BALA CYNWYD, Pa., Aug. 10, 2023 (GLOBE NEWSWIRE) — Larimar Therapeutics, Inc. (“Larimar”) (Nasdaq: LRMR), a clinical-stage biotechnology company focused on developing treatments for complex rare diseases, today reported its second quarter operating and financial results.

“Advancing our 50 mg cohort in our Phase 2 study and initiating our OLE study following FDA review of unblinded Phase 2 data from our 25 mg cohort are major advances in the development of CTI-1601 as potentially the first therapy designed to increase frataxin levels and address the underlying deficiency driving FA’s devastating clinical course,” said Carole Ben-Maimon, MD, President, and Chief Executive Officer of Larimar. “We are pleased to see that 25 mg was generally well tolerated and increased frataxin levels when dosed daily for 14 days. We are also very excited to now be able to initiate long-term dosing in the OLE trial in patients who participated in our Phase 1 or Phase 2 studies. The ability to follow patients in a long-term study that will assess increases in frataxin over months is very important to moving the development program forward.”

Dr. Ben-Maimon continued, “As we look ahead, we are focused on initiating our 50 mg cohort shortly, and plan to initiate our OLE trial in the first quarter of 2024. We expect to report top-line safety, pharmacokinetic, and frataxin data from the 50 mg cohort of our Phase 2 trial in the first half of 2024, and interim data from the OLE trial in the fourth quarter of 2024. Importantly, these trials will inform our future dose and dose regimen selection, as well as help to explore the long-term safety and pharmacokinetic and pharmacodynamic profiles of CTI-1601. With these key milestones ahead of us, coupled with our robust clinical dataset, we believe we are well-positioned to further advance the development of CTI-1601, with its unique mechanism of action and potential to be disease modifying for patients with FA.”

Second Quarter and Subsequent Highlights

• In July 2023, following FDA review of unblinded safety, pharmacokinetic, and frataxin data from the Phase 2 trial’s 25 mg cohort, Larimar received FDA clearance to initiate both a 50 mg cohort in the Phase 2 dose exploration trial evaluating CTI-1601 for FA and an OLE trial. Initiation of additional U.S. clinical trials are contingent on FDA review of Phase 2 data from the 50 mg cohort and any available data from the OLE due to the partial clinical hold.
• In May 2023, Larimar announced top-line data from the 25 mg cohort of its ongoing Phase 2, four-week, placebo-controlled, dose exploration trial of CTI-1601 for the treatment of FA. Data from the 25 mg cohort demonstrated that daily subcutaneous injections of 25 mg CTI-1601 for 14 days were generally well-tolerated and led to increases in frataxin levels from baseline compared to placebo in all evaluated tissues (skin and buccal cells).
• In July 2023, Larimar strengthened its executive clinical leadership with the appointment of Russell “Rusty” Clayton, DO, as Chief Medical Officer. As one of Larimar’s closest advisors for the last 5 years, Dr. Clayton has attended every meeting between Larimar and the FDA and has been chair of Larimar’s Scientific Advisory Board since inception. Dr. Clayton succeeds former CMO Nancy M. Ruiz, MD following her retirement.
• In June 2023, Larimar joined the broad-market Russell 3000 Index with inclusion in the large-cap Russell 1000 Index or small-cap Russell 2000 Index and appropriate growth and value style indexes.

Research and development expenses for the second quarter of 2023 were $5.9 million compared to $5.6 million for the second quarter of 2022. The increase in research and development expenses was primarily driven by an increase of $0.5 million in test method development and optimization, an increase of $0.4 million in personnel related costs, an increase of $0.2 million in stock-based compensation expense associated with stock option grants made in 2022 and 2023, partially offset by a decrease of $1.1 million in clinical supply manufacturing costs.

General and administrative expenses for the second quarter of 2023 were $3.7 million compared to $3.0 million for the second quarter of 2022. This increase was primarily driven by an increase of $0.3 million of professional fees primarily related to increased legal expense, an increase of $0.2 million in stock-based compensation expense associated with stock option grants made in 2022 and 2023 and an increase of $0.2 million in personnel related costs.

Research and development expenses for the first half of 2023 were $10.4 million compared to $11.5 million for the first half of 2022. The decrease in research and development expenses was primarily driven by a decrease of $1.5 million in clinical supply manufacturing costs, a decrease in assay development costs of $0.2 million partially offset by an increase of $0.5 million in personnel related costs, an increase of $0.3 million in stock-based compensation expense associated with stock option grants made in 2022 and 2023.
