NCT06864182

Brief Summary

The study comprises three parts: single ascending dose (SAD) studies of CX2101A tablets at 40 mg, 100 mg, and 160 mg; a relative bioavailability (BA) study comparing single-dose administration of 100 mg CX2101A tablets and enteric-coated tablets; and a multiple ascending dose (MAD) study of CX2101A tablets. The BA study (100 mg) is integrated into the SAD study(Nested within the SAD protocol to optimize resource utilization).

Eligibility Criteria

Age GroupsAdult (18-64)

You may qualify if:

  • For male volunteers, the body weight should be ≥ 50.0 kg, and for female volunteers, the body weight should be ≥ 45.0 kg.

  • No history of major diseases, and the results of physical examination, vital signs, 12-lead electrocardiogram, chest X-ray examination and laboratory tests during the screening period are normal, or although slightly beyond the normal reference value range, they are judged by the investigator to have no clinical significance.

  • Subjects who used any prescription drugs, over-the-counter drugs, traditional Chinese patent medicines, Chinese herbal medicines, vitamins, or health foods within 28 days before screening or within 5 drug half-lives (whichever is longer).
  • Female subjects who are pregnant or breastfeeding, or those with a positive blood/urine pregnancy test (only for WOCBP) at any time during screening.
  • Positive results or results exceeding the upper limit of the reference range for the four hemodialysis tests: hepatitis B surface antigen (HBsAg), quantitative hepatitis C (HCV) antibody, quantitative human immunodeficiency virus (HIV) antibody, or treponema pallidum antibody.
