- Announcement August 19, 2026; detailed data not yet released
- First positive Phase 3 result for individualized neoantigen therapy
- First positive Phase 3 for mRNA-based cancer therapy
- INTerpath-001 trial in stage IIB-IV melanoma patients
- Met primary endpoint: recurrence-free survival
- Met key secondary endpoint: distant metastasis-free survival

7.5 Daraxonrasib reshapes pancreatic cancer survival rates in clinical trials¶
Daraxonrasib, a new pancreatic cancer drug targeting KRAS mutations, nearly doubled survival rates in clinical trials, extending median survival to approximately 15 months for previously treated patients with advanced disease. The FDA approved it for expanded access in May 2026 and fast-tracked it for full approval later that year, offering hope for one of the deadliest cancers.
- Survival extended to ~15 months vs. <12 months historically
- KRAS-mutation targeting mechanism
- FDA expanded access approved May 1, 2026
- Presented at ASCO 2026 on May 31
- Pancreatic cancer kills ~53,000 Americans annually

7.5 Brain Organoids Matured Like Human Brains Over Five-Year Study¶
Harvard researchers maintained brain organoids alive for over five years, during which they matured and displayed molecular and genetic signatures consistent with human brains. The extended development suggests organoids could model early stages of neurological diseases.
- Brain organoids sustained for 5+ years; eraser-sized balls of tissue
- Continued to progress through developmental stages matching human brain signatures
- Led by developmental neurobiologist Paola Arlotta; junior scientist Irene Faravelli conducted analysis
- Potential applications in understanding early neurological disease stages

7 Silver nanoparticles boost DNA assembly efficiency fivefold in Japanese breakthrough¶
Japanese researchers at Nagoya and Gifu universities developed a method using PEG-coated silver nanoparticles to cut and assemble DNA with two to five times greater efficiency than conventional restriction enzymes. The technique, published in Nucleic Acids Research, could accelerate construction of large DNA sequences for gene therapies, cancer vaccines, and engineered crops.
- Silver nanoparticles coated with polyethylene glycol (PEG) slice DNA and create longer sticky ends
- DNA cleavage efficiency reached ~50% at 70°C and nearly 100% at 95°C within two hours
- Two to five times higher efficiency than conventional restriction enzyme methods
- Applications include gene therapies, cancer vaccines, and engineered drugs

7 Breast cancer surge among Asian American women outpaces screening explanations¶
A UC San Francisco study found invasive breast cancer incidence among Asian American women rose over 3% annually from 2000–2022, with particularly sharp increases in younger women and aggressive cancers. The surge far outpaces screening improvements, suggesting undiscovered risk factors beyond reproductive and lifestyle changes.
- Invasive breast cancer incidence rose >3% annually across nearly every Asian American ethnic group 2000–2022
- Among Chinese American women, triple-negative breast cancer increased >6% annually 2017–2022
- By 2022, incidence among Asian American women under 50 comparable to non-Hispanic white women same age
- Analyzed ~150,000 cases from SEER across 9 AANHPI populations in 14 states

7 Engineered probiotic bacteria used as drug factories to treat pancreatic cancer in animal studies¶
University of Chicago researchers developed BifidoSumIL-2, an engineered probiotic bacterium strain that infiltrates pancreatic tumors and delivers modified interleukin-2 to boost antitumor immune response. In animal models, the therapy slowed tumor growth and proved more effective when combined with chemotherapy, radiotherapy, or immunotherapy, addressing pancreatic cancer's resistant "cold" tumor microenvironment.
- Engineered strain: Bifidobacterium longum carrying SumIL-2
- SumIL-2 is modified interleukin-2 activating cancer-fighting T cells
- Bacteria thrive in low-oxygen tumor environments while avoiding healthy tissues
- Slowed pancreatic tumor growth in animal models
- Most effective when combined with chemotherapy, radiotherapy, or immunotherapy
- Published in Science Advances; interdisciplinary collaboration at University of Chicago
