•3\. Body mass index (BMI) between 18\.5 and 30\.0 kg/m2 and body weight between 50 and 100 kg (both inclusive).
•4\. Screening parameters (vital signs, physical examination, clinical laboratory tests, 12\-lead ECG, chest x\-ray, thyroid function etc.) are within the normal range or if outside the normal range, assessed as clinically non\-significant by the Investigator (unless the value constitutes an explicit exclusion criterion).
•5\. Male volunteers must be willing to abstain from sexual intercourse, sperm donation or willing to use in all relationships with a partner from the opposite sex a condom for the male partner and another effective method of contraception (such as an intra\-uterine device, vaginal ring, oral contraceptive, injectable progesterone, or sub\-dermal implant) for the female partner from the time of dosing until 3 months after the last dosing date, unless one of the partners is medically confirmed to be either infertile or surgically sterile.
•6\. Female volunteers should be either post\-menopausal or surgically sterile
•Note: (Postmenopausal” is defined as 12 months of spontaneous amenorrhea or 6 months of spontaneous amenorrhea with serum follicle stimulating hormone levels \>40 mIU/ml, or 6 weeks post\-surgical bilateral oophorectomy with or without hysterectomy)
•7\. Capable, and amenable, to provide written informed consent to the study requirements.
•8\. Willing to abide by study restrictions for the entire study duration.

Exclusion Criteria

•1\. Positive test result for Quantiferon\-TB Gold test, syphilis, hepatitis B, hepatitis C, or HIV\-1 or 2\.
•2\. Any prior exposure to tocilizumab or to any other agent directly acting on interleukin\-6 or on its receptors including investigational products (e.g. siltuximab, sarilumab etc.).
•3\. Live virus vaccination within 3 months prior to screening or intention to receive live virus vaccination during the trial or up to 3 months after the administration of the study drug.
•4\. Administration of immunoglobulins for anti\-tetanus and antirabies post\-exposure prophylaxis within 3 weeks prior to administration of study drug.
•5\. History of immunodeficiency or other clinically significant immunological disorders, or auto\-immune disorders, ongoing or frequent/ recurring infection defined as more than 3 per year requiring treatment or prior herpes zoster not fully healed (including the post\-herpetic neuralgia period if occurring) within one year prior to randomization or history of systemic fungal infection at any time.
•6\. Allergy, or hypersensitivity to any recombinant human, or humanized antibodies, other therapeutic proteins, or any excipients in the study formulations.
•7\. Current manifestation of clinically significant (in the opinion of the Investigator) atopic allergy (e.g., asthma including childhood asthma currently showing clinical manifestations, urticaria, angioedema, eczematous dermatitis), hypersensitivity, or allergic reactions.
•8\. Non\-suitable skin for dosing or post\-dosing evaluations of upper arm (same arm to be used as the injection site in the both periods) for any reasons (including presence of tattoos, skin pigmentation disorders, scarring etc., which may obscure the injection site).
•9\. Blood donation, participation in any study requiring repeated blood sampling or haemorrhage requiring treatment or any transfusion in the past 3 months.
•10\. Screening blood pressure higher than 140 mm Hg (systolic) or higher than 90 mm Hg (diastolic) or volunteers currently on anti\-hypertensive drugs. Up to two repeats on different days are allowed and, in this case, the mean of the measurements will be used to decide on eligibility. Screening blood pressure is to be measured in the sitting position after 5 minutes rest.
