About this study

Splenectomized thalassemia major subjects were provided with PCV pneumococcal vaccine (Prevenar 13®) at the start of the trial, following which they were randomly assigned to 2 groups (zinc and placebo group). After 8 weeks, the subjects received PPV pneumococcal vaccine (Pneumovax®). Zinc syrup was provided to the zinc group at a dose of 1.5 mg/kg/day (maximum of 50 mg/day). Pneumococcal IgG examinations were conducted at the start of the trial and after 12 weeks.

Read the detailed description

This study is a single blinded randomised-control trial. Splenectomized thalassemia major patient samples were provided with PCV pneumococcal vaccine (Prevenar 13®) at the start of the trial, following which they were randomly assigned to 2 groups (zinc and placebo group). After 8 weeks, the subjects received PPV pneumococcal vaccine (Pneumovax®). Zinc syrup was provided to the zinc group at a dose of 1.5 mg/kg/day (maximum of 50 mg/day). Placebo containing sucrose syrup of the same form, taste, consistency and color was given to the other group. Everyone except the primary researcher are blinded to which of the treatment is placebo and which is actual zinc syrup. Pneumococcal IgG examinations were conducted at the start of the trial and after 12 weeks.

Sample size was measured using:

n1=n2=n= {((Zα+Zβ) Sd)/d}^2 where N = number of subject Za = degree of significance (5%), a = 5% Zb = strength of study (80%). b = 20% Sd = standard deviation d = meaningful difference between the two groups The measured sample size is 816, but due to limited patient total population sampling was used instead.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Zinc, Sucrose and PCV Vaccine in people with Thalassemia and Pneumococcal Infection, run by Fakultas Kedokteran Universitas Indonesia at 1 site in Indonesia.

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 1 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 29 Mar 2017. 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 Indonesia. 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. Some participants in this study may receive a placebo. 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?

Pneumococcal IgG (time frame: week 12). 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 29 Mar 2017.
