    Question

    Tejas Wein, on behalf of Ellie Merle at UBS, inquired if PTC has received any anecdotal coverage approvals for Sefiance yet. He also asked about the distribution of PKU patients in ex-US countries, specifically whether they are concentrated in major centers or more spread out.

He used Germany as an example, where their compassionate use program targeted centers overseeing nearly 8,000 patients, indicating a centralized care model.

    Ellie Merle's questions to Revolution Medicines (RVMD) leadership • Q2 2025

    Question

    Ellie Merle from UBS inquired about Revolution Medicines' perspective on RAF upregulation as a resistance mechanism to RAS inhibitors and the company's thoughts on RAF degradation versus inhibition, particularly in the G12D cancer space.

    Answer

    President of R&D Steve Kelsey acknowledged that amplification of the mutant RAS allele is a major escape mechanism, particularly for multi-selective inhibitors, but noted it can be overcome therapeutically, for instance with a RAS-ON doublet. He stated there is currently no evidence that a degrader is superior to an inhibitor for any oncology target, pending clinical data from degrader companies. CEO Mark Goldsmith added that this resistance mechanism validates the effectiveness of diraxonrasib.

He expressed confidence that efficacy will translate to the first-line setting as RAS is a fundamental driver across lines of therapy.

    Question

    Ellie Merle of UBS asked about the changes in expectations for the ex-U.S. launch cadence of Pombiliti/Opfolda and how much this, along with the situation in the Netherlands, contributed to the revised guidance.

    Answer

    President and CEO Bradley Campbell attributed the guidance change to two main factors: a timing delay in patient starts in newly reimbursed countries shifting from Q1 to later in the year, and the unexpected impact of the U.K.'s VPAG rebate. He noted the Netherlands is a significant opportunity with over 150 patients, but uptake is slowed by a single-center treatment bottleneck, with growth expected in the second half of the year.
