Description of intervention(s) / exposure
VLS-01 is being developed as a potential anti-depressant treatment for Treatment-resistant depression (TRD). This Phase 1 study will investigate the effects of VLS-01 in healthy participants, when administered buccally (between the cheeks and gums) as “VLS-01-BU” and when administered via intravenous infusion (infusion into the vein) as “VLS-01-IV”.
The study will be comprised of two parts (Part 1 and Part 2) and will include 48 healthy participants, from New Zealand Clinical Research (NZCR). Part 1 will be comprised of 8 participants, all of whom will receive a single 30mg dose of VLS-01 as an intravenous (IV) infusion (VLS-01-IV). Part 1 will be split into 2 groups of 4 participants each, and all safety and pharmacokinetic (PK) data from the first 4 participants will be reviewed before enrolling the remaining 4 participants in Part 1.
Part 2 will be consist of 5 cohorts, with each cohort being comprised of 8 participants each. The cohorts within Part 2 will enroll in sequential order, and depending on when participants join the study, they will enroll in either Cohort 1, 2, 3, 4, or 5 to receive 10mg, 25mg, 45mg, 65mg, or 80mg, respectively. Participant's in Part 2 will receive a single dose of VLS-01 (at the respective dose) via the buccal route (a thin buccal strip(s) placed between the cheeks and gums). After the last participant in each cohort has dosed, all available safety data will be reviewed by the Safety monitoring group (SMG) to determine whether to proceed to the next cohort. Part 1 and 2 will run parallel to each other and the next cohort will not begin until SMG review has been completed and it is confirmed dosing can continue. The stategies that will used to monitor adherance to the intervention would be monitored dosing where all doses of VLS-01-IV and VLS-01-BU will be administered in the presence of the Investigator or their designee.

Outcomes
Primary outcome [1] 331141 0
To assess the safety and tolerability of VLS-01 when administered as single-ascending doses of a buccal formulation (VLS-01-BU) and an intravenous formulation (VLS-01-IV) in healthy adult participants. This will be assessed by checking the frequency and severity of Adverse events (AEs), oral examination (participants in Part 2 only) and also by safety laboratory results. Adverse events will be assessed by symptom focused physical and clinical examination of any autonomic responses that the participant would report from screening to End of study. Vital signs that are assessed include blood pressure (BP), Heart rate, Respiratory rate and Temperature. BP will be assessed using a sphygmomanometer and temperature will be recorded. Clinical laboratory tests and safety labs will use both blood and urine samples.
Suicidal ideation will be measured by Columbia suicide severity rating scale (C-SSRS) score (Baseline to EOS visit on Day 8).
Timepoint [1] 331141 0
Partipants will be assessed daily for adverse events from baseline to end of study visit on Day 8. Participants in Part 2 will have an additional oral examination on screening, Day -1, Day 1 and End of Study/Day 8. All other safety measures for Part 1 and 2 are the same.
Secondary outcome [1] 408955 0
To assess the plasma (PK) characteristics of VLS-01-BU and VLS-01-IV and its 2 predominant metabolites (DMT-NO and IAA) following single-ascending doses in healthy adult participants. Plasma PK parameters including Tmax, Cmax, AUC0-t, AUC0-24, AUC0-24, AUC0-inf, AUC%extrap, Kel, t½ [VLS-01-IV] or apparent t½ [VLS-01-BU], CL or CL/F, Vz/F or Vz, dose normalized Cmax, dose normalized AUC0-t, dose normalized AUC0-4, dose normalized AUC0-inf, and metabolite to parent ratios.
Timepoint [1] 408955 0
On Day 1, plasma samples for PK will be collected predose (within 1 hour before VLS-01 administration). Part 1 samples will be collected at 3, 6, 8, 11, 15, 20, 23, 25, 29, 35, 45, 55, 65 (all ± 1 minute), and 240 minutes (± 10 minutes) after the start of VLS-01-IV administration.
Part 2 samples will be collected at 5, 10, 15, 20, 30, 40, 50, 60 minutes (all ± 2 minutes), 1.5, 2, 4, 8, and 24 hours (all ± 10 minutes) after the start of VLS-01-BU administration. The 24-hour sample for Part 2 will be collected before discharge from the CRU on the morning of Day 2.
Secondary outcome [2] 408956 0
To assess the urine pharmacokinetic (PK) characteristics of VLS-01-BU and VLS-01-IV and its 2 predominant metabolites (DMT-NO and IAA) following single-ascending doses in healthy adult participants. Urine PK parameters includes Ae, Fe, and CLR.
Timepoint [2] 408956 0
On Day 1, urine for PK analysis will be obtained within 2 hours before VLS-01 administration (predose ) and at intervals 0 to 4, 4 to 8, 8 to 12, and 12 to 24 hours (all ± 30 minutes) from the start of VLS-01 administration.

Statistical methods / analysis
As this study has a Phase 1 single-ascending dose (SAD) design, it is not powered for inferential statistics. This sample size is commonly used in studies of this design to obtain sufficient information on the safety and PK before progressing to subsequent studies.

Evaluation of safety will be performed on the Safety Population. Safety data that will be evaluated include AEs, assessment of suicidality, clinical laboratory results, vital signs and continuous pulse oximetry, physical examinations, oral examination (Part 2 only), and ECGs.

Pharmacokinetic parameters will be computed from the individual plasma and urine concentrations using a non-compartmental approach using validated Phoenix WinNonlin® software (Version 8.3 or higher, Certara, USA).

Summary
Brief summary
Depression and anxiety are common mental health disorders that result in individual suffering and have a significant socio-economic impact. In New Zealand, approximately 1 in 7 people will experience depression during their lifetime. Traditional antidepressants often take weeks to months to positively affect mood but are ineffective in approximately 30% of all patients, which often leads to treatment resistant depression (TRD). Treatment of TRD is difficult and may include different pharmacological treatments, or brain stimulation therapies (which are often accompanied by intolerable side effects). However, no single treatment is effective for all TRD patients and there is a significant medical need for effective TRD therapies that are fast-acting and less invasive.

As such, there is an urgent need to improve and expand therapeutic options for these TRD patients. This study will provide critical data and will inform the ongoing development of VLS-01 in the treatment of TRD.
