Special focus should be given to lung conditions to ensure it is sufficiently close to normal to avoid excessive risks upon study participation.
11 Patients with any history or current presence of known demyelinating disease.
12 Patients with any history of or presence of an active neoplasia except for successfully treated (at least five years in advance) non-metastatic cutaneous squamous cell or basal cell carcinoma and⁄or localised carcinoma in situ of the cervix.
13 Patients with renal impairment (Cockcroft-Gault creatinine clearance less than 60 mL/ min) or liver function impairment (bilirubin greater than 1.25 x Upper Limit Normal (ULN) (2.5xULN with indirect bilirubin contributing to greater than 80% of the total bilirubin as per the laboratory test for patients with documented Gilbert syndrome), international normalized ratio (INR) greater than 1.25, alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than 1.5 x ULN) at screening, unless the values are not clinically significant as per the investigator.
14 Patients with history of chronic alcoholism or drug abuse or other addictions (for the purposes of the study in the opinion of the Investigator; testing not necessary).
15 Patients with diseases that have immune suppression in their clinical course and/ or need for treatment with immune suppressive treatments such as patients with an organ graft requiring maintenance immune suppression.
16 Clinically significant chronic obstructive pulmonary disease (COPD) in the opinion of the Investigator.

Patients with history of active TB within 3 years of the start of study treatment can only be included if documentation of a completed treatment is provided.
Note: For indeterminate results, two repeats are allowed. Patients may be re-screened and randomised after completing at least 3 months of prophylactic treatment with relevant appropriate medications as a standard approach, and treatment confirmed as effective in patient documentation before randomization. In emergent situations, when the patient needs quick therapy for RA, 4 weeks of prophylactic treatment can be considered appropriate.
18 Patients with active TB, unrecovered hepatitis B, herpes zoster including the period of post-herpetic neuralgia within 1 year of randomisation, or any other ongoing clinically relevant active infection, even if localised.
19 Patients with positive screening for hepatitis B surface antigen (HBsAg), hepatitis C or human immunodeficiency virus (HIV).

Brief Summary   This study is being conducted to evaluate efficacy equivalence between Dr. Reddy’s Abatacept and reference product. In addition, safety, immunogenicity will also be compared. This is in line with the guidelines issued by various regulatory agencies for development of biosimilars.
The rationale for the main phase of study is to compare the efficacy, safety, and immunogenicity of DRL_AB in establishing biosimilarity; the transition phase is to rule out any difference between DRL_AB with RMP in safety or immunogenicity in RA patients who are already on treatment with the RMP when they switch to DRL_AB; and long term safety extension phase for evaluation of the safety following long term administration.
