Single Agent ONC201 in Recurrent or Metastatic Endometrial Cancer

Status Terminated

Clinical Trial Summary

ONC201 is a small molecule which selectively targets the G protein-coupled receptor DRD2. Downstream of target engagement, ONC201 activates the integrated stress response (ISR) in tumor cell leading to inactivation of Akt and extracellular signal-regulated kinase (ERK) signaling as well as induction of the TRAIL pathway. ONC201 also inhibits dopamine receptor 2 (DRD2), resulting in anti-tumor responses in preclinical models. Single agent ONC201 has been examined in open-label Phase I studies in patients with advanced, treatment refractory solid malignancies. Due to its differential anti-proliferative and pro-apoptotic response in tumor cells, treatment was overall well tolerated, and the recommended phase II dose of ONC201 was set at 625mg every three weeks. An additional dose-escalation phase I study (NCT02609230) is further evaluating weekly versus three week dosing in patients with advanced solid tumors and multiple myeloma. Preliminary data from these phase I studies suggests a possible clinical benefit in patients with advanced, chemo-refractory endometrial cancers, with at least one mixed response noted in a patient with clear cell histology. Hypothesis: Single agent ONC201 will demonstrate clinical benefit in women with recurrent or metastatic endometrial cancers, especially in those women with alterations in the Phosphoinositide 3 kinase (PI3K)/Akt/mammalian target of Rapamycin (mTOR) pathway.
