About this study
Official title: Multicenter, Randomized, Double-Blind, Placebo- Controlled, Parallel Group, Efficacy and Safety Study to Evaluate the Effects of Oral Administration of Lixivaptan in Patients With Congestive Heart Failure
The purpose of this study is to evaluate the effects of oral lixivaptan capsules in patients with congestive heart failure.
Read the detailed description
Diuretics are used extensively in the treatment of patients with CHF, and their efficacy is well established. However, there is a tendency for currently used diuretics to increase afterload and deplete electrolytes, and in many patients ventricular function continues to deteriorate over time.
Loop diuretics, such as furosemide, also have known negative effects on renal function reducing the glomerular filtration rate, and have been shown to activate the RAA system.
Lixivaptan is a potent, non-peptide selective antagonist of the vasopressin V2 receptor.
Lixivaptan treatment results in increased free water excretion, thus decreasing urine osmolality, increasing urine flow, and increasing serum osmolality. Short-term treatment with lixivaptan has demonstrated improved fluid management and electrolyte balance in HF patients.
This study was designed to assess the effects of vasopressin blockade with lixivaptan in patients with CHF with volume overload. A placebo-control arm will allow for assessment of the effect of lixivaptan in addition to standard diuretic therapy as compared with standard diuretic therapy alone.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
To assess the efficacy and safety of lixivaptan treatment in congestive heart failure (CHF) patients with volume expansion. (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01055912, which also lists 1 linked publication.
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 28 Jun 2011; AzTrials last refreshed its copy on 8 Nov 2026.
