Comparison of PK and Tolerability of MSB11022 Administered by AI or PFS

The primary objective of this study is to demonstrate equivalence of the pharmacokinetic (PK) profile of MSB11022 administered by either an auto-injector (AI) or a pre-filled syringe (PFS) as single subcutaneous (s.c.) injection of 40 mg.


Eligibility Criteria:
Inclusion Criteria:

1. Willing and able to sign the informed consent form (ICF).
2. Healthy male subjects and female subjects of non-childbearing and childbearing potential.
3. Aged 18 to 55 years, inclusive, at screening.
4. Have all screening results (vital signs, physical examination, clinical laboratory tests, 12-lead ECG) within the normal range or outside the normal range but assessed as not clinically significant by the Investigator.
5. Body weight between 50.0 and 100.0 kg, inclusive, and a body mass index between 18.5 and 30.0 kg/m2, inclusive.
6. Male subjects must be either surgically sterile or willing to use contraceptive methods until 5 months after the dose of investigational medicinal product (IMP).
7. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test at screening and before randomization. WOCBP must agree to use highly effective methods of contraception to prevent pregnancy for at least 4 weeks before randomization until 5 months after the dose of IMP. For all postmenopausal female subjects, serum follicle-stimulating hormone (FSH) is tested at screening to identify their postmenopausal status.
8. Willing and able to comply with scheduled visits, treatment plan, laboratory tests and all other study procedures.

Exclusion Criteria:

1. Female subjects must not be pregnant or lactating at screening through at least 5 months after the last treatment with IMP.
2. A history and/or current presence of clinically significant atopic allergy (eg, asthma including childhood asthma), hypersensitivity or allergic reactions (either spontaneous or following drug administration), including known or suspected clinically relevant drug hypersensitivity to any components of the study drug formulations, comparable drugs, or to latex. Mild hay fever is allowed if outside of acute exacerbation requiring treatment. Assessment of clinical significance of reported atopic or allergic condition in medical history of participant is at Investigator decision.
3. Have either active or latent tuberculosis (TB) as indicated by a positive QuantiFERON®-TB Gold test or have a history of TB. Subjects who have an indeterminate QuantiFERON-TB Gold test result may be re-tested once during screening. If the re-test result is negative, the subject is eligible to participate in the study. If the re-test result is indeterminate again or positive, the subject is NOT eligible to participate in the study.
4. Lifetime history of invasive systemic fungal infections (eg, histoplasmosis) or other opportunistic infections, including recurrent or chronic local fungal infections.
5. Have had a serious infection (associated with hospitalization and/or which required intravenous anti-infectives or intravenous antibiotics) within 6 months prior to study drug administration and/or a significant infection (excluding resolved infections like a mild common cold) within 2 weeks prior to the screening or during the screening period unless the infection has resolved completely within 2 weeks before admission.
6. Have had herpes zoster

   1. within the last year, or
   2. more than 2 herpes zoster infections in their lifetime prior to randomization.
7. History or presence (at time of screening or randomization) of frequent (ie, requiring treatment more than 3 times a year), chronic or recurrent infections.
8. Have previously been exposed to adalimumab or approved or proposed adalimumab biosimilar drugs if known. Have been exposed to any anti-tumor necrosis factor alfa class drug whether approved drug or investigational drug\\proposed biosimilar.
9. Intake of an investigational drug in another study within 3 months or 5 half-lives, whichever is longer, before the intake of the IMP in this study or planned intake of an investigational drug during the course of this study.
10. Use of depot injectable solutions (except for depot contraception drugs) within 6 months before randomization.
11. Smoking more than equivalent of (as determined by investigator) 10 cigarettes per day and/or inability to refrain from smoking or consuming nicotine containing products during the residential stay at the trial site.
12. History of alcohol abuse within one year from screening and/or inability to refrain from intake of alcoholic beverages from 48 hours prior to Day -1 until Day 14 postdose or a positive screen for alcohol on admission to the clinical site prior to study drug administration.
13. Positive screen for drugs of abuse at screening or at admission to the clinical site prior to study drug administration.
14. Donated more than 450 mL of blood within 60 days or 450 mL of blood products (eg, plasma, platelets) within 2 weeks prior to admission to the clinical site or intend to donate during the study.
15. Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), dietary supplements or herbal medication during the 2 weeks prior to study drug administration or longer if the medication has a long half-life. For female subjects, oral contraceptives and hormone replacement therapy are allowed.
16. History of cancer including lymphoma, leukemia, and skin cancer.
17. Impaired liver function as determined at screening or admission to the clinic by one of the following:

    * Serum alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) \>1.5 times the upper limit of normal (ULN) at screening or admission to the clinic.
    * A positive hepatitis C virus (HCV) antibody test or hepatitis B surface antigen (HBsAg) test and/or core antibody test for immunoglobulin G (IgG) and/or immunoglobulin M (IgM) at screening.
18. History of or current signs or symptoms of demyelinating disease including optic neuritis and/or multiple sclerosis.
19. History of immunodeficiency (including a positive test for human immunodeficiency virus \[HIV\] 1 or 2 antibodies) or other clinically significant immunological disorders, or autoimmune disorders, (eg, rheumatoid arthritis, lupus erythematosus, scleroderma).
20. History of and/or current gastrointestinal, renal, cardiovascular, hematological (including pancytopenia, aplastic anemia or blood dyscrasia), metabolic (including known diabetes mellitus), central nervous system or pulmonary disease considered as significant by the Investigator.
21. Received a live vaccine within 12 weeks prior to screening visit or plan for any such vaccination during the study or within 4 months after study drug administration.
22. Any abnormal skin conditions or potentially obscuring tattoos, pigmentation, or lesions in the areas intended for s.c. injection, that in opinion of Investigator do not allow assessment of local tolerability.
23. Legal incapacity or limited legal capacity.
24. Significant concurrent disease or a known medical condition which would make the participant unfit to participate in the study as per Investigator assessment.
