E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the safety and efficacy of ABBV-154 versus placebo in subjects with PMR, who are dependent on treatment with glucocorticoids with doses of at least 5 mg/day prednisone equivalent (glucocorticoid-dependent PMR). |
|
E.2.2 | Secondary objectives of the trial |
To assess the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of ABBV-154. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Wearable Device Substudy- For collection of subject's upper limbs range of motion, daily activity, and sleep parameters. |
|
E.3 | Principal inclusion criteria |
1. Adults 50 – 80 years of age with a clinical diagnosis of PMR and fulfillment of the 2012 EULAR/ACR provisional classification criteria for PMR. 2. Following a confirmed diagnosis of PMR, subject must have shown a clinical response to prednisone (or equivalent dose) of 5 to 25 mg/day. 3. Subject must have had at least 2 episodes of unequivocal PMR flare while attempting to taper prednisone, with the dose of prednisone (or equivalent) at the time of flare ≥ 5 mg/day, prior to Baseline; the most recent flare must have been within 24 weeks of Baseline. Unequivocal PMR flare is defined as clinical signs and symptoms of PMR (shoulder and/or hip girdle pain with inflammatory stiffness, neck pain with inflammatory stiffness, or new or worsened limited range of motion of hips and/or shoulders) that resulted in an increase in glucocorticoid dose. 4. Subject must be on a stable prednisone (or equivalent) dose of 5 to 15 mg/day for ≥ 2 weeks prior to Baseline. Subjects may be on up to 25 mg/day at the Screening Visit provided that the subject is able to taper to 15 mg/day or less, with a stable dose ≥ 2 weeks prior to Baseline. 5. Subject must be willing to follow the protocol-defined glucocorticoid tapering regimen. |
|
E.4 | Principal exclusion criteria |
1. Subject must have discontinued use of immunomodulators other than prednisone (or equivalent) prior to Baseline 2. Subjects requiring > 25 mg/day of prednisone to control confirmed PMR are excluded 3. Subject must not exhibit clinical signs and symptoms of PMR (shoulder and/or hip girdle pain with inflammatory stiffness, neck pain with inflammatory stiffness, or new or worsened limited range of motion of hips and/or shoulders) within 2 weeks of Baseline |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Time to flare, where flare is defined as follows: • Presence of clinical signs and symptoms of PMR AND • Requirement to increase the glucocorticoid dose per investigator.
Clinical signs and symptoms of PMR are defined as shoulder and/or hip girdle pain with inflammatory stiffness, neck pain with inflammatory stiffness, or new or worsened limited range of motion of hips and/or shoulders that are not due to other causes |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |

E.5.2 | Secondary end point(s) |
• Achievement of flare-free state up to Week 24 • Cumulative glucocorticoid dose by 24 weeks • Change from Baseline in glucocorticoid dose at Week 24 |
