Interventions
A placebo refers to a tablet that has no therapeutic effect on medication.
D-2570 is a novel inhibitor targeting the TYK2 pseudokinase domain, which can inhibit the release of inflammatory factors and participate in immune regulation. D-2570 is being developed as a potential oral therapeutic drug for patients with psoriasis, ulcerative colitis, SLE, and other conditions.
Eligibility Criteria
You may qualify if:
- Subjects who voluntarily take part in the study after being fully informed, sign a written informed consent form (ICF), and agree to follow procedures specified in the study protocol;

- Male and female subjects aged 18 to 45 years (inclusive);
- Male weight ≥ 50 kg, female weight ≥ 45 kg. Body mass index (BMI) = body weight (kg) / height2 (m2). BMI ranging from 19 to 26 kg/m2 (inclusive);
