Clinical Trial Summary

This is a Phase III, multicenter, open-label extension, single-group study in male and female outpatients with mild-to-moderate Alzheimer's disease (AD) who have completed either AVA102670 or AVA102672. All subjects will receive rosiglitazone extended-release (RSG XR) 4mg once daily for the first 4 weeks of the study followed by 8mg RSG XR as adjunctive therapy to their existing dose of acetylcholinesterase inhibitor. Subject participation will last until one of 5 conditions applies. After a 52-week open-label treatment phase, subjects will attend a final Follow-Up Visit 6 weeks after the end of treatment. The primary objective of this study is to evaluate the long-term safety and tolerability of RSG XR in subjects with mild-to-moderate AD who have completed either AVA102670 or AVA102672. The secondary objective of this study is to explore further the long-term efficacy of RSG XR in terms of cognitive function and overall clinical response as a function of apolipoprotein E (APOE) e4 allele status.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With Any Adverse Events (AEs) and Severity of AEs An AE is defined as any untoward medical occurrence in a patient or clinical investigation participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. The severity of the AE'S was categorized as mild, moderate and severe. Number of participants reporting AEs during the on treatment phase of the study. Up to 76 Weeks
Secondary Number Participants With Serious Adverse Events (SAEs) and Deaths A SAE is defined as any untoward medical occurrence that, at any dose results in death, is a life-threatening condition, requires hospitalization or prolongation of existing hospitalization, results in disability or incapacity, or a congenital anomaly or birth defect. Number of participants with SAEs and deaths were reported for treatment duration of the study. Up to 76 Weeks
Secondary Number of Participants With Adverse Event of Oedema Oedema was considered as adverse event of special interest (AESI). The process for AESI selection was based on RSG's pharmacologic class and relevant AEs potentially associated with RSG. The number of participants and their percentage for the adverse event of the various types of oedema were reported. Up to 76 Weeks
Secondary Change From Baseline in Vital Sign Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) Vital signs SBP and DBP were measured at each visit. All measurements were made on the participant non-dominant arm supported at heart level, using the same cuff size and same equipment. Blood pressure was measured once, after the participant sat quietly for at least 5 minutes. DBP was measured at the disappearance of Korotkoff sounds (Phase V). If the participant was a smoker or used tobacco products, a period of 30 minutes without tobacco was allowed before taking these measurements. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication. Change from Baseline was measured as the blood pressure value recorded at specified visit minus the Baseline value. Up to 70 Weeks (including follow up)
Secondary Change From Baseline in Vital Sign Heart Rate (HR) Vital sign HR was measured at each visit. HR was measured once, after the participant sat quietly for at least 5 minutes. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication. Change from Baseline was measured as the HR at specified visit minus the Baseline value. Up to 70 Weeks (including follow up)
Secondary Change From Baseline in Vital Sign Body Weight (BW) BW was measured at all visits, without shoes and wearing light clothing. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication. Change from Baseline was measured as the body weight at specified visit minus the Baseline value. Up to 70 Weeks (including follow up)
Secondary Change From Baseline in Non-fasting Measures of Lipid Metabolism Namely Total Cholesterol (TC), High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), Triglycerides The clinical chemistry data included non-fasting measures of lipid metabolism (TC,HDL,LDL,triglycerides). Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication. Change from Baseline was measured as the lipids (TC,HDL,LDL,triglycerides) value recorded at specified visit minus the Baseline value. Up to 82 Weeks (including follow up)
Secondary Number of Participants With SBP and DBP Values of Potential Clinical Concern (PCC) The frequency of participant vital sign sitting blood pressure was obtained to check if the values lie outside of a pre-determined reference range (RR) for SBP 90-140 mmHg, DBP 50-90 mmHg or have a change from Baseline of PCC for SBP increase from Baseline (IFB) >=40, decrease from Baseline (DFB) >= 30 for and for DBP (IFB) >= 30 ,DFB >= 20. The number of participants with values of PCC at any time on treatment (ATOT) and follow up were reported. Up to 70 Weeks (including follow up)
Secondary Number of Participants With HR Values of PCC ATOT HR was measured once, after the participant sat quietly for at least 5 minutes. The frequency of participant vital sign heart rate was obtained to check if the values lie outside of a pre-determined reference range (RR) 50-100 bpm or have a change from Baseline of PCC IFB >=30 and DFB >=30. The number of participants with values of PCC including follow up were reported. Up to 70 Weeks (including follow up)
