Internal and external reviews of all available safety data from the Phase 2 KOURAGE trial in acute kidney injury (AKI) did not identify evidence of a drug-related toxicity with Auxora™

Design of pivotal program in acute pancreatitis (AP) expected in 1H 2026

JCI Insight publication of preclinical data demonstrates CM5480 as a potential differentiated therapy in pulmonary arterial hypertension (PAH); IND submission anticipated in 2027

LA JOLLA, Calif., March 3, 2026 /PRNewswire/ -- CalciMedica Inc. ("CalciMedica" or the "Company") (NASDAQ:CALC), a clinical-stage biopharmaceutical company developing novel calcium release-activated calcium (CRAC) channel inhibition therapies for acute and chronic inflammatory and immunologic illnesses, today reported financial results for the year ended December 31, 2025 and provided clinical and corporate updates.

"First and foremost, in acute kidney injury, we and our external advisors have reviewed the unblinded KOURAGE data and have found no evidence of a drug-related toxicity. We look forward to discussions with the FDA about potential future clinical studies in AKI. We are also advancing Auxora towards the pivotal program in acute pancreatitis following constructive FDA engagement and the peer-reviewed publication of our Phase 2b CARPO results. The Company plans to finalize the design for this program in the first half of this year," said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. "Concurrently, we continue to advance our second CRAC channel inhibitor, CM5480, in pulmonary arterial hypertension, following the recent publication of preclinical data which demonstrate its potential in cardiopulmonary disease."

Recent Program Highlights:

Acute Kidney Injury (AKI) with Acute Hypoxemic Respiratory Failure (AHRF) Program Update

Phase 2 KOURAGE trial safety review: In January 2026, CalciMedica announced the discontinuation of the Phase 2 KOURAGE trial evaluating Auxora in patients with Stage 2 or Stage 3 AKI with associated AHRF. The decision followed a recommendation from the trial's Independent Data Monitoring Committee (IDMC) regarding a safety concern relating to a mortality imbalance that warranted reevaluation of the study design. The IDMC did not identify evidence of drug-related toxicity, and the Company's comprehensive review, performed in conjunction with external experts, reached the same conclusion. Imbalances in the patients' severity of disease at baseline may have contributed to the observed safety concern.
Next steps in AKI: The Company plans to discuss the KOURAGE data and potential future development in AKI with the FDA in the second quarter of 2026. The trial remains ongoing for patient follow-up.

Acute Pancreatitis (AP) Program Update

Positive FDA engagement on pivotal program in AP: CalciMedica continues constructive discussions with the U.S. Food and Drug Administration (FDA) regarding the pivotal program for Auxora in AP and expects to finalize the program design in the first half of 2026. This would represent the first U.S. pivotal program evaluating a therapeutic candidate for AP, an illness with approximately 300K hospitalizations annually in the U.S.
Phase 2b CARPO trial results published in eClinicalMedicine: In February 2026, a manuscript authored by CalciMedica and collaborators titled "Zegocractin for acute pancreatitis with systemic inflammatory response syndrome: a randomized, controlled, dose-ranging, phase 2b trial" was published in eClinicalMedicine, a journal in The Lancet Discovery Science suite. The publication details previously announced topline results from 214 patients enrolled in the Phase 2b CARPO trial of Auxora in AP with systemic inflammatory response syndrome (SIRS). In hyper-inflamed patients, Auxora demonstrated clinically meaningful, dose-dependent reductions in median time to solid food tolerance. Across the overall study population, Auxora demonstrated dose-dependent improvements in multiple clinically relevant endpoints, including reductions in organ failure, necrotizing pancreatitis, and time to medically indicated discharge. Notably, medium- and high-dose Auxora arms achieved a statistically significant 100% reduction in new-onset severe respiratory failure compared to placebo (p < 0.05), and the high-dose Auxora arm achieved a statistically significant stratified win ratio of 1.640 (p < 0.05), which represents a hierarchical composite of mortality, new-onset severe respiratory failure, new-onset necrotizing pancreatitis, and time to medically indicated discharge. Auxora was generally well tolerated, with a trend of decreasing treatment-emergent serious adverse event (TESAE) rates with increasing doses of drug. Additionally, there were no drug-related TESAEs or deaths in patients receiving the high dose of Auxora.

Pulmonary Arterial Hypertension (PAH) Program Update

Publication in JCI Insight highlighting CM5480 in a pulmonary arterial hypertension (PAH) model: 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 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.
Preclinical activities to advance CM5480 in PAH underway: Ongoing studies are being conducted to further characterize CM5480's pharmacology, pharmacokinetics, and safety profile to support IND (investigational new drug)-enabling development in PAH. An IND submission is currently anticipated in 2027.

Financial Results for the Year Ended December 31, 2025:

Cash Position: Cash, cash equivalents, and short-term investments were $13.0 million as of December 31, 2025. The Company expects its cash position to be sufficient to fund its current operating plan into the fourth quarter of 2026.

R&D Expenses: Research and development expenses were $15.2 million for the year ended December 31, 2025, compared to $14.5 million for the year ended December 31, 2024. The increase of $0.7 million was primarily due to an increase in preclinical and clinical trial related activities offset by a decrease in chemistry, manufacturing, and control activities and personnel costs.

G&A Expenses: General and administrative expenses were $7.9 million for the year ended December 31, 2025, compared to $9.7 million for the year ended December 31, 2024. The decrease of $1.8 million was primarily due to a decrease in consultants and other costs and professional services offset by an increase in personnel costs driven by stock-based compensation.

Other Income (Expense): Other expenses were $6.4 million for the year ended December 31, 2025, compared to other income of $10.5 million for the year ended December 31, 2024. The increase of $16.9 million of expense was primarily due to the non-cash fair value adjustments to the Company's financial instruments, an increase in interest expense associated with the Company's promissory note, and a decrease in interest income offset by miscellaneous income.

Net Loss: Net loss was $29.6 million, or $1.97 per basic and diluted share, for the year ended December 31, 2025, compared to $13.7 million, or $1.22 per basic and diluted share, for the year ended December 31, 2024.
