FDA acknowledges transfer to Caelum Biosciences, a Fortress Biotech Company

New York, NY – April 5, 2017 – Fortress Biotech, Inc. (NASDAQ: FBIO) (“Fortress”), a biopharmaceutical company dedicated to acquiring, developing and commercializing novel pharmaceutical and biotechnology products, today announced that the U.S. Department of Health & Human Services has confirmed the transfer of two U.S. Food and Drug Administration (FDA) Orphan Drug Designations for CAEL-101 (also known as 11-1F4)  from Columbia University (“Columbia”) to Fortress’ subsidiary, Caelum Biosciences, Inc. (“Caelum”). The two Orphan Drug Designations include the use of CAEL-101 as a therapeutic agent for patients with AL amyloidosis, and the use of CAEL-101 as a radio-imaging agent in amyloidosis. Caelum in-licensed CAEL-101 from Columbia in January 2017.

CAEL‐101 is a fibril‐reactive monoclonal antibody (mAb) currently being evaluated in a Phase 1b study for the treatment of AL amyloidosis, a rare systemic disorder caused by an abnormality of plasma cells in the bone marrow. Misfolded amyloid proteins produced by plasma cells cause buildup in and around tissues, nerves and organs, gradually affecting their function. This can cause progressive and widespread organ damage, and high mortality rates.

Dr. Lindsay A. Rosenwald, Fortress Biotech’s Chairman, President and Chief Executive Officer, said, “The transfer of these two Orphan Drug Designations is significant for Caelum, as they will provide additional market exclusivity and financial benefits that will enable Caelum to advance CAEL-101 as a potential improved treatment option to AL amyloidosis patients in need. Preliminary data for CAEL-101 has demonstrated biomarker activity in a Phase 1a/1b study that may indicate the therapy’s ability to safely promote amyloid elimination and the subsequent improvement of organ function. We look forward to reporting full data from the Phase 1a/1b study later this year, and plan to initiate a Phase 2 study in 2018.”

FDA Orphan Drug Designation is granted to investigational therapies that address rare medical diseases or conditions that affect fewer than 200,000 people in the U.S. Orphan Drug status provides benefits to drug developers including assistance in the drug development process, tax credits for clinical costs, exemptions from certain FDA fees and seven years of marketing exclusivity.

Caelum’s lead asset, CAEL-101 (11-14F), is a novel antibody in Phase 1b clinical trials for the treatment of patients with amyloid light chain (“AL”) amyloidosis, a rare systemic disorder that results in the buildup of misfolded amyloid proteins in and around tissues, nerves and organs, gradually affecting their function. Interim Phase 1a/1b data presented at the American Society of Hematology’s (ASH) 58th Annual Meeting in December 2016 support CAEL-101’s potential to be a safe and well-tolerated therapy that promotes amyloid resolution. CAEL-101 has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) as a therapeutic agent for patients with AL amyloidosis, and as a radio-imaging agent in amyloidosis.
