Decapeptyl® SR has efficacy you can trust

Maintain castrate testosterone levels with Decapeptyl® SR 6-monthly (every 24 weeks).1

Decapeptyl® SR 6-monthly data show that men with locally advanced or metastatic prostate cancer can achieve and maintain castrate testosterone levels (≤50 ng/dL) versus their baseline values.1

Key findings

Almost all (97.5%, n=120) patients achieved castrate testosterone levels by day 29.1

Moreover, 93% (n=115) maintained castrate testosterone levels month 2 to 12.1

The median relative decrease in serum PSA vs baseline was 97% after 6 months and 96% after 12 months.1

Study information1

Design: A Phase 3, multicentre, open-label, non-comparative study conducted in South Africa.

Aim: To evaluate the efficacy, pharmacokinetics and safety of Decapeptyl® SR 6 monthly.

Primary endpoints: Proportion of patients achieving castrate serum testosterone levels (≤1.735 nmol/L or ≤50 ng/dL) by day 29 and the proportion maintaining castration at months 2–12.

Patients: 120 men with advanced prostate cancer with a life expectancy of at least 18 months and a baseline serum testosterone level of more than 5 nmol/L.

Achieve durable results with Decapeptyl® SR

Clinical data have shown that Decapeptyl® SR formulations maintained castrate testosterone levels versus baseline in patients with advanced prostate cancer patients over a 12-month period.2

Key finding

The majority (95-99%) of patients achieved and maintained castrate testosterone levels (≤50 ng/dL) for 12 months.

Study information2

Design: A pooled, retrospective analysis of data from 920 men with prostate cancer who had been enrolled in nine prospective studies conducted in Europe and South Africa and had used testosterone serum concentrations as the primary endpoint.

Aim: To assess the ability of 1-, 3- and 6-monthly Decapeptyl® SR formulations to suppress serum testosterone concentrations beyond current standards (<50 ng/dl).

Primary endpoints: Serum testosterone concentrations under treatment and success rates overall and per formulation, based on a testosterone target threshold of 20 ng/dl.

Patients: Aged 42–96 years had to be eligible for ADT and to be either naïve to hormonal treatment or have undergone an appropriate washout prior to enrolment.

Alleviate your patients’ lower urinary tract symptoms and improve QoL3

Decapeptyl® SR (1- and 3-monthly) had been shown to improve lower urinary tract symptoms (LUTS) versus baseline in patients with locally advanced or metastatic prostate cancer. 3 As a result, an improvement in quality of life (QoL) has been observed.

Study information3

Design: Prospective, non-interventional, multicentre studies of lower urinary tract symptoms (LUTS) conducted in Algeria, Belgium, China, Hungary, Romania and South Korea.

Aim: To evaluate the effect of Decapeptyl® SR on lower urinary tract symptoms (LUTS) in patients with advanced prostate cancer.

Primary endpoint: The primary efficacy endpoint was the proportion of patients with moderate or severe LUTS after 48 weeks as assessed by the International prostate symptom score (IPSS). Secondary endpoints included the distribution of IPSS categories, total IPSS and prostate-specific antigen (PSA) levels at baseline, 24 and 48 weeks.

Decapeptyl® SR 3mg showed similar efficacy to goserelin and leuprorelin4,6

Decapeptyl® SR vs goserelin

Decapeptyl® SR 3 mg reduced prostate volume to a similar extent as goserelin 3.6 mg within a similar time frame in patients with localised prostate cancer receiving neoadjuvant LHRHa therapy prior to radiotherapy.4

*Boxes depict median values as a horizontal line plus 95% CIs, while range (minimum and maximum) values are represented by whiskers. 12 weeks after the first LHRHa injection, prostate volume decreased by a mean (±SD) of 32.5% ± 20.9 and 36.8% ±18.4 with Decapeptyl®SR and goserelin, respectively, with no significant differences between groups (p=0.36).

Adapted from Bahl A et al., 2016

Study information4

Design: Single-blind, single-centre, randomised controlled trial.

Aim: To determine the effect of Decapeptyl® SR 3mg (every 12 weeks) on the reduction of prostate volume pre-radiotherapy compared with standard therapy.

Primary endpoint: The primary endpoint was the reduction in prostate volume as measured by transrectal ultrasound (TRUS). A secondary endpoint was the proportion of patients achieving castrate serum testosterone levels (50 ng/dl) during the 12 weeks from first LHRHa injection.

Patients: A total of 70 patients with localised prostate cancer who were candidates for and had selected radical radiotherapy.

Treatment: Decapeptyl® SR 3mg (n=36) or goserelin 3.6mg (n=34) every 4 weeks for 12 weeks. Patients also received associated antiandrogen treatment with bicalutamide for 28 days and underwent radical radiotherapy after completion of LHRHa treatment.

Study information6

Design: Open, randomised comparison. Laboratory evaluations included plasma prostate-specific antigen and testosterone level assays.

Aims: To compare the efficacy of Decapeptyl® SR (1-monthly, every 28 days) and leuprorelin in men with prostate cancer and to assess the pattern of plasma testosterone following each LHRHa injection.

Primary endpoint: Plasma prostate-specific antigen (PSA) and testosterone were measured before, 24 and 72 h after each injection of LHRHa.

Patients: 67 patients who were previously untreated and not suitable for surgery and had histologically proven prostate carcinoma were randomised.

Treatment: Decapeptyl® SR 3mg or leuprorelin every 4 weeks for 3 months. All patients in the study received 250 mg flutamide or 100 mg nilutamide three times a day for 1 month. In 23 patients, this treatment was prolonged throughout the study. The first injection of LHRHa was performed 1 week after starting the treatment with pure antiandrogens.

Decapeptyl® SR side effects

As seen with other LHRHa therapies or after surgical castration, the most commonly observed adverse events related to Decapeptyl® SR treatment were due to its expected pharmacological effects (lowering of serum testosterone to castration levels).

In the treatment of prostate cancer, Decapeptyl® SR is generally well tolerated with the side effects of Decapeptyl® SR 6-monthly being consistent with the 1- and 3-monthly formulations.7

The DESERVE Study: Effects of Initiating or Switching to a Six-Monthly (every 24weeks) Triptorelin Formulation on Prostate Cancer Patient-Healthcare Interactions and Hospital Resource Use: Decapeptyl Service Evaluation

The primary endpoint of the DESERVE study was to observe the reduction in service interactions for users switching to the 6-monthly LHRHa injection frequency from the 1 and 3-month injection frequencies. A secondary endpoint additionally identified a potential cost reduction impact in the switch. 5

The results showed that switching to Decapeptyl® SR 6-monthly had the potential to save NHS resources and costs versus 1- and 3-monthly LHRHa injection frequencies.5

The cost reductions seen were based upon the decrease in the total number of patient–healthcare interactions (41.5%; p<0.0001, or 417 interactions pre-switch vs. 244 interactions post-switch).5

PSA control with switch to Decapeptyl® SR 6-monthly5

Decapeptyl® SR 6-monthly maintained control of PSA in patients* who switched from 1- and 3-monthly LHRHa injection frequencies.5

Decapeptyl® SR 6-monthly also reduced PSA levels in newly initiated patients versus baseline. 5

* In this group of switch patients with stable and controlled serum PSA levels, 6-monthly PSA testing is considered as appropriate and effective for disease monitoring as 3-monthly testing. Switch patients: PSA 0.35, 0.18 and 0.24 ng/ml at baseline, 6 months and 12 months respectively. Newly initiated patients: PSA 23.5, 0.84 and 1.3 ng/ml at baseline, 6 months and 12 months respectively
