Drug Profile

Osimertinib is a tyrosine kinase inhibitor marketed as Tagrisso for EGFR-mutated non-small cell lung cancer. It is used across adjuvant, locally advanced unresectable, and metastatic first-line settings, including combination regimens with platinum-pemetrexed chemotherapy. The FDA first approved it in November 2015.

Robotic Mastectomy Gains FDA Clearance as Researchers Target Drug-Resistant Cancers

FDA has cleared a robotic nipple-sparing mastectomy platform after clinical trials showed excellent results with preserved breast sensation. Researchers are advancing immunotherapy combinations for breast cancer and novel strategies to overcome drug resistance in EGFR-mutated lung cancer, including protein degraders and dual-binding inhibitors.

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

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.

FDA Approves Subcutaneous Amivantamab for EGFR-Mutated NSCLC

The FDA approved subcutaneous amivantamab for EGFR-mutated NSCLC in December 2025 based on phase 3 PALOMA-3 trial data showing noninferior efficacy with reduced infusion reactions and 5-minute administration time. The formulation decreases infusion-related reactions from 66% to 13% and improves patient convenience and quality of life. Recent MARIPOSA trial updates show amivantamab plus lazertinib extends median overall survival by at least 12 months versus osimertinib monotherapy.
