FDA approves weight-loss drug Contrave (Replace)
September eleven, 2014 by Matthew Perrone
U.S. regulators have greenlighted a new weight-loss drug known as Contrave, the third in a string of approvals for prescription drugs aimed on the nation's 78 million obese adults.
The tablet, Contrave, is a combination of two medicine which can be already accepted, naltrexone and bupropion. Naltrexone is used to treat alcohol and narcotic dependence. Bupropion is an antidepressant additionally used to help people give up smoking.
Contrave joins two similar medicine from Arena Pharmaceuticals and Vivus Inc. which FDA approved in 2012 after a 13-year drought of recent prescription weight-loss medicines. Analysts initially predicted those medication would garner up to $1 billion in annual gross sales, contemplating that multiple-third of all U.S. adults are overweight. However gross sales of Vivus' Qsymia and Arena's Belviq have been far beneath expectations attributable to limited insurance coverage protection and high out-of-pocket prices for sufferers.
Dr. Ronald Tamler of Mount Sinai Hospital's diabetes middle says he prescribes weight loss drugs solely when patients have failed to shed extra pounds via lifestyle modifications. Even then, he says insurers are reluctant to cowl the medicines.
"With any of these weight-loss medications, the minute you stop taking it, you begin regaining the load," Tamler mentioned. "Which means the affected person is dealing with a life of being on medicine, which isn't enticing for sufferers or third-party payers."
Contrave was developed by Orexigen Therapeutics Inc., primarily based in La Jolla, California. The Food and Drug Administration mentioned Thursday that it's permitted to be used by people who have a physique mass index of 30 or larger, which is the extent at which people are considered to be overweight. It's also authorized to be used by individuals with a BMI of 27 or greater who also have a weight-associated medical condition corresponding to diabetes.
The company accepted the drug for use in combination with a reduced-calorie diet and exercise.
Consultants say patients have to have reasonable expectations about how a lot weight they will lose by taking a tablet. Sufferers on Contrave for a yr misplaced four.2 percent more weight than sufferers taking a dummy pill.
That compares with weight reduction between three % and three.7 p.c for Belviq and 6.7 percent to eight.9 percent for Qsymia, both additionally measured in opposition to placebo.
Drug-induced weight loss is much smaller than that seen with surgical procedures, equivalent to gastric bypass, which might produce a 25 percent to 30 percent drop in weight, on common.
Docs who treat obesity say they use medicine like Contrave as an opportunity to coach patients on choosing a healthier, low-calorie weight loss plan.
Contrave will have a boxed warning concerning the danger of suicidal ideas associated with antidepressants like Bupropion.
Consultants warning that potentially dangerous drug interactions are a risk with the brand new era of weight-loss medication.
"Physicians prescribing these brain medications must evaluate patients different medications as a result of they're continuously on antidepressants and there is an interaction," mentioned Tamler.
Further Contrave risks embrace the potential of seizures, as well as increased blood stress and coronary heart rates.
The heart results created a long road to approval for Contrave. The FDA refused to approve the drug in 2011, citing cardiovascular dangers. Orexigen resubmitted its utility to regulators in December, saying that the drug fared properly in an early analysis of a study designed to rule out excessive cardiovascular threat.
Contrave may have an uphill battle within the U.S. market after the disappointing performance of rival therapies from Vivus Inc. and Area Prescribed drugs Inc. In the most recent quarter Vivus reported sales of $11 million for Qsymia, whereas Area Prescribed drugs reported $9.9 million in Belviq sales.
Contrave will be distributed within the U.S. by Japanese drugmaker Takeda Prescribed drugs, which will pay Orexigen royalties on gross sales. Orexigen and Takeda plan to begin promoting the drug this fall.
Shares of Orexigen Therapeutics Inc. fell fifty one cents, or 8.6 p.c to $5.39 in trading.
