Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease, the incidence of population over 60 years old in China is 1.37%, Parkinson's disease is often accompanied by various non-motor symptoms, such as salivation. Salivation can occur at any time in Parkinson's disease, with an incidence of 32% to 74%, often leading to social embarrassment, skin infections, bad breath, aspiration pneumonia, etc. This not only reduces the quality of life of patients, but also increases the burden on caregivers. Salivation can improve symptoms with botulinum toxin injections, medications, and non-drug treatments. Dihydroergot mesylate has been shown to be effective in the treatment of salivation in patients with Parkinson's disease, and this study will further observe the medium- to long-term efficacy of the drug on salivation symptoms.

Low blue-hazard white-light emission based on color-tunable triplet-triplet annihilation upconversion

Article

Author: Shi, Yizhong ; Wan, Shigang ; Dong, Yuxiang ; Guo, Cheng ; Gou, Haodong ; Chen, Shuoran ; Zheng, Daoyuan ; Ye, Changqing

The commonly used artificial light sources, such as fluorescent lamps and white light-emitting diodes, often have a high ratio of blue light emission, which poses potential blue light hazards, especially one of the main culprits leading to eye diseases. Therefore, developing novel white lighting sources with low blue-hazard is highly appreciated. In this work, an air-stable and color-tunable triplet-triplet annihilation upconversion (TTA-UC) mechanism was proposed to realize the low blue-hazard white-light emission. The proposed design was composed of three primary RGB colors from the annihilator (9,10-diphenylanthracene, DPA), the laser excitation source, and the photosensitizer (palladium (II) octaetylporphyrin, PdOEP), respectively. The introduction of oil-in-water (o/w) microemulsion can effectively block the potential oxygen-induced triplet-quenching and benefit high UC efficiency. Moreover, either raising ambient temperatures or adding isobutanol can activate the UC process to yield white-light emission. Notably, the white-light emission with a Commission Internationale de l'Eclairage (CIE) coordinate of (0.33, 0.33) as well as a low ratio of blue emission (14.2 %) was achieved at an ambient temperature of 42 °C. Therefore, the proposed air-stable TTA-UC mechanism can significantly lower the blue-hazard and provide a novel solution for applications in lighting and display.

Long-Term (12-Month) Safety and Tolerability of STS101 (Dihydroergotamine Nasal Powder) in the Acute Treatment of Migraine: Data from the Phase 3 Open-Label ASCEND Study

Article

Author: Tepper, Stewart J ; Rapoport, Alan M ; Ailani, Jessica ; Kirby, Louis ; Albrecht, Detlef ; Strom, Shannon

BACKGROUND AND OBJECTIVESTS101 is an investigational drug-device combination comprising 5.2 mg dihydroergotamine (DHE) powder (6.0 mg DHE mesylate) in a single-use nasal delivery device for the acute treatment of migraine. The primary objective of the ASCEND trial was to assess long-term safety and tolerability of STS101 in the acute treatment of migraine attacks across 12-18 months, with secondary objectives describing efficacy.METHODSASCEND was an open-label study of STS101 in adults aged 18-65 years with a ≥ 1 year history of migraine with or without aura, with onset before the age of 50 years and 4-12 migraine attacks/month and < 15 headache days/month in each of the 3 months prior to screening. Exclusion criteria included diagnosis of non-migraine headache, history of cerebrovascular disease, and ≥ 2 cardiovascular risk factors. After establishing eligibility, participants could self-administer STS101 5.2 mg as needed for up to 2 doses within 24 h to treat a single migraine attack and up to 12 doses/month. Safety and tolerability evaluations included physical and nasal examinations, vital signs, laboratory tests, and treatment-emergent adverse event (TEAE) assessments. Participants used an electronic diary to record exploratory efficacy parameters, including intensity of headache pain and associated migraine symptoms (photophobia, phonophobia, and nausea). Participant impression questions were asked at months 3, 6, and 12.RESULTSOf the 6610 migraine attacks treated with a total of 8234 STS101 doses in 344 participants, 945/6610 (14.3%) were associated with a TEAE. Events were predominantly mild or moderate in nature and rarely led to premature study discontinuation (15/344 [4.4%] participants). Treatment was associated with rapid onset of freedom from pain (36.6%, 67.1%, and 85.5% of treated attacks 2, 4, and 24 h post-dose, respectively), freedom from most bothersome symptoms (54.3%, 79.6%, and 91.3%), and headache relief (66.5%, 89.1%, and 94.3%). Most participants rated treatment results as good or very good and ease of use as easy or very easy at all time points (months 3, 6, and 12) and indicated they were likely or very likely to use STS101 again.CONCLUSIONSThe repeated long-term, as-needed use of STS101 was well tolerated, demonstrating a favorable safety profile in the acute treatment of migraine attacks in appropriately indicated adults. Exploratory efficacy evaluations indicated beneficial effects, which warrant further evaluation.TRIAL REGISTRATIONClinicalTrials.gov identification NCT04406649.

