4. The subject had active disease prior to the screening visit and randomization, defined as follows: Bath AS Disease Activity Index (BASDAI) score ≥ 4 and a spinal pain score (BASDAI question 2) ≥ 4 (see Annex 6 for scoring criteria);

5. Subjects who have been treated with non-steroidal anti-inflammatory drugs (NSAIDs) and still have active disease, or who have discontinued NSAIDs due to intolerance; defined as follows: subjects must have had at least 2 cumulative inadequate clinical responses to the recommended dose (≥2 weeks of each NSAID and ≥4 weeks of total use) or intolerance to at least 2 different oral NSAIDs. Intolerance defined as discontinuation of treatment with NSAIDs due to associated adverse events (e.g., allergic reactions, gastrointestinal signs or symptoms, etc.);

6. Subjects taking treatment with NASIDs at the time of screening, requiring stable dose continuation for ≥ 2 weeks prior to randomization; no change in drug dose during the study period except for emergencies; if not taking, discontinuation for at least ≥ 2 weeks prior to randomization;

7. If subjects are enrolled in the study on a combination of methotrexate (MTX), salazosulfapyridine (SASP) and/or hydroxychloroquine (HCQ), subjects must receive a stable dose of MTX (≤25 mg/week) and/or SASP (≤3 g/day) and/or HCQ (≤400 mg/day) for at least 28 days prior to the baseline visit. A maximum of two background csDMARDs allowed in combination;

8. Subjects taking oral glucocorticoids at screening at doses ≤10 mg/day of prednisone (or equivalent doses of other glucocorticoids) that need to be continued for ≥4 weeks prior to randomization; if subjects are not taking oral glucocorticoids, they need to be off them for at least ≥4 weeks prior to randomization;

9. The subject has received ≤ 1 prior treatment with a biologic agent prior to randomization. Subjects previously treated with biologic agents must have been off ≥ 6 half-lives prior to randomization.

2. Those who have been treated with any tyrosine kinase (JAK) inhibitor (e.g. Tofacitinib, Baricitinib, Upadacitinib, etc.);etc.

4. Those who may be allergic to VC005, similar drugs or their excipients 5. Those with substance abuse or alcohol dependence 6. Subjects who, in the opinion of the investigator, may be at risk of gastrointestinal perforation during the course of the trial 7.

Subjects who have a history of major surgery, joint surgery within 6 months prior to screening or who are scheduled to have surgery during the trial 9. Female patients who are planning to become pregnant or who are pregnant or breastfeeding, or who are unable to use effective contraception throughout the trial and for 3 months after the end of the trial (see Appendix 14 for details) 10.
