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.

Eligibility
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
progression will be measured and assessed according to RECIST version 1.1 criteria
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

- Platelets >100 x 109/L

- Total bilirubin; <2.5 times the institutional upper limit of normal (ULN)

- Haemoglobin (Hb) of >10 g/dL; patients with Hb >9g/dL will be considered for this
study if they have not received a transfusion or other bone marrow support.
Patients with Hb >10 g/dL that have received a recent transfusion will only be
eligible if there has been a wash-out period of 7 days for rhesus factor and 10
days for platelet transfusions, respectively.

- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase
[SGOT])/ alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase
[SGPT]) =2.5 x institutional ULN.

- Serum creatinine <1.5 x ULN

- Prothrombin time (PT) or international normalised ratio (INR) =1.5 x ULN and
activated partial thromboplastin time (aPTT) =1.5 x ULN if not on anticoagulation
treatments.

11. Patients must be willing and able to comply with all study requirements, including
treatment timing and/or nature of required assessments and treatment at designated
study centre.

12. Each participant must be adequately informed about the purpose of the study; potential
benefits and risks; their right to refuse participation or to withdraw consent at any
time; institutional affiliation and potential competing interests of the researcher;
and sources of study funding and have signed and dated a written informed consent
form.

Key exclusion criteria
1. Patients who have had chemotherapy, biologic therapy, immunotherapy, or radiotherapy
within 4 weeks (6 weeks for bevacizumab, nitrosoureas or mitomycin C) prior to
entering the study.

2. Patients must not have had major surgery within 4 weeks prior to screening.

3. Patients may not have received any other investigational medicinal products (IMPs) or
participated in any other interventional clinical research studies within 3 months of
the first Cantrixil administration.

4. 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.

5. Patients at high risk of bowel perforation are excluded, including but not limited to
any one or more of the following;

- Patients with a recent history (previous 12 months) of bowel obstruction prior to
study entry

- Patients with CT scans that suggest invasion of bowel by tumour

- Patients with symptoms to suggest impending bowel obstruction

- Patients with prior whole abdominal radiotherapy

- Patients with chronic inflammatory bowel diseases such as Crohn's disease or
ulcerative colitis

6. Patients may not have uncontrolled or severe systemic diseases or psychiatric
conditions, which in the treating physician's opinion makes it unsafe for the patient
to participate in the study or would hinder compliance with the protocol. Screening
for chronic conditions is not required.

7. Patients that are pregnant, lactating, or unable to adopt adequate contraception are
excluded. Women of childbearing potential must have a negative pregnancy test within 7
days prior to screening.

8. Patients with a known history of hepatitis B or C.

9. Patients known to have tested positive for human immunodeficiency virus (HIV)

10. Patients with a known hypersensitivity to or serious reaction to benzopyrans are
excluded.