Activation of α7 nicotinic acetylcholine receptor augments nerve growth factor action on PCtrk cells

Article

Author: Niimi, Y. ; Mutoh, T ; Niimi, Y ; Ueda, Akihiro ; Mutoh, T.

Although cigarette smoking is known to be a critical risk factor for various organ systems and cancers, accumulating evidence indicates that nicotine - a main constituent of cigarette smoking - can exert neuroprotective effects on neuronal cells through nicotinic acetylcholine receptors (nAChRs). However, the precise molecular mechanisms for nicotinic neuroprotective actions remain to be fully elucidated. In this study, we examine the effects of agonists, such as nicotine and PNU282987, on tropomyosin-related kinase (Trk)-dependent neuroprotective pathways in PC12 cells overexpressing a Trk neurotrophin receptor (PCtrk cells). We found that even considerably higher concentrations (mM range for nicotine and µM range for PN282987) of nAChR agonists exert favorable effects, such as the augmentation of nerve growth factor (NGF)-induced Trk neurotrophin receptor autophosphorylation of tyrosine residues and NGF-induced neurite extension. Moreover, nicotine upregulated reactive oxygen species (ROS) levels in the cells. ROS production was completely cancelled by pretreatment with Mito-Tempo, a mitochondria-targeted antioxidant, indicating that the main source of ROS production by nicotine was mitochondria. Furthermore, treatment with nAChR agonists appeared to induce autophagic flux, as evidenced by the upregulation of LC3-II expression in cells. Furthermore, sucrose density ultracentrifugation of nicotine-treated cells clearly disclosed the augmented recruitment of α7nAChR protein into the lipid rafts fraction of the membrane. Intriguingly, a pull-down assay of anti-Trk antibody immunoprecipitates clearly included α7nAChR protein, indicating that Trk and α7nAChR proteins form a complex. These results reveal a new molecular interaction between activated α7nAChR and Trk protein that may serve as a new molecular basis of nicotine-induced neuroprotective action.

Pulmatrix Announces Third Quarter 2024 Financial Results and Provides Corporate Update

