SCYNEXIS, Inc. (NASDAQ:SCYX), a biotechnology company focused on developing innovative new therapies to address severe rare diseases, today announced that it has entered into a definitive agreement with Poxel S.A. (POXEL.PA) to acquire PXL-770 (now SCY-770).

SCY-770 is a novel, highly selective, direct AMP-activated protein kinase (AMPK) activator for the treatment of ADPKD, the leading genetic cause of end-stage renal failure. SCY-770 is designed to address many of the underlying drivers of ADPKD by reducing cyst growth and disease progression.

SCY-770 is an oral therapy that has been evaluated in eight clinical trials, with a favorable safety profile. SCYNEXIS is expected to begin a Phase 2 proof-of-concept study in ADPKD patients in Q4 2026, with an anticipated early efficacy readout in second half of 2027. SCY-770 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA).

Terms of Acquisition Agreement

Under the terms of the asset acquisition agreement, SCYNEXIS will make an upfront payment of $8 million, with future potential payments of up to $8 million in development milestones, and up to $180 million in commercial milestones, of which $125 million is triggered by annual net sales at or above $1 billion.
