Clinical Studies

 

1-MONTH ADMINISTRATION

In a single, 18-year study, 1-month LUPRON DEPOT-PED demonstrated sustained, reversible suppression with follow-up data through adulthood1-3

Study Design for LUPRON DEPOT-PED 1-Month Administration

The 1-month LUPRON DEPOT-PED study was a prospective, multicenter, longitudinal study from 1991 to 2009 divided into 2 key phases: The open-label treatment period and the long-term, post-treatment follow-up period.2

Primary endpoint:2,3

Suppression of clinical sexual characteristics

Secondary endpoints:4

Gonadotropin concentrations; Sex hormone concentrations; Predicted mature height based on bone age; Ratio of bone age to chronological age; Growth rate

 

Results for LUPRON DEPOT-PED 1-Month Administration

Suppression of clinical sexual characteristics, based on Tanner staging.

    During 5 Years of Treatment

  • 66.7% to 90.6% of females had suppression of breast development1
  • 60% to 100% of males had suppression of genitalia development1

    At 6 Months Post-treatment

  • In females (n=35), increase in breast development was 66.7%3
  • 4 of 5 males showed Tanner genital stage advancement by Month 63

 

Secondary Endpoint Results for LUPRON DEPOT-PED 1-Month Administration

1-month LUPRON DEPOT-PED provided sustained suppression of mean peak LH, with hormone levels usually restored within 6 months of stopping treatment1

Mean Peak LHa Was Suppressed Throughout Treatment and Recovered After Therapy

were suppressed to prepubertal levels during the first 5 years of treatment1

 

Long-term study showed that growth and bone maturation normalized in patients treated with 1-month LUPRON DEPOT-PED2

Mean growth rate was 10.6 cm/year at baseline2

 

Through year 5, growth rate ranged from 3.4 to 5.6 cm/year1

 

Bone maturation was delayed with therapy. Mean ratio of bone age to chronological age decreased from 1.5 at baseline to 1.1 by end of treatment1

 

Those patients observed
until they reached adult height had a mean increase in final adult height over predicted adult height, with a mean height standard deviation score of –0.21

Girls resumed reproductive development following treatment with 1-month LUPRON DEPOT-PED1

Mean time to menses was ~1.5 years1            |            Mean age was 12.9 years1


Safety Considerations1

During the early phase of therapy, gonadotropins and sex steroids rise above baseline because of the initial stimulatory effect of the drug. An increase in clinical signs and symptoms of puberty may be observed.

Psychiatric events have been reported in patients taking GnRH agonists, including LUPRON DEPOT‑PED. Events include emotional lability, such as crying, irritability, impatience, anger, and aggression. Monitor for development or worsening of psychiatric symptoms during treatment.

 

3-Month Administration

Sustained suppression with 3-month administration of LUPRON DEPOT-PED1

Study Design for LUPRON DEPOT-PED 3-Month Administration

Randomized, open-label clinical trial to assess the safety and efficacy of LUPRON DEPOT-PED 11.25 and 30 mg for 3-month administration in 84 subjects (n=76 females, n=8 males) with CPP between 1 and 11 years of age1

  • Efficacy was measured as the suppression of peak stimulated LH to < 4.0 mIU/mL, assessed at Months 2, 3, and 61
  • Both treatment groups had equal numbers of naïve and previously treated patients1

3-month 30-mg dosing suppressed LH concentrations at Months 2, 3, and 61

 

Stimulated and basal gonadotropins were reduced to prepubertal levels in 95.2% of patients with CPP.1

Adverse Reactions

  • The most common adverse reactions with GnRH agonists, including LUPRON DEPOT-PED 7.5 mg, 11.25 mg, or 15 mg for 1-month administration and LUPRON DEPOT-PED 11.25 mg or 30 mg for 3-month administration, are injection site reactions/pain including abscess, general pain, headache, emotional lability and hot flushes/sweating.1

Open Label Extension Study

Open-Label Extension Study Provides Long-Term Data With 3-Month Dosing5

Study Design for LUPRON DEPOT-PED Extension Study

Phase 3, open-label, multicenter extension study

Objective: Assess the long-term safety of continued treatment with 11.25- and 30-mg 3-month LUPRON DEPOT-PED over 36 months of treatment in children with CPP.

  • Objective included the maintenance of LH suppression and the effects on pubertal symptoms, sex steroid levels, and bone age

Study population:

  • Included 65 female and 7 male subjects with CPP
    • Ranged from 2–11 years of age at the beginning of the pivotal 6-month study
  • Subjects had received 6 months of LUPRON DEPOT-PED at doses of 11.25 mg (n=34) or 30 mg (n=38) IM every 3 months during the pivotal study
    • Patients continued the same treatment in this 36-month extension study
  • All subjects had successfully completed the pivotal 6-month lead-in study with maintained LH suppression

Results for LUPRON DEPOT-PED 3-Month 30-mg Administration

Patients Completing and Discontinuing5

  • 24 subjects completed the 36-month treatment period
  • 48 subjects discontinued the study
    • -The most common resason for discontinuation of treatment was that the individual was considered ready for progress through physiologic puberty

 

Safety Considerations

  • LUPRON DEPOT-PED® is contraindicated in patients who are allergic to any of the product ingredients or in females who are or may become pregnant.
  • Increased clinical signs and symptoms of puberty may occur during the early phase of drug therapy.
  • Psychiatric events have been reported in patients taking GnRH agonists, including LUPRON DEPOT-PED. Events include emotional lability, such as crying, irritability, impatience, anger, and aggression.
  • Monitor for development or worsening of psychiatric symptoms.
  • Convulsions have been observed in patients taking GnRH agonists, including LUPRON DEPOT-PED, with or without a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and in patients on concomitant medications that have been associated with convulsions.
  • Monitor response and continued adequate suppression following initiation of therapy, dosing change, or as judged clinically appropriate.
