The efficacy and safety
of TRIPTODUR were
demonstrated in a multicenter
phase 3 study1,2
aMeasurement of serum LH, FSH, estradiol (girls), and testosterone (boys) levels collected at screening and at Months 1 (Day 29), 2 (Day 57), 3 (Day 85), 6 (Day 169), 9 (Day 253), and 12 (Day 337).1,2 LH and FSH were assessed both before and 30 minutes after stimulation with commercial leuprolide acetate 20 μg/kg subcutaneous injectable solution 1 mg/0.2 mL.1,2
bTransabdominal ultrasound was performed in girls; bone age was assessed by x-ray of the left hand and wrist. Collected during screening period, Month 6, and Month 12.2 Presence of unstable intracranial tumors at screening was excluded by MRI or CT scans of the brain, unless they had been performed within 3 months prior to treatment initiation.

98% of children achieved LH suppression with TRIPTODUR at Month 121
Three patients presented with nonsuppressed LH levels at Month 6.2
Note: 95% of children (n/N=42/44) achieved prepubertal LH levelsa at Months 2, 3, and 9.

IMPORTANT SAFETY INFORMATION
TRIPTODUR is contraindicated in:
Warnings and Precautions
Initial Rise of Gonadotropins and Sex Steroid Levels - During the early phase of therapy, gonadotropins and sex steroids rise above baseline because of the initial stimulatory effect of the drug. Therefore, a transient increase in clinical signs and symptoms of puberty, including vaginal bleeding, may be observed during the first weeks of therapy or after subsequent doses.
Psychiatric Events - Psychiatric events have been reported in patients taking GnRH agonists. Postmarketing reports with this class of drugs include symptoms of emotional lability, such as crying, irritability, impatience, anger, and aggression. Monitor for development or worsening of psychiatric symptoms during treatment with TRIPTODUR.
Convulsions - Postmarketing reports of convulsions have been observed in patients receiving GnRH agonists, including triptorelin. These included patients with a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and patients on concomitant medications that have been associated with convulsions such as bupropion and SSRIs. Convulsions have also been reported in patients in the absence of any of the conditions mentioned above.
In clinical trials for TRIPTODUR, the most common adverse reactions (≥4.5%) are injection site reactions, menstrual (vaginal) bleeding, hot flush, headache, cough, and infections (bronchitis, gastroenteritis, influenza, nasopharyngitis, otitis externa, pharyngitis, sinusitis, and upper respiratory tract infection).
You are encouraged to report side effects of prescription drugs to Arbor Pharmaceuticals, LLC Medical Information at 1-866-516-4950 or to the FDA at www.fda.gov/medwatch or call 1-800-FDA-1088.
