Who may be able to join

  • Women aged over 18.
  • People with breast cancer that has been confirmed as HER2-positive through laboratory testing (either a strong positive result on one test, or a moderate result confirmed by a second test).
  • People whose breast cancer has been confirmed by tissue or cell testing and has either come back in the same area or spread to other parts of the body.
  • People whose HER2-positive breast cancer got worse while receiving trastuzumab (Herceptin) as a treatment after surgery.
  • People whose HER2-positive breast cancer came back or spread after completing trastuzumab treatment following surgery.
  • People with HER2-positive breast cancer that has come back or spread and got worse after receiving at least 4 weeks of trastuzumab as a first-line (initial) treatment.
  • People with HER2-positive breast cancer that has spread and who had not previously been treated, but whose cancer got worse after receiving at least 4 weeks of trastuzumab as a first-line treatment.
  • People whose genetic testing shows a mutation (change) in a specific cell-signalling pathway called PI3K/Akt/mTOR.
  • People who are generally well enough to carry out basic daily activities (as measured by a standard medical scoring system), with a life expectancy of at least 6 months and who are able to attend follow-up appointments.
  • People who have at least one area of cancer that can be measured on scans, according to a standard set of medical measurement guidelines.
  • People whose heart and lung function is broadly normal, with the heart pumping at least 50% of its capacity on a recent test taken within 4 weeks before starting treatment.
  • People with adequate liver function, meaning their bilirubin levels are within an acceptable range (up to 1.5 times the upper normal limit, with a specific allowance for people with a known condition called Gilbert's disease).
  • People whose liver enzyme levels (AST and ALT) are within acceptable limits — up to 2.5 times the upper normal limit, or up to 5 times the upper normal limit if cancer has spread to the liver.
  • People with adequate blood counts, including sufficient white blood cells, platelets (with some flexibility at lower levels if the treating doctor considers it acceptable), and haemoglobin levels.
  • People whose blood clotting indicators (INR and aPTT) are within 1.5 times the upper normal limit, unless they are taking medications known to affect these levels.
  • People with no history of serious heart, kidney, or other major organ or hormone-related diseases.
  • Women of childbearing age who have a negative pregnancy test and are willing to use reliable contraception throughout the trial.
  • People who have read and voluntarily signed the informed consent form for this trial.

  • People who have previously received a drug called Pyrotinib during first-line treatment (prior use of a related drug called lapatinib is permitted).
  • People who are currently taking immunosuppressant or long-term steroid (corticosteroid) medications, or who have had radiotherapy covering more than 25% of their bone marrow within the past 4 weeks.

This date has passed while the registry still lists the trial as open to participants. Sponsors often update a trial's status without revising its projected end date, so it may well still be recruiting — but the record is out of date in at least one respect. Check with the study contact before relying on either.
