At AACR (Free AACR Whitepaper) 2026, Fapon Biopharma spotlights its two core technology platforms: IL-10 biased functional engineering and antibody fusion, and VHH human-monkey cross-binding T-cell engagers. These capabilities reflect the company’s focus on developing next-generation therapeutic approaches designed to deliver differentiated efficacy, improved translational potential, and broader applicability across immuno-oncology and aotoimmune diseases.
The company’s IL-10 biased functional engineering and antibody fusion platform underpins a series of novel cytokine-based fusion proteins intended to unlock more precise immune modulation. Among the most advanced programs is FP008, a global first-in-class PD1 x IL10M fusion protein and potential next-generation backbone for cancer immunotherapy, with Phase I readout anticipated in 2026. Fapon Biopharma is also advancing FP012, a global first-in-class TL1A x IL10MM fusion protein for inflammatory bowel disease and other inflammatory indications, with IND-enabling CMC/GLP toxicology planned in 2026.
Complementing this platform is Fapon Biopharma’s proprietary VHH human-monkey cross-binding T-cell engager platform, an innovative approach designed to overcome developability and flexibility challenges associated with traditional multi-specific antibodies. This technology is represented in the company’s expanding CD3/TCR VHHs, including FPE024, a potential best-in-class CD19xBCMAxCD3 tri-specific T-cell engager for autoimmune indications, and FPE021, a potential best-in-class CDH17-targeting T-cell engager with a second signal for gastrointestinal tract cancers. Both programs are expected to enter IND-enabling CMC/GLP toxicology in 2026.
Attendees are invited to visit Booth #3856 and attend Fapon Biopharma’s abstracts to learn more about the company’s technology platforms, research strategy, and pipeline programs. Fapon Biopharma is seeking strategic partners for co-development and licensing.
