Description
Sources: https://www.fraxa.org/novartis-discontinues-development-mavoglurant-afq056-fragile-x-syndrome/ | https://clinicaltrials.gov/ct2/show/NCT03242928 | https://www.ncbi.nlm.nih.gov/pubmed/25316499

Mavoglurant (AFQ056) was developed as a new metabotropic glutamate receptor 5 (mGluR5) antagonist. The efficacy of mavoglurant in humans has been assessed in L-dopa induced dyskinesia in Parkinson's disease and Fragile X syndrome in proof of principle clinical studies. However, Novartis had announced that the company would be discontinuing its development program in Fragile X following negative results in a large international clinical trial in adults, and more recently in a trial in adolescents. In both placebo-controlled trials, patients taking mavoglurant did not show improvement over placebo in any outcome measures. In patients with L-Dopa-induced dyskinesias studies failed to meet the primary objective of demonstrating improvement of dyskinesia. Mavoglurant was also investigated in phase II clinical trials to reduce chorea in Huntington's disease, but the target result was not achieved. Currently Novartis is conducting a phase II clinical trial to demonstrate whether or not this drug can benificially reduce cocaine use in Cocaine Use Disorder.

Sample Use Guides

In Vivo Use Guide

l-Dopa-induced dyskinesias: mavoglurant (AFQ056) was up-titrated over two weeks from 25 mg twice daily (bid) to 100 mg bid (L-dopa kept stable), followed by three weeks during which the daily L-dopa dosage was increased by up to 300 mg/day. The study was a randomized, placebo- and active-controlled, 4-period, crossover, conduct of thorough QTc (TQT) study composed of 2 sequential phases. In the pilot phase, the safety and tolerability profile of 10-minute infusions of 25, 37.5, and 50 mg of mavoglurant was assessed in 36 healthy individuals. In the TQT phase, individuals received in random sequence single intravenous doses of mavoglurant (25 and 50 mg) and placebo and an oral dose of moxifloxacin (400 mg).

Route of Administration: Other

In Vitro Use Guide

AFQ056/mavoglurant was identified by chemical derivatization of a lead compound discovered in a HTS campaign. In vitro, AFQ056/mavoglurant had an IC50 of 30 nM in a functional assay with human mGluR5 and was selective over the other mGluR subtypes, iGluRs and a panel of 238 CNS relevant receptors, transporter or enzymes.
