Extending Company's leadership position in autoimmune CAR T with prioritized indication strategy; pivoting to late-stage development and commercialization

First-to-market opportunity with KYV-101 in stiff person syndrome; 40% enrolled in pivotal Phase 2 trial with first BLA filing targeted for 2026; fast-follow indications in myasthenia gravis and lupus nephritis

Efficiently expanding into broader autoimmune indications and increasing patient reach with KYV-102 using whole blood rapid manufacturing

Cash runway into 2027 to deliver key milestones

EMERYVILLE, Calif., Jan. 13, 2025 /PRNewswire/ -- Kyverna Therapeutics, Inc. (Kyverna, NASDAQ: KYTX), a clinical-stage biopharmaceutical company focused on developing cell therapies for patients with autoimmune diseases, announced it will present its 2025 strategic priorities and key milestones during a presentation that will be made by Chief Executive Officer, Warner Biddle, at the 43^rd Annual J.P. Morgan Healthcare Conference today, Monday, January 13, 2025.

"2025 will be a transformational year for Kyverna as we accelerate our next wave of growth and pivot to late-stage development and commercialization with our differentiated CD19 CAR T construct, KYV-101," said Warner Biddle, Chief Executive Officer, Kyverna. "Building upon our leadership position, we have sharpened our focus and execution on a prioritized set of opportunities – stiff person syndrome, myasthenia gravis and lupus nephritis – each with a clear and rapid path to market, where we can deliver a profound patient impact. Importantly, these indications serve as a beachhead to other neuroinflammatory and rheumatologic diseases, which we will continue to pursue in a capital-efficient manner alongside next-generation innovations, starting with KYV-102, designed to broaden access to CAR T."

Mr. Biddle added, "We are pleased with our clinical progress to date, having 40% of patients enrolled in KYSA-8, our pivotal KYV-101 Phase 2 trial in stiff person syndrome, which enables us to target a BLA filing in 2026 and puts us on track to deliver the first approved CAR T therapy in an autoimmune disease. Our fast-follow indication, myasthenia gravis, has already enrolled patients in a company-sponsored trial, KYSA-6, and we expect to report interim Phase 2 data in the second half of 2025."

Strategic priorities for the upcoming year include:

• Focused execution on company-sponsored KYSA studies evaluating KYV-101 in priority indications that offer a clear and rapid path to market. This includes advancing ongoing clinical studies in stiff person syndrome (KYSA-8), myasthenia gravis (KYSA-6), and lupus nephritis (KYSA-1 and KYSA-3).
• Continue regulatory interactions leveraging the U.S. Food and Drug Administration's Regenerative Medicine Advanced Therapy and Orphan Drug designations for stiff person syndrome and myasthenia gravis.
• Evaluate additional opportunities in a capital-efficient manner, harnessing investigator-initiated trials (IITs) and other KYSA studies – including multiple sclerosis, systemic sclerosis, and others – to inform the next priority indications for the Company to advance into late-stage development.
• Advance next-generation innovations, including KYV-102, incorporating the Company's whole-blood rapid manufacturing approach, which aims to improve the CAR T patient experience, eliminate apheresis and ultimately broaden CAR T access.

Anticipated Milestones:

Based on these strategic priorities, Kyverna has issued the following guidance on upcoming program milestones:

• Stiff Person Syndrome:
  • Complete pivotal Phase 2 enrollment mid-2025
  • Report topline pivotal Phase 2 data 1H 2026
  • BLA filing in 2026
• Myasthenia Gravis:
  • Confirm registrational path with regulators 1H 2025
  • Report interim Phase 2 data 2H 2025
• Lupus Nephritis:
  • Report Phase 1 data 2H 2025
• Future pipeline:
  • File KYV-102 investigational new drug application 2H 2025

The Company has a cash runway into 2027 to deliver on these key inflection points, with $321.6 million of cash, cash equivalents, and marketable securities as of September 30, 2024.

About KYV-101
Uniquely designed, KYV-101 is an autologous, fully human CD19 CAR T-cell product candidate with highly potent CD28 co-stimulation and designed for tolerability, which is under investigation for B-cell-driven autoimmune diseases.  With KYV-101, Kyverna is pioneering a durable disease-clearing approach aiming for deep B cell depletion, an immune system reset, and long-term remission in autoimmune diseases.

It is currently being evaluated in company sponsored, open-label, Phase 2 trials in stiff person syndrome and myasthenia gravis and Phase 1/2 trials for lupus nephritis, as well as in investigator-initiated trials and company-sponsored trials for multiple indications. The clinical experience to date with KYV-101 highlights the potential for transformative clinical outcomes in autoimmune patients.  

About KYV-102
KYV-102 leverages the same fully human, clinically validated CD19 CAR-T construct as KYV-101.  It incorporates the Ingenui-T platform, a proprietary, next-generation process that utilizes whole blood with a rapid manufacturing approach. 

Kyverna intends to broaden CAR T patient access with KYV-102 by eliminating the need for apheresis starting material and reducing the manufacturing turnaround time from conventionally manufactured CAR T products.  

About Kyverna Therapeutics
Kyverna Therapeutics, Inc. (Nasdaq: KYTX) is a clinical-stage biopharmaceutical company focused on liberating patients through the curative potential of cell therapy. Kyverna's lead CAR T-cell therapy candidate, KYV-101, is advancing through clinical development with Phase 2 trials for stiff person syndrome and myasthenia gravis, and two ongoing multi-center Phase 1/2 trials for patients with lupus nephritis.  The Company is also harnessing investigator-initiated trials and other KYSA studies, including in multiple sclerosis and systemic sclerosis, to inform the next priority indications for the Company to advance into late-stage development.  Its pipeline includes next-generation CAR T-cell therapies in both autologous and allogeneic formats with properties intended to be well suited for use in B cell-driven autoimmune diseases.  For more information, please visit https://kyvernatx.com.
