Yes, probably, I'm looking to see even with multiple drugs how the 98% tumor burden reduction with leronlimab with mTNBC compares.


I found this summary with Herceptin by itself, looks like from this first paper I found they got a tumor volume reduction of 67.4% with breast cancer in animal studies.

The Efficacy of Trastuzumab in Animal Models of Breast Cancer: A Systematic Review and Meta-Analysis


Quote:
Of these, 158 experiments assessed tumour volume as the outcome measure, with 11 reporting animal survival. Trastuzumab treatment was associated with a substantial reduction in tumour growth—with control tumours growing to 3.07 times the volume of treated tumours (95%CI 2.62–3.60). That is, tumour volume in treated animals was reduced by 67.4% (95%CI 61.8% - 72.2%).



I need to make sure tumor burden translates to tumor volume, which seems to on first glance from the definition below.

tumor burden
Refers to the number of cancer cells, the size of a tumor, or the amount of cancer in the body. Also called tumor load.
