About this study

Official title: A Randomized, Placebo-controlled Comparator Trial of IV vs Oral Iron Treatment of Iron Deficiency Anemia in the Post-operative Bariatric Surgical Patient

The aim of the study is to compare two accepted treatments for iron deficiency anemia (oral ferrous sulfate and intravenous ferumoxytol) for efficacy and speed of response in the treatment of iron deficiency anemia (IDA) in the post-operative bariatric surgical patient. In this study, 104 bariatric surgical post-operative patients will be randomly assigned 52 each to oral or 52 to a single dose IV iron treatment using double-blind procedures.

Read the detailed description

Rationale for study: The preponderance of published evidence reports superior efficacy and decreased toxicity of intravenous iron compared to oral iron in correcting anemia and iron parameters in published trials of bariatric surgery patients. Intravenous, and not oral, iron ensures adequate delivery and avoids gastrointestinal toxicities, which may be especially burdensome in these patients who require optimal levels of energy to maintain prudent exercise programs recommended by patients' bariatric practitioners. Uncontradicted published evidence reports safety and efficacy of complete replacement doses of intravenous iron administered in one or two doses of either low molecular weight iron dextran, ferumoxytol, ferric carboxymaltose or iron isomaltoside. A common feature of all studies extant is the lack of reported serious adverse events. Even in patients with minimally invasive procedures such as gastric banding or stapling in whom oral iron may be tolerated, given the often present multiple gastrointestinal perturbations, intravenous iron may simplify care.

Drugs used: The investigators propose to use and FDA approved IV iron preparation - ferumoxytol, administered as two doses (over a interval of 2 to 7 days), each 510 mg over fifteen minutes based on published prospective safety and efficacy data and compare the effectiveness of the treatment to the American Metabolic and Bariatric Associations recommended treatment for iron deficiency anemia in the post-operative bariatric patients of oral iron ferrous sulphate 325 mg twice daily for 6 weeks.

What is being measured

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

  1. Resolution of anemia in oral vs. IV iron as assessed by Clinical Global Impression (CGI) - 2 score

    The CGI-2 is a one-item questionnaire which asks how participants feel now compared to before receiving treatment. It has a scoring of 1 to 7 with 1 meaning much better and 7 meaning very much worse

    Measured: 6 weeks

  2. Resolution of anemia in oral vs. IV iron as assessed by ferritin level

    Participants will be assessed after six weeks to see if there is a resolution of anemia following the treatment with oral or IV iron. This will be determined by the ferritin level. Ferritin > 20% will be the cutoff for resolution of anemia.

    Measured: 6 weeks

  3. Resolution of anemia in oral vs. IV iron as assessed by TSAT

    Participants will be assessed after six weeks to see if there is a resolution of anemia following the treatment with oral or IV iron. This will be determined by TSAT level. TSAT > 19% will be the cutoff for resolution of anemia.

    Measured: 6 weeks

  4. Time (weeks) to treatment response as assessed by CGI-2 score

    The CGI-2 is a one-item questionnaire which asks how participants feel now compared to before receiving treatment. It has a scoring of 1 to 7 with 1 meaning much better and 7 meaning very much worse. This will be used in assessing the time in weeks when participant noticed a change after receiving treatment.

    Measured: 6 weeks

  5. Time (weeks) to treatment response as assessed by ferritin level

    Participants will be assessed after six weeks to identify what time (in weeks) ferritin level was > 20% following the treatment with oral or IV iron

    Measured: 6 weeks

  6. Time (weeks) to treatment response as assessed by TSAT

    Participants will be assessed after six weeks to identify what time (in weeks) TSAT level was > 19% following the treatment with oral or IV iron

    Measured: 6 weeks

Secondary outcomes (2)
  1. Need for continued treatment as assessed by ferritin level

    Participants will be assessed after a year to see if participants require continued treatment following the treatment with oral or IV iron. This will be determined by the ferritin level. Ferritin > 20% will be the cutoff for no further need for treatment.

    Measured: 1 year

  2. Need for continued treatment as assessed by TSAT

    Participants will be assessed after a year to see if participants require continued treatment following the treatment with oral or IV iron. This will be determined by TSAT level. TSAT > 19% will be the cutoff for no further need for treatment.

    Measured: 1 year

Model description
The study is a randomized, comparative double blind, double dummy study to evaluate efficacy and time course of treatment response of bariatric surgical patients found to have IDA, three months or greater following bariatric surgery (Roux-en Y gastric bypass and vertical sleeve gastrectomy) over 6 weeks with a 46-week follow-up extension. Two medications and placebos will be used with equal random assignment to both groups * Ferumoxytol intravenous (IV) 1020 mg as - 2 vials of 510 mg (510 mg IV over 15 minutes) each given 2-7 days apart. * Ferrous sulfate 325 mg (oral) tabs morning and evening. * Placebo: oral vitamin C 500 mg tabs, saline infusion

Questions about this trial

What is this clinical trial studying?

A study testing Ferumoxytol, Ferrous sulfate and Oral vitamin C in people with IDA in the Post-bariatric Surgical Patient, run by Johns Hopkins University.

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 5 inclusion and 12 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: withdrawn, as of the sponsor's last update on 11 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Resolution of anemia in oral vs. IV iron as assessed by Clinical Global Impression (CGI) - 2 score (time frame: 6 weeks). The study lists 6 primary outcomes in all. 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 11 Sep 2019.
