Read the detailed description
Chronic kidney disease (CKD) is a growing public health problem that increases risks of endstage renal disease (ESRD), cardiovascular disease (CVD), fractures, and death, and it poses an enormous financial burden on the US health system. Existing therapies modestly impact outcomes. Novel strategies targeting CKD-specific mechanisms are urgently needed to improve health and reduce cost.
CKD is complicated by disordered mineral metabolism, characterized by abnormal calcium and phosphate homeostasis, calcitriol and klotho deficiency, and elevated levels of parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23). Elevated FGF23 is the earliest and most common manifestation of disordered mineral metabolism. Observational studies report independent associations between elevated phosphate and FGF23 blood levels and increased risks of ESRD, CVD and death. As potential explanatory mechanisms, phosphate excess induces arterial stiffness due to vascular calcification, and FGF23 excess contributes directly to the pathogenesis of left ventricular hypertrophy (LVH). Together, these effects promote CVD events and death.
Dietary phosphate absorption is a modifiable determinant of phosphate and FGF23 levels. Small studies of short duration suggest that phosphate binders and dietary phosphate modification in CKD can lower phosphate and FGF23 blood levels by reducing paracellular absorption of phosphate in the gut. However, animal studies demonstrate that compensatory upregulation of transcellular phosphate absorption via the sodium phosphate co-transporter, NPT2b, reduces the efficacy of these approaches. Since nicotinamide lowers plasma phosphate by reducing gut expression of NPT2b,the investigators hypothesize that use of nicotinamide combined with phosphate binders on a background of dietary phosphate moderation will most effectively reduce phosphate and FGF23 blood levels in CKD. The investigators plan to advance this approach in future randomized clinical trials.
The objective of this study is to perform a detailed physiologic study of healthy volunteers to assess the short-term effects of nicotinamide alone, lanthanum carbonate alone, or both in combination, on phosphate homeostasis. The results from healthy volunteers will provide information needed for optimal design of studies for patients with CKD.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Nicotinamide and Lanthanum Carbonate in people with Healthy, run by Northwestern University at 1 site in United States.
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 16 inclusion and 17 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 23 Feb 2024. 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 United States. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Feb 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change in Intact FGF23 (time frame: Approximately 3 weeks.). 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 23 Feb 2024; AzTrials last refreshed its copy on 27 Oct 2026.
