Eligibility
Key inclusion criteria

Key exclusion criteria
• History of diseases or surgeries of the gastrointestinal tract.
• Have had cancer in the last three years (some treated skin cancers are permitted).
• Have a current infection, or infections that keep coming back despite treatment
• History of any other medical, psychiatric, or substance abuse condition, concurrent medical therapies, or abnormal laboratory values that in the opinion of the Investigator may put the subject at greater safety risk, influence response to study drug, or interfere with study assessments.
• Known hypersensitivity to lenabasum or any of its excipients.
• Have an estimated creatinine clearance <50 mL/min at Screening using the Cockcroft Gault formula.
• Have uncontrolled hypertension
• Are a regular user of nicotine products (e.g. smoke more than 10 cigarettes per day).
• Have an average alcohol intake of more than 10 drinks per week (women) or 15 drinks / week (men). One drink equals 360 mL beer, 150 mL wine, or 45 mL spirits.
• Use of medications which are known strong cytochrome P450 isoenzyme substrates/inducers/inhibitors within 30 days prior to study dosing and for the duration of the study.
• Participation in any other clinical study
Additional criterion apply for subjects with hepatic impairment, including but not limited to:
• Presence of severe hepatic encephalopathy of Grade 3 or 4
• Presence of acute liver disease
• History of liver transplant

Statistical methods / analysis
Sample Size: No formal sample size calculation has been performed for this study. The sample size of 8 subjects to obtain approximately 6 evaluable subjects per hepatic function group is chosen based on feasibility, FDA guidance, and clinical judgment to provide adequate precision in describing the effect of hepatic impairment on lenabasum PK.
Statistical Analysis: To assess the effect of hepatic impairment on the plasma PK of lenabasum, log-transformed Cmax and AUC will be separately analyzed using a linear fixed-effect analysis of variance model with hepatic function group as a fixed-effect. Transformed back from the logarithmic scale, geometric least-squares means together with the associated 2-sided 95% confidence intervals (CIs) for Cmax and AUC will be estimated and presented. Also, ratios of geometric least-squares means (hepatic impairment group versus matched control group) together with 2-sided 90% CIs will be estimated and presented. In addition, the relationships between log-transformed plasma PK parameters (eg, Cmax, AUC, CL/F, and Vd/F) for lenabasum measures of hepatic impairment (ie, Child-Pugh score and/or each of its components) will be assessed using a regression model across hepatic function groups.

Summary
Brief summary
This Phase 1 study aims to evaluate, characterize, and compare the PK and short-term safety profile of single-dose orally administered lenabasum in subjects with varying degrees of hepatic impairment and in matched healthy control subjects with normal hepatic function. The data generated from this study may allow subjects with a broader range of hepatic function to enter future studies and eventually receive this medication should it be approved for use by regulatory authorities.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
We do not plan to make individual subject data publicly available.
Deidentified Individual subject data is to be used in support of NDA filing and therefore, would compromise business needs if required to make available prior to Marketing Authorization Approval.
