Interventions
Current interventions as of 12/07/2016:
This is an open-label, non-randomised, phase I, sequential group trial which will explore the safety and tolerability of ascending doses of replication defectiv
then seen at weeks 2, 3 and 4, then monthly for 12 months or until PSA progression.

Eligibility

Male
Inclusion criteria
Inclusion criteria: 1. Patients who present with biopsy proven local recurrence of prostate cancer following radical radiotherapy and a rising PSA while on androgen suppression with LHRH agonist therapy or after bilateral orchidectomy. A rising PSA is defined as 3 consecutive increases (measured by the same laboratory) over a minimum period of 6 weeks, with timepoints separated by at least 15 days. If the patient is on LHRH agonist therapy, this therapy should be continued. 2. Life expectancy greater than 3 months 3. Aged at least 18 years 4. Written informed consent 5. WHO performance status of 0-1 (Appendix 2) 6. PSA value = 4 and = 25 ng/ml at study entry 7. Adequate hepatic function (i.e. bilirubin, AST, ALT all 10g/dl, WCC > 3x109/l, platelets > 150x109/l) and normal clotting (INR and APTT <1.2) 10. Patients must agree not to father a child within 12 months following AdNRGM administration, and must practice a barrier method of contraception starting from the time of AdNRGM administration for at least 12 months 11. No known immunoincompetence
Exclusion criteria
Exclusion criteria: 1. Patients with a prostate or tumour which is deemed clinically unsuitable for transperineal templateguided injection 2. Patients who have previously been treated with prostate brachytherapy 3. Patients who have received chemotherapy, radiotherapy or immunotherapy within 28 days of study entry 4. Acute active infection (viral, bacterial, or fungal) which requires specific therapy 5. Chronic hepatitis B or C infection, HIV positive patients (patients will be tested for HBV/HCV, but not HIV) 6. Concurrent severe medical illnesses incompatible with the treatment including psychiatric pathology likely to affect protocol compliance 7. Tumours of other organs or tissues still active or treated radically less that 3 years before (except that successfully treated, nonmetastatic skin cancers are not an exclusion criterion) 8. Concurrent corticosteroids, or any medication known to have significant immunosuppressive action 9. Patients unable to travel for regular hospital assessments 10. Evidence of adenovirus infection and/or shedding at prescreening
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measures as of 26/07/2016: 1. Safety and tolerability of escalating doses of AdNRGM, followed by iv CB1954 determined by assessing local effects on tumour etc. and number of participants with treatment related adverse events by CTCAE v4.0 (Time Frame: 12 months) 1.1. Safety will be assessed in terms of local effects on the tumour, the prostate gland and the lower urinary tract as well as in terms of systemic effects. The data will be summarised descriptively 1.2. Adverse events and side effects will be determined as changes of the relevant clinical parameters as well as changes of haematological and clinical biochemistry data Previous primary outcome measures: Toxicity; timepoint(s): up to end of Month 11 visit | — |
Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 26/07/2016: 1. PSA levels and PSA kinetics following treatment with AdNRGM and CB1954 (time frame: 12 months). Changes in the level and kinetics of the serum PSA will be measured to provide an indication of changes in tumour burden, growth rate and possible anti-tumour activity of the treatment. Other pre-specified outcome measures: 2. Evidence for local tumour destruction, and immune infiltration, in tumour biopsies taken after the treatment (time frame: 12 months). Treatment-induced immune responses will be assessed by measurement of T cell responses to prostate cancer antigens in blood samples collected at baseline and at intervals (2, 3, 4, and 8 weeks) following treatment. 3. Changes in cellular immune response to prostate cancer antigens following treatment with AdNRGM and CB1954 (time frame: 12 months). Evidence of tumour destruction and immune infiltration will be assessed by looking at patterns of tissue damage, residual tumour tissue and immune cell infiltrates detected by immunohistochemistry in post-treatment prostate biopsies Previous secondary outcome measures: PSA level and kinetics; timepoint(s): Up to end of Month 11 | — |
