Finding that a lower court went too far with an injunction that ignores the Hatch-Waxman safe harbor protections for drug development, the U.S. Court of Appeals for the Federal Circuit handed Avadel CNS Pharmaceuticals LLC a win of sorts.
PTC Therapeutics Inc. CEO Matthew Klein said the firm “achieved all we set out to [achieve] in phase II” with PTC-518 in Huntington’s disease (HD), but it wasn’t enough to excite Wall Street, as some questioned whether the level of associations between trial findings and efficacy would appease the U.S. FDA. Shares (NASDAQ:PTCT) ended May 5 at $40.65, down $9.30, or 18.6%. Warren, N.J.-based PTC rolled out the most recent data from the Pivot-HD effort in stage 2 and stage 3 HD with PTC-518, an oral, centrally as well as peripherally distributed huntingtin (HTT) pre-mRNA splicing modifier.
Following a complete response letter last year, Satsuma Pharmaceuticals Inc. received U.S. FDA approval of dihydroergotamine nasal powder to treat acute migraine with or without aura. Branded Atzumi, it is the first product that uses Satsuma’s SMART (Simple MucoAdhesive Release Technology) platform that combines an advanced powder and device technology aimed at making delivery more simple.
Bioxodes SA is gearing up fundraising for a follow-up study to the newly released interim phase IIa results of its lead asset in preventing secondary damage after an intracerebral hemorrhagic stroke. Data from the first 16 patients in the phase IIa study show BIOX-101 hit its primary safety and secondary endpoints in an indication that has no approved treatment.
Stem cell implantation is a step closer to becoming the next strategy against Parkinson's disease. Two clinical trials, one in phase I and the other in phase I/II, have demonstrated their safety and potential to restore dopamine production in the brains of patients with this currently incurable neurodegenerative condition. The number of participants in the study is still small, and further research is needed to demonstrate the clinical benefits of these cell therapies.
Genes associated with lysosomal dysfunction increase the risk of Parkinson’s disease (PD), according to a study led by scientists at Northwestern University. The discovery also explains why some people who carry a pathogenic variant of the GBA1 gene develop PD or dementia with Lewy bodies (DLB) and others do not. The key lies in the Commander complex, involved in the transport of proteins to this organelle. This discovery raises the need for combinatorial therapies that act on more than one pathway for this type of neurodegenerative disorder.
After dropping development in December of its lead program, Spruce Biosciences Inc. has found new life by acquiring a BLA-ready enzyme replacement therapy for the rare genetic neurodegenerative disease Sanfilippo syndrome type B. If approved, the therapy, tralesinidase alfa, could bring Spruce a priority review voucher.
Scientists from the Machine Intelligence from Cortical Networks (MICRONS) consortium have published the microconnectome of a cubic millimeter of the mouse brain. This is the most complete map of this organ to date at nanometer resolution for a mammal. It not only contains the structure and connections of each and every cell in that volume of tissue, but is also linked to the neuronal activity of that portion of the CNS, linking anatomy and function in the same cells.
Tryptamine Therapeutics Ltd. is gearing up to enter the clinic with lead compound TRP-8803, an intravenous-infused psilocybin therapy, in patients with binge eating disorder in conjunction with psychotherapy.
Alzheon Inc.’s oral treatment for people in the early stages of Alzheimer’s disease missed its phase III primary endpoint, adding yet another therapy to a long list by many developers that can’t beat dementia. The study also received grant money, which is in increasingly short supply.
