A basket trial is a type of clinical study that focuses on a specific genetic mutation—in your dad’s case, the KRAS G12C mutation—rather than where the cancer started in the body.

In traditional trials, researchers study a specific "basket," such as lung cancer. In a basket trial, they look for the "threads" that link different cancers (the genetic mutation) and test a targeted therapy across those various types of tumors. Essentially, your dad’s trial is testing if a drug that works on the KRAS G12C mutation can effectively treat his lung cancer, even if that same drug is also being tested on people with, for example, colon or pancreatic cancer who share that same mutation.

To figure out if he qualifies, you can take these steps:

1. Ask for the "Inclusion and Exclusion Criteria" Every trial has a strict list of requirements. These usually include:

• Prior treatments: Whether he has already tried specific chemotherapies or immunotherapies.
• Performance status: A general measure of his physical health and ability to perform daily tasks.
• Organ function: Blood tests to ensure his liver and kidneys are functioning well enough to process the trial medication.
• Disease status: Whether the cancer has spread (metastasized) or if he has specific types of lesions the doctors need to track.

2. Use the ClinicalTrials.gov Registry Your dad’s oncologist can provide the specific "NCT number" for the trial they are considering. You can type that number into ClinicalTrials.gov to see the full list of requirements. If you don't have the number, you can search for "KRAS G12C lung cancer" to see what is currently open.

3. Speak with the Trial Coordinator Ask your dad’s oncologist for a referral to the clinical trial team. Clinical trials are managed by research nurses and coordinators who are experts at "pre-screening." They can quickly tell you if his medical records meet the basic requirements before he has to go through further testing.

Questions you may want to ask the oncologist:

• "What is the phase of this trial (Phase I, II, or III)?"
• "Is this a targeted therapy (a pill) or a combination of treatments?"
• "What are the most common side effects seen in this trial so far?"
• "Will this require extra travel or more frequent hospital visits than his current treatment?"

It is often helpful to bring a family member or friend along to these appointments to help take notes, as there is a lot of information to process. Don't hesitate to ask the oncologist to clarify anything that feels overwhelming—they are there to help you navigate this.
