EpicentRx Gets Fast Track for Sarcoma Therapy
FDA has granted EpicentRx a fast-track designation for its AdAPT-001 and its combination use with checkpoint inhibitors nivolumab or atezolizumab in treating recurrent or refractory advanced or metastatic soft tissue sarcoma (STS) with disease progression after at least one prior line of therapy.
The designation was based on the therapy’s potential to “sensitize STS tumors to checkpoint inhibitors like nivolumab or atezolizumab that they previously received and failed or never previously received because of low levels of both tumor mutation burden (TMB) and T-cell inflamed gene expression profiles (GEP) that predicted for non-response,” the company says. “Supporting evidence for Fast Track designation came from Phase 1 and 2 clinical trials and an ASCO podium presentation where the activity, safety, and durability of response (progression free survival of about five months) in patients with STS and other tumor types either alone or in combination with checkpoint inhibition were on full display.”
The company describes AdAPT-001 as an oncolytic adenovirus-delivered transforming growth factor beta (TGFβ) inhibitor that is designed to “express a potent TGFβR inhibitor for local TGFβ neutralization, decreased T-Reg cell function, and superior therapeutic responses.”
