Placebo matched to atacicept will be administered subcutaneously twice a week for initial 4 weeks, followed by once a week for subsequent 21 weeks.

Placebo matched to atacicept

Atacicept will be administered subcutaneously at a dose of 150 milligram (mg) twice a week for initial 4 weeks as loading dose, followed by 150 mg once a week for subsequent 21 weeks.

Atacicept: with loading dose

Atacicept will be administered subcutaneously at a dose of 150 mg once a week for 25 weeks.

Atacicept

Adalimumab (Humira®) will be administered subcutaneously at a dose of 40 mg every other week for 25 weeks.

Medical Responsible

The primary objective of this study is to evaluate the efficacy of atacicept compared to placebo in the treatment of signs and symptoms in a subject population with active rheumatoid arthritis (RA), inadequate response to methotrexate (MTX) and no previous exposure to anti-tumor necrosis factor alpha (anti-TNFalpha) therapy.

Atacicept in Anti-Tumor Necrosis Factor Alpha-naïve Subjects With Rheumatoid Arthritis (AUGUST II)

A Randomised, Double-blind, Placebo Controlled, Multi-centre Phase II Study of Atacicept in Anti-TNFα-naïve Patients With Moderate to Severely Active Rheumatoid Arthritis and an Inadequate Response to Methotrexate

ACR20-CRP response is defined as greater than or equal to (\>=) 20 percent (%) improvement from Baseline in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with \>=20% improvement from Baseline in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP).

ACR50-CRP response is defined as \>=50% improvement from Baseline in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with \>=50% improvement from Baseline in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP).

ACR70-CRP response is defined as \>=70% improvement from Baseline in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with \>=70% improvement from Baseline in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP).

The EULAR response criteria evaluate change in DAS28 scores represented as "good response", "moderate response", or "no response" considering both the current DAS28 score and the observed improvement from baseline. Participants were considered to have "good" or "moderate" EULAR response if at the time of assessment, their DAS28 score was less than or equal to (\<=) 5.1 and the improvement from baseline in their DAS28 score was greater than (\>) 0.6; or if at the time of assessment, their DAS28 score was \>5.1 and improvement from baseline in their DAS28 score was \>1.2.

An adverse event (AE) was defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect.

An adverse event (AE) is defined as any untoward medical occurrence in the form of signs, symptoms, abnormal laboratory findings, or diseases that emerges or worsens relative to Baseline during a clinical study with an investigational medicinal product (IMP), regardless of causal relationship and even if no IMP has been administered.

Placebo matched to atacicept was administered subcutaneously twice a week for initial 4 weeks, followed by once a week for subsequent 21 weeks.

Placebo

Atacicept was administered subcutaneously at a dose of 150 milligram (mg) twice a week for initial 4 weeks as loading dose, followed by 150 mg once a week for subsequent 21 weeks.

Atacicept 150 mg With Loading Dose

Atacicept was administered subcutaneously at a dose of 150 mg once a week for 25 weeks. Participants also received placebo matched to atacicept subcutaneously once a week during initial 4 weeks for blinding purpose (placebo injections alternating with atacicept injections).

Atacicept 150 mg Without Loading Dose

Adalimumab (Humira®) was administered subcutaneously at a dose of 40 mg every other week for 25 weeks.
