Together with cash on hand, the fully leveraged facility extends Aptevo's funding runway into 2029, enabling achievement of key clinical and preclinical milestones
SEATTLE, WA / ACCESS Newswire / January 9, 2026 / Aptevo Therapeutics Inc. (NASDAQ:APVO), a clinical-stage biotechnology Company focused on developing novel immune-oncology therapeutics based on its proprietary ADAPTIR® and ADAPTIR-FLEX® platform technologies, today announced that the Company has entered into a $60 million equity line of credit (ELOC) agreement with Yorkville Advisors Global, LP, strengthening the Company's financial flexibility as it continues to advance its clinical and preclinical pipeline of multispecific anti-cancer agents that are differentiated by design.
The facility provides Aptevo with access to capital, allowing the Company to raise funds incrementally, at its discretion, and under market-based conditions. Further, an ELOC offers affordable capital financing with minimal fees and no warrants. Proceeds from the ELOC will be used to support ongoing clinical development, advance preclinical programs, and fund general corporate purposes.
"This agreement offers added flexibility and control over how and when we access capital," said Daphne Taylor, Chief Financial Officer at Aptevo. "Importantly, the fully leveraged facility plus cash on hand is sufficient to fund us for three years, into 2029. During this time, we plan to continue generating clinical data and advancing differentiated assets across the portfolio focusing on execution and value creation."
The ELOC complements Aptevo's existing capital resources and is designed to support the Company's disciplined approach to balance sheet management, while preserving optionality around future strategic and growth decisions.
Under the terms of the agreement, Aptevo has the right, but not the obligation, to sell shares to the counterparty from time to time, subject to customary conditions and limitations. The Company is not required to draw on the facility and retains full discretion over its use.
Aptevo's portfolio includes five CD3-engaging assets anchored by mipletamig, a first-in-class CD123 x CD3 bispecific currently being evaluated in RAINIER, a Phase 1b/2 trial for frontline AML. In total, mipletamig has been evaluated in more than 100 patients across three trials, where mipletamig has consistently demonstrated high remission rates and a favorable safety and tolerability profile, with no observed events of cytokine release syndrome in frontline patients treated to date.
Building on this clinical validation, Aptevo has built a portfolio of tumor-directed CD3 programs, including bispecific candidates APVO442 (PSMA × CD3) for prostate cancer and APVO455 (Nectin-4 × CD3) for solid tumors, as well as trispecific candidates APVO451 and APVO452. All incorporate the Company's proprietary application and unique use of the CRIS-7-derived CD3 binding domain, designed to enable tumor-focused immune activation with the potential for meaningful antitumor activity while also prioritizing safety and tolerability.
About Aptevo Therapeutics

Mipletamig has received orphan drug designation ("orphan status") for AML according to the Orphan Drug Act. ALG.APV-527, a bispecific conditional 4-1BB agonist, designed to only be active upon simultaneous binding to 4-1BB and 5T4, is being co-developed with Alligator Bioscience and was most recently evaluated in a Phase 1 clinical trial for the treatment of multiple solid tumor types likely to express 5T4. The Company has six preclinical candidates with different mechanisms of action designed to target a range of solid tumors. All pipeline candidates were created from two proprietary platforms, ADAPTIRand ADAPTIR-FLEX. The Aptevo mission is to improve treatment outcomes and transform the lives of cancer patients.
