Standard Moderately Hypofractionated RT vs. Ultra-hypofractionated Focal Lesion Ablative Microboost in Prostate Cancer

Start date: February 1, 2023
Phase: N/A
Study type: Interventional

EBRT is one of the standard treatment options for patients with localized PCA. Based on the outcome of randomized trials, moderately hypofractionated RT(19-25 fractions of 2.5-3.4Gy) is considered equivalent to conventional fractionated schemes with 35-39 fractions of 2Gy. A schedule of 20 fractions to a dose of 60-62Gy is adopted as standard of care for all risk-groups. Driven by the success of moderate hypofractionation, there is a strong trend towards extreme hypofractionation, also called SBRT, reducing the number of fractions even further. The schedule mostly used is 5 fractions of 7-7.25Gy. Its effectiveness, equivalence to standard EBRT schedules, has been demonstrated for low and favourable intermediate risk (IM) patients. For unfavourable IM (here defined as IM with ISUP grade 3) and high-risk (HR) PCA the outcome of EBRT can be further improved by dose escalation. Because of dose-limiting toxicity, the maximal dose of EBRT for conventionally fractionated schemes was approximately 80Gy. Initially hypofractionation was considered as a potential way to escalate the biologically effective dose (BED) above 80Gy, however, this proved not to be the case. With hypofractionation, a saturation in dose effect seems to be present at a BED of 80Gy. Recently, the multi-centre phase III FLAME trial broke the '80Gy barrier' and showed that in mainly HR PCA patients, treated with a conventional fractionation schedule, focal boosting of the intraprostatic lesion to a total dose of 95Gy improves biochemical disease-free survival (bDFS). However, given the advantages of hypofractionation in terms of patient comfort and costs, the FLAME schedule is not ideal as the standard treatment. For unfavourable IM and HR PCA patients the value of SBRT has not yet been established. The FLAME trial showed that higher than standard BED is a prerequisite for optimal bDFS. Furthermore, post SBRT biopsies results suggest a dose response relationship with better outcome of dose levels above 40Gy. Therefore, probably a higher than standard dose SBRT is necessary for these patients. A recent meta-analysis suggests diminishing results from increased fraction sizes in SBRT. So, the question remains whether dose escalation in SBRT will indeed improve treatment outcome. With standard SBRT to the whole prostate, dose escalation is limited to 40Gy because of unacceptable toxicity. In line with FLAME, we conducted the Hypo-FLAME trial investigating focal dose escalation in SBRT. In the phase II Hypo-FLAME trial, 100 patients with IM or HR PCA were treated with SBRT 35Gy in 5 weekly fractions to the whole prostate with a focal boost up to 50Gy. The acute toxicity rates, the primary endpoint, were low and similar to standard SBRT indicating this schedule can be safely applied. Given this was a phase II trial, no conclusions on oncological outcome can be drawn. Shortening of the overall treatment time (OTT) has been suggested to play a role in SBRT efficacy and 5 fractions delivered every other day this is internationally accepted as standard. We therefore initiated the phase II Hypo-FLAME 2.0 trial, investigating the feasibility of a reduction in the OTT of the Hypo-FLAME schedule from 29 to 15 days with acute toxicity as primary endpoint. The accrual of this trial is completed and a first analysis of the primary endpoint shows low toxicity figures, well in the range of what was expected. We expect to submit the analysis for publication by the end of 2022. At present, it is unknown what the oncological efficacy of the Hypo-FLAME schedule is compared to the standard of care in unfavourable IM and HR prostate cancer. Therefore, we will conduct a Phase III multi-centre randomized trial, in which 484 patients with unfavourable IM or HR PCA will be randomized between: 1. Standard treatment; moderately hypofractionated radiotherapy 62 Gy in 20 fractions of 3.1Gy 2. Experimental treatment; SBRT 5x7Gy with an iso-toxic integrated focal boost up to 50 Gy (Hypo-FLAME).

Hypoxia-driven Prostate Cancer Genomics (HYPROGEN)

HYPROGEN
Start date: October 3, 2021
Phase:
Study type: Observational

Due to the rapid growth, tumour demand for oxygen is often higher than what can be delivered by the newly forming blood vessels. Tumour adaption to this imbalanced oxygen supply and demand (hypoxia) is associated with poor prognosis and genetic changes (genomic instability) that allow it to become more resistant to chemo- and radiotherapy. Patients with hypoxic tumours therefore die earlier. Limited information is available on hypoxia in newly diagnosed prostate cancer, especially to what degree hypoxia in the prostate tumour is associated with the presence of metastases to bones. The Hyprogen trial is a prospective, non-randomised, exploratory biopsy and imaging biomarker study recruiting 60 patients with prostate cancer to better establish the role of hypoxia in prostate cancer cells evolution and early metastatic spread.

Contributions to Hypertension With Androgen Deprivation Therapy

ARCH
Start date: April 1, 2023
Phase: Phase 4
Study type: Interventional

This study plans to learn more about contributors to high blood pressure in men who undergo androgen deprivation therapy (ADT) to treat prostate cancer. Prostate cancer is the most common non-skin cancer in men, affecting approximately 1 in 8 American men and its primary treatment is through the use of ADT. However, ADT increases the likelihood of developing heart disease including high blood pressure. This study will determine if dysfunction of the nervous system and/or kidneys occurs in men undergoing ADT, as these systems play a significant role in control of blood pressure. The results from this study will help us understand the ways in which ADT contributes to heart disease and help us develop therapies to prevent heart disease in prostate cancer survivors.

TRANBERG® Transperineal MR/US Fusion Laser--Induced Thermal Therapy for Men With Prostate Cancer

TPF-LITT
Start date: March 16, 2022
Phase: N/A
Study type: Interventional

This study is set up as a phase I prospective, single center, device interventional pilot study carried in office setting under local anesthesia. It will assess the tolerance and safety of target fusion ablation of prostate cancer tumors using Laser Induced Thermal Therapy (TFA-LITT) guided by fusion imaging in men 50 to 80 years of age with low to intermediate risk prostate cancer Prostate Cancer is currently managed with in a discrete fashion where patients either enroll in active surveillance protocols (No intervention) or undergo full intervention via whole gland treatments - most commonly radical surgery or radiation. These treatments have not shown definitive gains in all cause survival and not uncommonly harbor undesirable adverse effects, most notably: impotency and incontinence. Such events elicit significant and noticeable changes on a male lifestyle and for most prostate cancer tumors are considered overtreatment. This study aims to evaluate the use of TFA-LITT in the office setting under local anesthesia - greatly decreasing patient perioperative surgical risk - focused on the organ sparing cancer lesion ablation, where organ function is preserved. The fundamental objective is to determine the tolerance and safety of TFA-LITT in men with low to intermediate risk prostate cancer, successful performed in the outpatient office-based setting under local anesthesia directed by fusion imaging. Secondary objectives include: 1-Biopsy proven cancer control of ablated areas 12 months after procedure; 2-Uroflowmetry and urinary function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 3- Sexual function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 4- MRI changes of ablated area one, three and 12 months after TFA-LITT; 5- Absence or presence of ejaculation after TFA-LITT.
