Dive Brief Danaher plans to buy Cambridge, England-based Abcam for about $5.7 billion in cash, the companies announced on Monday. The acquisition would bring together two firms that make equipment and supplies for life sciences companies. Abcam, with a market capitalization of $5.2 billion, would operate as a standalone company under Washington, D.C.-based Danaher, which has a market cap of $191.7 billion. Danaher reportedly outbid other companies including Agilent Technologies, Reuters wrote on Friday, citing people familiar with the matter. Dive Insight Abcam, a maker of antibodies, reagents, biomarkers and assays for life science companies, began a review of strategic alternatives in June. A proxy battle waged this summer between the company’s founder and its CEO attracted “strategic inquiries from multiple parties,” Abcam said in a June statement. The company evaluated more than 20 potential acquirers, Abcam said on Monday. The agreement values Abcam at about $24 per share. The ...
An academic group has published preclinical results with a new antibody that has greater activity and fewer side effects than existing biological therapies for inflammatory conditions. This could translate into a clinical benefit for patients living with rheumatoid arthritis (RA), psoriasis, or inflammatory bowel disease (IBD). Researchers from the University of Birmingham in the UK and the University of Naples Federico II in Italy revealed promising results after designing an antibody that targets a 20-long amino acid sequence in interleukin-17 (IL-17) – a protein important in inflammatory pathways. According to the team, they demonstrated for the first time that this sequence activates the release of cyto-chemokines. The antibody, which has been called Ab-IPL-IL-17, targets this sequence in both IL-17A and IL-17F. In cell studies, it demonstrated an ability to reduce the production of cyto-chemokines and white blood cell migration to inflammation-primed tissue. When the researchers compared it to existing therapies ...
AstraZeneca and Sanofi’s Beyfortus (nirsevimab) has been approved in the US for the prevention of respiratory syncytial virus (RSV) lower respiratory tract disease (LRTD) in newborns and infants born during or entering their first RSV season, the companies announced. The US Food and Drug Administration’s (FDA) decision makes the long-acting antibody the first preventive option approved to protect a broad infant population, including those born healthy at term, preterm, or with specific health conditions that make them vulnerable to severe RSV disease. The approval, which also applies to children aged up to 24 months who remain vulnerable to severe RSV disease through their second RSV season, was based on results from the Beyfortus clinical development programme spanning three pivotal late-stage clinical trials and follows a unanimous vote by the Antimicrobial Drugs Advisory Committee on the favourable benefit-risk profile of the drug. Across all clinical endpoints, a single dose of Beyfortus ...
Seeking to launch their respiratory syncytial virus (RSV) prevention antibody for infants later this year, Sanofi and AstraZeneca have cleared one more regulatory hurdle.Thursday, experts on the FDA’s Antimicrobial Drugs Advisory Committee voted 21 to 0 that nirsevimab boasts a favorable benefit-risk profile to protect against RSV-associated lower respiratory disease in infants born during or entering their first RSV season. On a separate question of whether the drug has a favorable benefit-risk profile in children up to 24 months of age who remain vulnerable through their second RSV season, the vote was 19 to 2 in favor of the drug. “Most babies hospitalized with RSV are born at term and healthy, which is why interventions specifically designed to protect all infants are likely to result in the greatest impact,” Sanofi’s executive vice president of vaccines, Thomas Triomphe, said in a Thursday statement. “We are encouraged by the Advisory Committee’s positive ...
By Jamie Gumbrecht, CNN CNN — Advisers to the US Food and Drug Administration voted Thursday to endorse a monoclonal antibody designed to protect infants and some young toddlers from RSV. Members of the agency’s Antimicrobial Drugs Advisory Committee voted 21-0 that the benefit-risk profile of nirsevimab was favorable in infants and 19-2 that it was favorable in children up to 24 months who are vulnerable to severe respiratory syncytial virus. Next, the FDA will consider the advice of the advisers and decide whether to approve the treatment. The monoclonal antibody, nirsevimab, was developed by AstraZeneca and Sanofi. It’s designed to be given to infants in a single shot at birth or just before the start of a baby’s first RSV season, or as a larger dose in a second RSV season in children who are highly vulnerable. If approved, it will be the first single-dose preventative treatment for all ...
