BlueWillow Biologics®, a clinical-stage biopharmaceutical company, announced this week that the U.S. Food and Drug Administration (FDA) has cleared its investigational new drug (IND) application for BW-1010, the company’s next-generation anthrax vaccine candidate. The Phase 1 clinical study is expected to begin enrollment this year and is being funded by the National Institute of Allergy and Infectious Diseases (NIAID), an institute within the National Institutes of Health (NIH).


Development of an intranasal anthrax vaccine is ongoing through BlueWillow’s partnership with Porton Biopharma Limited (PBL) under contract #HHSN272201600045C from NIAID for the development of a next-generation NanoVax® anthrax vaccine. The contract could be worth up to $24 million over its eight-year term if all options are exercised. The vaccine combines BlueWillow’s novel intranasal NanoVax system with recombinant protective antigen (rPA) for anthrax from PBL. The NanoVax platform employs a proprietary oil-in-water nanoemulsion adjuvant that elicits both systemic and mucosal immunity, uniquely enabling protection against challenging respiratory infections such as anthrax.

Anthrax is listed as a Category A priority pathogen by NIAID, indicating the biological agent poses the highest possible risk to national security and public health. When introduced to the body through inhalation, ingestion or cuts in the skin, anthrax-causing bacteria can cause severe illness and death. The disease poses a massive threat in situations such as bioterrorism. To protect the nation against the potential risk of an anthrax attack, the U.S. Department of Health and Human Services (HHS) currently stores tens of millions of doses of injectable anthrax vaccine in the U.S. Strategic National Stockpile, the nation’s largest supply of potentially life-saving medical products for emergency use. The currently licensed injectable vaccine requires three immunizations in addition to antimicrobial therapy as a medical countermeasure following potential anthrax exposure. Evidence indicates the current vaccine may cause acute side effects, as well as the risk of potential fetal harm if administered to pregnant women.

“The BlueWillow/PBL anthrax vaccine has the potential to provide significant advantages over the current injectable vaccine,” said BlueWillow CEO Dave Peralta. “Animal studies have demonstrated BW-1010 is safe and elicits protection against anthrax after just one or two vaccinations. In addition, informal stability studies have shown that our vaccine has a shelf life of over five years, compared to three years for the current injectable vaccine. The improved stability of BW-1010 would allow for longer-term storage, potentially saving the U.S. government over $100 million annually.”
