CalciMedica Reports Third Quarter 2026 Financial Results and Provides Clinical & Corporate Updates

Auxora Phase 1b proof-of-concept data in pulmonary hypertension (PH) and CM5480 IND submission both anticipated in mid-2027

Cash, cash equivalents and short-term investments of $13.8 million as of September 30, 2026; cash expected to fund current operating plan into the second half of 2027

LA JOLLA, Calif., Nov. 10, 2026 (GLOBE NEWSWIRE) — 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 inflammatory, immunologic, and cardiopulmonary diseases, today reported financial results for the third quarter ended September 30, 2026, and provided clinical and corporate updates.

“We continue to advance our pulmonary hypertension strategy, with data from the Auxora Phase 1b proof-of-concept trial in PH and the CM5480 IND submission both anticipated in mid-2027,” said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. “Preclinical models suggest CRAC channel inhibitors may provide a differentiated approach in pulmonary hypertension by targeting multiple disease drivers, including right ventricular dysfunction, which is the principal cause of mortality and not directly targeted by existing therapies. In acute pancreatitis, FDA alignment on a trial with a patient enrichment strategy and endpoints provides a clear framework for the next stage of development in a disease with no approved therapies. We expect multiple meaningful catalysts over the next 12 months.”

Recent Program Highlights:

Pulmonary Hypertension (PH) Program Update

• Auxora Phase 1b proof-of-concept trial in PH planned: CalciMedica plans to evaluate Auxora in a Phase 1b trial in patients with pulmonary hypertension to generate initial clinical evidence regarding the effects of CRAC channel inhibition on cardiac and pulmonary function. Details on this trial and the target patient population are expected by year-end with data anticipated in mid-2027.
• CM5480 preclinical and IND-enabling studies advancing: Studies are ongoing to further characterize the pharmacology, pharmacokinetics, and safety profile of CM5480, CalciMedica’s oral CRAC channel inhibitor candidate for chronic use in PH. Preclinical data continue to suggest CM5480 may be differentiated by directly protecting right ventricular function, a key driver of outcomes in PH that is not directly targeted by existing therapies. An IND submission is anticipated in mid-2027.

Acute Pancreatitis (AP) Program Update

• FDA alignment on next steps in the registration path for Auxora in AP: In July, following a Type C Focused Meeting, CalciMedica announced that FDA aligned with the Company’s Phase 2b trial design for Auxora in AP. The Phase 2b trial will test if enrollment based on elevated lactate dehydrogenase (LDH) levels successfully selects for more severe patient outcomes assessed using severe respiratory failure as the primary endpoint. AP is a serious inflammatory disease with no FDA-approved therapies and approximately 300,000 hospitalizations annually in the U.S.¹

Corporate Update

• One-for-five reverse stock split: In August, CalciMedica announced a 1-for-5 reverse stock split, with split-adjusted trading on the Nasdaq Capital Market beginning August 31, 2026, under the symbol “CALC.” The split reduced issued and outstanding shares from approximately 34.5 million to approximately 6.9 million and has brought CalciMedica into compliance with the minimum bid price requirement for continued listing.

Financial Results for the Third Quarter Ended September 30, 2026:

Cash Position: Cash, cash equivalents and short-term investments were $13.8 million as of September 30, 2026. The Company expects its cash, cash equivalents and short-term investments to fund its current operating plan into the second half of 2027.

R&D Expenses: Research and development expenses were $2.3 million for the three months ended September 30, 2026, compared to $3.9 million for the three months ended September 30, 2025. For the nine months ended September 30, 2026, research and development expenses were $7.9 million, compared to $12.1 million for the nine months ended September 30, 2025. The decrease of $4.2 million was primarily due to a decrease in nonclinical and clinical trial related activities, consultants and chemistry, manufacturing and controls activities offset by an increase in personnel costs.

G&A Expenses: General and administrative expenses were $2.4 million for the three months ended September 30, 2026, compared to $1.8 million for the three months ended September 30, 2025. For the nine months ended September 30, 2026, general and administrative expenses were $6.5 million, compared to $6.6 million for the nine months ended September 30, 2025. The decrease of $0.1 million was primarily due to a decrease in personnel and facilities costs offset by an increase in professional services, consultants and other costs.

Other Income/Expense: Total other income was $3.1 million for the three months ended September 30, 2026, compared to total other expense of $2.2 million for the three months ended September 30, 2025. For the nine months ended September 30, 2026, total other income was $10.0 million, compared to total other expense of $0.1 million for the nine months ended September 30, 2025. The increase of $10.1 million primarily reflected an increase in income from changes in the fair value of the Company’s financial instruments.

