详细描述
This is an open-label multicenter, long-term extension safety study to evaluate the safety of IV CR845 administered after each dialysis session over a Treatment Period of up to 52 weeks. This study will consist of a Screening Visit, a 52 week Treatment Period, and a Follow-up Visit. Informed consent will be obtained prior to performing any study-specific procedures. All patients will have a Screening Visit, which can be performed anytime within 14 days prior to the first dose of study drug, to confirm eligibility.
Clinical laboratory tests, electrocardiograms (ECGs), vital signs, adverse events, and concomitant medications will be monitored throughout the study. Blood samples for inflammatory biomarkers will be collected from all patients prior to dialysis on Day 1 and periodically until the End of Treatment or Early Termination Visit. Blood samples will also be collected periodically for clinical laboratory tests.

- •Has a dry body weight of ≥40.0 kg at screening (prescription target dry body weight);
- •Has adequacy of dialysis, defined as meeting 1 of the following criteria during the 3 months prior to screening:
- •≥2 single pool Kt/V measurements ≥1.2; or
- •≥2 urea reduction ratio measurements ≥65%; or
- •1 single pool Kt/V measurement ≥1.2 and 1 urea reduction ratio measurement ≥65%
排除标准
- •A patient will be excluded from the study if any of the following criteria are met:
- •Received an investigational drugwithin 30 days prior to the first dose of study drug, or is planning to participate in another interventional clinical study while enrolled in this study.
- •Has a concomitant disease or any medical condition that, in the opinion of the Investigator, could pose undue risk to the patient, impede completion of the study procedures, or would compromise the validity of the study measurements, including, but not limited to:
- •Known or suspected history of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, -diagnosed alcohol, narcotic or other drug abuse, or substance dependence within 12 months prior to screening;
