Arm Intervention/treatment
Experimental: Parsaclisib Drug: Parsaclisib
Parsaclisib administered orally once daily at the protocol-defined dose.
Other Name: INCB050465

Primary Outcome Measures :
  1. Proportion of participants with a 1 point or greater change on the salivary gland ultrasound (SGUS) score for parotid and submandibular glands [ Time Frame: Week 4 and Week 12 ]
    To determine the impact of parsaclisib on salivary gland echostructure.

Secondary Outcome Measures :
  1. Change from baseline in salivary CXCL13 levels [ Time Frame: Baseline, Week 4 and Week 12 ]
    To assess the impact of parsaclisib on salivary CXCL13.

  2. Number of treatment-emergent adverse events [ Time Frame: Up to 21 weeks ]
    Adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug.

Exclusion Criteria:

  • Diagnosis of secondary SS according to the revised AECG criteria (eg, the presence of a previously diagnosed or a present diagnosis of rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, mixed connective tissue disease, polymyositis, dermatomyositis, immunoglobulin G4-related disorder, sarcoidosis, or any other defined autoimmune rheumatologic disorder).
  • Concurrent conditions and history of other diseases per protocol-defined criteria.
  • Positive test results for tuberculosis (TB) from the QuantiFERON-TB Gold test or T-spot.TB test.
  • Positive serology test results for HIV antibody, hepatitis B surface antigen, hepatitis B surface antigen antibody, HBV core antibody, or HCV (HCV antibody with positive HCV-RNA).
  • Severely impaired liver function (Child-Pugh Class C).
  • Prior or ongoing therapy with protocol-defined drugs.
  • Receipt of any live vaccine in the 30 days before screening.
  • No major surgery within 30 days before screening. Inadequate recovery from toxicity and/or complications from a major surgery before starting therapy.
  • Current alcohol or drug use that, in the opinion of the investigator, will interfere with the participant's ability to comply with the dose regimen and study evaluations.
  • Laboratory values at screening outside the protocol-defined ranges.
