ctDNA reduction at week nine in patients treated with tebentafusp was associated with improved overall survival
AUSTIN, Texas, Nov. 21, 2022 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced the publication of a new study in Nature Medicine, which shows that its mPCR technology is able to assess response to tebentafusp in treatment-refractory metastatic uveal melanoma. The findings indicated an association between early reductions in ctDNA and longer overall survival, suggesting that traditional radiographic-based response criteria don't accurately reflect tebentafusp-related clinical activity and benefit. The full study can be found here.
The study reports results from a multi-center, single-arm, open-label phase 2 study of tebentafusp in 127 patients with previously treated metastatic uveal melanoma – an aggressive, but rare, cancer of the eye. Despite an overall response rate of 5%, the median overall survival (16.8 months) was more than double that of previous studies,1 suggesting the need for additional tools to help predict outcomes.
Key takeaways from the study include:
"We're excited to see another study showing the potential for ctDNA-based technology to monitor immunotherapy response," said Minetta Liu, M.D., chief medical officer of oncology at Natera. "This study redemonstrates the broad utility of ctDNA as a reliable pan-cancer biomarker of disease status."
