| Hazard Information | Back Directory | [Uses]
Nirogacestat dihydrobromide (PF-3084014 dihydrobromide) is a reversible, orally bioavailable, noncompetitive, and selective γ-secretase inhibitor with an IC50 of 6.2 nM. Inhibition of Notch signaling by Nirogacestat dihydrobromide while minimizing gastrointestinal toxicity presents a promising approach for research of Notch receptor-dependent cancers[1]. | [in vivo]
Nirogacestat (PF-03084014) shows robust antitumor activity in this model on 14-day twice daily dosing. Tumor growth inhibition is dose dependent, with maximal tumor growth inhibition of ~92% obtained at high dose levels (150 mg/kg). In tumor growth inhibition studies where mice receive repetitive twice daily dosing for more than a week, Nirogacestat is well tolerated at dose levels below 100 mg/kg as no significant weight loss, morbidity, or mortality is observed. When the dose is increased to 150 mg/kg, however, mice have diarrhea and show weight loss (10-15%) approximately 10 days after compound administration. The body weight of treated animals usually returns to normal if dosing holidays are given, suggesting that the toxicity of Nirogacestat is reversible[1]. | [storage]
