A Phase I Trial of AZD3965 in Patients With Advanced Cancer

Diffuse Large B Cell Lymphoma Clinical Trial

Official title: A Cancer Research UK Phase I Trial of AZD3965, a Monocarboxylate Transporter 1 Inhibitor (MCT1) in Patients With Advanced Cancer

Status Completed

Clinical Trial Summary

The main aims of this clinical study are to find out the maximum dose that can be given safely to patients, the potential side effects of the drug and how they can be managed and what happens to AZD3965 inside the body.

AZD3965 is a type of drug called a monocarboxylate transporter 1 inhibitor which is being used to stop the growth of cancer cells and kill cancer cells by blocking the action of one of the proteins involved in moving chemical compounds in and out of the cells of the body. This will be the first time that this type of drug has been given to patients.

The drug is a capsule and is taken daily. The study is in two parts. In Part 1 of the study, small groups of patients are treated at increasing doses to find the highest safe dose and best dose to give to patients in Part 2 of the study. It is planned that 40 patients will be entered into Part 1 of the trial.

In Part 2, the dose found to be safe in Part 1 is given to patients with diffuse large B-cell lymphoma (DLBCL) and Burkitt's lymphoma (BL). It is planned that 20 patients will be entered into Part 2 of the trial.

Patients will need to visit the hospital weekly for two months and then every fortnight. Patients will have regular blood and urine tests, scans, heart traces and eye tests amongst other clinical tests. Research blood samples will also be taken to look at what happens to the drug inside the body. Treatment is planned to be given for up to 6 months, but patients benefiting from treatment will be able to keep having it for as long as they continue to benefit. It is important to explain that this is the first study of this drug and patients will have advanced cancer so it is unlikely that patients will benefit directly from taking part but the study may help improve future treatment of cancer.

Clinical Trial Description

Part 1 follows a rolling six dose escalation schedule of AZD3965 given once daily (OD) or twice daily (BD) until the maximum tolerated dose (MTD) is defined.

The recommended Phase II dose (RP2D) is based on the safety and pharmacokinetic (PK) results from Part 1.

All patients in Part 2 are treated at this RP2D to further explore the tolerability of this dose and schedule and to explore proof of principle of MCT1 inhibition in tumour types that were shown to express MCT1 and in which AZD3965 showed some effect pre-clinically (DLBCL and BL). ;
