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.
Despite numerous marketed anti-seizure medications in the U.S., patients with epilepsy continue to experience breakthrough seizures and tolerability issues compounded with drug interactions and side effects, leaving room for companies like Praxis Precision Medicines Inc. to fill treatment gaps. The Boston-based company presented phase IIa proof-of-concept data March 26 showing that in an evaluation of photo paroxysmal response, its once-daily oral small-molecule treatment, PRAX-628, resulted in a complete response in three epilepsy patients receiving 45 mg of the drug and four patients receiving 15 mg for a combined complete response rate of 88%.
Europe may still await its first disease-modifying Alzheimer’s drug after the EMA postponed its decision on Leqembi (lecanemab, Biogen Inc./Eisai Co. Ltd) on March 22, but leading members of the World Dementia Council were in an optimistic mood when they convened in London four days later.
An asset that some investors may have overlooked came through for Axsome Therapeutics Inc., which rolled out phase III data from the trial called Symphony with AXS-12 (reboxetine), which hit the primary endpoint by significantly reducing cataplexy attacks in narcolepsy patients vs. placebo.
South Korean biopharma Aribio Co. Ltd. signed a $770 million deal to sign off exclusive rights to its early Alzheimer’s disease drug, AR-1001 (mirodenafil), in China. The exclusive deal for marketing rights will total about ¥5.59 billion (US$770 million), which includes a non-refundable up-front payment of ₩120 billion (US$90 million) and potential milestone payments, along with royalties.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria. If approved, Emblaveo would be among the first beta-lactam/beta-lactamase inhibitor combos cleared for use in Europe.
Kazia Therapeutics Ltd. has out-licensed paxalisib as a potential treatment for intractable epilepsy in focal cortical dysplasia type 2 and tuberous sclerosis complex disease in a carve-out deal with Sovargen Co. Ltd. for $20.5 million plus sales royalties.
After many years of testing different monoclonal antibodies against amyloid-β protein, the results obtained are far from being outstanding, and the control of the progression and symptoms of Alzheimer’s disease (AD) remains elusive. At the recent AD/PD 2024 conference held in Lisbon, new non-anti-amyloidogenic strategies in the starting line against AD were discussed. Professor Einar Sigurdsson from New York University gave a presentation entitled, “Single domain antibodies for therapy and diagnosis of synucleinopathies and tauopathies.”
Precision psychiatry got some love at two quite different meetings this week, the European Congress of Neuropsychopharmacology’s New Frontiers meeting and BioEurope Spring. The New Frontiers Meeting, an annual two-day meeting dedicated to cutting-edge issues in brain disease research, focused on big-picture and scientific – at times almost philosophical – questions of how to get to a classification scheme for brain disorders that aligns with the underlying biology.
At first glance, the number of drugs that received accelerated approval from the U.S. FDA’s Center for Drug Evaluation and Research (CDER) in 2023 was nothing to write home about. Yes, CDER granted nine accelerated approvals last year, up from six in 2022. But the proportion of novel drugs with accelerated approval was 16% both years. And when compared with the 12 drugs in 2020 and the 14 that received accelerated approval in 2021, last year’s crop was a little lackluster. However, a deeper look at the 2023 class of accelerated approvals shows a historic milestone. For the first time since the path was created in 1992, the number of novel biologics getting accelerated approval at CDER outpaced the number of small-molecule drugs.
