Moderate to Severe Ulcerative Colitis

The study is being conducted to evaluate the safety, tolerability and pharmakokinetics of HRS-7085 in adults.

This Phase I first-in-human study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of SHR-7590 via subcutaneous or intravenous administration in Chinese healthy participants and patients with moderate-to-severe ulcerative colitis.

This is an open-label, Phase I, investigator-initiated trial (IIT) designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD06-05 in patients with moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD). The enrolled population consists of patients with refractory moderate-to-severe inflammatory bowel disease who have received multiple lines of biologic therapy. Two cohorts are established in the study to explore the optimal biological dose (OBD) for each indication: Cohort 1: Ulcerative Colitis Cohort Cohort 2: Crohn's Disease Cohort The study presets 3 dose groups, which are 3, 6, and 10×10⁶ CAR+T cells/kg respectively. The initial dose group is 3×10⁶ CAR+T cells/kg (Dose Group 1), and dose de-escalation or escalation may be conducted based on the assessment of the Safety Review Committee (SRC). It is expected that no more than 9 patients will be enrolled in each cohort.
