About this trial
This is an interventional treatment trial for Acute Hearing Loss
Eligibility Criteria
Inclusion Criteria:
- Male or female patients aged ≥ 18
- Patients with a SSHL within 96 hours of its perception
Sudden Sensorineural Hearing Loss including
- idiopathic unilateral Sudden Sensorineural Hearing Loss or
- acute uni- or bilateral acoustic trauma-induced Sudden Sensorineural Hearing Loss
Exclusion Criteria:
- Patients with a history of Meniere's Disease
- Patients with a hearing threshold above 100 dB across at least 6 frequencies
- Patients with endolymphatic, hydrops or history of fluctuating hearing loss
- Patients with suspected perilymph fistula, membrane rupture, retrocochlear lesions or a barotrauma

- Patients with acute or chronic otitis media or otitis externa.
- Patients with congenital hearing loss
- Patients with known hypersensitivity to pioglitazone, other thiazolidindiones or any formulation component
- Use of thiazolidinedione (e.g. pioglitazone, rosiglitazone) in the last 6 months prior to baseline
- Any use of CYP450 2C8 inducers (e.g. rifampicine)
- Fibrates (e.g. gemfibrozil, fenofibrate) in the last 6 months prior to baseline
- Patients where oral administration of pioglitazone is contraindicated (i.e. cardiac failure or history of cardiac failure (NYHA stages I to IV), hepatic impairment, diabetic ketoacidosis, current bladder cancer or a history of bladder cancer, uninvestigated macroscopic haematuria
