OBILTOXAXIMAB RECEIVES POSITIVE CHMP OPINION FOR THE TREATMENT OF INHALATION ANTHRAX
European Commission Decision Anticipated in November 2020

PARSIPPANY, NJ, OCTOBER 8, 2020Elusys Therapeutics, Inc. (Elusys) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has adopted a positive opinion recommending marketing authorization under exceptional circumstances for obiltoxaximab, the company’s monoclonal antibody (mAb) anthrax antitoxin for the treatment of inhalation anthrax. Obiltoxaximab is indicated in all age groups in combination with appropriate antibacterial drugs for the treatment of inhalational anthrax due to Bacillus anthracis; and for post-exposure prophylaxis of inhalational anthrax when alternative therapies are not available or not appropriate.

It is anticipated that the European Commission, which has the authority to grant marketing authorization for medicinal products in the European Union (EU), will issue a final decision on the marketing authorization for obiltoxaximab in November 2020. SFL Pharmaceuticals Deutschland GmbH (SFL Pharmaceuticals) filed the marketing authorization application (MAA) and will act as future marketing authorization holder (MAH) in the EU on behalf of Elusys, the originator of the product.
“This positive CHMP opinion reflects important progress toward our goal of making this important medical countermeasure available in the EU,” said Elizabeth Posillico, PhD, President and Chief Executive Officer of Elusys. “With obiltoxaximab already approved and commercially available in the United States and with the recent approval by Health Canada, we are looking forward to pursuing additional opportunities for product availability to protect public health in nations where the U.S. has bilateral relations.”
The CHMP opinion is based on data from studies funded by U.S. government agencies, including the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services, the National Institutes of Health (NIH), and the U.S. Department of Defense (DoD).
“Our thanks to our EU partner, SFL Pharmaceuticals, for their expert guidance and efforts throughout the EU filing and approval process,” added Dr. Posillico.
