Item 7.01. | Regulation FD Disclosure. |
On June 27, 2024, CalciMedica, Inc. (the “Company”) issued a press release announcing topline data from the Phase 2b CARPO trial of Auxora in acute pancreatitis (“AP”). A copy of the press release is attached hereto as Exhibit 99.1.
Included as Exhibit 99.2 to this Form 8-K is a slide presentation titled Developing Novel Therapies for Acute Inflammatory and Immunologic Diseases: CARPO Trial Topline Results dated June 27, 2024, that is incorporated herein by reference. The Company intends to utilize this presentation and its contents in various meetings with securities analysts, investors and others, including during a conference call and live webcast with the investment community on June 27, 2024, at 8:30 a.m. Eastern Time.
The information in this Item 7.01, including the attached Exhibits 99.1 and 99.2, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing made by the Company under the Securities Act of 1933, as amended, or the Exchange Act.
On January 27, 2024, the Company announced positive topline data from CARPO, the Company’s international, randomized, double-blind, placebo-controlled, dose-ranging Phase 2b trial evaluating Auxora for the treatment of AP with accompanying systemic inflammatory response syndrome (“SIRS”).
The Phase 2b CARPO trial intended to establish Auxora’s dose-response and efficacy in AP with accompanying SIRS. The trial reached its target enrollment of 216. Patients were randomized into four groups to receive either high 2.0 mg/kg dose (n=53), medium 1.0 mg/kg dose (n=56) or low 0.5 mg/kg dose (n=52) of Auxora or a matched dose of placebo (n=53) intravenously every 24 hours for a total of three doses. Treatment and observation of patients continued for 30 days. Patients were stratified by baseline hematocrit, a biomarker for inflammation severity, so that efficacy in a pre-specified hyper-inflamed sub-group of patients could be evaluated. These patients represented approximately 43% of the patients enrolled (2.0 mg/kg, n=23; 1.0 mg/kg, n=25; 0.5 mg/kg, n=24; and placebo, n=20). Patients were well-matched for all baseline characteristics with the exception that the placebo group had approximately 12% lower proportion of hyper-inflamed patients than the study overall.
Summary Efficacy Data
The Phase 2b CARPO trial met its study objective by showing a dose response for time to solid food tolerance as well as other clinical endpoints. The primary endpoint of median time to solid food tolerance in the pre-specified subgroup of patients with hyper-inflammatory AP showed a statistically significant dose response with placebo patients requiring 4.7 days to tolerate solid food and patients in the high dose group showing a 1.9 day improvement (41.0% relative risk reduction) when compared to placebo, the medium dose group showing a 2.1 day improvement (43.6% relative risk reduction) and the low dose group showing a 1.5 day improvement (31.0% relative risk reduction). In patients without hyper-inflammatory AP, Auxora did not show a measurable benefit due to the patients tolerating solid food relatively quickly in all treatment groups.
Additionally, Auxora demonstrated a statistically significant dose response in reduction of severe organ failure which was defined as respiratory failure requiring invasive mechanical ventilation or 48 hours or more of high-flow nasal canula therapy, renal failure requiring renal replacement therapy, or cardiovascular failure requiring the use of vasopressor or inotropic support for greater than 48 hours. Severe organ failure occurred in 3.8% of high dose patients, 3.6% of medium dose patients, 9.6% of low dose patients, and 9.4% of placebo patients, representing a 59.6% relative risk reduction for the high dose patients when compared to placebo and 61.7% risk reduction for the medium dose patients when compared to placebo.
