Epitomee is indicated to aid in weight management in overweight and obese adults with a Body Mass Index (BMI) of 25 - 40 kg/m², when used in conjunction with diet and exercise.
The subject device of this 510(k) notification, Epitomee, is comprised of two components: The outer component is a capsule and the inner component contains superabsorbent hydrogel particles. Each particle is approximately 250 microns in size. The particles are enclosed in pH sensitive compartments. Once Epitomee is swallowed, the capsule disintegrates in the stomach and releases the pH sensitive compartments. By absorption of water in the stomach fluid, the superabsorbent particles within the compartments swell to form a three-dimensional matrix designed to occupy volume in the stomach that creates a sensation of fullness, enabling weight loss. Epitomee mechanism of action is purely mechanical and does not involve any chemical activity. Epitomee works directly in the gastrointestinal (GI) tract. Epitomee is provided non-sterile.
The provided document is a 510(k) summary for the device "Epitomee," which is an ingested, transient, space-occupying device for weight management. The document describes the device, its intended use, and the performance data that supports its substantial equivalence to a predicate device.
However, the document does not contain specific acceptance criteria or an explicit study proving that the device meets those acceptance criteria in the format requested by the prompt. Instead, it discusses the outcomes of clinical studies (RESET and ELECT) in comparison to a placebo or to demonstrate continued safety and efficacy. It focuses on demonstrating substantial equivalence to a predicate device (Gelesis Inc.'s Plenity) rather than meeting predefined, quantitative acceptance criteria for a new, novel device.
The prompt specifically asks for a table of acceptance criteria and reported device performance, sample sizes, expert qualifications for ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for training and test sets. This information is typically found in detailed study reports or regulatory submissions for devices that require proof of meeting specific performance endpoints, especially for software or AI/ML-based devices. Epitomee is a physical medical device, not a software or AI/ML device in the conventional sense that would require the rigorous performance evaluation methods listed in the prompt (e.g., ground truth established by experts, MRMC studies, standalone algorithm performance).
Therefore, based on the provided text, I cannot extract the specific information requested in your prompt regarding acceptance criteria and the study proving the device meets them, because such a section or study design (as understood in the context of AI/ML or software device evaluation) is not present. The document describes a clinical trial (RESET study) demonstrating efficacy and safety compared to a placebo, and an extended study (ELECT) for long-term safety, to support "substantial equivalence" to a predicate device.
To answer your prompt, I must state that the detailed information about "acceptance criteria" and a "study that proves the device meets the acceptance criteria" in the format requested (especially points 1, 3, 4, 5, 6, 7, 8, 9) is NOT available in the provided 510(k) summary. The document's purpose is to demonstrate substantial equivalence, which relies on showing similar intended use, technological characteristics, and comparable safety and effectiveness, often through non-inferiority or superiority trials against a placebo/standard of care, rather than meeting pre-specified quantitative performance metrics for a diagnostic or AI system.
I can, however, provide the closest relevant information from the document that might relate to "performance" and "study outcomes" as a proxy, but it will not directly answer your prompt's specific requirements.
Closest Related Information from the Provided Document:
The document describes the Pivotal Clinical Study (RESET Study) as the primary evidence for the device's performance.
1. A table of acceptance criteria and the reported device performance:
The document does not provide a formal table of "acceptance criteria" for its performance as would be expected for a diagnostic or AI device. Instead, it states that "both co-primary endpoints were successfully met." These endpoints function as the 'criteria' for success.
