Novel Therapeutic Nanobody
Acts selectively in p53-deficient cells. Destroys cancer.*
Our Focus
Targeting the Most Aggressive Cancers
- Breast cancer causes ~670,000 deaths annually with 2.3 million new cases worldwide (WHO).
- Triple-negative breast cancer (TNBC) is highly aggressive, with lower survival rates and few targeted treatment options.
- Our lead candidate, PHP53-nb selectively targets p53-deficient tumors using the uPAR-dependent entry to promote cell apoptosis, addressing a key driver of TNBC.
- PHP53-nb is a patented nanobody with no linkers that is internalized within cancer cells exploiting p53’s dysfunction to impair metastasis and induce apoptosis.
Mechanism of Action
PHP53-nb is a nanobody which specifically targets cancer cells. It:
Enters the cell through uPAR-driven endocytosis exploiting uPAR over-expression in p53 deficient tumors
- Triggers proteotoxic stress leading to apoptosis of cancer cells
Featured Data
PHP53-nb reduces cell viability in a dose dependent manner in both triple negative breast cancer (TNBC) (pink) and ovarian (teal) tumor cell models. Go to our science page to see how PHP53-nb reduces cell viability in other types of cancers.
