Larkspur Biosciences is a preclinical biotechnology startup focused on developing precision immunotherapies, starting with colorectal cancer (CRC) using a targeted approach based on molecular profiles. Its proprietary LarkX platform integrates genetics and immunology data to identify patient subgroups most likely to respond to tailored treatments. By leveraging insights from cancer biology and patient immune phenotypes, Larkspur aims to advance precision immunotherapies matched to specific CRC patient subgroups. The LarkX platform could enable similar targeted approaches for other cancer types pending additional research.
The company had three programs in its pipeline at preclinical stages focusing on CRC as of August 2023: 1) Program 1, developed by modifying lipids (biomolecules) to enhance immune cell activity against tumors; 2) Program 2, which focuses discovery of inhibitors against the Pin1 enzyme, which is implicated in cancer growth and spread; and 3) Program 3, announced in June 2023, which targets the TIM-1 checkpoint on B cells to potentially improve anti-tumor immunity.
Funding and Financials
In May 2023, the company launched out of stealth with USD 35.5 million in seed and Series A funding. The round was led by the Polaris Innovation Fund, 3E Bioventures Capital, and Takeda Ventures. The new funds were used for preclinical work on its lead program and for research on its secondary program.
