Histogen Reports Fourth Quarter and Year-End 2021 Financial Results and Provides Business Update

Last Updated on March 10, 2022 by GlobeNewsWire

SAN DIEGO, March 10, 2022 (GLOBE NEWSWIRE) — Histogen Inc. (NASDAQ: HSTO), a clinical-stage therapeutics company focused on developing both restorative therapeutics and pan-caspase and caspase selective inhibitors focused on treatments for infectious and inflammatory diseases, today reported financial results for the fourth quarter and year ended December 31, 2021 and provided an update on its clinical pipeline and other corporate developments.

“We have a diverse pipeline of biologics and small molecule product candidates that we believe address large unmet market needs,” said Steven J. Mento, Ph.D., Interim President and Chief Executive Officer. “Looking ahead, we will continue to focus on clinical execution with HST-003 in cartilage repair, and emricasan in COVID-19 with our partner Amerimmune while we explore the feasibility of testing emricasan in animal studies for methicillin resistant staphylococcus aureus infections (MRSA), and continue to evaluate our caspase-1 inhibitors that impact the inflammasome pathway. These activities support our overarching goal of enhancing the lives of patients as we seek to build value for our shareholders.”

Highlights from the Fourth Quarter and Year Ended 2021 and Business Updates

HST-003 – In the second half of 2021, we initiated our Phase 1/2 clinical study of HST-003 to evaluate the safety and efficacy of human extracellular matrix (hECM) implanted within microfracture interstices and the cartilage defect in the knee to regenerate hyaline cartilage in combination with a microfracture procedure. We have experienced recruitment challenges due to both the specific nature of the study inclusion criteria and the impact of COVID-19 on the elective surgery environment. Additional qualified clinical sites have been added to help supplement recruitment and we will continue to evaluate the need to add more sites and study resources. We now anticipate top line results in the first half of 2023, assuming we complete enrollment in the fourth quarter of 2022.
HST-004 – Our initial preclinical research has shown that HST-004 stimulates stem cells from the spinal disc to proliferate and secrete aggrecan and collagen II, regenerate normal matrix and cell tissue structure and restores disc height. HST-004 was also shown to reduce inflammation and protease activity and upregulate aggrecan production in an ex vivo spinal disc model. In the second half of 2021, we initiated toxicology studies and other IND enabling activities for HST-004. However, due to pipeline program prioritization, we now anticipate filing IND for HST-004 in the second half of 2023.
Emricasan COVID-19 – In June 2021, we, jointly with Amerimmune LLC (“Amerimmune”), announced positive results from the Phase 1 study of emricasan in mild symptomatic COVID-19 patients. Emricasan was shown to be safe and well-tolerated during the 14 days of dosing and at the day 45 follow-up, as compared to placebo with no reports of serious adverse events. Patients who completed treatment with emricasan showed a statistically significant complete resolution of the symptoms most commonly associated in mild COVID-19, such as a cough, headache, and fatigue at day 7 which continued through day 45. No patients in the placebo arm experienced COVID-19 associated symptom resolution at any time point out to day 14. The mean number of days to recovery for patients in the emricasan arm was 4.8 days compared to 37.5 days in the placebo arm (p=0.001). In March 2022, we filed our demand for arbitration (“Arbitration Demand”) as we believe that Amerimmune has failed to undertake commercially reasonable efforts toward conducting and completing the Phase 2 study as required by the Collaborative Development and Commercialization Agreement that we previously entered into with Amerimmune (the “Collaborative Agreement”). As part of our Arbitration Demand, we are seeking a declaratory judgement from the arbitrator to terminate the Collaborative Agreement, which would result in us regaining all rights that we licensed to Amerimmune under the Collaborative Agreement. In such event, we intend to conduct and complete the Phase 2 study independently. If the Collaborative Agreement is not terminated, we will likely continue to jointly develop emricasan pursuant to the terms of the Collaborative Agreement. In either case, we anticipate a Phase 2 study could be initiated in the second half of 2022.
Emricasan MRSA – We are exploring the feasibility of testing emricasan in animal studies of other infectious diseases, initially focused on methicillin-resistant staphylococcus aureus (“MRSA”). We anticipate completing the feasibility assessment in the second half of 2022.
CEO Transition – In November of 2021, the board appointed Steven J. Mento, Ph.D. as Executive Chairman and Interim President and Chief Executive Officer.

