GPT and neoplasm: While p40 mAb treatment increased the level of serum LDH in PDX mice (Figure 10A) due to the death of TNBC tumor, the level of serum ALT was markedly inhibited in p40 mAb-treated PDX mice (Figure 10B), indicating that p40 mAb immunotherapy is not toxic in TNBC mice and that p40 mAb treatment reduces liver toxicity in TNBC mice.
