E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine efficacy on central vestibular compensation of 3 doses versus placebo of L-acetylleucine within 4 days of intravenous administration in patient hospitalised for acute vestibular neuritis. |
|
E.2.2 | Secondary objectives of the trial |

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- patients aged above 18 years, - Patient admitted to the hospital for vertigo related to acute vestibular neuritis, - Vestibular neuritis (acute unilateral vestibulopathy) defined as : • acute or subacute onset of severe, prolonged rotatory vertigo, nausea and postural imbalance that began less than 48h before the inclusion visit,
• horizontal spontaneous nystagmus with a rotational component beating toward the unaffected ear (fast phase), without evidence of central vestibular lesion,
• Pathological Head ImpulseTest (Halmagyi-Curthoys) toward the affected side,
- Negative pregnancy test at inclusion for woman of child bearing potential and using an efficient contraceptive (implants, injectables, combined oral contraceptives, some intra-uterine devices or vasectomised partner related to note 3 of the CPMP/ICH/286/95) for at least 2 months before the study and one month after the end of the study,
|
|
E.4 | Principal exclusion criteria |
*Criteria related to pathologies: - Chronic vestibular dysfonction before the acute onset of symptoms, - Acute, unilateral (same side as the affected ear) tinnitus during, or after the onset of vertigo, - Acute hearing loss during, or after the onset of vertigo, - Central ocular motor dysfunction - Central vestibular dysfunction - Symptoms of cerebellar disorder - Symptoms of central neurological disorder - History or symptoms of vestibular migraine - Recent history of ear and/or head trauma, - Tympanic membrane perforation - Chronic otitis, - No deficit on Bitehrmal Caloric Test performed at D3
* Criteria related to treatments - Patient with history of hypersensitivity to acetylleucine or excipients, - History of systemic or transtympanic administration of aminoglycosides or any other ototoxic substances, - More than two antivertigo drug oral or intravenous administration before inclusion visit, - Patient taking non allowed medications (see section 7 of the protocol)
*Criteria related to the population: - medical history of major medical, psychiatric illness or surgery which, in judgement of the investigator, puts them "at risk" or is likely to modify their handling of the study drug, - female who is pregnant or breast feeding or not using contraception, or planning to become pregnant, - participation to an other clinical trial in the previous month or during the study, - patient who is not able to understand the information (for linguistic or psychiatric reasons) and to give informed consent.
