About this study
Official title: Therapeutic Impact of Oral Uremic Toxin Absorbent and Probiotics in Chronic Kidney Disease Patients With Peripheral Arterial Disease--- on Gut Microbiota, Circulating Long Noncoding RNA, Metabolome, and Vascular Function
Taiwan has more chronic kidney disease (CKD) per capita than anywhere in the world, leading to the highest expense of National Health Insurance. By reviewing previous studies, uremic toxins contribute critically to the detrimental effects of CKD on atherosclerotic peripheral artery disease (PAD). When recognized early and managed appropriately, mortality and complications of the participants with CKD and established PAD can be minimized. It is critical to identify novel biomarkers and mediators, which can help identify those with potential poor outcomes and facilitate the discovery/development of novel therapeutics for the patients with CKD and PAD. The OMICs studies support the theory that gut microbiome is a major contributor to adverse cardiovascular outcomes and progression of CKD. However, successful integration of multi-omics approach remains sparse. There is no report on the impact of gut microbiota on the host circulating long non-coding RNAs (lncRNAs) expression signature, other CAD/PAD potential marker, and the potential link between gut microbiota, circulating lncRNA levels changes and CKD/PAD. Additionally, although numerous studies indicated that probiotics or activated charcoal have benefits for CKD patients, few studies evaluated the effect of coadministration of activated charcoal/probiotics on the patients with CKD/PAD. The mechanisms of therapeutic effect on CKD/PAD patients with coadministration of activated charcoal/probiotics involving the cross talk among host, microbiota and metabolites still remain unclear. Thus, in the present study, investigators aim to develop novel diagnostic/prognostic markers and a new treatment with activated bamboo charcoal (ABC)/probiotics for therapeutic opportunities to prevent cardiovascular complications, amputation and death in CKD patients with established PAD. To identify the diagnostic/prognostic markers, the multi-omics (microbolome and metabolome) and lncRNA will be analyzed. The therapeutic impact of activated bamboo charcoal (ABC)/probiotics with optimal formulation, on the renal/endothelial/vascular function, cardiovascular (CV) outcome and mortality in CKD patients with PAD will be also determined to evaluate its therapeutic opportunities.

Additionally, the possible mechanisms including the molecular pathway and the roles of microbiota associated with expression profiles of lncRNA and metabolome linked to adverse CV/limb outcome will be investigation. Through combination of innovative molecular biological techniques with new approaches for clinical research, investigators will develop a novel therapy by updated knowledge of the mechanisms of disease and by improved pharmacological technology for the CKD patients with established PAD. Investigators expect to demonstrate the clinical efficacy of ABC ± probiotics to improve symptoms and outcomes of CKD patients with PAD, and offer a possibility to develop a precision medicine with novel diagnostic/prognostic markers and special ABC/probiotic formula, which will ultimately lead to the improved clinical care and outcomes in this population.

What is being measured
The primary outcome is the main question the study is designed to answer.
The change of 6-minute walking distance
The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.
Measured: baseline, 3rd month, 6th month, 1st year, 2nd year and 3rd year
The change of ABI
The ABI value is determined by taking the higher pressure of the 2 arteries at the ankle, divided by the brachial arterial systolic pressure.
Measured: baseline, 3rd month, 6th month, 1st year, 2nd year and 3rd year
The change of vascular duplex
Duplex ultrasound of peripheral artery
Measured: baseline, 3rd month, 6th month, 1st year, 2nd year and 3rd year
The change of serum lncRNA
Long non-coding RNAs (long ncRNAs, lncRNA) are a type of RNA, defined as being transcripts with lengths exceeding 200 nucleotides that are not translated into protein.
Measured: baseline, 3rd month, 6th month, 1st year, 2nd year and 3rd year

Questions about this trial
What is this clinical trial studying?
A study testing Active bamboo charcoal and probiotics in people with CKD and PAD - Peripheral Arterial Disease, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 18 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Chau chung Wu (02-23123456 ext. 88560, Chauchungwu@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The change of 6-minute walking distance (time frame: baseline, 3rd month, 6th month, 1st year, 2nd year and 3rd year). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 18 Jul 2025.
