ColoAd1 – An oncolytic adenovirus derived by directed evolution
Attempts at developing oncolytic viruses have been primarily based on rational design. However, this approach has been met with limited success. An alternative approach employs directed evolution as a means of producing highly selective and potent anticancer viruses. In this method, viruses are grown under conditions that enrich and maximize viral diversity and then passaged under conditions meant to mimic those encountered in the human cancer microenvironment. Using the “Directed Evolution” methodology, we have generated ColoAd1, a novel chimeric oncolytic adenovirus. In vitro, this virus demonstrated a >2 log increase in both potency and selectivity when compared to ONYX-015 on colon cancer cells. These results were further supported by in vivo and ex vivo studies. Importantly, these results have validated this methodology as a new general approach for deriving clinically-relevant, highly potent anti-cancer virotherapies. This virus is currently in clinical trials as a novel treatment for cancer.

From Camels to Worms: Novel Approaches for Drug Discovery in Parkinson’s Disease
The discovery of novel treatments for neurodegenerative diseases, such as Parkinson’s disease, represents one of the biggest scientific challenges of the 21st century. The development of new tools and models to study the mechanisms underlying neurotoxicity is therefore essential. During my talk, I will outline new strategies for drug design and innovation used during my PhD at the University of Cambridge, which include the combination of fluorescent nematode worms, camelid antibody fragment technology and chemical compounds. These novel approaches will help us to gain insights into the key pathogenic steps involved in Parkinson’s disease and potentially lead to new therapeutic strategies.
