Brief Summary

This is a randomized, vehicle controlled, double-blind, repeat dose comparative study in patients with rheumatoid arthritis (RA) under management with DMARDs and with persistent disease activity. The goal of this study is to evaluate the safety, tolerability and pharmacokinetics of 6 weekly repeat doses of ORTD-1.

Inclusion Criteria
  • ≥18 years of age or older, males or females.

  • Diagnosed rheumatoid arthritis per the American Rheumatism Association 1987 classification criteria of at least 6 months duration.

  • Disease activity defined as:

    • erythrocyte sedimentation rate (ESR) > 24 mm or serum C-reactive protein level ≥ 1.2 times (X) the upper limit of normal (ULN), and
    • DAS28-CRP score ≥ 2.6 and < 5.1
  • Current regimen of DMARDs that may include methotrexate, sulfasalazine, hydroxychloroquine, leflunomide and/or azathioprine, alone or in combination.

  • No change in DMARD dose(s) within 4 weeks prior to Screening.

  • May be receiving a stable regimen (of at least 4 weeks duration) of concomitant NSAIDs.

  • Women of child-bearing potential (WOCBP), defined as a sexually mature woman not surgically sterilized, or not post-menopausal for at least 12 consecutive months. Female subjects must:

    • Not be lactating; not be pregnant upon enrollment.
    • Agree to use highly effective methods of birth control throughout the study. Highly effective methods of contraception include combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation by oral, intravaginal, or transdermal administration; progestogen-only hormonal contraception associated with inhibition of ovulation by oral, injectable, or implantable administration; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; partner vasectomy; or total abstinence (only if total abstinence is an established method and lifestyle of the subject).
    • Patients already using hormonal contraception at the time of screening will be eligible but will not initiate hormonal contraception in order to participate in the study.
    • Agree to use highly effective methods of birth control for at least 6 months after the last dose of investigational product.
  • Male subjects must refrain from donating sperm or fathering a child during the study.

  • Male subjects must use barrier contraception throughout the course of the study.

  • Signed and dated informed consent.

Exclusion Criteria
  • Prior therapy with any biologic therapeutic within 3 months prior to enrollment, or in the case of Rituxan (rituximab), this period must be at least 12 months.
  • History of or current clinical fibromyalgia or Juvenile Idiopathic Arthritis (JIA).
  • Positive diagnosis of SLE.
  • Patients with Type 1 or Type 2 Diabetes Mellitus.
  • Patients with psoriasis.
  • Patients with skin condition(s) or visible abnormalities at or near potential sites of injection (right and left abdomen; right and left thigh) that could mask the assessment of safety.
  • Acute illness including current or chronic infections requiring antibiotics, or symptoms of a resolving illness, within 2 weeks prior to study.
  • Any investigational drug within 3 months prior to study.
  • Patients may not be receiving systemic corticosteroid therapy with the exception of inhaled corticosteroids for the treatment of asthma.
  • Any clinically relevant abnormality as assessed by the Investigator, on screening history, physical exam, clinical laboratory, chest X-ray, or ECG, other than values consistent with rheumatoid arthritis, with the exception that liver function tests (ALP, ALT, AST) may be up to 1.5 times (X) the upper limit of normal (ULN).
  • Positive serological test for HCV, HBsAg, HBcAg, HIV.
  • QuantiFERON-positive patients may be enrolled with documented evidence that they have completed a prescribed course of antituberculous therapy.
  • History of cardiovascular disease with New York Heart Association (NYHA) functional class II or greater; or history of stroke, or uncontrolled hypertension.
  • History of lymphoproliferative disease, or organ allograft.
  • Pregnancy or lactation, or WOCBP not currently using contraceptives or male partners of WOCBP not currently using contraceptives.
  • History of cancer (except for in situ cancer, or limited stage cancer of the cervix, head and neck (squamous cell), thyroid, or skin (non-melanomatous) curatively treated with no sign of disease for > 5 years).
  • Any physical or psychological condition that might prevent complete participation in the study, in the view of the investigator.

Primary Outcome Measures
NameTimeMethod
Safety and Tolerability of ORTD-1 measured by the number of patients with adverse events10 weeks

Safety will be assessed throughout the duration of the study (weeks 1 through 10) by monitoring of adverse events.

Secondary Outcome Measures
NameTimeMethod
Immunogenicity by measurement of anti-drug antibodiesWeeks 1, 3, 5, and 10

Immunogenicity is the measurement of anti-drug (ORTD-1) antibodies (ADA) in serum. ADA samples will be analyzed from the change in baseline (Visit 1) using descriptive statistics (mean, median, range and standard deviation).

Cmax of ORTD-1Week 1 through week 6

Cmax (maximum plasma concentration) will be measured using the arithmetic mean, standard deviation (SD), coefficient of variation (CV) (%), median, minimum, and maximum.

Serum concentration of ORTD-1 from baseline10 weeks

Serum concentration will be measured from the change in baseline (Visit 1) using descriptive statistics (mean, median, range and standard deviation).

Tmax of ORTD-1Week 1 through week 6

Tmax (time of maximum plasma concentration) will be measured using the arithmetic mean, standard deviation (SD), coefficient of variation (CV) (%), median, minimum, and maximum.
