    SS-1 may improve the objective observation of dry eye.

  • Salivary scintigraphy [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    SS-1 may improve the objective observation of dry month.


Secondary Outcome Measures:
  • Oxidative stress and antioxidant capacity [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    SS-1 may reduce the oxidative stress (8-OHdG and mtDNA 4977 bp deletion) and elevate the antioxidant capacity (TAC, GSH, mtDNA copy number, SOD, GPX, CAT).

  • Quality of life (SF-36) [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    SS-1 may improve the subjective observation of quality of life.

  • Regulatory effect on cytokine [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    SS-1 may have the regulatory effect on cytokine secretion and immune function.


Other Outcome Measures:
  • Adverse effect (AE) and Adverse drug reaction(ADR) [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    Monitor the Adverse effect (AE) and Adverse drug reaction(ADR) during the SS-1 trial.

  • Liver, Kidney and Blood function monitor [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    Monitor the Liver, Kidney and Blood function (RBC, WBC, Hb, PLT, AST, ALT, BUN, Cre) of patient during the SS-1 trial.

  • Traditional Chinese medicine (TCM) tongue diagnosis [ Time Frame: 7 months ] [ Designated as safety issue: Yes ]
    To evaluate the effect of the SS-1 on the TCM tongue diagnosis before and after treatment.


Estimated Enrollment: 60
Study Start Date: February 2014
Estimated Study Completion Date: January 2016
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SS-1
SS-1 is composed of the powder of Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction with the ratio of 2:1:1. Patients take 6 gram of experiment medicine three times per day.
Drug: SS-1

The patients will be divided into two groups (A and B) at random and all of them keep the routine treatment in the rheumatology OPD. Group A patients will receive 12 weeks SS-1 treatment first, and then stop the SS-1 for 4 weeks for wash-out phase, and then receive 12weeks placebo treatment. Group B patients receive 12 weeks placebo first, and then stop the placebo treatment for 4 weeks for wash-out phase, and then receive 12weeks SS-1 treatment.

SS-1 is composed of 3 traditional Chinese herbal formula: Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction with the ratio of 2:1:1. The placebo is composed with corn starch, pigment and minimal dose of 1% SS-1. Patients in both groups take 6 gram of SS-1/Placebo three times per day.

Other Name: Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction
Placebo Comparator: Placebo
The placebo is composed of corn starch, pigment and minimal dose of 1% SS-1. Patients take 6 gram of experiment medicine three times per day.
Drug: Placebo
The placebo is composed of corn starch, pigment and minimal dose of 1% SS-1. Patients take 6 gram of experiment medicine three times per day.
Other Name: 1% SS-1

Detailed Description:

Investigators take a randomized, double-blinded, placebo-controlled, cross-over design clinical trial to evaluate the effect of Chinese herbal medicine (SS-1) on the regulation of oxidative-related cytokines and the antioxidant capacity for the Sjögren's syndrome (SJS) patients. Through the oxidative stress reduction, the quality of life and clinical manifestation will be improved. Investigators will also use a SJS cell model to elucidate the antioxidant mechanism of SS-1.

The SJS patients in this clinical trial will be screened and be referred from the out-patient department (OPD) of the Rheumatology Department of Chang Gung Memorial Hospital. The patients will be divided into two groups (A and B) at random and all of them keep the routine treatment in the rheumatology OPD. Group A patients will receive 12 weeks SS-1 treatment first and stop the SS-1 for 4 weeks to enter the wash-out phase, and then receive 12 weeks placebo treatment after the wash-out phase. Group B patients receive 12 weeks placebo first and stop the placebo treatment for 4 weeks to enter the wash-out phase, and then receive 12 weeks SS-1 treatment after the wash-out phase. SS-1 is composed of the powder of Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction with the ratio of 2:1:1 and the placebo is composed with corn starch, pigment and 1/100 SS-1. Patients in both groups take 6 gram of experiment medicine three times per day. Investigators plan to evaluate the associated parameters at the time just before treatment (V1), after treatment for 12 weeks (V2), at the end of wash-out phase (V3) and when the crossover treatment is completed (V4). Investigators use EULAR Sjogren's syndrome patient reported index, ocular surface disease index and SJS symptom questionnaire for clinical evaluation, and use the SF-36 for quality of life. And investigators use the schirmer's test, salivary scintigraphy, oxidative stress marker and related cytokine for objective observation.

Expected Results:

  1. SS-1 may improve the clinical manifestation and quality of life for the patients with Sjögren's syndrome
  2. To evaluate the effect of the Chinese medicine on the tongue diagnosis before and after treatment.
  3. SS-1 may reduce the oxidative stress (8-OHdG and mtDNA 4977 bp deletion) and elevate the antioxidant capacity (TAC, GSH, mtDNA copy number, SOD, GPX, CAT).
  4. SS-1 may have the regulatory effect on cytokine secretion and immune function.
  5. SS-1 may have the capacity of reducing the oxidative stress, elevating the antioxidant capacity and regulating the immune response in the model of submaxillary salivary gland cell line with the induction of IFN-γand IFN-α.
  6. Identification of the single herb in the SS-1 mixture that regulates oxidative stress and cytokine in the model of submaxillary salivary gland cell line, and set up of the Chinese herbs screen platform for Sjögren's syndrome.
