Importantly, in vivo treatment experiments showed that one of the new immunotoxins could efficiently halt tumor growth at doses lower than 0.75 mg/kg, and it had a maximum tolerated dose (MTD) higher than 8.0 mg/kg, showing a substantially improved MTD and a broadened therapeutic window than the previously reported anti-HER2 immunotoxins.

Moreover, PTPN2 deletion in T cells expressing a chimeric antigen receptor (CAR) specific for the oncoprotein HER-2 increased the activation of the Src family kinase LCK and cytokine-induced STAT-5 signalling, thereby enhancing both CAR T-cell activation and homing to CXCL9/10-expressing tumours to eradicate HER-2<sup>+</sup> mammary tumours in vivo.

Despite this achievement, general principles from proposed systems pharmacokinetic modeling for intracellular processing of ADCs indicate potential shortcomings of T-DM1: (i) <i>C</i><sub>max</sub> limited by toxicities; (ii) slow internalization rate; (iii) resistance mechanisms due to defects in intracellular trafficking [loss of lysosomal transporter solute carrier family 46 member 3, (SLC46A3)], and increased expression of drug transporters MDR1 and MRP1; and (iv) lack of payload bystander effects limiting utility in tumors with heterogeneous HER2 expression.
