Viadur (Leuprolide Acetate) - Summary

 
 



VIADUR SUMMARY

Viadur® (leuprolide acetate implant)

Viadur® (leuprolide acetate implant) is a sterile nonbiodegradable, osmotically driven miniaturized implant designed to deliver leuprolide acetate for 12 months at a controlled rate (Figure A). Viadur® incorporates DUROS® technology. The system contains 65 mg of leuprolide (free base). Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin-releasing hormone (GnRH or LH-RH). The analog possesses greater potency than the natural hormone. The implant is inserted subcutaneously in the inner aspect of the upper arm. After 12 months, the implant must be removed. At the time an implant is removed, another implant may be inserted to continue therapy.

Viadur® is indicated in the palliative treatment of advanced prostate cancer.

Published Studies Related to Viadur (Leuprolide)

A phase III extension trial with a 1-arm crossover from leuprolide to degarelix: comparison of gonadotropin-releasing hormone agonist and antagonist effect on prostate cancer. [2011.09]
PURPOSE: We investigated the efficacy and safety of degarelix treatment and the effects of switching from leuprolide to degarelix in an ongoing extension study with a median 27.5-month followup of a pivotal 1-year prostate cancer trial... CONCLUSIONS: Data support the statistically significant prostate specific antigen progression-free survival benefit for degarelix over leuprolide seen during year 1 and the use of degarelix as first line androgen deprivation therapy as an alternative to a gonadotropin-releasing hormone agonist.

A randomized trial of microdose leuprolide acetate protocol versus luteal phase ganirelix protocol in predicted poor responders. [2011.06.30]
We performed a randomized trial to compare IVF outcomes in 54 poor responder patients undergoing a microdose leuprolide acetate (LA) protocol or a GnRH antagonist protocol incorporating a luteal phase E(2) patch and GnRH antagonist in the preceding menstrual cycle.

Hot flushes in prostatic cancer patients during androgen-deprivation therapy with monthly dose of degarelix or leuprolide. [2011.06]
The aim of the study was to compare the onset, incidence and frequency/intensity of hot flushes during androgen-deprivation therapy with a gonadotropin-releasing hormone antagonist (GnRH) blocker versus an agonist using data from a randomized Phase 3 clinical trial...

Randomized trial of leuprolide versus continuous oral contraceptives in the treatment of endometriosis-associated pelvic pain. [2011.04]
OBJECTIVE: To compare the efficacy of leuprolide and continuous oral contraceptives in the treatment of endometriosis-associated pain...

Effects of metformin and leuprolide acetate on insulin resistance and testosterone levels in nondiabetic postmenopausal women: a randomized, placebo-controlled trial. [2010.11]
OBJECTIVE: To determine whether insulin sensitizers lower androgen levels and whether androgen suppression improves insulin resistance in nondiabetic postmenopausal women... They confirm that treatment of insulin resistance decreases T production in this population and demonstrate that pharmacologic lowering of T does not affect insulin resistance.

Clinical Trials Related to Viadur (Leuprolide)

Adjuvant Leuprolide With or Without Docetaxel in High Risk Prostate Cancer After Radical Prostatectomy [Active, not recruiting]
Primary Objective :

- The primary objective of the study is to compare progression-free survival (PSA

progression after systemic treatment, radiologically or histologically documented progression after systemic treatment or death from any cause, whichever occurs first), using a 2x2 factorial design among treatment groups as follows:

- Immediate treatment following prostatectomy versus deferred treatment at the time

of relapse

- Docetaxel q3w plus leuprolide acetate versus leuprolide acetate alone

Secondary Objectives :

- To compare the 5-year overall, cancer-specific and metastasis-free survival

(metastasis-free survival based on time to clinical evidence of metastasis evidenced by physical exam or radiologically on bone scan or CT scan) after systemic treatment between the groups defined as follows:

- Immediate treatment following prostatectomy versus deferred treatment

- Docetaxel q3w plus leuprolide acetate versus leuprolide acetate alone

- To compare the safety and tolerability between Docetaxel in combination with leuprolide

acetate and leuprolide acetate alone.

- To evaluate quality of life as measured by the FACT-P questionnaire.

A Six-Month, Open-Label, Crossover Study Of the Maintenance Of Serum Testosterone And PSA Suppression After Switching Between Lupron 22.5 Mg And Eligard 22.5 Mg Or Zoladex 10.8 Mg And Eligard 22.5 Mg In Patients With Advanced Prostate Cancer [Completed]
Comparing the effect of switching from Lupron and Zoladex to Eligard. PSA and Testosterone levels are measured at set intervals to determine if Eligard is equal or better then Lupron or Zoladex in advanced Prostate Cancer patients.

Endometrial Markers and Response of Endometriosis Patients to Prolonged GnRH Agonist Prior to IVF [Completed]
This prospective randomized trial evaluates whether one can predict which infertile women with endometriosis who are candidates for in vitro fertilization will benefit from prolonged therapy with a GnRH agonist by the determination of the absence of endometrial expression of the integrin, alpha v, beta 3 vitronectin. This is a prospective randomized trial in which all patients will undergo endometrial biopsy prior to initiation of ovarian stimulation for in vitro fertilization and then undergo randomization to a three month course of a depot preparation of the GnRH agonist leuprolide acetate in depot suspension prior to ovarian stimulation or standard therapy. prio

Neoadjuvant Abiraterone Acetate Plus Leuprolide Acetate in Men With Localized High Risk Prostate Cancer [Recruiting]
The purpose of this research study is to determine the effects of abiraterone acetate plus leuprolide acetate and prednisone versus leuprolide acetate alone on hormone levels in the blood and prostate. For this study, patients are required to be suitable candidates for a radical prostatectomy (prostate surgery) which will be performed after 24 weeks of treatment.

Study of (1) Everolimus, (2) Estrogen Deprivation Therapy (EDT) With Leuprolide + Letrozole and (3) Everolimus + EDT in Patients With Unresectable Fibrolamellar Hepatocellular Carcinoma (FLL-HCC) [Recruiting]
There is no effective standard treatment for fibrolamellar liver cancer that cannot be removed by surgery. The investigators want to find out what effects, good and/or bad, 3 drugs called letrozole, leuprolide and everolimus will have on cancer. All of these drugs are FDA approved for the treatment of different cancers. Letrozole and leuprolide stop the body from producing estrogen, a normal hormone produced by the body. Too much estrogen may help fibrolamellar liver cancer grow. Everolimus is a drug that may block other chemicals in the body that can help cancer grow. The combination of letrozole and leuprolide plus everolimus may work well together.
