“We are laying the foundation for innovative therapies in diabetes.”

Maria Luisa Balmer has been an assistant professor at the Universität Bern and University Hospital of Bern and at the DCB (Diabetes Center Berne) since 2021. Together with her team, she researches the complex pathologically altered bodily functions (pathophysiology) and connections between the intestinal flora, metabolism and inflammation.

Prof. Dr. Balmer, what is your research about?

We want to understand in more detail how the gut microbiota contributes to people becoming obese, or not. The gut microbiota refers to a group of tiny organisms, mainly bacteria, that live in our gut and play an important role in digestion and health. We are interested in the following questions: Which bacteria are beneficial? Which ones are more likely to contribute to the development of obesity (severe overweight, from body mass index 30) and the associated complications such as diabetes or liver disease? And why is this so? Are there certain metabolic products with which the intestinal bacteria influence our metabolism? These are all questions that occupy us in the team and which we approach in very different ways.

What motivates you to work in the field of obesity and diabetes?

Obesity and type 2 diabetes have become a pandemic that is spreading ever faster. Whereas in the past it was mainly the industrialised nations that were affected, today it is also affecting countries that previously had to struggle with the opposite, namely malnutrition and underweight. I am also concerned that more and more children and adolescents are affected by obesity. Despite many efforts in the area of prevention and therapy, there are more and more overweight people, with the corresponding health consequences.

What is your biggest challenge as a professor?

As a researcher, doctor and mother of two children, my everyday life is incredibly varied, diverse and occasionally a little chaotic. I find the balancing act between all my different activities very challenging, but at the same time enriching. Die biggest challenge is probably not to miss out myself.

What goals do you want to achieve with your team and your laboratory, the TrIm-Lab (Translational Immunometabolism Lab)?

My goal with my research is to contribute to a better understanding of the mechanistic connections between the gut microbiota and the development of obesity and metabolic complications, and thus to gain new approaches to prevention and therapy. At the same time, it is important to me to be a role model for the next generation of young scientists and to show that becoming a professor is a realistic goal, even for people who have other priorities in life, such as a family.

What projects are you currently researching and how can they make life easier for people with diabetes?

Our research is incredibly broad – from mouse experiments to clinical trials. For example, we work with mice in which we can precisely control the composition of the intestinal bacteria and thus find out which bacteria contribute to the development of obesity. On the other hand, we are currently running a clinical trial called FibreGum with obese children and adolescents, in which we are testing a special chewing gum that contains dietary fibres. We hope that this will have a favourable influence on the composition of the intestinal microbiota and that we will be able to support the children in losing weight in a low-threshold way.

How do you work with the DCB?

My research laboratory and my office are located at the DCB and I very much appreciate the fruitful collaboration. In addition to the infrastructure, the DCB also actively supports us in conducting clinical trials. The familiar and friendly environment is inspiring and a prerequisite for successful research.

Where do you hope your field of research will be in 5-10 years? What is your vision?

I hope that we will understand more precisely how bacterial metabolism integrates with human metabolism and that this knowledge will benefit our patients in a personalised form. My vision is to fight diseases like obesity and diabetes, not only in the rich industrialised nations, but worldwide.

You recently received the Marie Heim-Vöglin Prize, awarded by the Swiss National Science Foundation (SNSF). What pleased you most about this award?

For me, this prize is primarily a huge recognition, which of course makes me incredibly happy. It is wonderful that my research has met with such broad interest and that it has now found its way into the public eye through this prize. The response has been incredible and has touched me very much. I hope that this will motivate many young researchers to continue on their path. I will also continue my efforts to contribute to the fight against diseases such as obesity and diabetes.

Patient and public involvement is defined as “research done with or by patients and the public, not to, about or for them. It is about working collaboratively with patients and the public and sharing decision-making” [1]. It is not only about engaging the public to focus on awareness, nor is it about having patients merely participate in clinical studies.

At DCB, we aim to involve people living with diabetes at every step of the way and in all our processes – whether that be in the mentoring of our annual DCB Open Innovation Challenge, in our clinical research studies or in other decision processes.

PPI offers various benefits for researchers and companies. Most importantly, people living with a condition often know best which topics from their life remain under-researched and under-represented. Especially for translational research, which focuses on transferring scientific research into innovative product development, it can also uncover unmet needs that still need solutions. Altogether, involving those living with a condition in research processes can result in more impact overall.

DCB Patient Leaders

As part of our efforts to involve the diabetes community in our decisions and activities, we established a board of DCB patient leaders roughly two years ago. Our patient leaders represent lived diabetes experience in different parts of the world – from Switzerland all the way to Singapore. We greatly value the voices of those living with diabetes and believe that all processes should involve those with lived experience. Because after all, research and product development is being done because of and for those living with diabetes! To make it truly user-centric and impactful, we need to properly involve those with a sound judgment and lived experience of it.

PPI Event at DCB

Just recently, we hosted an event for patient and public involvement at our premises in Berne. In cooperation with the University of Bern and the Department of Diabetes, Endocrinology, Nutritional Medicine and Metabolism (UDEM) at the University Hospital of Bern, we invited participants of our past research studies, people living with diabetes, researchers and the DCB team. Together, we all discussed past study outcomes as well as visions for future patient and public involvement.

