Outcomes
Primary outcome [1] 287633 0
To determine the safety of noribogaine in a healthy normal participant population. This will be assessed by observations including physical examinations, clinical laboratory tests and ECGs
Timepoint [1] 287633 0
These will be assessed frequently over 72 hours then periodically duing the next 6 days following a single dose.
Primary outcome [2] 287634 0
To determine the tolerability of noribogaine in a healthy normal participant population. This will be assessed by clinical observation and adverse event reporting.

Expected adverse events are not known with certainty but may include events commonly seen with serotonergic medications such as certain antidepressants and opioids. Adverse events include participant reports and clinically significant abnormalities of observations defined in the protocol. All adverse events will be assessed by the principal investigator.
Timepoint [2] 287634 0
These will be assessed frequently over 72 hours then periodically during the next 6 days following a single dose
Secondary outcome [1] 298561 0
To determine the pharmacokinetic profile of noribogaine in the study participants. This will be assessed using blood samples that will be analyzed for noribogaine.
Timepoint [1] 298561 0
Samples will be obtained frequently over 72 hours, then periodically over the next 6 days following a single dose.
Secondary outcome [2] 298562 0
To determine the pharmacodynamic profile of noribogaine in the study participants. This will be measured by physiological assessments of analgesic and mu opioid agonist activity
Timepoint [2] 298562 0
This will be assessed frequently over 72 hours then periodically over the next 6 days following a single dose.

Can healthy volunteers participate?
Yes
Key exclusion criteria
a) Evidence from medical history, physical or laboratory examinations of significant neurologic, psychiatric, cardiac, respiratory, renal, hepatic, endocrine, gastrointestinal, immunological condition or any other diagnosed conditions that might interfere with the absorption, distribution, metabolism or excretion of the drug, interfere with the ability to accurately record study measurements (e.g., cataracts) or which may potentiate or predispose to undesired effects.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After obtaining consent and confirming eligibility, the participant will be randomised in the study. Study drug will be prepared for each participant by pharmacy staff, according to the randomisation code. All clinical staff will remain blinded. Individual randomisation envelopes will be provided in case the identity of study drug administered to a participant needs to be known.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization by computer
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
