Brief Summary

This study adopts a multicenter, randomized, double-blind, low-medium-high dose group and placebo parallel controlled clinical study design. After screening, patients with active ulcerative colitis who meet the inclusion criteria and do not meet the exclusion criteria will be randomized by 1:1:1:1 to Hemay007 400 mg BID group, 800 mg QD group, 600 mg BID group or placebo group, with proposed 72 cases in each group. After 12 weeks of double-blind inductive treatment period, the patients will enter the Hemay007 open treatment period of 12 weeks when Hemay007 600 mg BID will be used as the medication regimen. All randomized subjects who have received the investigational drug should be subjected to a 4-week observation after the end of treatment.

Oral administration of sulfasalazine (SASP) and/or 5-aminosalicylic acid (5-ASA); Oral administration of corticosteroids; Azathioprine or 6-mercaptopurine; Anti-TNF-α treatment: infliximab or adalimumab, etc.;

• If the patient is using the following drugs to treat ulcerative colitis at the time of screening, it is necessary to receive stable treatment during the screening period and the following requirements during the study period are as follows:
• Oral administration of sulfasalazine (SASP) and/or 5-aminosalicylic acid (5-ASA) maintaining stable for at least ≥ 2 weeks prior to endoscopy during the screening period and maintaining stable during the study period; and/or

Acceptable contraceptive methods in this study include: a. abstinence; b. hormones (oral intake, patch, ring, injection, implantation) combined with male condoms. This measure must be applied at least 30 days prior to the first administration of investigational drug, otherwise another acceptable method of contraception must be used; c. intra-uterine device (IUD) combined with male condoms; d. barrier method (diaphragm, cervical cap, sponge) combined with male condoms; exceptional circumstances: a) females who have been menopausal for 5 years and more, and b) surgical sterilization (proof should be provided).