| Metric / Endpoint | Acceptance Criteria (Met/Achieved) | Reported Device Performance (Epitomee Group) | Control Group (Placebo) Performance | Statistical Significance |
|---|---|---|---|---|
| Co-primary Endpoint 1: | Significant reduction in total body weight (TBW) compared to placebo at 24 weeks. | Mean TBW reduction: 6.6% (SD 6.5) | Mean TBW reduction: 4.6% (SD 4.7) | P<0.0001 |
| Co-primary Endpoint 2: | Rate of subjects with ≥5% TBW reduction at 24 weeks significantly exceeding a threshold. | 55.5% (CI: 46.1-64.6) of subjects achieved ≥5% TBW reduction | (Not explicitly stated for placebo in this context, but implies lower) | P<0.0001 (>35% threshold met) |
| Secondary Endpoint: | Higher percentage of responders losing between 7.5-12.5% of TBW compared to placebo. | ≥ 7.5% TBW loss: 38.7% ≥ 10% TBW loss: 26.9% ≥ 12.5% TBW loss: 16.8% | ≥ 7.5% TBW loss: 21.5% ≥ 10% TBW loss: 10.7% ≥ 12.5% TBW loss: 6.6% | Implied significance (stated "significantly higher percentage") |
| Safety: | Favorable safety profile, low incidence of adverse events, no serious adverse device effects (SADEs). | Fewer patient dropouts (13.8%) No SADEs Overall incidence of treatment-emergent AEs similar to placebo (mild/moderate for >95%) No difference in gastrointestinal AEs. | Patient dropouts (14.2%) | Met |
2. Sample size used for the test set and the data provenance:
- Test Set Sample Size: The "test set" in this context refers to the subjects enrolled in the clinical trial.
- Total Enrolled: 279 men and non-pregnant, non-lactating women.
- Epitomee Group: 138 subjects (13.8% dropouts, so ~119 completed)
- Placebo Group: 141 subjects (14.2% dropouts, so ~121 completed)
- Data Provenance:
- Country of Origin: All 9 study sites were in the US, located across 9 different states.
- Retrospective or Prospective: Prospective, randomized, double-blind, placebo-controlled, multicenter trial.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not applicable and not provided. "Ground truth" established by experts is typically for diagnostic interpretation (e.g., radiologist reads). For a weight management device, the "ground truth" for efficacy is objective clinical measurements (body weight, BMI) and for safety, it's reported adverse events and monitoring by investigators.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This is not applicable and not provided. Adjudication methods are typically used for interpreting diagnostic images or clinical events by multiple readers/experts. For a device like Epitomee, efficacy is measured directly (weight change), and safety is based on adverse event reporting by subjects and assessment by clinical investigators, not adjudicated panel reviews for "ground truth".
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- This is not applicable. MRMC studies are specific to evaluating AI/software performance in diagnostic tasks by comparing human reader performance with and without AI assistance. Epitomee is a physical device, not an AI or diagnostic software.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- This is not applicable. Standalone performance refers to the performance of an algorithm or software system without human interaction. Epitomee is a physical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for efficacy was objective outcomes data (measured Total Body Weight reduction, percentage of subjects achieving specific weight loss thresholds, BMI reduction, improvements in quality of life scores).
- The "ground truth" for safety was adverse event reporting by subjects and assessment by the investigational site staff (physicians, nurses).
8. The sample size for the training set:
- This information is not provided because Epitomee is a physical device, not an AI/ML model that requires a "training set." Device development typically involves bench testing, non-clinical studies (e.g., animal studies), and clinical trials, not "training" in the AI sense.
9. How the ground truth for the training set was established:
- This is not applicable as there is no "training set" in the context of an AI/ML model for this physical device.

Epitomee Medical's Epitomee
Submitter
Epitomee Medical Ltd. 17 Hatochen St. Caesarea lsrael
Contact Person: Ruthie Amir Date Prepared: September 12, 2024
Name of Device: Epitomee
Common Name: Weight management device
Regulation Number: 21 CFR 876.5982
Classification Name: Ingested, transient, space occupying device for weight management and/or weight loss
Product Code: QFQ
Regulatory Class: II
Predicate Device: Gelesis Inc.'s Plenity (DEN180060)
Device Description
The subject device of this 510(k) notification, Epitomee, is comprised of two components: The outer component is a capsule and the inner component contains superabsorbent hydrogel particles. Each particle is approximately 250 microns in size. The particles are enclosed in pH sensitive compartments. Once Epitomee is swallowed, the capsule disintegrates in the stomach and releases the pH sensitive compartments. By absorption of water in the stomach fluid, the superabsorbent particles within the compartments swell to form a three-dimensional matrix designed to occupy volume in the stomach that creates a sensation of fullness, enabling weight loss. Epitomee mechanism of action is purely mechanical and does not involve any chemical activity. Epitomee works directly in the gastrointestinal (GI) tract. Epitomee is provided non-sterile.
