Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of ABT-494 in combination with a corticosteroid taper regimen compared to placebo in combination with a corticosteroid taper regimen, as measured by the proportion of subjects in sustained remission at Week 52, and to assess the safety and tolerability of ABT-494 in subjects with GCA in Period 1. ;Secondary Objective: To evaluate the safety and efficacy of continuing versus withdrawing ABT-494 in maintaining remission in subjects who achieved remission in Period 1.;Primary end point(s): The proportion of subjects achieving sustained remission at Week 52 as defined as: • Absence of GCA signs and symptoms from Week 12 through Week 52 • Adherence to the protocol defined corticosteroid taper regimen;Timepoint(s) of evaluation of this end point: Week 12-52 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The key secondary endpoints include: 1. Proportion of subjects achieving sustained complete remission from Week 12 through Week 52. Sustained complete remission is defined as having achieved all of the following: - Absence of GCA signs and symptoms from Week 12 through Week 52; - Normalization of erythrocyte sedimentation rate ([ESR] to 30 mm/hr attributable to GCA, AND requiring an increase in CS dose. 4. Proportion of subjects who experience at least 1 disease flare through Week 52. 5. Proportion of subjects in complete remission at Week 52. Complete remission is defined as having achieved all of the following: - Absence of GCA signs and symptoms; - Normalization of ESR to < 30 mm/hr; - Normalization of hsCRP to < 1 mg/dL; and - Adherence to the protocol-defined CS taper regimen. 6. Proportion of subjects in complete remission at Week 24. 7. Change from Baseline in the 36-item Short Form Quality of Life Questionnaire (SF-36) Physical Component Score (PCS) at Week 52. 8. Number of disease flares per subject during Period 1. • Change from Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at Week 52. • Assessment of Treatment Satisfaction Questionnaire for Medication (TSQM) patient global satisfaction subscale at Week 52. • Rate of CS-related AEs.;Timepoint(s) of evaluation of this end point: Week 12 to 52 | — |
