REDWOOD CITY and LA JOLLA, CA, November 21, 2022– Graybug Vision, Inc. (Nasdaq: GRAY) (Graybug) and CalciMedica Inc. (CalciMedica) today announced that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on further developing CalciMedica’s lead product candidate Auxora™, a proprietary, intravenous-formulated, small molecule calcium-release activated calcium (CRAC) channel inhibitor, to treat life-threatening inflammatory diseases, such as acute pancreatitis (AP), asparaginase-associated pancreatitis (AAP), acute kidney injury (AKI), and acute hypoxemic respiratory failure (AHRF), for which there are no currently approved therapies. Auxora, which modulates the immune response and protects against tissue cell injury, has been studied in four completed efficacy clinical trials, demonstrating positive and consistent clinical results, as well as a favorable safety profile. Subject to each company’s stockholder approval, the combined company is expected to trade on the Nasdaq Global Market.
With approximately $35 million in cash and cash equivalents anticipated from the combined company, including a private placement financing expected to occur immediately prior to the merger closing, the combined company is expected to have a cash runway into the second half of 2024, funding the advancement of Auxora in AP and AAP through clinical milestones in 2023. The proposed merger is expected to close in the first quarter of 2023.
“After completing a comprehensive strategic review, we determined that the proposed merger with CalciMedica would provide the best return for Graybug stockholders moving forward,” said Frederic Guerard, Pharm.D., Chief Executive Officer of Graybug. “The decision by our management and board of directors to select CalciMedica to be our merger partner will allow our stockholders to participate in a company with a strong clinical-stage pipeline poised to revolutionize treatment for large, underserved patient populations suffering from life-threatening inflammatory diseases worldwide.”
The combined company plans to advance the development of Auxora through multiple clinical trials and anticipates the following milestones in 2023:
- Results from an ongoing Phase 2b clinical trial (CARPO) in AP patients with systemic inflammatory response syndrome (SIRS) in second half of 2023 — CARPO is a randomized, double-blind, placebo-controlled, dose-ranging trial intended to establish efficacy in AP. 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, and organ failure. 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, including the lungs, and is responsible for much of the mortality seen in AP.Details of the CARPO trial are available on clinicaltrials.gov (NCT04681066).
- Results from an ongoing investigator-sponsored Phase 1/2 clinical trial (CRSPA) in pediatric patients who develop AAP as a result of treatment with asparaginase for their underlying acute lymphoblastic leukemia (ALL) in first half of 2023 — CRSPA is a Phase 1/2 trial being conducted in pediatric patients with AAP, which is acute pancreatitis resulting from the administration of asparaginase. Treatment with asparaginase triggers the development of AAP in 7-10% of patients with ALL,with more than half of those patients developing pancreatic necrosis. CalciMedica believes that the CRSPA trial has defined an optimal pediatric dose and plans to meet with the U.S. Food and Drug Administration in the first half of 2023 to determine the path forward for a potential accelerated approval of Auxora. Details of the CRSPA trial are available on clinicaltrials.gov (NCT04195347).
“I’m extremely pleased to announce this proposed merger with Graybug, which comes at a pivotal time for our company,” said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. “This transaction will provide us with the financial strength to advance the development of our lead candidate, Auxora, in life-threatening inflammatory illnesses. We have multiple value-driving milestones expected over the next 12 months, including data from our Phase 2b CARPO clinical trial in patients with AP and a potential path to accelerated approval for Auxora in AAP. At CalciMedica, we are focused on delivering novel therapies that target CRAC channel inhibition to underserved patients with life-threatening inflammatory diseases for which no approved therapies exist. This transaction serves as a significant next step in the advancement of our important mission.”
