Clinical Trial Summary

This is a multicenter, randomized, double-blind, placebo and tocilizumab controlled phase II trial in RA patients to evaluate the initial efficacy, safety, pharmacokinetic, pharmacodynamic characteristics, and immunogenicity of VDJ001 in RA patients.

Description:

After screening, eligible subjects were randomly assigned in a 1:1:1:1 ratio to VDJ001 4 mg/kg group, VDJ001 6 mg/kg group, placebo group, and tocilizumab group to receive trial drug or control drug every 4 weeks. The treatment course was 12 weeks (D1, W4, W8 administration, followed up to W12).

16. Abiotic DMARDs other than MTX were administered within 28 days prior to dosing (subjects without chloroquine, hydroxychloroquine, leflunomide within 56 days prior to dosing, or no more than 28 days after standard koleenamine treatment or active carbon washout were not eligible).

17. Had received intra-articular or extra-intestinal corticosteroid therapy within 28 days prior to dosing.

18. Who had been immunized with genofin, gold thiodextrose (gold for injection), gold thiomalate (gold for injection), or oral polio vaccine within 56 days prior to administration.

19. Patients who received intravenous immunoglobulin, plasma exchange or Prosorba column within 24 weeks before screening.

20. Participated in clinical studies of other drugs within 1 month prior to screening or within 5 half-lives of other experimental drugs, whichever is longer.

21. Hepatitis B surface antigen (HBsAg) positive, or if hepatitis B core antibody (HBcAb) positive, HBV DNA test is added and HBV DNA> the lower limit of detection.

22. The laboratory test value (retest is allowed, and the last test result shall

prevail) meets any of the following conditions:

• Serum creatinine: female subjects had serum creatinine >1.4 mg per deciliter (124 µmol per liter); Serum creatinine > 1.6 mg/dL (141 µmol/L) in male subjects; ALT or AST> 1.5 times the upper limit of normal (ULN);
• Platelet count <80×109/ L;
• the WBC < 3.5 x 109 / L;
• Total bilirubin > 1.5 times ULN.
