Overview

Buserelin is a synthetic gonadotropin-releasing hormone (GnRH) analog which is more potent than natural GnRH. It is an effective treatment for inducing frequent and meaningful remissions in advanced prostatic cancer.

ExcerptReferenceRelevance
"Buserelin is a GnRH agonist peptide drug, comprising a nine amino acid sequence (pGlu-His-Trp-Ser-Tyr-D-Ser(tBu)-Leu-Arg-Pro-NH-Et) and most commonly known for its application in hormone dependent cancer therapy, e.g. "( Dry heat forced degradation of buserelin peptide: kinetics and degradant profiling.

Bioavailability

Dosage Studied

Buserelin (d-Ser-[TBU]6 LHRH ethylamide) was prescribed in two different dosage schedules to twenty men, and in a single dosage schedule to eight women. Similar dose-response relationships were found for LH-RH and buserelin as concerns the release of luteinizing hormone (LH) by pituitary glands from intact and ovariectomized rats.

Percentage of Participants Experiencing Late Grade 2+ and 3+ Adverse Events > 90 Days From the Completion of Radiotherapy (RT)

Common Terminology Criteria for Adverse Events (version 3.0) grades adverse event severity from 1=mild to 5=death. Late adverse events (AE) are defined as occurring > 90 days from the completion of RT. Failure time is defined as time from randomization to the date of first late grade 2 or grade 3 adverse event, death (competing risk), or last known follow-up (censored). Failure rates for data summary are estimated using the cumulative incidence method, with 5-year rates provided here. Pairwise comparisons of the distributions of failure times between Arm 2 and Arm 1 and between Arm 3 and Arm 2, reported in the statistical analysis section, use cause-specific hazard rates for which deaths are censored. (NCT00567580)
Timeframe: AE: from 91 days after completion of RT (approximately 7-8 weeks) to last follow-up. Vital status: from randomization to last follow-up. Maximum follow-up at time of analysis was 10.5 years.

Secondary biochemical (failure) is defined as either of two occurrences: 1. For detectable post-baseline PSA values (≥ 0.1), the first occurrence of a PSA value that is both ≥ 0.4 and a second rise above nadir; 2.The start of second salvage therapy. Failure time is defined as time from randomization to the date of failure, death (competing risk), or last known follow-up (censored). Failure rates for data summary are estimated using the cumulative incidence method, with 5-year rates provided here. Pairwise comparisons of the distributions of failure times, reported in the statistical analysis section, use cause-specific hazard rates for which deaths are censored. The study was designed for the final analysis to occur after all participants had been on study for at least 5 years, but results were reported early. See Limitations and Caveats section.

Percentage of Participants Free From Progression (FFP) at 5 Years

Progression is defined as the first occurrence of the following events: biochemical failure by the Phoenix definition (prostate-specific antigen [PSA] ≥ 2 ng/ml over the nadir PSA), clinical failure (local, regional or distant), or death from any cause. The initiation of second salvage therapy before progression was a protocol violation and resulted in censoring. Progression time is defined as time from randomization to the date of progression, second salvage therapy (censored), or last known follow-up (censored). Freedom from progression rates are estimated using the Kaplan-Meier method. The study was designed for the final analysis to occur after all participants had been on study for at least 5 years, but results were reported early. See Limitations and Caveats section.

Failure rates for data summary are estimated using the cumulative incidence method, with 5-year rates provided here.

Change is calculated as time point value - baseline value, such that a positive change indicates improvement. (NCT00936390)
Timeframe: Last week of RT (approximately 9 and 17 weeks from start of protocol treatment for Arm 1 and 2, respectively), then 6 months, 1 year and 5 years from end of RT.

Change From Baseline in Patient Reported Outcome Measurement Information System (PROMIS) Fatigue Domain Score

The PROMIS Fatigue short form 8a contains 8 questions, each with 5 responses ranging from 1 to 5, evaluating self-reported fatigue symptoms over the past 7 days. The total score is the sum of all questions which is then converted into a pro-rated T-score with a mean of 50 and standard deviation of 10, with a possible range of 33.1 to 77.8. Higher scores indicate more fatigue. Change is defined as value at one year - value at baseline. Positive change from baseline indicates increased fatigue at one year. (NCT00936390)

Change in Patient-reported Quality of Life as Measured by Expanded Prostate Cancer Index Composite (EPIC) Short Form at One Year

The EPIC-Short Form is a 26-item, validated self-administered tool to assess disease-specific aspects of prostate cancer and its therapies consisting of five summary domains (bowel, urinary incontinence, urinary irritation/obstruction, sexual, and hormonal function). Responses for each item form a Likert scale which are transformed to a 0-100 scale. A domain score is the average of the transformed domain item scores, ranging from 0-100 with higher scores representing better health-related quality of life (HRQOL). Change at one year is defined as one-year value - baseline value. Positive change at one year indicates improved quality of life. (NCT01546987)
