Press Release

FDA feedback on the Auxora™ pivotal program in acute pancreatitis and potential future development in acute kidney injury expected in 2Q 2026

Preclinical and IND-enabling studies advancing for CM5480, an oral CRAC channel inhibitor candidate, with IND submission in pulmonary hypertension expected in 2027

LA JOLLA, Calif., May 12, 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 serious acute and chronic inflammatory, immunologic, and cardiopulmonary diseases, today reported financial results for the first quarter ended March 31, 2026 and provided clinical and corporate updates.

"We continue to work closely with the FDA as we finalize the design of our pivotal program for Auxora in AP and explore potential future development in AKI, both serious illnesses with high unmet need that are not adequately addressed by current standard of care," said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. "As we progress in these discussions and continue to advance our oral CRAC channel inhibitor, CM5480, in preclinical and IND-enabling studies for pulmonary hypertension, we are encouraged by preclinical data recently published in Human Immunology, which offers a strong endorsement of the mechanistic rationale for selective CRAC channel inhibition in inflammatory and immune-mediated diseases."

Recent Program Highlights:

Acute Pancreatitis (AP) Program Update

• Continued positive FDA engagement on pivotal program in AP: CalciMedica continues to engage constructively with the U.S. Food and Drug Administration (FDA) regarding the design of a potential pivotal program evaluating Auxora in AP, with FDA feedback on program design expected in the second quarter of 2026. This would represent the first U.S. pivotal program evaluating a therapeutic candidate for AP, a serious inflammatory disease with approximately 300K hospitalizations annually in the U.S. alone.
• 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 was well-tolerated and 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.
• Preclinical data published in Human Immunology: In April 2026, a manuscript authored by CalciMedica collaborators titled "Single-cell Transcriptomics Reveals Targeted Modulation of Inflammatory Repertoire by SOCE Blockers" was published in Human Immunology. The publication describes preclinical data showing that in normal human peripheral blood mononuclear cells (PBMCs) in a T-cell activation model, store-operated calcium entry (SOCE) blockers such as Auxora inhibit the expression of pro-inflammatory and cytotoxic genes within regulatory T cells, while crucially preserving tolerance-associated anti-inflammatory pathways. This selective modulation provides further mechanistic support for the continued evaluation of Auxora in acute and chronic inflammatory and immunologic illnesses such as AP and acute kidney injury. The data also suggest potential implications for targeted immune modulation in transplantation settings.

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

• FDA feedback expected regarding potential future development in AKI: Following comprehensive internal and external safety reviews after the Company paused enrollment in the Phase 2 KOURAGE trial of Auxora in patients with Stage 2 or Stage 3 AKI with associated AHRF, no evidence of drug-related toxicity was identified. The Company expects feedback from the FDA regarding potential future development of Auxora in AKI in the second quarter of 2026.

Pulmonary Hypertension (PH) Program Update

• Preclinical activities to advance CM5480 in PH underway: Studies are ongoing to further characterize the pharmacology, pharmacokinetics, and safety profile of CM5480, CalciMedica's proprietary oral CRAC channel inhibitor candidate with the potential to be a first-in-class, differentiated therapy targeting pulmonary vascular and right ventricular remodeling, key drivers of disease progression in PH, including pulmonary arterial hypertension. An IND submission for CM5480 is anticipated in 2027.

Financial Results for the First Quarter Ended March 31, 2026:

Cash Position: Cash and cash equivalents were $8.2 million as of March 31, 2026. 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 $3.5 million for the three months ended March 31, 2026, compared to $4.2 million for the three months ended March 31, 2025. The decrease of $0.7 million was primarily due to a decrease in preclinical and clinical trial related activities, and a decrease in chemistry, manufacturing and controls activities.

G&A Expenses: General and administrative expenses were $2.1 million for the three months ended March 31, 2026, compared to $2.3 million for the three months ended March 31, 2025. The decrease of $0.2 million was primarily due to a decrease in personnel costs.

Other Income: Other income was $10.6 million for the three months ended March 31, 2026, compared to $1.5 million for the three months ended March 31, 2025. The increase of $9.1 million was primarily due to the fair value adjustments to our promissory note and common stock warrants. 

Net Income/Loss: Net income was $5.0 million, or $0.31 per basic share and $0.30 per diluted share, for the three months ended March 31, 2026, compared to a net loss of $5.0 million, or $0.36 per basic and diluted share, for the three months ended March 31, 2025.

CalciMedica's proprietary technology targets the inhibition of CRAC channels to modulate the immune response and protect against tissue cell injury, with the potential to provide therapeutic benefits in serious and life-threatening conditions with high unmet need. CalciMedica's lead product candidate Auxora™ has demonstrated positive clinical results in multiple completed efficacy clinical trials. The Company has reported data from a Phase 2b trial (CARPO; NCT04681066) evaluating Auxora in patients with acute pancreatitis (AP) and accompanying systemic inflammatory response syndrome (SIRS), as well as from a Phase 2 trial (CARDEA; NCT04345614) in patients with severe COVID-19 pneumonia. The Company initiated a Phase 2 trial (KOURAGE; NCT06374797) evaluating Auxora in patients with acute kidney injury (AKI) with associated acute hypoxemic respiratory failure (AHRF); in January 2026, CalciMedica paused enrollment in the trial following a recommendation from the Independent Data Monitoring Committee and, as a next step, plans to discuss potential future development in AKI with the FDA. In addition, CalciMedica is advancing CM5480 as a potential oral therapy for pulmonary hypertension (PH), supported by preclinical data demonstrating effects on pulmonary vascular and right ventricular remodeling.
