Concise methodology:
- Study Population: Children with hemophilia A who received treatment at KCMH from May 2015 to March 2016 will be enrolled in this study. The consent will be obtained before the study.
- Observation and measurement:
- History, interesting clinical data and laboratory data will be recorded in Clinical record Form (CRF)
- Measurement:
- Complete blood count (CBC), Factor VIII level, Factor VIII inhibitor level ii. Number of breakthrough bleedings, number of hospital stay and day-off from school iii. Joint score from Hemophilia Joint Health Score 2.1 iv. EQ-5D-5L quality of life assessment score
- Data analysis: The p-value of less than 0.05 will be considered statistically significant. Mann-Whitney test will be used to test correlation of these variables (CBC, Factor VIII level, Factor VIII inhibitor level, Number of breakthrough bleedings, number of hospital stay, day-off from school, Hemophilia Joint Health Score 2.1, EQ-5D-5L quality of life assessment score) Sample size: 16 patients
Potential impacts:
The outcomes of different factor VIII concentrate dose between 15-20 U/kg/dose 2 times/week and 35-40 U/kg/dose 1 time/week will be revealed. These outcomes include number of breakthrough bleeding, number of hospital stay, day-off from school, joint health and quality of life. The result of this study will guide further study on optimal dose and duration of factor VIII treatment of hemophilia A patients in the future.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing FVIII in people with Hemophilia A, run by Chulalongkorn University at 1 site in Thailand.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Annualized bleeding rate per year (time frame: 10 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2016.
