Month: October 2021

What makes an indication especially tough? The combination of a lack of understanding about the mechanism of disease and a lack of clarity on what endpoints would be sufficient for approval of a therapy in studies of reasonable duration. This month, two good examples in the NEJM.   A phase 2b success in NASH Non-alcoholic steatohepatitis (NASH) is a common slow-progressing disease and for most affected individuals the timescale to liver-related morbidity is at least 20 years, although some progress much faster. NASH is also a graveyard of clinical programs

The weird world of synthetic biology In biology 101, one learns about the alphabet that translates DNA/RNA code into amino acids sequences ultimately resulting in proteins. Given that there are 64 possible triplet codons and 20 amino acids, multiple codons can map to the same amino acids. But this mapping can be reassigned including incorporating new amino acids – it has been done in E. coli with the promise of generating biologics with novel properties, although applications are not yet clear. A more practical application is to create strains of
