- Lead Sponsor
- Baxalta now part of Shire
- Brief Summary
The purpose of this long-term study is to provide additional evidence of safety and efficacy of IGIV, 10% treatment in participants with Alzheimer´s Disease who have completed the Phase 3 Baxter precursor study 160701. All participants will receive IGIV, 10% at either 0.2 g/kg or 0.4 g/kg body weight depending on their treatment assignment in Baxter study 160701. Participants and investigators will be blinded to dose unless otherwise notified by the sponsor.

Group Intervention Description IGIV, 10% at 0.4 g/kg body weight Immune Globulin Intravenous (Human), 10% (IGIV, 10%) IGIV, 10% at 0.4 g/kg body weight every 2 weeks for up to 3 years, 6 months IGIV, 10% at 0.2 g/kg body weight Immune Globulin Intravenous (Human), 10% (IGIV, 10%) IGIV, 10% at 0.2 g/kg body weight every 2 weeks for up to 3 years, 6 months.
- Primary Outcome Measures
Name Time Method Number and Severity of Treatment-emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) 6 months Number of Infusions Causally Associated With Adverse Events (AEs) and Serious Adverse Events (SAEs) 6 months Number of Infusions Temporally Associated With Adverse Events (AEs) and Serious Adverse Events (SAEs) 6 months Number of Infusions Discontinued, Slowed or Interrupted Due to an Adverse Event (AE) or Serious Adverse Event (SAE) 6 months
- Secondary Outcome Measures
Name Time Method Neuropsychiatric Inventory (NPI) Score 6 months The NPI is a validated instrument used to assess behavioral psychopathology in Alzheimer's Disease; it evaluates the frequency and severity of 12 neuropsychiatric features including delusions, hallucinations, dysphoria, anxiety, agitation/aggression, euphoria, disinhibition, irritability/lability, apathy, aberrant motor activity, sleep and night-time behavior change, and appetite and eating change. The NPI total score ranged 0-144, with higher scores indicating greater impairment.
Mini Mental State Examination (MMSE) 6 months The MMSE is a test for cognitive dysfunction. The test provides a 30-point composite rating for spatial and temporal orientation, verbal recall, simple attention, working memory, naming, repetition, comprehension, writing and constructional abilities. The total score can range from 0 to 30 with a higher score indicating better function.
Alzheimer's Disease Cooperative Study (ADCS) - Activities of Daily Living (ADL) Inventory (ADCS-ADL/ ADCS-ADL-severe) 6 months The ADCS-ADL scale is a validated tool to assess instrumental and basic activities of daily living based on a 23 item structured interview of the caregiver or qualified study partner. Scores on the ADCS-ADL range from 0-78 with lower scores indicating greater impairment; hence decreases from baseline reflect potential functional deterioration.
Logsdon Quality of Life in Alzheimer's Disease (QOL-AD) 6 months The QOL-AD is a validated, 13-item instrument developed specifically for individuals with dementia. The assessment rates the participant's quality of life for physical, emotional, interpersonal, and environmental domains. The QOL-AD total score ranged 13-52. Lower scores on the QOL-AD are associated with a lower quality of life.
EQ-5D Questionnaire (Proxy Version) 6 months EQ-5D is a participant answered questionnaire scoring 5 dimensions - mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The EQ-5D total score ranges from 0 (worst health state) to 1 (perfect health state) and 1 reflects the best outcome. The EQ-5D also includes a standard vertical 20 cm visual analogue scale (VAS) ranging from best imaginable health state \[100\] to worst imaginable health state \[0\]. Caregivers are asked to describe how they believe a participant would rate his/her health state that day.
Time to Skilled Nursing Facility Placement 6 months Time to skilled nursing facility placement is defined as permanent admission to a skilled nursing facility. Time will be defined as the number of months between enrollment into this clinical study and placement in a skilled nursing facility placement.
Total Score of the Cognitive Subscale of the Severe Impairment Battery (SIB) 6 months The SIB is a 40-item psychometric assessment that is composed of simple one-step commands combined with gestures. The scoring range is from 0 to 100 with a lower score indicating greater cognitive impairment.
Healthcare Resource Utilization Questionnaire (HRUQ) 6 months The HRUQ determines if there is a difference in healthcare utilization and health-related expenditures, most notably nursing home (ie, skilled nursing facility) admissions, when subjects are treated with study product. This assessment is performed with the primary caregiver. This assessment is descriptive and does not contain specific scores.
Total Score of the Cognitive Subscale of the Alzheimer's Disease Assessment Scale (ADAS-Cog) 6 months The ADAS-Cog is a validated psychometric instrument that evaluates memory (word recall, word recognition), attention, reasoning (following commands), language (naming, comprehension), orientation, ideational praxis (placing letter in envelope) and constructional praxis (copying geometric designs). This test was administered by experienced raters certified by Alzheimer's Disease Cooperative Study (ADCS) at the site. Scores on the ADAS-Cog range from 0-70 with higher scores indicating greater impairment.
Caregiver Burden Questionnaire 6 months The Caregiver burden questionnaires is a self-administered questionnaire that has been developed to measure the emotional, physical, and social impact of caregiving on Alzheimer's Disease caregivers. A Total score is calculated from this measure by summing the responses across the items. The Total score may range from 9-45, with higher scores indicating greater burden.
Volumetric MRI 6 months Volumetric MRI measurements were obtained to assess rate of whole brain atrophy and ventricular enlargement. Additional volumetric measurements may be analyzed when specific hypotheses and methods are defined. Additional volumetric MRI analysis may include (but may not be limited to) one or more of the following: rate of hippocampal atrophy, entorhinal cortical thickness, and/or regional cortical thinning.
