Phase II Trial Shows Single-Fraction SBRT Effective for Early-Stage Lung Cancer

Apr 03, 2026

A phase II clinical trial shows single-fraction stereotactic body radiation therapy with 30 Gy is as effective as three-fraction SBRT with 60 Gy for early-stage NSCLC. The study of 98 patients found no meaningful differences in survival, recurrence, or side effects between the two approaches. This could reduce costs and increase convenience for patients unable to undergo surgery.

Trodelvy-Keytruda Combo Shows Promise in First-Line Metastatic TNBC

Apr 03, 2026

The ASCENT-04 trial shows Trodelvy plus Keytruda extends progression-free survival by 3.4 months in PD-L1-positive metastatic triple-negative breast cancer. Meanwhile, the ToPCourT trial investigates trilaciclib combined with pembrolizumab and chemotherapy for advanced TNBC. These developments signal evolving treatment approaches for this aggressive breast cancer subtype.

Revolution Medicines Begins Phase 3 Trial for Daraxonrasib in First-Line Pancreatic Cancer

Apr 03, 2026

Revolution Medicines has initiated patient treatment in the Phase 3 RASolute 303 trial testing daraxonrasib as first-line therapy for metastatic pancreatic cancer. The company also expects top-line data from its Phase 3 RASolute 302 trial in second-line pancreatic cancer in the first half of 2026. Both trials are evaluating the oral RAS(ON) inhibitor in pancreatic ductal adenocarcinoma, a highly lethal cancer with significant unmet medical need.

Novel ADC Shows Significant Survival Benefit in Pretreated EGFR-Mutated NSCLC

Apr 02, 2026

The antibody-drug conjugate sacituzumab tirumotecan demonstrated significant survival benefits in pretreated EGFR-mutated NSCLC, with median overall survival of 20.0 months versus 13.5 months for docetaxel. The treatment also showed superior progression-free survival and objective response rates with a favorable safety profile compared to chemotherapy.

Oncolytics Biotech Receives FDA Fast Track Designation for Pelareorep in Colorectal Cancer

Apr 01, 2026

Oncolytics Biotech received FDA Fast Track Designation for pelareorep in KRAS-mutant colorectal cancer based on data showing 33% response rate and 27-month median survival. The company is launching a Phase 2 study and recently completed reincorporation from Canada to Nevada. This marks the second Fast Track Designation for pelareorep in gastrointestinal cancers.

Phase 3 Breast Cancer Trial Data Highlights from Q1 2026

Apr 01, 2026

Multiple phase 3 breast cancer trials reported significant findings in early 2026, including positive results for novel therapies across different subtypes. Key data includes progression-free survival benefits for palbociclib in HR-positive, HER2-positive advanced breast cancer and investigations of antibody-drug conjugates and combination therapies. Full trial findings are expected to be presented at upcoming medical meetings.

Tempest Therapeutics Reports 2025 Financial Results and Clinical Progress

Mar 30, 2026

Tempest Therapeutics reported 2025 financial results showing $7.7 million in cash and highlighted clinical progress including 100% complete response rate in TPST-2003 CAR-T trial and multiple FDA designations for amezalpat in hepatocellular carcinoma. The company completed strategic CAR-T asset acquisition and plans Phase 2b registrational study for its lead program in 2026.

Tumor Burden Linked to Worse Survival in Rare Cancers Treated with Immunotherapy

Mar 30, 2026

A secondary analysis of the Southwest Oncology Group S1609 trial found that larger baseline tumor burden correlated with shorter overall survival but not progression-free survival in rare cancer patients treated with nivolumab plus ipilimumab. The study of 722 patients showed tumor burden was independently associated with survival outcomes but not predictive of tumor regression after dual immunotherapy.

Osimertinib-Chemotherapy Combo Shows Major Benefit in High-Risk EGFR/TP53 NSCLC

Mar 28, 2026

The phase III TOP study shows osimertinib plus chemotherapy more than doubles progression-free survival to 34 months versus 15.6 months with osimertinib alone in EGFR/TP53 mutant NSCLC. The combination achieved an 82.9% response rate and represents a new strategy for this high-risk subgroup. Research continues into resistance mechanisms, including cancer-associated fibroblasts' role in promoting osimertinib resistance.

Sac-TMT Shows Significant Survival Benefit in Pretreated EGFR-Mutated NSCLC

Mar 28, 2026

Sacituzumab tirumotecan demonstrated a median overall survival of 20.0 months versus 13.5 months with docetaxel in pretreated EGFR-mutated NSCLC patients. The phase 2 OptiTROP-Lung03 study showed a hazard ratio of 0.63 for overall survival benefit with the TROP2-directed antibody-drug conjugate.

Early Immunochemotherapy Timing Improves Survival in Advanced Lung Cancer

Mar 28, 2026

A Phase 3 trial shows administering immunochemotherapy before 3:00 PM improves survival outcomes in advanced NSCLC. Early treatment resulted in 11.3 months progression-free survival versus 5.7 months for late treatment, and 28.0 months overall survival versus 16.8 months. The findings suggest treatment timing is a modifiable factor that can enhance efficacy without additional cost.
