  • CORXEL and LENZ Therapeutics Announce Positive Topline Data from China Phase 3 Presbyopia Trial of LNZ100

Primary endpoint was met with 74% of participants dosed with LNZ100 achieving three-lines or greater improvement at 3 hours post treatment,and maintaining their optimal distance visual acuity (i.e., not losing 5 or more letters). The difference in efficacy was statistically significant in the LNZ100 treatment group compared to the vehicle group (p<0.0001)

Rapid onset and long duration shown with 69% of participants achieving three-lines or greater improvement at 30 minutes and 30% at 10 hours

91% of participants indicated they noticed an improvement in their near vision

LNZ100 could potentially be the best-in-class non-invasive treatment for presbyopia

SHANGHAI, China and SAN DIEGO, Oct. 27, 2024 (GLOBE NEWSWIRE) — Corxel Pharmaceuticals (CORXEL) and LENZ Therapeutics (Nasdaq: LENZ) today announced positive topline data from the Phase 3 JX07001 clinical trial of LNZ100 in patients with presbyopia in China. CORXEL is a leading biotech company committed to bringing innovative science and medicines to underserved patients with serious and life-threatening diseases. LENZ Therapeutics is a pre-commercial biopharmaceutical company focused on developing the first and only aceclidine-based eye drop to improve near vision in people with presbyopia.

In this China Phase 3 safety and efficacy trial, LNZ100 (1.75% aceclidine HCl) achieved the primary endpoint and key secondary endpoints, with statistically significant three-lines or greater improvement in Best Corrected Distance Visual Acuity (BCDVA) at near, and maintaining their optimal distance visual acuity (i.e., not losing 5 or more letters). More results showed (all p<0.0001):

  • Rapid onset: 84% and 69% achieved two-lines and three-lines or greater improvement at 30 minutes respectively.
  • 3 hours post treatment: 88% and 74% achieved two-lines and three-lines or greater improvement at 3 hours respectively,and maintained their optimal distance visual acuity (i.e., not losing 5 or more letters).
  • Long duration: 61% and 30% achieved two-lines and three-lines or greater improvement at 10 hours respectively.

LNZ100 was well-tolerated with no serious treatment-related adverse events observed in the trial.

The study was a Phase 3, multicenter, randomized, double-blind, vehicle-controlled study, including a 4-week efficacy study followed by a 5-month extension safety study, designed to evaluate the efficacy and safety of LNZ100 (an aceclidine-based ophthalmic solution) in participants with presbyopia. The objectives were to assess the potential of LNZ100 to improve near vision among Chinese presbyopia patients and to evaluate the efficacy and safety profiles.  The trial has enrolled 300 participants, with a broad enrollment criteria of between 45 and 75 years of age with a refractive range of -4.0D SE to +1.0D SE, including those who had undergone laser-assisted cornea refractive surgery/monofocal IOL implantation.

Professor Jia Qu, Principal Investigator and Co-Principal Investigator,Vice Chairman of Ophthalmology Branch, Chinese Medical Association, Director of optometry department, Wenzhou Medical University said: “we are very pleased with the results of the LNZ100 trial, particularly the significant efficacy and favorable safety profile of LNZ100 in patients with presbyopia, demonstrating an important advance in the field of presbyopia treatment in China. Currently, patients mainly rely on wearing eyeglasses as treatment for presbyopia. There is a large unmet need for non-invasive and reversible treatments. We expect that LNZ100 will fill this vacuum and become an innovative force in the treatment of presbyopia in China, providing more patients with the hope of clear vision.”

Professor Fan Lyu, Principal Investigator and Co-Principal Investigator,Head of optometry working-group under Ophthalmology Branch, Chinese Medical Association, Director of National Clinical Medical Research Centre for Eye Diseases said: “The main active ingredient of LNZ100, aceclidine, causes temporary pupil constriction, resulting in an optical effect that significantly extends the depth of focus and improves the quality of vision. The statistically significant data and clinically meaningful outcomes observed in the trials provide strong support for the efficacy and safety of LNZ100. We anticipate that LNZ100 will be a practical treatment option for a wide spectrum of patients and will have a favorable impact on paradigm shift of helping improve near-vision in the Chinese presbyopia population.

“We are especially grateful to all the hard-working and dedicated researchers, partner organizations and all the volunteers who participated in the study,” Sandy Mou, Board Executive Director and Chief Executive Officer of CORXEL, said. “The common goal is to benefit hundreds of millions of people around the world, to set an international leading research benchmark, and to introduce novel treatment concepts and potentially optimal products to China first, providing a safe and convenient treatment option for the vast number of presbyopia patients. Looking ahead, we will actively communicate and cooperate with drug regulatory authorities to expedite the submission and approval of LNZ100. We believe that LNZ100 will not only significantly improve patients’ vision and quality of life, but will also have a profound impact on the field of presbyopia treatment and research in China.”

“We would like to first congratulate the team at CORXEL for their effort in their Phase 3 clinical study in China.  We are pleased with the impressive and consistent performance demonstrated by LNZ100 in our collective studies, further validating the vision of targeting an ‘all eyes, all day’ solution,” said Eef Schimmelpennink, President and Chief Executive Officer of LENZ Therapeutics. “With this data, we believe LNZ100 has further enhanced its potential as a global therapy and is further on its path towards providing access to the estimated 400 million people with presbyopia in China.  This data signifies a tremendous joint effort between the CORXEL and LENZ teams and comes in rapid succession to the recent FDA acceptance of our New Drug Application for LNZ100 in the United States.”

About Presbyopia
Presbyopia is a physiological phenomenon associated with aging that results in a progressively worsening ability to see nearby objects clearly. It is caused by the gradual hardening of the lens. This results in a decline of the eye’s adjustment function, and the inability to focus the image of nearby objects on the retina, leading to a decline in near vision. Studies have shown that the onset of presbyopia typically occurs around the age of 38, reaching a prevalence rate of nearly 100 percent at the age of 52 in China. It is estimated that more than 400 million people in China suffer from presbyopia.  

Currently, the treatment options for presbyopia are very limited. Wearing glasses requires frequent removal and insertion, causing many inconveniences in work and life. Surgery, as an irreversible invasive operation, has a very limited acceptance. There are no approved drugs for the treatment of presbyopia in China and the medical need for non-invasive, safe, efficient and reversible treatments for presbyopia remains unsolved.  

About LNZ100
LNZ100 (aceclidine) eye drops are being developed by LENZ Therapeutics and CORXEL acquired the Greater China rights for the development and commercialization in April 2022. LNZ100 is formulated with aceclidine, a miotic, and designed to achieve optimal pupil diameter without impacting distance vision, a key limitation of other miotics. Miotics are compounds that cause pupil constriction, or miosis, creating a pinhole effect that enables better focus of incoming light from near objects onto the retina. Research has shown that a pupil diameter below two millimeters (2 mm) is optimal for presbyopia treatment and results in clinically meaningful improvement in near vision.

Unlike other miotics such as pilocarpine and carbachol, aceclidine’s mechanism of action is pupil-selective, meaning it can activate the iris sphincter muscle and cause miosis of the pupil to a diameter below 2 mm without overstimulating the ciliary muscles that can cause a myopic shift and impair distance vision. As a result, aceclidine does not require any remaining accommodation to improve near vision, broadening its benefits to older presbyopes whose lens has lost this capacity. Therefore, we expect that users may be able to benefit from treatment even as they age from mid-40s to well into their mid-70s and across a broad range of refractive errors, as demonstrated in clinical testing to date.
