with Stivarga, according to a study presented at the International Liver Cancer Association 2019 meeting and a press release.

“Hepatocellular carcinoma is a devastating disease with only a few treatment options demonstrating survival benefits and many investigational drugs have failed to meet overall survival endpoints in clinical trials,” Katie Kelley, MD, study investigator from the University of California, San Francisco, said in the release. “[This] analysis brings further insight into the comparative effectiveness of the key second-line treatments for advanced hepatocellular carcinoma, particularly in relation to important endpoints like progression-free survival. These results may support clinicians in making informed treatment decisions in order to deliver optimal care for their patients.”

Kelly presented results from a matching-adjusted indirect comparison (MAIC) of Cabometyx (cabozantinib, Ipsen) vs. Stivarga (regorafenib, Bayer) for the second-line treatment after Nexavar (sorafenib, Bayer). Investigators used data from the phase 3 CELESTIAL and RESOURCE trials for the comparison.

In the CELESTIAL trial, cabozantinib improved median progression-free survival (5.2 vs. 1.9 months; 95% CI, 4-5.5) and median overall survival (10.2 vs. 8 months; 95% CI, 9.1-12) compared with placebo.

The comparison study matched patients by baseline characteristics including age, race, geographical region, Eastern Cooperative Oncology Group performance status, Child-Pugh class, duration of prior sorafenib treatment, extrahepatic disease, macrovascular invasion, etiology of HCC, and alpha-fetoprotein tumor marker levels. Results showed that cabozantinib improved progression-free survival (5.6 vs. 3.2 months; 95% CI, 4.9-7.26) and numerically improved median overall survival (11.4 vs. 10.8 months) compared with regorafenib.

“At Ipsen, our mission is to prolong and improve patients’ lives and health outcomes, and we acknowledge the importance of providing health care professionals with the best available evidence to achieve these goals for patients,” Yan Moore, MD, senior vice president and head of oncology therapeutic area at Ipsen, said in the release. “While alternative methodological approaches such as MAIC are not substitutes to evidence-based prospective clinical trials, it is important to recognize the need for further insights into the comparative effectiveness of current treatment approaches.” – by Talitha Bennett