Secondary Number of Participants With BW Values of PCC ATOT The frequency of participant vital sign weight was obtained to check if the values have CFB of PCC IFB >=7 percent. With the exception of Week 4, when participants were first titrated to the 8mg RSG XR dose, at every time point in the study where weight was measured the percentage of participants experienced an increase in BW of PCC was approximately 2 times greater than the percentage of participants experiencing an decrease in BW of PCC DFB >=7 percent. The number of participants with values of PCC including follow up were reported. Up to 70 Weeks (including follow up)
Secondary Number of Participants With Hematology Parameters of PCC ATOT The hematology data included eosinophils, haematocrit, haemoglobin, lymphocytes, mean corpuscular haemoglobin (MCH), mean corpuscular volume (MCV), monocytes, platelet count, red cell distribution width (RDW), red blood cell (RBC) count, segmented neutrophils (SN), total neutrophils (TN), white blood cell (WBC) count. The number of participants with values of PCC (defined as high and low) ATOT were reported. Up to Week 82 (including follow up)
Secondary Number of Participants With Clinical Chemistry Parameters (Including Lipids) of PCC ATOT The clinical chemistry data included alanine amino transferase (ALT), albumin, aldolase, asparatate amino transferase (AST), BUN/creatinine ratio, carbon dioxide(CO2) content, chloride, cholesterol, creatinine kinase (CK), creatinine, direct bilirubin (DB), gamma glutamyl transferase (GGT), glucose, glycosylated Hemoglobin (HbA1C), HDL, LDL, lactate dehydrogenase (LD), magnesium, potassium, sodium, total bilirubin (TB), triglycerides, troponin I, urea. The number of participants with values of PCC (defined as high and low) ATOT were reported. Up to Week 82 (including follow up)
Secondary Change From Baseline in Alzheimer's Disease Assessment Scale - Cognitive (ADAS-cog) Total Score as a Function of Apolipoprotein E (APOE) e4 Status. The 11-item ADAS-Cog assessed a range of cognitive abilities including memory, comprehension, orientation in time and place and spontaneous speech. Most items were evaluated by tests, but some were dependent on clinician ratings on a five point scale. Scores ranged from 0 to 70 with higher scores indicating greater dysfunction. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication (Week 0). Change from Baseline was calculated as the Baseline value minus the value at the specified time point. Baseline (Week 0) and Week 24, 52
Secondary Change From Baseline in Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) Score as a Function of APOE e4 Status. The CDR-SB is a validated clinical assessment of global function in par. with Alzheimer's disease (AD). Impairment was scored in each of 6 cognitive categories on a scale in which none = 0, questionable = 0.5, mild = 1, moderate = 2, and severe = 3. The 6 individual category ratings, or box scores, were added together to give the CDR-Sum of Boxes which ranged from 0 to 18 (severe impairment). Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication (Week 0). Change from Baseline was calculated as the Baseline value minus the value at the specified time point. Baseline (Week 0) and Week 24, 52
Secondary Change From Baseline in Mini Mental State Examination (MMSE) Total Score as a Function of APOE e4 Status. The MMSE consisted of 11 tests of orientation, memory (recent and immediate), concentration, language and praxis. Scores ranged from 0 to 30, with lower scores indicating greater cognitive impairment. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication (Week 0). Change from Baseline was calculated as the Baseline value minus the value at the specified time point. Baseline (Week 0) and Week 24, 52
Secondary Change From Baseline in Disability Assessment for Dementia Scale (DAD) Total Score as a Function of APOE e4 Status. DAD, assessed the ability of a participant to execute basic and instrumental activities of daily living (ADL) and leisure activities. The scale consists of 40 questions assessing basic and instrumental ADLs. This scale assesses a participant's ability to initiate, plan, and perform activities related to hygiene, dressing, continence, eating, meal preparation, telephoning, going on an outing, finance and correspondence, medications, leisure, and housework. Each item was scored as yes: 1, no: 0 and N/A: not applicable. Higher scores indicate less disability with a score of 100 indicating no disability and 0 indicating no functional ability. The percentage score was calculated as (DAD total score/total number of applicable items) * 100. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication (Week 0). Change from Baseline was calculated as the Baseline value minus the value at the specified time point. Baseline (Week 0) and Week 24, 52
Secondary Change From Baseline in Neuropsychiatric Inventory (NPI) Total Score as a Function of APOE e4 Status. 12-domain caregiver assessment of behavioral disturbances occurring in dementia: delusions, hallucinations, agitation, depression, anxiety, euphoria, apathy, disinhibition, irritability, motor disturbance, appetite, nighttime behavior. A screening question is asked about each sub-domain. If the responses to these questions=participant has problems with a particular sub-domain of behavior, the caregiver asked all the questions about that domain, rating the frequency (1=occasionally to 4=very frequently) on a 4-point scale, their severity (1=Mild to 3=Severe) on a 3-point scale, and the distress on a 5-point scale. Total score=sum of each domain score(range 0-144);higher score=greater behavioral disturbances. Baseline for the open-label study was the latest assessment from Week 48 of parent studies to the first dose of open-label medication (Week 0). Change from Baseline was calculated as the Baseline value minus the value at the specified time point. Baseline (Week 0) and Week 24, 52
