Abstract titled: “A High Titer Anti-RSV Polyclonal Antibody (RI-002) Prevents Infection with Palivizumab Resistant RSV in Cotton Rats and Achieves Greater Neutralizing Anti-RSV Activity as Compared to Palivizumab”
RAMSEY, N.J., March 07, 2016 (GLOBE NEWSWIRE) -- ADMA Biologics, Inc. (NASDAQ:ADMA), a late-stage biopharmaceutical company that develops, manufactures, and intends to commercialize specialty plasma-based biologics for the treatment and prevention of certain infectious diseases, today announced its abstract titled “A High Titer Anti-RSV Polyclonal Antibody (RI-002) Prevents Infection with Palivizumab Resistant RSV in Cotton Rats and Achieves Greater Neutralizing Anti-RSV Activity as Compared to Palivizumab” was presented as a poster session at the 2016 American Academy of Allergy Asthma & Immunology (AAAAI), annual meeting, being held March 4-8, 2016 in Los Angeles, California.
ADMA presented the results of preclinical experiments done in collaboration with Baylor University College of Medicine related to RSV prevention and treatment. The effects of RI-002, an intravenously administered Human Immunoglobulin preparation containing a high titer anti-RSV polyclonal antibody, were compared to palivizumab, a monoclonal anti-RSV antibody currently approved to prevent RSV infections in premature infants, in cotton rats infected with a palivizumab-resistant strain of RSV.
The data demonstrate that while palivizumab and RI-002 were comparable in diminishing the viral load in the lungs of RSV infected cotton rats, only RI-002 was effective in preventing RSV infection when a palivizumab-resistant strain of RSV was administered. Serum neutralization titers achieved by palivizumab at the approved dose level of 15mg/kg were approximately 4-fold lower than those achieved by a dose of 1500mg/kg of RI-002. Since palivizumab at 15mg/kg has been shown to be effective in preventing RSV infection in cotton rats and also in preventing RSV infection in humans, ADMA believes that the results obtained with RI-002 in this animal model warrant additional studies of RI-002 in humans for confirmatory purposes.
“We are pleased to have the opportunity to share this data with the scientific community at AAAAI, and believe the results underscore the importance of conducting additional studies in humans to gain a better understanding on how these results could translate into more therapeutic options for immune compromised patients,” stated Adam Grossman, President and CEO of ADMA Biologics.

About ADMA Biologics, Inc.
ADMA is a late-stage biopharmaceutical company that develops, manufactures and intends to commercialize specialty plasma-based biologics for the treatment and prevention of Primary Immune Deficiency Disease (PIDD) and certain infectious diseases. ADMA's mission is to develop and commercialize plasma-derived, human immune globulins targeted to niche patient populations for the treatment and prevention of certain infectious diseases. The target patient populations include immune-compromised individuals who suffer from an underlying immune deficiency disease, or who may be immune-compromised for medical reasons. ADMA’s lead product candidate, RI-002, has completed a Phase III clinical trial in patients with PIDD and has met the primary endpoint, and a Biologics License Application (BLA) for RI-002 was accepted by the U.S. Food and Drug Administration (FDA) on September 18, 2015. The company has received U.S. Patent 9,107,906. For more information, please visit www.admabiologics.com.
ADMA's lead product candidate, RI-002, is a specialty plasma-derived, polyclonal, intravenous immune globulin (IGIV) derived from human plasma containing naturally occurring polyclonal antibodies (e.g., Streptococcus pneumoniae, H. influenza type B, cytomegalovirus (CMV), measles, tetanus, etc.) as well as standardized, high levels of antibodies to respiratory syncytial virus (RSV). ADMA is pursuing an indication for the use of this specialty IGIV product for treatment of patients diagnosed with PIDD. Polyclonal antibodies are the primary active component of IGIV products. Polyclonal antibodies are proteins that are used by the body's immune system to neutralize microbes, such as bacteria and viruses. Data review indicates that the polyclonal antibodies present in RI-002 support its ability to prevent infections in immune-compromised patients. ADMA’s analysis demonstrated that the Phase III trial met the primary endpoint with no serious bacterial infections (SBI) reported. These results more than meet the requirement specified by the FDA guidance of ≤ 1 SBI per patient-year.
About Primary Immune Deficiency Disease (PIDD)
PIDD is a class of inherited genetic disorders that causes an individual to have a deficient or absent immune system due to either a lack of necessary antibodies or a failure of these antibodies to function properly. PIDD patients are more vulnerable to infections and more likely to suffer complications from these infections. According to the World Health Organization, there are over 150 different presentations of PIDD. As patients suffering from PIDD lack a properly functioning immune system, they typically receive monthly, outpatient infusions of IGIV therapy. Without this exogenous antibody immune support, these patients would be susceptible to a wide variety of infectious diseases. PIDD has an estimated prevalence of 1:1,200 in the United States, or approximately 250,000 people.
