This Phase 1b/2a study will evaluate safety, tolerability pharmacokinetics (PK) and pharmacodynamics (PD) of brodalumab when administered in multiple subcutaneous (SC) and intravenous (IV) doses in patients with active rheumatoid arthritis (RA) in combination with a stable dose of disease modulating anti-rheumatic drugs (DMARDs). Part A is dose escalation (to assess safety & tolerability), and Part B is dose expansion (to assess clinical efficacy) at the highest tolerated dose level of brodalumab from Part A.

Age group | 18 Years to 70 Years |
Eligibility | Inclusion Criteria: - Male or female between 18 to 70 years of age, inclusive at the time of screening - Diagnosed with RA as determined by meeting 1987 American College of Rheumatology (ACR) classification criteria - Active RA defined as = 6 swollen joints (out of 66 joints examined) and = 8 tender/painful joints (out of 68 joints examined) and at least 1 of the following: - Erythrocyte sedimentation rate (ESR) = 28 mm, or - C-reactive protein (CRP) > 15 mg/L, or - Morning stiffness > 45 minutes (applicable to subjects in Part A ONLY) - Duration of RA for at least 6 months - Currently taking methotrexate (MTX) consecutively for = 12 weeks and on a stable dose of oral or SC MTX at 15-25 mg weekly for = 4 weeks at day -1. A lower MTX dose is acceptable if it is the highest tolerated dose, however, toxicity documentation by the Investigator is required. All subjects will take folic acid to minimize toxicity, according to local guidelines. - Additional Inclusion Criteria Apply Exclusion Criteria: - History or evidence of a clinically significant disorder other than RA (including but not limited to cardiopulmonary, oncologic, renal, metabolic, hematologic or psychiatric), condition or disease that, in the opinion of the Investigator and Amgen physician would pose a risk to subject safety or interfere with the study evaluation, procedures or completion - Uncontrolled, clinically significant systemic disease other than RA such as diabetes mellitus, liver disease, asthma, cardiovascular disease or hypertension - Malignancy within 5 years (except successfully treated in situ cervical cancer or squamous or basal cell carcinoma of the skin) - Presence of a serious or chronic infections - Subject (male or female) is not willing to use highly effective contraception, defined as a double barrier method (ie, spermicidal jelly and condom, or condom and diaphragm) during treatment and up to end of study - Additional Exclusion Criteria Apply |

Primary | Number of Participants With Treatment-emergent Adverse Events | An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment, including any such occurrence (eg, sign, symptom, or diagnosis) or worsening of a pre-existing medical condition. A serious adverse event was defined as an adverse event that was fatal; was life threatening; required in-patient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect; or other significant medical hazard. |
From first dose of study drug up to end of study (week 19). | |
Primary | Number of Participants With Clinically Significant Changes in Safety Laboratory Tests | The investigator reviewed laboratory test results and determined whether an abnormal value in an individual study participant represented a change from prestudy values and determined if changes were clinically significant. The number of participants with clinically significant changes in lab values at any time during the study is reported. | Blood samples were taken on days 2, 8, 15, 29, 43, 57, 71, 85, 106, and 127. | |
Primary | Number of Participants With Clinically Significant Changes in Physical Examination Findings, Vital Signs, or Electrocardiogram Findings | From first dose of study drug up to 4 weeks after last dose; 14 weeks for Cohorts 1, 2, and 3 and 8 weeks for Cohorts 5 and 6. | ||
Primary | Number of Participants With Anti-brodalumab Antibodies | Samples were tested in a validated immunoassay for the presence of anti-brodalumab binding antibodies. Samples found to be positive for binding antibodies were further tested using a validated cell-based bioassay to determine if the antibodies were able to neutralize the activity of brodalumab. | Days 1 (pre-dose), 29 (pre-dose), 85, and 127 | |
Secondary | Time to Maximum Concentration of Brodalumab After Single and Multiple Subcutaneous Doses | After first dose on days 1 (pre-dose and 4 hours post-dose), 2, 3, 5, 8, 11, and 15 (pre-dose), and after last dose on days 71 (pre-dose and 4 hours post-dose), 72, 73, 75, 78, 81, 85, 106 and 127. | ||
Secondary | Maximum Concentration of Brodalumab After Single and Multiple Subcutaneous Doses | After first dose on days 1 (pre-dose and 4 hours post-dose), 2, 3, 5, 8, 11, and 15 (pre-dose), and after last dose on days 71 (pre-dose and 4 hours post-dose), 72, 73, 75, 78, 81, 85, 106 and 127. | ||
Secondary | Area Under the Concentration-time Curve From Time Zero to the Time of the Final Quantifiable Sample (AUC0-t) for Brodalumab After Single and Multiple Subcutaneous Doses | After first dose on days 1 (pre-dose and 4 hours post-dose), 2, 3, 5, 8, 11, and 15 (pre-dose), and after last dose on days 71 (pre-dose and 4 hours post-dose), 72, 73, 75, 78, 81, 85, 106 and 127. | ||
Secondary | Accumulation Ratio for Brodalumab After Subcutaneous Dosing | Accumulation was measured by AUC0-t, last dose / AUC0-t, first dose). | After first dose on days 1 (pre-dose and 4 hours post-dose), 2, 3, 5, 8, 11, and 15 (pre-dose), and after last dose on days 71 (pre-dose and 4 hours post-dose), 72, 73, 75, 78, 81, 85, 106 and 127. | |
Secondary | Time to Maximum Concentration of Brodalumab After Single and Multiple Intravenous Doses | After first dose on days 1 (pre-dose and 0.5 and 4 hours post-dose), 2, 3, 5, 8, 11, and 15, and after last dose on days 29 (pre-dose and 0.5 and 4 hours post-dose), 30, 31, 33, 36, 39, 43, 57, 85, 106 and 127. | ||
Secondary | Maximum Concentration of Brodalumab After Single and Multiple Intravenous Doses | After first dose on days 1 (pre-dose and 0.5 and 4 hours post-dose), 2, 3, 5, 8, 11, and 15, and after last dose on days 29 (pre-dose and 0.5 and 4 hours post-dose), 30, 31, 33, 36, 39, 43, 57, 85, 106 and 127. | ||
