CPU: Intel Core i3 2.0GHz or later GPU:rtx4000 or later Monitor: Resolution 1920*1080 or higher HDD: 250GB or above Memory: 8GB or above USB Port: 2 or more Operating System: Windows 7 or above 1.3 Summary of Clinical Performance The NaviCam Small Bowel Capsule Endoscopy System was evaluated in two clinical studies: (1) a prospective study, comparing its performance to that of the FDA cleared PillCam SB3 Capsule Endoscopy System (hereafter referred to as PillCam SB System); and (2) a retrospective study to evaluate the performance of the optional ProScan feature of the ESView software. Summaries of both studies are provided below, and the full reports are attached to Section 20.

(1) Performance Evaluation of the AKE-1(NaviCam SB) Capsule Endoscope System in Comparison to the PillCam SB3 Capsule System for the Diagnosis of Small Bowel Diseases This was a prospective, comparative study in 3 sites in China, aimed to evaluate the performance of the NaviCam SB System (trial capsule) when compared to the PillCam SB System (control ANKON Technologies Co., Ltd. AKQWO-YF-018 Rev A/1 NaviCam Small Bowel Capsule Endoscopy System User Manual P a g e | 11 capsule or comparator) for the diagnosis of small bowel diseases. Study primary endpoints included Per Findings analysis, where the recordings obtained with both capsules were independently evaluated and the agreement between findings of both capsules was evaluated; and, Per Subject analysis; where the diagnosis of subjects based on independent interpretation of images obtained with both capsules was evaluated (diagnosis of normal or abnormal per subject). A number of secondary endpoints were also assessed including ease of swallowing the capsule, intestinal transit time, capsule excretion time, diagnostic yield when compared to other standard mucosal imaging procedures, quality of small bowel images, image reading time, and agreement between two or more reviewers with respect to interpretation of the images obtained. The study included adult subjects with symptoms of small bowel diseases or suspected gastrointestinal bleeding. After signing informed consent, subjects who met the study eligibility criteria completed gastrointestinal preparation in advance according to the examination schedule. Before swallowing the capsules, an antifoaming agent (10ml simethicone) with 120ml of water was administered to reduce air bubble formation in the small bowel. Each subject wore the two types of data recorders then swallowed the two types of small bowel capsules approximately 40 minutes apart in a randomized order. Subjects were allowed to drink water 2 hours after swallowing the capsules and eat a small amount of food 4 hours after swallowing the capsules. Upon confirming that the capsules have entered the small bowel, the subjects left the hospital and were instructed to continue wearing the data recorders for 8-10 hours until the power of the capsules were depleted, or the capsules were excreted. The anonymized images acquired by both the trial capsule and comparator were read by two gastroenterologists independently for normal and abnormal interpretation and analysis of lesion type (edema, polyp, hemorrhage, etc.), capsule transit time, reading time and image quality; in cases of disagreement, a third gastroenterologist reviewed the video in question and provided his/her result. A total of 97 subjects were enrolled in the study; 10 subjects were withdrawn or withdrew consent prior to the study procedure. As these subjects did not swallow the capsules, they were excluded from data analysis, therefore, the results from 87 subjects were included in both Per Protocol Set (PPS) analysis and Full Analysis Set (FAS).

One case of capsule retention occurred where both NaviCam and PillCam capsules were retained. The incidence of adverse events was 1.15%. No abdominal pain, abdominal distention, nausea, vomiting, headache, obstruction, or other adverse events occurred. In conclusion, the NaviCam SB System and PillCam SB System had a diagnostic overall percent agreement rate of 89.66% (81.50%, 94.46%), and an overall percent agreement Kappa of 0.6652

(0.4653, 0.8652). The results of this comparative study indicate that NaviCam Small Bowel Capsule Endoscopy System performs similarly to the PillCam SB3 Capsule Endoscopy System and provides an effective non-invasive method for the detection of small bowel diseases.

