Deal Highlights

We are building a vertically integrated radiopharmaceutical therapeutics company with our lead program in a Phase 3 clinical trial. We believe we have established a leadership position in the emerging radiopharmaceutical therapeutics modality. We have created a pipeline of multiple drug candidates, in therapeutic areas with significant market opportunities. Much like antibody drug conjugates emerged as a new and transformative treatment modality in certain cancers, we see an opportunity for innovative radiopharmaceutical therapeutics to follow a similar path. We believe the strategic investments we are making in our robust product pipeline, development capabilities, and manufacturing infrastructure position us to be an industry-leading pioneer in the broad application of radiopharmaceutical therapeutics in cancer.

We are initially focused on building a market leading somatostatin receptor type 2, or SSTR2, franchise. As multiple diagnostic and therapeutic commercial products targeting SSTR2 are available, it is a clinically validated target expressed in multiple solid tumors. Our lead drug candidate, RYZ101, is designed to deliver a highly potent alpha particle radioisotope, Actinium 225, or Ac225, to tumors overexpressing SSTR2. RYZ101 consists of DOTATATE, a peptide binder, and a chelator, bound to Ac225.

The U.S. Food and Drug Administration, or FDA, has approved the use of DOTATATE as the peptide binder for SSTR2 diagnostic imaging and therapeutic agents. We believe that a radiopharmaceutical therapeutic, or RPT, utilizing Ac225 has the potential to provide greater efficacy over approved beta particle radioisotope Lutetium 177, or Lu177, therapies. Alpha particles deliver up to 400 times higher energy compared to beta particles leading to double-stranded DNA breaks which are lethal to cancer cells.
