Kyverna Therapeutics Reports Pipeline Progress and Second Quarter 2026 Financial Results
FDA grants RMAT designation for miv-cel in non-active secondary progressive multiple sclerosis (naSPMS) based on compelling clinical data, further expanding the therapy’s potential across neuroimmunology
On track to complete rolling BLA submission for miv-cel in stiff person syndrome (SPS) in Q4 2026; KYSA-8 12-month topline data expected in Q3 2026
Enrollment in KYSA-6 Phase 3 trial in generalized myasthenia gravis (gMG) expected to be completed in mid-2027; longer-term follow-up Phase 2 topline data expected in Q3 2026
Reiterates operating runway into 2028
EMERYVILLE, Calif., August 11, 2026 -- Kyverna Therapeutics, Inc. (Nasdaq: KYTX), a late-stage clinical immunology company pioneering transformative therapies for people with neurologic autoimmune diseases, today reported financial results for the second quarter ended June 30, 2026, and provided a business update.
“Kyverna continues to advance our rolling BLA submission for stiff person syndrome, progress commercial launch readiness activities and accelerate enrollment in our registrational trial in generalized myasthenia gravis, while advancing our pipeline,” said Warner Biddle, Chief Executive Officer of Kyverna Therapeutics. “With three RMAT indications and the potential to deliver the first approved CAR T-cell therapy for autoimmune diseases, we are well positioned to achieve our goal of freeing patients from life-long disease burden and chronic immunotherapies with a single dose of miv-cel.”
Progress in Miv-cel Neuroimmunology Franchise
•SPS Rolling Biologic License Application (BLA) Submission Underway and Commercial Readiness Activities On-Track:
oKyverna has initiated its rolling BLA, submitted the Chemistry, Manufacturing and Controls (CMC) module and is on track to complete its submission in the fourth quarter of 2026.
oThe Company plans to seek priority review, under the Regenerative Medicine Advanced therapy (RMAT) designation, positioning miv-cel for potential commercial launch in 2027.
oKyverna continues to advance activities to enable a successful rare disease launch in SPS upon approval. These efforts include hiring key commercial leadership roles, commercial site activation, a commercial supply agreement, payer and patient advocacy engagement, and healthcare professional education.
oThe Company plans to report 12-month topline data from KYSA-8 in Q3 2026.
•Enrollment Ongoing in KYSA-6 Registrational Trial for gMG:
oKyverna continues to advance its Phase 3 gMG trial and expects to complete enrollment by mid-2027. The Company anticipates sharing longer-term follow-up Phase 2 topline data in Q3 2026.
•Advancing Progressive Multiple Sclerosis (PMS) Strategy with RMAT Designation Granted for Miv-cel for Treatment of Non-active Secondary Progressive Multiple Sclerosis:
oRMAT designation has been granted for miv-cel in naSPMS by the FDA based on compelling clinical data from investigator-initiated trials (IIT) at Stanford University and the University of California, San Francisco in patients with PMS. This designation provides the opportunity for increased FDA engagement and eligibility for priority and rolling reviews, as well as accelerated approval pathways, with the goal of bringing transformative innovations to patients more quickly.
oKyverna expects to provide an update on its PMS development strategy by early 2027, as well as additional data from the Stanford Phase 1 IIT in Q4 2026.
“In progressive multiple sclerosis, miv-cel’s potential to stabilize or improve disability status with a single dose could represent a transformative treatment advance given the steady progression patients face despite available therapies. We look forward to sharing our development strategy in progressive multiple sclerosis, leveraging discussions with the FDA through our RMAT designation, by early 2027,” said Naji Gehchan, Chief Medical and Development Officer of Kyverna.
•Additional Miv-cel Neuroimmunology Franchise Opportunities
oKyverna continues to explore miv-cel with alternative or no preconditioning regimens and the potential for outpatient administration supported by miv-cel's consistent and well-tolerated safety profile.
Leadership Appointments
oIn the second quarter, Kyverna strengthened its leadership team with the appointments of Greg Martini as Chief Financial Officer, Nadia Dac as Chief Commercial Officer, and Ritesh Srivastava as Chief Legal and Compliance Officer.
Financial Results for the Second Quarter Ended June 30, 2026
•Kyverna reported $199.4 million in cash, cash equivalents, and marketable securities as of June 30, 2026, which in addition to amounts available for draw from the Oxford Finance amended loan facility, is expected to provide operating runway into 2028.
•Research and Development (R&D) expenses were $24.8 million for the second quarter ended June 30, 2026.
•General and Administrative (G&A) expenses were $14.8 million for the second quarter ended June 30, 2026.
•For the quarter ended June 30, 2026, the Company reported a net loss of $38.3 million, or a net loss per common share of $0.63.
About Miv-cel (mivocabtagene autoleucel, KYV-101)
Miv-cel is a fully human, autologous, CD19-targeting CAR T-cell therapy with CD28 co-stimulation, uniquely designed for potency and tolerability, which is under investigation for B-cell-driven autoimmune diseases. With a single administration, miv-cel has potential to achieve deep B-cell depletion and immune system reset to deliver durable, drug-free, disease-free remission in autoimmune diseases.
About Kyverna Therapeutics