We live and breathe patient and public involvement at DCB and we are always on the hunt for new innovative methods and activities. If you are interested or want to contribute your thoughts, please don’t hesitate to reach out and get involved with us!

Since the beginning of 2023, José García-Tirado has been a professor specialising in diabetes technology at the University Department of Diabetology, Endocrinology, Nutritional Medicine and Metabolism (UDEM) and at the DCB (Diabetes Center Berne). Together with his team, he is involved in the development of even more precise therapies such as closed-loop systems for people with diabetes and other metabolic diseases.

José, what is your research about?

In our research, we are investigating the effects of type 1 diabetes and how we can develop technological solutions to better manage glucose in the body. We use computer models to understand different aspects of metabolism. Part of our work involves developing automated systems that deliver insulin like a fully functioning pancreas. We test these ideas on the computer and in clinical trials to ultimately make them useful for people with diabetes.

What motivates you to work in the field of diabetes technology? How did you get involved in this topic?

I am an engineer, was diagnosed with type 1 diabetes myself 10 years ago and had to overcome some hurdles, like most people with this disease. Coincidentally, I was attending a conference on the subject a few months later when I had an “aha” moment. I realized that I needed to get involved with the topic and contribute to the advancement of the field.

This has inspired me to research better technologies for diabetes management. I find it exciting to turn complex ideas into practical solutions and help other people with diabetes.

What is your biggest challenge as a professor?

Being a professor nowadays takes most of your energy and thoughts every day. Balancing my passion and work with family/hobbies time proves to be very challenging. From the work perspective, being the leader of a research group demands constant planning, supervision of human resources, and progress evaluation. Making plans to work in this field also entails close collaboration with experienced medical doctors and knowing very well the regulatory pathways to working with human beings in an ethical and caring way.

Professor Dr. José García-Tirado. Assistant professor with tenure track in diabetes technology.

What goals do you want to achieve with your team and your lab, the PrecisionLab?

Our goal is to develop technologies that can better support people with type 1 diabetes. We not only want to manage blood sugar, but also reduce other health risks. To this end, we are investigating new therapies and developing intelligent algorithms for insulin pumps.

What projects are you currently researching and how can they make life easier for people with diabetes?

The first project deals with the construction of an algorithm deployment platform in collaboration with Universitat Politècnica de Valencia. Such a platform will allow us to test every AID (“automated insulin delivery”) design in a clinical setting.

The second project is the design and testing of the actual smart algorithm to modulate insulin from an insulin pump for people with type 1 diabetes. Such an algorithm will be deployed and tested in our algorithm deployment platform. To do so, we need to go through a rigorous regulatory process with Swiss Medic. After approval, we will test our algorithm on five (5) participants with T1D with real-life challenges.

The third project relates to the understanding and mathematical modeling of macronutrient (carbohydrates, fats, and proteins) absorption in the bloodstream and how different compositions of meals affect glucose absorption.

Where do you hope your research field will be in 5-10 years? What is your vision ?

In the next few years, diabetes management technologies will evolve, with better sensors and insulin preparations. There is even the possibility of developing implantable systems that are even more similar to a pancreas. Similarly, we need to develop more accessible technologies for people with type 1 diabetes, as current options are often expensive and unavailable in many countries.

All these advances can significantly improve the quality of life of people with diabetes.

Medical device regulatory affairs – a headache for start-ups?

Confronted with the complexity of the regulatory lanscape in the context of medical devices, first doubts could arise when realising an idea into a product,

Regulatory affairs in the context of medical device development refers to the process of ensuring that a medical device complies with all applicable regulations and standards set forth by regulatory authorities. It is a crucial aspect of bringing a medical device to market and maintaining its compliance throughout its lifecycle. For a startup in medical device development, understanding regulatory affairs is essential to navigate the complex landscape of regulations and ensure successful product development and market entry.

Here’s a breakdown of key elements involved:

• Regulatory Framework: What is needed for my medical devices in the target market?
• Classification: What is the classification of my medical device based on the intended use, the risk level and the impact on patient safety? The outcome determines the regulatory requirements and the conformity assessment process for my device
• Conformity Assessment; Identifying the applicable conformity assessment procedures
• Quality Management System (QMS); Implementation of a robust QMS to ensure compliance with regulatory requirements (my own or of a legal manufacturer)
• Clinical Trials; Defining if a clinical trial is needed and if so, to which extent
• Usability/Human Factors; Defining the inclusion of the target group into the development
• Regulatory Submissions; Preparing and submitting necessary documentation to regulatory authorities for approval or clearance to market my medical device
• Post-Market Compliance; Maintaining compliance through post-market surveillance activities

The highly experienced team at DCB is entangling the regulatory world for you. Are you looking for a specific answer or for assistance in developing your quality system according to ISO 13485? Or just a recommendation with whom to partner up? DCB’s support is tailormade according to your needs.
