| Immunitas is unlocking human immunology using novel single cell analyses to develop targeted therapeutics for patients with challenging, complex cancers. Translating findings from laboratory research to meaningful clinical advances in humans is a longstanding challenge in the oncology field. Immunitas was founded to directly address this problemand unlock a variety of novel drug targets based on discovery rooted in human biology. They are pursuing this goal with a team of pioneers in these areas across their scientific founders, management, and investors.At Immunitas, they employ a single cell sequencing platform to dissect the biology of immune cells in human tumors. Their focus on human samples allows us to start with and stay closer to the most relevant and translatable biology for patients and accelerates the pace of their research. They are identifying novel, exciting oncology targets and, importantly, developing key biomarkers to guide the selection of patients who may benefit from their new drugs. They are leveraging expertise in antibody discovery and engineering to create powerful therapies that modulate these targets, and are currently advancing a number of programs toward early human studies. | $58M / Series B / Aug 18, 2021 | ||

The productcandidates are DCR-PHXC (for primary hyperoxaluria), DCR-undisclosed (for orphan genetic disease), DCR-PCSK9 (for cardiovascular disease), and DCR-HBV (for hepatitis B virus) among others.The company was founded in 2007 and is headquartered in Lexington, Massachusetts. | $70M / Post-IPO Debt / Mar 30, 2017 | ||
| Bionano Genomics is a biotechnology company that specializes in genome mapping and analysis. The company develops and markets the Saphyr system, which is a platform for ultra-sensitive and ultra-specific structural variation detection in DNA. Structural variations are alterations in the DNA structure, such as insertions, deletions, inversions, andtranslocations, that can be associated with various genetic disorders and diseases, including cancer.Bionano Genomics' Saphyr system uses a technology called optical genome mapping (OGM) to analyze long DNA molecules. OGM allows for the direct visualization and analysis of structural variations in the genome without the need for sequencing. This technology can provide valuable insights into the structural variations in an individual's genome, which can be important for understanding disease mechanisms, and genetic disorders, and for guiding personalized treatment strategies. | $31.7M / Series D / Aug 01, 2016 | ||
