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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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 to 45 years (Adult)

Accepts Healthy Volunteers

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
Net Phosphorous Absorption
Time Frame: 10 hours post-dose
Net phosphorous absorption (Lanthanum carbonate period) = phosphorous ingested in meal minus (Rectal effluent phosphorous after Lanthanum carbonate + meal minus Rectal effluent phosphorous after fasting). Net phosphorous absorption (Sevelamer Carbonate period) = Phosphorous ingested in meal minus (Rectal effluent phosphorous after Sevelamer carbonate + meal minus Rectal effluent phosphorous after fasting). Net phosphorous absorption (Meal only period) = Phosphorous ingested in meal minus (Rectal effluent phosphorous after meal only minus Rectal effluent phosphorous after fasting).
10 hours post-dose

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.
Outcome Measure
Measure Description
Time Frame
Net Phosphorous Binding
Time Frame: 10 hours post-dose
Net Phosphorous Binding (Lanthanum carbonate period) = Rectal effluent phosphorous after Lanthanum carbonate + meal minus Rectal effluent phosphorous after meal only. Net Phosphorous Binding (Sevelamer carbonate period) = Rectal effluent phosphorous after Sevelamer carbonate + meal minus Rectal effluent phosphorous after meal only.
10 hours post-dose
Net Calcium Absorption
Time Frame: 10 hours post-dose
Net Calcium Absorption (Lanthanum carbonate period) = Calcium ingested in meal minus (Rectal effluent calcium after Lanthanum carbonate + meal minus Rectal effluent calcium after fasting). Net Calcium Absorption (Sevelamer Carbonate period) = Calcium ingested in meal minus (Rectal effluent calcium after Sevelamer carbonate + meal minus Rectal effluent calcium after fasting). Net Calcium Absorption (Meal only period) = Calcium ingested in meal minus (Rectal effluent calcium after meal only minus Rectal effluent calcium after fasting).
10 hours post-dose

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
