RAMSEY, N.J.--(EON: Enhanced Online News)--ADMA Biologics, Inc. (OTCQB:ADMA), a late-stage biopharmaceutical company that develops, manufactures, and intends to market specialty plasma-based biologics for the treatment and prevention of certain infectious diseases announced today that data from its previous Phase II trial, compassionate use experience and testing in the cotton rat RSV animal model was presented at the 2013 RSV Vaccines for the World Conference (RSVVW). The abstract is titled: “Polyclonal human IVIG with standardized high-levels of RSV neutralizing antibodies: A summary of animal and human studies.”
“While vaccines may offer protection to patients that have functional immune systems, vaccines are not typically given to immune-compromised patients. Polyclonal immune globulin products like ADMA’s IVIG may provide an effective alternative for patients who could benefit from passive immunity against foreign pathogens.”
The oral presentation was given during the session “RSV Protection Using Non-Vaccine Approaches.”
“The data presented at the 2013 RSVVW demonstrates the potential for offering a polyclonal immune globulin product with standardized, elevated levels of anti-RSV antibodies in immune-compromised patient populations,” stated James Mond, M.D., Ph.D., Chief Medical & Scientific Officer for ADMA Biologics. “While vaccines may offer protection to patients that have functional immune systems, vaccines are not typically given to immune-compromised patients. Polyclonal immune globulin products like ADMA’s IVIG may provide an effective alternative for patients who could benefit from passive immunity against foreign pathogens.”
Topics from the RSVVW presentation included:
- Review of RSV mediated disease in immune-compromised hosts
- Description of ADMA IVIG product
Data from 3 studies
- Cotton rat RSV infection model, the accepted surrogate for human RSV mediated disease
- Phase II dose finding study in immune-compromised patients
- Compassionate human use data
The cotton rat model demonstrated:
- Infusion of ADMA IVIG eliminates 99% of viral load in nasal and lung tissue
- Highly significant increases in serum RSV neutralizing titers
The Phase II trial demonstrated:
- 86% of subjects with confirmed RSV infection who received high-dose regimen ADMA IVIG had a ≥4-fold rise in RSV neutralization titers (day 18, mean 9.2 fold)
- The drug was well tolerated in all study subjects and there were no serious adverse events attributable to the drug product
The compassionate use experience demonstrated:
- Majority of seriously ill patients had favorable outcomes when treated early (within 8.6 days of RSV diagnosis) (11/15 or 73% of RSV pulmonary infected patients survived)
- All patients tested who had not received prior administration of palivizumab had >4 fold rise in RSV neutralizing titers (day 8-18)
- The drug was well tolerated in all subjects and there were no serious adverse events attributable to the drug product
About ADMA Biologics, Inc.
ADMA is a late-stage biopharmaceutical company that develops, manufactures, and intends to market specialty plasma-based biologics for the treatment and prevention of 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 also operates ADMA Bio Centers, an FDA-licensed and GHA-certified source plasma collection facility located in Norcross, Georgia, which provides ADMA with a portion of its blood plasma for the manufacture of RI-002.

About ADMA’s lead product candidate RI-002
ADMA’s lead product candidate, RI-002 is a specialty plasma-derived, polyclonal, Intravenous Immune Globulin, or IGIV, derived from human plasma containing naturally occurring polyclonal antibodies (eg. streptococcus pneumoniae, H. influenza type B, CMV, measles, tetanus etc.) as well as high levels of antibodies targeted to respiratory syncytial virus, or RSV. ADMA is pursuing an indication for the use of this specialty IGIV product for treatment of patients diagnosed with primary immune deficiency diseases, or PIDD. Polyclonal antibodies are the primary component of IGIV products. Polyclonal antibodies are proteins produced by B-cells that are used by the body’s immune system to neutralize microbes such as bacteria and viruses. The polyclonal antibodies that are present in RI-002 are expected to prevent infections in immune-compromised patients. The product candidate is currently being evaluated in a Phase III trial in the United States.
