3,5-Diiodothyropropionic acid (DITPA), a carboxylic acid analog with low metabolic activity, was observed to induce alpha-MHC mRNA in heart cell culture with EC50 approximately 5 x 10(-7) M. Zarion Pharmaceuticals was developing DITPA (3,5-diiodothyropropionic acid), a thyroid hormone analogue, for the treatment of Allan-Herndon-Dudley syndrome. In May 2013, the US FDA granted DITPA orphan drug status for the treatment of Allan-Herndon-Dudley syndrome. However, development of DITPA for the treatment of Allan-Herndon-Dudley syndrome was discontinued.

Sample Use Guides

Study of 3,5-Diiodothyropropionic Acid (DITPA) in Hypercholesterolemic Patients: Sixty (60) patients will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (i.e., 20 patients per treatment group): DITPA at 90 mg/day (45 mg twice a day [BID] taken orally) DITPA at 180 mg/day (90 mg BID taken orally) Those patients randomized to receive DITPA at 90 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for 10 weeks. Those patients randomized to receive DITPA at 180 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for the next 2 weeks, and then 180 mg/day for 8 weeks.
