Outlook Therapeutics Refiling BLA in September

Share

Outlook Therapeutics has withdrawn a BLA submitted in March for Lytenava (bevacizumab-vikg) for treating wet age-related macular degeneration (wet AMD). FDA has requested additional information before it will accept the filing, the company says, adding that it plans to resubmit the BLA in September. “If approved, Lytenava could replace the current practice of using unapproved repackaged IV [intravenous] bevacizumab sourced from compounding pharmacies for the treatment of wet AMD,” the company says. 

  

The submission was based on data from the company’s NORSE ONE and TWO and Phase 3 pivotal trials. It also includes integrated safety data from the NORSE registration clinical program. “We observed a total of one ocular inflammation adverse event (iritis) reported from our three completed NORSE clinical studies,” the company says. 

  

Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds with high affinity to all isoforms of human vascular endothelial growth factor (VEGF) and neutralizes VEGF’s biologic activity through a steric blocking of the binding of VEGF to certain receptors, according to the company. It was first approved in 2004 as Genentech’s Avastin as a first-line treatment for patients with metastatic colorectal cancer.  

  

Outlook Therapeutics has entered into a partnership with FujiFilm Diosynth Biotechnologies for drug substance manufacturing, and with Aji Biopharma Services for finished drug product manufacturing.
