【EXPERT Q&A】What are Radioactive Drug Conjugates (RDCs)?

Drugdu.com expert’s response: Radioactive Drug Conjugates (RDCs) represent a novel class of therapeutic agents that combine the strengths of precise targeting and potent killing capabilities. By linking radioactive nuclides to ligands (such as antibodies, peptides, small molecules, etc.) through linkers and chelators, RDCs achieve precise localization and effective eradication of target cells. Below, I will elaborate on RDCs from four aspects: definition and structure, advantages and applications, classification, as well as challenges and prospects. I. Definition and Structure Definition: RDCs are drug formulations that integrate radioactive nuclides with targeting molecules (ligands) through linker arms (connectors), aimed at delivering precise strikes against tumor or other disease targets. Structure: RDC drugs consist primarily of targeting ligands, linker arms, chelators, and nuclide conjugates. The targeting ligands recognize and bind to specific target cells or tissues; linker arms connect the targeting ligands to the radioactive nuclides; chelators stabilize the radioactive nuclides, preventing their premature ...

Balance Medical creates a new era of TAVR2.0

On August 22nd, the National Medical Products Administration announced that it has recently approved the registration applications for two innovative products, the “Transcatheter Aortic Valve System” of Beijing Balance Medical Technology Co., Ltd. (hereinafter referred to as “Balance Medical”). The transcatheter aortic valve system is mainly used to treat aortic valve stenosis, and there are two main treatment options: surgical thoracotomy for valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). TAVR can be roughly divided into ball expanding and self expanding instruments. Compared to SAVR, TAVR has the characteristics of no need for thoracotomy and extracorporeal circulation, minimal trauma, and fast recovery, providing a safer treatment option for high-risk surgical patients. However, in the Chinese market, the penetration rate of TAVR is still relatively low, far below the global level, and a large amount of demand has not been met, with broad prospects. According to Frost&Sullivan data, there were ...

Eli Lilly’s Zepbound to be issued in single-dose vials for self-payers

Eli Lilly and Company has announced the availability of Zepbound (tirzepatide) in 2.5mg and 5mg single-dose vials for self-pay for adults with obesity. The move significantly expands the supply of Zepbound in response to high demand and offers a more affordable option for those who self-pay. The vials are priced a minimum of 50% lower than the list price of other incretin medicines for obesity. Lilly has introduced a new self-pay pharmacy component within LillyDirect, enabling patients with a valid prescription to purchase Zepbound directly. The initiative ensures the authenticity of the medicine and safeguards patients from counterfeit products. Lilly also announced its commitment to ensuring that Zepbound is used appropriately and not for cosmetic weight loss, implementing a multi-step verification process for dispensing. The 2.5mg Zepbound vial costs $399 for a four-week supply while the 5mg dose costs $549 – both representing significant savings compared to other treatments. The ...

MHRA approves Astellas’ Vyloy combination for gastric cancer

The Medicines and Healthcare products Regulatory Agency (MHRA) has approved Astellas Pharma’s Vyloy (zolbetuximab) as part of a first-line combination treatment for a subset of gastric cancer patients. The monoclonal antibody has been authorised for use alongside chemotherapy to treat adults with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastro-oesophageal junction (GEJ) adenocarcinoma whose tumours are claudin 18.2 positive. In the UK, adenocarcinomas, which develop from cells in the innermost lining of the stomach, account for most cases of gastric cancer, with around 6,600 people diagnosed every year. Most cases go undetected until an advanced stage, as the disease rarely causes early symptoms and tends to develop slowly over a number of years. Vyloy is now the only licensed treatment to target the claudin 18.2 protein, which is expressed in gastric, oesophageal, lung and ovarian tissues, and is administered intravenously every two to three ...

Improving tracking of AMR bacteria in hospitals using new genomic technique

Using a genomic approach, researchers have developed a way to simultaneously track the spread of multiple common antibiotic-resistant bacteria in hospitals. Current methods culture and sequence all pathogens separately so the new sequencing technique could help to prevent and manage hospital infections more quickly and effectively. Published in the Lancet Microbe, the proof-of-concept study from the Wellcome Sanger Institute, the University of Oslo, Fondazione IRCCS Policlinico San Matteo in Italy and collaborators captured the whole population of pathogenic bacteria found in the gut, upper airways and lungs of patients in multiple hospital intensive care units (ICUs) and ordinary wards during the first wave of the COVID-19 pandemic in 2020. The team found that, with most ICU patients colonised by several treatment-resistant bacteria and all patients colonised by at least one, they were able to determine which type of bacteria each patient had. Antimicrobial resistance (AMR) occurs when bacteria, viruses, fungi ...

AI-Based Digital Pathology Platform Improves Lung Cancer Diagnosis

Lung cancer ranks among the most prevalent and fatal cancers worldwide. Current treatment strategies for lung cancer patients rely on pathological examinations, which can reveal genetic mutations specific to the patient’s cancer, facilitating personalized treatment approaches. Over the last few years, pathology has evolved dramatically due to digital advancements, making traditional microscopes obsolete. Tissue samples are now digitized and analyzed via computer screens, which is essential for employing sophisticated artificial intelligence (AI)-based analytical methods. These AI technologies can extract additional insights from pathological tissue sections that were previously unattainable. A team of researchers at the University of Cologne (Cologne, Germany) has developed an AI-driven digital pathology platform that can revolutionize the analysis of lung cancer tissues. This platform utilizes newly developed algorithms to perform fully automated examination of digitized lung cancer tissue sections, offering faster and more precise analyses than traditional methods. Detailed in their publication in the journal Cell ...

Novel Blood-Based Risk Score Based on Lipids Improves Prediction of Heart Disease

In the field of cardiovascular health, some individuals fall into an ambiguous “intermediate zone” of risk for heart attacks or strokes—neither distinctly low nor high-risk, yet potentially on the cusp of heart disease. This grey area calls for improved methodologies for accurate risk prediction. Traditionally, risk assessments like the widely recognized Framingham Risk Score have utilized factors such as levels of ‘good’ and ‘bad’ cholesterol to categorize individuals into risk groups. However, these conventional tools have several limitations, especially in identifying the risks for those in this intermediate category. This oversight is particularly critical as heart disease can progress silently, making early detection crucial to avoid late-stage interventions that are less effective. Now, scientists have developed and validated a novel, blood-based risk score based on lipids (fats in the blood). The tool, outlined in a paper published in the Journal of the American College of Cardiology, was developed by scientists ...
