Brief Summary

Neo-CheckRay is a multicenter, open-label phase II study that randomizes luminal B breast cancer subjects candidate for neo-adjuvant chemotherapy in a 1:1:1 ratio in 3 arms:

1. the combination of weekly paclitaxel followed by dose-dense doxorubicin-cyclophosphamide (ddAC) and pre-operative radiation therapy (boost dose) on the primary tumour

2. arm 1 with the addition of the anti-PD-L1 antibody durvalumab

3. arm 2 with the addition of the anti-CD73 antibody oleclumab The primary tumour will be excised 2-6 weeks after completion of ddAC. A safety run-in is planned for the 6 first subjects before starting the randomized phase II trial. Those 6 subjects will receive the treatment given in Arm 3.

Detailed Description

This trial consists of a safety run-in followed by a phase II randomised trial. The goal of the safety run-in is to assess the safety of adding SBRT to the neo-adjuvant systemic treatment. The doses of the IMPs will be identical in the safety run-in and the phase II randomised trial. Individual subject timelines are also identical in the safety run-in and the phase II randomised trial.

The safety run-in is done as a precursor to the phase II randomised part of the Neo-CheckRay trial. Six subjects will be included in the safety run-in. These subjects are not part of the phase II total recruitment.

Subjects in the safety run-in will receive the following treatments corresponding to arm 3 of the phase II randomised trial. This consists of:

• q1w paclitaxel 80 mg/m² IV for 12 administration (12 weeks) followed by q2w dose-dense doxorubicin-cyclophosphamide IV (60 mg/m² and 600 mg/m² respectively) for 4 administrations (8 weeks)
• Anti-PD-L1 antibody durvalumab 1500 mg IV q4w for 5 administration (20 weeks)
• Anti-CD73 antibody oleclumab 3000 mg IV q2w for 4 administrations (8 weeks), followed by q4w for 3 administrations (12 weeks)
• Pre-operative radiation therapy (boost dose) 3x8 Gy on the primary tumour at week 5

If all requirements are meet during the safety run-in, then the phase II part of the study will be opened. The phase II will consist of luminal B breast cancer subjects candidate for neo-adjuvant chemotherapy will be randomised in a 1:1:1 ratio between 3 arms:

1. Arm 1: the combination of weekly paclitaxel 80 mg/m² IV followed by q2w dose- dense doxorubicin-cyclophosphamide (ddAC) (60 mg/m² doxorubicin IV and 600 mg/m² cyclophosphamide IV) and pre-operative radiation therapy on the primary tumour (3x8 Gy).

2. Arm 2: drugs regimen of Arm 1 with the addition of the anti-PD-L1 antibody durvalumab IV 1500 mg q4w.

3. Arm 3: drugs regimen of Arm 2 with the addition of the anti-CD73 antibody oleclumab IV 3000 mg q2w for 4 administrations, followed by q4w for 3 administrations.

The primary tumour will be excised 2-6 weeks after completion of ddAC. The study treatments end at surgery. All treatment after surgery, such as post-operative radiotherapy and hormonal therapy, will be performed according to standard of care and local site guidelines. The patient will then be followed for the next 5 years.

Mammaprint will only be tested for luminal B breast tumours with either Proliferation Index Ki67 ≥ 15% or histology grade III tumours. (Testing to be done during screening period).

MammaPrint result status at time of termination of all other screening procedures

• MammaPrint is high risk: subject may be randomized.
• MammaPrint is low risk: subjet can not be randomized.
• MammaPrint result is not yet known:

If the MammaPrint result is not known at time of termination of all other screening procedures, the investigator is allowed to randomize the subject and start study treatment without waiting for the result of the MammaPrint in the following situations: (Ki67 > 20 % or grade III) and Age<50 years+ cN0 OR Age ≥ 50 years + cN+ • Tumour size:

• If subject is cN0: tumour size ≥ 2 cm, as determined by MRI imaging.
• If subject is cN1, cN2 or cN3: tumour size ≥ 1.5 cm, as determined by MRI imaging.

The requirement for an MRI is not applicable in the case of medical contraindications to perform MRI (e.g., obesity or claustrophobia). In this situation, tumour evaluations should be performed by ultrasound.

• Multifocal, multicentric unilateral or bilateral breast adenocarcinoma tumours are allowed provided that all biopsiable foci are ER+/HER2- according to local testing and all foci are able to receive SBRT treatment within the defined dosimetric constraints. In some cases a separate biopsy of every focus is not mandatory, but only if every of the following conditions are present:

-small focal lesion

-lesion in close proximity to the main primary cancer from which a biopsy was taken

• the investigator and the radiologist consider the lesion to be clearly related to the main primary breast cancer from which a biopsy was taken
• the lesion will be removed during the same lumpectomy than the main primary breast cancer For bilateral, multifocal or multicentric disease, the site selected for pre-treatment biopsy should correspond to the site of largest measurable disease meeting eligibility criteria. The location of tumour biopsy site (laterality, quadrant, position from the nipple and type of imaging modality to guide biopsy) should be collected.
