Inclusion Criteria

*Female subjects, age 18 and over

*Histologically confirmed triple negative invasive breast cancer as defined as oestrogen receptor (ER) negative, progesterone receptor (PgR) negative (if available, otherwise PgR unknown), (as defined by Allred score 0- 2 or <1% of tumour cells positive for stain) and HER2 negative (immunohistochemistry 0/1+ or negative by in situ hybridization) as determined by local laboratoryHave previously untreated, non-metastatic TNBC with a tumour amenable to multiple biopsies including a T stage of at least T2. Note multifocal primary tumours are allowed providing at least one tumour meets the criteria above. All biopsies should be obtained from the same tumour.

*Have previously untreated, non-metastatic TNBC with a tumour amenable to multiple biopsies including a T stage of at least T2 T2T1c
Note multifocal primary tumours are allowed providing at least one tumour meets the criteria above. All biopsies should be obtained from the same tumour.

*ECOG performance status 0/1

Exclusion Criteria

*Prior systemic anti-cancer treatment (immune therapy, targeted therapy, vaccine therapy, or investigational treatment) for triple negative breast cancer.

*Malignancy within the last 5 years except: adequately treated non-melanoma skin cancer; curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS); stage 1, grade I endometrial carcinoma or other solid tumours that have been treated with curative intent with no evidence of disease for = 5 years.

Contraindications to aspirin dosing including hypersensitivity to aspirin (eg known aspirin sensitive asthma; history of peptic ulcer disease, gastric bleeding or cerebrovascular haemorrhages; haemorrhagic diathesis.

*Evidence of distant metastases apparent prior to randomisation. Patients who are diagnosed with distant metastases during the course of the study can complete study procedures if willing to do so.

*Subjects with active, known or suspected autoimmune disease. Subjects with type 1 diabetes mellitus, hypothyroidism only requiring hormone replacement, skin or rheumatological disorders (such as vitiligo, psoriasis, rheumatoid arthritis or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger will be permitted to enrol. Autoimmune conditions such as ulcerative colitis that have been definitively treated (e.g. with total colectomy) will be permitted to enrol but should be discussed with the CI.

*Subjects with a condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement steroid doses > 10 mg daily prednisone equivalent are permitted in the absence of active autoimmune disease.

*16.Current or previous regular use of aspirin (at any dose) or current use of another NSAID for any indication (see section 7.11 (II) prohibited medications for list of medications not permitted in the trial). Regular aspirin use is defined as taking aspirin more than twice in any given week for more than 4 consecutive weeks. Current NSAID use is defined as taking any NSAID for more than a week in the preceding month. If investigators feel that this definition may unfairly exclude a participant, this can be discussed with the CI/MCTU and a case by case decision will be made.

Primary Outcome Measures
NameTimeMethod
Primary end point(s): Mean combined gene expression of COX-2 tumour-promoting genes (ILA, IL1B, IL6, IL8, CXCL1, CXCL2, VEGFA, CFSF3 and CCL2),in samples taken post treatment ;Timepoint(s) of evaluation of this end point: Derived from samples taken at Visit 4 and/or Visit 5 ;<br> Secondary Objective: 1.To determine if Aspirin 300mg given three times daily for 18 days (+3days) enhances the efficacy of single dose Avelumab 10mg/kg by increasing cancer cell infiltration<br><br> ;Main Objective: To examine whether aspirin, given in combination with avelumab, reduces tumour promoting inflammation and thereby shifts the profile towards an anti-cancer pathway when compared to avelumab alone in patients with newly diagnosed TNBC