Intended Use / Indications for Use
Epitomee is intended to aid in weight management in overweight and obese adults with a Body Mass Index (BMI) of 25 - 40 kg/m², when used in conjunction with diet and exercise.
{5}------------------------------------------------
Summary of Technological Characteristics
Epitomee has very similar technological characteristics compared to the predicate device. Both devices are composed of two major components: an outer capsule and an inner expendable component occupying space in the stomach. Both devices are ingestible, transient, space occupying devices designed as a standard capsule for oral intake. For both devices the oral capsule encloses self-expandable particles that form a three-dimensional matrix designed to occupy volume in the stomach, to create a sensation of fullness. The capsule of both devices disintegrates in the stomach and releases the enclosed self-expanded particles. For both devices the hydrogel particles increase their weight and dimensions after absorbing water from the stomach and both devices interact with the stomach by occupving volume. Both devices are self-disintegrated to enable natural evacuation through gastric emptying.
Although the subject device consists of a triangular arrangement and has a smaller net volume than the predicate, the triangular shape of the compartments was designed to attain relatively large dimensions, creating a space occupying tree-dimensional structure and the difference does not raise new questions of safety or effectiveness as both devices achieve their intended use by occupying volume in the stomach, thereby creating sensation of fullness. Clinical study results showed that the subject device is as safe and effective as the predicate device. In addition, despite the different materials used by the two devices utilize hydrogel materials to expand with water. Both devices have been demonstrated to be biocompatible. Furthermore, both devices are intended to degrade within the user's GI tract and be eliminated through normal bowel movements emptying.
A table comparing the key features of the subject and predicate device is provided below.

Clinical Data
The performance of Epitomee is supported by multiple clinical studies.
Pivotal Clinical Study (RESET Study)
The RESET study was a prospective, randomized, double-blind, placebo-controlled, multicenter trial to support the use of Epitomee for weight reductions in patients. The study enrolled 279 men and non-pregnant, non-lactating women, 18 years of age or older, who are overweight (body mass index [BMI] of 25-30 kg/m²) or obese (BMI of 30-40 kg/m²), with and without prediabetes. All 9 sites enrolled in the study were in the US, located across 9 different states.
The subjects were evenly matched for gender and age groups with females constituting 80.4% and 79.4% of the Epitomee and placebo groups, respectively, and the majority of subjects being between 40 and 65 years of age (66.7% and 67.4% in the Epitomee and placebo groups, respectively). Mean BMI was 34.1 in Epitomee group and 33.7 in the placebo group. The majority of the study subjects were Caucasian, with 70.3% and 65.2% of the recruited in the Epitomee and placebo groups, respectively. Black or African American subjects constituted 21.0% and 24.1% of the total sample in the Epitomee and placebo groups, respectively.
Eligible subjects were randomized to test or placebo arms. Subjects were to take one capsule of the investigational device or placebo twice daily, with 2 cups of water half-hour before the main meals, for 24 weeks. Subjects in both groups received the same program of diet, physical activity, and behavior therapy. Efficacy and safety assessments were conducted up to week 24 since start of the study treatment. An additional safety assessment was conducted at week 28.
{10}------------------------------------------------
The study demonstrated that both co-primary endpoints were successfully met. Epitomee treatment group total body weight (TBW) reduction at 24-weeks post randomization was significantly greater (mean, 6.6%; SD, 6.5) than the placebo group (mean, 4.6%; SD, 4.7) (P<0.0001). The co-primary endpoint of treatment responders was also achieved: the rate of Epitomee treatment group subjects whose total body weight was reduced by at least 5% at 24-weeks post randomization was 55.5% (Cl: 46.1-64.6), significantly exceeding the threshold of >35% (P<0.0001).
