COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
An Adaptive Design Study for the Assessment of the Safety, Tolerability and Pharmacokinetics of RYI-018 after Single Dosing in Healthy Volunteers and Repeat Dosing in Subjects with Non-Alcoholic Fatty Liver Disease (NAFLD).

Part A: A total of 24 patients will be randomized into 3 cohorts. The anticipated dose levels of RYI-018 for Part A of the study will be 0.6 mg/kg (Cohort 1), 1.2 mg/kg (Cohort 2), and 2.5 mg/kg (Cohort 3), administered by intravenous (IV) infusion weekly as single ascending doses. Part A of the study will be conducted in healthy volunteer only
.
Part B: A total of 60 patients will be randomized into 3 cohorts that will receive three different dosages. The final doses of RYI-018 selected for Part B of the study will be based on the results from Part A. Subjects will be given a total of four (4) IV doses, administered by IV infusion at weekly intervals per the randomization plan. Part B of the study will be conducted in patients with NAFLD only..

The trial will be conducted in accordance with ICHGCP guidelines, and the National Statement. The Bird Rock Bio delegated monitor will contact and visit the site regularly and will be allowed on request to inspect the various records of the trial [case report forms (CRFs) and other pertinent data] provided that subject confidentiality is maintained. It will be the monitor's responsibility to inspect the CRFs at regular intervals throughout the study, to verify adherence to the protocol and the completeness, consistency and accuracy of the data being entered on them. The monitor must verify that the patient received the study drug assigned by the randomisation centre (by reviewing the written confirmation of the randomisation by IxRS). The monitor will have access to laboratory test reports and other subject records needed to verify the entries on the CRF. The investigator will cooperate with the monitor to ensure that any problems detected in the course of these monitoring visits are resolved. Bird Rock Bio delegated monitors and auditors will have direct access to appropriate parts of records relating to subjects participating in this study for the purpose of verifying the data provided to Bird Rock Bio. The site will permit monitoring, audits, Institutional Review Boards/Independent Ethics Committee (IRB/IEC) review and regulatory inspections by providing direct access to the source data and documents.

Safety
Statistical methods / analysis
Safety information after administration of single dose of RYI-018 in healthy subjects for Part A and after administration of multiple doses of RYI-018 in patients with NAFLD for Part B will be evaluated by tabulating adverse experiences and clinical assessment of clinical laboratory data.
Part A:
The primary objective regarding safety will be evaluated based on the following calculations:
If a particular adverse experience is not observed in any of the 6 subjects at each dose level, the true incidence rate is less than 0.24 with 80% confidence (0.32 with 90% confidence).
Part B:
The primary objective regarding safety will be evaluated based on the following calculations:
If a particular adverse experience is not observed in any of the 15 subjects at each dose level, the true incidence rate is less than 0.10 with 80% confidence (0.14 with 90% confidence).

Summary
Brief summary
This study will be conducted as an adaptive design, randomized, parallel group study to evaluate the pharmacokinetics (PK) and safety of single IV doses of RYI-018 in healthy volunteers and repeat IV doses of RYI-018 in subjects with NAFLD.
Part A of the study will be conducted as a double-blind, placebo controlled, randomized, single ascending dose study to determine the safety, tolerability, and PK of RYI-018 in healthy volunteers.
During Part B of the study, subjects in each cohort shall be randomized to either RYI-018 or placebo. Three (3) cohorts which will include 20 subjects per cohort with 15 subjects randomized to receive active drug administered at weekly intervals and 5 subjects randomized to receive placebo in each cohort at weekly intervals, per the randomization plan.
The primary objective of Part A of the study will be to assess the safety and tolerability of single IV ascending doses of RYI-018 when administered to healthy adult volunteers
The primary objective of Part B of the study is to evaluate the safety and tolerability of multiple doses of RYI-018 after 4 weeks of dosing in subjects with NAFLD.
