Ganaxolone is under clinical development by Marinus Pharmaceuticals and currently in Phase II for Lennox-Gastaut Syndrome. According to GlobalData, Phase II drugs for Lennox-Gastaut Syndrome have a 100% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Ganaxolone’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Ganaxolone overview

Ganaxolone (Ztalmy) is a synthetic analog of the neuroactive steroid allopregnanolone acts as anticonvulsant agent. It is formulated as suspension for oral route of administration, Ganaxolone is indicated treatment of seizures associated with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) in patients 2 years of age and older.

Ganaxolone nanoparticle formulation is under development for the treatment of seizures associated with CDKL5 deficiency disorder (CDD) (X-chromosome disorder), status epilepticus (SE), tuberous sclerosis complex. The drug candidate is administered orally (capsule and suspension) and intravenously. Ganaxolone (synthetic analog of allopregnanolone) acts by targeting gamma-aminobutyric acid type A (GABAA) receptors and cyclin-dependent kinase-like 5 (CDKL5.

It was also under development for the treatment of infantile spasm (West syndrome), adult partial-onset epileptic seizures, Angelman syndrome, smoking cessation, fragile-X syndrome, postpartum depression (PPD), Lennox Gastaut syndrome and female children with epilepsy caused by a mutation of the protocadherin 19 gene (PCDH19), and Dravert syndrome, treatment-resistant depression (TRD) and post-traumatic stress disorder.
