Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Other - Gene Directed Enzyme Prodrug Therapy, FP253/Fludarabine

Experimental: 1 - Six Cohorts with escalating vector dose


Treatment: Other: Gene Directed Enzyme Prodrug Therapy, FP253/Fludarabine
Subjects within a treatment group will be administered a single transrectal intraprostatic injection of FP253.

Group A: 1 x 10Exp9 virus particles (VP); Group B: 3.2 x 10Exp9 VP; Group C: 1 x 10Exp10 VP; Group D: 3.2 x 10Exp10 VP; Group E: 1 x 10Exp11 VP; Group F: 3.2 x 10Exp 11 VP.

If there are no dose-limiting toxicities, three additional patients may be treated at the highest dose.

Twenty four hours following administration of the FP253, subjects will receive a first dose of fludarabine phosphate (20mg/m2 administered as an intravenous bolus). The first dose of fludarabine phosphate will be followed by 4 further doses at 24 hour intervals on treatment Days 3 to 6.

Eligibility
Key inclusion criteria
Inclusion Criteria (Prostate Cancer Categorization):

Subjects will have adenocarcinoma of the prostate which is progressive despite androgen deprivation therapy.

Subjects MUST fulfil each of the following criteria for inclusion in this study:

1. Biopsy of the tumour must have been performed and histological status of adenocarcinoma of the prostate documented. The diagnostic prostatic biopsy will have taken place at least 4 weeks prior to the planned day 1.
2. Subjects will have their prostate in situ.
3. Biochemical evidence of prostate cancer recurrence; defined as a rise over 3 successive PSA measurements spanning a minimum of 3 months (no lower limit of PSA exclusion).
4. Subjects will have been treated with androgen deprivation therapy and will remain on hormone therapy for the duration of the study (LHRH agonists with or without antiandrogens, or bilateral orchidectomy).
5. The Investigator should be able to localise the tumour either by digital rectal examination (DRE) (i.e. tumour palpable); or the tumour should be visible on transrectal ultrasound (TRUS). Localization of tumour will be documented and should be adequate to allow the Investigators to inject it. Repeated TRUS will be at the discretion of the Investigator General.

Inclusion Criteria (General):

Subjects MUST fulfil each of the following criteria for inclusion into this study:

1. Be male and be 18 years of age or greater.
2. Have voluntarily given written informed consent to participate in this study.
3. Have an ECOG performance status of 0, 1 or 2.
4. Have agreed to remain confined to the clinical testing facility for the first 3 days (2 nights) of the study.
5. Have adequate baseline organ function.
6. Have an ECG which is normal, or, if there is any abnormality, it must be considered to be clinically insignificant in the context of the trial.

Key exclusion criteria
Exclusion Criteria (Prostate Cancer Categorization):

Subjects with any of the following criteria will NOT be eligible for participation in this study:

1. Subjects who have had prior radical prostatectomy.
2. Subjects who are expected to die of prostate cancer within 3 months.

Exclusion Criteria (General):

Subjects with any of the following criteria will NOT be eligible for participation in this study:

1. Hypersensitivity to ciprofloxacin, fludarabine, pegfilgrastim or similar compounds.
2. Contraindications to fludarabine: subjects with decompensated haemolytic anaemia.
3. Contraindications to pegfilgrastim: known hypersensitivity to E. coli derived products.
4. Other associated or concomitant medical conditions that would interfere with the conduct of the study in the opinion of the treating physician.
5. Have used an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of study medication.
6. Are immunocompromised or have used immunomodulatory agents/therapy within the 6 months preceding the initial treatment.
7. Subjects who, at the sole discretion of the Investigator, are judged to be unsuitable for participation in the study.
