Histogen Reports First Quarter 2023 Results and Provides Business Update
Received FDA Clearance of IND Application for Emricasan for the Treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSI)
Emricasan Treatment has Therapeutic Effect Against Bacterial Skin Infection in Mice
Signed Exclusive Intellectual Property License Agreement with Johns Hopkins University
Steven J. Mento Ph.D. Appointed President and CEO
SAN DIEGO, May 11, 2023 (GLOBE NEWSWIRE) -- Histogen Inc. (NASDAQ: 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 reported financial results for the first quarter ended March 31, 2023, and provided an update on its pipeline and other corporate developments.
“The team has done a fantastic job of executing on critical milestones that support the development of emricasan as a potential treatment for ABSSSI,” said Steven J. Mento, Ph.D., President and Chief Executive Officer. “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 Dr. Mento. “The previously reported positive results in the COVID clinical trial together with the compelling preclinical data in bacterial skin disease point to a potential broad opportunity for emricasan as a more generalized host-based immunotherapeutic treatment of both viral and bacterial infections without the risk of generating resistance.”
Highlights from the First Quarter and Business Updates
Emricasan ABSSSI – 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. This 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 treatment for up to two years, including a Phase 1 study in mild symptomatic COVID-19 patients to assess safety, tolerability, and preliminary efficacy.
In April 2023, we announced the online publication of an abstract describing our preclinical study in mice showing that emricasan has therapeutic effect against bacterial skin infections. In the study, the role of the irreversible pan-caspase inhibitor emricasan alone and in combination with a standard-of-care antibiotic, doxycycline, was examined as a potential host-directed immunotherapy against bacterial infections in a mouse model commonly used to test the effectiveness of the innate immune response. Mice in four groups; placebo, placebo plus doxycycline, emricasan plus doxycycline, and emricasan alone were treated orally twice daily for 7 days after intradermal injection of the established CA-MRSA strain USA300 of Staphylococcus aureus in mice. The results of the study show that: (1) emricasan alone reduced both lesion size and bacterial burden versus placebo (pExclusive Intellectual Property License Agreement with Johns Hopkins – In April 2023, we 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.
Steven J. Mento Ph.D. appointed President and CEO – In March 2023, Dr. Mento was appointed President and CEO. Dr. Mento served as Histogen’s Executive Chairman and Interim President and CEO from November of 2021 to March 2023 and as a member of our Board since July 2005. Dr. Mento was one of Conatus’ co-founders and served as Conatus’ President and Chief Executive Officer from July 2005 until the merger with Histogen. From July 2005 until December 2012, Dr. Mento also served as Chairman of Conatus’ Board of Directors. Dr. Mento has over 40 years of combined experience in the biotechnology and pharmaceutical industries serving in a broad range of senior executive and scientific positions. He previously served as President, Chief Executive Officer, and a member of the Board of Directors of Idun Pharmaceuticals prior to its sale in 2005 to Pfizer.
First Quarter 2023 Financial Highlights: Three Months Ended March 31, 2023 and 2022
Revenues for the three months ended March 31, 2023 and 2022, we recognized license revenue of $5 thousand and $3.8 million, respectively. The decrease in the current period is due to a one-time payment of $3.75 million received in March 2022 as consideration for execution of the Allergan Letter Agreement.
Research and development expenses for the three months ended March 31, 2023 and 2022 were $1.0 million and $1.9 million, respectively. The decrease of $0.9 million was primarily due to decreases in outsourced manufacturing facility expenses, personnel related expenses, and the number of clinical and preclinical candidates in development and corresponding reduction of costs.
General and administrative expenses for both the three months ended March 31, 2023 and 2022 were $2.5 million. While there was no difference in expense between the periods, the change in the type of expenses for the period ended March 31, 2023 as compared to March 31, 2022 was primarily increases in stock-based compensation, outside services, and rent expenses, offset by reductions in royalty expenses, legal, insurance, and personnel related expenses.
