About this study

Assessment of the efficacy of Intratympanic platelet rich plasma injection for treatment of idiopathic suden sensorineural hearing loss

Read the detailed description

Sensorineural hearing loss is the collective term for hearing damage to the cochlea and auditory nerve and is by far the most common type of hearing loss in adults, accounting for over 90% of all cases. Sensorineural hearing loss is a heterogeneous disorder, which can arise due to damage to pathway for sound impulses from the hair cells of inner ear to auditory nerve and less commonly brain.

Sensorineural hearing loss is a challenge to physicians, as it progresses with age and causes significant reductions in quality of life and there are no treatments to reverse its effects, other than sound amplification with the use of hearing aids or direct auditory nerve stimulation via cochlear implantation.

Platelet-rich Plasma (PRP) Therapy is a cutting-edge procedure that is revolutionizing the hearing loss and deafness. Intratympanic instillation of Platelet-rich Plasma (PRP) does wonder to the hair cells of inner ear, thus improving the hearing.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Platelet Rich PlasmaBiological

    Sample of patient's blood drawn at time of Treatment; the blood drawing occurs with addition of anticoagulant such as citrate dextrose A to prevent platelet activation prior to its use.

    Obtain whole blood by venipuncture in acid citrate dextrose (ACD) tubes. Centrifuge the blood using a 'soft' spin. Transfer the supernatant plasma containing platelets into another sterile tube (without anticoagulant).

    Centrifuge tube at a higher speed (a hard spin) to obtain a platelet concentrate.

    The lower 1/3rd is PRP and upper 2/3rd is platelet-poor plasma (PPP). At the bottom of the tube, platelet pellets are formed.

    PRP activation prior to injection. PRP can be activated exogenously by calcium chloride.

  • local anesthesia in external auditory canalDrug

    local anesthesia cream (lidocaine cream) will be applied in external auditory canal for 15 minutes

  • Intratympanic InjectionProcedure or surgery

    0.5-1 ml of PRP will be injected in middle ear cavity in round window niche Using microscope or endoscope.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in Pure Tone Averages

    Continuous pure tone averages calculated from pure tone audiometry will be summarized using the mean, standard deviation, median, 25th percentile, 75th percentile, minimum and maximum.

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Platelet Rich Plasma, local anesthesia in external auditory canal and Intratympanic Injection in people with Hearing Loss, Sudden and Hearing Loss, Sensorineural, run by Assiut University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mahmoud H Ali, MBBS (201062805374 ext. 71621, mahmoud.nwawa@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in Pure Tone Averages (time frame: 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2023.
