First Patient Dosed In Ph 1/2 Study Of FPI-1966 In Patients With Advanced Solid Tumors Expressing FGFR3

“Dosing of the first patient in this Phase 1/2 study of FPI-1966 demonstrates our continued ability to bring innovative targeted alpha therapies (TATs) into the clinic,” said Chief Executive Officer John Valliant, Ph.D. “This study will evaluate FPI-1966 in patients with solid tumors expressing FGFR3, a validated cancer target found in multiple tumor types with substantial unmet need, notably bladder, ovarian and head and neck cancers. FPI-1966, and the growing number of TATs in our pipeline, are designed as next generation antibody drug conjugates (ADCs) in that they leverage the potency of actinium-225 and alpha particle radiation in place of chemical toxins to selectively eradicate cancer cells. Given the prevalence of the FGFR3 target, and the use of a precision medicine approach that employs an imaging analogue to enable patient selection, we believe FPI-1966 has the potential to become an important new treatment paradigm for cancer patients.”
