OBJECTIVES: Gonadotropin-releasing hormone agonists are widely used as androgen
deprivation therapy in many men with locally advanced or metastatic prostate
cancer. Gonadotropin-releasing hormone agonists are delivered by intramuscular
injection every 1, 3 or 6 months, but in some patients subcutaneous injection may
be more appropriate. This study assessed the efficacy and safety profile of the
gonadotropin-releasing hormone agonist, triptorelin pamoate, when administered by
the subcutaneous route. METHODS: In this multicentre, open-label, single-arm
study, androgen deprivation therapy-naïve men with locally advanced or metastatic
prostate cancer received the gonadotropin-releasing hormone agonist triptorelin
pamoate 11.25 mg (3-month formulation) by the subcutaneous route twice (at
baseline and 13 weeks later). The co-primary efficacy endpoints were the
proportion of patients with a castration level of serum testosterone (<50 ng/dl)
after 4 weeks, and of these, those still castrated after 26 weeks. RESULTS: Of
the 126 treated patients, 123 [97.6%; 95% confidence interval (CI): 93.2-99.5)]
were castrated 4 weeks after the first subcutaneous injection, and 115/119
patients (96.6%; 95% CI: 91.6-99.1) castrated at 4 weeks maintained castration at
26 weeks. Median prostate-specific antigen levels were reduced by 64.2 and 96.0%
at 4 and 26 weeks, respectively. The probability of maintaining a testosterone
level <20 ng/dl up to 26 weeks was 90.0% (95% CI: 85.0-95.0). The most frequently
occurring treatment-related adverse events were typical of gonadotropin-releasing
hormone agonist treatment (hot flushes, increased weight, erectile dysfunction
and hyperhidrosis). CONCLUSIONS: This study demonstrates that triptorelin pamoate
11.25 mg administered by the subcutaneous route every 3 months is as efficacious
and well tolerated as administration via the intramuscular route in men with
locally advanced or metastatic prostate cancer.
