The female partner of a male participant who does not meet the definition of postmenopausal or permanently surgically sterile is considered of childbearing potential and is required to use a highly effective method of contraception consistently from 30 days prior to Day 1 until the EOS visit of the male participant. Male participants who are surgically sterilized, performed at least 6 months prior to screening, may be enrolled. Male participants must also agree not to donate sperm from Day 1 until the EOS visit.

排除标准

- •HIV: Positive test for HIV antibody.
- •Other active infections or history of infections as follows:
- •Infection requiring treatment with oral antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 14 days before the Baseline (Day 1) Visit.
- •A serious infection, defined as requiring hospitalization or IV anti-microbial therapy within 2 months prior to the Baseline (Day 1) Visit.
- •A history of opportunistic, recurrent, or chronic infections at Investigator's (or designee's) discretion.
- •History of significant allergy to any medication as judged by the Investigator (or designee).
- •Use of any prescription medication within 14 days prior to D1 or 5 half-lives, whichever is longer; or use of over-the-counter medications or supplements within 7 days prior to D1 (except for contraception, paracetamol and standard dose of multivitamins).
- •Participant has used more than 5 cigarettes per day, or equivalent with other nicotine containing products, in the 3 months prior to Day 1, or is unwilling to avoid nicotine use during confinement periods.
- •Participant who consumes on average more than 14 units of alcohol per week for female or 21 units of alcohol per week for male in the 6 months prior to Day 1 (1 unit = 10 mg alcohol), or who has a positive alcohol breath test at Screening or Day -

- •Pregnant or lactating women.
- •Cannot commit to full participation in all trial procedures.
- •Any other circumstances that, in the Investigator (or designee) judgment, may increase the risk associated with the participant's participation in and completion of the study or could preclude the evaluation of the participant's response.
- •Known exposure to anti-TL1A or any type of anti-TL1A therapy.
- •Known exposure to anti-IL23 or any type of anti-IL23 therapy.
