Detailed Description

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common causes of end stage renal disease (ESRD), affecting an estimated 0.2% of population. Of ADPKD patients, 58% in 15-24 year, 85% in 25-34 year, and 94% in 35-46 year olds suffer from polycystic liver in addition to polycystic kidneys. Several anti-proliferative drugs have been used in clinical trials to stop cyst growth both in liver and kidneys. Among them, octreotide and sirolimus have been shown to be one of the most promising drugs to reduce cyst volume. Sirolimus already has been used as one of the most potential oral immunosuppressants. Moreover, the serum trough level is quite easy to measure. Sirolimus is the mTOR inhibitor that has been proven to be effective in reducing cyst growth both in animal models. However, its efficacy and safety is not well proven in previous studies. This is a open-label, prospective study to evaluate the effectiveness and safety of Sirolimus to reduce cyst growth in ADPKD patients with massive polycystic liver.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
