Yamo announced that the Food and Drug Administration (FDA) has granted Fast Track designation to L1-79, a new drug candidate intended to mitigate the socialization and communication symptoms in patients with autism spectrum disorder (ASD). There are currently no approved pharmacological treatments that address these core symptoms of ASD.

L1-79 is a tyrosine hydroxylase inhibitor that is believed to work by modulating the catecholaminergic pathways involved in ASD. Findings from a Phase 2 study showed that within days of initiating L1-79, patients experienced reductions in irritability, lethargy, hyperactivity, and anxiety, as well as improvements in speech, communication, socialization, and awareness of self and others. Although the 28-day study included a small sample size, positive trends in clinical benefit were observed, and the treatment was well tolerated in all patients.
