Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Up to eighty (88) healthy men or women of non-child-bearing potential (WNCBP) will be enrolled in this study
This study comprises up to 7 SAD cohorts and up to 4 MAD cohorts.
For all of the SAD cohorts and 3 of the MAD cohorts, 8 participants will be enrolled and will be randomly allocated to receive placebo (2 participants) or active NT-0796 (6 participants) in a double-blind manner. One of the MAD cohorts (likely the 3rd MAD cohort, but the exact cohort to be decided upon by the DEC) will enrol 8 participants to NT-0796 (open-label).

For the blinded cohorts NT-0796 will be provided to the subjects in a blinded manner in liquid formation. Placebo liquid formation to match NT-0796 will be administered. Placebo will be indistinguishable from active treatment.

Dosing of the IP is oral, all dosing will be completed in a controlled unit where participants remain for the duration of treatment period.

The planned doses for the study are as follows:
SAD Cohorts dose ranging from 1mg to 1000mg. The current planned dose schedule is:
Cohort 1 - 1mg
Cohort 2 - 3mg
Cohort 3 - 10 mg
Cohort 4 - 30mg
Cohort 5 - 100mg
Cohort 6 - 300mg
Cohort 7 is currently an optional cohort.
The SAD dosing escalation shall be decided by a dose escalation committee upon review of the safety and PK data of previous SAD Cohorts.

MAD Cohorts dosing plan shall be decided by a dose escalation committee and upon reviewing the SAD Cohort data.

Summary
Brief summary

This project is testing the safety, tolerability, pharmacokinetics (PK, the amount of study drug in your blood)
and pharmacodynamics (PD, how the study drug affects your body) of both single and multiple oral doses of a
new drug called NT-0796.
Up to eighty eight (88) healthy men or women of non-child-bearing potential (WNCBP), aged between 18-55 will be
enrolled in this study in up to seven SAD and up to four MAD cohorts comprising 8 subjects each.
This study will enrol approximately 88 participants, in two parts:
Part A: will involve a single ascending (increasing) dose (SAD) where approximately 56 participants (7 groups
of 8) will be randomised (assigned randomly, like flipping a coin) to receive a single dose of the study drug or
placebo. The placebo will look the same as the study drug but will not contain any medicine.
Part B: will involve a multiple ascending (increasing) dose (MAD) where approximately 32 participants (4
groups of 8) will receive one dose of the study drug or placebo daily for 14 consecutive days (14 doses in
total).
The study is placebo controlled, meaning that some participants will receive capsule(s) containing the active
study drug, and some will receive capsule(s) containing placebo.
For Part A your total participation will last about 8 weeks, of which you will spend 4 days (3 nights) in the clinic.
For Part B your total participation will last about 10 weeks, of which you will spend 17 days (16 nights) in the
clinic.
