Conditions
Brief summary
The purpose of this study is to evaluate the efficacy and safety of nipocalimab versus placebo in participants with moderate to severe active rheumatoid arthritis (RA).
Detailed description
RA is a chronic autoimmune inflammatory disorder of unknown etiology that occurs in approximately 1 percent (%) of the population. Nipocalimab (also referred to as JNJ-80202135 and M281) is a fully human aglycosylated immunoglobulin (Ig)G1 monoclonal antibody designed to selectively bind, saturate, and block the IgG binding site on the endogenous neonatal fragment crystallizable (Fc) receptor (FcRn). Nipocalimab has a unique mechanism of action whereby it blocks the IgG binding site on endogenous FcRn and is expected to decrease pathogenic IgG antibody concentrations. A significant involvement of pathogenic IgG antibodies has been demonstrated in autoimmune diseases including RA. The primary hypothesis is that treatment with nipocalimab intravenously (IV) every 2 weeks (q2w) is superior to placebo in participants with moderate to severe active rheumatoid arthritis (RA) as assessed by the mean change from baseline in the disease activity index score 28 using C-reactive Protein (DAS28-CRP) at Week 12. The study consists of a Screening Period (less than or equal to \[\<=\] 6 Weeks), Double-blind Treatment Period (12 Weeks), and a Safety Follow-up Period (6 Weeks). Key safety assessments will include adverse events (AEs), serious adverse events (SAEs), adverse events of special interests (AESIs), clinical laboratory safety tests (hematology, chemistry, and lipid profile), vital signs, and physical examination. The total duration of the study is up to 24 weeks.
Interventions
Placebo infusion will be administered intravenously.
Nipocalimab infusions will be administered intravenously.

The DAS28 is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity, and C-reactive protein (CRP; in milligrams per liter \[mg/L\]). The set of 28 joint count was based on evaluation of the shoulder, elbow, wrist, metacarpophalangeal (MCP) MCP1 to MCP5, proximal interphalangeal (PIP) PIP1 to PIP5 joints of both the upper right extremity and the upper left extremity as well as the knee joints of lower right and lower left extremities. Score on the DAS28 ranged from 0 to 10, where higher scores indicated more disease activity. Negative changes from baseline indicated improvement of arthritis. |

TEAEs were defined as any AE occurring at or after the initial administration of study intervention through the safety follow-up visit (8 weeks after the last administration of study intervention).
Time frame: From Week 0 up to 8 weeks post last dose at Week 10 (up to Week 18)
Population: The safety analysis set included all randomized participants who received at least 1 dose (partial or complete) of any study intervention.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Group 1: Placebo | Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) | 60.0 Percentage of Participants |
| Group 2: Nipocalimab | Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) | 81.8 Percentage of Participants |
Percentage of Participants With Treatment-emergent Serious Adverse Events (TESAEs)
Percentage of participants with TESAEs were reported. An AE was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. A SAE was any untoward medical occurrence at any dose that: resulted in death, was life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/ incapacity, or resulted in congenital anomaly/birth defect. TESAEs were defined as any SAE occurring at or after the initial administration of study intervention through the safety follow-up visit (8 weeks after the last administration of study intervention).
Time frame: From Week 0 up to 8 weeks post last dose at Week 10 (up to Week 18)
Population: The safety analysis set included all randomized participants who received at least 1 dose (partial or complete) of any study intervention.
