Marinus Launches Ztalmy for Rare Seizure Disorder


Orsini Specialty Pharmacy has been chosen as the exclusive pharmacy provider of Ztalmy.

Marinus Pharmaceuticals has launched Ztalmy (ganaxolone) oral suspension, which was approved in March 2022 to treat patients two years of age and older, usually girls, with seizures associated with cyclin-dependent kinase-like 5 deficiency disorder (CDD), a rare, genetic form of epilepsy.

CDD is a serious and rare genetic disorder characterized by early‑onset, difficult‑to‑control seizures and severe neuro‑developmental impairment. It’s caused by a mutation of the cyclin-dependent kinase-like 5 (CDKL5) gene, located on the X chromosome. The gene produces a protein that is important for normal brain development and function. Many children diagnosed with CDD also experience scoliosis, visual impairment, sensory problems, gastrointestinal difficulties, and sleeping disorders.

Ztalmy, a neuroactive steroid that acts as a positive allosteric modulator of the GABAA receptor, is the first FDA-approved treatment specifically for CDD. Data from the phase 3 Marigold double-blind placebo-controlled trial of 101 patients with CDD, published in The Lancet Neurology in which ZTALMY significantly reduced the frequency of monthly major motor seizures by a median of 30.7% compared with 6.9% for placebo.
