About
The investigators had observed that baricitinib was effective and safe in active pSS patients in a pilot study. So the investigators plan to conduct a multi-center, prospective, open-label, randomized study to compare the efficacy of baricitinib + hydroxychloroquine (HCQ) with HCQ alone in active pSS patients. The participants will be randomized (1:2) to receive HCQ (200mg twice a day) or baricitinib (4mg per day) + HCQ (200mg twice a day) until week 24. The primary endpoint is the ESSDAI and ESSPRI response (define as an improvement of ESSDAI at least three points, and ESSPRI at least one point or 15%) at 12 weeks. According to an expected response rate of 70% in baricitinib + HCQ group and 30% in HCQ group, the investigators will involve approximately 87 participants (29:58) with 20% drop out rate. The investigators will switch HCQ to baricitinib + HCQ if the participants has no response at 12 weeks. The investigators hypothesized that baricitinib was effective and safe in active pSS patients.
Full description
All participants will be divided into HCQ group or HCQ + baricitinib group randomly. On the basis of the HCQ treatment before, the participants in the latter group will be given baricitinib 4mg once a day.
The participants will come to visit at week 0, 4, 8, 12, 16, 20 and 24. The final evaluation will be at week 24. The participants who has no response to HCQ treatment alone at week 12 will be switched to baricitinib + HCQ group and treated with baricitinib 4mg per day until the end of the study (week 24).
Baseline information included demographics, SS duration, clinical manifestations, laboratory parameters, current medications, and disease activity. Laboratory tests, including complete blood counts, urinalysis, liver and renal function tests, ESR, and IgG test were performed at each visit. Disease activity was assessed using the ESSDAI, EULAR primary SS patient reported index (ESSPRI), and physician global assessment (PGA) scores.

Patients who are receiving thyroxine as replacement therapy may participate in the study, provided stable therapy has been administered for ≥12 weeks and TSH is within the laboratory's reference range. Patients who have TSH marginally outside the laboratory's normal reference range and are receiving stable thyroxine replacement therapy may participate if the treating physician has documented that the thyroxine replacement therapy is adequate for the patient.

- QuantiFERON®-TB Gold test or T-SPOT®.TB test (as available and if compliant with local TB guidelines) may be used instead of the PPD test. Patients are excluded from the study if the test is not negative and there is clinical evidence of active TB.
Exception: patients with a history of active TB who have documented evidence of appropriate treatment, have no history of re-exposure since their treatment was completed, have no clinical features of active TB, and have a screening chest x-ray with no evidence of active TB may be enrolled if other entry criteria met. Such patients would not be required to undergo the protocol-specific TB testing for PPD, QuantiFERON®-TB Gold test, or T-SPOT®.TB test but must have a chest x-ray at screening (i.e., chest imaging performed within the past 6 months will not be accepted).

If the test results are not negative, the patient will be considered to have latent TB (for purposes of this study); or
- QuantiFERON®-TB Gold test or T- SPOT®.TB test (as available and if compliant with local TB guidelines) may be used instead of the PPD test. If the test results are positive, the patient will be considered to have latent TB. If the test is not negative, the test may be repeated once within approximately 2 weeks of the initial value. If the repeat test results are again not negative, the patient will be considered to have latent TB (for purposes of this study).

Such patients would not be required to undergo the protocol-specific TB testing for PPD, QuantiFERON®-TB Gold test, or T-SPOT®.TB test but must have a chest x-ray at screening (i.e., chest imaging performed within the past 6 months will not be accepted).
