Study summary

This is a phase III multi-centre study in three periods: the first period is a phosphate binder washout for 4 weeks, the second period is an open-label, randomised, parallel group, flexible dose, the third period is a placebo-controlled withdrawal comparing MCI-196 with placebo for 4 weeks.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male or female, 18 years of age or over
  • Clinically stable haemodialysis or peritoneal dialysis
  • Stable phosphate control
  • On a stabilised phosphorus diet
  • Female and of have a negative serum pregnancy test.
  • Male subjects must agree to use appropriate .

Exclusion criteria

Exclusion Criteria:

  • Current medical comorbidities, which may substantially compromise subject safety, or expose them to undue risk, or interfere significantly with study procedures and which, in the opinion of the Investigator, makes the subject unsuitable for inclusion in the study.
  • (BMI) \<=16.0 kg/m2 or >=40.0 kg/m2
  • A current or history of significant gastrointestinal motility problems
  • A positive test for 1 and 2 antibodies
  • A history of substance or alcohol abuse within the last year.
  • Seizure disorders
  • A history of drug or other allergy
  • A temporary catheter as a vascular access
  • Participated in a clinical study with any experimental medication in the last 30 days or an experimental biological product within the last 90 days prior to signing of
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jun 2007, a primary completion of Nov 2009 and a completion of Nov 2009. It does not say whether these dates are actual or estimated.

Results were first posted in Oct 2014, 4 years 11 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
