Brief Summary:
The main purpose of this study is to determine the safety and feasibility of weekly intra-peritoneal administration of Cantrixil to women with persistent or recurrent ovarian cancer, Fallopian tube cancer or primary peritoneal cancer. The study also aims to determine the maximum tolerated dose of Cantrixil in these patients when administered as a monotherapy or a combination therapy.

Primary Purpose: Treatment
Official Title: Phase I Study of Intra-peritoneal Cantrixil in Patients With Persistent or Recurrent Ovarian Cancer, Fallopian Tube Cancer or Primary Peritoneal Cancer.
Study Start Date : November 2016
Estimated Primary Completion Date : October 2019
Estimated Study Completion Date : December 2019


Arm Intervention/treatment
Experimental: Part A and Part B

Part A (Dose Escalation):

Part A is a Dose Escalation study to determine the Maximum Tolerated Dose of Cantrixil as a monotherapy.

The tolerance of Cantrixil in combination with standard chemotherapy agents will also be examined.

Part B (Expansion Cohort):

An expansion cohort of an additional 12 patients will be recruited at the MTD.

Drug: Part A: Dose Escalation of Cantrixil

Cantrixil will be administered via the intraperitoneal route only. The dose of study drug that each participant will receive will depend on how far the study has progressed when the participant enrols. There are 9 potential doses of Cantrixil, they are 0.06, 0.12, 0.24 (starting dose), 0.6, 1.25, 2.5, 5, 10, or 20 mg/kg. The dose each participant receives will remain the same during the study, unless it needs to be reduced for safety reasons. The dose will not be increased.

Each participant will receive the study drug once a week during the first two cycles; each cycle is 21-days (three weeks); the MTD will be determined during Cycle 1 only. If after two cycles of monotherapy, the patient tolerates Cantrixil adequately, they may continue to receive Cantrixil once a week and will also begin combination chemotherapy for another 6 cycles. Participants will receive no more than 8 cycles of study drug.

Other Name: TRX-E-002-1 in 20% SBECD

Drug: Part B: Expansion Cohort of Cantrixil
Once the MTD has been established, an expansion cohort will be recruited at the MTD. An additional 12 patients will be recruited in this cohort on top of those recruited in Part A at the MTD. These patients will be subjected to the same intervention described in Part A with 2 cycles of monotherapy followed by up to 6 cycles of combination therapy.
Other Name: TRX-E-002-1 in 20% SBECD




Primary Outcome Measures :
  1. Determination of the Maximum Tolerated Dose (MTD) [ Time Frame: During Cycle 1 (21 days) ]
    Determination of the MTD of Cantrixil using standard safety monitoring assessments when administered as a monotherapy.

  2. Pharmacokinetic (PK) profile of Cantrixil after intra-peritoneal (IP) administration [ Time Frame: 0-24 hours after administration ]
    Description of the PK of Cantrixil when administered as a monotherapy and in combination with standard chemotherapy agent(s)


Secondary Outcome Measures :
  1. Time to Progression (TTP) [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    TTP will be measured as the time from treatment start until objective tumour disease progression as defined by RECIST version 1.1 and/or GCIG criteria, but does not include deaths.

  2. Time to Paracentesis [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    The time to paracentesis will be measured as the time from treatment initiation until the next paracentesis event for ascites.

  3. Volume of Malignant Ascites [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    The volume of abdominal fluid will be measured by estimating the volume of malignant ascites drained at each paracentesis event.

  4. Disease Response [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    Disease response will be measured using RECIST version 1.1 criteria; during Follow-up, response may be also assessed using the Gynecological Cancer Intergroup (GCIG) response criteria that incorporates CA-125 measurements

  5. CA-125 level [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    Concentration of CA-125 in peripheral blood will be assayed in local laboratories using locally validated assays at baseline and then weekly during treatment, at the End of Therapy and during Follow-up.


Other Outcome Measures:
  1. Tolerance of Increased Dose Frequency [ Time Frame: Baseline to End of Study (maximum 36 weeks) ]
    Determination of the optimum dose and administration schedule (i.e. weekly vs twice weekly administration) using standard safety monitoring assessments, PK measurements and tolerability of delivery in the study centre.

  2. Enumeration of Circulating Epithelial Tumour Cells (CETC) [ Time Frame: Baseline, End of Monotherapy (up to 6 weeks), End of Combination Therapy (up to 24 weeks) ]
    Enumeration of CETC in peripheral blood and malignant ascites (if present) will be assayed using the MAINTRAC® CETC Count method by Genostics or similar methodology.

  3. Clonogenicity of Circulating Epithelial Tumour Cells (CETC) [ Time Frame: Baseline, End of Monotherapy (up to 6 weeks), End of Combination Therapy (up to 24 weeks) ]
    Clonogenicity of CETCs in peripheral blood and malignant ascites (if present) will be measured using the MAINTRAC® Tumour Sphere Units assay by Genostics or similar methodology.

  4. Expression of Stem Cell Markers [ Time Frame: Baseline, End of Monotherapy (up to 6 weeks), End of Combination Therapy (up to 24 weeks) ]
    Expression of stem cell markers CD44 and ALDH1 in the isolated colonies will be measured using fluorescein isothiocyanate-labelled (FITC-labelled) or alternatively labelled antibodies and scanning fluorescent microscopy techniques.

Sexes Eligible for Study:   Female

Criteria

Inclusion Criteria:

  1. Patients must have recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal cancer. The original diagnosis must be verified by a histology report. All histological sub-types and all grades of disease are eligible to participate; grade, histological sub-type and breast cancer susceptibility gene (BRCA) status must be recorded at study entry.
  2. Patients must be female and at least 18 years old.
  3. Patients with malignant ascites are eligible to participate; paracentesis will be conducted before the administration of Cantrixil. Drainage of the maximum volume of ascites necessary for symptomatic relief should be performed according to local standard operating procedures before administration of Cantrixil.
  4. Patients must have completed at least two (2) or more prior therapies (including adjuvant therapy) for their ovarian, Fallopian tube or primary peritoneal cancer prior to participation in the current study; all prior therapies must be recorded at baseline. Patients that have received prior intraperitoneal therapy are eligible for this study.
  5. Patients must have platinum-resistant relapsed disease, platinum refractory disease, or have documented intolerance to platinum therapy. Patients will not be eligible based on rising CA-125 levels alone, patients must have other clinical symptoms (such as malignant ascites) or radiological tumour measurements that support disease recurrence or progression.

Patients receiving any medications or substances that are strong inhibitors or inducers of cytochrome P450 (CYP)1A2, CYP2B6 and CYP3A4 or those substances with narrow therapeutic index are not to be enrolled. These compounds are prohibited from screening until completion of end of therapy or first post-treatment follow-up visit. For a list of prohibited medications see the University of Indiana Clinical Pharmacology Department's P450 Drug Interaction Table (http://medicine.iupui.edu/clinpharm/ddis/main-table/). Note: the use of paclitaxel is allowed, but only 24 hours after Cantrixil administration.
