Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the current phase I study was to establish bioequivalence, safety, and tolerance of single 300 IU subcutaneous dose of follitropin alfa biosimilar (Primapur) in comparison to that of reference follitropin alfa preparation (Gonal-F) in healthy young female volunteers.

2. To determine the AUC0-t value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.
3. To determine the T½ value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.
4. To determine the Сmax value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.
5. To determine the Tmax value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.
6. To compare the obtained pharmacokinetic characteristics of Primapur and Gonal-F.
