ClinConnect Summary

This clinical trial is studying the effectiveness and safety of two types of low-dose atropine sulfate eye drops (0.01% and 0.02%) to see if they can help slow down the worsening of nearsightedness, known as myopia, in children and teenagers. The study will last for 96 weeks and will compare the eye drops to a placebo, which is a treatment that looks like the real drops but has no active ingredients. Children aged 6 to 12 years with mild to moderate myopia may be eligible to participate, as long as they meet certain criteria, such as having a specific degree of nearsightedness and not having any serious eye diseases.

Participants in the trial will receive either one of the eye drops or the placebo and will be monitored regularly to assess how well the drops are working and if there are any side effects. It’s important for families to know that the trial is currently recruiting participants, and anyone interested should discuss it with their legal guardian. The goal of this study is to find out if these low-dose eye drops can safely help manage myopia progression in children, which could be beneficial for their long-term eye health.

Eligibility criteria

• Inclusion Criteria:
• • 1. The legal guardian of the subject voluntarily signed the written informed consent, and the subject over 8 years is required to sign the written informed consent voluntarily.
• • 2. Patients with myopia aged 6 to 12 years, including cut-offs.
• • 3. The equivalent spherical refraction ranges from -1.00 D to -4.00 D (automatic optometry under a cycloplegia condition) in both myopia eyes at inclusion screening.
• • 4. The astigmatism of both eyes was ≤ 1.50 D under a cycloplegia condition at inclusion screening.
• • 5. The antimetropia (measured by equivalent spherical refraction) is \< 2.00 D at inclusion screening.
• • 6. Able to comply with study requirements, attend all study visits (including telephone visits), and be willing to receive random grouping of atropine treatment or placebo.
• Exclusion Criteria:
• • 1. Allergic to this product or its excipients.
• • 2. Suffering from eye diseases that may affect vision (e.g. lens diseases such as cataracts, glaucoma, fundus macular disease, keratopathy, uveitis, retinal detachment, severe vitreous opacity, etc., manifest strabismus, nystagmus, ocular acute inflammatory disease), history of recurrent chronic ocular inflammation, or any other ocular pathology (e.g., angular stenosis, shallow anterior chamber).
• • 3. Intraocular pressure of either eye is \> 21 mmHg or \<10 mmHg at screening.
• • 4. Use of low-concentration (0.05% and below) atropine sulfate eye drops (including various in-hospital preparations, except for test drugs) and orthokeratology lenses (OK lenses) within 6 months before the screening.
• • 5. Use of other myopia control methods such as instruments (multifocal glasses, progressive multifocal glasses, etc.), medications (the use of cycloplegic agents for examinations such as optometry is allowed), and others (including traditional Chinese medicine, auricular acupuncture, massage, accommodative flippers, red light therapy instrument, etc.) within 3 months before screening.
• • 6. Those who have participated in other clinical trials and received drug or medical device interventions within 3 months before screening.
• • 7. Systemic or topical use of drugs that affect the efficacy evaluation, such as anticholinergics: atropine, pirenzepine, etc., and cholinomimetics: pilocarpine, etc. within 1 week before screening.
• • 8. Combined with severe immune system disease, central nervous system disease, Down syndrome, asthma, cardiopulmonary insufficiency, liver and kidney dysfunction, etc.
• • 9. Surgical intervention (ocular or systemic) within 6 months before screening, or planned surgery during the study.
• • 10. Heart rate sustained (more than 10 minutes) greater than 120 beats/min at screening (after 10 minutes of rest if the ECG shows a heart rate greater than 120 beats per minute, the ECG should be retested 10 minutes later. If the retest result below 120 beats/min, the screening is successful; If the retest result is still \>120 beats/min, screening failed).
• • 11. Need for ocular use or systemic oral corticosteroids during the study. Intranasal, inhaled, topical cutaneous, intra-articular, perianal steroids, and short-term oral steroids (i.e., continuous use for \< 2 weeks).
• • 12. Other conditions that are considered unsuitable by the investigator.
