TRELSTAR CAN MINIMIZE AGONIST DEFICIENCY

Proven efficacy with the ability to achieve castration (≤ 50 ng/dL) and maintain T levels below 20 ng/dL.2

Proven Testosterone Suppression:
Trelstar lowered testosterone below castration levels (50 ng/dL).1, 2

  • 4 TRELSTAR escapes occurred within the first 2 months of therapy only
  • 11 Lupron® escapes occurred throughout the entire 9-month study period

Primary Endpoint Results:
Castration levels of serum testosterone (≤ 1.735 nmol/L; equivalent to 50 ng/dL) in patients treated with TRELSTAR 3.75 mg were achieved at Day 29 in 125 of 137 (91.2%) patients and at Day 57 in 97.7% of patients. Maintenance of castration levels of serum testosterone from Day 57 through Day 253 was found in 96.2% of patients treated with TRELSTAR 3.75 mg.

TESTOSTERONE ESCAPES THROUGH MONTH 9​ 2,6

†At day 253, n=119 for Trelstar and n=121 for Lupron®.

STUDY DESIGN

Based on a 9-month, multicenter, parallel-group, double-blind, randomized, controlled clinical trial comparing Trelstar® 3.75 mg to leuprolide acetate in patients with advanced (stage C/D) prostate cancer (N=284). Mean testosterone levels were calculated for months 2 to 9.

Proven Testosterone Suppression (Primary Endpoint)

  • Trelstar lowered testosterone below castration levels.*1,2
  • Achieved at Day 29 in 125 of 137 patients (91.2%) with 3.75 mg
  • Maintenance of castration levels of serum testosterone from Day 57 through Day 253 was found in 96.2% of patients treated with TRELSTAR 3.75 mg
ALL 3 TRELsTAR FORMULATIONS MAINTAINED CASTRATION LEVELS*

STUDY DESIGN

3.75 mg: Based on a 9-month, multicenter, parallel-group, double-blind, randomized, controlled clinical trial comparing TRELSTAR 3.75 mg to leuprolide acetate (7.5 mg) in patients with advanced (stage C/D) prostate cancer (N = 284). Mean testosterone levels were calculated for Months 2 to 9. The primary efficacy endpoints were both achievement of castration by Day 29 and maintenance of castration from Day 57 through Day 253.1,2

 

 

11.25 mg: In a study of similar design, patients received either TRELSTAR 11.25 mg (N = 174) every 12 weeks for a total of up to 3 doses (maximum treatment period of 253 days) or TRELSTAR 3.75 mg (N = 172) every 28 days for a total of up to 9 doses. The primary efficacy endpoints were both achievement of castration by Day 29 and maintenance of castration from Day 57 through Day 253.1

 

 

22.5 mg: In a non-comparative trial, patients received TRELSTAR 22.5 mg (N = 120) every 24 weeks for a total of 2 doses (maximum treatment period of 337 days). The primary efficacy endpoints included achievement of castration by Day 29 and maintenance of castration from Day 57 through Day 337.1

 

* (≤ 1.735 nmol/L; equivalent to 50 ng/dL)

† Maintenance of castration was calculated using a frequency distribution.

‡ Cumulative maintenance of castration was calculated using a survival analysis (Kaplan-Meier) technique.

Safety

3.75 mg: The most common adverse reactions (≥5%) during TRELSTAR 3.75 mg therapy included hot flushes, skeletal pain, impotence, and headache.

 

11.25 mg: The most common adverse reactions (≥5%) during TRELSTAR 11.25 mg therapy included hot flushes, skeletal pain, headache, edema in the legs, and leg pain.

 

22.5 mg: The most common adverse reactions (≥5%) during TRELSTAR 22.5 mg therapy included hot flushes, erectile dysfunction, and testicular atrophy.

Study Design

The 3.75 mg data are based on a 9-month, multicenter, parallel-group, blindly randomized, controlled clinical trial comparing Trelstar® mg to leuprolide acetate in patients with advanced (stage C/D) prostate cancer (N=284). Mean testosterone levels were calculated for months 2 to 9.

 

The 11.25 mg data are based on a 9-month, multicenter, parallel-group, blindly randomized, controlled clinical trial comparing Trelstar® 11.25 mg to Trelstar® 3.75 mg (active comparator) in patients with advanced (stage C/D) prostate cancer (N=284). Mean testosterone levels were calculated for months 2 to 9.

 

The 22.5 mg data are based on a 12-month, multicenter, open-label, non-comparative phase 3 clinical trial that evaluated the efficacy, pharmacokinetics, and safety of 2 injections of 6-month Trelstar® 22.5 mg formulation in patients with advanced prostate cancer. Mean testosterone levels were calculated for months 2 to 12.
