  Purpose

Berlin Cures develops BC 007 to treat patients suffering from diseases (chronic heart failure, pulmonary hypertension, chronic fatigue syndrome etc.) which are associated with functional autoantibodies (AAB) directed against G-protein coupled receptors (GPCR).

The first part of the study (part A) is designed to evaluate the safety and tolerability of ascending doses of BC 007. The study part is blinded and placebo controlled in order to better discriminate possible safety signals. The assessment of safety and tolerability in an elderly cohort is a bridge to dosing elderly GPCR AAB positive subjects in part B. The subjects in part A are confirmed to be GPCR AAB negative.

The objective of the second part of the study (part B) is to evaluate the efficacy of BC 007 in neutralizing AAB against GPCR shortly after dosing compared to baseline and to find the optimal dose for the neutralization of the AAB in all individuals. This dose shall be taken to progress into a Phase II/III trial with beta1-adrenergic receptor-AAB positive patients suffering from chronic heart failure.

Part A:

BC 007 at doses of 15, 50 and 150 mg or matching placebo administered as i.v. bolus + infusion of 20 min (Cohorts 1 to 4). The sentinel pair of each cohort will be dosed without bolus.

NaCl 0.9% (matching placebo) administered as i.v. bolus + infusion of 20 min (Part A: Cohorts 1 to 4).

Part B:

BC 007 at doses of 50 and 150 mg administered (Cohort 1) or a single dose < 50 mg or 150 mg (Cohort 2) as i.v. bolus + infusion of 20 min is administered to GPCR autoantibody positive subjects. The first subject in each dosing period of Cohort 1 will be dosed without bolus.

Part C:

BC007 administered at doses of 300 mg (Cohort 1), 450 mg (Cohort 2), 750 mg (Cohort 3), 1350 mg (Cohort 4) as i.v. bolus + infusion of 40 min to GPCR autoantibody positive subjects. The first three subjects in each dosing period of Cohort 1-4 will be dosed without bolus. In Cohort 5 BC007 dose of 1200 mg will be administered as a continuous infusion of 20 min.
