(GRASSROOT)
What this study is about
The goal of this clinical research study is to learn about the barriers in the real world to accessing treatments for ATC. And to learn about how patients with ATC tolerate and respond to the commercially available medications for treatment of this disease, outside of a clinical study.

Primary outcome measures
Overall Survival
Time frame: Through study completion; an average of 1 year.
Prospective real-world, large-scale, comprehensive data on these patients who are unable to access traditional clinical trials but are treated with MDA regimens, assigned by stage and BRAF-status.
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 adult patients aged 18 years or older (with the exception of certain external participant countries where the legal adult age may be different; for example in Singapore, adult majors are defined by age 21 and older) with anaplastic thyroid cancer or poorly differentiated thyroid cancer as their clinical and/ or histological diagnosis will be included.
Exclusion criteria
- Patients who do not have anaplastic thyroid cancer or poorly differentiated thyroid cancer on their tumor tissue would be excluded.

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.
