NewGam/Octagam® is an intravenous immunoglobulin preparation by the Switzerland-based company Octapharma. It is a marketed product. The rationale of evaluating it in Alzheimer's disease, as for other intravenous immunoglobulin preparations such as Gammagard® and Flebogamma, is that naturally occurring polyclonal autoantibodies against Aβ may be protective and are reduced in Alzheimer's disease (see Weksler et al., 2002).


The first trial of this IVIG preparation in Alzheimer's evaluated six different doses of Octagam 10 percent against two placebo comparators in a six-month trial of 58 people with mild to moderate AD. This multicenter Phase 2 trial has been completed. This trial missed its primary endpoint of change in plasma Aβ levels, and was negative for most of its secondary biomarker outcomes with the exception of a signal suggesting a benefit for cerebral metabolism. None of the doses tested showed any benefit for cognition or function (see Dodel et al, 2013; Feb 2013 news).

A second, single-center Phase 2 study conducted at Sutter Institute for Medical Research in Sacramento, California, investigated the long-term effects of a short course of this IVIG preparation. Octagam 10 percent was infused every other week for two months in 50 people with amnestic MCI due to AD, with two years of follow-up. Initial results on 28 patients assessed one year after treatment indicated possible effects on the Clinical Dementia Rating Sum of Boxes and brain atrophy as seen on MRI (see Mar 2013 conference story). Full publication of the data reported less brain atrophy and a treatment benefit on ADAS-cog13 and MMSE in the IVIG group compared to the placebo group at 12 months; these differences disappeared by 24 months. The paper also reported a trend toward fewer progressions to AD dementia in the treated group at 12 months, and argued for additional research on this approach (Kile et al., 2015).

In October 2015, the pipeline page of Octapharma Canada still mentions Alzheimer's and mild cognitive impairment as a focus of its Octagam program, but no trials were listed.
