Foresee Pharmaceuticals announced that the first patient has been dosed in the Casppian Phase 3 registration study. The Casppian Phase 3 study is an open-label, multicenter clinical trial to evaluate the efficacy, safety, and pharmacokinetics of leuprolide (FP-001) 42 mg-controlled release in patients with central (Gonadotropin- Dependent) precocious puberty (CPP). The study duration is 48 weeks.

The study's Primary endpoint is the percentage of patients with serum LH concentration < 4 mIU/mL 30 minutes following a GnRH agonist stimulation test at Week 24. Leuprolide (FP-001) 42 mg will be considered effective for the treatment of children with CPP if = 80% of patients exhibit LH suppression < 4 mIU/mL at Week 24. The Casppian study will also test key secondary endpoints like the changes in bone ages, growth rate, and physical signs of puberty assessed by Tanner stages from baseline to the end of the study at 48 weeks, which the FDA has accepted.

GnRH-dependent CPP is a condition that causes early sexual development in girls and boys, as their "hypothalamus - pituitary gland - gonadal axis" is activated prematurely, causing children to enter puberty prematurely, between 2 years and 9 years of age. CPP patients are at risk of having significantly short stature as adults in addition to social, psychological, and emotional issues, including lower self-esteem, stress, anxiety, and depression, which may negatively impact their quality of life. According to the NORD (National Organization for Rare Disorders) website, CPP occurs in 1 out of 5,000 to 10,000 children.

It is estimated that approximately 80% - 90% of CPP cases are idiopathic, especially in females, with a female-to-male ratio of around 20: 1.
