Q: Can you walk us through the decision to move forward with the two Phase III studies in the earlier line PDAC, and what gives you conviction on the Phase III in the adjuvant setting? A: Based on the data reported in pancreatic cancer, particularly the monotherapy data, we have strong conviction to pursue the entire PDAC space across all lines of therapy. The adjuvant study, involving patients with resected disease, offers a significant opportunity for long-term clinical impact. The proof-of-concept is supported by second and third-line data shown previously with monotherapy.
Q: How does the frequency of RAS mutations differ in the adjuvant setting compared to advanced or metastatic disease? A: There is no evidence suggesting a different representation of RAS drivers in the adjuvant setting compared to other stages. Almost all pancreatic cancer patients have a RAS driver, and there's no reason to believe these patients would respond differently to daraxonrasib.
Q: Regarding the adjuvant setting for resectable PDAC, has the proportion of resectable cases been static, and what is the regulatory bar for registration? A: The proportion of resectable PDAC cases, about 15%, is not expected to change in the short term due to the lack of screening tests like those for breast or colon cancer. As for the regulatory bar, we haven't engaged with authorities yet, so we can't comment on that aspect.
Q: How do you balance moving quickly with ensuring you don't run redundant trials or set difficult bars for the best patient options? A: Our primary motivation is to serve patients swiftly. Given the competitive environment, we must move quickly to deliver against unmet needs. We prioritize based on data, but we won't hold off on Phase III trials as it could leave patients unserved and allow competition to set new bars.
Q: Can you provide more details on the first-line metastatic pancreatic cancer strategy and the role of zoldonrasib? A: We are evaluating chemotherapy combinations to support the third arm in the trial, focusing on safety. Zoldonrasib, a G12D selective inhibitor, is highly active and may follow a separate registration path. We are also evaluating its combination with daraxonrasib as a potential RAS(ON) doublet.
