Talecris Biotherapeutics Enrolls Patients in Clinical Trial Evaluating Two Doses of PROLASTIN®-C
Date:12/9/2010

RESEARCH TRIANGLE PARK, N.C., Dec. 9, 2010 /PRNewswire-FirstCall/ -- Talecris Biotherapeutics, Inc. (Nasdaq: TLCR) announced today the initiation of a clinical trial evaluating the safety and the pharmacokinetic profile of two doses of PROLASTIN®-C (Alpha(1)-Proteinase Inhibitor [Human]) (A1PI), a therapy indicated for chronic augmentation and maintenance in adults with emphysema due to alpha(1)-antitrypsin (AAT) deficiency. AAT deficiency is a rare, genetic disorder in which low levels of the alpha(1) protein circulating in the lungs can increase an individual's risk of developing emphysema.

This study will investigate the safety and pharmacokinetic profile of a higher dose, 120 mg/kg weekly, of PROLASTIN-C versus the licensed dose of 60 mg/kg weekly.  Subjects in the study will be randomized to receive either the 120 mg/kg dose or the 60 mg/kg dose for 8 weeks.  Subjects will then cross over to the alternate dose for an additional 8 weeks.  The study will be conducted at five sites across the United States.  Further information regarding this ongoing study can be found on ClinicalTrials.gov (study identifier NCT01213043).

"As part of our ongoing commitment to the Alpha-1 community, Talecris is exploring the possible use of higher doses of PROLASTIN-C in patients with emphysema due to AAT deficiency," said Kim Hanna, Vice President of Clinical Development at Talecris. "Data from this study may set the foundation for future research to further evaluate higher doses."

About PROLASTIN®-C

PROLASTIN-C is indicated for chronic augmentation and maintenance in adults with emphysema due to deficiency of alpha(1)-proteinase inhibitor (alpha1-antitrypsin deficiency).  AAT deficiency is a genetic condition in which low levels of the alpha1 protein can result in emphysema. The active protein in PROLASTIN-C increases or "augments" protein levels in AAT deficient patients.   In the U.S. and Canada, PROLASTIN-C has replaced PROLASTIN, the leading augmentation therapy in North America for more than 20 years.  

Important Safety Information for PROLASTIN-C

The effect of augmentation therapy with any alpha(1)-proteinase inhibitor on pulmonary exacerbations and on the progression of emphysema in alpha(1)-antitrypsin deficiency has not been demonstrated in randomized, controlled clinical trials.

PROLASTIN-C may contain trace amounts of IgA.  Patients with known antibodies to IgA, which can be present in patients with selective or severe IgA deficiency, have a greater risk of developing potentially severe hypersensitivity and anaphylactic reactions.  PROLASTIN-C is contraindicated in patients with antibodies against IgA.

The most common drug related adverse reactions during clinical trials in greater than or equal to 1% of subjects were chills, malaise, headache, rash, hot flush, and pruritus.  The most serious adverse reaction observed during the clinical studies with PROLASTIN-C was an abdominal and extremity rash in one subject.

PROLASTIN-C is made from human plasma. Products made from human plasma may carry a risk of transmitting infectious agents, e.g., viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

About Alpha(1)-Antitrypsin Deficiency

Alpha(1)-antitrypsin deficiency, also known as AAT deficiency or Alpha-1, is an inherited disorder that causes significant reduction in the naturally occurring protein alpha(1)-proteinase inhibitor. It is most common in the Caucasian population of northern Europe and North America. AAT deficiency is also the most common cause of genetic liver disease in children, and genetic emphysema (shortness of breath) in adults. Individuals suffering from AAT deficiency often develop severe chronic obstructive pulmonary disease (COPD) causing disability and premature death. AAT deficiency is estimated to affect 200,000 people in North America and Europe combined, although greater than 90% remain undiagnosed.
