Descripción detallada
The study will have 3 treatment arms each with 10 patients who have demonstrated T cell immunity to CII and have an in vitro response to APL A12 at the screening visit. Patients will be randomized to one of the 3 treatment arms. Each of the 3 treatments will be given for 16 weeks.
In keeping with a sequential dose escalation strategy, the originally proposed randomization scheme will be modified so that subjects will be randomized to receive either the lowest dose (30 mg) or placebo (Block 1), followed by the next dose (50 mg) or placebo (Block 2). We will begin with the lowest dose (30 g/day) and enroll 6 to receive 30 g/day APL A12 and 2 to receive placebo for 16 weeks. Results will be reported to the Data Monitoring Committee (DMC) for a decision to proceed to the next block based on indications of safety. If this dose does not cause adverse events or toxicity or worsens RA, we will proceed to enroll patients to receive 30 ug, or 50 g/day APL A12 or placebo for 16 weeks. A total of 32 subjects will be randomized to obtain 24 subjects who complete the study. Recruitment was difficult. Only 22 patients were randomized. There were not enough 50mcg patients enrolled so 2 treatment groups was analyzed. Arm 1 included 30 and 50 mcg and Arm 2 represents the patients that received placebo.

Descripción
Inclusion Criteria:
Patients must meet the following criteria for participation in the study.
- Male or female; age > 18 years.
- American College of Rheumatology (ACR) 1988 revised criteria for rheumatoid arthritis.
- Onset of disease age 16 or older.
- Onset of disease at least 3 months prior to enrollment.
- RA patients ages 18-85 with RA of 3 month duration which in the opinion of the examining rheumatologist is "clinically stable" and will likely not require adjustment of doses of Disease-modifying antirheumatic drugs (DMARDS), NSAIDS, prednisone, anti-tumor necrosis factor (anti-TNF) alpha therapies for the 16 weeks of the treatment phase of the study.
- Patients must agree to discontinue all "herbal remedies" as described in this protocol.
- Women of childbearing age will be advised to use effective means of contraception for the treatment phase of the trial and for 90 days thereafter. They must have a negative urine pregnancy test at the randomization visit. (Required by the FDA.)
- Men will be advised to use effective means of contraception for the treatment phase of the trial and for 90 days thereafter. (Required by the FDA.)
- Crohn's Disease Activity Index (CDAI) less than or equal to 30 at the baseline visit.
- Patients with a past history of malignant neoplasm will be eligible if they are 1 or greater years with no recurrence of malignant neoplasm.
Exclusion Criteria:
- Inability to render an informed consent in accordance with institutional guidelines.
- Participation in another clinical research study involving the evaluation of another investigational drug within 90 days of entry into this study.
- RA patients on >7.5 mg prednisone a day.
- RA patients with intra-articular corticosteroid injections during the previous 30 days.
- Concurrent serious medical condition which in the opinion of the investigator makes the patient inappropriate for the study. Hepatitis B abd/or C patients with inactive disease (as determined by PI) will be enrolled.
- Positive urine pregnancy test
- Age 85 years or greater.
- Use of "fish oil" within the previous 4 weeks of the baseline visit.
- Therapy consisting of auranofin or cyclophosphamide (all other DMARDs are allowed).
- Previous autologous or heterologous stem cell transplantation.
- Active malignant neoplasm or past treatment for malignant neoplasm 1 year from screening visit.
- Use of oral CII within the past 1 year. (Since oral tolerance is short-lived, we will permit patients in the study who have been off oral CII for > 1 year)
- Diabetes requiring insulin or on oral medications must be well managed at baseline. Adjustment of insulin or on oral medications will be allowed during the study.
- Serum creatinine 2.0 mcg/dL.
- An 1(II) IFN value <100% of the PBS IFN value within 1 month or less prior to the baseline and less than 25% reduction in APL A12 + 1(II) IFN from 1(II) IFN concentration.
- CDAI > 30 at the baseline visit.

Experimental: Arm 1
The study will have 3 treatment arms each with 10-12 patients who have demonstrated T cell immunity to CII and have an in vitro response to APL A12 at the screening visit. Patients will be randomized to one of the 2 treatment arms (30 micrograms APL A12 or placebo). Each of the 2 treatments will be given for 16 weeks. Intervention: Drug treatment will be stopped or interrupted if indicated and medical care will be given as appropriate.

Experimental: Arm 3
Block 3 (Arm 3) will include placebo and both doses of APL/A12 to ensure 10-12 patients are enrolled in each arm ( total of approximately 32 subjects) so we will have 24 subjects who complete the 16 weeks of study treatment. Arms 2 and 3 will run simultaneously. Intervention: Drug treatment will be stopped or interrupted if indicated. |
