Exclusion criteria
Exclusion criteria: 1. Malformation or cochlear ossification 2. Developmental disabilities or psychiatric diseases such as severe depression 3. History of Meniere’s disease 4. Acute or chronic middle ear inflammatory disease 5. Use of thiazolidinedione (e.g. pioglitazone, rosiglitazone) in the last 6 months prior to baseline 6. Chronic (i.e. at least 3 continuous months) oral steroids in the last 6 months prior to baseline 7. Daily nasal/pulmonary steroid in the last month prior to baseline 8. Fibrates (e.g. gemfibrozil, fenofibrate) in the last 6 months prior to baseline 9. Patients with known hypersensitivity to STR001 or any formulation component 10.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the safety and tolerability of STR001 thermogel in patients receiving cochlear implants To assess the efficacy of STR001 thermogel in preserving hearing 6 weeks after cochlear implant surgery as determined by average Pure Tone Audiometry (aPTA) values ;Secondary Objective: To evaluate secondary efficacy parameters of hearing on average Bone Conduction Threshold Audiometry (aBCTA) and individual frequencies by BCTA and PTA. To evaluate the systemic exposure of STR001 after STR001 thermogel administration ;Primary end point(s): Efficacy: Average Pure Tone Audiometry Treshold (aPTA) at 125, 250, 500 and 750 Hz of implanted ear at Week 6. Safety: The incidence and severity of adverse events, serious adverse events, deaths, as well as drug and study discontinuations; The incidence of laboratory abnormalities, based on hematology, clinical chemistry, and urinalysis test results; ECGs; Physical examination; Vital signs ;Timepoint(s) of evaluation of this end point: 6 weeks after CI surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Efficacy (key): BCTA of the implanted ear as the average of the following frequencies: 250, 500 and 750 Hz at Week 6. Efficacy (other): Pure Tone Audiometry will also be assessed at each individual frequency at 125, 250, 500 and 750 Hz at Week 6. BCTA will also be assessed at each individual frequency at 250, 500 and 750 Hz at Week 6. BCTA will also be assessed at each frequency: 250, 500 and 750 Hz at Week 6. Pharmacokinetics: STR001 and its main metobolites (M-III and M-IV) Plasma concentrations. ;Timepoint(s) of evaluation of this end point: Efficay: 6 weeks after CI surgery Pharmacokinetics: At baseline, prior to surgery and after the surgery (4 samples/Patient) | — |
