Lumoral's journey from a brilliant idea to a unique oral health medical device

Lumoral's journey from a brilliant idea to a unique oral health medical device

Koite Health Oy is a Finnish health technology company that develops light-activated antibacterial solutions for the treatment and prevention of oral diseases. The company’s Lumoral teeth cleaning method can be used at home by children and adults to prevent tooth decay and gum diseases and treat even the most severe cases of gum disease including periodontitis.

Mikko Kylmänen, Clinical Research Project Manager at Koite Health, explains the importance of high standard clinical research and the different stages that took place before the innovative Lumoral method for oral self-care became available to consumers.

Why is clinical research needed?

Clinical research is needed to ensure that healthcare devices on the market are safe to use, are fit for their intended purpose and meet the characteristics and performance standards required. When clinical trials are conducted to a high standard and based on scientific evaluation, both users and healthcare professionals can have confidence in the quality and performance of the medical device.

The development of medical technologies is based on multidisciplinary research, which continues actively even after the product has been launched on the market. The effect of regular use of Lumoral has been – and still is – the subject of multiple clinical trials, for example, in the treatment of dental implant-related infections. The results have been promising: plaque amount and gum bleeding around the inflamed gum tissues of patients were significantly reduced compared to the initial situation. More research on this topic is expected to be released later in 2023. 

In December 2022, Koite Health published the interim report of a large periodontal study in an international dental journal

– The findings were so significant that we wanted to bring them to the attention of the professional and scientific communities, and also Lumoral users as soon as possible. At the same time, seeing these results gave us at Koite Health more information about the performance and safety of the device. The new information also can be used when new studies are planned, Mikko Kylmänen concludes.

Standards are the basis for clinical research

According to Kylmänen, international standards are the cornerstone of clinical trial designs for Lumoral. These include ISO 14155 GCP (Clinical Trials on Medical Devices - Good Clinical Practice) and the European Union's Medical Device Regulation EU 2017/745 (MDR). 

A Lumoral clinical trial must have clear goals and objectives, either to ensure the effects of the treatment as already authorised, or to find new uses for Lumoral. Strict compliance with regulations will ensure that the safety of the study subjects is not compromised. 

– As a rule, our studies are randomised controlled trials between two study groups - the Lumoral group and the control group. Participants in both study groups will undergo exactly the same clinical measurements and will be given exactly the same self-care instructions. The only difference between the two groups is that one group uses Lumoral during the study and the other does not.

Randomisation means that the study group for a subject is randomly selected and neither the subject nor the researcher knows which group the subject belongs to before the study starts.

The company has sometimes been asked why it does not conduct placebo-controlled trials with Lumoral. According to Mr Kylmänen, it is quite common internationally that in device studies, subjects in one group have the device and not the other. Placebo-controlled studies are better suited to medical trials.

Brainstorming of studies is a collaborative process 

The best ideas for studies often come from open discussion with professionals such as dentists, oral hygienists or researchers. These discussions gradually lead to the development of a research outline, which is then refined by researchers in collaboration with the professionals involved in the individual study.

According to Kylmänen, involving professionals in Lumoral studies at an early stage is crucial because they know best the needs of their own speciality.  

– We always try to take into account the typical treatment frequency of the respective disease at the clinic. When planning this way, there is as little extra effort as possible for the study subjects.

Careful preparation is required to obtain authorisation for studies

All study plans for Lumoral studies  including the materials to be provided to subjects and the documentation related to data protection - are subject to an application to a research ethics committee for an opinion. As a rule, the committee is selected according to where the study will be conducted. Issues such as data protection are also carefully considered at this stage. 

When the committee finally gives its opinion, it is the turn of the Finnish Medicines Agency (Fimea), or equivalent authority in other countries, to give approval to start the clinical study. Fimea's tasks include the supervision of medical devices in Finland under the MDR Regulation. Clinical trials of devices are also subject to supervision.

– If Fimea requires changes to the study plan, the changes must be resubmitted to the Ethics Committee, either as a new application or as a notification. Overall, the application process for regulatory approvals in Finland takes at least three months. Usually even longer. After that, approvals are still needed from the clinics where the research will be carried out.

Contracts are concluded according to need and local practice

Various contracts can be concluded with researchers and clinics, depending on need and local practice. Often a local research authorisation also requires a research contract to be drawn up. 

– We also take care of the costs of the sponsored studies, and these are written into the contracts. We also have contracts with so-called CROs (contract research organisations), from whom we buy research monitoring services, says Kylmänen.  

Good clinical practices guide Lumoral studies

One of the most important principles of clinical research is that no measurement or procedure related to the study should be performed on any patient without their written consent. 

According to Kylmänen, good clinical practice in Lumoral trials also includes training and ensuring the competence of the research team and providing background support for researchers throughout the trial. The MDR regulation, on the other hand, requires close monitoring of the benefits and potential harms of the device. 

– Of course, this is also in our interests from the point of view of the device developer, Kylmänen stresses.

Quality control is an important part of clinical research

For each trial, an individual quality control or monitoring plan is drawn up. This covers among other things, the consent collection process, and recording and reporting of adverse events. It also covers the review of trial data before the trial results are analyzed. 

