Florida Biologix® Announces Manufacturing Agreement with Altor BioScience

June 28, 2011 Alachua, FL. Altor BioScience and Florida Biologix team up to move an important interleukin-15 (IL-15)-based immunotherapeutic, ALT-803, to the clinic as a novel cancer therapy. ALT-803, a proprietary IL-15 super agonist/IL-15Rα-Fc fusion complex, has demonstrated impressive anti-tumor activities in various pre-clinical cancer models and could potentially make a life-changing difference for patients with solid and hematological tumors. Florida Biologix will manufacture ALT-803 for clinical studies planned for early 2012.

Florida Biologix will conduct an engineering run, cGMP manufacturing including mammalian cell culture at 400 Liter scale and chromatographic purification, formulation and aseptic fill of the cytokine complex. Initially, the product will be evaluated in a Phase I/IIa clinical trial against superficial bladder cancer at M.D. Anderson Cancer Institute in Orlando with the support of a Florida Department of Health - James & Esther King Biomedical Research grant awarded to Dr. Charles J. Rosser, M.D. Altor also plans to initiate other cancer trials using Florida Biologix-manufactured ALT-803.

Altor BioScience CEO, Dr. Hing Wong, explained, “We chose to work with an experienced biologics manufacturing team that we believe will deliver a high-quality product within our budget and our aggressive timeline. Altor has successfully worked with Florida Biologix in the past on several fill and finish projects. We are thrilled to be able to expand this relationship with them to move this promising anti-cancer drug into clinical development.”

Florida Biologix Director, Dr. Richard Snyder, stated, “We are appreciative of Altor’s confidence in Florida Biologix’ capability and are excited to be a member of the team to develop this potentially life-changing therapy for cancer patients.”
