Companies recently identified clinical study sites engaging in fraudulent practices, reducing success in Alzheimer's disease (AD) clinical trials. Successful trials are reliable…
When the sample size a conventional design demands is larger than the trial you can run, a Global Statistical Test lets the clinical-endpoint hypotheses be tested anyway. The paper sets out when GST applies, how it is pre-specified, and how it has been received in review.

Abstract: In general, the invention relates to a pharmaceutical dose having R-flurbiprofen as the active ingredient that upon oral administration of a single dose to a fasting subject provides a Cmax of about 30-95 µg per mL. When the dose is administered to an individual having mild-to-moderate Alzheimer's disease (or desiring protection against Alzheimer's disease) twice daily for at least 4 months according to the described guidelines, an improvement or lessening in decline of cognitive function as characterized by cognition tests is observed in the patient. The composition of the invention is formulated with one or more pharmaceutically acceptable excipients, salts or carriers.

Abstract: To evaluate the safety and tolerability and pharmacokinetic properties of R-flurbiprofen (Tarenflurbil) in normal elderly individuals and to determine the effect of the drug on amyloid beta 42 (Abeta42) levels, we conducted a double-blind, placebo-controlled study of 48 healthy subjects aged 55 to 80. Three successive cohorts were randomized to doses of 400, 800, or 1600 mg/d, or placebo, given as 2 divided doses for 21 days. Blood and cerebrospinal fluid were collected for pharmacokinetic studies and measurement of Abeta levels at baseline and on day 21. R-flurbiprofen was well-tolerated at all 3 doses. The compound penetrated the blood-brain barrier in a dose-dependent manner. From baseline to 21 days, comparisons between study groups revealed no significant differences in changes of cerebrospinal fluid Abeta42 levels and no significant differences in changes of plasma Abeta42 levels at the time of trough drug level at 21 days of treatment. Further analysis of drug concentration-response for plasma samples showed that at the time of peak plasma concentration, higher plasma drug concentration was related to lower Abeta42 plasma levels (P=0.016). R-flurbiprofen had an excellent safety profile and showed dose-dependent central nervous system penetration. Exploratory analyses of plasma Abeta and peak drug levels suggested a short-term effect in plasma that warrants independent verification. The safety, tolerability, and pharmacokinetic profile of R-flurbiprofen in these older individuals support the ongoing studies of this compound in patients with Alzheimer disease.

Background: Tarenflurbil is a Selective Ab42-Lowering Agent (SALA) that lowers brain levels of Ab42 in a mouse model of AD and chronic dosing in this model prevents defects in learning and memory. These data and the Phase-2 study indicating sustained benefit in activities of daily living, global function and cognition in mild AD patients, suggest the potential for tarenflurbil to have disease-modifying properties. Methods: This was a placebo-controlled, 1-year study evaluating tarenflurbil in 207 patients with mild-to-moderate AD. At randomization, 94% of subjects were on stable acetylcholinesterase inhibitor therapy. An exploratory post-hoc analysis was performed which compared time to adverse psychiatric events between treatment groups. Results: In subjects with mild AD (MMSE 20–26) was a significant delay in time to clinically significant adverse psychiatric events, 800 mg BID compared to placebo (p=0.011). Among 35% of the placebo group who had an event, the median time was approximately 106 days. In the 800 mg BID group, the median time to event was greater than 333 days with only 14% of this group having an event. The most common psychiatric events reported in the placebo group were agitation, aggression, confusional state and depression.

Abstract: The violent and peaceful behaviors of 115 children who had or had not witnessed domestic violence were measured in five types of simulated conflict. Witnesses did not differ from nonwitnesses in conflicts involving limited resources, jealousy over possessions, or intimidation; witnesses were significantly more violent in conflicts involving aggression and exclusion. The most violent responses were found among abusers' sons who had been excluded by peers.
