Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

According to Dr. Erickson, AZD7325 is a drug that selectively boosts GABA neurotransmission in the brain. GABA is the primary neurochemical in the brain that blocks brain activation. GABA activity is in balance in the brain with Glutamate activity, which is the primary neurochemical that causes brain activation. In Fragile X, GABA activity is insufficient and glutamate activity is excessive, likely causing brain activity to be out of balance. AZD7325 attempts to correct parts of this imbalance by boosting the insufficient GABA activity in the brains of people with Fragile X

Trial and No Error: Better Outcomes for Clinical Trials in Fragile X Syndrome

Trial and No Error: Better Outcomes for Clinical Trials in Fragile X Syndrome
Johns Hopkins Researcher Christina Timmerman, PhD, Searches for a Less Subjective Method to Determine if a Drug is Working in Patients with Fragile X Syndrome Many parents of children with Fragile X syndrome were crushed when promising drug trials were unexpectedly stopped a few years ago because subjective behavior-based outcome measures did not justify continuing the trials. The strong feelings linger today. If all goes well with Christina Timmerman’s research, future drug trials may be able to continue with additional metrics for assessment, until there are advanced treatments or even a cure for Fragile X syndrome. This will be welcome news to parents. Timothy Gamache, graduate student, and Christina Timmerman, PhD “We hope a more quantitative outcome measure, such as the proposed microRNA biomarker, would allow for a less subjective method to determine if a drug is working or not,” said Dr. Timmerman, Postdoctoral Fellow, Lab of Mollie Meffert, DepartmentRead more

Double Down: Fragile X Clinical Trial Combines Two Available Drugs

Double Down: Fragile X Clinical Trial Combines Two Available Drugs
Jean-Francois Lepage, PhD, and Francois Corbin, MD, PhD, with MRI machine If all the science world’s a stage, Fragile X researchers are more than merely players. They are center stage. So believes Francois Corbin, MD, PhD, professor, Université de Sherbrooke, Canada, who directs the university’s Fragile X Clinic. Corbin, who has received more than $100,000 in FRAXA support since 2012, is leading a pilot randomized Phase II trial, exploring the tolerability and the synergistic effect of a combined therapy. They will combine minocycline, which is often used to treat acne, and lovastatin, which is used to lower cholesterol. Both drugs target specific alterations in the brain of Fragile X patients that would potentially have a combined powerful effect on their behavior. “To my knowledge, this is the first time we have a clinical trial with two different drugs combined to act on two different targets,” Corbin said. “The combined actionRead more

Social Behavior as an Outcome Measure for Fragile X Clinical Trials

Social Behavior as an Outcome Measure for Fragile X Clinical Trials

One of the features of the Fragile X mouse model which is relevant to the human Fragile X syndrome (and autism) is social behavior. Several tests show consistent social behavioral abnormalities in the Fragile X mouse model. With a $140,000 grant from FRAXA Research Foundation in 2012-2013, Dr. Willemsen at Erasmus University used social behavior tests to measure the effectiveness of several drug strategies.

Development of a Novel GABA-A Agonist in Fragile X Syndrome

Development of a Novel GABA-A Agonist in Fragile X Syndrome

Of the many genes known to be regulated by FMRP, the gamma-aminobutyric acid receptor A (GABA(A)), is gaining attention as a potential target for the treatment of FXS. Mounting evidence suggests decreased expression and functioning of GABA(A) is involved in the pathophysiology of FXS. Non-selective GABA(A) agonism in animal models of FXS has been associated with normalization of morphological features, GABA(A) expression, and behavior. However, the clinical use of these agents in Fragile X is associated with unwanted side-effects, such as sedation, dulling of cognition, and occasional paradoxical agitation, which limits their use. Given the limitations in available GABA(A)-based treatment of FXS, this group plans to investigate a novel selective GABA(A) agonist in a mouse model of FXS. This agent has the potential to relieve many symptoms of Fragile X without the unwanted side effects.
