Drug Tolerance in MGluR5 Clinical Trials – Dr Patrick McCamphill 1:1 with FRAXA

May 21, 2021

We have long suspected that the clinical trials of mGluR5 blockers from Novartis and Roche failed because the drug triggered tolerance, losing effect over time. With a $90,000 grant from FRAXA, Dr. Patrick McCamphill, a Postdoctoral Fellow in the MIT lab of Dr. Mark Bear, is investigating. He does indeed find tolerance, and now he is looking for ways to overcome it.

Scientists Find a New Way to Reverse Symptoms of Fragile X

May 20, 2020

FRAXA Investigator and MIT Professor Mark Bear and his colleagues have identified a valuable new target for Fragile X therapeutics: GSK3 alpha. Several FRAXA research teams previously identified GSK3 beta as a treatment target for Fragile X. The catch is that, so far, GSK3 beta inhibitors have proven too toxic for regular use. Dr. Bear’s new discovery opens up the possibility of developing more selective compounds with less toxicity and fewer side effects. Interestingly, lithium inhibits both GSK3 versions – alpha and beta.

Pharmacological Tolerance in the Treatment of Fragile X Syndrome

May 9, 2018

FRAXA funded MIT work to probe tolerance to key Fragile X drugs, including mGluR5 inhibitors and arbaclofen, and to identify ways to sustain long-term treatment benefits.
