Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Docarpamine (DCP), an orally available dopamine prodrug. Docarpamine contains reversible chemical modifications of the catechol and amino groups of dopamine.
The study will assess the effect of Docarpamine (DCP) treatment on ascites formation in cirrhotic subjects with Refractory Ascites (RA), by examining the frequency of large volume paracentesis (LVP) and the volume of ascitic fluid drained. All subjects will participate in a 90-day open-label treatment period, followed by a 90-day follow-up period of additional data collection from medical records. Ascites history (relevant medications, large volume paracentesis (LVP) dates, and volume of drained fluid) for the 90 days prior to treatment and the 90 days after treatment will be collected and used for comparison with on-treatment frequency and volume.
The study will be conducted in two parts. At the start of the study, subjects will be enrolled into Part A. When a sufficient number of subjects have been enrolled into Part A to provide information about preliminary efficacy, safety, and exposure, additional subjects will then be enrolled into Part B.
The study consists of two parts:
Part A: Subjects enrolled into Part A will participate in a 90-day open-label treatment period, followed by a 90-day follow-up period of additional data collection from medical records. Ascites history (relevant medications, large volume paracentesis (LVP) dates, and volume of drained fluid) for the 90 days prior to treatment and the 90 days after treatment will be collected and used for comparison with on-treatment frequency and volume.
After screening and enrolment, subjects under Amendment 2 will begin V0 (Exposure Assessment Visit). At this visit, each subject will be administered one single dose of 750 mg Docarpamine (DCP) orally. Pharmacokinetic assessments will be performed to evaluate each subjects optimal dose for the study duration.
Following V0, Dosing in Part A will be either 750 mg or 1500 mg three times a day (TID) daily for 90 days, depending on V0 PK assessment result.
Part B: Subjects enrolled into Part B will participate in a 63 day (9 week) open-label treatment period: 7 days on Docarpamine (DCP) 750 mg three times a day (TID), followed by 56 days (8 weeks) on Docarpamine (DCP) 1500 mg TID. Ascites history (medication, large volume paracentesis (LVP) dates, and volume of drained fluid) for the 63 days prior to treatment will be collected and used for comparison with on-treatment large volume paracentesis (LVP) frequency and volume. Subjects assessed as showing a response to treatment (either a reduction in large volume paracentesis (LVP) volume, and/or a decrease in the frequency of large volume paracentesis (LVP) compared to prior history) will also be observed post-treatment for 63 days. Subjects who do not show a response during the treatment period will not be followed for the post-treatment period.
In Part B, dosing for all subjects will be 750 three times a day (TID) for the first 7 days, and 1500 three times a day (TID) for the remainder of the treatment period

Throughout the study
Secondary outcome [1] 378318 0
Part 1/ Part 2: Safety & tolerability will be assessed by Medical History, Physical Exam, Ascites Grade, Hepatic Encephalopathy, 12-lead ECG, vital signs, hematology, blood chemistry, liver function, coagulation tests, urine test and as well as assessing AEs, and concomitant medications and procedures.
Timepoint [1] 378318 0
Part A: Performed at baseline, at each LVP visit and at day 7, day 14, day 21, day 28, day 56, day 90, and day 120.
Part B: Performed at baseline, at each LVP visit and at day 8, day 15, day 22, day 29, and day 63.
Secondary outcome [2] 379683 0
Part A/ Part B: Docarpamine pharmacokinetics. Parameters to be examined: maximum observed plasma concentration after single and repeat dosing (Cmax), Area under the curve over the dosing interval after first dose on Day 1 (AUCtau), time to maximum observed plasma concentration after single and repeat dosing (Tmax)
Timepoint [2] 379683 0
Part A: Pharmacokinetic samples will be obtained at Visit 0 (baseline), Visit 1 (Day 1: pre-dose, 1 hours ± 5 minutes, 1.5 hours ± 5 minutes, 2 hours ± 5 minutes, 2.5 hours ± 5 minutes, 3 hours ± 5 minutes, 3.5 hours ± 5 minutes and 4 hours ± 10 minutes) for those subjects who will receive the 1500mg dose. The same PK sample schedule will be collected on Visit 7 (Day 7), although this may take place as late as Visit 10 (Day 28).

Part B: Pharmacokinetic samples will be obtained on Day 8: pre-dose, 1 hours ± 5 minutes, 2 hours ± 5 minutes, 2.5 hours ± 5 minutes, 3 hours ± 5 minutes, 3.5 hours ± 5 minutes and 4 hours ± 10 minutes. The same PK sample schedule will also be collected on Day 15, although this may take place as late as Day 29 if necessary to accommodate subject and site scheduling.
