SRA73721 Nov 2022 23:03
Not the most recent of developments regarding SRA737 but still pertinent.
Study co-leader Professor Paul Workman, Chief Executive of The Institute of Cancer Research, London, said:
"Our new study establishes the basis for a potentially exciting new approach to treatment involving a two-pronged attack on cancer. We found that doubling up on drugs that target the systems for repairing DNA could be effective even against cancers that do not respond to single-drug treatment.
"Our findings also provide us with a way of picking out which patients are most likely to benefit from existing CHK1 inhibitors like SRA737 - a highly innovative drug discovered at the ICR and currently in clinical development.
"At the ICR, we believe that combinations of targeted drugs will be critical as we aim to overcome the major challenge of cancer evolution and drug resistance - just as they have been in other diseases such as HIV."
Study co-leader Professor Michelle Garrett, previously a Team Leader at The Institute of Cancer Research, London, and currently Professor of Cancer Therapeutics at the University of Kent, said:
"Our study shows the potential of targeting DNA replication for adding to the effect of an existing drug that blocks a system that helps respond to DNA damage.
"It's exciting too that detecting tumours with low levels of B-family DNA polymerases could be used to identify patients most likely to respond to a CHK1 inhibitor, presumably because of natural weaknesses in DNA repair within these cancers.
"The next step is to develop new drug candidates that could be used to target B-family DNA polymerases in combination with the CHK1 inhibitor SRA737, as we have shown that this could open up a potential new therapeutic approach.
Time consuming, but perhaps a big maybe Sareum would become involved in new candidate development funds permitting. A long way off but viable.
