IMProving Executive Function Study
Multi-Modal Imaging of Psychostimulant Effects on Executive Function Post-RRSO
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.

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.

Phase 4
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
  • Cognitive Impairment
  • RRSO
  • 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
  • Drug: Placebo oral capsule
    The placebo capsule will be filled with microcellulose.
    Other Name: sugar pill
  • 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.
    Intervention: Drug: Lisdexamfetamine
  • 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.
    Intervention: Drug: Placebo oral capsule
