- the patients were administered either escalating doses from 400 mg to 1 ,000 mg during 20 weeks, once daily, of said thiadiazolidinedione derivative ("Active” group), o r a matching placebo ("Placebo" group). That is, patients in the Placebo group received cholinesterase inhibitor treatment and a placebo, and patients in the Active group received cholinesterase inhibitor treatment and thiadiazolidinedione derivative treatment. Particularly, 20 patients were treated with Active, and another 10 patients with Placebo. All the patients had been diagnosed of mild to moderate Alzheimer's Disease; they were aged in the range of 55 to 84 years; 20 were women and 10 were men.
- efficacy endpoints related to the assessment of cognition and global functioning were monitored at baseline and regularly throughout the study.
- Global Clinical Assessment was performed at the end of the double-blind period.
- MMSE Mini-Mental State Examination
- the MMSE is a frequently used screening instrument for AD drug studies. It evaluates orientation, memory, attention, concentration, naming, repetition, comprehension, ability to create a sentence and ability to copy two intersecting polygons. A lower score indicates greater cognitive impairment. The highest possible (best) score is 30. For further detail, see for example J. Psychiatr. Res. 1975, 12, 189, which is herewith incorporated by reference.
- ADAS-cog+ a composite questionnaire assessing memory, language, praxis functions, delayed word recall, concentration distractibility, digit cancellation and maze completion.
- the total score is calculated from the ADAS-cog+ sub scale scores and ranges from 0 (No impairment) to 95 (Errors in all sub-tests). Therefore, higher scores are associated with greater cognitive impairment.
- ADAS-cog+ a composite questionnaire assessing memory, language, praxis functions, delayed word recall, concentration distractibility, digit cancellation and maze completion.
- the total score is calculated from the ADAS-cog+ sub scale scores and ranges from 0 (No impairment) to 95 (Errors in all sub-tests). Therefore, higher scores are associated with greater cognitive impairment.
- Alzheimer Dis Assoc Disord. 2004, 18(4), 236-40 which is herewith incorporated by reference.
- the investigator evaluated the overall clinical state of the patients, in comparison with their basal state at the start of the study, in a seven point scale: markedly better, much better, slightly better, similar, slightly worse, much worse, markedly worse.
- Figure 1 the mean change in MMSE score from baseline (considered "0"), in absolute figures, for both Placebo and Active groups, are shown.
- the patients being administered Placebo showed a decline in the MMSE score during the 20 weeks, specifically by a mean value of 1.13 points in the MMSE scale, according to the expected rate of around 2.5 points per year. That means, their neurodegenerative disease continued worsening during the study.
- Placebo and Active was determined several times along the phase lla study (baseline, week 4, week 8, week 14 and week 20).
- the patients being administered Active not only did not worsen their state, maintaining the same MMSE score, but even experienced an improvement with respect to the baseline value, specifically a mean reduction of 1 .60 points in the ADAS- cog+ score.
- a clear improvement in the ADAS-cog+ score was detected in the patients receiving concurrently a cholinesterase inhibitor treatment and Active, in comparison with those being treated with a cholinesterase inhibitor and Placebo; i.e., the combined treatment of a cholinesterase inhibitor and the thiadiazolidinedione derivative has shown clearly more effective than the treatment with cholinesterase inhibitor alone, despite the Phase lla study being a relatively short study, which was initially designed for proving safety and tolerability of the Active, and not for determining efficacy of the Active.
- Cardiac disorders Particularly, the following particular adverse events were classified within the above classes: Cardiac disorders:
- the adverse events were higher in the Placebo group (being administered only cholinesterase inhibitors) than in the Active group (being administered both cholinesterase inhibitors and the thiadiazolidinedione derivative). Especially unexpected is the reduction in gastrointestinal adverse effects, which are typical and frequent side effects of the treatment with cholinesterase inhibitors. The results suggest that the adverse effects occu rri ng d u ring the treatment with cholinesterase inhibitors are reduced by co-administering the Compound, without significantly adding other adverse effects.
