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.
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.
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.
Chief Business Officer David McNinch told BioWorld that South San Francisco-based Encoded Therapeutics Inc.’s $135 million from an oversubscribed series D financing follows by about a year the hefty series C round that “helped us get the [lead gene therapy] program poised to its current stage, which is IND-enabling studies.” The asset, ETX-101 for SCN1A-positive Dravet syndrome (DS), is expected to enter human trials next year.
Stoke Therapeutics Inc. is marching ahead in the second half of this year with its phase I/IIa study with STK-001 in Dravet syndrome (DS), one of the more abysmal forms of epilepsy, although the FDA has temporarily hobbled part B of the test, pending preclinical data that will more fully characterize the safety profile of the antisense oligonucleotide (ASO).
