Francesco Maura, MD, on Genomic Determinants of Resistance in Newly Diagnosed Multiple Myeloma Treated With Targeted Immunotherapy

The study was, the purpose was to identify mechanism or resistance to a combination of drugs called quadruplets with daratumumab, carfilzomib, Revlimid and dexamethasone for newly diagnosed multiple myeloma. The study was published two years ago by Ola Landgren [inaudible 00:00:21] Oncology as a clinical trial. This study is the correlative based on the genomics, so we sequence for genome sequencing of all the available samples. The main result is that we discover several known and new genomic features associated with poor or worse outcome and failure to achieve sustainable negativity. These features tend to cocoon together. So what we identify is a complex network that require more cases to be really deciphered. But that's an important step because it highlights how the technology we use that is whole genome sequencing is probably the way to go to re-understand the DNA based mechanism of resistance for multiple myeloma. But the next steps are in expanding the sample size, working with the community with additional trials where the quadruplets combination with daratumumab plus bortezomib inhibitor plus immunomodulatory agent and corticosteroids were used for newly diagnosed multiple myeloma patients. Try to see also if the same mechanism are involved in a relapse settings because patients get also these drugs in a relapse setting where the disease transform or evolve after previous therapy. And using all this information, once we have a large number of cases, we can of course develop prediction to identify patients that can benefit and patients where they cannot benefit from these regimens. And so for the one that don't, we can identify alternative strategies.
