Safety, Tolerability and PK of SHR1314 in axSpA

A Multicenter, Randomized, Double-Blind, Placebo-Controlled, MAD Study to Evaluation of Safety, Tolerability and PK of SHR1314 With Axial Spondyloarthritis

The main purpose of this study is to evaluate the safety, Tolerability and Pharmacokinetics (PK) of SHR1314 with axial spondyloarthritis.

This was a phase I, multicenter, double-blind, randomized, placebo-controlled study. The study originally planned to enroll 5 cohorts of 8 subjects each (N=40).

2. Have a history of back pain ≥3 months with age at onset <45 years.
3. Have active axSpA defined as BASDAI ≥4 at screening and baseline.
4. Have objective signs of inflammation by presence of elevated ESR and/or presence of elevated CRP.
5. In the past had an inadequate response to at least 1 or 2 non-steroidal anti-inflammatory drugs (NSAIDS) for duration of 4 weeks or cannot tolerate NSAIDS.
6. If taking NSAIDS be on stable dose for at least 2 weeks prior to randomization.

Exclusion Criteria:

2. Previous exposure to other biologic drug directly targeting Interleukin (IL)-17 or Interleukin (IL)-17 receptor.
3. Total ankylosis of the spine.
