Comanche is a biopharmaceutical company developing novel siRNA molecules for the treatment of preeclampsia. Our purpose is to lower the risks of pregnancy and prematurity worldwide by safely sustaining natural pregnancy and allowing for fetal maturation. We envision a world where all pregnant women have access to safe and effective therapies that are evidence-based, cost-effective and sustainable. Our mission is to prevent or treat preeclampsia at its root cause.

Leuko is developing the first non-invasive white blood cell device. White blood cell assessment is a first-line indicator for various medically-relevant situations, ranging from chemotherapy management to the detection of life threatening infections worldwide. This test is currently invasive and not readily accessible - it requires patient travel, blood draws and laboratory infrastructure. Based on MIT research, Leuko is re-imagining the way to perform these tests without extracting blood and in a portable device.

OliX Pharmaceuticals is a clinical stage pharmaceutical company developing therapeutics based on the science of RNAi to address a wide variety of illnesses. The Company has developed core platforms (asymmetric siRNA, cell-penetrating asiRNA) targeting locally administrable diseases, such as hypertrophic scars, hair loss, and age-related macular degeneration (AMD). OliX's third RNAi therapeutic platform, GalNAc-asiRNA, targets multiple liver diseases, including NASH/diabetes and HBV. For the general welfare of human beings, OliX is constantly endeavoring to become a leader in the global biotechnology industry by innovating and expanding its pipeline, even to the undruggable diseases.

OncoTherapy Science, Inc. provides pharmaceutical companies with yielded drug candidates by using outcomes obtained from joint research with universities and companies. These outcomes include oncogene information isolated by comprehensive analysis of genes specifically expressed in cancer cells and functional analysis information of proteins produced by oncogenes and other gene products. We have also been performing research and development business regarding medications.

Phio Pharmaceuticals Corp. (Nasdaq: PHIO) is a clinical stage biotechnology company whose proprietary INTASYL™ RNAi technology makes immune cells more effective in killing tumor cells. INTASYL is the only self-delivering RNAi technology focused on immuno-oncology therapeutics. INTASYL drugs precisely target specific proteins that reduce the body’s ability to fight cancer, without the need for specialized formulations or drug delivery systems. Phio was co-founded by Nobel Laureate Craig Mello, who was awarded the Nobel prize in 2006 for his discovery of RNAi, which has broad therapeutic applications. Our founders opened up a whole new field of biology when they discovered RNAi, and we continue their pioneering efforts today through our work with INTASYL. We’re committed to discovering and developing innovative cancer treatments for patients, creating new pathways for a cancer-free future.
