Another New Antibiotic Bites the Dust (for now)
Pfizer announced today that it would withdraw marketing application being considered at FDA and the European Medicines Agency (EMEA) for Dalbavancin an antibiotic it was developing for complicated skin infections caused by bacteria including methicillin-resistant Staphylococcus aureus (MRSA).
Pfizer acquired Dalbavancin after it purchased California-based Vicuron Pharmaceuticals for $1.9 billion in 2005. At that time, Vicuron had filed an NDA with FDA and had expected approval for the novel antibiotic. Instead, after acquiring Vicuron, Pfizer received an approvable letter from FDA that requested additional studies before the agency would approve the drug. Based on the agency’s comments, Pfizer decided to withdraw the original US and European applications filed by Vicuron and conduct addition Phase III clinical trials for the complicated skin and soft tissue infection and pediatric indications. I suspect that results from these trials will determine whether Pfizer files new applications with FDA and EMEA for Dalbavancin.
For those of you who may not know, Vicuron Pharmaceuticals was formerly called Versicor, a company founded by Eric Gordon, Mickey Gorman and others. In 1996, I was recruited to interview for a Vice President of Biology position at the company. At that time, Versicor had about 15 employees — Eric was CEO and Mickey was a consultant. Although Eric, Mickey and I became fast friends, I didn’t get the job (they never hired anybody for the position).
Both Eric and Mickey left Versicor a couple of years later. Eric went on to start Sunesis, a very successful Bay area oncology company and Mickey retired to his home in Key West, FL. From time to time, I would run into Eric at BIO meetings and Mickey and I would meet up at my all time favorite Vietnamese restaurant (Hy Vong) in Little Havana in Miami, FL. Eric has since retired after 30 years in the pharma/biotech biz and Mickey unfortunately passed away from cancer in the early 2000s.
After meeting Eric and Mickey, I knew that Versicor would be a success one day—the $1.9 billion that Pfizer paid for Vicuron tends to validate that notion. While I didn’t benefit financially from Versicor, I was lucky and fortunate to meet two, really smart, fascinating and genuine individuals who helped me to establish my credibility in the biopharmaceutical industry. As the saying goes “Money isn’t everything!”

Good Luck and Good Job Hunting!!!!!
