Dear Sandra Zhuoli,
I hope this letter finds you well. I understand that you recently requested information on early access to dexpramipexole from our medical information department. Therefore, I wanted to respond directly to your request and explain Biogen Idec’s situation regarding this investigational agent for the treatment of amyotrophic lateral sclerosis (ALS).
As you know, ALS is a devastating disease with, as of yet, no optimal therapies or cure. Biogen Idec is focused on the urgent concerns of patients with this fatal and rapidly progressive disease and we are committed to advancing dexpramipexole as quickly as we can. Our ultimate goal is to achieve regulatory approval of dexpramipexole so that all eligible patients may have equitable access to treatment. Rigorous and well conducted clinical trials are required to achieve this goal.
The safety and efficacy of dexpramipexole for the treatment of ALS is currently under evaluation in a large Phase III clinical trial (223AS302, ‘EMPOWER’; recruitment complete).
Unfortunately, at this time, we cannot make dexpramipexole available outside of a well-controlled clinical trial setting. This was a deeply considered decision for our company based on the following:
• The efficacy of dexpramipexole was only suggested, not determined, by the Phase II study.
• There are examples of recent clinical trials in ALS in which experimental therapies actually worsened outcomes for patients, despite earlier hopeful signals.
• Long-term safety of dexpramipexole in a large population of ALS patients has not been fully established and the potential risks of the drug have not been adequately identified.
• Above all, we must not harm patients and their families by allowing access to a drug that has not been proven safe or by encouraging false hope with a drug that has not been proven effective.
Our position has been discussed with prominent experts, including bioethicists, regulators, and patient advocacy groups – all of whom support our decision. However, we also recognize that our reasons for delaying an early access program for dexpramipexole may seem inadequate to a patient or a loved one; unfortunately, they are essential to fulfilling our obligations and mission of advancing a meaningful treatment for the benefit of all ALS patients as rapidly as possible. Please let me know if you have any additional questions.
Yours sincerely,
Sarah Kulke, MD
