Open Label, Multicenter, Randomized, Controlled Study of IM or Oral Exemestane (Aromasin) in Postmenopausal Women - Full Text View

Purpose

The purpose of this study is to find out if the two different formulations of exemestane (Aromasin), oral and injectable, are equivalent in terms of pharmacodynamics and pharmacokinetics, i.e., if ultimately both formulations have the same efficacy in postmenopausal women with metastatic breast cancer who have failed previous antiestrogens therapy and are equally safe.

Further study details as provided by Pfizer:

Primary Outcome Measures:

To determine the pharmacodynamic equivalence at steady state of the IM formulation of exemestane with the oral formulation in terms of plasma estrone sulphate inhibitory effect in postmenopausal women with advanced breast cancer.

Secondary Outcome Measures:

to characterize the pharmacodynamic profile of the two formulations in terms of estrogens, androgens, and sec hormone binding globulin
to characterize the pharmacokinetics of exemestane and 17 hydroexemestane after administration of the two formulations
to evaluate the relationships between pharmakokinetics and pharmacodynamics after intramuscular and oral administration of exemestane
to evaluate the effcacy (as tumor response)
to evaluate the incidence and severity of systemic toxicities and of the local tolerability of the injectable formulation
to evaluate the effect on serum bone turnover markers
