EXEL announced via press release the updated data from the STELLAR-303 trial evaluating

zanzalintinib in combination with atezolizumab versus regorafenib in patients with non-MSI-H/ Etzer Darout, PhD, MBA

non-dMMR colorectal cancer (CRC), in the subgroup of patients without liver metastases (NLM). +1 212 526 6940

The trial failed to meet the dual primary endpoint of OS in NLM patients, with an OS of 15.9 etzer.darout@barclays.com

months versus 12.7 months delivering a non-statistically significant p-value of 0.1185 and BCI, US

hazard ratio of 0.83. The update does not reflect a change in the mOS values for either arm from Lukas Shumway, PhD

what was previously reported at an interim analysis in October where OS in NLM patients was +1 212 526 7293

not statistically significant. lukas.shumway@barclays.com

Recall, the ITT population achieved an OS of 10.9 months versus 9.4 months for regorafenib, jordan.becker1@barclays.com
