Inclusion Criteria

  • Ability to provide informed consent to participate in the study.
  • Healthy volunteers, age 19-45 inclusive.
  • Subject must be willing to comply with applicable contraceptive requirements of the protocol
  • Female subjects must have a negative pregnancy test
  • Satisfactory medical assessment with no clinically significant or relevant abnormalities in medical history, physical examination, vital signs, ECG and laboratory evaluation.

Exclusion Criteria

  • Current or recurrent disease that could affect the action, absorption or disposition of the investigational products utilized in this study, or could affect clinical or laboratory assessments.
  • Current or relevant previous history of physical or psychiatric illness, any medical disorder that may require treatment or make the subject unlikely to fully complete the study, or any condition that presents undue risk from the investigational product or study procedures.
  • Significant illness within 2 weeks of the first dose of investigational product.
  • Current use of any medication with the exception of hormonal replacement therapy or hormonal contraceptives within 14 days of first dose of investigational product.
  • Known or suspected intolerance or hypersensitivity to the investigational product(s) or mannitol solution, closely related compounds or any of the stated ingredients.

  • A positive human immunodeficiency virus (HIV) antibody screen, Hepatitis B surface antigen (HBsAg) or Hepatitis C virus (HCV) antibody screen.
  • Use of tobacco in any form or other nicotine-containing products in any form. Ex-users must report that they have stopped using tobacco for at least 30 days prior to receiving the first dose of investigational product.
  • Routine consumption of more than two units of caffeine per day or subjects who experience caffeine withdrawal headaches.
  • Donation of blood or blood products within 60 days prior to receiving the first dose of investigational product.
  • Use of another investigational product within 30 days prior to receiving the first dose of investigational product or active enrolment in another drug or vaccine clinical study.
  • An inability to follow a standardized diet and/or meal schedule, as required during the study.

Outcomes

Primary Outcome Measures

Net Phosphorous Absorption
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).

Secondary Outcome Measures

Net Phosphorous Binding
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.
Net Calcium Absorption
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).
