The U.S. FDA caught up with four makers of CPAP cleaning machines in the form of warning letters advising the manufacturers that the claims made for their systems fall under the definition of a regulated medical device. In two of these warning letters, the FDA said it had been in touch with the manufacturer for at least two years, indicating that the agency has been steadily working on enforcement activities in this space for some time.
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide and is characterized by an abnormal inflammatory reaction of the lungs to inhaled particles, such as cigarette smoke. On the other hand, the transcription factor interferon responsive factors (IRFs) are key elements in the production of type I and III interferons. A group of researchers in Italy looked into the relationship between interferon regulatory factor 3 (IRF3) and COPD outcomes.
Glucocorticoids are the standard treatment to treat inflammation in asthma, however, they are often associated with cardiovascular disease, osteoporosis or immune suppression risk with chronic use. Novel strategies to combine with traditional treatments, such as those intended to restore hydrogen sulfide (H2S) levels, have emerged as options for treating severe uncontrolled asthma with frequent exacerbations.
Addex Therapeutics Ltd. and Indivior plc have announced the selection of clinical candidates from their γ-aminobutyric acid subtype B (GABA-B) positive allosteric modulator (PAM) research collaboration.
Immorna Biotherapeutics Inc. has received a grant from the Bill & Melinda Gates Foundation to support the clinical development of JCXH-108, a monovalent respiratory syncytial virus (RSV) vaccine based on Immorna’s proprietary mRNA and ready-to-use (RTU)-lipid nanoparticle (LNP) technologies.
Researchers have identified a gene associated with whether patients hospitalized with respiratory viral infections recover rapidly or face life-threatening complications. The gene has the potential to be used as a diagnostic tool or biomarker, which could help triage patients suffering from severe respiratory infections. Having such a biomarker would help clinicians in their early risk assessments to manage their intervention strategies.
Human rhinoviruses (hRVs) are associated with upper respiratory tract infections such as the common cold, otitis media or sinusitis. In immunocompromised individuals or older people, hRVs can exacerbate existing pulmonary conditions such as asthma or chronic obstructive pulmonary disease.
Reistone Biopharma Co. Ltd. has described phosphodiesterase PDE4B1 inhibitors reported to be useful for the treatment of asthma, chronic obstructive pulmonary disease, acute respiratory distress syndrome, atopic dermatitis, overactive bladder, psoriasis, ulcerative colitis and urticaria, among others.
Beijing Primegene Therapeutics Co. Ltd. has identified azacycloalkane compounds acting as rho kinase 1 (ROCK1; p160-ROCK) and/or rho-associated protein kinase 2 (ROCK 2) inhibitors reported to be useful for the treatment of asthma, cancer, insulin resistance, neurodegeneration, osteoporosis and renal failure.
Airna Corp. Inc., of Cambridge, Mass., announced it has closed an oversubscribed $60 million financing round, bringing its total series A funding to $90 million.
