Multiple Escalating Dose Study of BAY1093884 in Adults With Hemophilia A or B With or Without Inhibitors

November 26, 2020 updated by: Bayer
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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Subjects with a past history of inhibitors (any inhibitor titer) are eligible.
  • Age ≥18 years.
  • Documentation of ≥4 bleeding episodes (any type or location of bleeds, treated or not) within the 6 months prior to screening.
  • For subjects on prophylaxis: Willingness to interrupt ongoing prophylaxis.
  • For subjects on immune tolerance induction (ITI): Willingness to interrupt ongoing ITI.

Exclusion Criteria:

  • History of any other coagulation disorder (particularly disseminated intravascular coagulopathy or combined FVIII/FV deficiency) or platelet disorder.
  • History of diseases related to venous thromboembolic events (e.g., pulmonary embolism, deep vein thrombosis, thrombophlebitis) or thrombotic microangiopathy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Drug-related Treatment-emergent Adverse Events
Time Frame: 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
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
Number of Participants With Serious Treatment-emergent Adverse Events
Time Frame: 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
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
Number of Participants With Treatment-emergent Adverse Events of Special Interest
Time Frame: 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
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
Number of Participants With Clinically Relevant Abnormalities in Laboratory Values
Time Frame: 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
"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
