GlaxoSmithKline Suffers Another Regulatory Setback

US Food and Drug Administration regulators announced on Friday that it will take three months longer than expected to decide whether Entereg, a treatment for post-operative ileus being co-developed by GlaxoSmithKline, will receive marketing approval. The drug was originally supposed to be reviewed for an up-or-down decision on Feb. 10.

Entereg is being co-developed with Pennsylvania-based Adolor Corporation. Post-operative ileus affects patients after bowel surgery. Symptoms include constipation and other gastrointestinal dysfunction.

An FDA advisory panel recommended approval in January but said Adolor needed to come up with a better plan to manage long term use of the drug. FDA regulators are concerned about safety data showing that long term use of Entereg can have adverse cardiovascular effects.

Adolor has submitted a new risk-management plan to the FDA, which will take the extra three months to review it.  GlaxoSmithKline will split the revenue from any U.S. sales of Entereg with Adolor and is responsible for commercialization of the drug outside the country.

Until next time…

More Bad News for GSK: Cervarix Launch in US is Unlikely until 2009

Last December, the US Food and Drug Administration (FDA) asked GlaxoSmithKline for additional information related to its cervical cancer vaccine Cervarix. The company has yet to reply to unspecified queries in the FDA's "complete response letter" that it received last December.

Many analysts believe Cervarix is now unlikely to be launched until 2009 at the earliest. GSK won European regulatory approval last July for the vaccine and had originally anticipated a US launch by the start of this year. However, FDA requested clarification after GSK's submission last April based on interim clinical data that the submitted from its most comprehensive five-year clinical trial for the vaccine. Financial analysts believe that FDA concerns may center on GSK's proprietary AS04 adjuvant that is used  in Cervarix to improve the effectiveness of the vaccine.

The delay has been a serious blow to GSK’s efforts to generate fresh product sales and catch up with Gardasil, the rival HPV vaccine developed by Merck & Co, which is available in the US and Europe.

I wonder whether the delay at FDA is really based on legitimate regulatory and scientific concerns. As you may recall, Merck launched a flat-out, take-no-prisoners lobbying campaign to get State and Federal legislators to mandate that all girls 10-21 years old be vaccinated with Gardasil. While Merck abruptly abandoned its lobbying efforts last fall after it came under fire from various legislative and regulatory sources, I can’t help but wonder whether Merck achieved its intended objectives anyway—to keep Cervarix out of the US market as long as possible so that Merck can capture a majority share of the lucrative American cervical cancer market.

Until next time….

Another Wyeth Drug Is Delayed!

Wyeth and its development partner, Tarrytown NY-based Progenics Pharmaceuticals Inc, said on Thursday that U.S. regulators have delayed a review of their experimental drug to treat opioid-induced constipation in order to further review certain safety data.

The U.S. Food and Drug Administration asked for the results of a recently completed study of the drug, methylnaltrexone, on QT prolongation, a disorder of the heart's electrical system. The companies said the study submitted to the FDA examined the effect of intravenous methylnaltrexone, which is being developed for post-operative ileus, a dysfunction of the gastrointestinal tract following surgery.

Both companies hope that FDA will review the application by the end of April, three months later than expected. I suspect that the old adage “If at first you don’t succeed, try, try, and try again” may be the new mantra at Wyeth these days!

Until next time….
