IVD (In Vitro Diagnostic)

Based on the provided information, the PrePex device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use is for "circumcision of adult males." This is a surgical procedure performed on the body, not a test performed on a sample taken from the body.
Device Description: The device is described as a physical tool used for a surgical procedure (circumcision). It does not involve analyzing biological samples.
Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample. There is no mention of detecting or measuring substances in a sample.

IVD devices are used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or screening. The PrePex device is a surgical tool used for a physical procedure.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance Pre-Clinical Data:

The PrePex has been subject to biocompatibility testing per ISO 10993-. 1:2009 and FDA Blue Book Memorandum #G95-1 (cytotoxicity, dermal irritation, dermal sensitization). The results of these tests were negative and support the safe use of the PrePex in contact with non-intact skin.
. The PrePex successfully passed a series of bench tests including Delivery Ring Test, Elastic Ring Elongation Test, Inner Ring Surface Smoothness Test, and Final Product Measurements Test.

Performance Clinical Data:

The PrePex Device was subject to a clinical study initiated and sponsored by the government of Rwanda. The objectives of the study were to assess the safety and efficacy of the PrePex Device for nonsurgical circumcision in adult males. A total of 50 healthy uncircumcised men aged 18 to 35 years were enrolled. The device was placed and removed by a physician or a nurse in a non-sterile setting, with no need for anesthesia or suturing. The subjects were seen regularly throughout the 6-week study, with pain assessed using a visual analog scale (VAS) at each visit. The results of this study show that all subjects achieved the endpoint of complete circumcision with no cases of bleeding and no unexpected adverse events related to the procedure or the device. Only 1 case of diffuse edema, which was resolved with minimal intervention (Ibuprofen), was reported following device removal. All subjects returned to their daily routines soon after device placement and removal, with no sick/absent days associated with the procedure. The median time for complete healing was 21 days after device removal, i.e., 28 days post-placement; the mean time was 25.3 days after device removal. There were no device-related incidents, the device functioned as expected in all subjects and there were no instances of erroneous placements of the device.
As a result of the above mentioned study, the Government of Rwanda sponsored a second study in which the performance of the PrePex device was compared to a WHO approved method of surgical circumcision in a prospective, randomized, comparative study. The study included a total of 180 participants randomly divided into 2 unbalanced study arms: PrePex arm of 120 subjects and surgical circumcision arm of 60 subjects. The study period per subject was 9 weeks.
The primary objective of the study was to assess the total operative time of the PrePex Device circumcision procedure versus the total operative time of surgical circumcision procedure, as defined in the Framework for Clinical Evaluation of Devices for Adult Male Circumcision (February 2011). Additionally, a number of secondary objectives were evaluated amongst them were: clinical adverse event rates, procedure preparation time and time to complete healing.

All PrePex Device procedures were performed by experienced operators who participated in the first study. The procedures were carried out in a clean environment in a minor surgery room. The procedure was bloodless, and was conducted with no anesthesia or sutures. Subjects participated in regular follow-up visits at specified intervals.

The surgical circumcision procedure used was the dorsal slit method which was performed by a surgeon highly experienced in adult male circumcision.

The study yielded the following results:

The average PrePex total procedure time of 3 minutes and 11 seconds is much shorter than the surgical circumcision (15 min. and 33 sec.).
There were NO related AEs in the PrePex study arm compared to 7 related mild AEs in the surgical arm.
There were 3 mild un-related AEs and 1 moderate un-related AE in the PrePex arm and 1 moderate un-related AE in the surgical arm.
The average procedure preparation time was 3min and 24 sec for the PrePex procedure compared to 8 min and 50 sec for the surgical procedure.
Average time to complete healing was 38 days post PrePex device o removal and 30 days post surgery.

Device Description:

Intended Use:

PrePex is indicated for circumcision of adult males. PrePex is intended to be placed and removed by a health care professional trained in male circumcision and in use of the PrePex device.

Technological Characteristics:

The device is designed to block blood supply to the foreskin by clamping the foreskin between the outer Elastic Ring and the Inner Ring. The device remains on the patient foreskin until the physician determines to remove the foreskin. This can be immediate, after placing the device and up to 1 week later when the device is removed.

Performance Pre-Clinical Data:

The PrePex has been subject to biocompatibility testing per ISO 10993-. 1:2009 and FDA Blue Book Memorandum #G95-1 (cytotoxicity, dermal irritation, dermal sensitization). The results of these tests were negative and support the safe use of the PrePex in contact with non-intact skin.
. The PrePex successfully passed a series of bench tests including Delivery Ring Test, Elastic Ring Elongation Test, Inner Ring Surface Smoothness Test, and Final Product Measurements Test.

Performance Clinical Data:

The PrePex Device was subject to a clinical study initiated and sponsored . by the government of Rwanda. The objectives of the study were to assess the safety and efficacy of the PrePex Device for nonsurgical circumcision in adult males. A total of 50 healthy uncircumcised men aged 18 to 35 years were enrolled. The device was placed and removed by a physician or a nurse in a non-sterile setting, with no need for anesthesia or suturing. The subjects were seen regularly throughout the 6-week study, with pain assessed using a visual analog scale (VAS) at each visit. The results of this study show that all subjects achieved the endpoint of complete circumcision with no cases of bleeding and no unexpected
adverse events related to the procedure or the device. Only 1 case of diffuse edema, which was resolved with minimal intervention (Ibuprofen), was reported following device removal. All subjects returned to their daily routines soon after device placement and removal, with no sick/absent days associated with the procedure. The median time for complete healing was 21 days after device removal, i.e., 28 days post-placement; the mean time was 25.3 days after device removal. There were no devicerelated incidents, the device functioned as expected in all subjects and there were no instances of erroneous placements of the device.

As a result of the above mentioned study, the Government of Rwanda . sponsored a second study in which the performance of the PrePex device was compared to a WHO approved method of surgical circumcision in a prospective, randomized, comparative study. The study included a total of 180 participants randomly divided into 2 unbalanced study arms: PrePex arm of 120 subjects and surgical circumcision arm of 60 subjects. The study period per subject was 9 weeks.
The primary objective of the study was to assess the total operative time of the PrePex Device circumcision procedure versus the total operative time of surgical circumcision procedure, as defined in the Framework for Clinical Evaluation of Devices for Adult Male Circumcision (February 2011). Additionally, a number of secondary objectives were evaluated amongst them were: clinical adverse event rates, procedure preparation time and time to complete healing.

The surgical circumcision procedure used was the dorsal slit method which was performed by a surgeon highly experienced in adult male circumcision.

The study vielded the following results:

o The average PrePex total procedure time of 3 minutes and 11 seconds is much shorter than the surgical circumcision (15 min. and 33 sec.).
There were NO related AEs in the PrePex study arm compared to o 7 related mild AEs in the surgical arm.
There were 3 mild un-related AEs and 1 moderate un-related AE o in the PrePex arm and 1 moderate un-related AE in the surgical arm.
The average procedure preparation time was 3min and 24 sec for o the PrePex procedure compared to 8 min and 50 sec for the surgical procedure.
Average time to complete healing was 38 days post PrePex device o removal and 30 days post surgery.

Adverse Events

In the clinical studies there were no serious adverse events related to the PrePex device or the PrePex procedure.

In the first study, subjects reported minimal pain at all steps in the process except device removal. During device removal subjects experienced moderate pain, therefore, after the first 20 subjects, a 1-g dose of oral analgesia approximately 30 minutes before device placement and before device removal was administered. No additional painkiller was required in any subject.
