Clinical Pharmacology of p38 MAP Kinase Inhibitor, VX-745, in Mild Cognitive Impairment Due to Alzheimer's Disease (AD) or Mild AD

April 2, 2018 updated by: EIP Pharma Inc

A Randomized, Open-Label, Multiple Dose Clinical Pharmacology Study of Two Doses of a Selective p38 MAP Kinase Inhibitor, VX-745 in Patients With Mild Cognitive Impairment (MCI) Due to Alzheimer's Disease (AD) or With Mild AD

This study will assess the effects of VX-745 on markers of disease in the central nervous system of patients with MCI due to AD or with mild AD. The study will also evaluate the safety and tolerability of VX-745 in these patients during 6 weeks of dosing, as well as the plasma and cerebrospinal fluid concentrations of VX-745 during dosing.

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.

Ages Eligible for Study

60 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Percent Change From Baseline to End of Treatment in Cerebrospinal Fluid Levels of Cytokines
Time Frame: Baseline and Day 42 of dosing with VX-745
Cytokines: Of nine cytokines assessed, only CSF IL-8 quantifiable at all time points. And so, only IL-8 levels are being reported herein. The analysis was exploratory and no statistical analysis was performed.
Baseline and Day 42 of dosing with VX-745

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
Severe or Serious Adverse Events
Time Frame: At baseline and at each study visit during (days 1, 7, 14, 21, 28, 35 and 42) and after (day 51) dosing

At baseline and at each study visit during (days 1, 7, 14, 21, 28, 35 and 42) and after (day 51) dosing
Maximal CSF VX-745 Concentration
Time Frame: All samples with quantifiable CSF drug levels were included (n=12). Eight were obtained 3-hours post-dose, either on Day 1 (n=4) or Day 42 (n=4). 3 samples were at 6-hours post-dose on Day 42; and one was at 6-hours post-dose on Day 1.
Ratio fo CSF to plasma drug concentration at time matched time points. Samples taken
All samples with quantifiable CSF drug levels were included (n=12). Eight were obtained 3-hours post-dose, either on Day 1 (n=4) or Day 42 (n=4). 3 samples were at 6-hours post-dose on Day 42; and one was at 6-hours post-dose on Day 1.
