A new drug significantly extended survival for lung cancer patients resistant to standard treatment.
A Phase 3 trial, OptiTROP-Lung04, found that sacituzumab tirumotecan (sac-TMT), a TROP2-targeted antibody-drug conjugate, significantly improved progression-free survival and overall survival in patients with EGFR-mutated non-small cell lung cancer who had progressed after EGFR-TKI therapy.
Among 376 patients, sac-TMT extended median PFS to 8.3 months versus 4.3 months for chemotherapy, reducing disease progression or death by 51%.
Interim overall survival data showed a median not reached with sac-TMT versus 17.4 months with chemotherapy, a 40% lower risk of death.
Benefits were consistent across subgroups, with higher response rates and a manageable safety profile.
The drug is already approved in China for several cancer types and is under review for additional indications.
