Osia 2 Pediatric Expansion Study

November 22, 2024 updated by: Cochlear

A Pivotal, Prospective, Multi-center, Open-label Study Evaluating the Safety and Effectiveness of the CochlearTM Osia® 2 System in a Pediatric Population.

The CochlearTM Osia®2 System was cleared by the Food and Drug Administration November 15, 2019 (K191921) for individuals aged 12 years and older who present with conductive or mixed hearing loss (up to 55 dB HL) or single-sided-deafness (SSD).Published and unpublished data suggest significant pre to postoperative benefit and minimal risk in both children and adults who have received the Osia system. Thus the objective of this study is to examine the safety and effectiveness of the Cochlear Osia 2 system in a group of pediatric subjects aged 5 to 11 years who suffer from conductive or mixed hearing loss (up to 55 dB HL), or single-sided-deafness (SSD) with the intent of expanding the indications for use.

Detailed Description

The CochlearTM Osia®2 System was cleared by the Food and Drug Administration November 15, 2019 (K191921) for individuals aged 12 years and older who present with conductive or mixed hearing loss (up to 55 dB HL) or single-sided-deafness (SSD). Published and unpublished data suggest significant pre to postoperative benefit and minimal risk in both children and adults who have received the Osia system. Due to the success of the Osia 2 system in the United States within the currently indicated patient population, clinical providers have since requested the ability to use the Osia 2 system in children aged 11 years and younger who meet the audiometric requirements. As the Osia 2 system is based on existing bone conduction and cochlear implant technologies which each possess a younger age of implantation requirement (5 years for bone conduction and 9 months for cochlear implantation), the current proposal is to align the age at implantation requirement with existing surgical bone conduction technology such as the Baha Connect and Baha Attract Systems to 5 years of age. Therefore, the objective of this study is to examine the safety and effectiveness of the Cochlear Osia 2 system in a group of pediatric subjects aged 5 to 11 years who suffer from conductive or mixed hearing loss (up to 55 dB HL), or single-sided-deafness (SSD) with the intent of expanding the indications for use.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

5 years to 11 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Subjects aged 5 to 11 years of age with the following audiometric criterion:

    • A conductive or mixed hearing loss and still can benefit from sound amplification. The pure tone average (PTA) bone conduction (BC) threshold (measured at 0.5, 1, 2, and 3 kHz) should be better than or equal to 55 dB HL. OR
    • A profound sensorineural hearing loss in one ear and normal hearing in the opposite ear (i.e., single-sided deafness or "SSD"). The pure tone average air conduction hearing thresholds of the hearing ear should be better than or equal to 20 dB HL (measured at 0.5, 1, 2, and 3 kHz).
  2. Prior experience with amplified sound through properly fitted amplification device such as a hearing aid, a CROS device, or a bone conduction device on a softband or sound arc.
  3. Parent or legal guardian who is willing and able to provide written informed consent for the study participant.

Note: Subjects may include individuals seeking new implantation unilaterally (in one ear) or individuals already implanted with a bone-anchored device seeking a second-side implant (sequential bilateral)

Exclusion Criteria:

  1. Insufficient bone quality or quantity to support implantation of both the BI300 Implant and the OSI200 Implant.
  2. Chronic or non-revisable vestibular or balance disorders that could prevent benefit from the device, as determined by the investigator.
  3. Abnormally progressive hearing loss.
  4. Evidence that hearing loss is bilateral retro cochlear or bilateral central origin.
  5. Evidence of conditions that would prevent speech recognition improvement as determined by the investigator.
  6. Skin or scalp conditions that may preclude attachment of the Sound Processor or that may interfere with the use of the Sound Processor.
  7. Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator.
  8. Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling.
  9. Cochlear employees or employees of Contract Research Organizations or contractors engaged by Cochlear for the purposes of this investigation.
  10. Currently participating, or participated within the last 30 days, in another clinical investigation involving an investigational drug or device that could impact the safety or effectiveness of the Osia 2 system as determined by the investigator.
  11. Individuals undergoing simultaneous single-stage aural atresia or microtia repair due to the increased risk of skin complications associated with ear reconstruction.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Adverse Events Quantified by Type and Severity Between Implantation and 6-months Post-surgery.
Time Frame: From implantation to 6 months post-surgery
Adverse events were reported from the time of implantation through 6-months.
From implantation to 6 months post-surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to 6-months Post-surgery in SSQ (Speech, Spatial and Qualities of Hearing Scale) Parent Questionnaire
Time Frame: Baseline before surgery, 6 months post-surgery
Measuring change of speech, spatial, quality and conversational uses of hearing (27 items in 4 sections). Each item is scored by the parent on a scale of 0 to 10 where 0 corresponds to "not at all" and 10 to "perfectly" when rating their child's ability to hear and listen in everyday situations. The score of a participant is determined as the mean of the scores for the 4 different sections. Higher scores indicate less hearing disability.
Baseline before surgery, 6 months post-surgery
Change From Baseline to 4-weeks Post-surgery in Unaided Bone Conduction Thresholds.
Time Frame: Baseline before surgery, 4 weeks post-surgery
The Pure Tone Average (PTA) is calculated as an average of the bone conduction thresholds collected at 500, 1000, 2000, and 4000 Hz. This measure was collected unaided both pre- and post-operatively to ensure no shift in bone conduction hearing as a result of the surgery.
Baseline before surgery, 4 weeks post-surgery
Change in Word Recognition Using Consonant Nucleus Consonant (CNC) Words Presented in Quiet From Unaided Baseline to Aided 6-months Post-surgery.
Time Frame: Baseline before surgery, 6 months post-surgery
The CNC Words test consists of 10 recorded lists of 50 monosyllabic words. For this study, one list is administered per test condition at 60 dBA in sound field and scored as the number of phonemes and words correct, which will be expressed as a percentage correct when analyzed. The CNC word test has a score range of 0-100% with higher values indicating better scores.
Baseline before surgery, 6 months post-surgery
Change in Sentence Recognition in Noise Using the Bramford Kowal Bench Speech-In-Noise (BKB-SIN) From Unaided Baseline to Aided 6-months Post-surgery.
Time Frame: Baseline before surgery, 6 months post-surgery
The Bamford-Kowal-Bench Sentence in Noise test (BKB-SIN) consists of 36 paired lists. List of sentences are presented at 65 dBA with the level of noise varied stepwise at fixed signal to noise ratio to obtain a Speech Reception Threshold (SRT) where participants are able to repeat key words 50% of the time. Score range is not specified as metric is adaptive; lower scores indicate better performance.
