On January 5, 2026, the FDA approved ScinoPharm Taiwan’s glatiramer acetate (GA) injection as a treatment for relapsing multiple sclerosis (MS), making it the first complex injectable generic approval for this therapy.1 That guidance allows waiving traditional clinical bioequivalence trials if the generic demonstrates tight structural and compositional matching, as well as in vitro and in vivo functional similarity. On January 6, 2026, the FDA granted breakthrough therapy designation to Alkermes’ alixorexton, an investigational oral, selective orexin 2 receptor agonist, for the treatment of narcolepsy type 1 (NT1), using positive phase 1 and phase 2 data, including the phase 2 VIBRANCE-1 trial (NCT06358950), to support the decision. Months after the FDA issued a complete response letter (CRL) to the new drug application (NDA) for Sentynl Therapeutics’ copper histidinate, on January 12, 2026, the agency approved the agent as the first treatment for pediatric patients with Menkes disease, a rare genetic neurodegenerative disorder.3 Marketed as Zycubo, the therapy is a subcutaneous copper replacement treatment that delivers copper in a form designed to bypass impaired intestinal absorption and support systemic utilization of the mineral. "This milestone represents the culmination of decades of research into better understanding and ultimately finding an effective treatment for Menkes disease," Stephen Kaler, MD, a clinical genetics and genomics specialist, and professor of pediatrics at the Columbia University Medical Center, said in a statement.3 "Increased awareness of Menkes disease and rapid testing upon suspicion are critical, as beginning copper histidinate therapy in affected neonates has been shown to reduce symptoms and prolong life."
