OTL-0038 or OTL-38, a fluorescent-labelled folate receptor-α (FRα) targeted imaging agent that accumulates in vivo in tumor cells expressing FR. OTL38 is currently in ongoing Phase 3 clinical trial in ovarian cancer and successfully completed phase 2 clinical trial in lung cancer. OTL38 is being evaluated for its ability to help surgeons locate and remove hard-to-find cancerous lesions that are often widespread. In 2014, the OTL-38 molecule was granted orphan drug status which can be given to the maker of a drug that treats rare conditions or diseases and offers protection from competition for a period of time. In addition, OTL-38 was studied in phase II clinical trials in the Netherlands for the diagnosis of endometriosis.
