Histogen Inc. (HSTO) today announced that the company has signed an exclusive license agreement with Johns Hopkins University.
Licensed Patents Expected to Provide Freedom to Operate and Exclusivity for Emricasan
Pipeline Focus on Pan-Caspase and Caspase Selective Inhibitors for Infectious and Inflammatory Diseases
SAN DIEGO, April 03, 2023 (GLOBE NEWSWIRE) -- Histogen, Inc. (HSTO), a clinical-stage therapeutics company focused on developing potential first-in-class clinical and preclinical small molecule pan-caspase and caspase selective inhibitors that protect the body’s natural process to restore immune function, today announced that the company has signed an exclusive license agreement with Johns Hopkins University. The intellectual property associated with this license covers the use of emricasan for the treatment of disease in humans resulting from viral or bacterial infections (including, but not limited to, MRSA, VRSA, and SARS-CoV-2). The license agreement with Johns Hopkins is an instrumental addition to Histogen’s intellectual property portfolio. Rights to these patent applications, together with recently issued internal patents, are expected to provide freedom to operate and exclusivity worldwide to the Histogen’s entire caspase inhibitor portfolio.
“We believe that emricasan has the potential to treat infections in a different way; by protecting the competence of the human body’s immune system thereby restoring the body’s natural process to combat invading organisms,” stated Steven J. Mento, President and CEO of Histogen. “The World Health Organization (WHO) names antibiotic resistance as one of the biggest threats facing humanity. By focusing on optimizing the immune response, we believe that we have an opportunity to provide emricasan as a viable treatment option for physicians without the risk of generating antibiotic resistance. We look forward to the anticipated initiation of clinical development activities using emricasan for the treatment of acute bacterial skin and skin structure infections (ABSSSI) in the second half of 2023,” concluded Dr. Mento.
As announced previously, emricasan improved symptoms in patients infected with COVD-19 potentially employing a similar mechanism of protecting the competence of the immune system. Patients in the placebo arm who completed the study showed either delay or no symptom resolution for the duration of the study.
About Emricasan
Emricasan is an orally available pan-caspase inhibitor designed to reduce the activities of human caspases, which are enzymes that mediate inflammation and apoptosis. Emricasan has completed extensive toxicology testing including chronic toxicology and clean carcinogenicity testing. The drug candidate has previously been shown to be well tolerated in multiple clinical studies involving approximately 1,000 subjects employing multiple doses ranging from 1 mg to 500 mg orally with dosing for up to two years, including a Phase 1 study in mild symptomatic COVID-19 patients to assess safety, tolerability, and preliminary efficacy. Patients who completed treatment with emricasan had a complete resolution of the symptoms most commonly associated with mild COVID-19, such as cough, headache, and fatigue at day 7 and continued through day 45. Patients in the placebo arm who completed the study showed either delay or no symptom resolution for the duration of the study. Additionally, in the fourth quarter of 2022, we completed our pre-clinical evaluation of emricasan for the potential treatment of ABSSSI, including those related to MRSA, and anticipate initiating clinical development activities for the treatment of ABSSSI in the second half of 2023.
About Histogen Inc.
Histogen Inc. is a clinical-stage therapeutics company focused on developing potential first-in-class clinical and preclinical small molecule pan-caspase and caspase selective inhibitors that protect the body’s natural process to restore immune function. Currently, we are developing emricasan for ABSSSI as well evaluating its use for other infectious diseases. Our pipeline also includes novel preclinical product candidates including CTS-2090 and other proprietary caspase inhibitors, which are selective small molecule inhibitors of caspase-1 designed for the treatment of certain inflammatory diseases.
