LDX for the Treatment of Cognitive Functioning Issues in Women Post-Oophorectomy (LDX)

September 15, 2017 updated by: University of Pennsylvania

LDX in the Treatment of Executive Function Difficulties in Women After Oophorectomy

This is a double-blind, placebo-controlled, study testing whether LDX improves cognitive function and EF in 20 postmenopausal women who report onset of cognitive difficulties after oophorectomy (with or without subsequent chemo/adjunctive therapy). Brain imaging is included at critical time points to obtain objective data regarding effects of LDX as well as potential predictors of resilience in the face of oophorectomy.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants will be asked to undergo three brain-imaging scans throughout the course of the study. Once they are deemed eligible for participation based on two assessment visits, they will be scheduled for their baseline test day. On this they, they will be asked to under a series of cognitive tests following by a brain-imaging scan. They will then take the first dose of either the LDX or placebo, wait for 3 hours and then undergo another brain-imaging scan to assess acute changes to memory/cognition due to the study drug. They will then come in for three 30-minute check-in visits during weeks 2, 4 and 6 on the study drug. They will be asked to undergo a final scan and series of cognitive tasks during weeks 8-10 on the study drug. They will then be discharged from active study participation. All participants, regardless of randomization, will be offered a consultation with the study MD and optional prescription for 4-weeks of treatment with LDX.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
BADDS Score
Time Frame: 8-10 weeks
To determine whether treatment with LDX improves self-reported executive function (EF) as measured with the BADDS
8-10 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Brain Activation
Time Frame: 8-10 weeks
To determine the impact of LDX on brain activation in the brain during a working memory task.
