Aspirin’s synergistic role in cancer immunotherapy

Follow this link to download a pdf copy of the press release
  • Aspirin use appears to improve survival post diagnosis in colorectal cancers  with certain genetic mutations 
  • Immune check point inhibitors against the PDCD1 (programmed cell death 1, PD-1) to CD274 (PDCD1 ligand, PD-1) axis have shown exciting clinical benefits in the treatment of refractory cancer.
  • Aspirin appears to have a synergistic effect with new immune check point blockade therapies.

The U.S. Food and Drug Administration (FDA) has approved the anti PDCD1 (PD-1) antibody pembrolizumab for the treatment of solid tumours that have high-level microsatellite instability (MSI) or mismatch repair deficiency. This has been seen as an exciting development in cancer therapy as it is the first anticancer agent license based on a tumour biomarker rather than the actual primary cancer site.

High- level MSI is often present in colorectal cancer which may be why immune check point blockade has helped to improve survival in this cancer type. Unfortunately not all MSI-high colorectal cancers respond to immunotherapy. There are many complexities to individual colorectal cancers which are influenced by lifestyle factors, the microbiome and host cells which are thought to result in unique genetic and epigenetic aberrations and a distinct microenvironment. Predictive factors for immune response are therefore required.

Aspirin may reduce colorectal cancer mortality by inhibition of PTGS2 and prostaglandin E2 (PGE2) synthesis. In addition aspirin appears to have immune enhancing effects on the adaptive and innate immune response

These effects seen with aspirin appear to be influenced by the genetic makeup of the cancer. Colorectal cancer with lower-level CD274 (PD-L1) expression appear to benefit from better post diagnosis aspirin use than those with higher-level CD274 expression.

Activation of the CD274-PDCD1 immune checkpoint pathway may result in resistance to aspirin therapy in colorectal cancer treatment. This may be overcome with the use of immune checkpoint blockade therapies. Immune check point therapy and aspirin may work in a synergistic manner to control the progression of colorectal cancer.

Recently published science of interest about aspirin: aspirin mechanism In an Opinion article in press at Nature Reviews Cancer, we review the weight of the evidence supporting aspirin’s chemo preventive potential and highlight advances in our understanding of aspirin’s mechanisms of action. We challenge the notion that aspirin prevents cancer through a single, dominant pathway and propose an integrative multi-pathway model for its mode of action. We highlight how these pathways can be leveraged to develop mechanistic biomarkers for personalised risk stratification. Such biomarkers may then be translated clinically in a precision medicine approach critical to the future of aspirin chemoprevention.

Current clinical trials of aspirin in Italy include ACCEPT-D (Aspirin and Simvastatin Combination for Cardiovascular Events Prevention Trial in Diabetes), a primary prevention trial coordinated by Dr. Nicolucci at the Mario Negri Institute in Milan, and ASAMET, a randomized, 2x2 biomarker prevention trial of low-dose aspirin and metformin in colon cancer patients coordinated by Dr. De Censi at the E.O. Ospedali Galliera in Genova. Moreover, investigators in Rome, Chieti, Verona, Siena and Bari, coordinated by Prof. Paola Patrignani, are collaborating in investigating the role of platelet activation in intestinal tumorigenesis. They will test the hypothesis that inhibition of platelet activation may explain the efficacy of low-dose aspirin as a chemopreventive agent.
