Innovative Treatments Tackle Aggressive Cancers at AACR

3 June 2024
The American Association for Cancer Research's annual gathering has shed light on several crucial trends in cancer therapy development. The primary focus has been on challenging malignancies with poor prognosis and significant unmet medical needs. For instance, pancreatic cancer, which has a grim five-year survival rate of only 12%, was a key area of discussion.

Among the highlighted treatments were Bristol Myers Squibb's Opdivo, an immunotherapy drug, and a messenger RNA vaccine being developed by BioNTech and Genentech. The former showed positive results in a trial for neoadjuvant pancreatic cancer, suggesting an improvement in patient outcomes. The latter vaccine is showing promise in treating a particularly aggressive form of cancer.

The resurgence of cancer vaccines was a prominent theme, with advancements in treating various cancers, including advanced liver, head and neck, non-small cell lung, and glioblastoma. The latter, a highly aggressive brain cancer, typically offers a five-year survival rate of just 10%. A Phase I study of a dendritic cell vaccine by Diakonos Oncology demonstrated a significant increase in survival rates among patients.

Other innovative approaches are showing promise, with antibody-drug conjugates (ADCs) being a significant area of focus. Companies like Vincerx Pharma and Merck, in collaboration with Kelun-Biotech, are reporting potential benefits in treating metastatic and gastric cancers, respectively.

The meeting also showcased other modalities, such as Synthekine's STK-012, an IL-2 partial agonist, which has shown favorable efficacy without the associated toxicities of IL-2 therapies. TILT Biotherapeutics reported positive signs when combining their oncolytic adenovirus with Merck's Keytruda in a trial for ovarian cancer.

AstraZeneca's next-generation PARP1 inhibitor is another therapy that has captured attention, with the potential to reduce the toxicities associated with PARP inhibitors. Experts are optimistic about combining this selective inhibitor with other treatments for enhanced benefits.

The progress in cancer treatment is not just about the data; it's also about the human impact. Small improvements can translate to precious additional time for patients, allowing them to celebrate more life milestones.

While solid cancers present unique challenges, advancements are being made. The five-year survival rate for pancreatic cancer has seen a slight increase, and the overall cancer death rate in the U.S. has significantly declined since 1991. The anticipation for further breakthroughs at future oncology meetings remains high, with the hope that these developments will continue to improve patient outcomes and survival rates.
