A Phase 2 Study of Single Agent ONC201 in Recurrent or Metastatic Endometrial Cancer

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.


Inclusion Criteria:

1. Patients must have histologically confirmed metastatic or recurrent endometrial
cancer. Eligible histologies include but are not limited to endometrioid, serous,
clear cell, carcinosarcoma, adenosquamous, and mixed histologies.

2. Patients must have measurable disease, defined as at least one lesion that can be
accurately measured in at least one dimension in accordance with RECIST criteria v.
1.1

3. Must have radiographic disease progression after 1 line of systemic cytotoxic therapy
for metastatic disease or with progression within 12 months of completing adjuvant
chemotherapy

4. Available archived tissue biopsies will be provided for correlative studies

5. Age > 18 years.

6. Eastern Cooperative Oncology group (ECOG) performance status of 0, 1, or 2

7. Patients must have adequate bone marrow, hepatic and renal function as defined below:

- Leukocytes > 3,000/micro-liter (mcl)

- Absolute neutrophil count > 1,500/mcL

- Platelets > 100,000/mcL

- Total bilirubin ≤1.5 upper limit of normal (ULN)

- Aspartate aminotransferase/ Alanine aminotransferase (AST/ALT) < 2 ULN

- Creatinine ≤1.5 ULN OR

- Creatinine clearance > 60 Ml/min/1.73 m2 for patients with creatinine levels
above ULN calculated using Calvert formula

8. Prior chemotherapy, hormonal and radiation therapy administered in the adjuvant
setting will be allowed.

9. Life expectancy at least 3 months

10. Ability to understand and willingness to sign a written informed consent and HIPAA
consent document

11. Patients must be surgically sterile or be postmenopausal, or must agree to use
effective contraception during the period of the trial and for at least 90 days after
completion of treatment.

Exclusion Criteria:

1. No prior treatment with ONC201

2. Patients who have had chemotherapy or radiotherapy within 4 weeks prior to entering
the study or those who have not recovered from adverse events due to agents
administered more than 4 weeks earlier

3. The subjects who have not recovered to baseline or CTCAE ≤ Grade 1 from related
toxicity to all prior therapies will be excluded. Patients with Non-serious adverse
events such as alopecia, fatigue, weakness, loss of appetite and nausea that are
non-significant will not be excluded.

4. Any other prior malignancy from which the patient has been disease free for less than
3 years, with the exception of adequately treated and cured basal or squamous cell
skin cancer, superficial bladder cancer, carcinoma in situ of any site.

5. The subject is unable to swallow capsules

6. Patients receiving any other investigational agents

7. Patients with symptomatic brain metastases are excluded. Patients with asymptomatic
and treated central nervous system (CNS) metastases may participate in this trial. The
patient must have completed any prior treatment for CNS metastases > 28 days prior to
study entry including radiotherapy or surgery. Steroids for the treatment of brain
metastasis are not permitted, and patients must be stable off steroid treatment for 4
weeks prior to enrollment

8. Uncontrolled inter-current illness including, but not limited to ongoing or active
infection. Any of the following in the previous 6 months: myocardial infarction,
severe/unstable angina, coronary/peripheral artery bypass graft, cerebrovascular
accident, transient ischemic attack or symptomatic pulmonary embolism.

9. Active inflammatory gastrointestinal disease, chronic diarrhea (unless related to
underlying malignancy or prior related treatment) or history of abdominal fistula,
gastrointestinal perforation, peptic ulcer disease, or intra-abdominal abscess within
6 months prior to study enrollment. Gastroesophageal reflux disease under treatment
with proton pump inhibitors is allowed.

10. Known Human Immunodeficiency Virus (HIV)-positive patients on combination
antiretroviral therapy

11. Known history of Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV) infection.

12. Other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that may increase the risk associated with study participation or study
drug administration, or may interfere with the interpretation of study results, or in
the judgment of the investigator would make the patient inappropriate for entry into
the study.

13. Pregnant or breast feeding. Refer to section 4.4 for further details.
