E2 and LDX for the Treatment of Cognitive Complaints After Oophorectomy

N/AWithdrawnNCT01986764

University of Pennsylvania

Overview

This project seeks to address cognitive disturbance, which is a frequent adverse sequelae of riskreducing bilateral salpingo-oophorectomy (RRSO) with or without post-procedure chemotherapy and adjunctive treatments. RRSO after completion of childbearing is recommended for prevention of ovarian and breast cancer in women with BRCA1/BRCA2 mutations and standard of care for women with some forms of hormone-responsive cancer. Knowledge regarding the impact of this procedure, with or without chemotherapy, and subsequent hypogonadism on brain health is less than adequate. Premenopausal women who undergo an acute surgical menopause are at greater risk for verbal memory decline and executive function (EF) complaints, but as of yet, we cannot predict who is going to experience these adverse sequelae, nor do we have targeted prevention or treatment strategies other than hormone therapy, which is not an option in many cases and not always effective. An idealized sample as women who are planning for a RRSO will undergo brain imaging and behavioral assessments pre- and post-surgery as well as pre-/post-treatment with E2 or the psychostimulant, lisdexamphetamine (LDX; Vyvanse®).

Outcomes

Primary Outcomes

BADDS Score

This study uses a double-blind, placebo-controlled, design. The primary subjective outcome variable is the BADDS score measured at the initial screening visit, and one week after oophorectomy and 12 weeks after randomization to E2, LDX or placebo post-oophorectomy. The primary, out-of-scan objective outcome will be performance on the HVLT, while the primary, in-scanner outcomes will be behavioral and brain activation measures during performance of the N-back task.

Time frame: 12 weeks

Secondary Outcomes

Cognitive Functioning

The secondary outcome variable studies changes in memory assessed using a battery of cognitive tasks.
