Clomiphene Citrate for Treatment of Acromegaly

Status Completed

Clinical Trial Summary

To assess the impact of clomiphene citrate on serum insulin like growth factor 1 and testosterone levels in male acromegalic patients not controlled by surgery, radiotherapy and/or medical treatments (somatostatin analogues, dopamine agonists and/or growth hormone receptor antagonist)

Clinical Trial Description

Acromegaly, a disease caused by a growth hormone secreting pituitary adenoma, results in reduced life span. Despite the many modalities available to treat this disease,as surgery, medical treatment and radiotherapy, uncontrolled disease persists in a significant portion of patients

Oral estrogens, alone or in combination with somatostatin receptor analogues, have been shown to control acromegaly in women. Selective estrogen receptor modulators (SERMs) resulted in similar effects in both genders. Clomiphene citrate, a SERM that increases luteinizing hormone and follicle stimulating hormone secretion, improves hypogonadism and fertility outcomes.

The aim of this study is to assess the impact of clomiphene citrate on serum insulin like growth factor 1 and testosterone levels in male acromegalic patients not controlled by surgery, radiotherapy and/or medical treatment.

In this prospective, open label, single center trial, sixteen male patients were studied. Clomiphene citrate (50 mg/day) was added to previous medical treatment for 3 months and hormonal assessment was performed prior to and during the intervention. Hormones included: growth hormone, insulin like growth factor, total testosterone, follicle stimulating hormone, luteinizing hormone and prostate-specific antigen. ;