Fourth Quarter and Full-Year 2021 Financial Highlights

Fourth Quarter Ended December 31, 2021 and 2020

Product and Service Revenues for the three months ended December 31, 2021 and 2020 were $0 and $0.5 million, respectively. The decrease of $0.5 million was due to fulfillment timing of CCM supply orders to Allergan PLC (“Allergan”). Our obligation to supply CCM to Allergan was satisfied in 2021, and we have no additional purchase orders with Allergan for fulfillment.

Cost of revenues for the three months ended December 31, 2021 and 2020, we recognized cost of product revenue of $0 and $0.3 million, respectively. The decrease of $0.3 million for the three months ended December 31, 2021 as compared to the three months ended December 31, 2020 was due to the decrease in product sales to Allergan.

Research and development expenses for the three months ended December 31, 2021 and 2020 were $1.6 million and $1.9 million, respectively. The decrease of $0.3 million for the three months ended December 31, 2021 as compared to the three months ended December 31, 2020 was primarily due to decreases related to personnel related expenses.

General and administrative expenses for the three months ended December 31, 2021 and 2020 were $1.5 million and $1.8 million, respectively. The $0.3 million decrease for the three months ended December 31, 2021 as compared to the three months ended December 31, 2020 was primarily due to decrease in personnel related expenses and rent expense decrease, partially offset by an increase in legal and other administrative expenses.

Twelve Months Ended December 31, 2021 and 2020

Revenues

For the years ended December 31, 2021 and 2020, we recognized license revenues of $27 thousand and $0.9 million, respectively. The revenue recognized in both periods is associated with the Allergan Agreements. During the period ended December 31, 2021, $19 thousand of deferred revenue was recognized in relation to the Potential Future Improvements remaining performance obligation currently being amortized over the remaining 9-year patent life. The year-over-year decrease is primarily attributable to the recognition of the allocated proceeds received upon the transfer of the expanded license to Allergan in January 2020.

For the years ended December 31, 2021 and 2020, we recognized product revenues of $0.9 million and $0.8 million, respectively. The increase of $0.1 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020 was due to a larger quantity of CCM sales to Allergan.

Grant revenue for the years ended December 31, 2021 and 2020 was $0.1 million and $0, respectively, all of which was related to an NSF research grant awarded to us in 2017. In March 2021, the Company completed all obligations under the NSF development grant and, as such, no longer generates any revenues in connection with the research and development grant.

For the year ended December 31, 2020, we recognized professional services revenue of $0.3 million, related to the transfer of certain technology and know-how, which was completed during 2020. As such, no additional professional services revenue was recognized during the year ended December 31, 2021.

Cost of Revenues

Cost of revenues for the years ended December 31, 2021 and 2020 were $0.2 million and $0.7 million, respectively. The decrease of $0.5 million for the year ended December 31, 2021 as compared to the year ended December 31, 2020 was primarily due to the sale of CCM to Allergan in September 2021 that was originally designated for research and development purposes and therefore had no cost of goods associated with it, and costs related to scrapped inventory.

For the years ended December 31, 2021 and 2020, we recognized costs of professional services of $0 and $0.3 million, respectively, related to the completion of technology transfer obligations of Histogen under the Allergan Agreements

In-process research and development expenses were $7.1 million for the year ended December 31, 2020 for in-process research and development acquired in connection with the Merger in May of 2020.

Research and development expenses for the years ended December 31, 2021 and 2020 were $8.5 million and $6.2 million, respectively. The increase of $2.3 million for the year ended December 31, 2021, as compared to the year ended December 31, 2020 was primarily due to increases in development costs of our clinical and pre-clinical product candidates and personnel related expenses, partially offset by $0.7 million in qualifying reimbursable expenses in connection with the DoD grant.

General and administrative expenses for the years ended December 31, 2021 and 2020 were $7.8 million and $6.6 million, respectively. This increase of $1.2 million for the year ended December 31, 2021 as compared to the year ended December 31, 2020 was primarily due to increases in personnel related expenses, legal fees and insurance costs.

Cash and cash equivalents as of December 31, 2021 were $18.7 million. Histogen believes that its existing cash and cash equivalents and cash inflow from operations will be sufficient to meet Histogen’s anticipated cash needs into the second quarter of 2023.
