Cardiff Oncology Appoints Leila Alland, MD, as Interim Chief Medical Officer

Seasoned oncology executive brings extensive clinical development expertise and a track record of advancing innovative cancer therapies

SAN DIEGO, Oct. 27, 2026 (GLOBE NEWSWIRE) -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company targeting RAS-mutated cancer by leveraging PLK1 inhibition, today announced the appointment of Leila Alland, MD, as interim Chief Medical Officer. Dr. Alland is a seasoned biopharmaceutical executive who has led multiple oncology drug development programs. Dr. Alland succeeds Roger Sidhu, MD, who has stepped down from his role as Chief Medical Officer.

“We are pleased to welcome Leila as interim Chief Medical Officer,” said Mani Mohindru, PhD, President and Chief Executive Officer of Cardiff Oncology. “She brings a strong track record of leadership in advancing novel cancer therapies and is well-positioned to guide our clinical strategy as we enter a pivotal phase in clinical development. Our randomized Phase 2 trial in first line RAS-mutated metastatic colorectal cancer is still ongoing, and median PFS has not been reached in the onvansertib 30 mg plus FOLFIRI and bevacizumab arm, our proposed Phase 3 regimen. All patients remaining on trial have now been on treatment for more than 18 months. We are at a defining period for Cardiff as we prepare to initiate our registrational Phase 3 study in the first quarter of 2027. Leila’s expertise will be instrumental as we advance this program and also evaluate the broader potential of PLK1 inhibition in other cancers with few treatment options.”

“Despite advances in the treatment of metastatic colorectal cancer, significant unmet needs remain, particularly for patients with RAS-mutated disease,” said Dr. Alland. “I believe onvansertib's differentiated approach, which targets a key vulnerability of RAS-mutated tumors through PLK1 inhibition, holds significant promise for addressing these challenges and improving patient outcomes. I am excited to take on this role at such an important stage in its development and help translate that promise into meaningful clinical benefit for patients.”

Dr. Alland has served as Chief Medical Officer at several clinical-stage biotechnology companies, including PMV Pharma, a precision oncology company focused on p53; Affimed, an immuno-oncology company; and Tarveda Therapeutics, a company developing targeted drug conjugates. Previously, she held leadership positions at AstraZeneca, Bristol Myers Squibb, Novartis and Schering-Plough, where she contributed to the development and approvals of oncology therapies including Tagrisso^®, Opdivo^®, Tasigna^® and Caelyx^®. Dr. Alland currently serves on the Board of Directors of Abeona Therapeutics Inc.

Dr. Alland received her medical degree from New York University and her bachelor's degree from the University of Pennsylvania. She completed her pediatric training at The Children's Hospital of Philadelphia and her hematology/oncology training at Memorial Sloan Kettering Cancer Center. She previously served on the faculty of Albert Einstein College of Medicine, where she cared for children with cancer and conducted research focused on oncoproteins and epigenetics.
