Cyberonics is unable to get partner for its depression therapy; vagus nerve stimulation ( VNS).
Today Cyberonics Inc., the manufacturer of the vagus nerve stimulator, announced some very disappointing, but not surprising news:
We are in the fourth-year of FDA approval of vagus nerve stimulation therapy to treat major depressive disorder. In May of 2007, The Centers for Medicare and Medicaid Services concluded that vagus nerve stimulation was not necessary to treat resistant depression, issued a final and binding National Coverage Decision of no coverage.
For current VNS patients, the Company did announce "we remain committed to supporting patients and clinical partners." That is the good news. If you or a loved one currently has the implant for depression, please do not worry. The President and Chief Executive of Cyberonics Inc., Daniel Moore, has made it clear that you will continue to receive appropriate medical and clinical support.
It is also important to remember that Cyberonics is fully committed to its very profitable epilepsy business. The procedure for depression is identical to that of the procedure for epilepsy. The device is identical, the surgery is identical and the programming of the device is identical.
Cyberonics employs over 440 people, has implanted 52,000 patients( epilepsy and depression) nationwide and has relationships with doctors in all fifty states. In the short term, this news is not really news. In the very long term, this news may ultimately be the catalyst for a much larger Company to conduct another trial for treatment-resistant depression--- a large, very well designed, double-blind, placebo-controlled with a long acute( blinded) period. Ideally I think the "blinded" portion of any future trial should be nine months.
For many patients( including me), there is a dramatic improvement in mood and depression that "kicks-in" after six months of stimulation. The design of the original trial had only an eight week fixed dosage of VNS, which apparently was one of the reasons for the less than stellar results reported during the acute( short-term) portion of the trial. Secondly, scientists are currently researching dosing strategies as well as methods to determine appropriate patients for VNS Therapy(TM).
More on this tomorrow.
