Rhea-AI Summary

CalciMedica has announced the first patient enrollment in its Phase 2 KOURAGE trial, testing Auxora™ for severe acute kidney injury (AKI) with acute hypoxemic respiratory failure (AHRF). This trial, supported by clinical and pre-clinical evidence, aims to enroll 150 patients. Participants will receive daily doses of Auxora or placebo and will be evaluated up to 30 days post-dosing. The study includes secondary endpoints like all-cause mortality and kidney function decline over 90 days. Previous trials and preclinical models have shown promising results for Auxora. Topline data are expected in 2025.

With AKI causing 3.7 million hospitalizations annually in the U.S., this trial could pave the way for a novel treatment in a field currently to supportive care.

  • First patient enrolled in Phase 2 KOURAGE trial testing Auxora for severe AKI.
  • Supported by clinical and preclinical evidence showing promising results.
  • 150 patients to be enrolled, providing a robust data set.
  • Focus on significant outcomes: ventilator-free days and kidney function.
  • Topline data expected in 2025, setting a clear timeline for results.
  • No immediate revenue or market impact as topline data expected only in 2025.
  • High risk of trial failure, common in early-stage biopharmaceutical studies.
  • Dependence on positive results to justify continued investment.

CalciMedica’s initiation of the Phase 2 trial for Auxora in severe acute kidney injury (AKI) is a promising development in a field where treatment options are notably limited. According to the current landscape, AKI leads to approximately 3.7 million hospitalizations annually in the U.S., highlighting a substantial unmet medical need. The fact that CalciMedica's Auxora has shown efficacy in preclinical and early human trials is important as it might offer a new therapeutic option.

However, the focus should be on clinical evidence supporting Auxora's efficacy and safety. While preclinical data and early-stage trials look promising, it is essential to note the inherent risk in clinical trials, especially in moving from early to mid-stage trials. The potential for a treatment breakthrough in AKI could revolutionize patient care, but investor expectations should be tempered by the understanding that clinical trials often face hurdles related to patient outcomes and regulatory approval.

Additionally, the use of randomized, double-blind, placebo-controlled study design adds robustness to this trial, a necessary step to ensure that results are both reliable and reproducible. If successful, this could lead to major advancements in treating AKI and possibly other related conditions.

The news regarding CalciMedica's Phase 2 trial initiation for Auxora signals a significant potential upside for the company. The trial's design and endpoints, including days alive without ventilation or dialysis and MAKE-90, are well-chosen to demonstrate the drug's value proposition. Topline data expected in 2025 means investors need to consider a long-term horizon.

From a financial standpoint, if Auxora succeeds in its trial phases, it could significantly boost CalciMedica's market valuation and open opportunities for partnerships or acquisitions. Given the current small market cap of CalciMedica, a positive outcome in these trials would substantially shift its financial landscape. However, the inherent risks of clinical trials should not be underestimated and investors should be prepared for the potential impact of trial setbacks on the company’s stock price.

Moreover, comparative analysis with other biopharma companies at a similar stage shows that successful data readouts often lead to substantial stock price appreciations. Investors should keep an eye on interim results, as these can provide early indicators of the trial’s success and influence stock movements ahead of final results.

Development of Auxora in AKI is supported by both clinical and pre-clinical evidence

Topline data expected in 2025

LA JOLLA, Calif., July 9, 2024 /PRNewswire/ -- CalciMedica Inc. ("CalciMedica" or the "Company") (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 announced that the first patient has been dosed in KOURAGE, the Company's Phase 2 trial evaluating Auxora™ for the treatment of severe acute kidney injury (AKI) with associated acute hypoxemic respiratory failure (AHRF).

"AKI is a serious condition, causing about 3.7 million hospitalizations annually just in the United States," said Lakhmir Chawla, M.D., Clinical Professor of Medicine at University of California San Diego, Chief Medical Officer at ExThera Medical, and Chair of the KOURAGE Steering Committee. "Disease progression for patients with AKI can occur quickly, and those who reach Stage 2 and Stage 3 AKI face significant risk of mortality and serious morbidities such as respiratory failure. The current standard of care for these patients is limited to supportive therapy. With Auxora, CalciMedica continues to lay the foundation for a potentially revolutionary treatment for an underserved and often fatal disease."

"Auxora has shown promising data in preclinical models and prior human trials which highlight its potential as a therapeutic option for AKI, where none currently exists," said Glenn Chertow, M.D., Norman S. Coplon/ Satellite Healthcare Professor of Medicine, Professor of Epidemiology and Population Health and Health Policy at Stanford Medicine, and Member of the KOURAGE Steering Committee. "In KOURAGE, Auxora will be used to treat patients with established, moderate to severe AKI, and I look forward to reviewing the data in the coming year."

KOURAGE is a randomized, double-blind, placebo-controlled study expected to enroll approximately 150 patients with Stage 2 and 3 AKI who have AHRF and will randomize patients to receive 5 daily doses of Auxora or placebo. The study will assess patients up to day 30 following the final dosing to evaluate the number of days alive without the need for a ventilator or dialysis. The study's secondary endpoints will include a composite measure of all-cause mortality, decline in estimated glomerular filtration rate (eGFR) and the occurrence of dialysis over a 90-day period, also known as MAKE-90 (Major Adverse Kidney Events at 90 days). Topline data from KOURAGE are expected in 2025.

"Our CARDEA trial revealed that treatment of severe and critical COVID-19 pneumonia patients with Auxora reduced the reported incidence of AKI and improved the survival of patients with kidney disease," said Sudarshan Hebbar, M.D., Chief Medical Officer of CalciMedica. "We demonstrated the potential benefits of Auxora in an ischemia reperfusion model of AKI that showed that the therapeutic treatment of AKI with Auxora improved kidney function as measured by estimated glomerular filtration rate and enhanced survival. These results were presented at the 29th International Conference on Advances in Critical Care Nephrology that was held in March of this year. These data contribute to the growing body of evidence supporting Auxora as a potential treatment for various acute and critical illnesses."

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 immune system cells, endothelium cells and pancreatic acinar 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 acute pancreatitis (AP) with accompanying systemic inflammatory response syndrome (SIRS), called CARPO, (ii) a Phase 2 trial in acute kidney injury (AKI) with associated acute hypoxemic respiratory failure (AHRF), called KOURAGE, and (iii) an investigator-sponsored Phase 1/2 trial, called CRSPA, being conducted in pediatric patients with asparaginase-induced pancreatic toxicity (AIPT) as a side effect of pediatric acute lymphoblastic leukemia treatment with asparaginase. There are currently no approved therapies to treat either AP, AKI 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 respiratory distress syndrome.

KOURAGE is a randomized, double-blind, placebo-controlled study that will evaluate 150 patients with Stage 2 and 3 AKI who have AHRF and are receiving oxygen by non-invasive mechanical ventilation, high flow nasal cannula or intermittent mandatory ventilation (IMV). AKI denotes a sudden reduction in kidney function, the organ's ability to clean and filter the blood. AKI can result as a complication of other serious illnesses such as sepsis, respiratory infections and failure, acute pancreatitis, trauma, surgery and burns. There are approximately 3.7 million patients hospitalized with AKI in the United States each year with approximately 1.1 million advancing to Stage 2 and Stage 3 AKI, over half of whom have associated AHRF. The risk of serious morbidities and mortality is significant for advanced Stage 2 and Stage 3 AKI patients. There are currently no approved therapies for AKI.