Closed transactions with MannKind Corporation validating the potential value of iSPERSE™ technology Pursuing strategic alternatives to further leverage iSPERSE™ and optimize the potential of PUR3100 Completed PUR1900 wind down activities Cash runway projected into Q4 2026 FRAMINGHAM, Mass., Nov. 8, 2024 /PRNewswire/ -- Pulmatrix, Inc. ("Pulmatrix" or the "Company") (Nasdaq: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious central nervous system and pulmonary disease using its patented dry powder inhalation iSPERSE™ technology, today announced third quarter financial results for 2024 and provided a corporate update on its clinical assets. Peter Ludlum, Interim Chief Executive Officer of Pulmatrix, commented, "Our focus in the third quarter has been to continue our cost saving measures, complete the wind down activities for the Phase 2b study for PUR1900 and close the transactions with MannKind. Repositioning ourselves as a virtual company has allowed us to improve our balance sheet and continue to focus on strategic alternatives that leverage the potential of PUR3100 and our iSPERSE™ technology." Third Quarter 2024 and Recent Program and Corporate Highlights PUR3100 PUR3100 is an orally inhaled dihydroergotamine (DHE) engineered with iSPERSE™ for the treatment of acute migraine. Pulmatrix is currently exploring financing or partnership arrangements to develop and initiate a potential Phase 2 clinical study for PUR3100. In 2023, Pulmatrix announced the FDA's acceptance of an IND application for PUR3100 and receipt of a "study may proceed" letter to proceed with a Phase 2 study, positioning PUR3100 as Phase 2-ready. The IND includes a Phase 2 clinical protocol where safety and preliminary efficacy of PUR3100 will be investigated in patients with acute migraine. The planned Phase 2 trial builds on the Phase 1 trial results, which were published in 2023 and presented at the American Headache Society's 65th Annual Meeting in June 2023. In May 2024, Pulmatrix announced a peer-reviewed publication of Phase 1 clinical results in Headache: The Journal of Head and Face Pain. The study showed that PUR3100 achieved peak exposures in the targeted therapeutic range and time to maximum concentration occurred at five minutes after dosing at all dosing levels. The PUR3100 dose groups also showed a lower incidence of nausea and no vomiting compared to observations of nausea and vomiting in the intravenously (IV) administered DHE dose group. PUR1800 PUR1800 is a Narrow Spectrum Kinase Inhibitor, engineered with our iSPERSE™ technology, for the treatment of acute exacerbations in chronic obstructive pulmonary disease (AECOPD). In 2023, Pulmatrix presented complete results from a Phase 1b study of PUR1800 for AECOPD, indicating PUR1800 was safe and well tolerated with no observed safety signals. The topline data, along with the results from chronic toxicology studies, support the continued development of PUR1800 for the treatment of AECOPD and other inflammatory respiratory diseases. Pulmatrix plans to pursue partnership or other alternatives to monetize or advance PUR1800. PUR1900 PUR1900 is the Company's inhaled iSPERSE™ formulation of the antifungal drug itraconazole for indications where an orally inhaled antifungal may provide a therapeutic benefit or fulfill an unmet medical need. In agreement with its partner Cipla, Pulmatrix has stopped patient enrollment for the Phase 2b study of PUR1900. The decision to stop the study was unrelated to any safety concerns. This study had been ongoing since the first quarter of 2023. The Company completed all Phase 2b wind down activities within the third quarter of 2024 as planned. After the study wind down, Pulmatrix will bear no further financial responsibility for the development of PUR1900 and will receive 2% royalties on any potential future net sales by Cipla outside the United States. Within the United States, Pulmatrix and Cipla will seek to monetize PUR1900. iSPERSE™ Technology Pursuant to the Cross License Agreement with MannKind the Company granted (i) an exclusive license for iSPERSE formulations of Clofazimine, (ii) an exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE for the treatment of nontuberculous mycobacteria lung disease in humans, (iii) an exclusive license for iSPERSE formulations of insulin, (iv) a non-exclusive license for iSPERSE for the treatment of endocrine disease in humans, and (v) a non-exclusive license for formulations of iSPERSE for the treatment of interstitial lung diseases (including IPF, PPF and other related lung diseases). As of September 30, 2024, Pulmatrix's patent portfolio related to iSPERSE™ included approximately 147 granted patents, 18 of which are granted U.S. patents, with expiration dates from 2024 to 2037, and approximately 51 additional pending patent applications in the U.S. and other jurisdictions. Third Quarter 2024 Financial Results Revenues decreased approximately $1.4 million to $0.4 million for the three months ended September 30, 2024, compared to $1.8 million for the three months ended September 30, 2023. The decrease is primarily related to decreased revenue under the Cipla Agreement related to fewer reimbursable expenses incurred due to the wind down of the PUR1900 Phase 2b clinical trial, as compared to the corresponding period in the previous year. Research and development expenses decreased approximately $3.2 million to $0.8 million for the three months ended September 30, 2024, compared to $4.0 million for the three months ended September 30, 2023. The decrease was primarily due to less employment and other operating cost following the MannKind cross-license agreement announced in May 2024 (the "MannKind Transaction"), which included a transfer of the Company's leased office and laboratory facilities, as well as less cost incurred on the PUR1900 program, for which the winding down of the Phase 2b clinical trial was completed during the three months ended September 30, 2024. General and administrative expenses increased approximately $0.5 million to $2.2 million for the three months ended September 30, 2024, compared to $1.7 million for the three months ended September 30, 2023. The increase was primarily due to one-time employee separation costs. The Company's total cash and cash equivalents balance as of September 30, 2024, was $10.8 million. The Company anticipates that its cash position, based on operational efficiencies and prioritization of spending, is sufficient to fund its operations into the fourth quarter of 2026.

