Who may be able to join

  • After completing all main breast cancer treatment, a bone marrow sample (tested at the University of Pennsylvania) shows small numbers of cancer-related cells still detectable.
  • A person has been diagnosed with stage II or III breast cancer that tested positive for estrogen receptors (ER+) and negative for HER2, with no signs of the cancer coming back. People with cancer in both breasts may still be eligible if both cancers fit these criteria.
  • The breast cancer tumour tested positive for estrogen receptors (ER+) and negative for HER2. Tumours that are estrogen receptor-negative but progesterone receptor-positive are not eligible.
  • All main treatments (surgery, chemotherapy, and radiation) have been completed, except for ongoing hormone (endocrine) therapy. Any side effects from previous treatment must have mostly resolved before joining.
  • A person may have previously received a type of cancer drug called a CDK4/6 inhibitor, as long as it was not Palbociclib and was stopped at least 6 months before screening.
  • A person must currently be receiving adjuvant hormone (endocrine) therapy, and must have started that therapy between 2 and 7 years before enrolling. People taking tamoxifen may need to switch to a different hormone therapy (an aromatase inhibitor) at least 21 days before starting study treatment if assigned to certain trial arms (confirm with trial site). Women who have not yet gone through menopause and are using ovarian suppression therapy are eligible.
  • People already taking bone-strengthening medications (such as bisphosphonates or RANK-ligand inhibitors) may continue them, but these medications cannot be started for the first time during the trial.
  • A person is not currently enrolled in any other clinical trial involving an experimental treatment.
  • Adults aged 18 years or older, both men and women.
  • A person has no medical reasons that would prevent them from safely taking the study medications, and no serious uncontrolled health conditions.
  • A person has adequate bone marrow, liver, and kidney function (confirm specific thresholds with trial site).
  • A person is able to speak and understand English.

Who may not be able to join

Each point below is a reason the trial team may not be able to accept someone. It is not a list of requirements to meet.

  • People who have had a previous separate invasive breast cancer diagnosis. People with a prior non-invasive breast condition called DCIS may still be eligible if it was diagnosed more than 5 years before joining. People with a history of other cancers (not breast cancer) may be eligible if they have been cancer-free for at least 5 years.
  • People who are regularly taking high doses of steroid medications (such as prednisone or similar drugs) or other immune-suppressing medications. Steroid creams or inhalers are generally acceptable.
  • People whose heart electrical activity test (ECG) shows a reading called QTc greater than 480 ms, indicating a potential heart rhythm concern.
  • People with certain serious or uncontrolled health conditions, including:
    • A chronic autoimmune disease
    • Significant uncontrolled heart rhythm problems (note: controlled atrial fibrillation is generally acceptable)
    • A heart attack, unstable angina, or certain heart procedures within the 6 months before enrolling
    • Moderate to severe heart failure (Class II or above as defined by a standard medical scale)
    • A history of lung inflammation (pneumonitis) or seriously reduced lung function, or blood oxygen levels of 88% or below while at rest
    • Uncontrolled diabetes
    • Active or uncontrolled serious infections
    • Serious liver disease such as cirrhosis or chronic hepatitis
    • People living with HIV who are currently on combination HIV treatment, due to potential interactions with the study drug Palbociclib
    • Conditions affecting the digestive system that could interfere with how the body absorbs one of the study drugs (hydroxychloroquine), such as severe nausea, vomiting, diarrhoea, or malabsorption conditions
    • Active uncontrolled bleeding conditions, or people currently taking blood-thinning (anticoagulant) medications
    • A history of eye conditions affecting the retina (the back of the eye)
  • People who are pregnant or breastfeeding, or people of reproductive age who are not using effective contraception.
