(Arm A) Avelumab + Proto Pump Inhibitor (PPI)

Avelumab

Aspirin

Lansoprazole

A Proof of Concept Window Trial of the IMmunological Effects of AveLumab and Aspirin in Triple-Negative Breast Cancer

1. Mean combined gene expression of COX-2 tumour-promoting genes, in samples taken post treatment

Post treatment tumour infiltrating lymphocytes (TIL) assessed by IHC using standardised methodology (Salgado et al., 2015)

Mean combined gene expression of the cancer-inhibitory elements of the COX-2 inflammatory signature, in samples taken post treatment

The post treatment COX-2 inflammatory signature

Safety and tolerability assessed by grade 3-4 AEs and SAEs. In addition, grade 2 renal toxicity AEs (creatinine rise) and grade 2 gastrointestinal toxicity AEs (duodenal perforation, dyspepsia, oesophageal haemorrhage, dysphagia, oesophageal pain, oesophageal perforation, oesophagitis)

Patients will be randomly assigned to one of two arms:-
21 patients into Arm A: Avelumab + Proton Pump Inhibitor (PPI)
21 patients into Arm B: Avelumab + Aspirin + PPI

Laboratory staff and the unblinded statistician ill remain blinded to trial treatment

Colourless odourless aqueous solution for infusion at dose of 10mg/kg

Lansoprazole (Proton Pump Inhibitor)

A Proof of Concept, Window Trial of the IMmunological Effects of AveLumab and Aspirin in Triple-Negative Breast Cancer

Mean combined gene expression of COX-2 tumour-promoting genes, in samples taken post treatment

Mean combined gene expression of the elements of the denominator of the COX-2 ratio, in samples taken post treatment.

The post treatment COX-2 ratio (a ratio of mean expression of 9 tumour-promoting to 15 tumour-inhibitory genes)

Safety and tolerability assessed by grade 3-4 AEs and SAEs. In addition, grade 2 renal toxicity AEs (creatinine rise) and grade 2 gastrointestinal toxicity AEs (duodenal perforation, dyspepsia, oesophageal haemorrhage, dysphagia, oesophageal pain, oesophageal perforation, oesophagitis).
