Optimer Pharmaceuticals spokeswoman Christina Donaghy was killed in a car crash Sunday in Cardiff-by-the-Sea, CA, a suburban coastal community about 25 miles north of San Diego, according to a report today in The San Diego Union-Tribune. Donaghy, 43, was in the back seat of a 1974 Porche Targa when the driver lost control on Manchester Avenue and collided with a Chevy S-10 pickup. A man believed to be the driver was seriously injured and another man in the Porche also was killed. Two people in the pickup also were injured. Optimer is awaiting an FDA ruling on its new drug application for fidaxomicin, an antibiotic for treating C. difficile infections.
