Bull points
- In the first quarter of 2026, XtemV delivered more than $145 million in net product sales, an increase of more than 85% year-over-year, reflecting consistent patient outcomes and expanding eye care physician, or ECP, utilization across their practices.
- Having spent time in the field and at several medical conferences over the past few months, I can tell you what we're hearing directly from ECPs. They describe Extenvi as one of the most impactful medicines they've ever used with consistent outcomes, clear utility across their practices, and broad access that is nearly universal.
- We are deliberately building Tarsus to create and lead new categories in iCare and beyond with the pipeline and playbook to do it repeatedly.
Bear points
- our base case is that we'd have to conduct a large vaccine like phase three, and that's something we'd have clarity around as we got ready for that and talk to potential partners.
