What Tesofensine Is

Tesofensine is a small molecule chemical compound with the molecular formula C17H23Cl2NO and a molecular weight of about 328.3. It has no approved drug label, meaning no FDA-sanctioned indication, dosing information, or official mechanism-of-action statement exists for it. Any use of tesofensine outside registered research settings falls outside approved medical practice.

Trial Footprint

Thirteen clinical trials referencing tesofensine are registered. Among the sampled studies, one Phase 2 trial evaluated the safety and tolerability of co-administering tesofensine with metoprolol in subjects with hypothalamic injury-induced obesity over 48 weeks, and it has completed. A separate completed Phase 2 trial examined three doses of tesofensine (referred to as NS 2330) in patients with mild to moderate Alzheimer's type dementia. A completed Phase 1 study also investigated the compound's pharmacokinetic profile.
