May 23, 2023 updated by: Donat R. Spahn

Ferric Carboxymaltose With or Without Phosphate Substitution for the Treatment of Iron Deficiency or Iron Deficiency Anemia Before Elective Surgery - the DeFICIT Trial

This is a confirmatory trial to establish superior serum phosphate stability associated with use of Phoscap® compared with placebo as a supplement for treatment of iron deficiency or iron deficiency anemia with Ferinject® before elective surgery.

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.

Detailed Description

Iron deficiency anemia is a global health problem most commonly caused by excessive blood loss, impaired intestinal iron absorption, or chronic inflammation. In the perioperative setting, intravenous ferric carboxymaltose allows efficient treatment of preoperative iron deficiency and anemia. Recent studies have implied that ferric carboxymaltose might cause hypophosphatemia. Notably, hypophosphatemia has been associated with less muscle strength, which may influence early post-surgery recovery of patients. Additional oral phosphate supplementation may alleviate this hypophosphatemia.

This is a confirmatory trial to establish superior serum phosphate stability associated with use of Phoscap® compared with placebo as a supplement for treatment of iron deficiency or iron deficiency anemia with Ferinject® before elective surgery.

This is also a confirmatory trial to establish non-inferior efficacy of Phoscap® compared with placebo for the treatment of iron deficiency or iron deficiency anemia with Ferinject®; and to establish superior core muscle strength associated with the use of Phoscap® compared with placebo.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Informed Consent as documented by signature (Appendix 5: Informed Consent Form)
  • Male or female ASA 1 to 3 patients, at least 18 years old
  • Scheduled for an elective major abdominal or thoracic surgery.
  • Patients with isolated iron deficiency (defined as hemoglobin concentration (Hb) > 130 g/l, and plasma Ferritin < 100 ng/ml or TSAT < 20%), or iron deficiency anemia (defined as Hb 100-130 g/l, and plasma Ferritin < 100 ng/ml or TSAT < 20%).
  • Patients scheduled to be hospitalized ≥ 3 days.

Exclusion Criteria:

  • Patients with known anaphylactic reactions to parenteral iron products. Patients with allergy/hypersensitivity to any contents of Ferinject® or Phoscap®.

  • Patients with known urinary tract infections with urea-splitting bacteria.
  • Patients with known diseases influencing phosphate, calcium or vitamin D homeostasis (e.g. Hyperparathyroidism, X-linked hypophosphatemia, renal tubular acidosis).
  • Patients taking medication significantly influencing phosphate, calcium or vitamin D homeostasis (e.g. vitamin D substitution > 800 I.E. per day in the last 4 months, pre-existing phosphate substitution, phosphate binders).

  • Lack of safe contraception, defined as: Female participants of childbearing potential, not using and not willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or who are not using any other method considered sufficiently reliable by the investigator in individual cases (Female participants who are surgically sterilized / hysterectomized or post-menopausal for longer than 2 years are not considered as being of child bearing potential),
  • Known or suspected non-compliance, drug or alcohol abuse.
  • Participation in another study with investigational drug within the 30 days preceding and during the present study.
  • Any patient judged by the Principal Investigator or Sub-Investigator to be inappropriate for the trial for any other reason.

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
Establish superior serum phosphate stability
Time Frame: 3 years
The primary endpoint is superior serum phosphate stability. The investigators measure perioperative phosphate concentrations in participants during the follow-up visits and compare the results between verum and placebo group.

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.
