Overview

TheraPAP is a prototype device (with full documented electrical and isolation safety) being developed by SleepRes for the treatment of obstructive sleep apnea (OSA) that can deliver either standard CPAP at a set pressure or what is called TPAP . TPAP is a pressure control algorithm that lowers the pressure from the set pressure at the beginning of inspiration and does not return the pressure to the full set level until about halfway through expiration. The present study, TheraPAP Comfort, aims at assessing whether TPAP improves patient comfort vs. CPAP during supine wakefulness.

Description

The TheraPAP Comfort Study is an in-office study to assess comfort of TPAP vs. CPAP in CPAP-naïve patients with OSA during supine wakefulness. Patients will be recruited after routine outpatient visits. They will be asked to breath normally for approximately 1 minute in supine wakefulness while being administered background CPAP (at 9 or 13 cmH2O) or TPAP at various pressure drops. TPAP drops will be administered in a paired comparison before or/and after each corresponding CPAP level, according to a randomized design. Eventually, 6 one-to-one comparisons (TPAP vs. corresponding background CPAP or TPAP vs. TPAP) will be made, 3 per each randomized order. As an example, CPAP 9 will be compared to TPAP 1/1 cmH2O drops; CPAP 9 will be compared to TPAP 2/2 cmH2O drops; and TPAP 1/1 cmH2O drops will be compared to TPAP 2/2 cmH2O drops in a random sequence.

Eligibility

Inclusion Criteria:

  • 18 - 70 age range
  • AHI (apnea/hypopnea index) > 10 on a previous HST (Home Sleep Test)
  • CPAP-naive participants
  • BMI (Body Mass Index) >= 18 kg/m^2

Exclusion Criteria:

  1. Current clinically significant sleep disorder other than OSA (Obstructive Sleep Apnea) of a severity that would interfere with study participation or interpretability of data (including central sleep apnea, per central AHI > 5 events/h).
  2. Any chronic lung diseases.
  3. Chronic oxygen therapy.
  4. A serious illness or infection in the past 30 days as determined by investigator.
  5. Patients with hypoglossal nerve stimulation implant.
  6. Any non-previously mentioned vulnerable population.
  7. Any condition that in the investigator's opinion would present an unreasonable risk to the participant, or which would interfere with their participation in the study or confound study interpretation.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
