Safety concern warrants reevaluation of study design, including enrollment criteria
Potential future trial with Auxora™ in AKI to be evaluated after data analysis
LA JOLLA, Calif., Jan. 28, 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 announced the discontinuation of its Phase 2 KOURAGE clinical trial evaluating Auxora™ in patients with Stage 2 or Stage 3 acute kidney injury (AKI) with associated acute hypoxemic respiratory failure (AHRF), a population characterized by high mortality and a lack of approved therapies. The decision follows a recommendation from the trial’s Independent Data Monitoring Committee (IDMC).
During a prescheduled interim data review, the IDMC identified a safety concern that, in its view, warrants reevaluation of the study design, particularly with respect to patient enrollment criteria. There were no deaths in the trial that were assessed by investigators or CalciMedica as being related to study drug (either Auxora or placebo). In addition, no serious adverse events met the criteria for expedited reporting to the U.S. Food and Drug Administration (FDA). Based on the IDMC’s recommendation, the Company has discontinued the trial and plans to perform a comprehensive review of the unblinded clinical data.
The Company will assess the impact of baseline characteristics, disease severity, concomitant therapies, and other factors on patient outcomes. These analyses are expected to inform how future clinical evaluation of Auxora in AKI may proceed.
“Based on the IDMC’s feedback, we will review the unblinded KOURAGE data and explore modifications to the trial design, particularly patient enrollment criteria, that may support further clinical testing of Auxora in patients with AKI,” said Rachel Leheny, Ph.D., CEO of CalciMedica. “To date, no treatment-related safety concern has been observed across more than 350 critically ill patients treated with Auxora in completed clinical trials, including the Phase 2b CARPO trial in acute pancreatitis (AP) and the Phase 2 CARDEA trial in severe COVID-19 pneumonia. We remain optimistic about Auxora’s potential in acute inflammatory illnesses and look forward to finalizing the design of a pivotal trial in AP, pending FDA feedback, in the first half of 2026, while also advancing a second CRAC channel inhibitor, CM5480, as a potential first-in-class, differentiated therapy for pulmonary arterial hypertension.”
The Company has notified the FDA about the trial discontinuation and will work with investigators to ensure all patients currently enrolled in the trial complete the full 90-day follow-up.
