About Aezea

Aezea is an antisense drug product that suppresses the expression of structurally normal or mutated p53. Cancer cells subvert the normal functioning of this protein in ways that promote their survival, including protection against the killing effects of chemotherapy or radiation. Preclinical data suggests that in normal cells, however, p53 mediates many of the chemotherapy or radiation toxicities often seen in cancer patients. Thus Aezea is expected to sensitize many cancer types, independently of their p53 mutational status, to both radiation treatment and a wide range of existing chemotherapeutic agents while simultaneously protecting normal tissues, including bone marrow, gastrointestinal epithelium and hair follicles, from standard cancer treatment toxicities.

About orphan drug designation

Orphan drug laws in both the U.S. and Europe provide economic incentives to biotechnology and pharmaceutical companies to encourage the development of drugs for rare diseases. Orphan drug status provides a seven-year period of exclusivity following FDA marketing approval in the U.S., and a ten-year period of exclusivity in Europe. Other incentives in the U.S. include tax credits related to development expenses, waiver of prescription drug filing fees (exceeding $1 million per application) and FDA assistance in clinical trial design.
