** Main Story**

MD Anderson Cancer Center researchers made a significant impact at the American Association for Cancer Research (AACR) Annual Meeting 2025, held from April 25-30 in Chicago. The team presented over 200 studies, highlighting promising clinical trial results and groundbreaking research across various cancer types. This article delves into the key findings presented, focusing on three clinical trials and other notable advancements.

Personalized Vaccine and Radiotherapy Advancements

Colorectal Cancer Vaccine

A personalized vaccine combination therapy for colorectal cancer showed promising results in a Phase I feasibility study. Researchers developed the NeoAg-VAX platform, which utilizes bioinformatics and sequencing to create personalized vaccines targeting each patient’s unique tumor mutations. The vaccine, combined with or without pembrolizumab immunotherapy, proved safe and feasible in 28 patients with microsatellite-stable metastatic colorectal cancer (MSS mCRC). The vaccine triggered robust immune responses and provided valuable insights into the tumor microenvironment, potentially informing future treatment strategies.

Kidney Cancer Radiotherapy

Researchers explored the use of metastasis-directed radiation therapy to mitigate the toxicities associated with systemic treatments for kidney cancer. In a prospective Phase II trial involving 121 patients with oligometastatic clear cell renal cell carcinoma (ccRCC), the median progression-free survival reached 18 months, and the median systemic therapy-free survival was 34 months. Remarkably, overall survival remained uncompromised, with rates of 94% and 87% at two and three years, respectively. A novel circulating tumor DNA (ctDNA) assay also showed promise in detecting molecular residual disease, potentially guiding treatment decisions.

Pancreatic Cancer Exosomes

Engineered exosomes designed to silence mutant KRAS in pancreatic cancer also took the spotlight. This innovative approach targets the KRAS G12D mutation, a common driver of pancreatic cancer. While specific details from this trial remain limited pending further release, the presentation suggests a promising new avenue for tackling this challenging cancer.

Other Notable Research at AACR 2025

Beyond the aforementioned clinical trials, MD Anderson researchers presented numerous other impactful studies. Here are a few highlights:

• Werner Helicase Inhibitor: A first-in-human Phase I trial investigated RO7589831, a first-in-class covalent Werner Helicase (WRN) inhibitor. WRN plays a crucial role in DNA repair, making it a potential target in microsatellite instable (MSI) cancers. Early results demonstrated promising activity across various tumor types, even in heavily pretreated patients.
• Tyrosine Kinase Inhibitor: Updated results from the Beamion LUNG-1 trial showcased zongertinib, a novel tyrosine kinase inhibitor (TKI). This potent and selective TKI targets specific receptors within tumor cells and has shown efficacy in patients with HER2-mutant non-small cell lung cancer.
• Combination Therapy for DNA Repair-Deficient Cancers: A trial combining olaparib, a PARP inhibitor, and pembrolizumab, an anti-PD-1 immunotherapy, yielded encouraging results in cancers with homologous recombination deficiencies. This combination targets DNA repair pathways, offering a potential therapeutic strategy across multiple tumor types.
• Treatment for EGFR Therapy Side Effects: Researchers tested LUT014 gel, a topical BRAF2 inhibitor, to treat acneiform rash, a common side effect of anti-EGFR therapies in colon cancer patients. The gel proved safe and effective, potentially improving quality of life for patients undergoing this treatment.

MD Anderson’s Continued Leadership

MD Anderson’s strong presence at AACR 2025, including five plenary talks and numerous oral presentations, underscores its dedication to advancing cancer research and patient care. The institution’s commitment to translational research—bridging laboratory discoveries with clinical practice—is evident in the diverse range of studies presented. The presented research, as of April 28, 2025, offers a glimpse into the future of cancer care, with personalized therapies, targeted treatments, and innovative approaches poised to transform patient outcomes. As further details emerge from these studies, the potential for improved cancer prevention, diagnosis, and treatment becomes increasingly clear.
