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
- All subjects with intermediate AMD diagnosis in one or both eyes will be considered, regardless the severity stage and subtype of disease in the other eye. High-risk iAMD (numerous large, confluent drusen covering ≥ 0.5 disk area, with or without pigmentary changes but having no evidence of GA or CNV) in the study eye Subjects can have either: (i) Bilateral high-risk iAMD, or (ii) High-risk iAMD in one eye with GA and/or CNV in the fellow eye.
Exclusion criteria
- Patient previously taking high dose Atorvastatin 80 mg
- Patients previously taking other statins than high dose atorvastatin, in whom primary care provider (PCP) feels cannot be safely moved to high dose atorvastatin or those in which high dose atorvastatin is deemed contraindicated by PCP
- Patients with known adverse reaction to statins
- Patients with severe renal disease or multiple comorbidities
- Age \>85 years
- Patients with concomitant use of cyclosporine
- Active uveitis;
- Ocular infection;
- Any retinopathy other than AMD;
- Media opacities;
- Refractive error equal or superior to 6 diopters (spherical equivalent);
- Any previous retina surgery;
- Other ocular surgery or intra-ocular procedure in the study eye (injection other than anti angiogenic injection, laser) within the 90 days prior to enrollment
Where
- Boston, Massachusetts
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.
