ArmTypeDescription
KYV101EXPERIMENTALParticipants in this arm will receive a single dose of KYV-101 i.v., an autologous fully-human anti-CD19 CAR T-cell immunotherapy.
RituximabACTIVE_COMPARATORIn 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.

Frequently asked questions about KYV101

What is KYV-101 used for?

KYV-101 is an autologous fully-human anti-CD19 CAR T-cell immunotherapy being studied for autoimmune diseases, including primary progressive multiple sclerosis, rheumatoid arthritis, systemic sclerosis, and idiopathic inflammatory myopathies. It is currently in clinical development and is not approved by the FDA.

What does KYV-101 target?

KYV-101 targets CD19, a protein found on B cells. As a CAR T-cell therapy, it is designed to recognize and eliminate CD19-expressing cells, which are implicated in autoimmune diseases. This mechanism is being evaluated in clinical trials for conditions like multiple sclerosis and systemic sclerosis.

Who makes KYV-101?

KYV-101 is developed by Kyverna Therapeutics, Inc., a biopharmaceutical company. The company's stock ticker is KYTX. Kyverna is conducting clinical trials to evaluate the safety and efficacy of KYV-101 in patients with various autoimmune diseases.

What phase is KYV-101 in?

KYV-101 is in Phase 1 and Phase 2 clinical trials. It has received FDA Fast Track and RMAT (Regenerative Medicine Advanced Therapy) designations. The drug is investigational and has not been approved by the FDA for any indication.

What clinical trials is KYV-101 in?

KYV-101 is being studied in several trials, including NCT06152172 (CARTIMMUNE) for autoimmune diseases, NCT06384976 (KYSA-7) for progressive multiple sclerosis, and NCT06475495 for rheumatoid arthritis. A trial for systemic sclerosis, NCT06400303, was terminated. These trials are active but not recruiting.

Is KYV-101 the same as KYV101?

Yes, KYV-101 is also known as KYV101. It is an autologous fully-human anti-CD19 CAR T-cell immunotherapy. These names refer to the same investigational drug being developed by Kyverna Therapeutics for autoimmune conditions.
