Study type
Description of intervention(s) / exposure
Treatment: Drugs - Part A: Dose Escalation of Cantrixil
Treatment: Drugs - Part B: Expansion Cohort of Cantrixil

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.

Treatment: Drugs: 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.

Treatment: Drugs: 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.

Key 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.

6. At least 4 weeks must have passed from any previous therapy and any toxicities from
prior therapies (6 weeks for bevacizumab, nitrosoureas or mitomycin C treatment) must
have resolved to less than or equal to Common Terminology Criteria for Adverse Events
(CTCAE version 4.03) Grade 1 with the exception of alopecia, Grade 2 prior
platinum-therapy related neuropathy and Grade 2 anaemia.

7. Patients must have a performance status of Eastern Cooperative Oncology Group (ECOG) 0
to 2 and, in the Investigator's opinion, be able to complete at least a major part of
the study.

8. Patients must be willing and able to undergo insertion of a port or catheter for
intraperitoneal access; the type of port or catheter used will be recorded.

9. Patients may have measurable or non-measurable disease; disease response and

using contrast CT, MRI and CA 125 measurements.

10. Patients must have acceptable hepatic and marrow function as defined below:

- Absolute neutrophil count >1.5 x 109/L

days for platelet transfusions, respectively.

excluded. Women of childbearing potential must have a negative pregnancy test within 7
days prior to screening.
