Howard A Burris

Medical oncologist who led the Sarah Cannon Research Institute in Nashville as President and Chief Medical Officer, has run hundreds of early-phase cancer drug trials, including the first trial of the mTORC1-selective inhibitor RMC-5552, and was ASCO President in 2019–2020

President and Chief Medical Officer, Sarah Cannon Research Institute, Nashville (retirement from this role announced for end of 2025, advisory role after) · at Sarah Cannon since 1997 · President, American Society of Clinical Oncology (2019–2020) · earlier Director of Clinical Research, Institute for Drug Development, San Antonio · U.S. Army physician, Brooke Army Medical Center (service ended 1997)

Howard A Burris Portrait: ASCO Connection

Howard Burris is a co-author of two Atlas trial papers about mTOR drugs in cancer. PIC2014 is the final report of BOLERO-2, which added everolimus, a rapamycin-like mTORC1 blocker, to the hormone drug exemestane in women with advanced hormone-receptor-positive breast cancer. The combination kept the cancer in check for longer (7.8 against 3.2 months) but did not significantly lengthen overall survival. SCH2025 was the first trial in patients of RMC-5552, a newer bi-steric drug designed to block mTORC1 fully while sparing mTORC2. In 57 patients with advanced solid tumours, high blood sugar, a typical side effect of older mTOR drugs, was uncommon (4 percent). Without a comparison group, the trial is an early signal, not proof.

Burris joined the Sarah Cannon Research Institute in Nashville in 1997. It became one of the largest centres in the United States for early-phase (phase 1) cancer trials, where new drugs are first given to patients to find a safe dose. PubMed lists him with a Sarah Cannon affiliation on more than 200 trial papers, which shows how many new cancer drugs pass through this kind of centre on the way to approval.

Burris studied at the U.S. Military Academy at West Point and at the University of South Alabama College of Medicine. He served as an Army doctor, finishing his service at Brooke Army Medical Center in San Antonio in 1997, and before that directed clinical research at the Institute for Drug Development in San Antonio. At Sarah Cannon he became Chief Medical Officer and Executive Director of the Drug Development Program, and later President and Chief Medical Officer. He was President of the American Society of Clinical Oncology (ASCO) for 2019 to 2020. In October 2025 Sarah Cannon announced that he would retire from the President and Chief Medical Officer role at the end of 2025 and stay on as an adviser.
