Orexigen Therapeutics, Inc. (OREX) surges on news of obesity drug revival

Wednesday, September 21st, 2011

Shares of Orexigen Therapeutics, Inc. (Nasdaq: OREX) surged more than 80 percent from Tuesday’s closing price in morning trading on Wednesday after the company, along with the U.S. Food and Drug  Administration identified “a clear and feasible path to approval for Contrave,” Orexigen’s experimental obesity drug that was shelved  earlier this year because of health risks.

“We have been working with clinical experts, advocacy groups, and our partner, Takeda, throughout this process and are pleased with the feedback provided by FDA that identified a very clear and feasible path forward for this important therapy,” said Michael Narachi, President and CEO of Orexigen in a September 21 press release.

Shares of Orexigen touched a high of $2.68, up from Tuesday’s closing price of $1.47, according to Yahoo Finance.

Contrave, an investigational combination therapy of naltrexone HCl and bupropion HCl, was studied for its ability to help people with obesity initiate and sustain weight loss of at least 5 percent of their starting body weight in one year. Contrave was submitted for U.S. regulatory approval in March 2010. The original submission was based on multiple clinical trials that evaluated Contrave in more than 4500 patients.

Orexigen Therapeutics and its Japanese partner Takeda will need to run a  patient safety study of approximately 10,000-patients to assess the heart-safety risk of Contrave.

Orexigen estimates that the entire study would require less than 10,000 patients and less than two years from study start to the interim analysis, according to the September 21 press release. Orexigen plans to meet with the review division to finalize a protocol with the objective of initiating the CVOT in the first half of 2012, with potential approval in 2014.

Arena Pharmaceuticals, Inc. (ARNA) – Buzz Stock of the Day

Friday, July 16th, 2010

We first featured Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) on July 1, after the company announced a U.S. marketing deal for its obesity treatment, lorcaserin. Since then, shares have continued their climb, surging almost 20 percent in pre-market trading on Friday after it was announced that an FDA panel voted 9-7 against clearing a competing experimental weight loss drug developed by Vivus, Inc. for marketing in the U.S.

Panelists unanimously agreed the drug helps patients lose pounds, with most reporting more than 10 percent weight loss. But those benefits were outweighed by a slew of safety concerns that cropped up in company trials, including memory lapses, suicidal thoughts, heart palpitations and birth defects.

In contrast, Arena’s weight loss drug, lorcaserin is much safer, but hasn’t shown to shed pounds as much as Vivus’ drug, Qnexa. Lorcaserin is the most advanced candidate in Arena Pharmaceuticals’ pipeline. It is a member of a new class of selective serotonin 2C receptor agonists. The serotonin 2C receptor is expressed in the brain, including the hypothalamus, an area involved in the control of appetite and metabolism. Stimulation of this receptor, the company said, is strongly associated with feeding behavior and satiety. The FDA is expected to act on Arena’s application to begin marketing lorcaserin by October 22.


Shares of Orexigen Therapeutics (Nasdaq: OREX), whose diet drug Contrave is also up for approval, plummeted 12.6 percent to $4.37. Many industry experts believe that while Contrave is safer than Qnexa, its safety profile may not be as strong as Arena’s lorcaserin. Contrave combines the antidepressant Wellbutrin with a sustained-release version of an opioid blocker used to treat alcohol, drug, and other addictions. The company said a late-stage trial of Contrave in patients with type 2 diabetes showed that after 56 weeks of treatment, overweight or obese patients with the disease lost significantly more weight and achieved greater improvement in glycemic control than those treated with placebo. Orexigen is up for review in January.

ARNA was recently upgraded to Overweight from Neutral by JP Morgan, with a price objective increasing to $6 from $5. Arena Pharmaceuticals, was also downgraded to Market Underperform from Market Perform by Rodman & Renshaw on Friday morning. The R&R analyst put a paltry $1 price target on the stock, citing efficacy and safety concerns that could present “regulatory challenges” for the firm’s Lorcaserin diet drug.

The market research firm Datamonitor referred to obesity in a 2009 report as the “$11 billion market that never was” as it forecast drug sales in the category to reach just $560 million in 2018, far less that the $12.2 billion market opportunity it says is there. The problem, says Datamonitor, is that “current approaches just aren’t good enough to capitalize on this opportunity.”
