FDA Approves Cyberonics' VNS Therapy™ System for Treatment-Resistant Depression (TRD)

Friday July 15, 4:53 pm ET
First FDA-Approved Treatment Specifically for TRD; First Implantable Device-Based Treatment for Depression


Conference Call Scheduled for Monday, July 18 at 8:00 AM EDT; Investor/Analyst Day at Cyberonics Scheduled for July 25-26


HOUSTON, July 15 /PRNewswire-FirstCall/ -- Cyberonics, Inc. (Nasdaq: CYBX - News) today announced that the United States Food and Drug Administration (FDA) approved the Vagus Nerve Stimulation (VNS) Therapy System "for the adjunctive long-term treatment of chronic or recurrent depression for patients 18 years of age or older who are experiencing a major depressive episode and have not had an adequate response to four or more adequate antidepressant treatments." VNS Therapy is delivered from a small pacemaker-like generator implanted in the chest that sends preprogrammed, intermittent, mild electrical pulses through the vagus nerve in the neck to the brain. The VNS Therapy System is the first FDA-approved implantable device-based treatment for depression and the first treatment developed, studied, approved and labeled specifically for patients with treatment-resistant depression (TRD). The VNS Therapy System was approved as a treatment for medically refractory epilepsy in Europe in 1994 and in the United States and Canada in 1997 and as a treatment for TRD in Europe and Canada in 2001. Over 32,000 patients worldwide have accumulated over 94,000 patient years of experience with the VNS Therapy System. The VNS Therapy System is now commercially available for the treatment-resistant depression and refractory epilepsy approved uses in the United States, European Union and Canada. For more information on VNS Therapy for treatment- resistant depression, including the contraindications, warnings and precautions, see the Physician's and Patient's Manuals and other information at http://www.cyberonics.com or http://www.vnstherapy.com or call 1-877-NOW 4 VNS.

FDA APPROVES MEDICAL DEVICE FOR EPILEPSY

The FDA today approved the first medical device to help
reduce seizures in people with epilepsy who have severe,
uncontrolled seizures.
The approval came just 19 days after the positive
recommendation of the Neurological Devices Panel of FDA's
Medical Devices Advisory Committee. FDA received an application
to market the product on Jan. 27 and expedited its review
because of its potential importance for reducing seizures in
people who lack effective, alternative treatment.
The device, called a vagus nerve stimulator, consists of a
generator which is implanted under the collar bone like a
pacemaker and connected by wire to the vagus nerve in the neck
where it delivers electrical signals to the brain to control
seizures. It includes an external programming system which is
used by the physician to change stimulation settings. Patients
can turn the stimulator on and off with a hand-held magnet by
holding it over the stimulator.
The NeuroCybernetic Prosthesis System, made by Cyberonics,
of Houston, was approved for use in conjunction with drugs or
surgery in adults and adolescents with partial onset seizures,
the type of seizures that begin in one part of the brain and may
remain localized or become generalized to the entire brain.
"Vagus nerve stimulators offer people with uncontrolled
seizures a new type of treatment," said Bruce Burlington,
director of FDA's Center for Devices and Radiological Health.
"While this device will not help everyone, it will reduce the
frequency of seizures in many people."
Approximately 1.7 million Americans have epilepsy. Most
seizures can be controlled by medication. However, about 200,000
people have seizures that cannot be fully or adequately
controlled with drugs or surgery. Severe, ongoing seizures can
lead to death.
FDA's approval of the device was based on a review of
clinical studies on safety and effectiveness submitted by the
manufacturer and on the recommendation of the Neurological
Devices Panel.
In the studies, the device was implanted in 454 patients
with poorly controlled seizures at 45 medical centers in the
United States, Canada and Europe. The patients continued to take
anti-seizure medication during the study.
In the most recent study, most patients showed at least some
improvement with the vagus nerve stimulator. Half the patients
treated had at least a 20 percent reduction in the number of
seizures per day. In about 1 in 4, the frequency of seizures

decreased by more than 50 percent. In about 1 in 5, however, the
number of seizures actually increased.
Side effects during stimulation included cough (50%),
hoarseness (100%), voice alteration (73%), and shortness of
breath (25%). However, these side effects were considered
tolerable by most patients.
Nine patients died during the studies, but none of the
deaths were believed by the clinical investigators to be caused
by the device. Four deaths were classified as Sudden Unexpected
Death in Epilepsy. The others resulted from drownings,
pneumonia, liver failure and blood disease.
Although the death rate was not statistically higher than
that expected for people with severe, poorly controlled seizures,
FDA has asked Cyberonics to continue to provide detailed
information about any further deaths, particularly any sudden
unexpected deaths. The agency has also asked the company to
further evaluate its study data to find out whether any factors
predict which patients are the most likely and least likely to
benefit from use of the device.

RE: FDA, Cyberonics

Senate Finance Committee Chairman Chuck Grassley and Ranking Member Max
Baucus issued the following comment this afternoon.

