Acelyrin has raised $540 million in an initial public offering, the largest for a biotechnology startup since early 2021 and one of only a handful by young drugmakers this year. The company said Thursday it sold 30 million shares at $18 apiece, exceeding the projections it set earlier this week. It will start trading Friday on the Nasdaq under the ticker symbol “SLRN.” The pace of biotech IPOs has slowed considerably since 2021, when a record 104 startups flooded Wall Street, according to data compiled by BioPharma Dive. The following year, the number of new stock offerings fell by about 80%. Until this week, only five companies had priced a new offering in 2023, the sector’s slowest start in at least five years. The value of those offerings has also trended downwards. Prior to Acelyrin’s offering, nine of the last 15 biotech startups that went public raised $15 million or ...
Some types of epilepsy medicine taken during pregnancy are associated with an increased risk of severe psychiatric disorders in children. This is the conclusion of a comprehensive study of 38,000 children of mothers with epilepsy by researchers from Aarhus University. The research is published in the journal JAMA Neurology. While it has long been known that some forms of epilepsy medicine used during pregnancy are associated with a risk of birth defects, this new study is the most comprehensive study of children’s mental health so far. Among other things, the researchers found a worrying link between the antiseizure medication valproat and the child’s risk of developing a number of different psychiatric disorders. “Our study shows that four out of ten children born to mothers with epilepsy who had used valproat during pregnancy were diagnosed with a psychiatric disorder before the age of 18, and that the drug was particularly associated with an ...
The US Food and Drug Administration (FDA) has issued new draft guidance on the implementation of decentralised clinical trials (DCTs), in which some or all trial-related activities occur at locations other than traditional investigation sites. This could include carrying out clinical tests at a local facility rather than a research medical centre, or conducting follow-up visits in the participants’ homes using telemedicine. The 16-page document provides recommendations for sponsors, investigators and other stakeholders on the use of these trials, which the agency expects’ will play an important role in addressing public health needs’. ‘By reducing barriers to participation, we expect that DCTs will increase the breadth and diversity of participants in clinical trials and improve accessibility for those with rare diseases or mobility challenges,’ the FDA said in a statement. The guidance covers recommendations on topics such as DCT design, the use of digital health technologies for remote patient monitoring, ...
Patent will allow the development of an industrial biomarker analysis kit which could be available worldwide. BioSenic – a company focusing on in autoimmune and inflammatory diseases – has announced that it has submitted a vital patent in relation to the use of its ATO platform. The patent is referred to as a ‘Diagnostic method for detecting the pathological correlates of chronic graft-versus-host disease (cGvHD) using particular cytokine or chemokine biomarkers’ and has duly been submitted to the European Patent Office desk for consideration. It also covers the use of a quantitative system of evaluating the impact of medications developed to change the course of cGvHD. Two years ago, BioSenic successfully concluded a national multi-location, single-arm phase 2 study in five university hospitals across France. During the trial, BioSenic treated 21 cGvHD patients with an intravenous formulation known as Arscimed. Subsequently, BioSenic published positive efficacy and safety results in the ...
Researchers at the Department of Psychiatry and Psychology, Center for Behavioral Health, Neurological Institute at the Cleveland Clinic in Ohio have authored a case report on the positive effects of psilocybin on color blindness. Published in the journal Drug Science, Policy and Law, the researchers highlight some implications surrounding a single reported vision improvement self-study by a colleague and cite other previous reports, illustrating a need to understand better how these psychedelics could be used in therapeutic settings. Past reports have indicated that people with color vision deficiency (CVD), usually referred to as color blindness, experience better color vision after using lysergic acid diethylamide (LSD) or psilocybin (magic mushrooms). There is a lack of scientific evidence for these claims, as researching the effects of these drugs has been highly restricted. Color vision depends on a cluster of three types of photoreceptors known as cones—red, green, and blue sensing retinal photoreceptors with light-sensitive pigments. ...
In a recent study published in the journal Vascular Health and Risk Management, researchers discuss the various non-traditional and traditional practices, as well as the socioeconomic and food insecurity-related limitations associated with adopting diets for heart health. Background Despite considerable progress in medicine and dietary interventions that have improved cardiovascular health, cardiovascular disease remains one of the most prevalent causes of mortality in the United States. Early studies on the association between diet and cardiovascular health reported that a diet rich in fish, vegetables, grains, fruits, and beans was linked to a lower rate of myocardial infarctions. Moreover, the consumption of vegetables and fruits, along with regular exercise, was associated with 40% lower rates of myocardial infarction. Hypertension, excess abdominal fat, dyslipidemia, and type 2 diabetes are some of the risk factors for cardiometabolic diseases that can be modified through changes in the diet. In the U.S., ...

This wearable ultrasound device for monitoring tissue stiffness measures 23 mm x 20 mm x 0.8 mm. [Photo courtesy of University of California San Diego] Wearable ultrasound researchers have developed a stretchable ultrasonic array for serial, noninvasive, 3-D tissue imaging with a penetration depth of up to 4 cm. The latest device out of Sheng Xu’s lab at the University of California San Diego (UCSD) is able to frequently evaluate the stiffness of human tissue. It could be used to measure the progression of cancer, to monitor muscles, tendons and ligaments, and assess the effectiveness of liver and cardiovascular treatments. Xu is commercializing the technology through a UCSD spinoff called Softsonics. “We integrated an array of ultrasound elements into a soft elastomer matrix and used wavy serpentine stretchable electrodes to connect these elements, enabling the device to conform to human ...
In a recent article published in the journal Nature, researchers used a classical concept in computational linguistics to design a new algorithm, LinearDesign, which optimized the structural stability and codon usage of messenger ribonucleic acid (mRNA) sequences. For instance, using this algorithm, researchers could optimize mRNA sequences encoding the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein and use it in mRNA-based coronavirus disease 2019 (COVID-19) vaccines. Background All vaccines based on the relatively new mRNA technology suffer from common limitations, such as mRNA instability and rapid degeneration, which, in turn, lead to poor protein expression and, subsequently, compromised immunogenicity and druggability of all mRNA vaccine products. It also critically hinders the storage, distribution, and efficacy of all mRNA vaccines, including COVID-19 and varicella-zoster virus (VZV) vaccines. Therefore, there is an urgent need for a principled mRNA design algorithm that simultaneously optimizes stability and codon usage of encoding mRNA sequences to ...
The agreement is aimed at developing differentiated ADCs for solid tumours Bristol Myers Squibb (BMS) and Tubulis have announced an agreement aimed at developing differentiated antibody-drug conjugates (ADCs) for solid tumours. ADCs are a class of potent cancer therapies combining the selectivity of antibodies with the potent cell-killing properties of chemotherapy or other anti-cancer agents. Unlike chemotherapy, which works by attacking lots of different cells as well as the cancer, ADCs are designed to target and kill tumour cells while sparing healthy ones. Under the terms of the licensing agreement, the German biotech will receive an upfront payment of $22.75m from BMS and will be eligible for future payments of over $1bn plus royalties. In exchange, BMS will gain exclusive rights to Tubulis’ Tubutecan payloads and P5 conjugation platform for the development of a selected number of highly differentiated ADCs to treat solid tumours. ...
