Aptevo Therapeutics Collects $3.3 Million In Escrow Funds From Saol Therapeutics

SEATTLE, Jan. 03, 2019 (GLOBE NEWSWIRE) — Aptevo Therapeutics Inc. (Nasdaq: APVO), a biotechnology company focused on developing novel oncology and hematology therapeutics, announced today that it has collected $3.3 million in escrow funds from Saol Therapeutics related to a purchase agreement between the companies under which Saol Therapeutics acquired three hyperimmune products previously marketed by Aptevo, WinRho SDF, HepaGam B, and VARIZIG.

The transaction, completed in September 2017 and valued at up to $74.5 million, included an upfront payment to Aptevo of $65 million, of which approximately $3.3 million was held in an escrow account.  The escrow funds have now been collected in full by Aptevo, with no claims being made against it by Saol.  In addition, Aptevo is also eligible to receive a potential milestone payment of up to $7.5 million from Saol related to the achievement of a gross profit milestone threshold.  In addition, Aptevo may receive up to $2 million related to collection of certain accounts receivable from Saol.

“We’re pleased to have collected the full amount of escrow funds from Saol, which together with our existing cash and cash flow from our marketed product, IXINITY, further strengthens our cash position as we make important progress in 2019 advancing two lead ADAPTIR bispecific antibody programs, APVO436 and APVO210, being evaluated for the treatment of acute myeloid leukemia and autoimmune disorders, respectively.  Dosing in the APVO436 Phase 1 clinical study commenced recently and we anticipate beginning a Phase 1 clinical study of APVO210 in healthy volunteers this quarter,” said Jeff Lamothe, Chief Financial Officer.
