FDA Delays Approval of Ceftobiprole to treat MRSA

U.S. regulators have delayed a decision on approval of an antibiotic from Johnson & Johnson and Basilea saying they need further audits of clinical sites, the two companies said on Wednesday.

Ceftobiprole, a broad-based spectrum antibiotic targeted mainly against infections caused by methicillin-resistant Staphylococcus aureus (MRSA), is Basilea's lead product and the news hit the Swiss biotech shares, which plummeted 27 percent.

In a so-called complete response letter on the drug's approval application, for complicated skin and skin structure infections, the Food and Drug Administration (FDA) said it was unable to review the clinical data submitted with the NDA until issues of data integrity had been resolved. The FDA has asked J&J to conduct additional audit work of clinical investigator sites and to address specific questions related to site monitoring."

Ceftobiprole is approved in Canada and Switzerland and has been recommended for approval in the European Union. A new application in the United States is planned within a year.

Late last week, FDA rejected an NDA for another antibiotic, iclaprim, being developed by Arpida, another Swiss company. It has been a bad two weeks at FDA for approval of new antibiotics—drugs that we desperately need.

Until next time….

Happy Thanksgiving

 

Antibiotic Approval Update

Basilea Pharmaceutica Ltd announced yesterday that the U.S. Food and Drug Administration issued an Approvable Letter for ceftobiprole, a first-in-class anti-MRSA broad-spectrum cephalosporin, for the treatment of complicated skin and skin structure infections including diabetic foot infections. Results from two Phase III studies involving 1600 patients with complicated skin and skin structure and diabetic foot infections showed that ceftobriprole was as effective and safe as other cephalosporin antibiotics.

The Approvable Letter indicates that the ceftobiprole application is approvable, subject to completion and assessment of clinical study site inspections; assessment of clinical and microbiological data provided but not yet reviewed; and further characterization of patients with diabetic foot infections. Ceftobiprole is currently being reviewed by regulatory authorities in Canada, the European Union and in Switzerland. The antibiotic is being co-developed and marketed with Johnson and Johnson.

Until next time…

FDA Delays Another Decision on a New Antibiotic

Where have the folks at FDA been hiding for the past decade?  I thought that by now everybody had heard about multi-drug resistant bacteria and the need for new antibiotics. Why, I bet that even President Bush knows this –hmmmm– well, okay– but you get my point!

FDA announced today that it needs more data and time to evaluate Johnson and Johnson’s “new indication” NDA for its antibiotic Doribax (doripenem). The antibiotic is already approved to treat urinary tract and intra-abdominal infections. The company is seeking approval to expand treatment to cover nosocomial or ‘hospital-acquired’ pneumonia as well as ventilator-associated pneumonia.

The new application was submitted in June 2007 but the FDA’s request for new data means that the review period has been extended by at least three months. Doribax is licensed from Japanese drug maker Shionogi and is currently undergoing regulatory review in Europe, Canada and in other countries.

This delay comes less than a month after the agency cancelled a meeting of its anti-infective drugs advisory committee which was scheduled for February 28. At that meeting, the agency was scheduled to review another J&J antibiotic ceftobiprole, which is being co-developed with Switzerland’s Basilea Pharmaceutica. No reason was given by the agency for cancellation of the ceftobiprole
meeting which is being evaluated as a treatment of complicated skin and skin structure infections, including diabetic foot infections.

I am not sure why FDA can’t make up its mind about the approvability of new antibiotics. They certainly had little difficulty approving Vioxx, Zyprexa and Avandia.  Maybe FDA ought to hire some more microbiologists? 

Until next time….

FDA Delays Decisions on Two New Antibiotics to Treat MRSA

The US Food and Drug Administration said Monday it still had several "outstanding issues" with televancin an antibiotic being developed by Theravance Inc and Astellas Pharma of Tokyo. to treat skin infections.

The agency had canceled an advisory committee meeting scheduled for Wednesday that was set to evaluate the drug, televancin.

In a statement, the agency said that the meeting was being canceled to "allow time for the FDA to review and resolve several outstanding issues." The FDA said it would schedule an advisory committee meeting in the future, if needed.

Televancin is a once-daily injectable antibiotic that would be used to treat skin infections, including those caused by resistant bacteria like methicillin-resistant Staphylococcus aureus (MRSA). In October the FDA issued a so-called approvable letter for televancin, suggesting it needed a re-analysis of clinical data and the resolution of manufacturing issues at a third-party manufacturer that was not specifically related to televancin. The FDA said it continues to review televancin's application but didn't give a timetable for completion of the review.

Earlier this month the FDA canceled a Feb. 28 meeting for another antibiotic, ceftobiprole that would also be used to treat skin infections. That drug is being developed by a unit of Johnson and Johnson Co. and Switzerland-based Basilea Pharmaceutica Ltd. The FDA is expected to make a decision on whether to approve ceftobriprole sometime next month.
