About this study
Official title: Phase II Study Evaluating HSV-tk + Valacyclovir Gene Therapy in Combination With Androgen Deprivation Therapy, Brachytherapy, External Beam Radiotherapy, and Prostatectomy for High-Risk Prostate Cancer
This is a prospective phase II study to assess the efficacy and toxicity of HSV-tk+ valacyclovir gene therapy in combination with androgen deprivation therapy, brachytherapy, external beam radiotherapy, and prostatectomy in previously untreated high-risk prostate cancer.
Read the detailed description
This phase II study plans to assess efficacy and toxicity of HSV-tk+ valacyclovir gene therapy in combination with androgen deprivation therapy, brachytherapy, external beam radiotherapy, and prostatectomy in previously untreated high-risk prostate cancer patients.
Clinical response as evaluated by changes in serum PSA level and digital rectal examination as well as by histological alterations on re-biopsy and prostatectomy such as the presence of apoptosis, necrosis, tumor proliferation and immunologic response, will be assessed following HSV-tk + valacyclovir treatment. Blood samples will be taken for systemic immunological response, blood counts and liver functions tests. Toxicity will be graded by the Common Terminology Criteria for Adverse Events (CTCAE) and Radiation Therapy Oncology Group (RTOG) neuro-toxicity scores (See Appendices). Additionally, patients will be followed closely to assess nadir PSA, freedom from PSA-progression, and freedom from local and distant progression and overall survival.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HSV-TkDrug
Also called Gene therapy, AdV-tk gene therapy, Herpes simplex virus thymidine kinase
Injection of the HSV-tk gene therapy product in four quadrants of prostate to enhance the immune system via "bystander effect" in which cytotoxicity is conferred to non-transduced neighboring cells. In vivo bystander effects are likely due to a combination of host immunological responses and to gap junction-mediated transport of phosphorylated prodrug metabolites to surrounding cells.
ValacyclovirDrug
Also called Valtrex
The recommended dose for this trial is 2 g orally t.i.d. for 14 days (day 1 to day 15 and days 31 to 45). This dose has been calculated to give a similar AUC as 10 mg/kg of intravenous acyclovir administered every 8 hours. This is the same dose regimen used in a previous phase I clinical trial of ADV/HSV-tk plus acyclovir and topotecan in patients with recurrent ovarian cancer.
BicalutamideDrug
Also called Casodex
The recommended dose for Bicalutamide therapy in combination with an LHRH analogue is one 50 mg tablet once daily (morning or evening), with or without food. It is recommended that Bicalutamide be taken at the same time each day.
The use of an oral antiandrogen with medical castration for the treatment of prostate cancer is referred to as combined androgen blockade (CAB). Compared with LHRH-agonist monotherapy, CAB with bicalutamide did not reduce overall QoL but provided an early improvement in QoL related to lower urinary tract symptoms and pain.
Leuprolide AcetateDrug
Also called Lupron
Leuprolide acetate 7.5 mg depot injection will be injected monthly for a total of 2 months.
Brachytherapy, External beam radiotherapyRadiation
Also called HDR, EBRT
On day 60, patient will undergo high dose rate (HDR) Brachytherapy. The patient will have 8-14 needle catheters inserted under ultrasound guidance. CT simulation and radiation treatment planning will be performed. The needle catheters will be connected to an HDR afterloader containing an Iridium 192 source. A single dose of 1250cGy will be delivered.
Radical prostatectomyProcedure or surgery
Also called Prostatectomy
approximately 2-3 weeks after radiotherapy completion, patient will undergo radical retropubic prostatectomy. Use of laparoscopy or robotic assistance will be at the urologist's discretion. Lymph node dissection will be performed.
| Study group | Role | What they receive |
|---|---|---|
| Gene Therapy, ADT, RT, and Surgery | Experimental | The investigational gene therapy, ADV/HSV-tk, will be administered by injection into the prostate at 5 x 10[11] virus particles (1.25 x 10[11] virus particles per tumor quadrant in 4 quadrants) on day 0 and day 30.
The recommended dose of Valacyclovir for this trial is 2 g orally t.i.d. for 14 days (day 1 to day 15 and days 31 to 45).
The recommended dose for Bicalutamide therapy in combination with an LHRH analogue is one 50 mg tablet once daily (morning or evening).
Leuprolide acetate 7.5mg depot injection will be injected monthly for a total of 2 months. Receives: Drug: HSV-Tk; Drug: Valacyclovir; Drug: Bicalutamide; Drug: Leuprolide Acetate; Radiation: Brachytherapy, External beam radiotherapy; Procedure: Radical prostatectomy |

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing HSV-Tk, Valacyclovir and Bicalutamide in people with High-risk Prostate Cancer and Prostate Cancer, run by The Methodist Hospital Research Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 6 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Emily Hsiao, Ph.D. (713-383-5115, khsiao@houstonmethodist.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Biochemical control rate (time frame: 5-year biochemical disease free survival rate). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03541928, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Apr 2021.
