Freeline Reports Second Quarter 2022 Financial Results and Business Highlights

Six patients dosed in B-LIEVE trial of FLT180a in hemophilia B in four months and initial and emerging cohort one data reported, followed by NEJM publication of B-AMAZE long-term data

Continued progress in FLT190 in Fabry disease and FLT201 in Gaucher disease, with new country and site initiations paving the way for delivery of key milestones in both programs

Leadership team further strengthened by appointing new Chief People Officer

LONDON, August 9, 2022 – Freeline Therapeutics Holdings plc (Nasdaq: FRLN) today reported financial results and business highlights for the second quarter of 2022.

“In the second quarter, we continued to make progress in demonstrating the value of our portfolio of clinical programs and the strong foundation provided by our potent AAVS3 capsid. We dosed both the first and second cohorts in the B-LIEVE trial, a total of six patients, between March and June, and reported encouraging initial and emerging cohort one data in July,” said Michael Parini, Chief Executive Officer of Freeline. “In addition, with the recent publication of the B-AMAZE long-term follow-up data in NEJM and related broad media coverage highlighting the potential benefit for patients, our confidence in the strength of our foundational science is high and we look forward to extending the application of this strong scientific underpinning to our other clinical programs.”

“In this regard, we are bringing the same sense of urgency and strong executional focus exhibited in our FLT180a program to our lysosomal storage disease programs, initiating new trial sites in current and multiple additional countries and identifying and screening more eligible patients to advance our Phase 1/2 dose-finding trials of FLT201 in Gaucher disease and FLT190 in Fabry disease,” said Parini. “The increased focus on these programs positions us well to demonstrate their value as potential best-in-class and/or first-in-class gene therapy candidates in these debilitating diseases affecting significant patient populations.”

"We are advancing the evaluation of our strategic options for FLT180a for hemophilia B and are reviewing how to best streamline operations and prioritize our efforts on the highest value activities, including progressing FLT201 for Gaucher disease and FLT190 for Fabry disease and identifying additional research projects in new disease areas. Through these efforts, we are looking to improve our efficiency and extend our cash runway,” said Paul Schneider, Chief Financial Officer of Freeline. “We anticipate concluding this comprehensive review and executing on prioritized activities in the second half of this year as we remain focused on delivering value to patients with debilitating disease and shareholders alike.”

“Finally, we continued to strengthen Freeline’s leadership team by adding Nicole Jones as our new Chief People Officer,” said Michael Parini. “Nicole’s experience in talent development and attraction will be instrumental in advancing Freeline’s capabilities to position the company for long-term success.”

Program Updates

FLT180a in hemophilia B

Following completion of the dosing of cohort one in the Phase 1/2 dose-confirmation B-LIEVE trial in April, dosing of the second cohort was completed in June, using the same FLT180a dose (7.7e11 vg/kg) and proactive immune management as in the first cohort, consistent with the advice of the trial’s independent Data Monitoring Committee based on initial cohort one data.

Positive initial safety and efficacy data from the first B-LIEVE cohort were presented at the International Society on Thrombosis and Haemostasis (ISTH) Congress in London on July 10, and updates from that cohort and initial trends from the second cohort were reported the same day.

Positive long-term follow-up data from the Phase 1/2 dose-finding B-AMAZE trial of FLT180a were published in The New England Journal of Medicine (NEJM) on July 21.

The company expects to report updated safety and efficacy data from the B-LIEVE trial in the second half of the year while it evaluates strategic options for FLT180a, which include, but are not limited to, seeking a partner that would enable the continuation of FLT180a through Phase 3 development.

FLT190 in Fabry disease

Dosing in the second cohort (1.5e12 vg/kg) in the Phase 1/2 dose-finding MARVEL-1 trial and a further program update are expected in the second half of 2022.

FLT201 in Gaucher disease

Dosing in the Phase 1/2 dose-finding GALILEO-1 trial is expected in the second half of 2022 with initial safety and efficacy data expected to be reported in the first half of 2023.

Corporate Updates

Effective July 11, Nicole Jones, SPHR, became Freeline’s new Chief People Officer. Ms. Jones previously served as Head of Global Talent Management & Leadership Development at Merck and brings 25 years of industry experience in senior global Human Resources and talent management roles at companies including Alexion, Fidelity Investments and Raytheon. She holds a Master of Business Administration from Meredith College and a Bachelor of Science in Economics from North Carolina State University.

Freeline’s new CFO, Paul Schneider, joined the company on May 16, 2022, as announced in April.

Q2 2022 Financial Highlights

  1. Cash Position: Unrestricted cash and cash equivalents were $90.0 million as of June 30, 2022, as compared to $117.7 million as of year-end 2021. Freeline expects that its current level of cash and cash equivalents will enable the company to fund its operating expenses into the second half of 2023.
  2. Research and Development (R&D) Expenses: R&D expenses for the six months ended June 30, 2022 were $8 million, as compared to $48.1 million for the same period in 2021. The decrease of $9.3 million was primarily driven by decreases in spending for personnel expenses and non-cash share-based compensation expense in conjunction with both our reduction in force executed in 2022 as well as executive turnover. In addition, the company saw a decrease in expenditures for our FLT201 program, mainly due to a decrease in CMO fees for clinical materials which were manufactured in 2021 to support the ongoing trial, and in spending related to FLT210, our former therapy candidate for the treatment of hemophilia A which was discontinued in 2021. These decreases were partially offset by an increase primarily for FLT190 related to ongoing clinical trial costs for the Phase 1/2 MARVEL-1 clinical trial in 2022.
  3. General and Administrative (G&A) Expenses: G&A expenses decreased by $8.3 million to $16.3 million for the six months ended June 30, 2022, as compared to $24.6 million for the same period in 2021. The decrease was driven by lower personnel expenses and related non-cash share-based compensation expenses, legal and professional fees, and other related expenses.
  4. As of June 30, 2022, the Company had 64,972,301 ordinary shares outstanding.
