A Safety and Efficacy Study of a One-time Intravitreal Injection of SAR446597 in Participants With Geographic Atrophy Secondary to Age-related Macular Degeneration
What this study is about
This is a sequential Phase 1/2, two-part, conducted at multiple hospitals study on safety, tolerability, and effectiveness of one-time intravitreal SAR446597 for the treatment of participants with Geographic Atrophy (GA) secondary to Age-related Macular Degeneration (AMD). The core phase duration will be approximately 2 years for each participant.
View original scientific description
This is a sequential Phase 1/2, two-part, multicenter study on safety, tolerability, and efficacy of one-time intravitreal SAR446597 for the treatment of participants with Geographic Atrophy (GA) secondary to Age-related Macular Degeneration (AMD). The core phase duration will be approximately 2 years for each participant. An Extended Follow-Up (EFU) phase of 3 years follows the core phase. The treatment is a one-time intravitreal injection of SAR446597 (or sham as applicable in Part II).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 60 years old or above
- Participants with diagnosis of GA secondary to age-related macular degeneration (AMD)
- Study eye with best corrected visual acuity (BCVA) ETDRS Snellen equivalent for dose escalation (Part I) between 20/40 and 20/320 and for expansion (Part II) equal or better than 20/200
- Study eye with GA lesion measuring between 2.5 and 17.5 mm2 for dose escalation (Part I) and between 2.5 and 14.0 mm2 for expansion (Part II). For multifocal disease, study eye with at least one single lesion of more than 1.25mm2 for both Part I and Part II
Exclusion criteria
- GA in the study eye caused by a disease different than AMD
- Presence of neovascularization or a history of treatment with an anti vascular endothelial growth factor agent in the study eye
- Any condition or treatment (ocular or systemic) or medical or surgical history in the study eye that may prevent visual acuity improvement or interfere with ocular safety or efficacy assessments
- Current or history of systemic complement targeting treatment in the past 12 months
- Use of ocular corticosteroids for 4 months (for ocular or periocular injections), 6 months (for intraocular implants) or 3 years (for long lasting intraocular implants) prior to screening in the study eye
- History of macular laser photocoagulation treatment, photodynamic- or thermotherapy or photo biomodulation in the study eye
- History of active ocular infection in the study eye in 6 months prior to screening
- Presence of active ocular or periocular infections
- Active uncontrolled glaucoma in the study eye
- History of uveitis or scleritis in either eye
- Previous gene therapy in either eye
- Any significant poorly controlled illness that would preclude study compliance and follow up The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
