  Purpose

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.


Condition Intervention Phase
Endometrial Cancer Drug: ONC201 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2 Study of Single Agent ONC201 in Recurrent or Metastatic Endometrial Cancer

Further study details as provided by Fox Chase Cancer Center:

Primary Outcome Measures:
  • Progression free survival (PFS) rate at 12 weeks [ Time Frame: 12 weeks ]
    PFS will be calculated from the day of starting the treatment until 12 weeks

  • Objective Response rate (ORR) as determined by Response Criteria In Solid Tumors (RECIST)1.1 criteria [ Time Frame: 1-2 years ]
    ORR will be calculated from the day of starting the treatment until disease progression


Secondary Outcome Measures:
  • Safety profile of ONC201 will be determined by adverse events according to Common terminology criteria for Adverse Events (CTCAE) 4.03 [ Time Frame: 1-2 years ]
    Safety profile of ONC201 will be determined by type, frequency, severity and timing and relationship of Adverse Events and lab abnormalities to ONC201

  • Duration of response [ Time Frame: 1-2 years ]
    Duration or response will be determined from the time when a partial or complete response is seen until disease progression

  • Duration of stable disease [ Time Frame: 1-2 years ]
    Duration of stable disease will be calculated from the time of first treatment until disease progression

  • Median progression free survival [ Time Frame: 1-2 years ]
    Progression free survival will be calculated from the time of the start of the treatment until disease progression


Estimated Enrollment: 36
Actual Study Start Date: June 8, 2017
Estimated Study Completion Date: October 1, 2020
Estimated Primary Completion Date: October 1, 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ONC201 treatment Arm Drug: ONC201
ONC201 will be administered at a dose of 625 mg by mouth weekly until disease progression, unacceptable toxicity, or if the patient discontinues for any other reason. Radiologic tumor assessment would be performed at baseline, Cycle 3 Day 1, Cycle 5 Day 1, and at the end of every 3 cycles beyond cycle 5. All patients including those removed from the study due to unacceptable toxicity, will undergo radiologic tumor assessment at the time of discontinuation (End of treatment).
