Freeline Reports Full Year 2020 Financial Results and Business Highlights
Plans to have three AAV gene therapy programs in the clinic by year-end 2021
Data from FLT180a Phase 1/2 trial for Hemophilia B demonstrated potential for durable normalization of Factor IX activity
Strong 2020 year-end cash position of $230 million funds key upcoming clinical milestones
LONDON, March 31, 2021 – Freeline Therapeutics Holdings plc (Nasdaq: FRLN) (the “Company” or “Freeline”), a clinical-stage biotechnology company developing transformative gene therapies for patients suffering from inherited systemic debilitating diseases, today reported financial results for the full year 2020 and provided an update on recent business highlights.
“We are pleased with our current progress and aim to have three Freeline programs in the clinic by the end of 2021,” said Theresa Heggie, Chief Executive Officer of Freeline. “We are looking forward to initiation of the Phase 1/2 dose-confirmation study for our lead program, FLT180a for the treatment of Hemophilia B, later this year to confirm both the dose and the immune management regimen for our planned pivotal Phase 3 study. Importantly, the data from the Phase 1/2 dose-finding trial we completed last year demonstrated the potential of FLT180a to provide a functional cure through the durable normalization of Factor IX activity. We also plan to progress dose escalation for the Phase 1/2 clinical study of FLT190 for the treatment of Fabry disease during 2021. Additionally, we are on track to dose the first patient in our FLT201 program for the treatment of Type 1 Gaucher disease by the end of 2021.
“Each of our pipeline programs leverages the Freeline research and manufacturing platform, allowing development of novel AAV gene therapy candidates using optimized cassette design, rapid candidate screening and cutting-edge analytics,” continued Ms. Heggie. “We believe that our in-house protein engineering capabilities as well as our proprietary AAVS3 capsid are key differentiators for Freeline, allowing us to deliver high protein expression at low doses for enhanced efficacy and the potential to address diseases that are beyond the reach of first-generation AAV vectors.”
Key Pipeline and Operational Updates
Hemophilia B
| · | Reported data for FLT180a for the treatment of Hemophilia B from the Phase 1/2 dose-finding clinical trial with a minimum of six-month post-treatment data for all 10 patients, supporting the potential for FLT180a to provide a functional cure with full normalization of Factor IX (“FIX”) activity in the normal range of 50 to 150 percent. Long-term follow-up data has shown durable FIX activity, with up to three-year data in the earliest cohort. |
| · | Announced updated clinical development plan for FLT180a to address Chemistry, Manufacturing and Control (“CMC”) feedback from the U.S. Food & Drug Administration (“FDA”) relating to the characterization and comparability of the investigational drug product used in the Phase 1/2 dose-finding clinical trial that was produced at smaller scale, as compared to the current investigational drug product that is produced at commercial-scale. |
| · | Plan to initiate Phase 1/2 dose-confirmation trial for FLT180a by the end of 2021 to confirm both the dose and the immune management regimen for the planned pivotal Phase 3 clinical trial. The Company is targeting full enrollment of the Phase 1/2 dose-confirmation trial during the first half of 2022 and a six-month data readout by the end of 2022. |
| · | Plan to report up to four-year durability data for FLT180a from the Phase 1/2 dose-finding clinical trial by the end of 2021. |
Fabry Disease
| · | Reported preliminary data from Phase 1/2 dose-finding clinical trial evaluating the safety and efficacy of FLT190 for the treatment of Fabry disease, demonstrating that a single administration of a low dose of FLT190 was generally well-tolerated and led to a three to four-fold increase over baseline in plasma α-galactosidase A (“αGLA”) activity. This increase was achieved by week four, and the patient continues to show stable elevated GLA expression at 12 months post-treatment. |
| · | Plan to progress dose escalation for the FLT190 Phase 1/2 clinical trial during 2021. |
Gaucher Disease
| · | Filed a CTA for FLT201 for the treatment of Type 1 Gaucher disease with the UK Medicine and Healthcare products Regulatory Agency (“MHRA”). |
