SAN DIEGO, CA – August 12, 2024 – LENZ Therapeutics, Inc. (Nasdaq: LENZ or “LENZ” or the “Company”), a late clinical-stage biopharmaceutical company focused on developing the first and only aceclidine-based eye drop to improve near vision in people with presbyopia, today announced that the Company has submitted a New Drug Application (NDA) to U.S. Food and Drug Administration (FDA) for LNZ100 (an aceclidine-based ophthalmic solution) for the treatment of presbyopia, a condition impacting an estimated 1.8 billion people globally and 128 million people in the United States.

“The submission of our NDA for LNZ100 is a significant milestone for LENZ and is a testament to the tremendous focus, execution and collaboration of our team,” said Eef Schimmelpennink, President and Chief Executive Officer of LENZ Therapeutics. “We believe LNZ100 has the potential to be best-in-class as a pupil-selective and long-acting therapeutic option for the treatment of presbyopia. We look forward to working alongside the FDA through this review process.”

The NDA submission is supported by positive data from the pivotal Phase 3 CLARITY study of LNZ100 for the treatment of presbyopia. In the Phase 3 CLARITY study LNZ100 achieved all primary and secondary near vision improvement endpoints with statistically significant three-lines or greater improvement in Best Corrected Distance Visual Acuity (BCDVA) at near, without losing one line or more in distance visual acuity, demonstrating LNZ100 was well tolerated with no serious treatment-related adverse events observed in the over 30,000 treatment days monitored in the CLARITY study.

The FDA has a 60-day filing review period to determine whether the NDA submission is complete and acceptable for review.
