Our pipeline is comprised of several novel drug candidates including first-in-class, highly selective IV and oral SMARCA2 degraders, and a potentially best-in-class CDK9 inhibitor. We are also leveraging our expertise in targeted protein degradation to discover, develop and commercialize next generation degrader antibody conjugates (Precision ADCs) with partners.
We are advancing a diverse pipeline of first-in-class or potentially best-in-class agents for hard-to-treat solid tumors and hematologic malignancies. This includes the industry’s leading SMARCA-targeted pipeline.
Our differentiation strategy is to design and optimize each of our small molecule therapeutics to possess specific properties that have the potential to benefit patients:
- PRT3789 (SMARCA2), we sought high selectivity over SMARCA4 to elicit synthetic lethality using a targeted protein degrader approach
- For PRT2527 (CDK9), we optimized for superior selectivity over previously developed CDK9i to improve tolerability
