First, a single dose of 40 mg/kg of irinotecan (∼0.8 mg) administered in this study carried about 30-fold more SN-38 equivalents than IMMU-132 administered at a single 20 mg/kg dose (1.0 mg IMMU-132 containing 16 μg SN-38), yet by AUC comparisons, IMMU-132 delivered from 20-fold to as much as 136-fold more SN-38 into the tumor than irinotecan.

Thus, IMMU-132 retains SN-38 in its fully active form as it circulates in the serum. First, SN-38 bound to the antibody is in an inactive state, and therefore the intact conjugate in the serum would not pose a toxicity concern. In a text message to Malaysiakini late last night, Umno president and BN chairperson Ahmad Zahid Hamidi said the chief minister should be from Umno. However, the combined AUC for SN-38 and SN-38G in the IMMU-132–treated animals was still 9-fold lower than the combined AUC in the irinotecan-treated animals. Similar results are being found in patient samples (34–37), where (i) the IgG component clears more slowly than the conjugate, (ii) >95% of the total SN-38 in the serum is bound to the IgG, (iii) the amount of free SN-38G in the serum is only a fraction of the free SN-38, and (iv) there is no evidence of glucuronidation of SN-38 bound to IgG. Irinotecan-treated animals also had high levels of irinotecan and SN-38 in the large intestine, with SN-38 levels being nearly 20-fold higher at 6 hours than in animals given IMMU-132.

Levels of SN-38 were found in the tumor of animals given IMMU-132, and as the topoisomerase I activity of SN-38 is enhanced in S-phase cells, maintaining an SN-38 presence for 3 days compared with 8 hours would be another advantage. Although the more recently approved ultratoxic ADCs use linkers that bind the drug stably while in serum, as premature release of those agents would increase toxicity and reduce their therapeutic window, our in vivo experience revealed the optimal therapeutic activity for an SN-38 ADC required a linker that neither held the drug stably nor released it too early (9, 10, 21). We are currently in the process of developing SN-38–resistant cell lines that should provide some insights.
