About this study

Official title: Evaluation of the Efficacy and the Mechanism of Chinese Herbal Formula SS-1 for Sjögren's Syndrome - A Randomized Control Trial

To evaluate the efficacy of Chinese herbal medicine (SS-1) for the Sjögren's syndrome (SJS) patients.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SS-1Drug

    Also called Gan-Lu-Yin, Sang-Ju-Yin and Xuefu-Zhuyu-Decoction

    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.

  • PlaceboDrug

    Also called 1% SS-1

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ocular surface disease index (OSDI)

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

    Measured: 7 months

  2. EULAR Sjogren's syndrome patient reported index (ESSPRI)

    SS-1 may improve the subjective sensation of dry, pain and fatigue.

    Measured: 7 months

  3. SJS symptoms Questionnaire

    SS-1 may improve the subjective sensation of dry month.

    Measured: 7 months

  4. Schirmer's test

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

    Measured: 7 months

  5. Salivary scintigraphy

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

    Measured: 7 months

Secondary outcomes (3)
  1. Oxidative stress and antioxidant capacity

    SS-1 may reduce the oxidative stress and elevate the antioxidant capacity

    Measured: 7 months

  2. Quality of life (SF-36)

    SS-1 may improve the subjective observation of quality of life.

    Measured: 7 months

  3. Regulatory effect on cytokine

    SS-1 may have the regulatory effect on cytokine secretion and immune function.

    Measured: 7 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SS-1 in people with Sjögren's Syndrome, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hen-Hong Chang, M.D., Ph.D. (+886-3196200 ext. 2677, tcmchh55@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ocular surface disease index (OSDI) (time frame: 7 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2016.
