Updated results from Stoke Therapeutics Inc.’s studies of antisense oligonucleotide STK-001 showed a reduced convulsion seizure frequency in those ages 2 to 18 with Dravet syndrome. The new data, which also showed improved cognition and behavior in participants, substantially boosted the company’s stock value and caused analysts to applaud.
Longboard Pharmaceuticals Inc.’s positive – and then some – phase Ib/IIa top-line data with 5-HT2C receptor superagonist bexicaserin (LP-352) in developmental and epileptic encephalopathies (DEEs) sparked Wall Street speculation about competitive odds as well as the shape of the firm’s upcoming phase III effort.
Stoke Therapeutics Inc.’s stock tumbled 32% after the company reported phase I/IIa data of its antisense oligonucleotide, STK-001, in Dravet syndrome, showing it reduced convulsive seizures in children most consistently at the highest dose, with benefits increasing as time progressed.
Iama Therapeutics srl and Psychogenics Inc. have entered into a new services agreement to identify the efficacy of novel drug candidates in preclinical animal models of Dravet syndrome.
Dravet syndrome is a type of congenital epilepsy caused by nonsense mutations in the SCN1A gene in about 20% of cases; SCN1A gene encodes the alpha subunit of the voltage-gated sodium channel Nav1.1. Spanish researchers and their collaborators have developed a novel murine model of Dravet syndrome; the model was developed by CRISPR/Cas9-generated A>T point mutation at nucleotide 1837 that converts Arg613 to a STOP codon, and which was introduced into exon 12 of the murine Scn1a gene using 129S1/SvImJ embryos.
As Wall Street waits to find out later this year whether Stoke Therapeutics Inc.’s positive results with a low, single dose of STK-001 for Dravet syndrome pans out in more extensive research, a number of players large and small are investigating candidates for the rare but dismal form of epilepsy.
Having rung the bell in phase II last summer, Ovid Therapeutics Inc. and Takeda Pharmaceutical Co. Ltd. signed a pact giving the latter global rights to develop and commercialize soticlestat, a first-in-class inhibitor of cholesterol 24-hydroxylase for the treatment of developmental and epileptic encephalopathies including Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS).

Questions about the price tag, the extent of diligence done on intellectual property, and the staying power of Epidiolex (cannabidiol) as well as the potential of other prospects in the acquiree’s pipeline bubbled up during the conference call related to Jazz Pharmaceuticals plc’s whopping takeover of GW Pharmaceuticals plc.
