Corcept Therapeutics and Lilly Continue Collaboration
US-based pharmaceutical company Corcept Therapeutics has announced that Eli Lilly and Company has agreed to fund studies to test the effectiveness of Corcept’s selective GRII receptor antagonist, CORT 108297, in rat models of olanzapine induced weight gain.
Corcept has previously published the results of studies in rats that demonstrated that CORLUX, a potent GRII (cortisol) receptor antagonist, both reduced the weight gain associated with the ongoing use of olanzapine and mitigated the weight gain associated with the initiation of treatment with olanzapine.
Joseph Belanoff, CEO of Corcept Therapeutics, said: “While it is not fully understood why the group of medications known as atypical antipsychotic medications, including olanzapine (Zyprexa), risperidone (Risperdal), quetiapine (Seroquel) and clozapine (Clozaril), are associated with varying degrees of treatment emergent weight gain, hyperglycemia and diabetes mellitus, it is possible that a cortisol receptor antagonist may eventually prove to be useful in patients who need to take these medications.
“Lilly has been vigilant in examining the metabolic changes associated with olanzapine; we are very pleased to continue our work with them and are appreciative of their support.”
