	Certara and DMTC Ltd have entered into a research collaboration to evaluate the preventative use of chloroquine in health care workers at risk of infection from the novel coronavirus strain that causes COVID-19. Certara will support the DMTC-led clinical trial by analyzing study data to develop mathematical models to understand the viral time course and factors impacting drug exposure and prophylactic response in health care workers. The study is a randomized, controlled study of healthy, adult healthcare workers drawn from military and civilian workforces, at risk of SARS-CoV-2 infection. Participation in the trial is entirely voluntary, subject to fully informed consent and strict admittance criteria.
