KYV-101 Sales Forecast Summary

Key Factors Driving KYV-101 Growth

Registrational and Regulatory Advancement in Key Autoimmune Indications

KYV-101 is progressing through registrational clinical programs with clear regulatory alignment with the US FDA:

• Stiff Person Syndrome (SPS): Kyverna completed enrollment in the registrational KYSA-8 Phase II trial, designed with FDA alignment to support a Biologics License Application (BLA) submission in the first half of 2026.
• Generalized Myasthenia Gravis (gMG): The KYSA-6 Phase II portion of a registrational Phase II/III study has reported positive interim data and is being expanded into a full registrational program, with Phase III enrollment expected to begin by the end of 2025.

Positive Clinical Data Showing Strong Potential Efficacy and Durability

Recent clinical and interim results show encouraging signals:

• In gMG, interim data from KYSA-6 showed 100% of patients demonstrated meaningful, rapid clinical improvements in key functional scores after a single KYV-101 infusion, even in patients resistant to previous immunosuppressive therapies.
• KYV-101 has shown durable disease control and improvements in multiple autoimmune settings in case reports and investigator-initiated trials, including improvements in mobility for SPS patients and sustained benefits in other treated individuals.

Significant Unmet Need and First-to-Market Opportunity in Rare Autoimmune Diseases

Stiff Person Syndrome (SPS) currently has no FDA-approved treatments, making KYV-101’s potential approval highly notable as a first-in-class therapy.

In myasthenia gravis, treatment options remain limited with many patients needing chronic immunosuppression despite suboptimal responses; a single-dose CAR T therapy could disrupt standard of care if validated.

Broad Potential Across Multiple Autoimmune and Neuroinflammatory Diseases

Beyond SPS and gMG, KYV-101 is being evaluated in additional autoimmune diseases:

• Ongoing Phase I/II trials in lupus nephritis (KYSA-1 and KYSA-3).
• Investigator-initiated and company trials exploring signals in multiple sclerosis, rheumatoid arthritis, and systemic sclerosis.
• Presentation of case data suggesting activity in multiple disease states enriches the strategic opportunity for KYV-101.

Strategic Corporate Positioning and Pre-Launch Preparedness

Kyverna has taken steps to support late-stage development and eventual commercialization:

• Alignment with the FDA on registrational pathways and trial designs for multiple indications.
• Investment in manufacturing capabilities with multiple partners to support commercial-scale production.
• Ongoing strategic outreach (e.g., virtual KOL events) to educate physicians on CAR T potential in autoimmune diseases.

KYV-101 Recent Developments

• In December 2025, Kyverna Therapeutics, a clinical-stage biopharmaceutical company focused on developing cell therapies for patients with autoimmune diseases, announced positive topline data from KYSA-8, its registrational Phase II trial of mivocabtagene autoleucel (‘miv-cel’, formerly KYV-101), a fully human, autologous CD19-targeting CAR T-cell therapy with CD28 co-stimulation, in stiff person syndrome (SPS).
• In October 2025, Kyverna Therapeutics, a clinical-stage biopharmaceutical company focused on developing cell therapies for patients with autoimmune diseases, announced the presentation of data from the Phase I portion of an investigator-initiated Phase I/II trial (IIT) evaluating KYV-101 in patients with active and treatment-refractory rheumatoid arthritis (RA).

KYV-101 Drug Summary

KYV-101 is an investigational autologous chimeric antigen receptor (CAR) T-cell therapy developed by Kyverna Therapeutics, utilizing a fully human anti-CD19 CAR construct previously validated in B-cell lymphoma patients for its improved safety profile with lower cytokine release. The therapy involves leukapheresis to collect patient T-cells, ex vivo genetic modification to express the CD19-targeting CAR, expansion, and reinfusion at a dose of 1×10^8 CAR+ T cells following lymphodepleting chemotherapy (e.g., fludarabine/cyclophosphamide), enabling deep and durable depletion of CD19+ B-cells—including autoreactive pathogenic B-cells in circulation and tissues—to reset aberrant immune responses in autoimmune diseases. It has demonstrated robust clinical efficacy in early trials, such as the KYSA-6 Phase II/III study in generalized myasthenia gravis (gMG), achieving rapid, sustained reductions in MG-ADL (-8.0 points) and QMG (-7.7 points) scores at 24 weeks across all patients regardless of prior biologics exposure, alongside positive effects on regulatory T-cells; additional programs target progressive multiple sclerosis (excellent Phase 1 safety with CNS penetration and immunomodulation) and systemic sclerosis. KYV-101 exhibits a manageable safety profile, with no high-grade cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) reported, and primarily low-grade adverse events. The report provides KYV-101’s sales, growth barriers and drivers, post usage and approvals in multiple indications.
