ONC201 in Recurrent/Refractory Metastatic Breast Cancer and Advanced Endometrial Carcinoma

NCT03394027

Description:

Background: The new drug ONC201 have been shown to kill breast cancer and endometrial cancer cells in the laboratory. The exact mechanism of action is not completely clear yet, but the ONC201 destroys the mitochondria inside the cells. Blocking mitochondrial activity may kill tumor cells, which would shrink tumors. Researchers want to see if ONC201 helps shrink tumors of certain breast or endometrial cancers and if that effect is maintained. Objective: To see if ONC201 shrinks tumors with a lasting effect. Eligibility: Adults ages 18 and older who have metastatic breast cancer (hormone-positive or triple-negative) or metastatic endometrial cancers. Design: Participants will be screened with: <TAB>Medical history <TAB>Physical exam <TAB>Heart, blood, and urine tests <TAB>CT and bone scans <TAB>Review of medical report and tumor sample Participants will have a tumor biopsy before starting treatment and after 5 weeks taking the study drug. A scan or ultrasound may be used to guide the biopsy. Patients will receive local anesthetic and a needle will remove a small piece of tumor. The study will be done in 28-day cycles. Every day 1 of each cycle participants will repeat most screening tests, will be seen by the physician and receive a supply of the study drug. Participants will take the study drug by mouth once every 7 days. They will keep a diary of when they take the drug and any side effects. During cycle 1, participants will get weekly calls to discuss their health and symptoms. Images will be repeated every 2 cycles to evaluate reponse to the treatment. ...

Detailed Description

      Background:

        -  Advanced breast cancer and endometrial cancer have limited treatment options. Current
           treatments provide a modest improvement in progression free survival but no treatments
           improve survival.

        -  ONC201 is the founding member of a novel class of anticancer drugs called imipridones.
           The exact mechanism of ONC201 is unknown at this time, but preclinical data suggests
           that it causes global downregulation of mitochondrial genes leading to mitochondrial
           damage and ultimately non-apoptotic cell death.

        -  Preclinical studies have demonstrated that ONC201 selectively kills various cancer
           cells, including breast cancer cells (hormone-receptor positive cell lines, HER2+ cell
           line as well as triple negative breast cancer cell lines) and endometrial cancer cells,
           while having little effect on normal cells.

        -  An on-going phase I study of ONC201 has demonstrated clinical benefit in some solid
           tumors, including endometrial cancer.

      Objectives:

        -  Cohort 1: To determine the progression free survival (PFS) at 8 months of ONC201 in
           metastatic hormone receptor positive breast cancer (HR+BC)

        -  Cohort 2: To determine the overall response rate (ORR) of ONC201 in metastatic triple
           negative breast cancer (TNBC)

        -  Cohort 3: To determine the ORR of ONC201 in advanced endometrial cancer (EC)

      Eligibility:

      Selected Inclusion Criteria

        -  Histologically confirmed metastatic breast cancer or endometrial cancer with appropriate
           IHC testing and confirmation of HER2 non-amplification required for the breast cancer

        -  Started denosumab or bisphosphonate therapy within 28 days prior to Cycle 1 Day 1

        -  HIV, Hepatitis B, or Hepatitis C infection

      Design:

        -  This is a phase II single arm study of ONC201 divided in three cohorts, each cohort with
           different type of metastatic, advanced disease:

        -  Cohort 1: HR+ breast cancer (male and female)

        -  Cohort 2: Triple negative breast cancer (male and female)

        -  Cohort 3: Endometrial cancer (female only)

        -  All patients will receive ONC201 at the recommended phase 2 dose (RP2D) of 625mg by
           mouth every 7 days with each cycle being 28 days long. Patients will receive ONC201 as
           long as they derive clinical benefit or toxicity becomes impeditive

        -  Patients will be evaluated for toxicity every 4 weeks by CTCAE v4.0 and for response

      every two cycles (8 weeks) by RECIST 1.1.

             breaking, crushing, opening or otherwise altering the product formulation.

          -  The effects of ONC201 on the developing human fetus are unknown. For this reason and
             because imipridone agents are known to be teratogenic, female patients must either be
             of non-reproductive potential (i.e., post-menopausal by history: greater than or equal
             to 60 years old and no menses for greater than or equal to 1 year without an
             alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal

             the study and for and for at least 4 weeks after the final dose of any study-related
             medications. Male patients must use at least two forms of contraception during the
             study and for at least 4 weeks after the final dose of any study-related medications

          -  Ability of subject to understand and the willingness to sign a written informed
             consent document.

        EXCLUSION CRITERIA FOR COHORT 1: HORMONE RECEPTOR POSITIVE BREAST CANCER:

          -  Patients who have received chemotherapy in the previous 3 weeks (6 weeks for
             nitrosoureas or mitomycin); other investigational agents within 3 weeks or a PD1/PDL1
             agent within 4 weeks prior to study enrollment.

          -  Patients who have undergone radiotherapy within 4 weeks of study entry.

          -  Patients with a history of another invasive malignancy within the last 3 years.

        Patients with symptomatic brain metastases or leptomeningeal involvement. Patients with
        asymptomatic or brain metastases that have been treated with radiation at least 4 weeks
        prior to study enrollment are allowed.

             tachyarrhythmias or bradycardia, history of congestive heart failure, or myocardial

             within 28 days prior to Cycle 1 Day 1.

          -  Pregnant women are excluded from this study because ONC201 has the potential for
             teratogenic or abortifacient effects. Because there is an unknown but potential risk
             for adverse events in nursing infants secondary to treatment of the mother with
             ONC201, breastfeeding should be discontinued if the mother is treated with ONC201.
             These potential risks may also apply to other agents used in this study.

          -  HIV-positive patients on combination antiretroviral therapy are ineligible because of
             the potential for pharmacokinetic interactions with ONC201.

             10%), PR negative (PR <10%). HER2 will be considered negative per ASCO-CAP guidelines
             (HER2 test result as negative if a single test (or both tests) performed show: 1) IHC
             1+ as defined by incomplete membrane staining that is faint/barely perceptible and
             within >10% of the invasive tumor cells; 2) IHC 0 as defined by no staining observed
