Detailed Description

Cyclophosphamide (CPA) has been one of the most successful therapies for severe Systemic lupus erythematosus (SLE). However, cyclophosphamide can cause severe side effects, including bone marrow suppression, infection, gastrointestinal reaction, hemorrhagic cystitis, and the etc. Significant variation in efficacy and toxicity of CPA has been observed. Since the development of applicable therapeutic drug monitoring (TDM) of cyclophosphamide has been reported, it will help to improve the efficacy and reduce toxicities in SLE treatment. However, the TDM is a passive strategy which usually lags behind the appearance of toxicities. Therefore，it is especially crucial to give individuals genotype-based personal prescription of cyclophosphamide in order to gain the most effective therapies. Thus, the purpose of this study is to compare the genotype-based personal prescription of cyclophosphamide with the traditional prescription, in order to verify the efficacy of the genotype-based personal prescription.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 60 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • The American College of Rheumatology established eleven criteria in 1982,which were revised in 1997 as a classificatory instrument to operationalise the definition of SLE in clinical trials.

    1. Malar rash (rash on cheeks).
    2. Discoid rash (red, scaly patches on skin that cause scarring).
    3. Serositis: Pleurisy (inflammation of the membrane around the lungs) or pericarditis (inflammation of the membrane around the heart).
    4. Oral ulcers (includes oral or nasopharyngeal ulcers).
    5. Arthritis: nonerosive arthritis of two or more peripheral joints, with tenderness, swelling, or effusion.
    6. Photosensitivity (exposure to ultraviolet light causes rash, or other symptoms of SLE flareups).
    7. Blood-hematologic disorder-hemolytic anemia (low red blood cell count) or leukopenia (white blood cell count<4000/µl), lymphopenia (<1500/µl) or thrombocytopenia (<100000/µl) in the absence of offending drug. Hypocomplementemia is also seen, due to either consumption of C3 and C4 by immune complex-induced inflammation or to congenitally complement deficiency, which may predispose to SLE.
    8. Renal disorder: More than 0.5 g per day protein in urine or cellular casts seen in urine under a microscope.
    9. Antinuclear antibody test positive.
    10. Immunologic disorder: Positive anti-Smith, anti-ds DNA, antiphospholipid antibody, and/or false positive serological test for syphilis. Presence of anti-ss DNA in 70% of cases (though also positive with rheumatic disease and healthy persons).
    11. Neurologic disorder: Seizures or psychosis. For the purpose of identifying patients for clinical studies, a person has SLE if any 4 out of 11 symptoms are present simultaneously or serially on two separate occasions. In the meantime, the case has one of the following conditions or more;
    1. HIV (-);
    2. Signed the informed consent;
    3. Taking contraceptive measures during treatment period.

Exclusion Criteria:

  • Poor compliance;
  • With lupus mental damage complication, occurrence of epilepsy or unable to express subjective symptoms during the observation period.
  • Taking drugs that affect cytochrome P450 2B6, cytochrome P450 3A4 and cytochrome P450 2C19, except corticosteroids.
  • Abnormal liver function.
