The primary objective of this study is to compare the pharmacokinetic and pharmacodynamic effect between two preparations of somatropin (T and C) after a single administration of 5 mg in healthy subjects by altering serum somatropin pharmacokinetic parameters (AUC0-24h, AUC0-inf, Cmax, Tmax and T1 / 2) and pharmacodynamic (measurement of serum levels of IGF-1 presented by the concentration-time profile, AUC 0-24h and AUC0-inf.).

Primary Outcome Measures:
  • The primary efficacy endpoint will be based in the investigation of pharmacokinetics and pharmacodynamics of somatropin in research subjects after administration of single dose, sc, of the drug. [ Time Frame: PK: 0, 1, 2, 3, 3:30, 4, 4:30, 5, 6, 9, 12, 15, 18, 24 hours. PD: 0, 6, 12, 24 hours. ]

    Pharmacokinetic evaluation will be based on data obtained from the average dosage of somatropin plasma. Thus, the time of collection facilities provide the pharmacokinetic parameters AUC0-24h, AUC0-inf, Cmax, Tmax and T1 / 2, which will be compared between the two formulations.

    The quantification of serum somatropin kit will be performed by ELISA validated using human serum as a biological matrix.

    The evaluation of the pharmacodynamics will be performed by quantifying serum levels of IGF-1 presented by the concentration-time profile, AUC 0-24h and AUC0-inf.

Secondary Outcome Measures:
  • After administration of the drug will be evaluated for safety and tolerability of the drug through the presence of hematoma, pain, itching and local redness, as well as the incidence of adverse events directly related to somatropin. [ Time Frame: 15 weeks ]

Estimated Enrollment: 32
Study Start Date: March 2013
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Somatropin Test
Somatropin of Blausiegel Indústria e Comércio Ltda.
Drug: Somatropin
single subcutaneous dose of 5mg
Active Comparator: Saizen
Somatropin of Merck Serono
