I end up saying a similar thing in almost all blogs, in order to get aptamers to work effectively we need to stop thinking of them as oligonucleotide antibodies.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">It is clear that monoclonal antibodies (MAbs) have represented a tremendous success story for the pharmaceutical industry. In every case that I can think of the MAb works by inducing an immune response to a targeted molecule. This is something that MAbs are intrinsically better suited to do than aptamers. We are not going to succeed with aptamers in therapeutics by trying to make them work better than antibodies at what antibodies have evolved over millennia to do well.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">There are numerous disease indications or applications where an immune response is not what is desired. This is where aptamers can and should be directed for therapeutic application. Through our work on Alzheimer\u2019s disease at our subsidiary in Paris, NeoNeuro <strong><span style=\"color: #ff9900;\">(<\/span><\/strong><\/span><strong><span style=\"color: #ff9900;\"><a style=\"color: #ff9900;\" href=\"http:\/\/www.neoneuro-aptamers.com\">www.neoneuro-aptamers.com<\/a><\/span><\/strong><span style=\"font-weight: 400;\"><strong><span style=\"color: #ff9900;\">)<\/span><\/strong> we have realized that many of those afflicted exhibit symptoms of chronic inflammation of the brain. It is possible that increasing immune response to cells containing prion like proteins may actually accelerate the spread of neural degradation. In indications like this, or for gastro-intestinal disorders involving immune responses aptamer therapies may offer a better route than Mab therapies by blocking the immune response.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">One final point in response to the question of why are there not more aptamer based therapeutics is to simply point at the number of antibody therapies that fail. Developing any therapeutic is incredibly risky, and failures abound. If the pipeline for aptamers being developed for therapeutics was anywhere near as large there would be more successes. Even with the high risk and high cost of therapeutic development there is still a niche for aptamers.
