A Study to Investigate the Safety, Tolerability, Pharmacokinetics and Efficacy of BC 007 in Healthy Subjects

Part A

Primary objective is:

• To assess safety and tolerability of BC 007 after a single ascending intravenous (i.v.) bolus + infusion in healthy, young and elderly subjects.

Secondary objectives are:

• To determine the pharmacokinetic plasma and urine profiles of BC 007 in healthy, young and elderly subjects.

Part B

Primary objective is:

• To assess the neutralizing potency of BC 007 against GPCR autoantibodies alpha -1 adrenergic receptor, beta-1 adrenergic receptor, beta-2 adrenergic receptor or endothelin-A-receptor following ascending i.v. bolus + infusion.

Secondary objectives are:

• To assess safety and tolerability of BC 007 after a single ascending i.v. bolus + infusion in GPCR AAB (α(1)-adrenergic receptor AAB, ß(1)-adrenergic receptor AAB, ß(2)-adrenergic receptor AAB or endothelin-A-receptor AAB) positive healthy elderly subjects.
• To determine the pharmacokinetic plasma and urine profiles of BC 007 in GPCR AAB (α(1)-adrenergic receptor AAB, ß(1)-adrenergic receptor AAB, ß(2)-adrenergic receptor AAB or endothelin-A-receptor AAB) positive healthy elderly subjects.

Part C

Primary Objective

• To assess the neutralizing potency of BC 007 against GPCR autoantibodies alpha-1 adrenergic receptor (α(1)-AR AAB), beta-1 adrenergic receptor (ß(1)-AR AAB), beta-2 adrenergic receptor (ß(2)-AR AAB) or endothelin-A-receptor (ETA AAB) following ascending i.v. bolus + infusion.

Secondary Objectives

• To assess safety and tolerability of BC 007 after a single ascending i.v. bolus + infusion in GPCR AAB (α(1)-AR AAB, ß(1)-AR AAB, ß(2)-AR AAB or ETA AAB) positive healthy elderly subjects.
• To determine the pharmacokinetic plasma and urine profiles of BC 007 in GPCR AAB (α(1)-AR AAB, ß(1)-AR AAB, ß(2)-AR AAB or ETA AAB) positive healthy elderly subjects.

Explorative Objective

• To investigate the pharmacokinetic plasma and urine profiles of BC 007 metabolites in GPCR AAB (α(1)-AR AAB, ß(1)-AR AAB, ß(2)-AR AAB or ETA AAB) positive healthy elderly subjects

Inclusion criteria

(main):

• The subject is a healthy, male, non-smoker or slight/occasional smoker (less than or equal to 10 cigarettes per day), 18 to 45 years of age (Cohorts 1 to 3, Part A).
• The subject is a healthy, male or female, non-smoker or slight/occasional smoker (less than or equal to10 cigarettes per day), 55 to 70 years of age (Cohort 4 [only in Part A] and Part B).
• Female subjects are postmenopausal (verified by an appropriate serum FSH level and amenorrhea for at least one year).
• The subject has a body mass index (BMI) range of 18.5 to 29.9 kg/m2 inclusive, (healthy young males as well as elderly subjects) and weighs at least 50 kg and < 100 kg.
• The subject is positive for either one or the combination of GPCR α(1)- adrenergic receptor AAB, ß(1)-adrenergic receptor AAB, ß(2)-adrenergic receptor AAB and endothelin-A-receptor AAB (Part B only) at (pre-) screening prior to enrolment.
• The subject is negative for GPCR α(1)-adrenergic receptor AAB, ß(1)-adrenergic receptor AAB, ß(2)-adrenergic receptor AAB and endothelin-A-receptor AAB at (pre-)screening prior to enrolment (Part A only).
• Coagulation variables, uric acid, ALT, AST, alkaline phosphatase (ALP), GGT, bilirubin and creatinine must be within the normal laboratory reference ranges at screening.
• Thyroid-stimulating hormone (TSH) must be within the normal laboratory reference range at screening.

Exclusion criteria

(main):

• Any history or evidence of any clinically significant cardiovascular, gastrointestinal, endocrinologic, hematologic, hepatic, immunologic, metabolic (specifically gout), urologic, pulmonary, neurologic, dermatologic, psychiatric, renal, and/or other major disease or malignancy, as judged by the Investigator.
• Any history or current intake of beta blockers.
• Any history of allergic reactions.
