Temsirolimus (CCI-779) inhibited the growth of xenografts derived from both cell lines with greater effects against PC-3 than DU145 tumors. Temsirolimus caused mild myelosuppression. The activity of mitoxantrone or docetaxel was limited, but CCI-779 given between courses of chemotherapy increased growth delay of PC-3 xenografts. High-dose temsirolimus inhibits mTOR signaling through an FKBP12-independent mechanism that leads to profound translational repression. This distinctive high-dose compound effect could be directly related to the antitumor activities of temsirolimus and other rapalogues in human cancer patients. The rapamycin analogue CCI-779 is an important new agent to investigate in the treatment of human brain tumors, particularly PNET/MB. The rapamycin analogue temsirolimus improved performance on four different behavioral tasks and decreased aggregate formation in a mouse model of Huntington disease.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
