Our Commitment to
Clinical Research for
Breast Cancer

For over 30 years, Gilead has developed medicines for life-threatening diseases like breast cancer. Your participation in a clinical trial is a personal, yet crucial, decision. We hope that you find the information on this page educational and informative. Thank you for considering a Gilead trial!


What are we studying?

HR+/HER2- Breast Cancer

  • Breast cancer cells have receptors that can be activated by hormones such as estrogen and progesterone hormones and or proteins such as the human epidermal growth factor
  • Cancer growth is fueled by hormones or proteins
  • Treatment is determined by receptor type and can include chemotherapy, hormone therapy surgery or radiation
  • ~69% of all breast cancers are hormone receptor positive/human epidermal growth factor receptor 2 negative

Triple Negative Breast Cancer (TNBC)

  • Triple negative breast cancer diagnosis occurs when cancer cells test negative for estrogen, progesterone and human epidermal growth factor receptor
  • ~15% of all breast cancer is triple negative breast cancer
  • TNBC is an aggressive form of breast cancer and disproportionately affects Black women


Patient Steering Council Advisors for TNBC

All trials have different timelines due to various factors, such as the trial phase, study design, treatment duration or health condition being studied. During the consent process before enrolling, the research team will explain the specifics about the trial.
Due to the many differences in insurance plans across the country, coverage in clinical trials can vary. You will learn more about your options during pre-screening.
If you don’t qualify due to not meeting the trial criteria, you should check with your healthcare provider to seek other options.
If you are living with a medical condition, joining a clinical trial may give you access to a new potential treatment before it is publicly available. Just as importantly, it can help researchers understand how this potential treatment affects the body and increase their knowledge about the disease and how to treat it. Participation can also play a vital role in helping others who have a similar condition, both now and in the future. Healthy volunteers in trials contribute to this medical progress as well by helping understand the effect of the potential treatment and any safety concerns.
As with all medical records, participant privacy and confidentiality in trials are protected by law. Once consent is signed, you will be given a trial code. Your trial records will not include your name or personal identity but will identify you with a trial code. This code can only be tracked back to you via a code key which is held by the responsible physician. Your name or personal identity will never be disclosed.
Yes, participants are volunteers and may withdraw from a clinical trial at any time.
A placebo is an inactive version of an intervention that is not intended to provide any medical benefit. It is designed to look the same as the active intervention, so the participant and research team do not know it is a placebo. The placebo is used by comparison to confirm any effects of the intervention being studied, if no approved intervention is available.
"Standard of care" is an intervention already approved for a specific health condition that is available publicly. Interventions in a clinical trial are still being tested to ensure safety and effectiveness.
Some clinical trials are designed to be "double blind" so both participants and researchers are unaware of which treatment group participants are assigned to. This prevents bias from affecting clinical trial data.
Your informed consent is required before being enrolled in a trial. This means you have been provided all relevant information about the study design, how you will participate, your right to withdraw at any time, study alternatives, your personal data protection and the associated risks and benefits. Informed consent is designed to protect patient safety and privacy.
Under FDA regulations, an Institutional Review Board (IRB) is a group that has been formally designated to review and monitor research at a hospital or institution involving human participants. In accordance with FDA regulations, an IRB has the authority to approve, require modifications in, or disapprove research.
Participants are always welcome to visit their usual healthcare providers during a trial. Sometimes, it is important for healthcare providers to collaborate with the research team to ensure success.
After your participation ends, the study may continue for months or years. Once final results from all participants are compiled and analyzed, they are often published publicly. Clinical study report (CSR) synopses and plain language summaries (PLSs) may be made available for certain studies. Check with your clinical trial site or send an email to [email protected] to learn more.
There are a wide variety of professionals involved with any clinical trial, all of whom are vital to ensuring safety and success. The principal investigator, or PI, leads the trial and directs the team of doctors, nurses and other healthcare workers. The clinical trial coordinator manages day-to-day activities and is the main contact for participants. Many clinical trials also have an independent Data and Safety Monitoring Board (DSMB) who periodically reviews data to ensure participant safety, and sometimes effectiveness.