| · | Presented preclinical data at the 17th annual WORLD Symposium™ detailing the invention and characterization of β-glucocerebrosidase variant 85 (“GCasevar85”), which was developed in-house and is produced by the Company’s proprietary FLT201 gene therapy construct. |
| · | Presented preclinical data at the 17th annual WORLD Symposium™ demonstrating the potential of FLT201 to deliver sustained levels of GCasevar85 to tissues not sufficiently addressed by velaglucerase alfa, a standard-of-care enzyme replacement therapy (“ERT”) for Type 1 Gaucher disease. FLT201 data demonstrate increased plasma stability, a 20-fold longer half-life, enhanced tissue uptake and substrate reduction, illustrating the potential for FLT201 to offer significant improvements in clinical outcomes over existing standard of care. |
| · | Currently plan to commence clinical development of FLT201 by targeting initiation of first-in-human dose-finding trials by the end of 2021. |
Hemophilia A
| · | Presented an analysis of the CHESS II Study at the 14th Annual Congress of the European Association for Haemophilia and Allied Disorders (EAHAD), highlighting the significant burden of joint pain and bleeding in factor-treated patients with Hemophilia A and B. Data suggest that despite treatment, patients face significant unmet clinical needs including continued bleeds and poor underlying joint health. |
| · | Plan to complete preclinical proof-of-concept studies of the safety, efficacy and durability of FLT210 to support an IND filing in 2022. |
Platform Technology
| · | Presented data at the 12th Annual Protein and Antibody Engineering Summit (PEGS) demonstrating how the Company’s proprietary, leading-edge analytical technologies characterize |
its AAV product by determining the proportion of capsids containing full-length vector genomes versus shorter vector fragments.
| · | Plan to further develop programs that leverage the Company’s proprietary protein engineering and manufacturing capabilities. |
Corporate
Freeline continues to strengthen its leadership team, building on key appointments last year, which include Theresa Heggie as Chief Executive Officer and member of the Board, Julie Krop, M.D. as Chief Medical Officer and Mark Baldry as Chief Commercial Officer, with the recent appointment of Michael J. Parini as President and Chief Operating Officer. The Company also recently strengthened the Board with the appointment of Colin A. Love, who brings extensive experience in the manufacturing of complex biotechnology products.
The Company also announced today that Jan Thirkettle, Ph.D., Chief Development Officer, has decided to leave Freeline to pursue a new opportunity. Dr. Thirkettle will continue in his current role until June 30, 2021, to ensure a smooth transition of his responsibilities. The Company has begun an external search for Dr. Thirkettle’s replacement.
In 2020, Freeline closed an extended Series C financing with an additional $79 million of new capital, augmenting the initial 2019 Series C funding of $40 million. The Company also completed a successful Nasdaq IPO with net proceeds of $161.8 million.
2020 Financial Highlights
Freeline plans to begin reporting financial results on a quarterly basis in 2021.
Research and development (R&D) expenses for the year ended December 31, 2020 were $76.1 million, as compared to $47.0 million for the same period in 2019. The increase of $29.1 million was driven by an increased investment in activities related to the current and proposed clinical trials for FLT180a and FLT190, and overall research and development, which includes earlier pipeline programs, discovery and further development of the Freeline platform.
General and administrative (G&A) expenses for the year ended December 31, 2020 were $26.3 million, as compared to $16.6 million for the same period in 2019. The increase of $9.7 million is driven primarily by legal and professional fees related to financing activities, as well as an increase in headcount and related personnel costs.
Cash and cash equivalents were $230.0 million as of December 31, 2020, as compared to $73.7 million as of year-end 2019. Based on the Company’s current operating plan, Freeline expects that its current level of cash and cash equivalents will enable the Company to fund its operating expenses into the third quarter of 2022.
As of December 31, 2020, the Company had 35,854,945 ordinary shares outstanding.
