Prevention of Vaso-occlusive Painful Crisis by Using Omega-3 Fatty Acid Supplements (OM3FA)

August 14, 2015 updated by: Salam Alkindi, Sultan Qaboos University

Omega 3 Fatty Acid Therapy for Prevention of Vaso-occlusive Crisis and Manifestations in Omani Patients With Sickle Cell Disease

140 SCD patients [70 on Hydroxyurea] will receive Omega-3 capsules whereas another 140 SCD patients [70 on Hydroxyurea] will receive placebo and will be recruited from the Sultan Qaboos University Hospital [SQUH] haematology specialty clinics. Patients will be randomized in a 1:1 ratio to receive placebo or Omega-3 for 52 weeks. The aim is to investigate the therapeutic potential of omega-3 fatty acids in the prevention of vaso-occlusive crisis in Omani patients with sickle cell disease[SCD].

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

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

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

9 years to 66 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Moderate to severe Sickle cell disease patients.
  • Patients already receiving Hydroxyurea[HU] are eligible for the study.

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
Frequency of VOC
Time Frame: 52 weeks
Reduction of the number of Emergency and Hospital visits for VOC episodes compared to the previous 52 weeks
52 weeks
Severity of VOC
Time Frame: 52 weeks
Reduction in the average visual analog score for pain with scores ranging from 0[no pain] to 10[worst possible pain] recorded during VOC episodes compared to the previous 52 weeks
52 weeks
Duration of Hospitalization
Time Frame: 52 weeks
Reduction in the number of days in hospital with VOC pain compared to the previous 52 weeks
52 weeks

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
Red blood cells membrane fatty acids profile
Time Frame: 52 weeks
Measurement of red blood cell membrane ethanolamine phosphoglyceride[DHA, EPA, AA] at baseline and after 52 weeks intervention period.

Primary Completion (Anticipated)

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.
