Strong Financial Position; Ended the Quarter With $321.6 Million in Cash, Cash Equivalents and Marketable Securities

EMERYVILLE, Calif., Nov. 13, 2024 /PRNewswire/ -- Kyverna Therapeutics, Inc. (Nasdaq: KYTX), a clinical-stage biopharmaceutical company focused on developing cell therapies for patients with autoimmune diseases, today reported its business highlights and financial results for the third quarter ended September 30, 2024.

"With KYV-101 advancing towards later stages of development, we are scaling Kyverna to bring the transformative impact of our differentiated CAR T therapies to patients with a range of B cell-driven autoimmune diseases. Since I joined the company in September, we have made significant progress, both clinically and operationally, to maintain Kyverna's leadership position," said Warner Biddle, Chief Executive Officer of Kyverna. "At ECTRIMS, we shared promising clinical data highlighting KYV-101's potential to reset the immune system and durably improve symptoms of neuroinflammatory diseases. At ACR Convergence 2024 later this week, we will share the latest clinical data from lupus nephritis patients demonstrating the potential for durable treatment effect at the target clinical dose."

Mr. Biddle continued, "In order to deliver on the long-term opportunity for KYV-101, we are working to sharpen our focus, leveraging our clinical datasets and academic partnerships, and continue executing our KYSA clinical trial programs. In 2025 we will share our long-term plan in both neuroinflammatory and rheumatologic diseases."

Third Quarter 2024 and Recent Business Highlights

KYV-101 Clinical Data Updates:

KYV-101 Clinical Data in Neuroinflammatory Indications Presented at ECTRIMS: In September 2024, in a company-sponsored symposium at the 40th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), Kyverna presented data from 11 patients with stiff-person syndrome, myasthenia gravis and multiple sclerosis reinforcing KYV-101's broad potential in B cell-driven neuroinflammatory diseases. Numerous patients demonstrated ongoing durability at one year and beyond.
KYV-101 Clinical Data in Lupus Nephritis to be Presented at the American College of Rheumatology (ACR) Convergence 2024: At a company-sponsored symposium at ACR Convergence 2024, being held in Washington, DC from November 14 - 19, 2024, Kyverna will share clinical data from lupus nephritis patients with at least six months of follow-up after treatment with KYV-101 at its selected target dose. The Company expects to share efficacy, safety and durability data, and highlight KYV-101's impact on clinically relevant pillars of disease: preservation of kidney function, symptom improvement in underlying disease and elimination of immunosuppressive therapy.

Also at ACR Convergence 2024, Kyverna will present one oral and two poster presentations outlining its approach to understanding mechanisms of immune reset and detailing Kyverna's next-generation CAR T-cell therapies, including preclinical data on Ingenui-T, the Company's 3-day manufacturing process using autologous whole blood as starting material.

KYV-101 Clinical Development Program Updates:

As of November 2024, Kyverna initiated Phase 2 dosing with KYV-101, received RMAT designation in two indications and received Orphan Drug Designation in three indications.

Stiff-Person Syndrome: Kyverna anticipates initiating dosing by end-of-year in KYSA-8, the Company's Phase 2 study in Stiff-Person Syndrome, for which KYV-101 has been granted an RMAT designation and Orphan Drug Designation by the U.S. Food and Drug Administration (FDA).
Myasthenia Gravis: Kyverna initiated dosing in KYSA-6, the Company's Phase 2 study in myasthenia gravis, for which KYV-101 has been granted an RMAT designation and Orphan Drug Designation by the U.S. FDA. Additionally, in November 2024, the European Medicines Association (EMA) granted Orphan Drug Designation to KYV-101 for treatment of myasthenia gravis.
Multiple Sclerosis: Kyverna's academic partners at Stanford and UCSF initiated dosing in Phase 1 investigator-initiated trials (IITs) for the use of KYV-101 in multiple sclerosis. Kyverna intends to leverage these clinical insights and collaborate with FDA to design a potential registration-enabling study for KYSA-7 in multiple sclerosis.
Lupus Nephritis: Kyverna completed the dose-escalation cohort of KYSA-1 and is currently treating patients at the target dose in both KYSA-1 (US) and KYSA-3 (EU), the Company's Phase 1/2 studies in lupus nephritis.
Systemic Sclerosis: Kyverna initiated dosing in KYSA-5, the Company's Phase 1/2 study in systemic sclerosis. In September 2024, KYV-101 was granted Orphan Drug Designation from the U.S. FDA for the treatment of systemic sclerosis.

Corporate, Operational & Manufacturing Updates

Kyverna Leadership Updates: Kyverna strengthened its management team and Board of Directors with key leadership appointments to support the company's evolution in preparation for its next phase of growth, including:
- Warner Biddle as Chief Executive Officer (CEO) and a member of the Board of Directors, bringing over 30 years of global experience in commercial, product planning and franchise leadership, including successful launches of several CAR-T products.
- Christi Shaw and Mert Aktar to the Board of Directors, bringing decades of industry leadership in corporate strategy and manufacturing expertise, including for gene and cell therapy.
- Cara Bauer as Chief Human Resources Officer (CHRO), bringing expertise in human resources strategy, culture building and talent development to support scaling global organizations.

In addition, Kyverna announced today that James Chung, M.D., Ph.D., the Company's Chief Medical Officer, will step down from his position to pursue external opportunities, effective November 22, 2024. Kyverna has initiated a search for an external candidate to replace Dr. Chung.

Expanded Manufacturing Capacity to Support Advancing Clinical Development: In October 2024, Kyverna signed an agreement with ElevateBio as a second-source supplier for KYV-101.
Publication Highlights Manufacturing Capabilities with KYV-101 in Autoimmune Disease: In October 2024, Kyverna and collaborators published "Successful Generation of Fully Human, Second Generation, Anti-CD19 CAR T Cells for Clinical Use in Patients with Diverse Autoimmune Disorders" in Cytotherapy. The publication details Kyverna's 100% manufacturing success rate for KYV-101 in 20 patients, demonstrating a robust and consistent process for manufacturing and delivering its fully human anti-CD19 CAR T cell therapy across various autoimmune indications.
