Lung data hold near 25% as Iovance shifts toward a biomarker-selected group

Iovance is a commercial-stage cell therapy company. Its lead product, Amtagvi (lifileucel), is approved for advanced melanoma; Iovance plans to seek approval in non-small cell lung cancer, with a filing planned for 2027.

Amtagvi's approved melanoma business has demonstrated adoption through rising sales, broader access and manufacturing improvements. Raised revenue guidance supports growth, while management expects current cash to fund operations into 2H28. Lung cancer is the larger opportunity, and the case for it has weakened. The response rate held at 24.6% across 69 patients, but 13 of the 17 responses came from a 22-patient subgroup identified after the fact. Iovance is adding a biomarker-selected registrational cohort, and the broad 2027 filing still depends on FDA discussions.
