Collagenex Settles Periostat Litigation With URL/Mutual; Lawsuit Against FDA Continues

Agency’s determination that doxycycline hyclate 20 mg is an “antibiotic” and not entitled to Waxman/Hatch exclusivity, if not reversed by a court, would impact an extended-release version currently in Phase III, Collagenex says. URL/Mutual will market its own branded version of the drug under a settlement and licensing agreement.