Exploratory Efficacy Endpoints showed that STS101provided rapid freedom from pain (37% of attacks), and rapid freedom from most bothersome symptoms (54% of attacks) at 2 hours and sustained treatment benefits over 48 hours after dosing. DURHAM, N.C. , Oct. 8, 2024 /PRNewswire/ -- Satsuma Pharmaceuticals, Inc., a late-stage biopharmaceutical company currently seeking regulatory approval from the U.S. Food and Drug Administration for STS101 (dihydroergotamine (DHE) nasal powder), a novel investigational therapeutic product candidate for the acute treatment of migraine, and its corporate parent, Shin Nippon Biomedical Laboratories, Ltd. (TSE:2395), today announced publication the STS101 ASCEND Phase 3 long-term, open-label safety trial in CNS Drugs. STS101 is the only product to combine Satsuma’s proprietary SMART™ (Simple MucoAdhesive Release Technology) with an easy-to-use, easy-to carry nasal delivery device. “We are proud to announce the publication of our pivotal safety data, which further reinforce the potential for STS101 to be a unique, well-tolerated treatment that, subject to approval by the FDA, has the potential to deliver rapid and enduring symptom relief for patients with acute migraine,” said Ryoichi Nagata , President and CEO of Satsuma, M.D., Ph.D., FFPM. “We were particularly pleased to see that a vast majority of patients reported that STS101 was easy to use over the entire duration of the study.” The publication, can be found here, “I am pleased that the data demonstrates that STS101 was safe, well tolerated, and easy for patients to use over the long term. This is exciting and important information for people living with migraine who have experienced inadequate relief with existing therapies and the practitioners who treat them who are in need of new options,” said Stewart Tepper , MD, Vice President of the New England Institute for Neurology and Headache in Stamford, Connecticut . “Even with the introduction of new treatment options in the past few years, there is a critical need for novel non-oral treatment options for patients who are often unable to achieve rapid relief with oral routes of administration.” About the ASCEND Study ASCEND Study was a pivotal Phase 3 open-label study that evaluated the safety, tolerability, exploratory efficacy, and patient acceptability of STS101. The trial was conducted at 54 sites in the United States and enrolled 482 patients who had a documented diagnosis of migraine with or without aura, with 4 to 12 migraine attacks per month in each of the 3 months prior to the study. In the trial, 446 patients received at least one dose of STS101 and used 10,137 doses of STS101 for up to 18 months. In the study, STS101 was well tolerated over up to 18-months of as-needed use, with STS101-related treatment-emergent AEs were reported in 14.3 percent of migraine attacks treated with STS101 device planned for commercialization. Furthermore, there was a low rate of adverse event related discontinuation (7% percent). No new safety signals were observed in this study following STS101 treatment. The study also assessed patient-reported exploratory efficacy. Pain freedom, the most bothersome symptom freedom, and pain relief at 2 hours post-STS101 were self-reported in an eDiary, with two-thirds of patients reporting pain relief at two hours following STS101 administration. Exploratory endpoints included a patient global impression questionnaire (PGI) assessing the patient’s impression of STS101 usability and effectiveness. Most patients reported a positive overall impression of STS101, STS101 was easy to use, and they would use the STS101 if available.
