Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Suspected or confirmed diagnosis of fibrotic MASH suggested by the historical data and meets at least 1 criteria for fibrotic MASH 4. Confirmed diagnosis of HFpEF 5. Structural and/or functional heart disease based on echocardiographic evaluation. 6. eGFR ≥45 mL/min/1.73 m2 7. Female patients of reproductive potential are eligible if they have a negative serum pregnancy test (beta human chorionic gonadotropin), are not breastfeeding, and do not plan to become pregnant during the study and agree to use 1 highly effective birth control method during the study and for at least 30 days after study drug administration. Highly effective birth control methods include hormonal and non-hormonal intrauterine device, combination estrogen-progesterone hormonal contraception (oral, transdermal, or vaginal), tubal ligation, a vasectomized or sterile male partner, or sexual abstinence (defined as refraining from heterosexual intercourse), from Screening, throughout the study and for at least 30 days after study drug administration. Exclusion Criteria: 1. Patients with cirrhosis and other etiologies of chronic liver disease 2. PEth value of ≥20 ng/mL measured at Screening OR history of significant alcohol consumption for a period of more than 3 consecutive months within 1 year prior to Screening. 3. Thyroid disease: 1. Active hyperthyroidism 2. Untreated clinical hypothyroidism defined by TSH \>7 IU/L with symptoms of hypothyroidism or \>10 IU/L without symptoms 4.
