Byetta Associated with Necrotizing Pancreatitis
September 1, 2008
Since issuing Information for Healthcare Professionals in October 2007, FDA has received reports of 6 cases of hemorrhagic or necrotizing pancreatitis in patients taking Byetta. Byetta is a medicine given by subcutaneous injection to help treat adults with type 2 diabetes. Of the 6 cases of hemorrhagic or necrotizing pancreatitis, all patients required hospitalization, two patients died and four patients were recovering at time of reporting. Byetta was discontinued in all 6 cases. Byetta and other potentially suspect drugs should be promptly discontinued if pancreatitis is suspected. There are no signs or symptoms that distinguish acute hemorrhagic or necrotizing pancreatitis associated with Byetta from the less severe form of pancreatitis. If pancreatitis is confirmed, initiate appropriate treatment and carefully monitor the patient until recovery. Byetta should not be restarted. Consider antidiabetic therapies other than Byetta in patients with a history of pancreatitis.
FDA has reviewed 30 postmarketing reports of acute pancreatitis in patients taking Byetta (exenatide), a drug used to treat adults with type 2 diabetes. An association between Byetta and acute pancreatitis is suspected in some of these cases. Amylin Pharmaceuticals, Inc. has agreed to include information about acute pancreatitis in the PRECAUTIONS section of the product label.
Healthcare professionals should be alert to the signs and symptoms of acute pancreatitis and instruct patients taking Byetta to seek prompt medical care if they experience unexplained, persistent, severe abdominal pain which may or may not be accompanied by vomiting. If pancreatitis is suspected, Byetta should be discontinued. If pancreatitis is confirmed, Byetta should not be restarted unless an alternative etiology is identified.

HPV Vaccine Associated with Serious Adverse Effects
August 30, 2008
As of June 30, 2008, there have been 9,749 VAERS reports of adverse events following Gardasil vaccination. Of these, 94% were classified as reports of non-serious events, and 6% as serious events.
Concerns have been raised about reports of deaths occurring in individuals after receiving Gardasil. As of June 30, 2008, 20 deaths had been reported to VAERS. There was not a common pattern to the deaths that would suggest they were caused by the vaccine. In cases where autopsy, death certificate and medical records were available, the cause of death was explained by factors other than the vaccine.
Guillain-Barre Syndrome (GBS) has also been reported in individuals following vaccination with Gardasil. GBS is a rare neurological disorder that causes muscle weakness. It occurs spontaneously in unvaccinated individuals after a variety of specific infections. FDA and CDC have reviewed the reports of GBS that have been submitted to VAERS. To date, there is no evidence that Gardasil has increased the rate of GBS above that expected in the population. While FDA continues to carefully analyze all reports of GBS submitted to VAERS, the data do not currently suggest an association between Gardasil and GBS.
Thromboembolic disorders (blood clots) have been reported to VAERS in people who have received Gardasil. Most of these individuals had risk factors for blood clots such as use of oral contraceptives which are known to increase the risk of clotting. Thromboembolic disorders as well as other medical events are being studied through the VSD in previously planned controlled studies. The manufacturer has also committed to conduct a large postmarketing study to further assess the vaccine’s safety.

Profits Before People: Merck and Schering-Plough Caught Red handed
April 1, 2008
Emails between a Schering-Plough executive and the principle investigator of the ENHANCE trial were made public today by Sen. Chuck Grassley. The emails reveal that the ENHANCE trial’s principal investigator perceived that the drugmakers were withholding unfavorable results about ezetimibe/simvastatin (Vytorin) for non-scientific reasons. (Surprise Surprise). Instead of releasing the bad data, Sen. Grassley noted, Merck/Schering-Plough went on a marketing blitz to increase Vytorin prescriptions.

Dietary Supplements with Dangerous Ingredients
March 21, 2008
Palo Alto Labs and FDA notified consumers and healthcare professionals of a voluntary nationwide recall of two dietary supplements, Aspire36 and Aspire Lite. The products were recalled because they were found to contain Aildenafil in trace amounts and Dimethyl sildenafil thione, an analog of Sildenafil, a drug used to treat erectile dysfunction. The presence of these ingredients in the dietary supplements may pose a threat to consumers because the analogue may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may lower blood pressure to dangerous levels. Consumers who have Aspire36 and Aspire Lite in their possession should stop using the products and return any unused product to the place of purchase.

Tamiflu associated with Changes in Behavior
March 20, 2008
Roche and FDA informed healthcare professionals of neuropsychiatric events associated with the use of Tamiflu, in patients with influenza.The label has been revised as follows: Influenza can be associated with a variety of neurologic and behavioral symptoms which can include events such as hallucinations, delirium, and abnormal behavior, in some cases resulting in fatal outcomes. These events may occur in the setting of encephalitis or encephalopathy but can occur without obvious severe disease. There have been postmarketing reports (mostly from Japan) of delirium and abnormal behavior leading to injury, and in some cases resulting in fatal outcomes, in patients with influenza who were receiving Tamiflu. Because these events were reported voluntarily during clinical practice, estimates of frequency cannot be made but they appear to be uncommon based on Tamiflu usage data. These events were reported primarily among pediatric patients and often had an abrupt onset and rapid resolution. The contribution of Tamiflu to these events has not been established. Patients with influenza should be closely monitored for signs of abnormal behavior. If neuropsychiatric symptoms occur, the risks and benefits of continuing treatment should be evaluated for each patient.

Spiriva HandiHaler Associated with Possible Increase in Stroke
March 20, 2008
Boehringer Ingelheim and FDA notified healthcare professionals that ongoing safety monitoring has identified a possible increased risk of stroke in patients who take Spiriva. This product contains tiotropium bromide and is used to treat bronchospasm associated with chronic obstructive pulmonary disease. Boehringer Ingelheim reported to the FDA that it has conducted an analysis of the safety data from 29 placebo controlled clinical studies (“pooled analysis”). Based on data from these studies, the preliminary estimates of the risk of stroke are 8 patients per 1000 patients treated for one year with Spiriva, and 6 patients per 1000 patients treated for one year with placebo. This means that the estimated excess risk of any type of stroke due to Spiriva is 2 patients for each 1000 patients using Spiriva over a one year period.
It is important to interpret these preliminary results with caution. FDA is working with Boehringer Ingelheim to further evaluate the potential association between Spiriva and stroke. FDA has not confirmed these analyses and while pooled analyses can provide early information about potential safety issues, these analyses have inherent limitations and uncertainty that require further investigation using other data sources. Patients should not stop taking Spiriva HandiHaler before talking to their doctor, if they have questions about this new information.

Prezista causes Hepatitis
March 12, 2008
FDA and Tibotec Therapeutics notified healthcare professionals of changes to the WARNINGS section of the prescribing information for Prezista (darunavir) tablets regarding the risk of hepatotoxicity. In clinical trials and postmarketing experience, drug induced hepatitis has been reported in patients receiving combination therapy with Prezista/ritonavir. Appropriate laboratory testing should be conducted prior to initiating therapy with Prezista/ritonavir and patients should be monitored during treatment. Increased AST/ALT monitoring should be considered in patients with underlying chronic hepatitis, cirrhosis, or in patients who have pretreatment elevations of transaminases, especially during the first several months of Prezista/ritonavir treatment.
