Trial summary

A phosphate supplement is part of the treatment of patients with the refeeding syndrome (RFS). It is not known, if the generalized edema also affects the intestine to decrease absorption. The aim was to investigate, if oral treatment is possible in mild to moderate RFS. Read more about this study

About this study

Official title: Absorption of Orally Ingested Phosphate in Head and Neck Cancer Patients With and Without Refeeding Syndrome

A phosphate supplement is part of the treatment of patients with the refeeding syndrome (RFS). It is not known, if the generalized edema also affects the intestine to decrease absorption. The aim was to investigate, if oral treatment is possible in mild to moderate RFS. In a randomized crossover design 12 hospitalized head-neck cancer patients ingested four oral solutions of phosphate in two-day periods. In a low-dose period the investigators compared five mmol phosphate from either skimmed milk or Di-sodiumphosphate-di-hydrate and potassium di-hydrogens-phosphate with black currant flavor (PBC), and in a high-dose period 20 mmol from either Addiphos® or the PBC-solution. P-phosphate was measured two and four hours after the ingestion, the urinary excretion after four hours.

P-phosphate significantly increased after PBC in both the low- and high-dose and Addiphos®, but not after skimmed milk. The increase was larger after Addiphos® than the PBC-solution. There was no difference in the increase between the patients with low p-phosphate and those with normal values, and no correlation between baseline p-phosphate and percent increase. There was no group difference in the urinary excretion of phosphate. The investigators conclude that phosphate can be readily absorbed after oral administration, but skimmed milk can´t be recommend for this purpose.

Read the detailed description

The study was designed as a non-blinded, randomized, controlled crossover intervention study.

A total of 12 hospitalized adult head-neck cancer patients, 11 men and one woman, gave informed consent to participate. Six patients with a p-phosphate between 0.30-0.80 mmol/l were included as well as six patients (controls) with a p-phosphate in the normal range of 0.80-1.50 mmol/l. The control patients matched the hypophosphatemic patients regarding sex, age (± 10 years) and alcohol habits. Patients with diagnosed renal failure, edema, diabetes, liver failure, gastrointestinal disorders, pregnant and lactating women were excluded. None of the patients had phosphate supplementation within the previous 24 h. Randomization determined the order of the phosphate supplements divided into low-doses of five mmol followed by high-dose 20 mmol both for two day periods. Accordingly, four days intervention with a different phosphate supplement every day.

In the low-dose period supplements consisted of a daily dose of five mmol phosphate from skimmed milk (97 mg phosphorus and 0.1 g fat/100 ml) or Phosphate with black currant flavor (PBC) (disodiumphosphatedihydrate and potassiumdihydrogenphosphate, 1 mmol phosphate/ml). In the high-dose period supplements consisted of 20 mmol phosphate from Addiphos® (Fresenius-Kabi) (disodiumphosphate, potassiumdihydrogenphosphate, potassiumhydroxide, 2 mmol/ml) and PBC. The patients fasted six hours prior to baseline blood- and urine samples and during the four hours of the trial. Blood samples were repeated after two and four hours, urine after four hours. The interval between blood samples was determined on the basis of an animal experiment, which described phosphate absorption measured in plasma 1 hour after administration (10). The interval was extended to 2 hours due to the risk of gastric retention.

The primary outcome was the changes in p-phosphate. The secondary outcomes were changes in u-phosphate and changes in p-potassium, p-magnesium and p-sodium. The paired data were tested by the Wilcoxon test. Non paired data were tested by the Mann-Whitney test. Spearman-rank correlation test was used, and the statistical analyses were performed with STATA version 13.1 (StataCorp LP, USA, Texas).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing phosphate orally in people with Refeeding Syndrome and Cancer of the Head and Neck, run by Jens Rikardt Andersen at 1 site in Denmark.

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 1 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 26 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

plasma phosphate (time frame: 4 hours). 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 26 Aug 2016.
