Study Description
Brief Summary:
This is a double-blind, placebo-controlled, crossover study testing whether Vyvanse (lisdexamfetamine; LDX) improves executive functioning (EF) in 100 postmenopausal women who report onset of EF difficulties after oophorectomy. This study involves magnetic resonance imaging (MRI) to see how LDX affects brain chemistry while undergoing two 6-week trials of the study drug and placebo capsules.

Condition or disease Intervention/treatment Phase
Cognitive Impairment RRSO Drug: Lisdexamfetamine Drug: Placebo oral capsule Phase 4

Detailed Description:

Following a medically induced menopause, many women report difficulty in remembering things, focusing and concentrating. The purpose of this study is to examine the effects of a stimulant medication called Vyvanse® (lisdexamfetamine; LDX) on executive functioning, such as attention, processing, organization, and memory, in women who are experiencing executive functioning difficulties after having undergone a risk-reducing bilateral salpingo-oophorectomy (RRSO). This study involves magnetic resonance imaging (MRI) to see how LDX affects brain chemistry while undergoing two 6-week trials of the study drug and placebo capsules.

Individuals wishing to participate in this study are medically healthy women between the ages of 35-55 years old who have undergone a risk-reducing bilateral salpingo-oophorectomy (RRSO) within the previous 15 years. Participants must have been premenopausal before undergoing RRSO (meaning they were having regular periods). They also must not have undergone radiation or chemotherapy at any point before or after your RRSO.

Furthermore, participants must not suffer from a mental illness, including Attention Deficit Hyperactivity Disorder (ADHD), and must not have a recent history of drug abuse. Additionally, participants must also be right-handed, not suffer from a fear of small, enclosed spaces (claustrophobia), and not have any implanted medical devices such as a pacemaker, orthodontic braces, or shrapnel. They must not have a history of seizures, uncontrolled hypertension or known renal impairment.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Lisdexamfetamine
Participants will have a 50% chance of receiving the active study medication. They will begin at 20 mg/d and will increase up to 60 mg/d after 4 weeks, if well tolerated. Total time on the study drug is up to 6 weeks.
Drug: Lisdexamfetamine
Stimulant medications are used to reduce interruptive behavior, fidgeting, and other hyperactive symptoms, as well as help a person finish tasks and improve his or her relationships for adults who have ADHD. Please note that the FDA has not approved the use of Vyvanse® for the treatment of memory and concentration difficulties related to medically induced menopause.
Other Name: Vyvanse
Placebo Comparator: Placebo
Participants will have a 50% chance of receiving the placebo for this study. They will begin with 1 sugar pill and will increase up to 3 pills after 4 weeks. Maximum time for taking the placebo is 6 weeks.
Drug: Placebo oral capsule
The placebo capsule will be filled with microcellulose.
Other Name: sugar pill


Outcome Measures

Primary Outcome Measures :
  1. Brown Attention Deficit Disorder Scale (BADDS) Score [ Time Frame: 6 weeks ]
    To subjectively determine whether treatment with LDX improves self-reported executive function (EF) via the BADDS


Secondary Outcome Measures :
  1. Brain activation [ Time Frame: 6 weeks ]
    To objectively determine the impact of LDX on executive system activation during a working memory task via proton magnetic resonance spectroscopy (1H-MRS) and functional magnetic resonance imaging (fMRI)
