​

ARLINGTON, Mass., March 29, 2024 – KALA BIO, Inc. (NASDAQ:KALA), a clinical-stage biopharmaceutical company dedicated to the research, development and commercialization of innovative therapies for rare and severe diseases of the eye, today reported financial results for the fourth quarter and full year ended December 31, 2023 and provided a corporate update.

​

“In 2023, we focused on clinical execution, advancing our Phase 2b CHASE trial of KPI-012 for the treatment of PCED. In March 2023, we announced positive safety data from the first cohort of patients, reinforcing the promising safety and tolerability profile of high dose KPI-012, and allowing us to progress into the multicenter, randomized, double-masked efficacy cohort, which we are targeting to read out by year-end 2024,” said Mark Iwicki, Chair and Chief Executive Officer of KALA BIO. “Based on its multifactorial mechanism of action, we believe KPI-012 may address a significant unmet need, potentially offering patients and physicians a highly differentiated product profile and the first therapy for PCED that addresses the multiple underlying etiologies of the disease. We look forward to topline data from the CHASE trial, as we work to establish KPI-012 as a safe, well-tolerated, easily administered and effective treatment for the nearly 100,000 patients living with PCED in the U.S.”

​

Fourth Quarter and Recent Business Highlights:

​

Development-Stage Pipeline:

KALA is advancing an innovative pipeline based on its proprietary mesenchymal stem cell secretome (MSC-S) platform. KALA believes the multifactorial mechanism of action of its MSC-S platform technology may enable it to generate products for a range of ocular orphan diseases and is evaluating the potential development of this technology for multiple rare, front- and back-of-the-eye diseases.

​

KPI-012 combines growth factors, protease inhibitors, matrix proteins and neurotrophic factors to potentially correct the impaired corneal healing that is an underlying etiology of multiple severe ocular diseases.

​

KALA is initially developing KPI-012 for the treatment of persistent corneal epithelial defect (PCED), a persistent, non-healing corneal defect or wound that is refractory to conventional treatments which, if left untreated, can lead to significant complications, including infection, corneal perforation/scarring and vision loss. PCED has an estimated incidence of approximately 100,000 patients in the U.S. and represents a sizeable market opportunity; there are currently no U.S. Food and Drug Administration (FDA)-approved prescription products with a broad indication for all underlying etiologies of PCED.

​

​

KALA is also evaluating the potential of KPI-012 for additional rare, front-of-the-eye diseases, such as Limbal Stem Cell Deficiency (LSCD) and other corneal diseases that threaten vision. LSCD is characterized by the loss or deficiency of limbal epithelial stem cells, which can result in recurrent epithelial breakdown, neovascularization, conjunctivalization,

inflammation and other sequalae that can lead to loss of corneal clarity and vision impairment. Like PCED, LSCD represents a substantial market opportunity, with an estimated incidence of 100,000 patients in the U.S.

​

KPI-014, KALA’s preclinical program to evaluate the utility of its MSC-S platform for inherited retinal degenerative diseases, contains neurotrophic factors, growth factors, anti-inflammatory or immune-modulatory factors and antioxidant inhibitors with the potential to protect and preserve retinal cell function. Secretomes have demonstrated a neuroprotective effect in both in vitro and in vivo models of retinal degeneration. KALA believes KPI-014 could offer a gene-agnostic approach for the treatment of rare inherited retinal diseases and has initiated preclinical studies to evaluate the utility of KPI-014 for conditions such as Retinitis Pigmentosa and Stargardt Disease.

​

Corporate:

In December 2023 and March 2024, KALA announced private placement financings with an institutional investor, priced at-the-market under Nasdaq rules. Aggregate gross proceeds from the financings were approximately $2.0 million and $8.6 million, respectively.

​

Financial Results:

​

Cash Position: As of December 31, 2023, KALA had cash and cash equivalents of $50.9 million, compared to $56.1 million as of September 30, 2023. This decrease reflects cash used in operations and gross proceeds of $2.0 million received from KALA’s December 2023 private placement financing. Based on its current plans, KALA anticipates that its cash resources as of December 31, 2023, together with gross proceeds of $8.6 million received from its March 2024 private placement financing and anticipated funding under the CIRM award, will enable it to fund operations into the third quarter of 2025.

About KALA BIO, Inc.

​

KALA is a clinical-stage biopharmaceutical company dedicated to the research, development and commercialization of innovative therapies for rare and severe diseases of the eye. KALA’s biologics-based investigational therapies utilize KALA’s proprietary mesenchymal stem cell secretome (MSC-S) platform. KALA’s lead product candidate, KPI-012, is a human MSC-S, which contains numerous human-derived biofactors, such as growth factors, protease inhibitors, matrix proteins and neurotrophic factors that can potentially correct the impaired corneal healing that is an underlying etiology of multiple severe ocular diseases. KPI-012 is currently in clinical development for the treatment of persistent corneal epithelial defect (PCED), a rare disease of impaired corneal healing, for which it has received Orphan Drug and Fast Track designations from the U.S. Food and Drug Administration. KALA is also targeting the potential development of KPI-012 for the treatment of Limbal Stem Cell Deficiency and other rare corneal diseases that threaten vision and has initiated preclinical studies to evaluate the potential utility of its MSC-S platform for retinal degenerative diseases, such as Retinitis Pigmentosa and Stargardt Disease.
