Expect These Alzheimer Phase 3 Trial Results in 2016

Expect These Alzheimer Phase 3 Trial Results in 2016

While you’re waiting for other stuff to happen to Martin Shkreli, anticipate these results from interventional phase 3 trials in Alzheimer disease in 2016.*

February 2016

  • Safety and Efficacy Study Evaluating TRx0237 in Subjects With Mild to Moderate Alzheimer’s Disease: Tau Therapeutics will complete its international, 15-month, phase 3 study of 2 doses of the anti-tau TRx0237 in 800+ people with mild-moderate AD. Primary efficacy measures are the ADAS-cog11 and the ADCS-CGIC. Secondary efficacy measures include the ADCS-ADL23 and the MMSE. Biomarkers to support any disease-modifying effects are temporal-lobe glucose uptake via FDG-PET and whole-brain volume via MRI. In this phase 3 study and another (see below), TRx0237 (75 or 125 mg bid) will be delivered in a new “stable reduced form” (LMTX®), to address any delivery issues in the phase 2 trial.
  • The Study of Nasal Insulin in the Fight Against Forgetfulness (SNIFF**): Sponsored by the University of Southern California with collaborators Wake Forest and the National Institute on Aging, this placebo-controlled, 18-month, phase 2/3 study is assessing the potential cognitive benefits of intranasal insulin (Humulin® R U-100) in 240 people with amnestic MCI or mild AD. Primary outcome measures include the ADAS-cog12 and daily-functional outcomes. Maybe there is a market for Afrezza® after all?

May 2016

October 2016

  • Study of Lu AE58054 in Patients With Mild-Moderate Alzheimer’s Disease Treated With Donepezil (STARSHINE): Lundbeck and Otsuka will complete an international, 24-week, phase 3 trial of their 5-HT6-receptor antagonist (Lu AE58054, idalopirdine) in 930 people with mild-moderate AD. All enrollees are taking 10 mg of donepezil. The primary outcome measure is the ADAS-cog. Lu AE58054 is generally considered a symptomatic therapy (like donepezil), but anticipate Lundbeck/Otsuka to make claims (outright or veiled) about disease modification–providing that cognition data are positive.

December 2016

AD = Alzheimer disease; ADAS-cog = Alzheimer’s Disease Assessment Scale-cognition; ADCS-ADL23= Alzheimer’s Disease Cooperative Study – Activities of Daily Living; ADCS-CGIC = Alzheimer’s Disease Cooperative Study – Clinical Global Impression of Change; CSF = cerebrospinal fluid; FDG-PET = 18F-fluorodeoxyglucose positron emission tomography; MCI = mild cognitive impairment; MMSE = Mini-Mental State Examination; MRI = magnetic resonance imaging.
* Based on my guided search of clinicaltrials.gov. So warning: the list may not be complete.
** Ugh.
