Efficacy and Safety for Medicurtain® in Prevention of Adhesion After Endoscopic Sinus Surgery (Pivotal Study)
- Conditions
- Tissue Adhesion, Surgery-InducedSinusitis
- Interventions
- Device: GUARDIX-SG®Device: Medicurtain®
- Registration Number
- NCT05049434
- Lead Sponsor
- Shin Poong Pharmaceutical Co. Ltd.
- Brief Summary
This clinical trial is to prove that the treatment group of Medicurtain® is non-inferior to the treatment group of Guardix-sol®, test equipment on adhesion after endoscopic sinus surgery, upon the aspects of adhesion prevention efficacy and safety.
- Detailed Description
This clinical trial was conducted based on multi center, randomized, assessor blind, matched pair design, active-controlled clinical study. After signing consent and fulfilling the standards for selection/exclusion, test subjects went through required treatments following endoscopic surgery; subsequently, according to the order of registration after 2 to 3 days from the surgery, the subjects were applied with a medical device for the clinical test and a medical device for the control test to both of their nasal cavities based on randomization.
For procedures, bleeding was treated and prevented through packing, by soaking Merocel with saline solution following the ESS (Endoscopic sinus surgery) on subjects; and after 2 to 3 days (or upon discharge), it was to treat applied regions of the subjects with assigned medical device after confirming sufficient hemostasis by removing Merocel. Being matched pair active-controlled clinical study, this clinical trial was designed to treat a single subject with both medical devices for clinical test and control test where it was kept unknown which device would be assigned to which nasal cavity based on randomization until the procedure was actually performed. For the time and method of evaluation, observation and evaluation were allowed to be conducted based on the images through endoscopy when subjects visited at 1st, 2nd and 4th weeks following the treatment with medical device. The process of procedure was assured for an identical researcher to perform procedures in order to minimize the effect from the procedure method.
All endoscopic image records of test subjects were delivered by independent assessors, while information on medical device used for treatment was excluded; and independent assessors evaluated each image record according to the evaluation standards prescribed by this clinical trial.
Based on the determination of the researcher during and following the surgery, subjects were administered with 2nd or 3rd generation Cephalosporin Antibiotics. Following the surgery, subjects were instructed to use normal saline solution nasal spray 2 to 3 times a day on both nasal cavities by utilizing bulb-shape tube or syringe. In addition, subjects were also instructed to use intranasal steroid sprays.

- Primary Outcome Measures
Name Time Method Difference between effective ratio (Pt=P00+P01) of medical device for clinical trial and effective ratio (Pc=P00+P10) of medical device for control test evaluated by independent assessor at the 4th week following the application of medical device Week 4 * P00: Ratio of study subjects without adhesion at the application site with medical devices for clinical trial and control test
* P01: Ratio of study subjects without adhesion only at the application site with medical device for clinical trial
* P10: Ratio of study subjects without adhesion only at the application site with medical device for control trial
- Secondary Outcome Measures
Name Time Method Ratio of study subjects without edema and the extent of edema evaluated at each visit follow up to 4weeks Edema is to be score and record at the scale of 0 to 3 points, depending on the extensiveness where the case requiring treatments for edema with steroids shall be scored at 2 points or higher.
\* Standard for grading score of Edema
* Score 0: Mucous membrane edema not visible
* Score 1: Mild mucous membrane edema without extinction of ethmoid sinus
* Score 2: Serious mucous membrane edema with extinction of most ethmoid sinus
* Score 3: Parenchymatous polyposisRatio of study subjects without local infection and extent of local infection evaluated at each visit follow up to 4weeks Infection is to be scored and recorded at the scale of 0 to 2 points where the case requiring treatments for infection shall be scored at 2 points.
\* Standard for grading score of Infection
* Score 0: Proof of infection not visible
* Score 1: Drainage of mild mucopurulent
* Score 2: Drainage of lumpy mucopurulent accompanying parenchymatous infectionPresence of infection requiring treatment evaluated at each visit (Only the cases using antibiotics not for prevention purpose but for treatment purpose) follow up to 4weeks Rate of patient who received 2 or more point in the infection assessment with medical devices for clinical trial or control test.
Presence of adhesion (decomposition or dissolution) requiring treatments at 4th week follow up to 4weeks Rate of patient who received 2 or more point in the adhesion assessment with medical devices for clinical trial or control test.