"The Finance Committee will continue its inquiry into the Food and Drug Administration's consideration of the pre-market approval supplement for the  vagus nerve stimulator to be used for depression that is treatment-resistant. Both the effectiveness and the safety of medical devices must be ensured prior to their approval by the Food and Drug Administration."
QUOTE
Statement of Peter Lurie, MD, MPH, Deputy Director, Public Citizen’s Health Research Group

The decision by the U.S. Food and Drug Administration (FDA) to approve the Vagus Nerve Stimulator (VNS) for treatment-resistant depression is one of its most questionable regulatory decisions made by the agency in recent memory. As a consequence of the FDA’s data-free decisionmaking, hundreds of thousands of patients with severe depression are likely to undergo surgery to implant a device that has not been proved to work.
QUOTE
Dr. Richard P. Malone, who served on the expert panel that scrutinized the VNS data, said he was not convinced the device met the agency's standard for a reasonable assurance of safety or efficacy.

"I would hope approval meant for a treatment in psychiatry that there were clear data (showing) it is or isn't effective," Malone told United Press International. "If (receiving) an official approval it would have been shown to be effective in well designed studies -- this wasn't."

Looks like Senator Chuck Grassley, Chairman of the Senate Finance Committee is not fond of Dr. Lester Crawford's work:

Floor Statement of U.S. Senator Chuck Grassley of Iowa
Nomination of Dr. Lester Crawford to Commissioner of the Food and Drug Administration
Monday, July 18, 2005


I rise to address the nomination of Dr. Lester Crawford to be Commissioner of the Food and Drug Administration. I have considered Dr. Crawford’s experience and performance on the job for well over a year now. In fact, Dr. Crawford has been the man in charge at FDA since I began taking a hard look at the FDA. It has been a long year for the FDA, and I have taken a long look at Dr. Crawford’s efforts to address FDA’s problems.

I know Dr. Crawford is intimately familiar with how the FDA operates. He has twice served as acting Commissioner, most recently since March 2004, and his lengthy service at the FDA is commendable. Dr. Crawford and I have met on a couple occasions. He seems to have the best of intentions. He told me personally that he understands there are problems at the FDA that need to be fixed. I believed at one point that he was capable of fixing those problems. However, as the saying goes, “the proof is in the pudding.” Today, I am here to say that I cannot vote for
Dr. Crawford to be the next Commissioner of the FDA.

During the last 18 months, this country’s confidence in the FDA has been shaken. It has been shaken not because of one isolated incident or one isolated whistleblower. It has been shaken because multiple drug safety concerns have been exposed by more than one courageous whistleblower. My oversight of the FDA leads me to the conclusion that there are cultural and systemic problems at the FDA. Unfortunately, Dr. Crawford has long been part of that same culture and system. The evidence is overwhelming that the FDA must change to better protect the American people. Dr. Crawford does not appear willing to be the man to change the FDA.

During Dr. Crawford’s tenure, I have witnessed the suppression of the scientific process and the muzzling of scientific dissent. First, with Dr. Mosholder finding a link between anti-depressants, children and suicide. And second with Dr. Graham’s allegations regarding the FDA, Vioxx and post-marketing safety generally. Dr. Graham’s testimony before the Finance Committee suggests that the problems are systemic. Oversight of the FDA exposed the cozy relationship that exists between the FDA and the drug industry. It revealed that the FDA negotiated for almost two years with Merck about how to change the Vioxx label so people would know about the risk of heart attacks.

But the problems are not isolated to the Center for Drug Evaluation and Research. My staff continues to interview FDA staff across the agency, employees who are doing important work on drugs, devices, and biologics. It is becoming more and more obvious to me that FDA is plagued by structural, personnel, cultural, and scientific problems. Those problems should be equally obvious to Dr. Crawford. But under the leadership of Dr. Crawford, the FDA appears to be in a state of denial. Over the past 18 months, Dr. Crawford has not stepped up to the plate. I have seen no recognition of the depth and breadth of the problems at the FDA. I have only seen a few short-term band-aids.

The systemic problems at the FDA demand visionary leadership. Dr. Crawford has not shown me that he is the leader to fix the FDA.

Is the VNS generator classified as a pacemaker? If so, this might apply:
QUOTE
Dear Dr. Crawford:

The Committee on Finance (Committee) has jurisdiction over the Medicare and Medicaid programs, among other matters. Accordingly, the Committee is responsible to the more than 80 million Americans who receive health care coverage under those programs, including payment for medical devices.

Today, Guidant Corporation (Guidant) issued a press release entitled, “Guidant Initiates Worldwide Physician Communications Regarding Important Safety Information and Corrective Action about Certain Pacemakers.” Guidant’s action today, which the company says the Food and Drug Administration (FDA) may classify as a recall, comes on the heels of recalls for several other Guidant devices, specifically Implantable Cardiac Defibrillators.

As Chairman of the Committee, I request that the FDA provide the Committee with copies of the past five annual postapproval reports—required under 21 C.F.R. 814.84—for all pacemakers and defibrillators associated with Guidant’s device warnings, issued on May 25, June 17, June 24 and July 18, 2005. In addition, it is my understanding that the FDA does not presently make all device manufacturers’ annual postapproval reports publicly available, despite the fact that the reports contain important performance data. Among other detailed information, pacemaker and defibrillator manufacturers must report to the FDA the number of patient deaths, analyses of failure mechanisms, and other safety and effectiveness issues. Given the importance of such information to health care providers and the scientific community, state why the FDA should not proactively post such information in the FDA’s electronic reading room. In addition, describe in detail the FDA’s disclosure policy with respect to post approval-related documents for devices, including but not limited to pacemakers and defibrillators.
