CalciMedica Announces Presentation of Initial Data from the CRSPA Study of Auxora at the 65th Annual ASH Meeting & Exposition

Auxora™ showed a 53% reduction in days in hospital, a 40% reduction in intensive care unit (ICU) days and eliminated the need for total parenteral nutrition (TPN)

LA JOLLA, Calif., Nov. 2, 2023 /PRNewswire/ -- 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 diseases, today announced that there will be a presentation of data from the initial cohort of the CRSPA study of Auxora™ (zegocractin) in asparaginase-induced pancreatic toxicity (AIPT) in a poster presentation at the 65th Annual American Society of Hematology (ASH) Meeting & Exposition being held December 9-12, 2023 in San Diego, CA.

The data to be presented by the study sponsor highlights promising early results of the investigational use of Auxora™ in children with acute lymphoblastic leukemia (ALL) experiencing asparaginase-associated pancreatitis, also known as AIPT and referred to as AAP in the abstract. The presentation includes results from the first cohort consisting of nine patients from the CRSPA study. Eight of nine patients received a full regimen of 4 daily doses of Auxora™ and results from these patients are compared to a historical matched control group of 16 patients with complete imaging out of a total of 51 patients who developed pancreatitis in the Total Therapy XVI study (T16). These children were treated at St. Jude Children's Research Hospital ("SJCRH") and developed pancreatitis within 30 days of receiving asparaginase (e.g. ONCASPAR™ and RYLAYZE™), a nearly identical ALL treatment protocol as used in the CRSPA study.

The results showed that treatment with Auxora™ compared to the historical matched control group reduced the average number of days patients spent in the hospital from 13.4 to 6.3 days. Three control patients (18.8%) needed intensive care unit (ICU) care compared to one treated patient (12.5%), and the average number of days in the ICU was reduced from 5 to 3 days. Additionally, no CRSPA patients required total parenteral nutrition (TPN), compared to 68.8% in the historical matched control group. The matched control patients that required TPN needed 27 days of nutritional support on average. Based on the results from cohort 1 of CRSPA, a dose level 1 (30mg/m² on day 1 and 42mg/m² on days 2-4) has been established as the recommended dose (RP2D) of Auxora™ for children with ALL experiencing AIPT.

About AIPT and CRSPA
AIPT is an ultra-orphan indication affecting 300-400 patients in the US each year. One of the mainstays of therapy in pediatric ALL patients is asparaginase (e.g. ONCASPAR™ and RYLAYZE™), an enzyme that degrades the amino acid asparagine, which is essential for the leukemic cells to survive. However, the administration of asparaginase triggers the development of AAP or AIPT in 7-10% of patients, including the over 4,000 pediatric ALL patients treated per year in the United States, with similar numbers in Europe. The first cohort in the dose-finding part of the CRSPA study consisting of 9 patients has been completed at SJCRH and investigators believe that an optimal pediatric dose for Auxora™ in this setting has been defined. The study has continued to enroll patients beyond the initial 9 patient cohort and is being expanded to additional sites. The full study plans for 24 patients at the optimal dose. Details of the CRSPA study 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 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. CalciMedica is currently conducting a Phase 2b trial in 216 patients called CARPO for acute pancreatitis (AP) with systemic inflammatory response syndrome (SIRS), with topline data expected in the first half of 2024. Additional data from the Phase 1/2 CRSPA AIPT study is expected by 2H 2024. A Phase 2 study in acute kidney injury (AKI) is planned for early 2024. CalciMedica was founded by scientists from Torrey Pines Therapeutics and the Harvard CBR Institute for Biomedical Research, and is headquartered in La Jolla, CA.
