Efficacy and Safety of the Ultrasound Stimulation Device NEFRONIX in Patients With Chronic Kidney Disease

Sponsor: Anasonic

View on ClinicalTrials.gov

Summary

This study is a prospective, multicenter, single-arm, open-label, non-randomized exploratory clinical trial designed to evaluate the safety and potential efficacy of an ultrasound stimulation device (NEFRONIX G-01) in patients with chronic kidney disease (CKD). Baseline functional assessments will be performed prior to intervention. Participants will receive ultrasound stimulation applied to the kidneys three times per week for four weeks according to the study protocol. Clinical evaluations will be conducted at baseline, at the end of treatment, and 12 weeks after completion of treatment. Renal function will be assessed using changes in estimated glomerular filtration rate based on serum creatinine (CKD-EPI eGFR Cr) and cystatin C (CKD-EPI eGFR CysC). Additional assessments will include imaging studies (Tc-99m DTPA renal scintigraphy and renal ultrasonography), urinalysis for proteinuria, inflammatory markers (high-sensitivity C-reactive protein), and renal injury biomarkers (neutrophil gelatinase-associated lipocalin).

DEVICE

Ultrasound Stimulation (NEFRONIX G-01)

Ultrasound stimulation will be delivered to the renal area using the NEFRONIX G-01 device. The intervention will be administered three times per week for four weeks in accordance with the study protocol. Standard clinical management for chronic kidney disease will be continued during the study period.

Inclusion Criteria: * Participants who have received sufficient explanation of the study and have voluntarily provided written informed consent. * Male and female adults aged 18 to 65 years at the time of consent. * Participants with chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) between 20 and 60 mL/min/1.73 m². * Participants who agree to use and maintain appropriate contraception throughout the study period. Exclusion Criteria: * Participants currently enrolled in another clinical study with an ongoing follow-up period. * Participants with heart failure. * Participants who have undergone reperfusion therapy for cardiovascular disease within the past year. * Participants with platelet or coagulation disorders, including those receiving antithrombotic therapy. * Participants with acute or chronic urinary tract infection. * Participants with polycystic kidneys. * Participants with anatomical kidney abnormalities (e.g., solitary kidney, horseshoe kidney, polycystic kidney disease) as determined by the investigator. * Participants with urinary tract obstruction. * Participants who have received a kidney transplant. * Participants with kidney or urinary tract stones. * Participants who have experienced acute kidney injury or changes in CKD stage within the past 3 months. * Participants with serum albumin \<3.0 g/dL and either 24-hour proteinuria ≥3.0 g/day or random urine protein/creatinine ratio ≥3.0 mg/mg. * Participants with uncontrolled hypertension (systolic blood pressure \>150 mmHg or diastolic blood pressure \>100 mmHg despite treatment with two or more antihypertensive medications). * Participants with liver dysfunction. * Participants receiving immunosuppressive therapy. * Participants with body mass index (BMI) \>35 kg/m² or body weight \<40 kg. * Participants with a history of severe illness, such as cancer or tuberculosis. * Participants with contact dermatitis or other significant skin sensitivities. * Participants with fever ≥40°C (104°F) measured via tympanic temperature. * Participants deemed unsuitable for participation in the study by the investigator for any other reason.
