• 1 other identifier: BAT-1806-002-CR
• Study Type: interventional
• Target: 621
• Locations: 1 country
• Sites: 1

Brief Summary

This is a Phase 3, multicenter, multinational, randomized, double-blind, parallel-group, active-control study to compare efficacy, safety, immunogenicity, and PK of BAT1806 compared with RoActemra in subjects with RA that is inadequately controlled by MTX. The study is composed of a ≤ 28-day screening period, a 24-week initial treatment period (TP1), a 24 week secondary treatment period (TP2), and an extra 4-week follow-up period.

Conditions

Rheumatoid Arthritis

Outcome Measures

Primary Outcomes (1)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male or female subjects 18 years of age or older who fulfil the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010 revised classification criteria for RA diagnosis for at least 6 months before screening, based on the medical history record.
• Subject presents with active RA, as defined by:
• ≥ 6 out of 68 tender joints (at screening and randomization) AND
• ≥ 6 out of 66 swollen joints (at screening and randomization) AND
• Serum C-reactive protein (CRP) \> upper limit of normal (ULN) value or erythrocyte sedimentation rate (ESR) ≥ 28 mm/hour at screening.
• Subjects are eligible if they have received not more than 2 biological agents other than interleukin-6 inhibitors or targeted synthetic DMARDs (eg, tofacitinib) in total for RA treatment.
• Female subjects of childbearing potential and male subjects with a female partner of childbearing potential must be willing to take reliable contraceptive precautions throughout the study period and continuing for at least 3 months after the last dose of study drug. Reliable methods of contraception include: intrauterine device, hormonal contraceptives (eg, oral, patch, or injectable), male vasectomy (if vasectomy was medically confirmed), a barrier protection method (eg, condom or diaphragm) in association with spermicide cream, foam, or gel. Abstinence from heterosexual intercourses is accepted when this is the usual lifestyle of the subject and must be continued for at least 3 months after the last dose of study drug. A female subject is considered not of child-bearing potential when postmenopausal (at least 12 consecutive months without menses without an alternative medical cause) or surgically sterilized (bilateral tubal ligation, bilateral oophorectomy with or without hysterectomy).
• If female of childbearing potential, subject should have a negative pregnancy test result at screening and baseline visit.
• Subjects must be willing to provide written consent and to comply with the requirements of the study protocol.

You may not qualify if:

• Has RA of ACR functional class IV or is wheelchair/bed bound.
• Known hypersensitivity to tocilizumab or to study treatment excipients.
• Subject has received any cell-depleting therapy (eg, rituximab) ≤ 12 months prior to randomization.
• Subject has been treated with an investigational drug other than those prohibited or device ≤ 8 weeks or 5 half-lives of the drug (whichever is longer) prior to randomization.
• Subject has undergone joint surgery ≤ 12 weeks prior to randomization (on any joint to be assessed during the study) or has any surgery planned during the study.
• Evidence of malignancy, lung infection, or abnormalities suggestive of active tuberculosis (TB) on chest radiography performed within 12 weeks prior to the Screening Visit or during the screening period.
• Any recurrent bacterial, fungal, or viral infection that based on the investigator´s clinical assessment makes the subject unsuitable for the study, including recurrent/disseminated herpes zoster.
• Current or history of diverticulitis, complications of diverticulitis, history of diverticulosis requiring antibiotic treatment, current or history of chronic ulcerative lower gastrointestinal tract diseases or any other lower gastrointestinal condition that may predispose to perforation.
• Any history of malignancy or lymphoproliferative disease at any time, except curative treatment for nonmelanoma skin cancer or resected carcinoma in situ of the cervix.
• Have a transplanted organ/tissue or stem cell transplantation.
• Subject has an underlying metabolic, hematologic, renal, hepatic, pulmonary, neurologic, endocrine, cardiac, infectious, or gastrointestinal condition, which in the opinion of the investigator places the subject at unacceptable risk.
• Subject has a history of demyelinating diseases (including myelitis) or neurologic symptoms suggestive of demyelinating disease.
• Subject has received any live or attenuated vaccine ≤ 4 weeks prior to randomization or plans to receive it during the study including the safety follow up period.
• Subject has a history of clinically significant drug or alcohol abuse in the last 12 months as judged by the investigator.
• Pregnant or nursing (lactating) women.
