Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study consists of two intervention periods. Subjects will be randomised 1:1:1 to one of the three possible treatment pairs (DRL_TC & RP, DRL_TC & RMP or RMP & RP) and immediately thereafter to one of the two possible sequences for the pair (e.g. for the DRL_TC & RMP pair to receive DRL_TC on Day 1 (Period I) and RMP on Day 1 (Period II) or RMP on Day 1 (Period I) and DRL_TC on Day 1 (Period II). All the 3 (DRL_TC/RP/RMP) contain Tocilizumab.
Consequently, each subject will receive two of the following three treatment regimens: DRL_TC (162 mg/0.9 mL); RP (162 mg/0.9 mL); RMP (162 mg/0.9 mL) during the study.

DRL_TC /RP/RMP: will be given as single subcutaneos injection in the upper arm on day 1 during Period 1 and day 1 during period 2.
Participants will be randomized to either of the 3 IP's (DRL_TC/Actemra/RoActemra) on day 1 and then further randomized to one of the 2 sequences after this (eg if DRL_TC (out of the 3 options available) given during Period 1 then during period 2 on day 1-either participant will be dosed with RP or RMP.
Period I consist of 42 days and Period II consist of 42 days. But during washout period there is flexibility up to 9 weeks (63 days)
Site will be responsible for adherence to the intervention. 2-3 attempts will be made to contact the participants via phone if not booked for dosing during period 2.

Safety laboratory investigations:

12-lead ECG will be recorded at screening, on the day of check-in, with in 1 hour prior to dosing as well as 15 minutes after dosing with a window period of +/- 5 minutes
on Day 1 ,Day 5 of both periods and EOS (Day 43 of Period II). A 12-lead ECG is to be recorded at 72h after dosing in both the periods also.

Fasting (approximately 10 hours) blood samples will be collected for performing laboratory investigations, following laboratory parameters will be evaluated at respective evaluations:

Screening and EOS (after 10 h fasting) : Safety Laboratory Panel 1 assessment i.e. Total blood count including hemoglobin, hematocrit, mean corpuscular volume, leukocyte counts (total and differential), and platelet count; clinical chemistry including urea, creatinine, uric acid, glucose, ALT, AST, total bilirubin (and direct if increased), sodium, potassium, chloride, calcium, total proteins, albumin, and LDH; coagulation tests (aPTT and INR); thyroid hormones (T3, T4 and TSH); lipid profile (including total, LDL and HDL cholesterol as well as triglycerides) and urine evaluation with dipstick (confirmation with microscopic examination, if abnormalities are found)

On EOS, Quantiferon- TB Gold test will be performed for all subjects.

On the day of check-in Day-1 and on Days 2 , 5 , 15 (after 10 h fasting) for both the period : -Safety Laboratory Panel 2 assessment i.e. Total blood count; clinical chemistry including urea, creatinine, uric acid, glucose, ALT, AST, total bilirubin (and direct if increased), sodium, potassium, chloride, calcium and LDH; coagulation tests (aPTT and INR); lipid profile (as in Screening) and urine evaluation with dipstick (confirmation with microscopic examination if abnormalities are found).

On Days 9 , Day 29 for both the period : Safety Laboratory Panel 3 assessment i.e. Total blood count; clinical chemistry including urea, creatinine, uric acid, glucose,ALT, AST, total bilirubin (and direct if increased), sodium, potassium, chloride, calcium and LDH; coagulation tests (aPTT and INR); lipid profile (as in Screening) and urine evaluation with dipstick (confirmation with microscopic examination if abnormalities are found).

AEs will be monitored throughout the study duration. For all those subjects who will be followed up for anti-drug antibodies at 3 monthly intervals (starting from Day
90 post the second dose) until 2 consecutive negative results or one year post-dose, whichever is earlier), all ongoing AEs need to be monitored.
Adverse events can be reported or elicited during open-ended questioning, examination, or evaluation of a subject.

Clinically significant abnormal laboratory findings or other abnormal assessments that are detected during the study or are present at Screening and significantly worsen following the study drug administration will be reported as AEs or SAEs.



The Investigator establish a diagnosis of the event based on signs, symptoms, and/or other clinical information.



The Investigator makes an assessment of intensity for each AE and SAE reported during the study. The assessment of intensity will be based on the CTCAE v-5.0 or the latest applicable version.



The Investigator assess the relationship between the study medication and the occurrence of each AE/SAE, and categorize the relationship to the study drug either as;

Related: There is a reasonable causal relationship between the study drug administered and the AE;

Not Related: There is no reasonable causal relationship between the study drug administered and the AE
