Dimebon (latrepirdine)

Medivation, in collaboration with Pfizer, is currently evaluating dimebon in both Alzheimer’s and Huntington diseases in multiple clinical trials. We have completed enrollment in the confirmatory Phase 3 CONNECTION trial of dimebon in patients with mild-to-moderate Alzheimer’s disease. The Phase 3 CONCERT study, which is currently enrolling patients, is evaluating dimebon in patients already treated with donepezil, the leading Alzheimer’s disease medication worldwide. We have completed enrollment in a safety trial of patients with Alzheimer’s disease on a variety of anti-dementia medications to help meet international safety database requirements. The Phase 3 CONSTELLATION and CONTACT trials are evaluating dimebon in patients with moderate-to-severe disease.

In addition, we are currently enrolling patients in an international safety and efficacy Phase 3 trial known as HORIZON in patients with mild-to-moderate Huntington disease. To read about the study results from our Phase 2 trial of dimebon in Huntington disease, please click here.
