Y, WES of sequential tumour biopsies demonstrated clear temporal genomic heterogeneity. Lastly, the PIK3CA VAF differed between pre- and post-copanlisib tumour, suggesting a feasible inhibitory impact of copanlisib around the PIK3CA-mutated clone. Overall, we determined a suggested phase 2 dose for this novel mixture of copanlisib in combination with trastuzumab and this trial is now ongoing. No dose limiting RGS19 drug toxicities emerged and no unexpected novel toxicities connected for the combination have been reported. Outcomes of serial genomic analysis are provocative and worth further exploration.Cancers 2021, 13,11 ofSupplementary Supplies: The following are available on the internet at https://www.mdpi.com/2072-669 4/13/6/1225/s1, Figure S1: (a): Schematic diagram of tissue samples collected, and analysis performed.

The percentage of serial plasma samples with detectable PIK3CA mutation and the percentage of those with 500 copies/mL of mutant alleles for these hotspot mutations H1047R, E542K and E545K are shown, as analysed by droplet digital PCR (ddPCR). Plasma samples have been collected at baseline and each two weeks though on study for all patients.