Updated dose expansion data of the phase I STRO-002-GM1 study have been presented today by Ana Oaknin, Principal Investigator of the Vall d’Hebron Institute of Oncology’s (VHIO) Gynecological Malignancies Group, on the ground at the 2023 Annual Meeting of the American Society of Clinical Oncology (ASCO), 2-6 June in Chicago, USA. This global study was designed to evaluate the efficacy and safety of the novel FolRα-targeting antibody drug conjugate (ADC) luveltamab tazevibulin (STRO-002 – luvelta) in patients with recurrent epithelial ovarian cancer with identified expression levels of folate receptor alpha (FolRα) higher than 25%. This ADC induces cytotoxic and immunologic cell death, and using site-specific conjugation technology and is designed to target a broad range of FolRα-expressing ovarian tumors. “Folate receptor alpha is a folate-binding protein overexpressed on ovarian and several other epithelial malignancies. Its overexpression in solid tumors promotes cancer cell proliferation and persists in metastatic or recurrent disease ...
In a recent study published in the Eurosurveillance Journal, researchers conducted a retrospective analysis of seroprotection against tetanus and diphtheria among residents in Austria following an increase in diphtheria cases since 2022 in Europe. Background Diphtheria is an infection caused by Corynebacterium diphtheriae resulting in the inflammation of mucous membranes in the throat and nose. While an increase in the incidence of diphtheria among migrants in Europe was observed beginning in August 2022, recent studies also found that the concentrations of antibodies against diphtheria in adults in approximately 18 countries in the European Union were negligible. Although no diphtheria outbreaks have been reported among the general population of European Union countries, the low seroprotection increases the risk of disease outbreaks. Estimating the seroprevalence among the population could help determine the risk of a diphtheria outbreak and increase awareness about the importance of vaccines to ensure ...
Christopher Newman Editor “This is a showdown about whether the most valuable patents in the entirety of the patent system are valid,” one law expert said. The nearly decade-long patent feud between Amgen and rivals Sanofi and Regeneron has divided the biopharmaceutical industry, with drugmakers taking different sides in a U.S. Supreme Court case that could have far-reaching effects. At issue are patents for powerful cholesterol-lowering medicines known as PCSK9 inhibitors. Regeneron and Sanofi brought the first, Praluent, to market in 2015. Amgen followed one month later with a similar medicine, called Repatha. The drugs work by boosting liver cells’ ability to hoover up LDL, or “bad,” cholesterol. Amgen has long claimed Sanofi and Regeneron infringed on patents it secured for Praluent. The fight has slowly winded its way through the U.S. legal system to reach the Supreme Court. There, judges could disrupt the $160 billion-per-year market for antibodies by deciding how broadly ...
Bristol Myers Squibb (BMS) has revealed top-line data from a Phase II/III trial evaluating its PD-1 inhibitor Opdivo plus its investigational anti-LAG-3 antibody relatlimab in previously untreated metastatic or unresectable melanoma. The RELATIVITY-047 trial is evaluating a fixed-dose combination of Opdivo (nivolumab) and relatlimab compared to Opdivo alone in these patients. According to BMS, the trial met its primary endpoint of progression-free survival, with follow-up for the secondary endpoint of overall survival still ongoing. Although the company did not disclose the actual figures for the combination treatment, BMS said it would present the results at an upcoming meeting and discuss the findings with regulatory authorities. Lymphocyte-activation gene 3 (LAG-3) is expressed on effector T cells and regulatory T cells (Tregs). It regulates an inhibitory immune checkpoint pathway that limits the activity of T cells, which is believed to cause an impaired ability to attack tumour cells. In cancer, T cells exhibit progressive exhaustion ...
The coronavirus antibody test is performed to determine the blood level of antibodies that are developed against the virus. This test determines if a person was infected by a coronavirus in the past. Image Credit: joel bubble ben/Shutterstock.com What is coronavirus? Coronaviruses are a group of viruses that cause respiratory infections in humans. The infections can range from mild (common cold) to severe (Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS)). Importantly, coronavirus disease 2019 (COVID-19) is a severe, highly infectious disease caused by very recently identified coronavirus namely severe acute respiratory syndrome coronavirus 2 (SARS-CoV 2). How coronavirus is detected in COVID-19 patients? Presently, two types of viral tests are approved by the U.S Food and Drug Administration (FDA): molecular test and antigen test. In molecular tests, the viral genetic material is detected using polymerase chain reaction (PCR). The test is done using biological fluid collected from ...
