Not Applicable

Recruiting

• Conditions: Osteoarthritis

• Registration Number: NCT06207851
• Lead Sponsor: Next Biomedical Co., Ltd.

Brief Summary

In patients with chronic elbow or wrist pain, the pain is controlled by conventional conservative therapy The pain reduction effect of Nexsphere-F embolization in patients who need additional treatment It is intended to demonstrate safety.

Detailed Description

This clinical trial is a single cancer, single center, open label, and pilot clinical trial that demonstrates the performance and safety of Nexsphere-F for patients aged 19 to 80 who need additional treatment because their pain is not controlled even after taking existing treatments.

In addition, through this clinical trial, complications of embolization and Nexsphere-F and It checks the safety of side effects. Therefore, in this study, TAME treatment for patients with chronic elbow pain 2 to 7 months, 1 month later, 3 months, 6 wah VAS score reductions and QuickDASH scores, PRTEE score primary 6 Evaluate the reduction rate of medication, discontinuation rate of combination therapy, and occurrence of abnormal cases during the follow-up period. For patients with chronic wrist pain, VAS score after 2 to 7 days, 1 month, 3 months, and 6 months of TAME treatment QuickDASH score reduction rate, drug reduction rate after 6 months, discontinuation rate of combination therapy, and follow-up period the investigators will evaluate the effectiveness and safety of Nexsphere-F by evaluating whether abnormal cases occur during the period.

Arm && Interventions

Group	Intervention	Description
Experimental	Transcatheter Arterial Micro-Embolization	If abnormal blood vessels related to pain are identified by angiography, selective embolization is performed using Nexsphere-F.

Primary Outcome Measures

Name	Time	Method
Rate of subjects with a 50% or more reduction in QuickDASH Score Change	2~7days,1 month, 3 months, 6 months	Descriptive statistics (mean, standard deviation, median, minimum and maximum) are presented for each visit compared to the average change rate baseline of the QuickDASH score before and after clinical trial medical device application.

Secondary Outcome Measures

Name	Time	Method
Rate of VAS Score (patient pain intensity) Change	2~7days,1 month, 3 months, 6 months	The rate of change of VAS Score (patient pain intensity)Score before and after application of medical devices for clinical trials.(The visual analog scale(VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain." (10). The ends are defined as the extreme limits of the parameter to be measured(symptom,pain,health) orientated from the left(0, worst) to the right(10, best).)
The rate of reduction of medication	6 months	The rate of change of medication before and after application of medical devices for clinical trials.
Rate of Changes in symptoms according to in QuickDASH Score	2~7days,1 month, 3 months, 6 months	The rate of change of QuickDASH Score before and after application of medical devices for clinical trials.(Change in Patient-Reported Function as measured by the short form Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaires. QuickDASH scores range from 0 (no disability) to 100 (most severe disability.))
Rate of Changes in symptoms according to the Patient-Rated Tennis Elbow Evaluation (PRTEE) Score	2~7days,1 month, 3 months, 6 months	The rate of change of Patient-Rated Tennis Elbow Evaluation (PRTEE) Score before and after application of medical devices for clinical trials.((Measurements the patient functional status its 15 questionnaires In PRTEE First subscale is The Pain Subscale detail is 5 items Maximum or best score is 0 and worst score is 50 The Second Subscale or PRTEE is The Specific Activities detail is 6 items with finest score is 0 and least score is 60 The third one subscale of PRTEE the Usual Activities sub part 4 items with superior score is 0 and least score is 40. Third Fourth Part of PRTEE is The Function Subscale detail is performance bases specific activities and usual or regular activities Add up to specific or regular activities divided by 2 Maximum best score or prime score is 0 and least score is 50 Total detail Score of PRTEE is = Pain Subscale + Function Subscale Best Score= 0 Worst Score = 100 (pain and disability contribute equally to score).)
