HIF-2 Complex Dissociation, Target Inhibition, and Acquired Resistance with PT2385, a First-in-Class HIF-2 Inhibitor in Clear Cell Renal Cell Carcinoma Patients.

The heterodimeric transcription factor HIF-2 is arguably the most important driver of clear cell renal cell carcinoma (ccRCC). While considered undruggable, structural analyses at UT Southwestern Medical Center (UTSW) identified a vulnerability in the a subunit, which heterodimerizes with HIF-1b, ultimately leading to the development of PT2385, a first-in-class inhibitor.

A Pilot Study of Radiation Therapy in Combination With Pembrolizumab in Patients With Metastatic Renal Cell Cancer.

There is no study published regarding the benefit of radiation therapy (RT) in combination with immune checkpoint inhibitors (ICIs) for the treatment of metastatic renal cell cancer (mRCC). This report is part of an exploratory study aiming to determine the immunomodulatory activity of RT alone or in combination with pembrolizumab in solid tumors.
