Primary Sjogren's syndrome (pSS) is an autoimmune disorder characterized by keratoconjunctivitis sicca and xerostomia. In addition, various extraglandular manifestations may develop. Several immunomodulating agents have been attempted in the treatment of pSS without achieving satisfactory results. Currently, there is no approved systemic treatment for pSS.
Mycophenolic acid (MPA) is a selective inhibitor of inosine-monophosphate-dehydrogenase which leads to inhibition of the de novo pathway of nucleotide synthesis. The antiproliferative effect of MPA mainly affects activated T- and B-lymphocytes because the proliferation of these cells is critically dependent on the de novo purine synthesis compared to other eukaryotic cells. Since these lymphocytes have been suggested to play a pivotal role in the inflammation and immunopathogenesis of pSS, mycophenolate-sodium might be a promising agent in the treatment of pSS.
We perform a single-centre, open-label pilot trial with Mycophenolate sodium in pSS.
|Condition or disease||Intervention/treatment||Phase|
|Primary Sjogren's Syndrome||Drug: Mycophenolate sodium||Phase 1|
Mycophenolic acid containing compounds such as mycophenolate mofetil and enteric coated mycophenolate sodium are immunosuppressive drugs approved for the prevention of transplant rejection. Mycophenolate mofetil (MMF) is an effective treatment in systemic lupus erythematosus and other autoimmune diseases.
MMF has been used as maintenance therapy after treatment with rituximab (anti-CD20 antibody) in a pSS patient. We have reported a case of successful treatment with MMF in pSS with vasculitis.
The recent observations and the immunosuppressive effect of MPA in other autoimmune diseases led us to evaluate the efficacy and safety of MPA treatment in patients with pSS refractory to other immunosuppressive agents.
The observation period will be 6 months. At baseline, after 3, and after 6 months we examine the clinical status including glandular function tests as well as different laboratory parameters associated with pSS. In addition subjective parameters will be determined on the basis of different questionnaires.

- Drug: Mycophenolate sodium
Medical treatment is initiated with one tablet of 360 mg mycophenolate sodium orally per day for eligible patient. The dosage will be increased weekly by 360 mg up to a maximum stable dose of 1440mg daily. In patients not well tolerating the drug the dosage can be reduced to 720 mg per day.Other Name: Myfortic
- Efficacy of mycophenolate sodium for sicca syndrome and changes in laboratory values associated with the disease [ Time Frame: Basline, week 12 and week 24 ]
- Safety of mycophenolate sodium in patients with primary Sjogren's syndrome: Clinical examination, full blood count, renal function tests, liver function tests [ Time Frame: basline, after week 4, 12, and week 24 ]
