New insights on gadoquatrane and gadobutrol being presented at ECR 2024

Gadoquatrane, Bayer’s novel investigational macrocyclic gadolinium-based contrast agent (GBCA) currently in Phase III, has the potential to enable a substantially lower clinical gadolinium (Gd) dose for patients undergoing a contrast-enhanced MRI. New preclinical and clinical data for gadoquatrane as well as literature-based reviews of published data on the safety and efficacy of Bayer’s established macrocyclic GBCA gadobutrol are being presented at this year’s ECR:

·         Quantification and assessment of the chemical form of residual gadolinium in the skin after repeated administration of gadolinium-based contrast agents in rats

This study investigated the distribution and chemical form of the applied Gd-based contrast agent gadobutrol (GBCAs) in the skin using matrix-assisted laser desorption/ ionization mass spectrometry imaging. Results showed the chemical form of residual gadolinium being intact Gd-chelate. No indications for dechelation of free gadolinium were observed. Gadobutrol levels in the skin were low and almost at the level of detection within 5 weeks.

·         Gadolinium presence in bones: Evaluation of the novel, high relaxivity gadolinium-based contrast agents gadoquatrane and gadopiclenol

This study focuses on the presence, dose-dependency, and distribution of Gd in the rat femur after administration of gadoquatrane and gadopiclenol – novel, macrocyclic GBCAs. The established macrocyclic GBCA gadobutrol serves as a standard of reference.
After receiving an equal dose of Gd, the concentration in rat femurs one week post-injection was 50% lower for gadoquatrane compared to gadobutrol. Gadopiclenol led to the highest Gd levels in the femur, showing a 5-fold increase over gadoquatrane and a 1.9-fold increase over gadobutrol.

·         Comparison of physico-chemical properties of the novel, high relaxivity, macrocyclic gadolinium-based contrast agents, gadoquatrane and gadopiclenol

A first assessment of the physico-chemical properties of both contrast agents gadoquatrane and gadopiclenol, regarding r1-relaxivity and complex stability, is presented. This study compared the physico-chemical properties of the new MRI contrast agents gadopiclenol and gadoquatrane, finding both have r1 relaxivities over twice that of gadobutrol, influenced by human plasma variability. The gadolinium release in blood plasma was below the lower limit of quantification for gadoquatrane, while gadopiclenol showed an observable gadolinium release over 15 days. Gadoquatrane's stability is further highlighted by its slower Gd3+ (Gadolinium) release at low pH compared to gadopiclenol.

·         Assessment of Pharmacokinetics and Safety of Gadoquatrane in Renally Impaired Patients and its Dialyzability Using Clinical Trial Data, Modeling & Simulation Approaches and in-vitro Data.

This study focused on the pharmacokinetics and safety of gadoquatrane in renally impaired patients, using clinical trial data with modeling and simulation approaches and in vitro testing for dialyzability assessment, leveraging the broad knowledge of the class of GBCAs avoiding exposure of vulnerable patient populations, i.e. with severe renal impairment, in clinical trials.

·         Gadobutrol: Review of over 25 Years of Use Exceeding 100 Million Administrations

Gadobutrol has been administered over the last 25 years more than 100 million times worldwide. Purpose of two literature-based review papers that will be presented as Electronic Poster Sessions (EPOS) at ECR, was to perform a thorough review and status update on gadobutrol’s clinical safety as well as its efficacy in nine approved indications and use in children. Once again it could be confirmed that the numerous clinical studies in a broad range of indications document the long-term experience and well-established benefit-risk profile in any approved indication and populations with gadobutrol. The evaluated body of evidence focusing on efficacy, including 65 studies with 7,806 patients, thereof 271 children, showed that gadobutrol is an efficacious MRI contrast agent for all age groups in various approved indications throughout the whole body.

Launch of Bayer’s Medical Imaging Core Lab Services

For the first time, Bayer is also presenting its Medical Imaging Core Lab Services at ECR. Half of all ongoing clinical trials across the industry today, and 90% of oncology trials, use medical imaging as an essential means of evaluating the safety and efficacy of investigational medicines, and in supporting the overall conclusions of a study.

Over the past decade, the number of clinical trials utilizing medical imaging has increased by 500%. Next to medical imaging services to clinical trials, the integrated service provides end-to-end imaging core lab solutions, scientific consulting, cloud-based image acquisition, quality control, evaluation and management as well as real-time operational and quality metrics. Its network of over 40 core experts, and more than 100 additional internal and external associated physicians and radiologists, is currently involved in more than 50 clinical trials from Bayer and its platform companies as well as internal developments of Software as Medical Device (SaMD). With the official launch at ECR 2024, Bayer’s Imaging Core Lab Services will be made available to external customers.

About Bayer’s clinical development program for gadoquatrane
Bayer, a global leader in radiology, started the Phase III clinical development program QUANTI in June 2023, aiming to evaluate the efficacy and safety of gadoquatrane, a next-generation, extracellular, macrocyclic, gadolinium-based contrast agent (GBCA) for use in magnetic resonance imaging (MRI). Gadoquatrane is a highly stable MRI contrast agent featuring high relaxivity that has the potential to enable a substantially lower gadolinium (Gd) dose for patients undergoing a contrast-enhanced MRI.

The QUANTI clinical development program encompasses two multinational Phase III studies, QUANTI CNS (central nervous system) and QUANTI OBR (other body regions), as well as one pediatric study, all investigating gadoquatrane at a dose of 0.04 mmol Gd/kg body weight (BW). This represents a gadolinium dose reduced by 60 percent in contrast-enhanced MRI compared to standard dosing (0.1 mmol Gd/kg BW) of established macrocyclic GBCAs, which, if successfully tested, would constitute the lowest gadolinium dose for a multipurpose MRI contrast agent.

Contrast-enhanced MRI plays a key role in the healthcare continuum, providing a radiation-free, non-invasive method of obtaining detailed images of the body, helping to distinguish and identify potential abnormalities within organs and tissues and supporting physicians in answering critical medical questions in the detection, characterization, and monitoring of disease.

About AI in Radiology
The overall global medical imaging AI field, with sales of more than USD 500 million in 2022, is expected to continue growing dynamically. With an estimated compounded annual growth rate of 25 percent, the market is forecast to reach USD 1.7 billion by 2027. Innovation powered by AI is needed more than ever. Aging populations and changing lifestyles are leading to an increase in chronic conditions, such as cardiovascular disease and cancer. Consequently, the demand for medical imaging to detect diseases, guide treatment decisions and support therapy planning is growing. AI comes with the value proposition of aiding diagnosis and increasing the throughput of radiological examinations.

This is particularly important because time pressure and workload are contributing to the prevalence of burn-out among radiologists. This situation is aggravated by the fact that there is a shortage of trained radiologists. In addition, publications show that the rate of diagnostic errors rise with long hours of overtime; a publication from 2018 mentions approximately 40 million diagnostic errors annually worldwide, involving imaging. Digital technologies can help manage the mounting workload of radiologists and their teams, with the ultimate aim of improving patient care.
