Study summary

ASP0367 is a potential new treatment for people with Duchenne Muscular Dystrophy and Mitochondrial Myopathies. Before ASP0367 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This study is in healthy men.

The main aim of this study is to learn how ASP0367 is processed by and acts upon the bodies of healthy men. To do this, [14C] which is a certain chemical (called a tracer, or radionuclide) has been added to ASP0367. [14C] gives off radiation, but the dose is very low (about the same as the dose from an x-ray) and will leave the body within a few days. [14C] will be picked up by a scanner and will be used to follow ASP0367 through the body. [14C]ASP0367 will be a liquid.

During the study, the men who take part will stay in the clinic for 6 days and 5 nights. Some men may need to stay up to an extra 7 days in the clinic. This will happen if there is a medical reason or if they still have traces of radiation in their blood, urine or feces. On the day before they drink [14C]ASP0367, the men will be asked about their medical history, have a medical examination, and have their vital signs checked (blood pressure and pulse). They will also have an ECG to check their heart rhythm. They will give urine, stool and blood samples for laboratory tests. They will also be asked if they have had any medical problems.

The men will fast for 10 hours or more before drinking [14C]ASP0367 and for 4 hours afterwards. They will only have one drink of [14C]ASP0367. They will need to lie still for 4 hours after drinking [14C]ASP0367. They will have their vital signs checked and give urine, stool and blood samples for laboratory tests. Then, they will give urine, stool and blood samples every day until they leave the clinic. They will also be asked every day if they have had any medical problems.

The day after they drink [14C]ASP0367, the men will also have an ECG. On the last clinic day, the men will also have a physical exam, have their vital signs checked and have an ECG. The men can leave the clinic once [14C]ASP0367 has left the body and they have no medical problems.

About 10 days later, the clinic will call the men to check if there were any further medical problems.

No other visits are planned during this study.

      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.
