Several respected researchers think that Alzheimer’s dementia may primarily be an infectious disease, particularly related to gum bacteria.
LOS ANGELES — As more disappointing results emerge from anti-amyloid drug trials in Alzheimer’s disease (AD), there is growing interest in novel treatment approaches for this condition.
One such approach is based on the hypothesis that Porphyromonas gingivalis (Pg), the bacteria involved in periodontal disease, may cause AD. The biopharmaceutical company Cortexyme Inc is testing this theory with an investigational agent COR388, which targets gingipains, the toxic proteases released by Pg. Early results show the drug is well tolerated and promising in terms of biomarker findings. Organizers hope that a phase 2/3 trial of the treatment now under way will provide definitive efficacy results.