Net Income/Loss: Net loss was $1.7 million inclusive of a noncash $3.1 million gain in other income/expense, or $0.24 per basic and diluted share, for the three months ended September 30, 2026, compared to a net loss of $7.8 million, or $2.59 per basic and diluted share, for the three months ended September 30, 2025. For the nine months ended September 30, 2026, net loss was $4.4 million, or $0.96 per basic and diluted share, compared to a net loss of $18.8 million, or $6.61 per basic and diluted share, for the nine months ended September 30, 2025.

About Pulmonary Hypertension
Pulmonary hypertension (PH) encompasses a diverse group of diseases, including pulmonary arterial hypertension (PAH). Across PH groups, progressive right ventricular dysfunction is a shared consequence and a key determinant of survival. Approved therapies act primarily on the pulmonary vasculature and do not directly target the failing right ventricle.

Orai1, the pore-forming subunit of the CRAC channel, is upregulated in diseased pulmonary vasculature and cardiac tissue, where persistent CRAC channel signaling has been linked to proliferation, inflammation, vasoconstriction, fibrosis, and remodeling. In preclinical PH models, CRAC channel inhibition has been observed to improve the structure and function of the pulmonary vasculature and both ventricles.^{2, 3}

CalciMedica’s planned Phase 1b proof-of-concept trial will evaluate Auxora in patients with PH and is intended to generate initial clinical evidence supporting CRAC channel inhibition in this indication. Findings from the trial are also expected to inform the continued development of CM5480, the Company’s oral CRAC channel inhibitor for chronic dosing.

About Acute Pancreatitis
Acute pancreatitis is a serious inflammatory disease with no FDA-approved therapies and approximately 300,000 hospitalizations annually in the U.S.⁴ Respiratory failure is a major driver of mortality and intensive care utilization among patients with severe disease.

CalciMedica’s planned Phase 2b trial will evaluate new-onset severe respiratory failure as the primary endpoint, with multi-organ failure and time to medically indicated discharge as key secondary endpoints. The trial will also assess elevated lactate dehydrogenase as a potential enrichment marker to identify patients at increased risk of severe disease. Initiation of the trial is subject to additional financing.

About Auxora
Auxora™ (zegocractin) is CalciMedica’s proprietary intravenous CRAC channel inhibitor and most advanced pipeline candidate. It is designed to reduce inflammation by inhibiting CRAC channel-driven cytokine release in immune cells and to limit excessive calcium entry that may contribute to organ injury.

Auxora has been studied in more than 350 patients across conditions involving endothelial injury and respiratory failure:

• Acute pancreatitis: In the Phase 2b CARPO trial, Auxora produced a dose-dependent reduction in median time to solid food tolerance among hyper-inflamed patients. The medium and high dose groups also experienced a 100% reduction in new-onset severe respiratory failure compared with placebo.
• Pulmonary hypertension: CalciMedica plans to conduct a Phase 1b proof-of-concept trial, with data anticipated in mid-2027.
• COVID-19 pneumonia: In the Phase 2 CARDEA trial, Auxora reduced 30-day all-cause mortality by 56% compared with placebo.
• Acute kidney injury with respiratory failure: Auxora was evaluated in the Phase 2 KOURAGE trial, in which enrollment was paused in January 2026 following a mortality imbalance. No drug-related toxicity was identified. FDA subsequently reviewed a protocol amendment and interim safety data without comments or questions, allowing clinical development of Auxora to proceed. CalciMedica does not plan to restart KOURAGE at this time.

About CM5480
CM5480 is CalciMedica’s proprietary oral CRAC channel inhibitor designed for chronic dosing. By inhibiting Orai1-containing CRAC channels, it is intended to regulate abnormal calcium entry linked to vasoconstriction, pulmonary vascular remodeling, and right ventricular dysfunction.

In preclinical pulmonary hypertension models, CM5480 and other CRAC channel inhibitors have improved hemodynamics and reduced pulmonary vascular and right ventricular remodeling, both as monotherapy and in combination with vasodilators. In a rodent pulmonary artery banding model, which isolates cardiac effects from changes in the pulmonary vasculature, CM5480 also demonstrated evidence of direct protective activity in the right ventricle.

These findings support the potential of CM5480 as a differentiated therapy targeting key drivers of disease progression. CalciMedica is advancing CM5480 for pulmonary hypertension, including PAH and combined pre- and post-capillary pulmonary hypertension associated with heart failure with preserved ejection fraction, and anticipates submitting an IND in mid-2027.
