What does WILLIAM EDENFIELD research?

Dr. Edenfield studies advanced solid tumors, which are types of cancers that can be difficult to treat and include conditions like small cell lung cancer and breast cancer. He investigates different treatment methods, including new drugs and combinations of therapies, to see how they can improve patient care. For instance, he looks at drugs that can reduce the side effects of chemotherapy or improve treatment efficacy, often focusing on how these treatments impact patients' quality of life and overall health.

Key findings

  • In a study of 83 patients treated with BMS-986158, 43% experienced diarrhea, and 39% had low platelet counts, with some patients showing stable disease or partial response.
  • In patients taking trilaciclib prior to chemotherapy for small cell lung cancer, only 28.5% needed growth factors compared to 56.3% in the non-trilaciclib group.
  • Only 3% of patients treated with AMG 820 and pembrolizumab showed meaningful improvement, though 99% experienced side effects like fatigue.
  • Avelumab showed a 5.2% response rate in patients with triple-negative breast cancer, while overall only 3% responded positively.
  • In patients with advanced solid tumors and kidney issues, mild to moderate impairment had similar drug effectiveness to healthy patients, helping guide dosage adjustments.
