Company context
We are a clinical-stage biotechnology company developing, through our subsidiaries, RNA interference (RNAi) therapies for cancers driven by mutations in the Kirsten rat sarcoma viral oncogene homolog (“KRAS”). Our approach targets a significant unmet medical need, as treatment innovation for KRAS-driven cancers has historically lagged despite KRAS being one of the most common oncogenic drivers across solid tumors. In pancreatic cancer, for example, approximately 92% of patients have this mutated oncogene. While multiple pharmaceutical companies are pursuing strategies to inhibit KRAS and thereby limit its downstream signaling, our approach is differentiated by targeting the root cause of oncogenic signaling; our lead product candidate, SIL204, is a second-generation siRNA therapy that is engineered to suppress the KRAS oncogene itself, preventing the production of the oncogenic protein. We utilize an integrated treatment approach that combines administering SIL204 both directly into the tumor and systemically via subcutaneous injection, in combination with standard-of-care chemotherapy. In a previous Phase 2 clinical trial with our first-generation siRNA, the combination of siRNA and standard-of-care chemotherapy demonstrated an overall survival benefit compared to standard-of-care chemotherapy alone. Building on preclinical advancements and regimen optimization, we believe SIL204 has the potential to further improve clinical outcomes.
