Brief Summary:
This is an open-label pilot study of tocilizumab (TCZ) 162 mg weekly administered subcutaneously for 52 weeks in combination with 8 weeks of oral prednisone.

Condition or disease Intervention/treatment Phase
Giant Cell Arteritis Drug: Tocilizumab Drug: Prednisone Phase 4

Detailed Description:

This is a single center, open label study that will assess the efficacy and safety of 52 weeks of tocilizumab (TCZ) in combination with 8-weeks of prednisone in 30 patients with active giant cell arteritis (GCA). Active disease is defined as signs and/or symptoms of GCA plus increased inflammatory markers (e.g., erythrosedimentation rate [ESR] and/or C-reactive protein [CRP]).

The study will enroll subjects with new onset and with relapsing/refractory GCA, and consist of a screening phase (up to 6 weeks), a treatment phase (52 weeks) and a safety follow up phase (4 weeks).

The primary endpoint of the study, sustained remission, will be assessed at week 52.

The definition of sustained remission contains 3 elements:

  1. Absence of clinical signs and symptoms of active GCA along with the normalization of the ESR (< 40 mm/hour) and CRP (< 10 mg/L).
  2. Completion of the pre-specified prednisone taper protocol
  3. Absence of disease flare (relapse) since the induction of remission by week 8.

Disease flare is defined as the re-appearance of unequivocal signs or symptoms of active GCA (with or without elevation of ESR and/or CRP) or the elevation of the ESR and/or CRP that is thought to be due to active GCA and that requires escape therapy.

Layout table for eligibility information
Ages Eligible for Study:   50 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Ability and willingness to provide written informed consent and to comply with the study protocol
  2. Diagnosis of GCA classified per the following criteria:

    • Age 50 years or older

    AND at least one of the following:

    • Unequivocal cranial symptoms of GCA (new-onset localized headache, scalp tenderness, temporal artery tenderness or decreased pulsation, ischemia-related vision loss, or otherwise unexplained mouth or jaw pain upon mastication)
    • Symptoms of polymyalgia rheumatica (PMR), defined as shoulder and / or hip girdle pain associated with inflammatory morning stiffness

    AND at least one of the following:

    • Cranial artery biopsy revealing features of GCA (e.g., mononuclear cell infiltration or granulomatous inflammation).
    • Evidence of large-vessel vasculitis by angiography or cross-sectional imaging study such as Image result for magnetic resonance angiogram (MRA), Computed tomography angiography (CTA) , or Image result for positron emission tomography (PET) and computed tomography (CT) (PET-CT)
    • Ultrasound demonstration of features of GCA in a cranial artery.
  3. New-onset or relapsing/refractory active disease defined as follows:

    • New onset: diagnosis of GCA within 6 weeks of baseline visit
    • Relapsing/refractory: diagnosis of GCA > 6 weeks before baseline visit

AND

• Active GCA within 6 weeks of baseline visit defined as the presence of clinical signs and symptoms [cranial or PMR] and erythrocyte sedimentation rate (ESR) ≥ 30 mm/hour or C-reactive protein (CRP) ≥ 10 mg/L)

Exclusion Criteria:

  1. General exclusion criteria

    • Major surgery within 8 weeks prior to screening or planned major surgery within 12 months after randomization
    • Transplanted organs (except corneal transplant performed more than 3 months prior to screening)
    • Major ischemic event, unrelated to GCA, within 12 weeks of screening
  2. Exclusions related to prior or concomitant therapy*

    • Treatment with any investigational agent within 12 weeks (or 5 half-lives of the investigational drug, whichever is longer) of screening
    • Previous treatment with cell-depleting therapies, including investigational agents, including but not limited to Campath (alemtuzumab), anti-CD4 (cluster of differentiation 4), anti-CD5, anti-CD3, anti-CD19, and anti-CD20

    • Treatment with cyclosporine A, azathioprine, cyclophosphamide or Mycophenolate mofetil (MMF) within 4 weeks of baseline. Patients on methotrexate at screening will require discontinuation of this agent prior to baseline visit.
