Spotlighting Key Upcoming Presentations Across Oncology at ASCO 2025

Ahead of the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, CancerNetwork® spoke with a variety of oncology experts about the late-breaking abstracts, plenary sessions, and other key presentations that may shift the paradigm across different cancer care fields. They highlighted anticipated clinical trial results that may transform the standard of care for gynecologic malignancies, lung cancer, and other disease types.

Rachel N. Grisham, MD, section head of Ovarian Cancer and director of Gynecologic Medical Oncology at MSK Westchester of Memorial Sloan Kettering Cancer Center, shared her anticipation of findings from the phase 3 ROSELLA trial (NCT05257408) assessing relacorilant plus nab-paclitaxel in patients with platinum-resistant ovarian cancer. She stated she was excited to see if the data may represent a new opportunity for this patient population.

Next, MinhTri Nguyen, MD, a medical oncologist and hematologist at Stanford Health Care, highlighted a few breast cancer presentations to look out for. These topics included a plenary session on data from the phase 3 SERENA-6 study (NCT04964934) evaluating camizestrant in combination with CDK4/6 inhibitors for those with hormone receptor–positive, HER2-negative advanced breast cancer harboring emergent ESR1 mutations.

Additionally, Eric K. Singhi, MD, assistant professor in the Department of General Oncology in the Division of Cancer Medicine, and assistant professor in the Department of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center, spoke about a range of potentially practice-changing results in the lung cancer field. For example, he described a session focused on primary results of the phase 3 IMforte trial (NCT05091567) assessing lurbinectedin (Zepzelca) plus atezolizumab (Tecentriq) for those with extensive-stage small cell lung cancer (ES-SCLC). According to Singhi, data from IMforte may shift the paradigm of maintenance therapy for this SCLC population.

In the world of head and neck cancer, Douglas R. Adkins, MD, associate professor of Internal Medicine, Division of Oncology, Section of Medical Oncology at Washington University School of Medicine in St. Louis, Missouri, highlighted the session on the phase 3 NIVOPOSTOP GORTEC 2018-01 trial (NCT03576417). Investigators of this study evaluated nivolumab (Opdivo) in combination with chemoradiotherapy for those with resected head and neck squamous cell carcinoma. Adkins noted his excitement to see how these data may impact the standard of care, particularly for patients in Europe, where investigators conducted the study.

As part of an Oncology Decoded discussion, Benjamin Garmezy, MD, the associate director of genitourinary research and executive cochair of the Genitourinary Cancer Research Executive Committee at Sarah Cannon Research Institute (SCRI) and medical oncologist at SCRI Oncology Partners specializing in genitourinary cancers, discussed key abstracts in bladder cancer. One specific presentation included additional findings from the phase 3 NIAGARA trial (NCT03732677), which may show how circulating tumor DNA can influence treatment decision-making regarding perioperative durvalumab (Imfinzi) for patients with muscle-invasive bladder cancer.