(2) Retrospective Evaluation to Compare Small Bowel Video Reading by AKE-1 (NaviCam SB) Capsule Endoscopy System with ProScan Feature and PillCam SB3 Capsule System with SBI Feature The goal of this retrospective evaluation was to compare the performance of the NaviCam SB System ESView software with the ProScan feature to this of the PillCam SB System with the SBI feature. The recordings/images used in this study were previously obtained in the prospective study (study (1)) and were analyzed by two independent reviewers for visual comparison of the findings and analysis using ESView software with ProScan and Rapid software with SBI in comparison to the conventional reading previously performed for both systems. Capsule endoscopy videos of 87 subjects were used and included in both the Full Analysis Set

(FAS) and Per Protocol Set (PPS) analyses. The primary endpoint of the study was to evaluate the performance of the NaviCam SB System with the ProScan software feature in comparison with the PillCam SB System SBI feature (per patient analysis). Secondary study endpoints included per findings analysis, image review time, and image review time of NaviCam reading with and without the ProScan feature on. ANKON Technologies Co., Ltd.

McNemar Test Results These results demonstrate that the NaviCam SB System and PillCam SB System have good diagnostic consistency. There were no statistically significant differences in the diagnosis of vascular lesions (p=0.4497), inflammatory lesions (p=0.3173, tumors/polyps/masses (p=0.2207), malabsorption (p=1.0000), ulcers/ulcerations (p=0.7963), and other lesions (p=0.0863) between the NaviCam SB and PillCam SB systems. The video review time of the trial capsule was 1.63 min higher than that of the control capsule, and the difference was statistically significant. The difference between the mean reading time of the NaviCam SB with ProScan on and conventional reading (i.e., without ProScan feature on) was

-36.63 min (-46.29 min, -26.72 min) (95% CI), the difference was statistically significant. The results of the analysis of the consistency of the interpretation of the images obtained by two or more reviewers (FAS/PPS) show that the differences between the two groups are not statistically significant. The results of this study showed that the clinical performance of the NaviCam SB System with the ProScan feature and PillCam SB System (with SBI) were similar, and that the NaviCam SB System with ProScan feature on significantly reduced the physician's reading time compared to the reading time of the NaviCam SB System without the ProScan on (21.478.05 vs. 58.1045.28, p<0.0001). ANKON Technologies Co., Ltd. AKQWO-YF-018 Rev A/1 NaviCam Small Bowel Capsule Endoscopy System User Manual P a g e | 14 CHAPTER 2: INDICATIONS, CONTRAINDICATIONS AND WARNINGS 2.1 Indications The NaviCam Small Bowel Capsule Endoscopy System is intended for visualization of the small bowel mucosa in adults. It may be used as a tool in the detection of abnormalities of the small bowel. 2.2 Contraindications The capsules are contraindicated for use under the following conditions:

