RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:My opinionThe extension of PFS to 27 months is impressive. This is 2L and HER2+ breast cancer is about 20% of cases.
Great news for patients. It seems it's becoming the standard for HER2+. Given the targeting issues, I guess Enhertu will only work for the HER2+ subset so may not be useful for THTX to attach for all solid tumors in 4L setting. But those numbers would be something to shoot for!

The FDA has granted breakthrough designation to AstraZeneca's and Daiichi Sankyo's HER2 ADC Enhertu, the companies jointly announced today.
The BTD is for the treatment of adult patients with unresectable or metastatic HER2 positive breast cancer who have received one or more prior anti-HER2-based regimens.
Breakthrough therapy designation was based on data from the DESTINY-Breast03 pivotal trial at #ESMO21 just last month, which showed a 72% reduction compared to Roche’s ADC Kadcyla in the risk of disease progression or death in patients with HER2 positive unresectable and/or metastatic breast cancer previously treated with trastuzumab and a taxane.
“This is an important step in bringing Enhertu as a potential new option in earlier lines of treatment for HER2 positive metastatic breast cancer, given the urgent need to improve outcomes,” said AstraZeneca EVP of oncology R&D Susan Galbraith in a statement.
Previous BTDs for the drug were in late-line HER2 positive metastatic breast cancer in 2017 and HER2 mutant metastatic non-small cell lung cancer (NSCLC) and HER2 positive metastatic gastric cancer in 2020."
