We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
An inter-patient dose escalation of oral albendazole according to the following schema:

-1. 400mg daily, day 1 - 7 every 28 days
1. 400mg twice daily, day 1 - 7 every 28 days
2. 400mg twice daily, day 1 - 14 every 28 days
3. 400mg 3 times per day, day 1 - 14 every 28 days
4. 800mg twice daily, day 1 - 14 every 28 days
5. 800mg twice daily, day 1 - 14 every 21 days
6. 1200mg morning 800mg afternoon, day 1 - 14 every 21 days
7. 1200mg twice daily, day 1 - 14 every 21 days

Dose will be increased if no dose limiting toxicity occurs. If one occurs, the cohort will be will be expanded to 6. If it recurs the dose limiting toxicity has been identified and no further dose increase will occur.
Intervention code [1] 896 0
Treatment: Drugs
Comparator / control treatment
No comparator.
Control group

Primary outcome [1] 1496 0
To determine the maximum tolerated dose. No further dose increase will occur once the maximum tolerated dose is determined.
Timepoint [1] 1496 0
The maximum tolerated dose will be defined as being one dose level below that at which a dose limiting toxicity appeared in 33% of a single cohort.
Secondary outcome [1] 2692 0
1. To determine pharmacokinetics and safety profile.
Timepoint [1] 2692 0
Pharmacokinetics are measured during cycle 1. Safety is monitored through weekly visits to clinic where adverse events are identified.
Secondary outcome [2] 2693 0
2. To determine preliminary efficacy through weekly measurement of relevant tumour markers.
Timepoint [2] 2693 0
