A Randomized, Placebo-Controlled, Double-Blind, Multicenter Phase III/IV Study to compare the Efficacy and Safety of 60 mg/kg body weight of Zemaira weekly i.v. administration with Placebo weekly i.v. administration in Chronic Augmentation and Maintenance Therapy in Subjects with Emphysema due to Alpha1-Proteinase Inhibitor Deficiency
Investigator: Michael Campos
Institutional Protocol #: 20071125
National Clinical Trials Identifier: NCT00261833
Funding Agency/Sponsor: CSL Behring
Division: Pulmonary and Critical Care
Therapeutic Area: Other
Phase: Phase IV
Enrolling Sites: University of Miami Medical Group
Enrolling Since: 7/30/2013
This is a randomized, placebo-controlled, double-blind, multicenter phase III/IV study to
compare the efficacy and safety of Zemaira® with placebo in subjects with emphysema due to
alpha1-proteinase inhibitor deficiency. The effect of Zemaira® on the progression of
emphysema will be assessed by the decline of lung density, measured by computed tomography
- 18 to 65 years of age and willing to sign informed consent.
- Males and non-pregnant, non-lactating females whose screening pregnancy test is
negative and who are using contraceptives methods deemed reliable by the investigator.
- Diagnosis of alpha1-proteinase inhibitor (A1-PI) deficiency (serum A1-PI levels < 11
μM or < 80 mg/dL). This includes newly diagnosed subjects, previously untreated
subjects, currently treated subjects, and subjects currently not on treatment therapy
but on treatment in the past.
- Subjects with emphysema and forced expiratory volume in 1 second (FEV1) ≥ 35% and ≤
- No signs of chronic or acute Hepatitis A, Hepatitis B, Hepatitis C or HIV infection
(negative serologies for HIV and viral hepatitis). In case of positive serologies for
viral hepatitis, vaccination status or negative IgM should be available.
- Any relevant chronic diseases or history of relevant diseases (e.g., severe renal
insufficiency) except respiratory or liver disease secondary to alpha1-proteinase
inhibitor deficiency. Subjects with well-controlled, chronic diseases may be included
after consultation with the treating physician and the sponsor.
- Current evidence of alcohol abuse or history of abuse of illegal and/or legally
prescribed drugs such as barbiturates, benzodiazepines, amphetamines, cocaine,
opioids, and cannabinoids.
- History of allergy, anaphylactic reaction, or severe systemic response to human plasma
derived products, or known mannitol hypersensitivity, or history of prior adverse
reaction to mannitol.
- History of transfusion reactions.
- Selective IgA deficiency.
- Acute illness within one week prior to the first administration of the investigational
medicinal product (IMP). Start of treatment after recovery is possible.
- Current tobacco smoker (smoking has to be ceased at least 6 months prior study
inclusion). Subjects with a positive cotinine test due to nicotine replacement therapy
(e.g. patches, chewing gum) or snuff are eligible.
- Conditions or behaviors that interfere with attending scheduled study visits in the
opinion of the investigator.
- History of non-compliance.
- Administration of any other experimental new drug or participation in an investigation
of a marketed product within one month prior to the screening visit date.
- Inability to perform necessary study procedures.
- Lung transplantation, lung volume reduction surgery or lobectomy or being on a waiting
list for any such surgeries.
