In vivo mouse studies of protection from chemotherapy-induced myelosuppression and of tumor protection
“The sponsor conducted numerous in vitro and in vivo pharmacology studies to investigate both intended protection from chemotherapy-induced myelosuppression as well as unintended tumor cell protection from chemotherapy-induced cytotoxicity.”

Reviewer's view of the efficacy data
Low HSPC proliferation and efficient trilaciclib-mediated arrest may contribute to myeloprotection; tumor cells stay chemosensitive
“Results were consistent with tumor cells having high rates of cell proliferation and being sensitive to cytotoxic chemotherapeutic agents, and the overall low rate of proliferation and high efficacy of trilaciclib-mediated cell cycle arrest on HSPC and blood cells may contribute to myeloprotective effects of trilaciclib (Figure 12).”
