Brief summary
The main aim of this study is to see if the drug TAK-781 is safe for healthy volunteers and for participants with PSC. The study will also look at how well participants can tolerate TAK-781. In addition, the study will check how the body absorbs, uses, and gets rid of TAK-781 (Pharmacokinetics \[PK\]), how the drug affects the body (Pharmacodynamics \[PD\]), and how the body's immune system reacts to TAK-781 (Immunogenicity). The study consists of two phases (Phase 1a and 1b). Phase 1a includes two parts: Part 1 (Single Ascending Dose \[SAD\]) and Part 2 (Multiple Ascending Dose \[MAD\]). In Part 1, healthy participants will receive either single dose of TAK-781 or a placebo. A placebo looks the same as TAK-781 but has no medicine in it. In Part 2, healthy participants will receive multiple doses of TAK-781 or a placebo. In Phase 1b (Part 3), participants with large duct, non-cirrhotic PSC will receive a single dose of TAK-781. Participants will be in the study for about 36 weeks.

Lipid parameters may be repeated once under fasting conditions at the principal investigator's discretion. Eligibility will be determined based on the repeated results. 9. The participant has eGFR rate \<=90milliliter per minutes per 1.73 square meters (mL/min/1.73m\^2) at screening. 10.

The participant has a confirmed supine systolic blood pressure \>=140 millimetres of mercury (mmHg) and/or diastolic blood pressure \>=90 mmHg at screening. If the participant's supine blood pressure exceeds these thresholds, the measurement should be repeated twice after the participant has remained in the supine position for at least 10 minutes.
