Study summary

Setidegrasib (ASP3082) is being developed for certain cancers. In this study, the researchers want to understand how it is processed by the body in healthy male volunteers.

To do this, [14C] which is a certain chemical (called a tracer, or radionuclide) has been added to setidegrasib. [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 setidegrasib through the body. [14C]setidegrasib will be given as 1 single injection slowly through a vein (infusion).

The men will stay overnight in the clinic for at least 2 weeks. They will give regular blood, urine and stool samples during their stay and will be closely monitored. The men will return to the clinic about 1 week later for a final safety check.

    • Participant has previously undergone a cholecystectomy.
    • Participant has/had febrile illness or symptomatic, viral, bacterial (including upper respiratory infection) or fungal (noncutaneous) infection within 28 days prior to day -1.

    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.
