Auto-injector Real Life Handling in Patients

To assess the real-life patient handling experience with the use of an autoinjector in patients with moderate to severe active Rheumatoid Arthritis (RA) who self-inject AVT02 subcutaneously (SC).

This is an autoinjector handling study to assess the ability of patients to self-inject AVT02 with the proposed autoinjector in the normal standard of care setting, and to assess the reliability of the proposed autoinjector for AVT02.

On Week 0 (Day 0) eligible patients will be trained by qualified study site personnel (Investigator-led trained injection) following the first injection. The patient will return to the clinic on Week 2 (Day 14) and will be asked to selfinject the second dose (trained self-injection). The injection will be observed by the study personnel and the patient provided any assistance necessary to complete an acceptable injection.

On Week 4 (Day 28), Week 6 (Day 42), and Week 8 (Day 56), the patient will return to clinic and will be asked to self-inject the dose without assistance but under observation of qualified trial staff (observed self-injection).

Observations of autoinjector handling events are recorded independently by both trial site staff and patients using standardized questionnaires.

Any failures to inject will be investigated to determine if they are mechanical failures of the device or due to use error of the patient.

All failures will be further investigated to determine the root cause, and where necessary, appropriate mitigation will be developed and implemented.

In the Extension period (Weeks 9 to 56), AVT02 40 mg will be administered every other week via prefilled syringe (PFS) starting from Week 10 and ending at week 54. The final efficacy evaluation is expected at Week 56.

The clinical study report (CSR) will include the data from the 8week active period. The extension phase CSR will include the data from the 48-week extension period (Weeks 9 to 56).

* No evidence of active TB on chest radiograph within 3 months prior to the first dose of study drug.
* Documented history of adequate prophylaxis initiation prior to receiving study drug in accordance with local recommendations.
* No known exposure to active TB after most recent prophylaxis.
* Asymptomatic at Screening and baseline (BL).
* Patients who test positive for TB must be treated for 1 month prior to taking part in the study. Investigators should check with the medical monitor before enrolling patients receiving active treatment for TB.
* Investigators should check with the medical monitor before enrolling such patients.
* Sexually active women of childbearing potential must agree to use highly effective contraception (hormonal contraception pills or injection or implants, sterilization, and abstinence) for the duration of the study and until 3 months after the last dose of the study drug.
* Male patients must agree to use contraception for the duration of the study and agree not to donate sperm during and for 3 months after the last dose of study drug.
* Evidence of a personally signed and dated informed consent document indicating that the patient (or a legal representative) has been informed of all pertinent aspects of the study.
* Patients who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria:

* Patients with previous experience of self-administering medications using an autoinjector or pen (either marketed or investigational).
* Patients who upon initial training are determined not to be acceptable candidates for self-administration.
* RA with significant secondary involvement of any systemic organ (including but not limited to vasculitis, pulmonary fibrosis).
