• Key programs include:
  • Vudalimab: Advancements in prostate cancer and initiation of a front-line lung cancer trial.
  • XmAb819: Targeting ENPP3 in renal cell carcinoma, currently in Phase 1 dose escalation.
  • XmAb808: A CD28 bispecific targeting B7-H3, also in Phase 1.
  • XmAb541: Targeting CLDN6, expected to enter the clinic soon.

4. Bad News, Challenges, or Points of Concern

• A notable safety concern arose with vudalimab, which reported one case of Grade 5 immune-related hepatitis among over 240 treated patients. This incident raised questions about the management of autoimmune adverse events.
• The decision to pause the XmAb564 study was strategic, driven by a focus on T-cell engagers rather than data-driven concerns.
• The competitive landscape remains challenging, with emerging therapies like PLUVICTO potentially impacting future treatment paradigms.

5. Notable Q&A Insights

• Management was cautious about providing specific timelines for data release from ongoing studies, particularly for XmAb819.
• The company is comparing vudalimab's efficacy against historical benchmarks, particularly focusing on response rates in heavily pretreated patient populations.
