- Aptevo Therapeutics Inc. Aptevo Therapeutics Inc. (Nasdaq: APVO), a clinical-stage biotechnology company headquartered in Seattle, Washington and founded in 2016 as a spin-off from Emergent BioSolutions Inc., focuses on developing novel bispecific and trispecific immunotherapies for cancer treatment using its proprietary ADAPTIR and ADAPTIR-FLEX platform technologies. The company advances a pipeline including two clinical-stage candidates—mipletamig (CD123 x CD3 bispecific T-cell engager in Phase 1b/2 for frontline acute myeloid leukemia, demonstrating 89% remission rates in evaluable frontline patients across two trials with no cytokine release syndrome observed) and ALG.APV-527 (5T4 x 4-1BB bispecific conditional agonist co-developed with Alligator Bioscience in Phase 1 for solid tumors including non-small cell lung cancer, head and neck, colorectal, pancreatic and breast cancers)—along with six preclinical candidates such as APVO603, APVO442 and APVO711 targeting solid tumors including prostate cancer. These multispecific antibody candidates enhance immune system activation against hematologic malignancies and solid tumors primarily in the United States. In recent developments, Aptevo introduced its first trispecific T-cell engagers APVO451 (for multiple solid tumors) and APVO452 (for prostate cancer) in 2025, expanding its CD3-directed portfolio to five molecules leveraging the CRIS-7-derived CD3 binding domain for improved safety; the company raised approximately $22.8 million in equity financing since Q2 2025 through at-the-market offerings and a Standby Equity Purchase Agreement, extending its cash runway into Q4 2026.
