Clinical Trial Summary

The purpose of this study was to assess the safety and tolerability of multiple doses of a human monoclonal antibody (BAY1093884) given under the skin in subjects with hemophilia A or B. This antibody was intended to protect from bleeds by inhibiting a substance (Tissue Factor Pathway Inhibitor, TFPI) that reduces the ability of the body to form blood clots.


Description:

The primary objective of the study was to assess the safety and tolerability of multiple subcutaneous injections of BAY1093884 (anti-TFPI monoclonal antibody, immunoglobulin G2, IgG2) in patients with hemophilia A or B with or without inhibitors.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With Drug-related Treatment-emergent Adverse Events An adverse event (AE) was any untoward medical occurrence (i.e., any unfavorable and unintended sign [including abnormal laboratory findings], symptom or disease) in a participant in the study. Any bleeding event occurring during the study was not documented as an AE because this event was planned to be captured in the assessment of efficacy. AEs occurring after the first administration of study drug and up to and including 30 days after the last administration of study drug were defined as treatment-emergent AEs (TEAEs). Drug-related TEAEs were TEAEs that had "reasonable causal relationship" to the study treatment decided by the investigators. After the first administration of study drug and up to and including 30 days after the last administration of study drug, with an average of 183 days
Primary Number of Participants With Serious Treatment-emergent Adverse Events A serious adverse event (SAE) was any untoward medical occurrence that at any dose was resulting in death, was lifethreatening, requires hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity. SAEs occurring after the first administration of study drug and up to and including 30 days after the last administration of study drug were defined as serious treatment-emergent AEs (TESAEs). Drug-related TESAEs were TESAEs that had "reasonable causal relationship" to the study treatment decided by the investigators. After the first administration of study drug and up to and including 30 days after the last administration of study drug, with an average of 183 days
Primary Number of Participants With Treatment-emergent Adverse Events of Special Interest Any thromboembolic or thrombotic microangiopathic event or any hypersensitivity reaction was an adverse event of special interest (AESI). AESIs occurring after the first administration of study drug and up to and including 30 days after the last administration of study drug were defined as treatment-emergent AESIs. After the first administration of study drug and up to and including 30 days after the last administration of study drug, with an average of 183 days
Primary Number of Participants With Clinically Relevant Abnormalities in Laboratory Values "Clinically relevant "implied the presence of a clinical sign or symptom that required medical action. After the first administration of study drug and up to and including 30 days after the last administration of study drug, with an average of 183 days
