General information about the trial
|
|||
Main objective of the trial |
To demonstrate the efficacy of SENS-111 in Acute Unilateral Vestibulopathy (AUV)
|
||
Protection of trial subjects |
In exceptional circumstances, when the patient was presenting with a severe, unbearable vertigo lasting more than 4 days, a rescue medication could be given to the patient from Day 5 and onwards.
|
||
Background therapy |
No background therapy. | ||
Evidence for comparator |
There is no approved therapy for AUV. Many patients are severely impaired by vertigo, nausea and vomiting in the acute phase: these symptoms are major targets for treatment. Nausea and vomiting are usually treated with antihistamins, mostly dimenhydrinate or even benzodiazepines in severe cases which induce sedation. The effects of corticosteroids and vestibular exercises are still debated. Those treatment were not permitted in the study. | ||

Date |
Amendment |
||
09 Feb 2017 |
This amendment was prepared to address Grounds for Non-acceptance raised during the Voluntary Harmonisation Procedure and included the following changes:
- Exclusion criterion no. 28 was amended to exclude subjects (male or female) who were unwilling to use 1 of the highly effective contraception therapies listed in the exclusion criteria. In addition, an appendix was added to the protocol to provide complete guidance on highly effective birth control. Also the wording “effective contraception” was changed to “highly effective contraception” throughout the protocol.
- Inclusion criterion no. 1 was amended to include an upper age limit and to provide a justification for the selected upper age limit. The sponsor proposed an upper age limit of 75 years as being most representative of the target subject population.
- a new section Unblinding Procedure was added to the protocol. A complete discussion of unblinding procedures using the Interactive Web Response System was presented in this new section
- protocol’s withdrawal criteria was modified to include the worsening of nausea or vertigo as demonstrated on 2 successive VAS scale scores. Additionally, the criteria were expanded to include the onset of new neurological symptoms and hearing loss.
- some statement were added indicating that:
*biological samples were to be analyzed locally and destroyed after the analyses. No further uses of the samples were planned for additional research.
* no change or amendment to the protocol would be implemented before approval was received by the regulatory authority and ethics committees.
* no protocol waivers were to be accepted and any protocol deviation will be assessed by the sponsor. In the event of breach of fundamental obligations including but not limited to breach of the clinical trial protocol, breach of the applicable laws and regulations or breach of the ICH guideline on GCP, the sponsor will report major noncompliance to the Regulatory Authorities |
||
08 Sep 2017 |
• Exclusion criterion no. 22 on contraception was amendment to indicate that contraception had to be used for at least 3 months after the last IMP intake
• at some specific sites, an ancillary test using the Caloric test or vHIT were conducted
• clarification that consent and screening were to be done no more than 12 hours apart |
||
05 Nov 2018 |
- clarification that around 38 sites in Europe, Israel, USA, and South Korea were planned to be involved in the study
- update of sample size calculation so that the number of randomized subjects was reduced to 105 (35 subjects per treatment arm)
- Exclusion criterion no. 16 updated so to exclude subjects if they had taken more than 3 doses of the listed concomitant medications
- The ECG assessment was moved from V2 to V1 (Screening) and Romberg tests were added at V2, V3, and V4
- “Unrelated” was added as an assessment option of AE relationship |
