Description of intervention(s) / exposure
OLX75016 is a chemically synthesized double stranded siRNA targeting expression of the Mitochondrial Amidoxime Reducing Component 1 (MARC1) enzyme for the treatment of nonalcoholic fatty liver disease(NAFLD) with liver fibrosis. OLX75016, which is administered by subcutaneous (SC) injection,

OLX75016 and a matching placebo will be administered as SC injections in the abdominal region. This study will be conducted in two parts: Part A (SAD) and Part B (MAD).
Each study part will enrol patients with Non-Alcoholic Fatty Liver Disease (NAFLD).

- Part A (SAD) NAFLD Patients: Up to 20 patients over 3 cohorts
- Part B (MAD) NAFLD Patients: Up to 8 patients over 2 dose escalation cohorts (up to 4 patients per cohort)

- Part A Single Ascending Dose (SAD) NAFLD Patients: NAFLD patients will be enrolled and randomized to 3 cohorts with first cohort having 4 participants, second and third cohorts having 8 participants to receive single doses of OLX75016 or placebo (ratio 3:1 active: placebo). The dose levels will be 90 mg (Cohort 1), 200 mg (Cohort 2) and 45 mg (Cohort 3). At the discretion of the study Sponsor, in consultation with the Safety Review committee (SRC), additional cohorts may be added to evaluate intermediate dose levels. Patients with NAFLD will be screened between Day -28 to Day -2. Eligible participants will be admitted to the clinic on Day -1. Following confirmation of eligibility, participants will be randomized to receive OLX75016 or a placebo before dose administration on Day 1. Doses will be administered in the clinic, under the supervision of site staff . All participants will be confined to the clinic until the completion of all safety/tolerability and PK assessments on Day 3. Sentinels are not required for NAFLD patient cohorts.

Participants will be required to return to the clinic for additional outpatient safety/tolerability assessments on Day 4, 7, 14, 28, 42, 84, 112, 140, 168, 196 and 224. Participants will be discharged from each visit following completion of all safety and PK assessments, the end of study (EoS) visit will be on Day 224. Compliance will be monitored by site staff witnessing of dosing and will be documented in participant study files. If participants experience any clinically significant (CS) AEs during the confinement period, they may remain in the clinical facility for further observation at the discretion of the Principal Investigator (PI).

- Part B Multiple Ascending Dose (MAD) NAFLD Patients: NAFLD patients will be enrolled and randomized to 2 cohorts (Cohorts 1 and 2; n=4 per cohort) to receive multiple doses of OLX75016 or placebo (ratio 3:1 active: placebo), with 2 dose levels planned (administered approximately 3 months apart on Day 1 and Day 85). At the discretion of the study Sponsor, in consultation with the SRC, additional cohort(s) may be added to evaluate (an) additional dose level(s).
Dosing in MAD NAFLD Cohort 2 may commence 28 days after the first participant in MAD NAFLD Cohort 1 has completed first dose administration.
Sentinel dosing will not be required in Part B (MAD), unless recommended by the SRC following review of data from Part A (SAD). Dosing in each patient cohort will commence only after SRC confirms dosing in SAD NAFLD Cohort 3.
Compliance will be monitored by site staff witnessing of dosing and will be documented in participant study files. If patients with NAFLD experience any clinically significant (CS) AEs during the confinement period, they may remain in the clinical facility for further observation at the discretion of the Principal Investigator (PI).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Code-break tamper-evident envelopes containing treatment allocation per participant will be provided to the study site for emergency unblinding if required.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
All study participants who sign an informed consent form at screening will receive a unique screening number. Participants who meet the study eligibility criteria will be assigned a randomization number prior to first dose administration on Day 1 by the unblinded pharmacy personnel as per site standard process,which corresponds to a study treatment (OLX75016 or placebo). The allocation to OLX75016 or placebo will be performed using a block randomization algorithm. and will be documented in the study randomization schedule.

Statistical methods / analysis
Detailed methodology for the summation and statistical analysis of the data collected will be documented in a Statistical Analysis Plan. Summaries will be presented separately for Part A (SAD) and PartB (MAD), by dose level within study part and overall within study part. For descriptive statistics, continuous data will be summarized by dose level and time point using the number of observations, arithmetic mean,standard deviation (SD), median, minimum and maximum. Discrete data will be summarized using counts and percentages. All available data will be included in data listings. Data tabulations will be performed forspecific analysis populations.

All Screened Analysis Set
The All Screened Analysis Set (ASS) will include all participants who sign an informed consent form at screening and receive a unique sequential number (i.e., screening number).

Safety Analysis Set
All participants who receive at least one dose of study drug will be included in the Safety Analysis Set and will be analysed as per the actual treatment received, if this differs from that to which the participant was randomized.

Pharmacokinetic Analysis Set
The PK Analysis Set will include all participants who receive at least one dose of study drug (OLX75016)and have sufficient post-dose data to be able to reliably determine at least one PK parameter. Participantswill be analysed according to treatment received.
