Study Details

Study Description

Brief Summary

Coxsackie A21 (CVA21) virus is to be administered by IV infusion to patients with Stage 4 melanoma, prostate and breast cancer. This is a dose escalation, safety study.

Condition or Disease	Intervention/Treatment	Phase
Melanoma Breast Cancer Prostate Cancer	Drug: CVA21	Phase 1

Detailed Description

This is a phase I, multiple dose, dose escalation, open label, cohort study of three intravenous doses of Coxsackie virus A21 in patients with stage IV solid tumours. Prospective patients will attend the study centre for initial screening within 28 days prior to commencement of treatment. They will have the nature of the study and its procedures and risks fully explained. Patients must then sign an informed consent form giving permission for tumour testing before initial screening can be commenced.

Patients whose tumours test positive for ICAM-1 with or without DAF will attend the study centre for a further screening visit within 14 days prior to commencement of treatment. They will sign a full study informed consent form before any further screening procedures are carried out.

Patients who satisfy all inclusion and none of the exclusion criteria will commence the treatment stage, which consists of one or more doses of CVA21 administered by intravenous infusion as per the dosage escalation chart. The first 4 cohorts will be treated as in-patients. The follow up period will consist of 12 weeks, during which time patients will attend the trial centre for up to13 follow up visits to collect safety and efficacy data.

Outcome Measures

Primary Outcome Measures

The primary objective of the study is to determine the safety and tolerability of CVA21 given by intravenous infusion in multiple escalating doses. [Days 1, 2, 5, 6, 7, 8, 12, 16, 20, 28, 42, 56, 84]

Secondary Outcome Measures

To obtain preliminary efficacy data, determine the time course of viraemia and its elimination post-administration of CVA21 [Days 1, 2, 5, 6, 7, 8, 12, 16, 20, 28, 42, 56, 84]
To characterise the time course of the anti-CVA21 antibody response [Days 1, 2, 5, 6, 7, 8, 12, 16, 20, 28, 42, 56, 84]

Male or female aged 18 years or older.
Stage IV solid tumour disease with the primary tumour being any one of the following types - breast, prostate or melanoma.
ICAM-1 with or without DAF-expressing tumour. Patients without archival material for testing must agree to a new tumour biopsy.

Bilirubin < 20µmol/L, AST < 2.5 times the upper limit of normal
Calculated creatinine clearance > 30 mL/minute

Adequate immunologic function, defined as:

Serum IgG > 5g/L
T cell subsets within normal limits

Fertile males and females must agree to the use of an adequate form of contraception. Hormonal contraceptives should be supplemented with an additional barrier method. Negative pregnancy test is required in female patients of child-bearing potential.

Exclusion Criteria:

Presence or history of Central Nervous System (CNS) malignancy.
Patients must not have received chemotherapy within 4 weeks prior to date of consent.
Performance status > 1 on the Eastern Cooperative Oncology Group (ECOG) scale.
Life expectancy < 6 months.
Pregnancy or breastfeeding.
Primary or secondary immunodeficiency, including immunosuppressive disease, and immunosuppressive doses of corticosteroids (e.g. prednisolone > 7.5mg per day) or other immunosuppressive medications including cyclosporine, azathioprine, interferons, within the past 4 weeks.
Positive serology for HIV, hepatitis B or hepatitis C.
Splenectomy.
Presence of uncontrolled infection.

Participation in another study requiring administration of an investigational drug or biological agent within the last 4 weeks
Known allergy to treatment medication or its excipients
Any other medical or psychological condition that would preclude participation in the study or compromise ability to give informed consent.
