Medivation Dimebon Connection Study Complete, Additional Phase 3 Trials Still Open


Medivation, Inc. (MDVN) today announced the completion of patient enrollment in the CONNECTION study, a six-month, confirmatory, pivotal Phase 3 trial of the investigational drug dimebon in patients with mild-to-moderate Alzheimer's disease.
The following Dimebon Clinical Phase Three Clinical Trials are open to new participants or scheduled to open.

A Phase 3 Study To Evaluate The Safety And Tolerability Of Dimebon Patients With Mild To Moderate Alzheimer's Disease
  • If on existing anti-dementia therapy, have been on a stable dose of anti-dementia therapy (cholinesterase inhibitors and/or memantine) for at least 60 days prior to dosing in study.
  • If not taking existing anti-dementia therapy, have not received therapy with cholinesterase inhibitors and/or memantine within 60 days prior to dosing in this study.
Safety and Efficacy Study Evaluating Dimebon in Patients With Mild to Moderate Alzheimer's Disease on Donepezil (CONCERT)
  • Stable on donepezil (Aricept) for at least 6 months
An Efficacy Study Of Dimebon In Patients With Moderate To Severe Alzheimer's Disease (now open and recruiting new participants)
  • Have been taking the medication memantine (ie., Namenda) for at least six months prior to this study.
  • Must have a caregiver who assists the patient at least five days per week for at least three hours per day, who can accompany patient to study visits, and who has an intimate knowledge of the patient's health states and personal care.
  • Note exclusion criteria: Have taken medicines for Alzheimers disease other than memantine (e.g., donepezil, rivastigmine, galantamine, tacrine) within 2 months prior to this study.

Medivation Completes Enrollment in Confirmatory, Pivotal Phase 3 'CONNECTION' Trial of Dimebon in Patients With Alzheimer's Disease

Medivation, Inc. (Nasdaq: MDVN) today announced the completion of patient enrollment in the CONNECTION study, a six-month, confirmatory, pivotal Phase 3 trial of the investigational drug dimebon in patients with mild-to-moderate Alzheimer's disease.

The international, double-blind, placebo-controlled, pivotal Phase 3 study enrolled 598 patients, exceeding the enrollment target of 525 patients. More than 40 percent of the patients enrolled were in the United States. The six-month study is evaluating the effect of dimebon on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and the Clinician's Interview-Based Impression of Change plus caregiver interview (CIBIC-plus) -- the two endpoints have historically been accepted by the U.S. Food and Drug Administration (FDA) to support registration of currently approved drugs for mild-to-moderate Alzheimer's disease.

"Completion of patient enrollment in this second pivotal trial moves us closer to our goal of submitting a marketing application to the FDA and bringing dimebon to market for the many Alzheimer's patients suffering from this devastating disease," said Lynn Seely, M.D., chief medical officer of Medivation. "We are gratified by the strong interest in this trial as indicated by our exceeding the enrollment goal. Together with our partner Pfizer, we are executing a comprehensive clinical plan to support an NDA filing, currently targeted for 2011, with a broad and differentiated label for dimebon in Alzheimer's disease. We are also conducting a Phase 3 safety study, which will provide us and Pfizer the opportunity to seek marketing approval earlier if results of the CONNECTION study confirm our previously completed first pivotal study, which was published in the Lancet last year."

About Dimebon

Dimebon is an investigational compound currently in Phase 3 development for the treatment of Alzheimer's disease and in clinical development for Huntington disease. In preclinical models of Alzheimer's disease and Huntington disease explored thus far, dimebon has been shown to inhibit brain cell death, potentially by stabilizing and improving mitochondrial function in a way that prevents neuron death and dysfunction. The dimebon mechanism is thought to be distinct from that of currently available Alzheimer's disease medications.

In addition to CONNECTION, dimebon is being studied in the 12-month Phase 3 CONCERT trial, which is evaluating the efficacy of dimebon when added to ongoing treatment with donepezil (Aricept(R)) in patients with mild-to-moderate Alzheimer's disease, and in a Phase 3 safety study. Two Phase 3 studies in moderate-to-severe Alzheimer's disease are also planned to start this year.

In Huntington disease, a Phase 2 study has been completed. Medivation and Pfizer expect to initiate a Phase 3 trial this year to evaluate the potential benefits of dimebon on cognition in patients with Huntington disease.
