About this study

Official title: A Phase II, Multicenter, Single-Blind, Randomized Study of the Safety and Effectiveness of SANGUINATE™ Versus Normal Saline in Adult Sickle Cell Disease Patients With Vaso-Occlusive Crisis (VOC)

Safety and effect of SANGUINATE on Sickle Cell Disease patients experiencing a vaso-occlusive crisis who are admitted to the hospital for treatment.

Read the detailed description

A single-blind, multicenter, randomized, placebo-control study in which 30 Sickle Cell disease patients having a vaso-occlusive crisis will either receive SANGUINATE 320 mg/kg/patient (8 mL/kg/patient) or Normal Saline on Day 1 (Visit 1) and Day 2 (Visit 2) infused over 2 hours each day. Patients are to remain in the hospital for up to 7 days but can be discharged at any time after receiving the second dose of SANGUINATE, provided their vaso-occlusive crisis has resolved and the patient has completed discharge procedures. Patients will have a follow-up phone call 7 days after discharge from the hospital to obtain safety, concomitant medication and pain assessments.

What is being measured

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

  1. Time to readiness for discharge from in hospital stay following treatment with SANGUINATE and Normal Saline.

    Defined as the patient's response that their pain episode has improved enough for discharge from the hospital, or the Investigator's assessment that the patient is ready for discharge from the hospital.

    Measured: Up to 7 Days

Secondary outcomes (7)
  1. Safety of treatment as defined by changes in vital signs, electrocardiographic, biochemical, hematological, and urinalysis measures, as well as reported increases in pain and other reported adverse events

    Composite endpoint with multiple vital signs, ECGs, echocardiograms, clinical assessments and bio-analytical lab measurements over the 7 day time frame

    Measured: Up to 7 Days

  2. Proportion of patients who develop acute chest syndrome (ACS) during the study.

    Measured: Up to 14 Days

  3. Proportion of patients who are re-hospitalized for their vaso-occlusive crisis episode.

    Measured: Up to 7 Days

  4. Total length of stay (LOS) following treatment of SANGUINATE versus Normal Saline.

    Measured: Up to 7 Days

  5. Percent reduction in total pain medication required during in-hospital stay following treatment with SANGUINATE and Normal Saline.

    Measured: Up to 7 Days

  6. Percent reduction in pain score utilizing a visual analog scale following treatment with SANGUINATE and Normal Saline.

    Measured: Up to 7 Days

  7. Reduction in the level of C-Reactive Protein following treatment of SANGUINATE versus Normal Saline.

    Measured: Up to 7 Days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SANGUINATE 320 mg/kg and Normal Saline in people with Anemia, Sickle Cell, run by Prolong Pharmaceuticals at 4 sites in 4 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 8 inclusion and 11 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 23 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Colombia, Dominican Republic, Honduras, Panama. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Time to readiness for discharge from in hospital stay following treatment with SANGUINATE and Normal Saline. (time frame: Up to 7 Days). 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 23 May 2018.
