Trial summary

Thalassemia is an inherited blood disorder that can result in mild to severe anemia. Regular blood transfusions, which refresh the healthy red blood cell supply, are one treatment for thalassemia. People with thalassemia often experience pain, but the exact source of pain remains unknown. Read more about this study

About this study

Official title: Assessment of Pain in Transfusion Dependent Patients With Thalassemia During Transfusion Cycles

Thalassemia is an inherited blood disorder that can result in mild to severe anemia. Regular blood transfusions, which refresh the healthy red blood cell supply, are one treatment for thalassemia. People with thalassemia often experience pain, but the exact source of pain remains unknown. This study will examine how pain varies during the blood transfusion cycle in people with thalassemia who are treated with regular blood transfusions.

Read the detailed description

Thalassemia is an inherited blood disorder in which the body makes an abnormal form of hemoglobin-the protein in red blood cells that carries oxygen. People with thalassemia often experience fatigue, shortness of breath, and pain. There have been no previous research studies that have fully examined pain levels in people with thalassemia, and as a result, the sources of pain remain unknown. This study is a substudy of the Assessment of Pain study, which is a Thalassemia Clinical Research Network (TCRN) study that is examining the prevalence and severity of pain in people with transfusion-dependent thalassemia and non-transfusion-dependant thalassemia. This study will enroll a subset of participants from the Assessment of Pain study who have transfusion-dependant thalassemia. The purpose of this study is to examine whether pain varies during the blood transfusion cycle and whether the length of the transfusion cycle affects pain levels in people with transfusion-dependent thalassemia.

Participants will complete daily questionnaires through an automated telephone system to assess pain levels during three blood transfusion cycles. Each transfusion cycle will last between 2 to 4 weeks, depending on the individual needs of the participant, and the cycles will be separated by at least 3 months but no more than 4 months. Prior to each transfusion cycle, study researchers will review participants' medical records for certain blood level measurements.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT00872833
Study groupRoleWhat they receive
age 18-29People age groups 18-29 with transfusion-dependent thalassemia who have reported at least mild degrees of pain during the main Assessment of Pain study.
age 30+People age groups 30+ years with transfusion-dependent thalassemia who have reported at least mild degrees of pain during the main Assessment of Pain study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Report of Pain by Age Group

    Subjects reported whether or not they had pain (yes/no) during each transfusion cycle (data on up to 3 transfusion cycles were collected for each subject). The percent of subject-cycles with pain was calculated for the quartiles of the transfusion cycle.

    Measured: measured daily over the 3 transfusion cycles

Secondary outcomes (1)
  1. Report of Pain by Length of the Transfusion Cycle

    Subjects reported whether or not they had pain (yes/no) during each transfusion cycle (data on up to 3 transfusion cycles were collected for each subject). The percent of subject-cycles with pain was calculated for the quartiles of the transfusion cycle.

    Measured: measured daily over the 3 transfusion cycles

Questions about this trial

What is this clinical trial studying?

An observational study of Thalassemia, run by Carelon Research at 9 sites in 2 countries.

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 4 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 7 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Canada. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Report of Pain by Age Group (time frame: measured daily over the 3 transfusion cycles). 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 7 Oct 2015.