In patients with known or suspected gastrointestinal obstruction, strictures, or fistulas based on the clinical picture or pre-procedure testing and profile. In patients with cardiac pacemakers or other implantable electronic medical device. In patients with an easily magnetized metal part. In patients with dysphagia or other swallowing disorders. In pregnant women. Note: The Capsule maybe deployed by using transendoscopic delivery in patients who are unable to ingest the capsule or are known to have prolonged gastric emptying time. Placement into the duodenum is recommended to prevent the patient from vomiting the capsule. Potential adverse events associated with the use of a capsule include injury to a patient caused by delayed excreting or not excreting of capsule, aspiration of the capsule, and interference from strong magnetic field sources. It could be necessary to remove the capsule by intervention. 2.3 Adverse Events 2.4 Warnings A negative or normal result obtained by the capsule does not exclude the presence of pathology and if symptoms persist, further evaluation should be performed. If intestinal fistulas, strictures, or stenosis are suspected, or the patient has had prior abdominal or pelvic surgery, the physician should consider performing an examination to ascertain patency for an object the size of the capsule. The safety of the capsule has not been established in children. The capsule should not be swallowed by patients where a concern for aspiration of the capsule exists (e.g., due to cognitive or neurological deficits or a history of aspiration). In these patients, it is recommended that a capsule endoscopic delivery system be used to ANKON Technologies Co., Ltd. AKQWO-YF-018 Rev A/1 NaviCam Small Bowel Capsule Endoscopy System User Manual P a g e | 15 place the capsule directly in the duodenum. Placement of the capsule in the duodenum will decrease the risk of aspiration of the device [by vomiting] and gastric retention. A thorough understanding of the technical principles, clinical applications and risks associated with the Capsule System is necessary before using this product. Read the entire manual before using the system for the first time. Make sure that only trained personnel or professional personnel, familiar with all operating procedures of the NaviCam SB System, use the system. To prevent the patient from being exposed to unforeseen risks during passage of any capsule, make sure the patient thoroughly understands the procedure, and provide the patient with a copy of the Patient Labeling. A patient with known or suspected delayed gastric emptying (whether disease related or drug induced) could be at increased risk for incomplete the NaviCam SB System. When swallowing the capsule there is a possibility of choking on the capsule. If the patient exhibits any symptoms and/or clinical signs of choking (labored breathing, wheezing, involuntary coughing, etc.), the recommended first-aid procedure should be followed. Keep the capsule away from implants such as pacemakers and other devices that could be affected by proximity to a DC magnetic field. If a child has accidentally swallowed any unused or spent capsule, seek medical attention. Instruct the patient not to sit on bare metal surfaces, such as chairs with metal seating area, during the procedure. Instruct the patient to contact the physician immediately if, after ingesting any capsule, there is any abdominal pain, nausea, or vomiting. Only one capsule should be ingested at a time and only after confirmation that no other capsules or ingestible diagnostic devices remain in the patients body. If, contrary to instructions, a patient ingests more than one capsule, instruct the patient to immediately contact the physician. In patients with unsuspected strictures of the GI tract, any capsule can potentially cause intestinal obstruction resulting in the need for hospitalization and surgery. The safety of this device in patients with significant gastrointestinal diverticular disease is unknown. Final diagnosis based on the capsule images should be made only by physicians who are trained in the interpretation of capsule endoscopy images. If there is reasonable doubt concerning the integrity of the capsule due to dropping, biting, or any other eventuality, the capsule should be deactivated by returning it to its box and it should not be used until consulting with an authorized ANKON Technologies representative. Store all capsules in a safe place, out of the reach of children and infants. Do not use any capsule after its expiration date. Instruct the patient to avoid biting the capsule prior to swallowing. Instruct the patient to wear the data recorder throughout the procedure. After ingesting the capsule and until it is excreted, the patient should not be near any source of powerful electromagnetic fields such as one created near an MRI device. ANKON Technologies Co., Ltd. AKQWO-YF-018 Rev A/1 NaviCam Small Bowel Capsule Endoscopy System User Manual P a g e | 16 Undergoing an MRI while the capsule is inside the patient's body may result in serious damage to his/her intestinal tract or abdominal cavity. If the patient did not positively verify the excretion of any capsule from his/her body, he/she should contact the physician for evaluation with the Locator and possible abdominal X-ray before undergoing an MRI examination. A capsule should be ingested only in the presence of authorized medical personnel. The patient should be instructed not to let relatives, neighbors or acquaintances use any capsule without medical attention. If excretion of the capsule from the patient has not been positively verified, and the patient develops unexplained post-procedure abdominal pain, vomiting, or other symptoms of obstruction, he/she should contact the physician for evaluation with the Locator and possible abdominal X-ray examination. Use the system only with components purchased from ANKON Technologies. Use of other components may damage the system and void the warranty. In a small number of cases, the capsules may not image the entire small bowel due to variations in patient GI motility. After ingesting the capsule, the patient should abstain from eating or drinking for another 2 hours. After 2 hours, the patient may drink water. After 4 hours, the patient may have a light snack. After the examination is completed, the patient may return to a normal diet. These instructions related to eating apply unless physician instructs otherwise. The inspection will last for about 8 hours. The physician should instruct the patient when the examination is considered complete. During the examination, the patient should avoid any physical activity that involves sweating and to abstain from bending. The Data Recorder should be treated with utmost care and protection. Sudden movement and banging of the Data Recorder should be avoided. The patient should be instructed not to remove the Data Recorder during the examination.
