Stoke Therapeutics (STOK) Up on Upbeat Dravet Syndrome Study Data

Read MoreHide Full Article

Stoke Therapeutics, Inc. (STOK - Free Report) reported encouraging new data from two phase I/IIa studies and two open-label extension (OLE) studies evaluating investigational candidate,STK-001, in children and adolescents aged two to 18 years with Dravet syndrome.

STK-001 is Stoke Therapeutics’ novel proprietary antisense oligonucleotide with the potential to become the first disease-modifying therapy to address the genetic cause of Dravet syndrome, rather than just treating the symptoms like currently available treatments.

Per the data readout from the studies, treatment with STK-001 demonstrated clinically meaningful effects, including substantial and durable reductions in convulsive seizure frequency and improvements in multiple measures of cognition and behavior that support the potential for disease modification.

These positive effects of treatment with STK-001 were observed in a highly refractory group of patients already taking the best available anti-seizure medicines. The candidate has also been overall well tolerated in the studies to date, with an acceptable safety profile.

Stoke Therapeutics also reported that the FDA has allowed the company to treat patients with three doses of STK-001 70mg followed by continued dosing at 45mg.

The company is currently gearing up to meet with regulatory agencies to discuss a registrational study that includes initial doses of STK-001 70mg followed by continued dosing at 45mg in Dravet syndrome patients, based on the regulatory update and positive data from the studies of the candidate. An update regarding the same is expected later in 2024.

Stoke Therapeutics’ stock rallied 58.3% on Mar 26 and continued to gain another 5% in the after-market hours as the investors cheered the encouraging regulatory and development update for STK-001. In the past year, shares of STOK have gained 28.1% against the industry’s 8.5% decline.

The two separate phase I/IIa studies evaluated one, two or three doses of STK-001 70mg in children and adolescents who have an established diagnosis of Dravet syndrome.

In the one dose of STK-001 70mg cohort, patients achieved a median reduction of 43% and 57% in convulsive seizure frequency from baseline at three months and six months after the last dose, respectively.

Similarly, in the two or three doses of STK-001 70mg cohort, patients achieved a median reduction of 85% and 74% in convulsive seizure frequency from baseline at three months and six months after the last dose, respectively.

The two OLE studies enrolled eligible Dravet syndrome patients who completed treatment in the phase I/IIa studies of STK-001. Continued treatment with the candidate resulted in durable reductions in convulsive seizure frequency. Improvements in multiple measures of cognition and behavior were also observed in the OLEs.

In a separate press release, Stoke Therapeutics also reported its fourth-quarter 2024 financial results. The company reported a loss of 60 cents per share, narrower than the Zacks Consensus Estimate of a loss of 62 cents.

The company reported revenues of $3 million in the fourth quarter of 2023, which missed the Zacks Consensus Estimate of $4 million. Stoke Therapeutics earns revenues from upfront license fees and services provided under a license and collaboration agreement with Acadia Pharmaceuticals.

Research and development expenses were $21.8 million in the reported quarter, marginally up from the $21.1 million reported in the year-ago quarter.

General and administrative expenses were $10.6 million in the fourth quarter of 2023, up about 13% from the year-ago quarter.

Operating expenses increased primarily due to improvements in costs associated with operations and development activities for pipeline candidates.
