The trial is not designed to look at efficacy. Simple read of clinical trial info shows that patient inclusion criteria, primary and secondary end points are not geared up time this.
The trial is primarily looking at the pk of ava6000, liberated dox and the leaving group. You might get a hint of efficacy especially when we consider biopsy data but nothing to hang your hat on.
The dose increases are much smaller than the 6x used in mouse that resulted in equivalent systemic exposure. Thus the P1b and subsequent P3 might be to give only slightly higher doses - (no-one can say 160 is the right dose without looking at data ) but more frequently. Aim being to have max efficacy at site of tumour (again only possible with access to data) whilst limiting systemic exposure. Higher then this is pointless, lower is sub optimal. Hence the latest DE and the point of the trial
