Question · Q4 2025
Yi Chen of H.C. Wainwright & Co. requested clarification on the specific clinical milestones for MDX-2001 and MDX-2004 in 2026. He also questioned the BioReference margin expansion and expense bridge, seeking more color on why the total expense guidance of $725 million-$750 million seemed high following the divestiture.
Answer
Dr. Elias Zerhouni, Vice Chairman and President, outlined MDX-2001's milestone as completion of dose regimen and entry into Phase 1B, and MDX-2004's as Phase 1 escalation with Phase 1A completion this year. Adam Logal, SVP and CFO, explained that while BioReference expenses are declining, the overall expense expansion is driven by increased R&D investments, with other operating costs expected to stabilize or reduce.
