Testosterone Suppression With 4-Month Dosing
LUPRON DEPOT 30 MG: MEAN SERUM TESTOSTERONE CONCENTRATION THROUGH WEEK 321,4,5
Primary Endpoint Results1,4
Castrate levels were achieved in 94% of patients by day 30 and in all patients by day 43. After falling to castrate range, mean testosterone levels remained within the castrate range throughout each dosing interval.
Safety Data for 4-Month Dosing
The 4-month formulation of LUPRON DEPOT 30 mg was utilized in clinical trials that studied the drug in 49 nonorchiectomized prostate cancer patients for 32 weeks or longer and in 24 orchiectomized prostate cancer patients for 20 weeks.1

Considerations for Testosterone Measurement
- Based on assays available 40 years ago, surgical castrate levels of testosterone were reported as <50 mg/dL6,7
- US FDA and American Urological Association (AUA) currently define medical castration as testosterone levels <50 ng/dL8,9
- Current testosterone assay techniques are more rapid and accurate6
- Surgical castrate level using current assays determined as median 15 ng/dL (95% Cl: 12-17 ng/dL)6
- <20 ng/dL is the recommended goal for ADT therapy by the European Association of Urology Guidelines (EAU) 2023 and Bethesda consensus 20117,10
- No robust clinical data have clearly established the value of achieving testosterone <20 ng/dL6,10
ADT=androgen deprivation therapy; FDA=Food and Drug Administration.
Post hoc analysis of combined 4- and 6-month data, including pooled data
In a combined post hoc analysis of 2 phase 3 open-label studies in patients with histologically confirmed prostate adenocarcinoma, serum testosterone levels were pooled at each common time point to determine the number and proportion of patients who had levels ≤20 ng/dL. Assays with similar testosterone sensitivity were used.11
Limitations
Post hoc analyses are not powered or tested to demonstrate statistically significant differences in treatment effect. Pooled data limitation: patients with histologically confirmed adenocarcinoma were evaluated. Cancer staging and other patient characteristics (eg, age, prior treatment) may have been different between studies. The relationship between testosterone values and clinical outcomes has not been established.
- In the pooled analysis, mean serum testosterone was suppressed to ≤20 ng/dL in 79% to 89% of patients from week 4 through week 2411
- In the 6-month formulation of LUPRON DEPOT, 94% of patients were suppressed ≤20 ng/dL at week 4811

LUPRON DEPOT 22.5 MG: MEAN SERUM TESTOSTERONE CONCENTRATION THROUGH WEEK 241,12,13
Primary Endpoint Results1,12
Castrate levels (≤50 ng/dL) of testosterone were achieved within 30 days of the initial injection in 95% (87/92) of patients in the 2 studies. After falling to castrate range, mean testosterone levels remained within the castrate range throughout each 12-week dosing interval.
