9. Male subjects/patients, if not surgically sterilized, must agree to use adequate contraception and not donate sperm from admission to the clinical site until 90 days after the last dosing of study drug.

10. Non-use of all over the counter medication, vitamin preparations and other food supplements, or herbal medications (eg, St. John's wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) before administration of study drug until completion of the follow-up assessment, unless, in the opinion of the Investigator and Sponsor, the medication will not interfere with the study drug.

11. Ability and willingness to abstain from alcohol, caffeine, and methylxanthine containing beverages or food (coffee, tea, cola, chocolate, or energy drinks) from 72 hours (3 days) prior to each admission to the clinical site.

12. Good physical and mental health on the basis of medical history (except for RA medical history in Part 2 of the study), physical examination, clinical laboratory, 12-lead ECG, and vital signs, as judged by the Investigator.

13. Resting supine blood pressure showing no clinically relevant deviations as judged by the Investigator. If initial results do not meet these criteria, blood pressure and/or pulse may be repeated if in the judgment of the Investigator there is a reason to believe the initial result is inaccurate (eg, white coat hypertension).

14. Computerized 12-lead ECG recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the Investigator. The ECG may be repeated if in the judgment of the Investigator there is a reason to believe the initial result is inaccurate.

15. All values for clinical laboratory tests of blood and urine within the normal range or showing no clinically relevant deviations as judged by the Investigator. Clinical laboratory tests may be repeated at the discretion of the Investigator.

16. Willing and able to sign the ICF.

Main inclusion criteria; Part 2 in RA patients only:

17. Treatment with MTX 10 to 25 mg QW as a DMARD for at least 12 weeks prior to screening, and with a stable dose for at least 4 weeks before screening, and that is expected to remain stable throughout the study period.

18. Having active RA, defined as:

• at least 6 swollen and 6 tender joints (based on 66/68 joint count), and

• CRP ≥ 8 mg/L, or ESR ≥ 28 mm/h

Exclusion Criteria:

1. Previous participation in the SAD study.

2. Employee of ICON or the Sponsor.

3. Use of any investigational drug or device within 30 days (or 5 half-lives if known, whichever is longer) prior to admission.

4. Any disease which, in the opinion of the Investigator, poses an unacceptable risk to the subjects or patients.

5. Females who are pregnant, lactating, or planning to attempt to become pregnant during this study or within 90 days after the last dosing of study drug.

8. Allergy or hypersensitivity to active ingredient or excipients.

9. Using tobacco or nicotine products within 60 days prior to study drug administration (for subjects in Part 1 only).

11. Positive drug and alcohol screen (opiates, methadone, cocaine, amphetamines [including ecstasy], phencyclidine, cannabinoids, barbiturates, benzodiazepines, tricyclic antidepressants, cotinine (only exclusionary in Part 1 of the study), and alcohol) at screening or admission to the clinical site.
