About this study

Official title: A Phase 1, Pharmacokinetically-Guided, Dose Escalation Study to Assess the Safety and Tolerability of Dexanabinol in Patients With Advanced Solid Tumours

This study is a trial of Dexanabinol in patients with advanced solid tumours. The purposes of this protocol are to study different doses of the study drug to determine the maximum safe dose and to further understand the safety of the study drug; to understand what the body does to the study drug; to understand what the study drug does to the body and to measure any reduction in size of patients' cancer tumour(s).

Dexanabinol is a synthetic cannabinoid derivative with reduced psychotropic potential which was initially investigated as a neuroprotective agent. Because of its method of action however it is thought that it may have the effect of destroying cancer cells by reducing the level of control on networks that prevent cancer cells dying.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients Experiencing Dose Limiting Toxicity (DLT)

    Patients will be sequentially assigned to increasing doses of Dexanabinol, to establish the maximum tolerated dose (MTD) (highest dose it is safe to give patients) or alternatively the maximum administered dose (MAD).

    3 patients will be enrolled to a cohort to assess each dose level. Dose escalation to a cohort of 3 new patients will occur when all patients in the previous cohort have completed the first cycle i.e. the first 3 doses followed by observation through to Day 22, and no DLT has occurred. Upon occurrence of the first DLT within a cohort, an additional 3 patients were to be added to that cohort. For a six patient cohort, all 6 patients were to have completed their first dexanabinol treatment cycle with no more than 1 DLT before dose escalation to the next cohort. If 2 or more DLTs occur in a cohort, the next lower dose level will be declared the MTD.

    DLTs will be graded for severity based on the National Cancer Institute (NCI) Common Terminology Criteria version 4.03.

    Measured: Each patient will be followed for 22 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dexanabinol and Cremophor in people with Solid Tumour, run by e-Therapeutics PLC at 3 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients Experiencing Dose Limiting Toxicity (DLT) (time frame: Each patient will be followed for 22 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Feb 2017.
