About CTMA:

Founded in 2014 in partnership with leading international clinical trials experts and global “Key Opinion Leaders”, CTMA is a Med Tech start-up that has a high added-value web application used by physicians to boost patient recruitment in clinical trials by facilitating the identification of potentially eligible patients and thus facilitate the development of new drugs.
