Obstetrician Jodie Rai has partnered with researcher Robert Kokenyesi to form Cervimark LLC, based at the Nidus Center for Scientific Enterprise incubator in Creve Coeura, MO. Cervimark aims to develop a test that will predict which women are likely to deliver at less than 37 weeks of pregnancy, the definition of a pre-term birth. If Cervimark succeeds, its test would allow doctors to intervene in the limited ways available to them--by moving rural patients closer to hospitals with neonatal intensive care units, for example--and would identify a group of patients who could be tapped as volunteers for clinical trials in the development of new and better treatments.
