Boston, May 7, 2024 -- Entrada Therapeutics, Inc. (Nasdaq: TRDA) is a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines that engage intracellular targets that have long been considered inaccessible. The Company today reported financial results for the first quarter ended March 31, 2024, and highlighted recent business updates.

"The first quarter of 2024 was a period of significant clinical progress for Entrada. We initiated dosing for the fourth and final cohort of our Phase 1 clinical trial of ENTR-601-44 for DMD and our partner Vertex announced that enrollment and dosing are underway in their global Phase 1/2 clinical trial of VX-670 for DM1," said Dipal Doshi, Chief Executive Officer of Entrada Therapeutics. "With two neuromuscular programs from Entrada's development pipeline now in the clinic and a cash runway expected through the second quarter of 2026, we believe we are well positioned to execute on several important clinical milestones across our pipeline of intracellular therapeutic candidates in 2024 and beyond."

Recent Corporate Highlights

•The Company completed dosing for the first three cohorts and has initiated dosing for the fourth and final cohort of its Phase 1 clinical trial, ENTR-601-44-101, for the potential treatment of individuals with Duchenne muscular dystrophy (DMD) who are exon 44 skipping amenable. Entrada expects to report data from the clinical trial in October of 2024.

•The Company is on track to submit regulatory applications in the fourth quarter of 2024 to initiate independent global Phase 2 clinical development studies for ENTR-601-44 in patients with DMD who are exon 44 skipping amenable and ENTR-601-45 in patients with DMD who are exon 45 skipping amenable.

•Vertex announced that its U.S. Investigational New Drug Application (IND) for the Phase 1/2 clinical trial of VX-670 in people with myotonic dystrophy type 1 (DM1) has cleared, as have the Clinical Trial Applications (CTAs) in Canada, the U.K. and the EU, and the Clinical Trials Notification (CTN) in Australia. Vertex further noted that enrollment and dosing are underway.

•In March 2024, Entrada achieved a milestone under its global collaboration with Vertex related to the clinical advancement of Vertex's Phase 1/2 clinical trial of VX-670, which triggered a $75 million payment. The Company expects to receive this payment in the second quarter of 2024.The Company is eligible to receive up to

$485 million, inclusive of milestones achieved to date, for the successful achievement of certain research, development, regulatory and commercial milestones, and tiered royalties on future net sales for any products that may result from this collaboration agreement.

First Quarter 2024 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $327.4 million as of March 31, 2024, compared to $352.0 million as of December 31, 2023. Entrada anticipates that its cash, cash equivalents and marketable securities as of March 31, 2024, together with ongoing research support from Vertex and the clinical advancement milestone expected to be received in the second quarter of 2024, will be sufficient to extend its cash runway through the second quarter of 2026, supporting the Company's expansion and continued development of EEV therapeutic candidates targeting DMD and advance EEV-therapeutic candidates in indications beyond neuromuscular disease.

Collaboration Revenue: Collaboration revenue was $59.1 million for the first quarter of 2024, compared to $25.3 million for the same period in 2023. The increase was primarily a result of the clinical advancement milestone achieved in the first quarter of 2024.

Research & Development (R&D) Expenses: R&D expenses were $28.6 million for the first quarter of 2024, compared to $23.1 million for the same period in 2023. The increase was primarily due to the progression of the Company's ENTR-601-44 Phase 1 clinical trial, costs incurred for IND-enabling studies for ENTR-601-45 and ENTR-601-50 to support future clinical trials, additional platform investment, and higher personnel costs (including non-cash, stock-based compensation).

General & Administrative (G&A) Expenses: G&A expenses were $9.4 million for the first quarter of 2024, compared to $7.9 million for the same period in 2023. The increase was primarily due to higher personnel costs (including non-cash, stock-based compensation).

Net Income (Loss): Net income was $23.5 million for the first quarter of 2024, compared to a net loss of $(6.7) million for the same period in 2023.
