A Phase I Trial of AZD3965 in Patients With Advanced Cancer

• Status: Completed
• Trial end date: 2020-11-17
• Target enrollment: 0
• Participant gender: All

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 were treated at increasing doses to find the highest safe dose and best dose to give to patients in Part 2 of the study. 43 patients with advanced solid tumours were treated in Part 1.

In Part 2, the dose found to be safe in Part 1 is given to patients with diffuse large B cell lymphoma and Burkitt's Lymphoma. 15 - 20 patients will be treated in Part 2.

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 will continue until a patient's cancer starts growing but can continue for up to a maximum of 12 months if the cancer is responding to the drug. 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.

Criteria

Inclusion Criteria:

1. Part 1:

• Histologically or cytologically proven advanced solid tumour or lymphoma, refractory to conventional treatment or for which no conventional therapy exists.

• Available archived tumour samples.

Part 2:

• Histologically proven diffuse large B-cell Lymphoma (DLBCL) or Burkitt Lymphoma (BL), which is relapsed or refractory to conventional treatment or for which no conventional therapy exists or has been refused by the patient.

2. Life expectancy of at least 12 weeks

3. World Health Organization (WHO) performance status of 0 or 1 (Appendix 1)

4. Haematological and biochemical indices within the ranges shown below. These measurements must be performed within one week (Day -14 to Day -7) before the patient receives their first dose of AZD3965.

Laboratory Test Value required

Haemoglobin (Hb) ≥ 9.0 g/dL (90 g/L) or ≥10.0 g/dL (100 g/L) if transfusion within last 4 weeks

Absolute neutrophil count (ANC) Part 1: ≥ 1.5 x 10^9/L Part 2: ≥ 1.0 x 10^9/L

Platelet count Part 1: ≥ 100 x 10^9/L Part 2: ≥ 50 x 10^9/L

Serum bilirubin ≤ 1.5 x upper limit of normal (ULN)

Alanine aminotransferase (ALT), aspartate aminotransferase(AST) and alkaline phosphatase (ALP) ≤ 2.5 x ULN or ≤ 5 x ULN in presence of liver metastases

Alkaline phosphatase (ALP) ALP ≤ 5 x ULN in presence of bone metastases

Glomerular filtration rate (GFR)

Either:

Calculated creatinine clearance

Or:

Isotope clearance measurement (uncorrected) ≥ 50 mL/min

Prothrombin time <1.5 x ULN

Glucose (fasting) Part 1: < 7.8 mmol/L Part 2: < 6.1 mmol/L

5. Left ventricular ejection fraction (LVEF)>50%

6. 18 years or over

7. Written (signed and dated) informed consent and be capable of co- operating with treatment and follow-up

Exclusion Criteria:

1. Radiotherapy (except for palliative reasons), endocrine therapy, immunotherapy or chemotherapy during the previous four weeks (six weeks for nitrosoureas, Mitomycin-C and 4 weeks for investigational medicinal products) before treatment.

2. Ongoing toxic manifestations of previous treatments. Exceptions to this are alopecia or certain Grade 1 toxicities, which in the opinion of the Investigator and the CDD should not exclude the patient.

3. Known brain or leptomeningeal metastases.

4. Patients with known retinal disease or macular degeneration affecting visual acuity as assessed by ophthalmologic tests.

5. Female patients who are able to become pregnant (or are already pregnant or lactating). However, those patients who have a negative serum or urine pregnancy test before enrolment and agree to use two forms of contraception (one highly effective form plus a barrier method) [oral, injected or implanted hormonal contraception and condom; intra-uterine device and condom; diaphragm with spermicidal gel and condom] or agree to sexual abstinence, effective from the first administration of AZD3965, throughout the trial and for six months afterwards are considered eligible.

6. Male patients with partners of child-bearing potential (unless they agree to take measures not to father children by using a barrier method of contraception [condom plus spermicide] or to sexual abstinence effective from the first administration of AZD3965, throughout the trial and for six months afterwards. Men with partners of child-bearing potential must also be willing to ensure that their partner uses an effective method of contraception for the same duration for example, hormonal contraception, intrauterine device, diaphragm with spermicidal gel or sexual abstinence). Men with pregnant or lactating partners must be advised to use barrier method contraception (for example, condom plus spermicidal gel) to prevent exposure of the foetus or neonate.

7. Any major surgery in the preceding eight weeks prior to the start of treatment or major thoracic or abdominal surgery from which the patient has not yet recovered.

8. Patients who are unable to swallow oral medication.

9. Alterations to corticosteroid dose within 2 weeks prior to first dose of AZD3965.

17. Is a participant, or plans to participate in another interventional clinical trial, whilst taking part in this Phase I study of AZD3965. Participation in an observational or interventional clinical trial that does not involve administration of an IMP would be acceptable.
