Trial Outcomes & Findings for Radiation Therapy and Docetaxel in Treating Patients Who Are Undergoing Surgery for Localized Prostate Cancer (NCT NCT00321698)
NCT ID: NCT00321698
Last Updated: 2024-08-29
Results Overview
Maximal tolerated dose (MTD) of the combination radiation (45 Gy) and docetaxel. The dose of radiation will be fixed at 45 Gy while the dose of docetaxel will be escalated. The starting dose of docetaxel will be 10 mg/m2 and will be escalated in increments of 10 mg/m2 up to a dose of 30 mg/m2 the pre-planned ceiling). MTD will be the dose that is associated with no more than 1 dose limiting toxicity (DLT) up to 6 patients. The DLT will be defined as clinically significant grade 3 non-hematologic or grade 4 hematologic toxicity, attributable to the chemoirradiation. If 2 of 3 patients experience a DLT, dose escalation will stop and the previous dose level will be considered the MTD. If 1 of 3 has DLT, additional 3 patients will be enrolled at the same dose level. If none of the additional 3 patients has DLT, the dose escalation will continue. If 1 additional patient has DLT, the previous dose will be considered the MTD and dose escalation will be stopped.

Participant Flow
Subject accrual from Urology clinics started in April 2006; annual follow-up of 22 VA, 3 Oregon Health \& Science University (OHSU) (25 total) subjects who completed ended in 2011; 10 year follow-up of these patients will be completed in 2021.
Our 1 screen failure was excluded as a result of having a different type of cancer, other than non-melanoma skin cancer, within the past 5 years.

PRIMARY outcome
Timeframe: 5 weeksPopulation: Outcome analysis includes the subjects from all 4 phase I groups, inclusive of subjects who only received radiation, as all subjects across all phases received the same radiation dosage. Phase I, group 1 subjects were included in case MTD was zero.
Maximal tolerated dose (MTD) of the combination radiation (45 Gy) and docetaxel. The dose of radiation will be fixed at 45 Gy while the dose of docetaxel will be escalated. The starting dose of docetaxel will be 10 mg/m2 and will be escalated in increments of 10 mg/m2 up to a dose of 30 mg/m2 the pre-planned ceiling). MTD will be the dose that is associated with no more than 1 dose limiting toxicity (DLT) up to 6 patients. The DLT will be defined as clinically significant grade 3 non-hematologic or grade 4 hematologic toxicity, attributable to the chemoirradiation.

PRIMARY outcome
Timeframe: 4-6 weeks after study treatmentPathologic response rate is determined post-prostatectomy by pathologist laboratory analyses. The TNM system is the most widely used cancer staging system. Most hospitals and medical centers use the TNM system as their main method for cancer reporting. In the TNM system: The T refers to the size and extent of the main/primary tumor. T1, T2, T3, T4: Refers to the size and/or extent of the main tumor. The higher the number after the T, the larger the tumor or the more it has grown into nearby tissues. T's may be further divided to provide more detail, such as T3a and T3b.

SECONDARY outcome
Timeframe: Baseline (pre-treatment) and 1 month after surgery (post-treatment)Population: Pre- and post-treatment PSA values were available in 22 of 25 patients.
All participants were combined for this assessment as pre-specified in the protocol. The percentage change for patients were determined from pre- and post- treatment PSA values. The mean percentage change in PSA will be reported. PSA will be monitored every 3-6 months during the first 5 years, then annually after surgery for up to 10 years

SECONDARY outcome
Timeframe: Regular intervals both study-related and clinical standard of care-related; assessed at end of study treatment. Average timeframe to follow safety was 1 year and includes all grade 3-4 adverse eventsPopulation: Phase I participants numbered 12 (receiving different chemotherapy doses) and Phase II participants numbered 13 (receiving the maximally tolerated chemotherapy dose). This Outcome Measure was assessed in aggregate, combining participants from both phases of the study, per protocol.
An adverse event is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure.

The following men per chemotherapy dosage experienced a detectable or rising PSA value after surgery with a 2nd confirmatory level of 0.2ng/mL or higher (defined as biochemical recurrence of prostate cancer).
Biochemical Recurrence is defined as a detectable or rising PSA value after surgery that is 0.2 ng/mL or greater with a second confirmatory level of 0.2 ng/mL or greater.

SECONDARY outcome
Timeframe: 5 weeksPopulation: For Phase I Dose 1-4, all participants were combined for this assessment as pre-specified in the protocol.
Pathologic response rate is determined post-prostatectomy by pathologist laboratory analyses. The TNM system is the most widely used cancer staging system. Most hospitals and medical centers use the TNM system as their main method for cancer reporting. In the TNM system: The M refers to whether the cancer has metastasized. This means that the cancer has spread outside of the primary tumor to other parts of the body.

SECONDARY outcome
Timeframe: Baseline and 12 Months Post-ProstatectomyPopulation: Scores not available for some participants
Mean change in score from Baseline to 12-months pot-op. A single outcome, Health Related Quality of Life (QOL), was specified in the protocol. All 6 score means and confidence intervals are reported here as a single outcome; a separate row for each score. AUA Symptom Score is designed to measure lower urinary tract symptoms (LUTS) resulting from benign prostatic hyperplasia or other causes in men. Higher scores indicate more LUTS (scale 0-35). 1-7, mild; 8-19, moderate; 20-35, severe. EPIC quality of life instruments is a 32-item self-report questionnaire that measures the QOL of prostate cancer patients. 4 subscales measuring urinary (further consisting of two sub-components, EPIC Urinary Incontinence Score and EPIC Urinary Obstructive/Irritative Score), bowel, sexual and hormonal changes. Scores for each of the subscales, as well as for each sub-component within the Urinary sub scale, are transformed linearly to a 0-100 scale with higher scores representing better QOL.
