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

  • ADULT
  • OLDER_ADULT
  • CHILD

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male patients
  • Severe Hemophilia A (FVIII:C <1%)
  • No previous treatment with FVIII concentrates or other blood products containing FVIII

Exclusion Criteria:

  • Diagnosis with a coagulation disorder other than Hemophilia A
  • Severe liver or kidney disease
  • Concomitant treatment with any systemic immunosuppressive drug

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

EXPERIMENTAL: Human cl rhFVIII
Biological: Human cl rhFVIII

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
Immunogenicity of Human-cl rhFVIII: Incidence of Inhibitors
Time Frame: maximum 5 years (100 exposure days)
The number of patients developing FVIII inhibitors was observed during the observation period by assessing inhibitor development using the modified Bethesda assay (Nijmegen modification). The definitions for thresholds were ≥0.6 to <5 BU/mL for a "low titre" inhibitor and ≥5 BU/mL for a "high-titre" inhibitor.
maximum 5 years (100 exposure days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequency of Spontaneous Break-through Bleeds
Time Frame: Maximum 5 years (100 exposure days)
The annualized bleeding rate (ABR) was calculated during inhibitor-free periods for spontaneous bleeding events (BEs) during prophylactic treatment with Human cl rhFVIII
Maximum 5 years (100 exposure days)
Efficacy of Human-cl rhFVIII for the Treatment of Bleeds
Time Frame: Maximum 5 years (100 exposure days)
A personal efficacy assessment to assess the efficacy of Human-cl rhFVIII for the on-demand treatment of bleeding episodes. Efficacy was assessed using a four-point scale (excellent, good, moderate, none).
Maximum 5 years (100 exposure days)
Efficacy of Human-cl rhFVIII for Surgical Prophylaxis
Time Frame: Maximum 5 years (100 exposure days)
An overall efficacy assessment to assess the efficacy of human-cl rhFVIII in surgical prophylaxis of minor and major surgeries. The efficacy assessment was analyzed using a four-point scale (excellent, good, moderate, none).
Maximum 5 years (100 exposure days)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Occurrence of Any Adverse Event (AE)
Time Frame: 5 years
The frequency of AEs, as monitored throughout the whole study by the number of patients with at least one adverse event occurrence.
5 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
