• Subjects who meet any of the following criteria:

  • Surgically sterilized (confirmed 6 month prior to enrollment)
  • Have surgically sterilized sexual partner (confirmed 6 month prior to enrollment)
  • Postmenopausal, defined as at least 1 year of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous levels of follicle-stimulating hormone (FSH) above 40 U/L and estradiol below 30 ng/L is confirmatory)

Exclusion criteria:

• Previous exposure to adalimumab or proposed adalimumab biosimilar drugs.
• Any finding in the medical examination (including blood pressure (BP), pulse rate (PR) or electrocardiogram (ECG)) that deviates from normal and judged as clinically relevant by the investigator.
• Any evidence of a concomitant disease judged as clinically relevant by the investigator including gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological, hormonal disorders or diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders.
• History of relevant orthostatic hypotension, fainting spells, or blackouts.
• Chronic or relevant acute infections.
• Positive result for HIV, hepatitis B virus (HBV), and hepatitis C (Hep C) at screening.

• Inability to comply with dietary regimen of trial site.
• Any out-of-range laboratory values considered clinically significant by the investigator; (subjects with creatine kinase (CK) values 2 times the upper limit of normal (ULN) at Day -1 are to be excluded from participation).
• Subject is assessed as unsuitable for inclusion by the investigator, for instance, because he is considered not able to understand and comply with trial requirements, or has a condition that would not allow safe participation in the trial.
• Subjects with any immunological disorders or auto-immune disorders, (e.g., Rheumatoid arthritis (RA), lupus erythematosus, scleroderma, etc.).

All randomized subjects

From single dose administration till 10 weeks; up to 70 days

All events with an onset after the single dose of trial medication up to a period of 10 weeks (70 days) were assigned to the treatment phase for evaluation and were considered to be TEAEs. The SAF population was used which consisted of all subjects that received a single dose of trial medication.
