Safety and Effectiveness of the Peregrine Drivable ENT Scope for Endoscopy of the Paranasal Sinuses

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the safety and effectiveness of the Peregrine endoscope in patients in the office setting in terms of access into and visualization of the paranasal sinus anatomy, image quality, patient tolerability and clinical utility. Up to 30 participants who have had prior endoscopic sinus surgery (ESS) and are scheduled for nasal endoscopy in the office as part of a routine post-operative office visit or due to recurrence of symptoms, will be evaluated with the Peregrine Endoscope as well as a standard endoscope. This study aims to: compare visualization success rates of the paranasal sinus anatomy by Peregrine and by a standard endoscope used in the office setting. examine device related adverse events. assess the adequacy of the image quality of Peregrine for endoscopy procedures in the office. evaluate patient tolerability and pain

Detailed Description
-----------------
Nasal endoscopy is a minimally invasive, diagnostic medical procedure and currently the most preferred initial method of evaluating medical problems affecting nose and sinuses such as nasal stuffiness and obstruction, sinusitis, nasal polyposis, nasal tumors, epistaxis, recurrent bouts of sneezing and rhinorrhea. Overall, the procedure is considered very safe and low-risk. Currently, nasal endoscopy can be performed with a flexible or rigid endoscope, typically after a topical decongestant and anesthetic are applied to the nasal mucosa. Reprocessing is an issue of concern, especially for flexible endoscopes where multiple steps were confirmed to be critical for reprocessing to be effective. High-level disinfection has been determined to be the minimum level of disinfection required, which involves multiple steps including manual cleaning, leak testing, cleaning with an enzymatic agent, high-level disinfection, and drying with vertical storage. 3NT Medical Ltd. has developed the Peregrine Drivable Ear Nose and Throat (ENT) Scope, which offers the convenience of a single-use endoscope component coupled with performance characteristics of commercially available state-of-the-art reusable endoscopy systems. The single-use endoscope essentially removes concerns related to burdensome reprocessing techniques of a delicate tool required to achieve high-level of its disinfection. The objective of this study is to assess the safety and performance of the Peregrine endoscope in patients in the office setting in terms of access and visualization of the paranasal sinus anatomy, image quality, and patient tolerability and pain. For this study, up to 30 patients who have had prior endoscopic sinus surgery (ESS) and who are scheduled for nasal endoscopy in the office, as part of a routine post-operative office visit or due to recurrence of symptoms, will be evaluated with Peregrine Endoscope. Access and visualization by an additional standard endoscope will be conducted and compared to Peregrine endoscope. Image quality of the Peregrine endoscope, participant tolerability and pain, and the impact of Peregrine on clinical decision making will be evaluated.

Design Details

Primary Purpose: Diagnostic
Intervention Model: Single Group Assignment
Interventional Model Description: Patients who have had prior ESS and are scheduled for nasal endoscopy as part of a routine post-operative office visit or due to recurrence of symptoms will be evaluated with the standard endoscope followed by the Peregrine Endoscope.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Standard 30° 4mm Endoscope Followed by Peregrine Endoscope<br>Participants will receive an endoscopy with the standard 30° 4mm endoscope followed by an endoscopy with the Peregrine Drivable ENT Scope. | Device: Peregrine Drivable ENT Scope<br>* Peregrine, developed by 3NT Medical, is a single-use disposable handheld endoscope, which is thinner and more flexible than other endoscopes. The endoscope includes a camera at its end and a working channel. The thin endoscope provides a means to visualize the nasal cavity and paranasal sinus space and to deliver irrigation to treat the sinus ostia (drainage openings) and spaces within the paranasal sinus cavities<br>Device: Standard 30° 4mm Endoscope<br>* The Standard 30° 4mm endoscopic sinus evaluation is the standard procedure that would normally be used to evaluate the condition of each participant.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Visualization Success of Maxillary Sinus Anatomy | The ability of each endoscope type to visualize the maxillary sinus anatomy (ostium, floor, lateral recess, anterior wall) was assessed as being a success or failure. | Day 1 (after each endoscopy) | 
| Number of Participants With Visualization Success of Frontal Sinus Anatomy | The ability of each endoscope type to visualize the frontal sinus anatomy (ostium, posterior table, anterior table, lateral recess) was assessed as being a success or failure. | Day 1 (after each endoscopy) | 
| Number of Participants With Visualization Success of Sphenoid Sinus Anatomy | The ability of each endoscope type to visualize the sphenoid sinus anatomy (ostium, sella, floor, lateral aspect) was assessed as being a success or failure. | Day 1 (after each endoscopy) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adequate or Inadequate Image Quality From Peregrine Endoscopy | Image quality will be assessed through a yes/no statement, reported by physicians, regarding the adequacy of the Peregrine image quality for making clinical decisions in the office setting. | Day 1 (after each endoscopy) | 
| Visual Analogue Scale (VAS) Tolerability Score | Participant tolerability was evaluated through validated VAS for both endoscopies. Scores range from 1 to 10, where 1 = highly tolerable and 10 = not tolerable. | Day 1 (after each endoscopy) | 
| VAS Pain Score | Participant pain was evaluated through validated VAS for both endoscopies. Scores range from 1 to 10, where 1 = no pain and 10 = pain as bad as it could be. | Day 1 (after each endoscopy) | 
| Impact on Clinical Workflow | The impact on clinical workflow of visual information obtained by each endoscope procedures was rated by physicians on a 5-point scale where 1 = worst and 5 = best. | Day 1 (after each endoscopy) | 
| Ease of Use | The ease of use of each endoscope procedure was rated by physicians on a 5-point scale where 1 = worst and 5 = best. | Day 1 (after each endoscopy) |
