Regulatory News:

Lysogene (FR0013233475 – LYS), a phase 3 gene therapy platform Company targeting central nervous system (CNS) diseases, today announced its 2020 full-year results, approved by the Board of Directors on 30 March 2021. Audit procedures on the Company’s 2020 financial statements were completed by the Company’s statutory auditors.

Karen Aiach, Founder, Chairman and Chief Executive Officer of Lysogene said: “2020 has been marked by challenges of a new sort with the COVID-19 pandemic, and I want to warmly thank our employees, partners and providers for their resilience during these tough times. Despite this new environment, Lysogene continued to execute on its two lead programs with positive biomarker data on LYS-SAF302 and regulatory clearances to initiate the clinical trial with LYS-GM101. In addition, we continued to expand our early-stage pipeline with a new collaboration with the Weizmann Institute for gene therapy approaches for neuronopathic Gaucher and Parkinson’s diseases. Eventually, we strengthened our balance sheet with a capital raise, welcoming new US investors providing further validation of our technology.” Karen Aiach added: “2021 is off to a good start, and this year will be marked by a sustained focus on executing on our clinical programs and further developing our pre-clinical pipeline.”

Total operating income reached €16.6 million in 2020, stable versus 2019, composed of:

  • €13.4 million revenues1 derived from the recognition of milestone payments from Sarepta in accordance with the IFRS 15 accounting standard;
  • €3.2 million in other operating income, mainly consisting of the Research Tax Credit.

Operating expenses reached €21.7 million in 2020, stable versus 2019, composed of:

  • Research and development expenses of €16.3 million, down €1.3 million from last year, due to a high basis of comparison in 2019 impacted by an accrual for a commercial dispute with an industrial partner and a milestone payment made to REGENXBIO in the first quarter of 2019 following the treatment of the first patient with LYS-SAF302. In addition, clinical expenses for the LYS-SAF302 drug candidate also decreased due to the end of patient enrollment and travel constraints related to COVID-19, offsetting increased expenses on the LYS-GM101 program;
  • General and Administrative expenses of €5.4 million, up €1.2 million compared to 2019. This increase mainly results from the full-year impact of the internalization of some key finance and business development functions. To support its growth, the Company also increased its legal and business development budgets, as well as its communication expenses with the redesign of its website.

The net financial result was close to null at (€0.01 million) in 2020, compared to €0.8 million in 2019. The 2019 financial gain resulted from positive interest rates and unrealized foreign exchange gains on the USD term accounts. In 2020, the Company no longer recorded such financial gain as it converted its USD term accounts into Euros to hedge against the negative evolution of the USD, considering that most of the Company's expenses are now denominated in Euros.

The net loss for the period was €5.1 million compared to €4.3 million in 2019.

As of December 31, 2020, the company’s net cash amounted to €18.8 million, recently strengthened by a €5.0 million State-Guaranteed Loan (PGE) received in February 2021. This cash position provides the Company with financial visibility until the second quarter of 2022.

Business update

LYS-SAF302 program

On 25 February 2020, the Company announced that the program was granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) after having previously received Orphan Drug Designations in the European Union in 2014 and in the US in 2015, as well as Rare Pediatric Disease Designation in the US.

The Company treated a total of 19 patients in the Phase 2/3 clinical trial with LYS-SAF302 in MPS IIIA (NCT03612869). Recruitment of the main cohort is completed, therefore it is not impacted by the clinical hold issued by FDA in June 2020. The Company is making encouraging progress in the collection and analysis of the information necessary to respond to the FDA’s questions.

The Company reported positive biomarker data demonstrating the biological activity of LYS-SAF302 at the WORLDSymposium™ 2021. In 9 patients analyzed, significant reductions in heparan sulfate concentrations in the cerebrospinal fluid (CSF) were observed 12 months after treatment. In addition, the abnormally high concentration of GM2 and GM3 gangliosides, considered possible contributors to neuronal damage in lysosomal storage diseases, was reduced in the CSF of patients at 12 months post-treatment.

LYS-GM101 program

On 30 March 2021, the Company obtained approval from the ANSM in France, after having received authorizations from the MHRA in the U.K. and the FDA in the U.S. earlier this year, to initiate the adaptive clinical trial with LYS-GM101 for the treatment of GM1 gangliosidosis (NCT04273269).

Lysogene is initiating its global, multi-center, single-arm, two-stage, adaptive-design clinical trial of LYS-GM101 in patients with a diagnosis of early or late infantile GM1 gangliosidosis. The clinical trial will include a safety phase and a confirmatory efficacy phase. The Company intends dosing a total of 16 patients, with dosage of the first patient expected in the first half of 2021.

In addition, Lysogene’s natural history video study in GM1 gangliosidosis (NCT04310163) has received IRB (Institutional Review Board) approval and has already successfully recruited 67% of participants.

Fragile X syndrome program

Lysogene is engaged in a discovery collaboration with the lab of Hervé Moine at the IGBMC Strasbourg and SATT Conectus. The aim of the collaboration is to explore the therapeutic potential in Fragile X syndrome (FXS) of an AAV vector carrying a modified form of diacylglycerol kinase kappa. Pre-clinical proof of concept studies in a mouse model of FXS are progressing as planned, with initial results expected this year.

Gaucher and Parkinson’s diseases

In June 2020, Lysogene has entered into a collaborative research agreement with Yeda, the commercial arm of the Weizmann Institute of Science, with the aim of developing a novel AAV gene therapy approach for neuronopathic Gaucher disease, Parkinson’s disease, and other diseases associated with mutations in the GBA1 gene. Initial results are expected by Q1 2022.

Capsid Discovery program

Lysogene is engaged in a discovery collaboration aiming at the development of novel AAV capsids with IRBM, a global partner research organization in Pomezia (Rome, Italy) with proven experience and track record in integrated neuroscience drug discovery. The collaboration is proceeding according to plan.

Impacts of COVID-19 on the Company’s activities

In the context of the Phase 2/3 study with LYS-SAF302, the organization of visits and the follow-up of patients was made more difficult, forcing the Company to submit urgent safety measures to the health authorities and to amend certain protocols. For instance, the Company had to reorganize some hospital visits of patients by involving new doctors and sending them to other hospitals. All these new arrangements have resulted in additional direct clinical costs for the Company.

In addition, the start of the clinical trial with LYS-GM101, initially planned for 2020, has been postponed to the first half of 2021 due to delays in the regulatory review processes. Despite this delay of several months, LYSOGENE had to bear the costs related to contractual payments of CRO fees and other service providers.

These additional clinical costs were offset by savings on travel expenses for all employees, which have been significantly reduced from March 2020.

Furthermore, since the beginning of the pandemic, the Company has strictly complied with government guidelines and recommendations. It is committed to preserving the integrity and safety of its employees, partners, patients, and their families.
