CalciMedica Reports Second Quarter 2023 Financial Results and Provides Clinical & Corporate Updates

International expansion of CARPO, a Phase 2b clinical trial of Auxora in acute pancreatitis (AP) patients with accompanying systemic inflammatory response syndrome (SIRS), in India

Expansion of team with key leadership appointments in regulatory and clinical development

Filing of an investigational new drug (IND) application for Auxora in acute kidney injury (AKI) expected by year-end 2023

LA JOLLA, CA, August 10, 2023 – CalciMedica Inc. (“CalciMedica”) (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 second quarter ended June 30, 2023.

“Following the completion of our reverse merger in March 2023, CalciMedica has taken critical steps to accelerate clinical activities with our lead compound, Auxora,” said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. “We undertook the international expansion of our Phase 2b CARPO study in acute pancreatitis with systemic inflammatory response syndrome and enrolled our first patient in India. Also, our collaborators at St. Jude Children’s Research Hospital are expanding our Phase 1/2 CRSPA study in asparaginase-induced pancreatic toxicity to additional sites. Further, we expect to file our IND application for Auxora in acute kidney injury by year-end.”

Dr. Leheny continued, “On the corporate side, we appointed a new Chief Regulatory Officer, Raven Jaeger, M.S., as well as a Senior Vice President of Clinical Development, Andrew Cunningham, M.D., MRCPI. Raven and Andrew have proved to be wonderful additions to our team and are providing leadership in the execution of our clinical and regulatory plans. Finally, due to the diligent work of our entire team, we were able to relist our common stock on the Nasdaq Capital Market in June, and we are pleased to be trading on that exchange.”

Clinical and Pre-Clinical Updates and Anticipated Milestones:

• In April 2023, CalciMedica initiated the international expansion of CARPO, a Phase 2b clinical trial of its lead candidate, Auxora, in AP patients with accompanying SIRS, in India and began enrolling patients there during the third quarter of 2023. CARPO enrollment is expected to be complete by the first quarter of 2024, with topline data available in the first half of 2024.

• In May 2023, the Independent Data Monitoring Committee for CARPO met to review data from the first 90 patients enrolled in the trial and determined that the trial should continue without modifications.

• Collaborators at St. Jude Children’s Research Hospital are expanding the Phase 1/2 CRSPA trial of Auxora in pediatric patients with asparaginase-induced pancreatic toxicity (AIPT) which has been a single-center study to date. Patient enrollment from additional sites is expected to begin in the fourth quarter of 2023.

• CalciMedica expects to file an IND application for Auxora in AKI by year-end 2023. If allowed, CalciMedica will then be in a position to initiate clinical trials in this indication in the first half of 2024, pending additional funding.

• In May 2023, preclinical data from studies in animal models of recurrent acute pancreatitis (RAP) and early chronic pancreatitis (CP) conducted at University of Szeged were published in The Journal of Clinical Investigation Insight. The data showed that inhibiting Orai1-mediated store-operated Ca2+ entry with a selective CRAC channel inhibitor prevented the progression of RAP and early CP into established CP, thus supporting the initiation of clinical studies assessing Orai1 inhibition in patients with RAP and early CP.

Financial Results for the Three and Six Months Ended June 30, 2023:

• Cash, Cash Equivalents and Marketable Securities: As of June 30, 2023, CalciMedica had $19.1 million in cash and cash equivalents, which the Company expects to be sufficient to fund operations for at least the next twelve months.

• Total Operating Expenses: Total operating expenses were $6.6 million for the three months ended June 30, 2023. Total operating expenses were $28.9 million for the six months ended June 30, 2023, which included $16.2 million of one-time charges related to accelerated vesting and severance for employees of Graybug Vision, Inc. at the time of the reverse merger with Graybug. The majority of costs stemming from the reverse merger have been expensed including the payment of accrued transaction expenses in the second quarter.

• Net Loss: Net loss was $6.3 million, or $1.11 per share (basic and diluted), and $25.6 million, or $7.86 per share (basic and diluted), for the three and six months ended June 30, 2023, respectively.

Corporate Updates

• In May 2023, CalciMedica announced the appointments of Raven Jaeger, M.S. as Chief Regulatory Officer and Andrew Cunningham, M.D., MRCPI as Senior Vice President of Clinical Development.

• In June 2023, CalciMedica’s common stock was relisted on the Nasdaq Capital Market. CalciMedica trades on the Nasdaq Capital Market under the ticker symbol “CALC”.

About Auxora^™

CalciMedica’s lead clinical compound, Auxora^™, is a potent and selective small molecule inhibitor of Orai1-containing CRAC channels that is being developed for use in patients with acute inflammatory and immunologic illnesses. CRAC channels are found on many cell types, including pancreatic acinar cells, lung endothelium cells and immune system cells, where aberrant activation of these channels may play a key role in the pathobiology of acute and chronic inflammatory syndromes. Auxora is currently being evaluated in: (i) a Phase 2b trial for AP with accompanying SIRS, called CARPO, (ii) an investigator-sponsored Phase 1/2 trial called CRSPA being conducted in pediatric patients with AIPT as a side effect of pediatric acute lymphoblastic leukemia treatment with asparaginase, and (iii) a Phase 2 dose-ranging pharmacodynamic study in critical COVID-19 patients. There are currently no approved therapies to treat either AP or AIPT. In previous trials, patients responded well to Auxora regardless of severity or cause of disease. CalciMedica is also exploring the potential of Auxora treatment for other acute indications including acute kidney injury and acute respiratory distress syndrome.

About CARPO

CARPO is an international, randomized, double-blind, placebo-controlled, dose-ranging trial intended to establish efficacy in AP with accompanying SIRS. It is expected to enroll 216 patients. AP can be a life-threatening condition where the pancreas becomes inflamed, sometimes leading to pancreatic cell death or necrosis, systemic inflammation, organ failure and death. There are an estimated 275,000 hospitalizations for AP annually in the United States, of which approximately 40% present with SIRS, which can compromise the function of other tissues or organs, especially the lungs. Organ failure is responsible for much of the mortality seen in AP. There is currently no approved therapy for AP. Details of the CARPO trial are available on clinicaltrials.gov (NCT04681066).

About CRSPA

CRSPA is an investigator-sponsored Phase 1/2 trial being conducted in pediatric acute lymphoblastic leukemia (ALL) patients with AIPT, which is acute pancreatitis toxicity caused by the administration of asparaginase and for which there is no approved therapy. Treatment with asparaginase triggers the development of AIPT in 7-10% of these patients, with approximately half developing pancreatic necrosis and/or pseudocysts. CalciMedica believes that the CRSPA trial has defined an optimal pediatric dose for Auxora in this setting and the trial is currently being expanded to additional sites. Details of the CRSPA trial are available on clinicaltrials.gov (NCT04195347).

About CalciMedica

CalciMedica is a clinical-stage biopharmaceutical company focused on developing novel CRAC channel inhibition therapies for inflammatory and immunologic diseases. CalciMedica’s proprietary technology targets the inhibition of CRAC channels designed to modulate the immune response and protect against tissue cell injury, with the potential to provide therapeutic benefits in life-threatening inflammatory and immunologic diseases for which there are currently no approved therapies. CalciMedica’s lead product candidate Auxora^™, a proprietary, intravenous-formulated CRAC channel inhibitor, has demonstrated positive and consistent clinical results in multiple completed efficacy clinical trials. Auxora is in development for AP with SIRS and AIPT. CalciMedica was founded by scientists from Torrey Pines Therapeutics and the Harvard CBR Institute for Biomedical Research, and is headquartered in La Jolla, CA.
