Fragile X syndrome (FXS) is a genetic disorder leading to various developmental problems ranging from learning disabilities to cognitive impairment. FXS is caused by mutation of the fragile X mental retardation 1 (FMR1) gene, which usually makes a protein known as fragile X mental retardation protein (FMRP). FMRP is required for normal brain development, and individuals with FXS do not make this protein. Individuals who have other fragile X-associated disorders (FXTAS) have mutations in their FMR1 gene, but they generally make some FMRP
Based on cohorts of children with special educational needs, the prevalence of fragile X syndrome (FXS) is estimated to be 1 in 4,000 in males, and 1 in 8,000 in females.
The largest proportion of industry-sponsored drugs in active clinical development for FXS are in Phase II. Therapies in active clinical development for FXS focus on targets such as cannabinoid-1/cannabinoid-2 receptor, phosphodiesterase 4, GABA receptors, GABA-A receptor, insulin-like growth factor-1 receptor, GABA-B receptor, NMDA glutamate receptor, and potassium channels. The majority of these pipeline drugs are administered via the oral route.
The overall likelihood of approval of a Phase I neurodevelopmental disorders asset is 2.9%, and the average probability a drug advances from Phase III is 20%. Drugs, on average, take 12.6 years from Phase I to approval, compared to 10.1 years in the overall neurology space.
The distribution of clinical trials across Phase I–IV indicates that the majority of trials for FXS have been in the early and midphases of development, with 82% of trials in Phase I–II, and only 18% in Phase III–IV.
The US has a substantial lead in the number of FXS clinical trials globally. France leads the major European markets, while Israel has the top spot in Asia.
Clinical trial activity in the FXS space is dominated by completed trials. Roche has the highest number of completed clinical trials for FXS, with ten trials.
Novartis and Roche lead industry sponsors with highest overall number of clinical trials for FXS, followed by Seaside Therapeutics.
