Pfenex NDA Approved for Forteo Copy
FDA has approved a Pfenex Inc. 505(b)(2) NDA for PF708 (teriparatide injection) that referenced Eli Lilly’s Forteo, indicated for treating osteoporosis in certain patients at high risk for fracture. According to Pfenex, Forteo had $1.6 billion in global sales last year.
Pfenex says it has asked FDA to designate PF708 as therapeutically equivalent (A-rated) to Forteo, which would permit it to be automatically substituted for Forteo in many states. To support this, Pfenex is conducting a comparative human factors study between PF708 and Forteo as requested by the agency. Pfenex expects to submit a final study report later this month and believes that this completes the information package to evaluate the drug’s therapeutic equivalence.