Subgroup analyses were performed to evaluate total body weight loss at week 24 in clinically relevant subgroups of patients (gender, baseline BMI categories, subjects with %TBW≥0) and showed higher TBW reduction in the Epitomee arm than the placebo arm. The differences between the arms ranged from approximately 2%-5%.
Epitomee capsule treatment efficacy is further supported by the analysis of seconday endpoints. Epitomee capsule treatment resulted in a significantly higher percentage of responders losing between 7.5-12.5% of TBW as compared to the placebo treatment. Specifically, 38.7% of Epitomee treated patients achieved ≥ 7.5%, 26.9% achieved ≥ 10%, and, 16.8%, ≥ 12.5% of TBW loss compared to 21.5%, 10.7% and 6.6% in the placebo group. Consistent with the weight results, Epitomee treatment achieved a greater reduction in Excess Weight Loss (EWL) and higher BMI reduction over time resulting in more subjects shifting from obesity Class II to a lower obesity category.
Finally, subjects treated with Epitomee showed better improvement in quality of life in several items of the IWQOL-Lite-CT questionnaire as well as the physical function relative to the placebo group, with physical function score being statistically meaningful and both physical score and total score being marqinally significance.
The study demonstrated a favorable safety profile of Epitomee treatment throughout the study duration. Epitomee treatment was well tolerated, with fewer patient dropouts in Epitomee group than the control group 19 (13.8%) and 20 (14.2%), respectively. There were no serious adverse device effects (SADEs) in the study.
There were no differences in the incidence of treatment-emergent AEs between the study groups. Adverse events were equally distributed between the groups when assessed by severity. There were no differences in the incidence of treatment-emergent AEs between the groups in relation to causality, AE outcome, and action taken. In both groups, almost all adverse events were assessed by the investigator as mild or moderate in intensity (>95%). The overall incidence of treatment-emergent gastrointestinal adverse events was no different in the Epitomee group vs. the control group.
Notably, the safety and efficacy performance of Epitomee as shown in the RESET study was very similar to that of the predicate device.
Extended Study (ELECT Study)
The ELECT study assessed the effect of Epitomee on body weight after an additional exposure of 24 weeks in subjects from the RESET pivotal study. Subjects from Epitomee and Placebo
{11}------------------------------------------------
groups in the RESET study who completed the 24-week treatment period and had at least 3% weight loss were offered to participate in this extended study. The ELECT study is an openlabel, one arm extension study and all subjects were treated with Epitomee, twice daily. Sixteen (16) subjects who were assigned to the placebo during RESET crossed over to the Epitomee group (Placebo-Epitomee) and 17 subjects who were assigned to the Epitomee group during the RESET continued Epitomee for an additional 24 weeks (Epitomee-Epitomee).
Safety results from the ELECT study showed that the overall incidence of AEs was no different between the Epitomee subjects who were exposed for an entire year (27 AEs in 12 [70.6%] subjects) versus the Placebo subjects who were switched to Epitomee and were exposed to Epitomee for the first time for a period of 24 weeks (17 AEs in 10 [62.5%] subjects). All AEs in the ELECT study were mild gastrointestinal (GI) events, and all recovered. There were no deaths or SAEs.
Gastric Emptying Study
Epitomee Medical has conducted a prospective, single center, open-label, single-arm study to examine the effect of the Epitomee device on gastric emptying rate in healthy subjects. Ten (10) healthy subjects were enrolled in the study. Subjects completed a gastric emptying test using gastric scintigraphy before taking Epitomee (baseline). Following the baseline scintigraphy, the subjects received the Epitomee device treatment for 10 consecutive days. and underwent another gastric emptying test with capsule intake prior to the test meal.
The results showed that Epitomee was well-tolerated and had a favorable safety profile with no SAEs. There was no significant effect on gastric emptying with Epitomee.
Conclusions
Epitomee is as safe and effective as its predicate device. Epitomee has the same intended use and indications for use, and similar technological characteristics as its predicate device. The minor technological differences between Epitomee and its predicate device raise no new issues of safety or effectiveness. Performance data demonstrate that Epitomee is as safe and effective as the predicate device. Thus, Epitomee is substantially equivalent.
