Effect of Metformin on Adrenal or Ovarian Androgen Production in Overweight Pubertal Girls With Androgen Excess

Effect of Metformin on Adrenal or Ovarian Androgen Production in Overweight Pubertal Girls With Androgen Excess (CBS005)

NCT01422746•University of Virginia

View on ClinicalTrials.gov

Summary

This study will test whether metformin administration can ameliorate androgen (male hormone) overproduction in overweight pubertal girls with androgen excess. The investigators hypothesize that improvement in insulin sensitivity by 12 weeks of metformin administration will improve androgen levels after adrenal stimulation testing with adrenocorticotropic hormone (ACTH) or ovarian stimulation testing with recombinant human chorionic gonadotropin (rhCG).

Eligibility

Age

7 - 18 years

Sex

FEMALE

Healthy Volunteers

Inclusion Criteria

•Overweight(\>85th BMI%) females
•Early to late puberty (expected age range 7-18)
•Hyperandrogenemic (free testosterone greater than 2.5 standard deviations above the mean for normal control subjects of the same Tanner Stage)
•Screening labs within age-appropriate normal range, with the exception of a mildly low hematocrit (see below) and the hormonal abnormalities inherent in obesity which could include mildly elevated luteinizing hormone (LH), lipids, testosterone, prolactin, DHEAS, E2, glucose, and insulin; and decreased follicle-stimulating hormone (FSH) and/or sex hormone-binding globulin (SHBG)

Exclusion Criteria

•Age \< 7 or \> 18 y
•Inability to comprehend what will be done during the study or why it will be done
•BMI-for-age \< 5th percentile
•Positive pregnancy test or lactation.
•Abnormal laboratory studies will be confirmed by repeat testing to exclude laboratory error.
•Morning cortisol \< 3 µg/dL or history of Cushing syndrome or adrenal insufficiency
•History of congenital adrenal hyperplasia or 17-hydroxyprogesterone \> 300 ng/dL, which suggests the possibility of congenital adrenal hyperplasia (if postmenarcheal, the 17-hydroxyprogesterone will be collected during the follicular phase, or ≥ 40 days since last menses if oligomenorrheic). NOTE: If a 17-hydroxyprogesterone \>300 mg/dL is confirmed on repeat testing, an ACTH-stimulated 17-hydroxyprogesterone \<1000 ng/dL will be required for study participation.
•Total testosterone \> 150 ng/dL, which suggests the possibility of a virilizing neoplasm
•DHEAS greater than the upper limit of age-appropriate normal range (mild elevations may be seen in polycystic ovary syndrome (PCOS) and adolescent hyperandrogenemia (HA), and elevations \< 1.5 times the age-appropriate upper limit of normal will be accepted in these groups)
•Virilization
