PHP Biotech is a US-based biotechnology company developing first-in-class nanobody therapeutics for the most aggressive and hard-to-treat cancers. Our lead candidate, PHP53-nb, is a patented, humanized camelid nanobody that enters cancer cells and reactivates mutant p53 to trigger apoptosis—showing strong anti-tumor efficacy and low toxicity in model systems across triple-negative breast cancer (TNBC), ovarian, and other tumors. Backed by a world-class scientific team and global CRO and CDMO partners, we're advancing a versatile platform and pipeline to transform cancer care and improve patient outcomes worldwide.
