"We have continued to spotlight the growing body of evidence supporting the development of Auxora for the treatment of AKI with respiratory failure, including publications in two peer-reviewed journals, multiple presentations at medical meetings, and a symposium at the 43rd Vicenza Course AKI-CRRT-EBPT and Critical Care Nephrology meeting. We look forward to the readout of our Phase 2 KOURAGE trial expected in early 2026," said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica.

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, the Company's randomized, double-blind, placebo-controlled Phase 2 trial of Auxora™ in patients with Stage 2 or Stage 3 AKI with associated respiratory failure. CalciMedica plans to enroll 150 patients in KOURAGE, with data expected in early 2026.
• Publication in the American Journal of Nephrology (AJN): In June 2025, CalciMedica announced a publication in AJN, titled, "Inhibition of Calcium Release-Activated Calcium (CRAC) Channels to Treat Acute Kidney Injury: Design and Rationale of the KOURAGE Study." The manuscript describes the preclinical and clinical evidence supporting Auxora as a potential treatment for AKI with respiratory failure, as well as the rationale for the patient selection and endpoint selection for the Company's Phase 2 KOURAGE trial.
• "Auxora for the Treatment of AKI" Symposium: In June 2025, the Company presented a symposium titled "Auxora for the Treatment of AKI" at the 43rd Vicenza Course AKI-CRRT-EBPT and Critical Care Nephrology meeting. The symposium featured oral presentations delivered by Sudarshan Hebbar, M.D., CMO of CalciMedica; Javier Neyra, M.D., Associate Professor of Medicine and Associate Director of the Nephrology Research & Training Center at University of Alabama at Birmingham; and Lakhmir Chawla, M.D., Clinical Professor of Medicine at University of California San Diego, CMO at ExThera Medical, and Chair of the KOURAGE Steering Committee. Webcasts of the presentations are available on the "Medical Events and Presentations" section of CalciMedica's IR website.
• Publication in the Thrombosis Update: In July 2025, a manuscript authored by CalciMedica and collaborators, titled, "Reduction in D-dimer Levels After Treatment with Auxora in Patients with Severe Covid-19 Pneumonia," was published in the Thrombosis Update. The manuscript highlights a biomarker analysis from patients treated with Auxora in the Company's previously completed Phase 2 CARDEA trial in severe COVID-19 pneumonia. In the analysis, Auxora was found to significantly decrease D-dimer levels and other biomarkers of systemic inflammation, with these decreases correlating with positive outcomes in patients. These findings showing Auxora's anti-inflammatory effects and endothelial stabilization support its continued development for the treatment of acute illnesses with a strong inflammatory component, such as AKI and AP.
• Oral presentation and panel discussion at the American Society of Nephrology (ASN) 3rd Acute Kidney Injury: From Bench to Bedside Conference: In May 2025, Dr. Hebbar delivered an oral presentation titled "Experiences with AKI Clinical Trial Design" and participated in a panel discussion at the ASN 3rd Acute Kidney Injury: From Bench to Bedside Conference.

Acute Pancreatitis (AP) Program Update

• Conducted initial meeting with the U.S. Food and Drug Administration (FDA) on next steps in AP program: The Company conducted a productive initial meeting with the FDA to present the findings from the Phase 2b CARPO trial and discuss the design of a pivotal trial in AP. Additional meetings with the FDA are anticipated in the second half of 2025, with alignment on trial design anticipated around the end of the year. This will be the first pivotal trial in the U.S. for a therapeutic in AP.
• Poster presentation at Digestive Disease Week (DDW) 2025: In May 2025, Kenneth A. Stauderman, Ph.D., co-Founder and CSO of CalciMedica, presented a poster titled "Patients with Acute Pancreatitis (AP) and Accompanying Systemic Inflammatory Response Syndrome (SIRS) Have a Larger Volume of Distribution Compared to Healthy Volunteers" at DDW 2025.

Financial Results for the Second Quarter Ended June 30, 2025:

Cash Position: Cash, cash equivalents, and short-term investments were $18.0 million as of June 30, 2025. The Company expects its cash position to be sufficient to fund its current operating plan into the middle of 2026.

R&D Expenses: Research and development expenses were $4.1 million for the three months ended June 30, 2025, compared to $4.2 million for the three months ended June 30, 2024. The decrease of $0.1 million was primarily due to a decrease in CMC costs offset by an increase in clinical activities relating to Auxora.

G&A Expenses: General and administrative expenses were $2.6 million for the three months ended June 30, 2025, compared to $2.4 million for the three months ended June 30, 2024. The increase of $0.2 million was primarily due to an increase in personnel costs partially offset by a decrease in professional services.

Other Income: Other income was $0.7 million for the three months ended June 30, 2025, compared to $2.6 million for the three months ended June 30, 2024. The decrease of $1.9 million was primarily due to a decrease in fair value adjustments to the Company's financial instruments.

Net Loss: Net loss was $6.0 million, or $0.40 per basic and diluted share, for the three months ended June 30, 2025, compared to $4.0 million, or $0.36 per basic and diluted share, for the three months ended June 30, 2024.
