Enrollment ongoing in Phase 2 KOURAGE trial of Auxora™ in acute kidney injury (AKI) with respiratory failure; data expected in 1H 2026

Positive discussions with FDA on pivotal trial in acute pancreatitis (AP); final trial design expected in 1H 2026

Cash position expected to fund operations into 2H 2026

LA JOLLA, Calif., Nov. 12, 2025 /PRNewswire/ -- CalciMedica Inc. ("CalciMedica" or the "Company") (NASDAQ:CALC), a clinical-stage biopharmaceutical company focused on developing novel calcium release-activated calcium (CRAC) channel inhibition therapies for acute and chronic inflammatory and immunologic illnesses, today reported financial results for the third quarter ended September 30, 2025 and provided clinical and corporate updates.

"Enrollment continues in our Phase 2 KOURAGE trial evaluating Auxora in patients with AKI with respiratory failure, and we look forward to sharing data in the first half of 2026. As we approach this milestone, we are encouraged by AKI animal model data recently shared at ASN and results in PAH animal models published in JCI Insight, both of which provide further mechanistic rationale for CRAC channel inhibition as a promising approach for treating AKI," said Rachel Leheny, Ph.D., CEO of CalciMedica. "Additionally, discussions with the FDA have been positive regarding our program in AP. We expect our recently announced collaboration with Telperian and its AI-driven analytics platform will enable us to leverage insights from completed Auxora trials to optimize the design of our pivotal trial in AP, which we expect to finalize in the first half of 2026."

Recent Clinical & Corporate Highlights:

Clinical Updates & Anticipated Milestones

Acute Kidney Injury (AKI) with Respiratory Failure Program Update

- Enrollment ongoing in Phase 2 KOURAGE trial: Enrollment is ongoing in KOURAGE, CalciMedica's randomized, double-blind, placebo-controlled Phase 2 trial of Auxora™ in patients with Stage 2 or Stage 3 AKI with respiratory failure. The Company plans to enroll 150 patients in KOURAGE, with data expected in the first half of 2026.
- Poster presentation at the American Society of Nephrology (ASN) Kidney Week 2025: In November 2025, CalciMedica and collaborators from Indiana University School of Medicine, including David P. Basile, Ph.D., Professor of Anatomy, Cell Biology and Physiology, presented a poster titled "Store-Operated Calcium-Channel Inhibitor Auxora Improves Kidney Function Following Ischemia-Induced AKI in Rats" at ASN Kidney Week 2025. In the study, treatment with Auxora versus placebo significantly reduced Th17 cells in both the kidney and lung, significantly increased glomerular filtration rate (GFR), and decreased renal injury in a rat model of AKI. The findings, particularly the new observations of IL-17 reductions in the lung, provide strong mechanistic support for Auxora as a potential treatment for severe AKI with respiratory failure. The inclusion and exclusion criteria of CalciMedica's Phase 2 KOURAGE study are expected to enrich for patients with elevated IL-17 levels, which have been shown to correlate with mortality and major adverse kidney events in severe AKI.

Acute Pancreatitis (AP) Program Update

- Positive discussions with the U.S. Food and Drug Administration (FDA) on pivotal trial in AP: CalciMedica has had constructive engagement with the FDA regarding the design of a pivotal trial in AP. The Company expects to finalize the pivotal trial design in the first half of 2026. This study is anticipated to be the first pivotal trial in the U.S. for a therapeutic in AP.
- Announced collaboration with Telperian to leverage AI insights to support the design of pivotal trial design in AP: In October 2025, CalciMedica and Telperian announced a collaboration to integrate Telperian's advanced AI platform into analyses of data from completed Auxora clinical trials. Insights from this work are expected to help inform the finalization of the design of CalciMedica's pivotal trial in AP and support ongoing regulatory discussions with the FDA.

Preclinical Program Updates

- Publication in JCI Insight: In November 2025, a manuscript authored by CalciMedica and collaborators titled "Combination of Orai1 Inhibitor CM5480 with Specific Therapy Mitigates Pulmonary Hypertension and Its Cardiac Dysfunction" was published in JCI Insight. The publication describes preclinical data supporting CalciMedica's proprietary CRAC channel inhibitor candidate, CM5480, as a potential first-in-class, differentiated therapy for the treatment of pulmonary arterial hypertension (PAH). In an animal model of PAH, CM5480 restored or improved multiple disease-affected pathways and functions—including heart contraction and cardiac output, gene expression profiles, DNA repair, and metabolism. Treatment with CM5480 also significantly reduced right ventricular dysfunction (RVD) both as a monotherapy and in combination with existing PAH therapies. Beyond PAH, these findings suggest that CRAC channel inhibition may directly improve RVD, which occurs in approximately half of patients with sepsis, the leading cause of AKI. This potential effect provides additional mechanistic support for Auxora as a potential treatment for AKI with respiratory failure.

Financial Results for the Third Quarter Ended September 30, 2025:

Cash Position: Cash, cash equivalents, and short-term investments were $14.1 million as of September 30, 2025. The Company expects its cash position to be sufficient to fund its current operating plan into the second half of 2026.

R&D Expenses: Research and development expenses were $3.9 million for the three months ended September 30, 2025, compared to $3.6 million for the three months ended September 30, 2024. The increase of $0.3 million was primarily due to an increase in clinical trial and preclinical activities offset by a decrease in consultants and other costs.

G&A Expenses: General and administrative expenses were $1.8 million for the three months ended September 30, 2025, compared to $2.2 million for the three months ended September 30, 2024. The decrease of $0.4 million was primarily due to a decrease in professional services and consultants and other costs.

Other Income (Expense): Other expenses were $2.2 million for the three months ended September 30, 2025, compared to other income of $0.1 million for the three months ended September 30, 2024. The increase of $2.3 million in expenses was primarily due to a non-cash increase in fair value adjustments to the Company's financial instruments.

Net Loss: Net loss was $7.8 million, or $0.52 per basic and diluted share, for the three months ended September 30, 2025, compared to $5.6 million, or $0.50 per basic and diluted share, for the three months ended September 30, 2024.
