AstraZeneca Plc will pay Pinetree Therapeutics Inc. $25 million to license its preclinical cancer drug, PTX-299, in a deal potentially worth over $500 million that expands the global drugmaker’s oncology pipeline.
"This milestone marks an important validation of our AbReptor™ platform," Hojuhn Song, Founder and CEO of Pinetree Therapeutics, said in a statement. "We look forward to seeing them continue the development of this promising therapeutic candidate."
The agreement grants AstraZeneca an exclusive global license to develop and commercialize the first-in-class bispecific antibody degrader targeting the protein EGFR. In addition to the upfront payment, Pinetree is eligible for future development, regulatory, and commercial milestone payments, plus tiered royalties on global net sales if the drug is successfully commercialized.
The deal strengthens AstraZeneca's franchise in oncology by adding a next-generation protein degrader for EGFR-driven cancers, a common target in many tumors. For the closely-held Pinetree, the $25 million payment provides non-dilutive funding and validates its AbReptor™ antibody-based protein degradation technology.
A New Approach to Cancer Targets
PTX-299 was developed using Pinetree's proprietary AbReptor™ platform. Unlike traditional antibodies that only block a protein's function, this technology is designed to actively remove disease-associated proteins through targeted degradation. The approach aims to overcome the drug resistance that can develop with existing EGFR inhibitors.
EGFR plays a critical role in the growth and survival of cells in multiple tumor types. While EGFR-targeted therapies have transformed patient outcomes, resistance remains a significant hurdle, highlighting the need for new therapeutic strategies. By eliminating the EGFR protein itself, PTX-299 may offer a more durable response in patients with these cancers.
The licensing agreement follows a period of encouraging preclinical progress for the drug candidate. AstraZeneca will now assume all responsibility for future global development and commercialization.
The agreement provides AstraZeneca with a promising candidate that could address a major unmet need in EGFR-targeted cancer therapies. Investors will watch for AstraZeneca to announce a timeline for initiating the first clinical trials for PTX-299.
