| Scientific title | NEO21-RS: A phase II randomised study of the cyclin-dependent kinase 4/6 inhibitor palbociclib in combination with oestrogen suppression therapy versus oestrogen suppression therapy alone as neoadjuvant therapy in ER-positive intermediate recurrence score primary breast cancer |
| Study acronym | NEO21-RS |
| Study hypothesis | The purpose of this study is to look at different breast cancer treatments given to shrink the tumour before having surgery to remove it. Treatment given before surgery is called neoadjuvant therapy and this can be either hormone therapy or chemotherapy. A test called the Oncotype DX Breast Recurrence Score®, when used after breast surgery can help decide whether chemotherapy is needed to treat the tumour or if hormone therapy alone is the right treatment. Breast cancers with a low recurrence score (RS) are treated with hormone therapy, while for those with a high RS chemotherapy is recommended followed by hormone therapy. In breast cancers that have an intermediate RS it is not known what is the best treatment and if chemotherapy is needed to treat these cancers. Currently, the Oncotype DX® test is not available to patients who need treatment before surgery (neoadjuvant treatment). This study will give patients needing treatment before surgery access to this test. Patients with a low RS will receive hormone therapy, while those with a high RS will be treated with chemotherapy. If the breast cancer has an intermediate RS these will be randomised to compare hormone treatment alone against hormone treatment plus a new drug called Palbociclib. All patients entered will be followed up and how effective the treatment received at shrinking the breast cancer recorded. There are 2 components to this study: 1. An observational study of the outcomes for patients whose tumours have a low and high RS 2. A randomised trial to compare two different treatments for patients whose tumours have an intermediate RS breast cancer. Half will receive hormone therapy on its own and the other half will have hormone therapy plus a new drug called palbociclib. |

| Intervention | This is a multi-centre, phase II randomised, open-label study to assess the efficacy and safety of palbociclib with oestrogen suppression therapy in patients with ER-positive early breast cancer who have an intermediate recurrence score as determined by the Oncotype DX assay. There are two studies: 1. Multicentre, two-arm parallel group, open-label, neoadjuvant RCT 2. Observational cohort study Patients considered eligible for study participation will have the following screening assessments carried out within 21 days of randomisation: 1. Provision of study information (PIS and ICF) 2. Signing of Informed Consent Form 3. Assessment of eligibility criteria 4. Patient Registration to trial 5. Review of medical history and past drug history 6. Breast biopsy (up to 28 days prior to registration/randomisation) 7. 21-gene recurrence score (Oncotype Dx, Genomic Health) 8. Haematology and clinical biochemistry – 4 tubes (including FBC, LFT, clotting, glucose, FSH and E2) 9. Collection of Formalin Fixed Paraffin Embedded tissue 10. Pregnancy test (for premenopausal women only) 11. Vital signs (including BP, pulse, height and weight) Patients who satisfy the minimum eligibility requirements as follows can be enrolled on the study: 1. Received PIS 2. Written informed consent given 3. Trial registration forms signed by PI/co-investigator confirming tumour ≥ 20mm and neoadjuvant therapy required 4. 21-gene recurrence score request raised (pathology to prepare tissue specimen and send to Genomic Health, PI to forward RS request to LCTU for submission to Genomic Health) Completion of the remaining screening assessments can be undertaken whilst awaiting 21-gene RS results. Assessments carried out as part of routine care can be used for screening only if within the specified windows. On receipt of the RS score (within 10-14 days) to LCTU the result will be communicated to site within 24 hours(working day). Notification of Low and High RS results will be forwarded to the clinical team at site, detailing the RS group and value and advising the appropriate standard care pathway of endocrine therapy or chemotherapy. On receipt of an intermediate RS result to LCTU, the patient's eligibility will be confirmed and the patient randomised to the therapeutic or control arm and sites notified of the RS group (only) and the allocated treatment arm. Intermediate RS values will not be communicated until after surgery so that the clinician remains blinded; this is to avoid clinicians influencing treatment decisions as a result of borderline RS group values. Patients in the low and high RS groups will be required to attend hospital visits for the following assessments: Baseline - physical examination, vital signs, breast examination, breast ultrasound, ECOG performance status, haematology and biochemistry blood tests, translational blood sample, dispensing/administration of drug. Tissue prepared for sending for Ki67 testing. 4-weekly visits x5 (at week 4, 8, 12, 16 and 20) - breast examination, breast ultrasound (at week 12 only), concomitant medications check, ECOG performance status and drug dispensed/administered. End of treatment visit (24 weeks) - breast examination, breast ultrasound, translational blood sample, concomitant medications check, ECOG performance status. Tissue prepared for sending for Ki67 testing. Surgery Visit - pre-planned breast surgery and core biopsy (as standard of care) and collection of Formalin Fixed Paraffin Embedded Tissue. 4-weeks post surgery visit - collection of data on final treatment delivered. Patients in the intermediate RS group will be required to attend hospital visits for the following assessments: Baseline - physical examination, vital signs, breast examination, breast ultrasound, ECOG performance status, haematology and biochemistry blood tests, translational blood samples, concomitant medication check, dispensing/administration of drug, drug diary review. Tissue prepared for sending for Ki67 testing. 2 weeks visit - breast core biopsy, translational blood samples. Tissue prepared for sending for Ki67 testing. Patients receiving palbociclib will also have FBC blood sample taken for standard monitoring of toxicities. 4-weekly visits x5 (at week 4, 8, 12, 16 and 20) - physical examination, breast examination, breast ultrasound (week 12 only), haematology and biochemistry blood sample, translational blood sample, ECOG performance status, concomitant medications check, drug diary review, drug dispensing/administration, adverse event recording. 6 weeks visit (for patients receiving palbociclib only) - FBC blood sample taken for standard monitoring of toxicities. End of treatment visit (24 weeks) - physical examination, breast examination, breast ultrasound, breast core biopsy, haematology and biochemistry blood samples, translational blood samples, ECOG performance status, concomitant medication check, drug diary review, adverse event recording. Tissue prepared for sending for Ki67 testing. Surgery visit - pre-planned breast surgery (standard of care) and collection of Formalin Fixed Paraffin Embedded Tissue 4-weeks post surgery visit - collection of data on final treatment and adverse event recording. |
