Greenwich Gets Fast Track for Breast Cancer Therapy
FDA has granted Greenwich LifeSciences fast track status for GLSI-100, an investigational immunotherapy aimed at preventing breast cancer recurrences. The designation applies to HLA-A*02-genotype patients with HER2-positive breast cancer who have completed standard HER2-targeted therapy.
The company says GLSI-100 has already shown promise in earlier studies. In a Phase 2b trial involving HER2-positive breast cancer patients, the treatment reduced metastatic recurrences by 80% or more over five years compared with placebo. The therapy was well tolerated, with no serious adverse events reported, it says.
The ongoing Phase 3 FLAMINGO-01 study, led by Baylor College of Medicine, is enrolling up to 750 patients globally to further evaluate GLSI-100’s safety and efficacy, according to the company.
