Study Details

Study Description

Brief Summary

This clinical trial compares a combination of two drugs that constrict blood vessels (Octreotide LAR and Midodrine) to albumin after large volume paracentesis. Subjects have cirrhosis and ascites.

Condition or Disease Intervention/Treatment Phase
  • Drug: Albumin
  • Drug: Intravenous Saline Infusion (Albumin placebo)
  • Drug: Midodrine
  • Drug: Oral tablet (Midodrine placebo)
  • Drug: Octreotide LAR
  • Drug: Saline injection (Octreotide LAR placebo)
  • Procedure: Large Volume Paracentesis
Phase 4

Detailed Description

This prospective, placebo-controlled, randomized, clinical trial compares the effect of a combination of vasoconstrictors (octreotide plus midodrine) to albumin on the time to recurrence of ascites in patients with refractory ascites treated with large volume paracentesis. The treatment allocation ratio for the two treatment arms is 1:1 using a stratified random permuted block design. Subjects are patients 18-80 years old with cirrhosis and ascites who are stratified according to the presence or absence of renal dysfunction at the time of randomization. Measurements include blood pressure, weight, girth, abdominal ultrasound, forearm blood flow, plasma renin activity, angiotensin, and aldosterone, repeated during a 6 month period.

    Study Results

    Participant Flow

    Recruitment Details Between October 2003 and June 2010, about 200 patients with cirrhosis and ascites were screened, of which, only 29 met inclusion criteria. Twenty five patients (13 control, 12 study group) were included in the analysis.

    Statistical Analysis Overview Comparison Group Selection Albumin (Control Group), Vasoconstrictor (Treatment Group)
    Comments Initial estimation: median time to recurrence of ascites of 38 days in the study group and 20 days in the control group in a fixed duration of 6 months (5% type-I error (2 sided) and an 80% power). However, due to low accrual and based on randomized trials using vasoconstrictors in the prevention of PCD and a study that showed that midodrine leads to a significant improvement in effective arterial blood volume, each of which had sample sizes of 24-25 patients,we decided on a sample size of 30.

    Limitations/Caveats

    Difficulty to enroll patient population lead to small sample size. Midodrine not titrated for a goal increase in mean arterial pressure. Blood tests for day 6 assessment of post paracentesis circulatory dysfunction not available for all patients.
