Recurrent Ovarian Carcinoma Clinical Trial
Official title:
Phase II Study of ONC201 Plus Weekly Paclitaxel in Patients With Platinum-Resistant Refractory or Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer
This phase II trial studies the side effects of ONC201 and paclitaxel and how well they work in treating patients with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent), or that does not respond to treatment (refractory). ONC201 is the first in its class of drugs that antagonize some specific cell receptors on cancer cells, leading to their destruction. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ONC201 and paclitaxel may work better in treating patients with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer compared to paclitaxel alone.

For study drugs for which 5 half-lives is =21 days, a minimum of 10 days between termination of the study drug and administration of current study treatment is required. - Major surgical procedures =21 days of beginning study treatment, or minor surgical procedures =7 days. No waiting required following port-a-cath placement, ureteral stent placement, percutaneous nephrostomy tube placement. - No other (chemotherapy, immunotherapy, hormonal anti-cancer therapy, radiotherapy [except for palliative local radiotherapy]), biological therapy or other novel agent is to be permitted while the patient is receiving study medications - Grade >1 toxicity from prior therapy (except alopecia or anorexia or above hematologic criteria) unless controlled by medications. - Inability to swallow oral medication. Note: Patient may not have a percutaneous endoscopic gastrostomy (PEG) tube or be receiving total parenteral nutrition (TPN) on this trial. - Known malignant central nervous system disease other than neurologically stable, treated brain metastases - defined as metastasis having no evidence of progression after treatment for at least 4 weeks (including brain radiotherapy). Must be off any systemic corticosteroids for the treatment of brain metastases for at least 14 days prior to enrollment. - Patient has had prescription or non-prescription drugs or other products (i.e. grapefruit juice) known to be moderate to strong inhibitors or inducers of CYP3A4, which cannot be discontinued 1 week prior to Day 1 of dosing and withheld throughout the study until 1 weeks after the last dose of study drug. - Any known hypersensitivity or contraindication to the components of study treatment - Pregnant or lactating - Serious active infection at the time of enrollment, or another serious underlying medical condition at discretion of the enrolling physician that would impair the ability of the patient to receive study treatment. HIV or other immunodeficiency disease that is well controlled and that does not impact baseline lab values (i.e. outside of above noted parameters for inclusion) are NOT considered exclusion criteria. - Presence of other active cancers other than ovarian cancer except those that do not require active therapy (i.e. on surveillance) and known non-invasive cancers and in situ cancers (e.g. non-melanoma skin cancers). - Psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol. |

Other | NK cell evaluation | NK cell evaluation by immunohistochemistry (IHC) will be performed. Wilcoxon signed ranks test will be used to compare individuals and groups pre/post treatment. Percentage of NK cells as a component of total lymphocytes over time will be evaluated using repeated measures ANOVA. Additionally, percentage of Granzyme+ and TRAIL+ NK cells will be evaluated comparing day 0 (pre-treatment) and day 4 via paired two sided t-test analysis. | Up to 1 year | |
Other | Cytokine profile | Repeated measured ANOVA will be conducted to assess for any changes in each of these molecules/cytokines over time. If a significant association with time is identified, pairwise comparisons between various time-points will be assessed using paired t-tests with a Tukey adjustment for multiple comparisons. | Up to 1 year | |
Primary | Incidence of treatment related adverse events (AEs) (Part 1) | Graded according to National Cancer Institute (NCI) Common Terminology Criteria in Adverse Events (CTCAE) version (v)5.0. | Up to 28 days | |
Primary | Incidence of dose limiting toxicities (DLT's) (Part 1) | Graded according to NCI CTCAE v5.0. | Up to 28 days | |
Primary | Objective response rate (ORR) (Part 2) | Defined as the proportion of patients achieving a complete (CR) or partial tumor response (PR) by computed tomography (CT) evaluation according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Will be calculated as the proportion of patients achieving a complete or partial tumor response according to RECIST v1.1 criteria and its associated 1-sided 92% confidence interval (CI) will be also estimated using Pearson-Klopper's exact method. | Up to 1 year | |

Secondary | HE-4 response rate | Defined as proportion of patients achieving a 50% reduction in HE-4 levels from baseline over time, if baseline level is >= 2 x ULN within 2 weeks prior to starting treatment, respectively. Differences in these markers by response will be assessed by Fisher's exact tests, and difference in these markers over time will be assessed using McNemar's tests. | Up to 1 year | |
Secondary | Plasma concentrations of ONC201 | Examined to assess drug interactions with paclitaxel and characterize the pharmacokinetics (PK). PK parameters will be estimated using non-compartment or compartment models and summarized in mean and CIs under the assumption of log-normal distribution. | Up to 1 year | |
Secondary | Pharmacodynamic studies | As a biomarker of apoptosis, the serum cCK18 (M30 assay) and CK18 (M65 assay) will be used to quantify serum caspase-cleaved and total cytokeratin 18 levels. Prolactin levels will be assayed from the collected serum specimens. Repeated measured ANOVA will be conducted to assess for any changes in apoptosis and prolactin by time. If a significant association with time is identified, pairwise comparisons between various time-points will be assessed using paired t-tests with a Tukey adjustment for multiple comparisons. Tissue based biomarkers will be evaluated based on archival (pretreatment) and on-study biopsy tissue and compared via pre/post treatment H-score both within each individual patient and among the group of patients. Wilcoxon signed rank test will be used for pre/post comparisons. | Up to 1 year | |
Secondary | Overall survival | The distributions of additional time-to-event endpoints will be summarized using KM curves and their median and CI's will be further estimated using KM estimates. | From study treatment initiation to death, assessed up to 1 year |
