Erasca announces U.S. FDA granted FTD to ERAS-801

Erasca announced the United States Food and Drug Administration, FDA, has granted Fast Track Designation, FTD, to ERAS-801 for the treatment of adult patients with glioblastoma with epidermal growth factor receptor gene alterations. ERAS-801 is an orally bioavailable, small molecule EGFR inhibitor that exhibited substantial central nervous system penetration in animal studies. "Receiving FTD from the FDA underscores the serious unmet medical need in patients with GBM and reinforces the promise that ERAS-801 may offer as a differentiated treatment option," said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. "GBM is an aggressive malignancy with high rates of relapse and a five-year survival rate below 10%. While over half of GBM cases are driven by EGFR alterations and/or amplifications, there are no approved EGFR inhibitors for the treatment of GBM due to the lack of sufficient brain penetration to treat primary brain tumors as well as lack of activity against EGFR alterations observed in GBM, such as EGFRvIII. To help overcome these limitations, ERAS-801 was specifically designed to have high CNS penetration and broad activity against both oncogenic and wildtype EGFR. We look forward to working closely with the FDA to expedite clinical development of ERAS-801 for these patients and anticipate reporting initial monotherapy data from the Phase 1 THUNDERBBOLT-1 trial in recurrent GBM (rGBM) in the second half of 2023."
