VANTAS SUMMARY
Vantas Implant
Vantas™ (histrelin implant) is a sterile non-biodegradable, diffusion-controlled reservoir drug delivery system designed to deliver histrelin continuously for 12 months upon subcutaneous implantation. The Vantas implant contains 50 mg of histrelin acetate. Histrelin acetate is a synthetic nonapeptide analogue of the naturally occurring gonadotropin releasing hormone (GnRH) or luteinizing hormone releasing hormone (LH-RH). The sterile Vantas implantation device (provided with the implant) is used to insert the implant subcutaneously in the inner aspect of the upper arm. After 12 months, the implant must be removed. At the time the implant is removed, another implant may be inserted to continue therapy.
Vantas is indicated in the palliative treatment of advanced prostate cancer .

UroToday.com - Gonadotrophin-releasing hormone (GnRH) agonists are currently the 'standard of care' for androgen deprivation therapy (ADT) in prostate cancer. Improvements in ADT would have a great value for many patients. The agonists are associated with an initial testosterone surge, which delays castration and may stimulate tumor growth and induce 'clinical flare' in patients with symptomatic advanced disease.
Published Studies Related to Vantas (Histrelin Implant)
Efficacy and safety of histrelin subdermal implant in children with central precocious puberty: a multicenter trial. [2007.05]
CONTEXT: GnRH analog (GnRHa) therapy for central precocious puberty (CPP) typically involves im injections. The histrelin implant is a new treatment that provides a continuous slow release of the GnRHa histrelin. OBJECTIVE: The objective of the study was to investigate the safety and efficacy of the subdermal histrelin implant for the treatment of CPP in treatment naive and previously treated children... CONCLUSIONS: The subdermal histrelin implant achieves and maintains excellent suppression of peak LH and sex steroid levels for 1 yr in children with CPP. The treatment is well tolerated. Long-term studies are needed to confirm these results.
Efficacy and Safety of Histrelin Subdermal Implant in Children with Central Precocious Puberty: A Multicenter Trial. [2007.02.27]
Context: Gonadotropin- releasing hormone analog (GnRHa) therapy for central precocious puberty (CPP) typically involves intramuscular injections. The histrelin implant is a new treatment that provides a continuous slow release of the GnRHa histrelin...
Efficacy and safety of histrelin subdermal implant in patients with advanced prostate cancer. [2006.04]
PURPOSE: This open label, multicenter study was done to evaluate the efficacy and safety of the gonadotropin hormone-releasing hormone agonist histrelin acetate administered as a 50 mg subdermal implant in men with advanced prostatic cancer... CONCLUSIONS: The gonadotropin hormone-releasing hormone agonist histrelin acetate provided in a unique implant delivery device is effective for treating men with advanced prostate cancer, as demonstrated by the suppression of testosterone and LH to castrate levels at 4 weeks and the maintenance of these levels during 52 weeks. PSA, a secondary end point for effectiveness, was also suppressed significantly from baseline.
The histrelin implant: a novel treatment for central precocious puberty. [2005.12]
OBJECTIVE: Standard treatment of central precocious puberty (CPP) consists of intramuscular or subcutaneous administration of a gonadotropin-releasing hormone (GnRH) agonist (GnRHa) at 3- to 4-week intervals. Although generally effective in suppressing clinical and laboratory parameters of puberty, GnRHa injections are painful, and the need for monthly clinic visits may contribute to poor compliance. Recently, a subcutaneous implant was developed that releases the GnRHa histrelin at an average rate of 65 microg/day. The aims of this study were to determine if a histrelin implant would suppress gonadotropin and estradiol (E2) in girls with CPP for 1 year and to compare the suppression to standard treatment... CONCLUSIONS: The histrelin implant consistently suppresses clinical and laboratory parameters of puberty for 1 year and is a promising new technique for treating CPP without the pain and inconvenience of monthly injections.
An evaluation of the pharmacokinetics and pharmacodynamics of the histrelin implant for the palliative treatment of prostate cancer. [2005.11]
