UPDATE: Zogenix stock rockets 195% premarket on news of positive epilepsy drug trial

Zogenix Inc. shares rocketed almost 200% Friday, after the company said a late-stage trial of a treatment for a rare type of epilepsy called Dravet syndrome met its main goal. The Phase 3 trial of the drug, ZX008, low-dose fenfluramine hydrochloride, met its primary endpoint of reducing the frequency of convulsive seizures in children and young adults. “If approved, ZX008 could play an important role in treating this devastating condition,” said Joseph Sullivan M.D., director of the Pediatric Epilepsy Center in UCSF Benioff Children’s Hospital San Francisco, and head of the trial. Dravet syndrome is a rate, lifelong form of epilepsy that begins in the first year of life with frequent seizures and other symptoms, including behavioral and developmental delays, orthopedic conditions and delayed language. The disease affects 1 in 15,700 individuals, according to the Dravet Syndrome Foundation. Zogenix shares were halted for the news before surging as the halt was lifted. They had gained about 6% in 2017 through Thursday, while the S&P 500 has gained about 12%.

Merck & Co. said Friday it would discontinue the development of the investigational combination regimens MK-3682B and MK-3682C for the treatment of chronic hepatitis C, after a review of available Phase 2 efficacy data.

PTC Therapeutics gains after FDA panel votes against drug approval

PTC Therapeutics Inc. stock gained 10% in after-hours action Thursday after trading was halted for the entire regular session as a Food and Drug Administration panel discussed the company’s Duchenne muscular dystrophy drug. The panel eventually voted not to approve the drug, saying that more testing was required to prove its efficacy, though they did not completely reject the drug. The FDA does not have to follow the panel’s recommendation, as it showed in controversially approving a drug for the same disease last year from Sarepta Therapeutics Inc. despite a panel recommendation against the approval. After being halted at Wednesday’s closing price of $17.46 all day, PTC shares resumed trading just before 6 p.m. Eastern time Thursday and topped $19.

Twitter finds hundreds of Russian-linked accounts

Twitter Inc. has found hundreds of accounts that have ties to Russian operatives, the company said Thursday in a blog post. The social network has linked just over 200 accounts to 470 pages and accounts on Facebook Inc.’s platform which have ties to a Russian troll farm that is charged with interfering in the 2016 U.S. election. Twitter also said that three accounts from the Kremlin-linked news site RT had spent $274,100 on ads in 2016, targeting U.S. followers of the “mainstream media” and mostly promoted RT tweets about news stories, the blog said. The company met with congressional investigators Thursday morning as a part of a widening probe into Russian interference during the 2016 campaign and how they used tech titans such as Alphabet Inc. , Facebook and Twitter. Bots also played a role in the election and Twitter said that it took action on thousands of tweets and accounts that attempted to suppress or interfere with voting rights, though these accounts did not have “obvious Russian origin” the blog said. Twitter stock is edged down less than 1% to $16.84 after hours. The company’s shares are up 3.4% this year, as the S&P 500 index rose 12%.
