A Kinder and Gentler FDA?

In an attempt to assuage the jitters and financial concerns of investors who own stock in pharmaceutical, biotechnology and medical device companies, the US Food and Drug Administration announced yesterday that it will be change the format of the letter received by companies whose products are not ready for approval.

In the old days (at least until yesterday), when the agency determined that drugs were not suitable for sale, it would send companies a so-called non-approval letter. This letter was designed to inform drug and device makers that their products had issues that needed to be resolved before the agency will approve them. Apparently, (at least according to drug and device manufacturers), receipt of non-approval letters by companies signaled to investors that the product in question would never, under any circumstances, be approved by FDA. This urban legend was born because most companies that receive non-approvable letters decide against investing more time and money into products that FDA has deemed “unapprovable” i.e. there isn’t enough of a financial inducement or upside to continue further development.

Now, when new products are not up to snuff, companies will receive something called a “complete response letter.” According to the agency, the new letters will describe what is missing from a new drug or device application and, when, appropriate, offer advice on how to fix or address the problem(s). However, because contents of FDA letters are not released to the public, investors may now be less informed about the prospects of a new drug than in the past when the agency was able to send “approvable” or “non-approval” letters to companies.  “While this new plan may provide more detailed information to a company regarding issues that need to be addressed, investors will likely be kept in the dark on the true status of a drug’s approvability” said a pharmaceutical analyst after learning about the format changes. He went on to say “Investors will no longer know whether a drug is truly dead in the eyes of FDA.”

In my opinion, this is another example of FDA cow towing to the whims and wishes of industry. Whether you call it, a “non-approvable” or “complete response letter”, it still means the same thing—the drug or device is not ready for prime time! I don’t think that the change in semantics will do anything to assuage concerns of jittery investors. What it WILL do is force investors to rely solely on the honesty of the management teams that receives these letters—Oy!

I think that FDA ought to stick to the business of evaluating the safety and efficacy of drugs and be less concerned with the political and economic needs of the drug and device industries. Finally, it would be prudent for FDA to allow appropriately trained professionals to provide psychotherapy to all of the frightened and jittery investors out there!!

Until next time…

Wyeth Regulatory Woes Continue

The regulatory problems at Wyeth continue. The US Food and Drug Agency announced that it issued an approvable letter for Tygacil (Wyeth’s tetracycline-like antibiotic) to treat community acquired pneumonia (CAP). Apparently, FDA regulators want more data on the effectiveness and safety of Tygacil in severe cases of CAP and additional information on possible liver toxicity.

Tygacil, an intravenously administered antibiotic, won FDA approval in 2005 to treat adults with complicated intra-abdominal infections and complicated skin and skin-structure infections. Tygacil had about $138 million in sales last year; falling far short of the projected $500-$800 million in annual sales that it was expected to yield when it was first brought to market. If Wyeth gains approval for CAP, expect Tygacil sales to soar.

In other regulatory news, FDA granted Wyeth “fast-track approval” for a new version of its market-leading pediatric pneumococcal vaccine called Prevnar. The new 13-valent formulation will provide protection against 13 different pneumococcal serotypes. The older version only provided protection against 7 serotypes. Wyeth hopes to complete its filing for pediatric use of the new Prevnar vaccine in early 2009. Prevnar is Wyeth’s second-leading product with sales of about $2.5 billion in 2007.  

The new Prevnar vaccine will likely go head-to-head with GlaxoSmithKline’s new 10-valent pneumococcal vaccine  called SynflorixTm which is in late stage clinical development and is currently being reviewed for marketing approval in the EU. Unlike Wyeth’s vaccine, SynflorixTm  was found to be effective in protecting against otitis media (ear infections) caused by Haemophilus influenzae.

Until next time,

FDA Rejects Merck's New Cholesterol Medication

It seems like nothing is going right for Merck these days. On Monday, the US Food and Drug Administration (FDA) issued a “not approvable”–aka a rejection letter–for Merck’s new cholesterol drug called Cordaptive or MK-0524A. The highly-touted drug, which Merck executives hoped would replace Merck’s blockbuster cholesterol drug, Zocor (which lost patent protection a couple of years ago), can both lower LDL (bad) and raise HDL (good) cholesterol. Although experts believe that these properties should benefit people with high cholesterol, the results from recent clinical trials suggest that drugs that raise LDL and lower HDL cholesterol may have safety problems.

Cordaptive consists of an extended-release form of niacin (a B vitamin) and another agent that inhibits a niacin side effect called flushing — redness, burning and tingling of the face. Niacin has been used to control cholesterol for decades. Abbott Laboratories already sells an extended-release form of niacin called Niaspan.

Despite positive results from recent clinical trials and pending approval by the European Union, the agency rejected Merck’s NDA. Regulators also rejected Cordaptive as a brand name. It is likely that FDA is scrutinizing and proceeding cautiously with new cholesterol medications because of the recent flap over Zetia and Vytorin (which are co-marketed and sold by Merck and Schering Plough). As you may recall, both companies have been accused of trying to protect sales of the two drugs by delaying results of a study that showed Vytorin worked no better than Zocor, which is much cheaper.  Merck’s stock price dropped about 5% yesterday after the company announced that it received a not approvable letter from FDA.

Although MK-0524A may ultimately reach the US market, I wouldn’t count on it anytime soon. Merck has seriously tarnished its reputation with FDA because of the Vioxx, Vytorin and Singular controversies. The old adage, “You reap what you sow” is particularly apt in this instance. Look for more “asset reallocation” moves in Rahway.

Until next time…
