  • 1 Point- Unstimulated whole saliva flow rate <0.1 ml/minute
• If taking prednisone (or equivalent corticosteroid), the dose must be ≤ 10 mg/day and stable for at least 4 weeks prior to baseline visit
• If taking hydroxychloroquine, the dose must be stable for at least 12 weeks prior to baseline.
• If taking a cholinergic stimulant (e.g. pilocarpine, cevimeline), the dose must be stable for at least 4 weeks prior to baseline.
• If a male of reproductive potential, must agree to practice two highly effective forms of contraception during the study (one of which must be a barrier method) and be able to continue contraception for 20 weeks after his last dose of study agent Subject must also agree not to donate sperm up to 20 weeks after his last dose of study agent.

A subject who meets any of the following criteria is disqualified from participation in the study:

• Has a chronic or persistent infection that might be worsened by immunosuppressive treatment (e.g., HIV, hepatitis B, hepatitis C, or tuberculosis).
• History of untreated TB or positive QuantiFERON TB-Gold during screening period. If a subject has previously received an adequate course of therapy for either latent (9 months of isoniazid in a locale where rates of primary multi-drug resistant TB infection are <5%) or active TB infection, a QuantiFERON TB-Gold test need not be obtained, but a chest radiograph or other appropriate image must still be obtained if not done so within the prior 3 months.
• History of recurrent significant infections or occurrence of a serious local infection (e.g., cellulitis, abscess) or systemic infection (e.g., pneumonia, septicemia) within twelve weeks prior to Day 0.
• Active symptomatic infection within two weeks prior to Day 0.
• Receipt of live vaccine within four weeks prior to Day 0.
• History or presence of primary or secondary immunodeficiency.
• History of any life-threatening allergic reactions to pilocarpine or any components of ustekinumab. Pilocarpine will be used to stimulate salivary flow in order to assess flow rate.
• Is currently pregnant or nursing.
• Concurrent use of anticholinergic agents, such as tricyclic antidepressants, antihistamines, phenothiazines, antiparkinsonian drugs, anti-asthmatic medications, or gastrointestinal (GI) medications that cause xerostomia in more than 10% of patients.

• Treatment with any of the following within the defined period prior to the screening and Day 0 visits:

  • 12 months for rituximab
  • 24 weeks for cyclophosphamide
  • 8 weeks for azathioprine, cyclosporine, methotrexate, and mycophenolate mofetil
  • 4 weeks for intravenous immunoglobulin
  • 4 weeks for etanercept

• Prednisone (or equivalent corticosteroid) > 10 mg/day.
• A definite diagnosis of RA, SLE, systemic sclerosis, or dermatomyositis.
• A history of alcohol or substance abuse.
• A history of head and neck radiation therapy, sarcoidosis, or graft-versus-host disease.
• A history of malignancy, except for a resected basal or major squamous cell carcinoma, cervical dysplasia, or in situ cervical cancer Grade I, within the last five years.

  • Absolute neutrophil count (ANC): < 1500/mm3
  • Platelets: < 100,000/mm3
  • Hemoglobin: < 9 grams (g)/deciliter (dL)
  • Serum creatinine: ≥ 2.0 mg/dL
  • AST: > 1.5x upper limit of normal
  • ALT: > 1.5x upper limit of normal.
• A psychiatric disorder rendering the subject incapable of providing informed consent.
• Plans for foreign travel to countries other than Canada or Western Europe within the treatment period.
