Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* To assess the safety of anti-CD19 CAR T cell therapy in subjects with active, ACPA positive and treatment refractory RA (Phase-I)
* To assess the safety of anti-CD19 CAR T cell therapy and of rituximab in subjects with active, ACPA positive and treatment refractory RA (Phase-II)
* To assess ACPA seroconversion after anti-CD19 CAR T cell or rituximab therapy in subjects with active, ACPA positive and treatment refractory RA (Phase-II)
Participants in the test-arm will receive a single dose of KYV-101 i.v., an autologous fully-human anti-CD19 CAR T-cell immunotherapy. In the comparator group patients will receive 2x1 g Rituximab i.v.
Follow-up time (both arms) is 52 weeks with regular visits at the site.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigational product (IMP), KYV-101, is an autologous fully-human anti-CD19 CAR T-cell immunotherapy. . Before IMP infusion, patients will receive a premedication of 4 mg Dimetindenmaleat iv or equivalent antihistamine and 1000 mg oral acetaminophene. Prophylactic doses of acyclovir of 400mg 2x daily as well as cotrimoxazole 960mg 3x weekly will be administered orally following CAR T cell infusion until week 24. Tocilizumab 8mg/kg will be administered intravenously when required for treatment of IMP-related cytokine release syndrome. Dexamethasone as needed will be administered intravenously when required for treatment of neurological adverse event (ICANS).
In the control arm in phase II, rituximab will be administered. Rituximab, a chimeric monoclonal antibody targeting CD20, induces B cell depletion and is authorized for treatment of RA. A dose of 1000 mg will be administered intravenously at baseline and at day 14 as per summary of product characteristics. The need for further courses will be evaluated 24 weeks after baseline where retreatment of 1000 mg rituximab may be initiated if residual disease activity remains.
Follow-up time (both arms) is 52 weeks with regular visits at the site.

Rituximab
In the Comparator group patients will receive 2x1 g Rituximab i.v. (Day 0 and Day 14).
Retreatment of 1000 mg rituximab i.v. may be initiated at week 24 if residual disease activity remains, otherwise retreatment should be delayed until disease activity returns. A DAS-28-CRP \> 3.2 will be used as a non-binding guidance for the re-treatment decision.

Exclusion Criteria
* Severely impaired renal (eGFR ≤ 30 ml/min/m2), liver (Child Pugh B or C), or heart andor pulmonary (NYHA III or IV, blood oxygenation \<92%) function
* Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to partici-pate in the study or confounds the ability to interpret data from the study

* Any concomitant severe active infection, e.g. HIV, hepatitis B or C, SARS-CoV-2 (COVID-19), or active tuberculosis as defined by a posi-tive Quantiferon TB-test. If presence of latent tuberculosis is estab-lished then treatment according to local guidelines must have been ini-tiated prior to enrollment
