Search Existing Data Requests

The Knight ADRC has supported many investigators at Washington University and at other institutions over the years. We wish to avoid the situation where two investigators study the same research question to avoid duplication of effort and potential conflict. To determine if your topic has already been studied with our resources, please search our database. If you find that your topic or a related topic has been submitted, you may wish to contact the investigator to inquire about their findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID number (e.g. T1004), the full request has been submitted and is either approved, disapproved or in process. If an entry has no ID number, then it represents a submission that has not yet been reviewed. Search terms are applied across an entire requests application including variables not displayed below. A more specific, detailed search may yield better results depending upon your needs.

Investigator: Catherine Roe

Project Title: Amyloid Imaging and CSF biomarkers in predicting cognitive impairment up to 12 and 18 years later

Date: [153]

Request ID: D1605

Aim 1: To examine whether participants with sporadic AD and positive AD biomarkers can stay cognitively normal for up to 18 years

Aim 2: To identify factors that distinguish those who do and do not remain cognitively normal

Aim 3:

Investigator: Roy M Anderson

Project Title: Phase II and III trial simulators: Using mathematical, computational and statistical techniques to simulate trial design for new products in the treatment of Alzheimer�s disease

Date: [153]

Request ID: D1604

Aim 1: The overall aim is the development of a clinical trial simulator for use in the design of phase II and III clinical trials of novel therapies for the prevention or slowing of AD onset.

Aim 2: A mathematical model will be developed, initially an individual based Discrete-state Markov model. Depending on the data available, other types of mathematical model will be considered.

Aim 3: Parameters of the model will be estimated from real data, these, in addition to the transition probabilities, can be compared between groups, e.g. Sex, presence of APOε4 allele

Aim 4: In order to support model development, an exploratory data analysis will be performed to dissect the relationship between various biomarkers and clinical measures of progression in various data sets.

Date: [153]

Request ID: D1528

Aim 1: To analyze the temporal dynamics of PET-PIB and CSF biomarker data with non-parametric functional mixed-models.

Investigator: Sylvia Villeneuve

Project Title: Association between the proximity to the parental age of onset and amyloid burden in individuals at risk of sporadic Alzheimer’s disease

Date: [153]

Request ID: D1527

Aim 1: We aim to elucidate whether individual distance to parental age of disease onset can be a useful parameter to measure disease progression in individuals with a family history of sporadic Alzheimer’s disease (AD).

Aim 2: We are interested in better understanding the contribution of ApoE in moderating the associations detailed in aim 1.

Aim 3: Given that we have found results providing evidence to support our hypotheses regarding aim 1 and 2, we would like to try to replicate our findings in a separate cohort

Aim 4:
