PALLET is an international, multicentre, phase II, randomised, open label collaborative study to assess the biological and clinical effects of palbociclib in women with ER+/HER2-, invasive early breast cancer, with or without letrozole, in the neoadjuvant setting.
PALLET will be run in parallel in the UK and in North America. The UK trial is managed by ICR-CTSU.
A total of 306 patients will be randomised to receive one of four treatments before their breast cancer surgery:
- Letrozole alone for 14 weeks
- Letrozole for 2 weeks followed by letrozole + palbociclib to 14 weeks
- Palbociclib for 2 weeks followed by letrozole + palbociclib to 14 weeks
- Letrozole + palbociclib for 14 weeks.
Patients will be followed up for 1 year following randomisation.
