A study about the safety of ASP3021 eye injections and if they help people in Japan with vision loss from age-related macular degeneration, Trial ID 3021-CL-3001

Study summary

Age-related macular degeneration (AMD) is an eye disease which causes people to lose their vision over time. AMD damages the macula, which is in the middle of the retina - the light sensitive part at the back of the eye. In AMD, the cells in the macula die over time, usually over several years, leading to vision loss. When AMD gets worse, it can turn into either geographic atrophy (GA), neovascular AMD, or both.

This study is for people in Japan of 40 years of age or older, who have geographic atrophy.

The main aim of this study is to collect information about the safety of ASP3021 and how well people tolerate treatment with ASP3021.

During the study, people will receive monthly injections of ASP3021 for 12 months. ASP3021 is given by injection into the affected eye. This procedure is called an intravitreal injection.

People will be in the study for about 1 year. People will visit their study clinic several times for health checks.

Participant has GA in part within 1500 microns from the fovea center point.
Participant has GA that must be able to be photographed in its entirety.
Participant has best corrected visual acuity (BCVA) between 20/25 and 20/320, inclusive.
Participant has clear ocular media and adequate pupillary dilatation in both eyes to allow for all imaging procedures, including good quality stereoscopic fundus photography and FAF.
Participant has intraocular pressure (IOP) of ≤ 21 mmHg or less.
Female participant is not pregnant and at least 1 of the following conditions apply:
- Not a women of childbearing potential (WOCBP).
- WOCBP who has a negative serum pregnancy test at screening with a medical interview and agrees to follow the contraceptive guidance from the time of informed consent through at least 40 days after final study intervention administration.
Female participant must not be breastfeeding or lactating starting at screening and throughout the investigational period and for 40 days after final study intervention administration.
Female participant must not donate ova starting at first administration of study intervention and throughout the investigational period and for 40 days after final study intervention administration.
Male participant must agree to use contraception with female partner(s) of childbearing potential (including breastfeeding partner) throughout the treatment period and for 40 days after final study intervention administration.

Frequently Asked Questions

Are clinical trials only for people with advanced cancer?

While some clinical trials may focus on more advanced cancers, many trials are open to patients at various stages of their cancer. Each study has rules about who can take part. For example, only patients in a certain age group or those who have a certain type of tumor may be able to join.

Will I have to stop my current treatment to participate in a clinical trial?

Sometimes researchers want participants to keep taking their current treatments during a clinical trial. Other times, you may need to stop your current treatments for a while. If the investigational treatment doesn't work, you can usually go back to your original treatment plan.

Should I be worried about getting a placebo?

In cancer clinical trials, a placebo is only used if there is no other treatment for that type of cancer. This helps compare an investigational treatment to the placebo. Placebos are rarely used in cancer trials because the best available treatment, called the “standard of care”, is usually given instead.

Do I need a referral from my doctor to take part in a study?

Your doctor may not know about all the opportunities for clinical trials that are available to you. Talk to your doctor or other medical provider about clinical trial information that you find. They can help you decide if a clinical trial is right for you. If you do not find any options on this website, we recommend you visit an online public registry website like clinicaltrials.gov to see a wide variety of available clinical trials.
