Freeline Reports Third Quarter 2022 Financial Results and Corporate Update

Entered into definitive agreement to sell CMC-focused German subsidiary and related IP for $25 million, while retaining rights to AAVS3 capsid and maintaining access to capabilities and technologies

Streamlining organization and extending cash runway into 2024

Prioritizing development of FLT201 in Gaucher disease and FLT190 in Fabry disease; ceasing investment in further development of FLT180a in hemophilia B

Updated data from first cohort of MARVEL-1 trial show FLT190 continues to be well-tolerated with sustained a-Gal A enzyme increases up to three years after dosing

LONDON, November 15, 2022 – Freeline Therapeutics Holdings plc (Nasdaq: FRLN) today reported financial results for the third quarter of 2022 and announced its decisions to sell its CMC-focused subsidiary in Germany to Ascend Gene and Cell Therapies Ltd., streamline its organization to increase efficiency and strengthen its financial position, and prioritize the development of FLT201 in Gaucher disease and FLT190 in Fabry disease. Additionally, Freeline announced updated data from the first cohort of the MARVEL-1 Phase 1/2 clinical trial of FLT190 showing encouraging safety and durability.

“The actions we announced today make Freeline a stronger and more agile company that is well-positioned to execute on our clinical programs and deliver on the promise of gene therapy for people with debilitating chronic diseases,” said Michael Parini, Chief Executive Officer of Freeline. “Prioritizing FLT201 for Gaucher disease and FLT190 for Fabry disease allows us to focus on programs that we believe have the greatest potential to benefit patients and drive value for shareholders. By streamlining the organization, selling our German subsidiary and moving to a flexible partnership model for CMC, we are also extending our cash runway through key data readouts and enhancing our ability to achieve our near- and long-term goals.”

Selling German CMC Subsidiary and Partnering with Ascend

Freeline has entered into a definitive agreement to sell its subsidiary, Freeline Therapeutics GmbH, and certain related intellectual property to Ascend for $25 million, subject to purchase price adjustments. Ascend is a specialist biopharma contract development manufacturing organization (CDMO) with operations in the United Kingdom and the United States and has assembled a transatlantic group of investors, including Abingworth, Petrichor and Monograph Capital, to support building the company. Freeline Therapeutics GmbH specializes in CMC process development, analytics and AAV technologies. The entity has approximately 55 employees and leased facilities in Munich. The transaction is expected to close in the first quarter of 2023 subject to customary closing conditions, including receipt of regulatory approvals.

At closing, Freeline and Ascend will enter into an intellectual property agreement that will assign certain patents and know-how related to CMC capabilities and technologies to Ascend. Freeline will maintain its rights to its AAVS3 capsid, and the agreement will include a back-license to Freeline of the assigned rights necessary to develop and commercialize its current product candidates.

Freeline will also simultaneously enter into a transitional services agreement with Ascend that will allow Freeline to maintain flexible access to analytical and process development capabilities and dedicated personnel for a period of 18 months following the closing of the transaction. The agreement will include a guaranteed minimum spend by Freeline of approximately $7.9 million over that 18-month period.

Streamlining the Organization

Freeline completed a thorough financial and organizational assessment to prioritize key capabilities, increase efficiencies and reduce expenses. As a result, the company is reducing its US and UK workforce by approximately 30 employees. This reduction would bring Freeline’s headcount to approximately 100 employees by the end of 2022, including the transfer of the employees in Germany to Ascend as part of the sale of Freeline Therapeutics GmbH. 

Prioritizing Clinical Portfolio

As a result of a previously announced evaluation of strategic options for FLT180a, its investigational gene therapy for hemophilia B, Freeline has decided to focus its resources on FLT201 and FLT190, which have the potential to be first-in-class and/or best-in-class programs, and stop investment in further development of FLT180a without a partner. The clinical data to date support FLT180a’s potential to be an important treatment option for patients with hemophilia B, if approved, and efforts to seek a partner to potentially bring FLT180a into Phase 3 development are ongoing.

“We are highly committed to the patients treated in our clinical trials and will continue the follow-up on all patients in our B-AMAZE and B-LIEVE studies,” Parini said. “We want to thank the patients, investigators and clinical sites for their trust and participation. Their collective contributions have advanced the understanding of gene therapy for hemophilia B as well as other diseases.”

Durable α-Gal A Increases in Fabry Patients from First Cohort of MARVEL-1 Trial

Updated data from the first cohort of the MARVEL-1 dose-finding trial in Fabry disease shows that FLT190 continues to be well-tolerated and induced durable increases of α-galactosidase A (α-Gal A). People with classic Fabry disease have little to no functional α-Gal A enzyme, and FLT190 is an investigational AAV gene therapy designed to induce α-Gal A expression, with the aim of eliminating the need for enzyme replacement therapy (ERT). Data from the two patients treated in the first cohort at a dose of 7.5e11 vg/kg showed that as of August 2022:

  • Elevated α-Gal A levels have been sustained for up to three years in Patient 1 and one year in Patient 2, with Patient 2 continuing to remain off ERT.
  • FLT190 has been well-tolerated.
  • No long-term cardiac sequelae have been observed following the early and transient mild myocarditis in both patients. The myocarditis resolved on its own in both patients.

Freeline initiated dosing in the second cohort (1.5e12 vg/kg) in September 2022.

Anticipated Upcoming Clinical Milestones

Freeline remains on track for its previously disclosed milestones for FLT201 and FLT190.

FLT201 in Gaucher disease

  • Begin dosing patients in the GALILEO-1 Phase 1/2 dose-finding trial by the end of 2022
  • Report initial safety and efficacy data in first half of 2023
  • Report updated safety and efficacy data in the second half of 2023

FLT190 in Fabry disease

  • Report initial safety and efficacy data from the second cohort of MARVEL-1 in the first half of 2023

Q3 2022 Financial Results

  • Cash Position: Unrestricted cash and cash equivalents were $65.8 million as of September 30, 2022, compared to $117.7 million as of December 31, 2021. With the changes announced today, Freeline now expects that its current level of cash and cash equivalents, plus the anticipated proceeds from the sale of Freeline Therapeutics GmbH, will enable the company to fund its planned operations into 2024.
  • Research and Development (R&D) Expenses: R&D expenses for the nine months ended September 30, 2022, were $53.6 million, compared to $70.8 million for the same period in 2021.  The decrease of $17.2 million was driven primarily by lower personnel expenses and share-based compensation as a result of the company’s 2021 reduction in force. In addition, the company saw decreases in manufacturing activities related to FLT201, clinical trial costs related to FLT180a, and spending related to FLT210, its hemophilia A program that was discontinued in 2021. These decreases were partially offset by an increase in FLT190 spending related to ongoing clinical trial costs for the MARVEL-1 trial in 2022.
  • General and Administrative (G&A) Expenses: G&A expenses for the nine months ended September 30, 2022, were $25.0 million, compared to $37.2 million for the same period in 2021. The decrease of $12.2 million was driven primarily by lower personnel expenses and share-based compensation as a result of the company’s 2021 reduction in force, reduced legal and professional fees and other related expenses.
  • Net Loss: Net loss was $66.0 million, or $1.15 per share, for the nine months ended September 30, 2022, compared to a net loss of $105.7 million, or $2.96 per share, for the nine months ended September 30, 2021.