Monitoring is one of the most important steps in the overall safety and scientific credibility of a clinical trial, according to Kylmänen.

Clinical research is like a marathon

Kylmänen points out that science is complex. Even if "your own thing" may seem clear to you, you may have to explain it in great detail to other scientists even co-scientists.

 Even the most thorough explanation does not necessarily guarantee that everyone will believe you. Research results come slowly. If a study starts today, it could be two or more years before it reaches the publication stage. In fact, I now think of a clinical trial as more than just a single marathon. It is a series of marathons. Like running in slightly different landscapes repeatedly. And even if you reach one goal, there may be several journeys yet to be completed and new ones to meet.

– However, I must add that the launch of Lumoral to the market did not happen by chance. The idea to develop an antibacterial teeth cleaning Lumoral method was based on scientific evidence from the outset. It took three years from the initial concept to the launch of the current product. Now the final product  is unlike anything we have ever seen before. Helping to bring clinic-level treatment to a relatively hassle-free home-based treatment. Without compromising on quality.

 

Koite Health to showcase its Lumoral innovation at the Igienista Dentale 3.0 congress for dental hygienists in Italy

Koite Health to showcase its Lumoral innovation at the Igienista Dentale 3.0 congress for dental hygienists in Italy

Finnish health technology group Koite Health will participate in the upcoming third edition of the Igienista Dentale 3.0 (Dental Hygienist 3.0) congress on March 4, 2023, in Rome, Italy. The now sold-out congress will return to the prestigious venue of the Tor Vergata University in Rome after a break since 2020 due to the COVID pandemic.

The Igienista Dentale 3.0 event is focused primarily on dental hygiene professionals. The congress comes only shortly before Germany's IDS Cologne event where Koite Health will also showcase its Lumoral-method – an innovative technology designed to enhance oral home care for the prevention and treatment of gum diseases and dental caries.

– Our goal is to increase the visibility of the Lumoral brand and identify potential commercial partners, says Koite Health's Chief Commercial Officer Tero Pasanen.

– Italy is an important market for Lumoral. We aim to expand to some of the largest nations in the European Union as fast as possible. This way we can offer our European customers access to better oral hygiene. Through our expansion we seek to give patients who suffer from periodontitis a chance to stop the progression of the disease and to help tackle the ever-growing problem of peri-implantitis, Pasanen adds.

Lumoral will be represented at the Italian event by Italian dental hygienist professional Gianfranco Panzironi.

Panzironi has written a scientific paper titled "Home photodynamic therapy as a means of prevention for biofilm control" that explores the role of dental plaque in causing oral problems and the benefits of Lumoral in prevention of oral problems.

– Prevention is the pillar against oral diseases and compliance with correct oral hygiene techniques is essential to preserve the normal microbiome and maintain the health of the oral cavity. Among the new technologies that allow the patient to control the biofilm comfortably and effectively, a device for the home application of antibacterial photodynamic therapy stands out.

Lumoral is a cutting-edge medical device that is designed to improve oral hygiene and significantly improve oral health. Lumoral offers anti-inflammatory treatment for various groups of patients – even those with difficult-to-treat oral conditions such as severe gum disease, and periodontitis. Lumoral is scientifically proven to be the best available home care treatment for periodontal patients and implant maintenance.

IDS 2023 will be organised from 14 to 18 of March in Messe Cologne. Koite Health recently signed a distribution agreement with white cross GmbH, a German distribution and training company specializing in oral health prevention. Following the agreement white cross will focus its marketing efforts on over 55.000 dentistry professionals in the German market to promote the use of Lumoral.

Study identifies potential link between oral bacteria and brain abscesses

Study identifies potential link between oral bacteria and brain abscesses

A study led by researchers from the University of Plymouth and University Hospitals Plymouth NHS Trust in the UK shows that bacteria known to cause oral infections may also be a contributory factor in patients developing potentially life-threatening abscesses on the brain.

The study, published in the Journal of Dentistry, investigated brain abscesses and their association with bacteria that occur in the oral cavity. While this type of abscess is relatively uncommon, it can result in significant mortality and morbidity.

The study examined the records of 87 hospitalised patients with brain abscesses. Through analysing samples of the abscesses and peripheral cultures, they collected microbiological data.

Researchers found that the 52 patients who had no diagnosable cause for their abscess, were three times more likely to have oral bacteria present.

In particular, the team noted the presence of Streptococcus anginosus. This bacteria can lead to “pharyngitis, bacteremia, and infections in internal organs such as the brain, lung, and liver. This bacteria is often found in dental abscesses.” Writing in the study, researchers say the findings suggest that the oral cavity could be considered a source of infection in cases of brain abscess where no clear cause has been identified.

- While many potential causes of brain abscesses are recognised, the origin of infection often remains clinically unidentified. However, it was still surprising to frequently find orally occurring bacteria in brain abscesses of unexplained origin. It highlights the importance of using more sensitive techniques to assess the oral cavity as a potential bacterial source in brain abscess patients. It also highlights the importance of improving dental care and oral hygiene more generally, Dr Holly Roy, the studies lead author tells EurekaAlert!

Ongoing research is taking place within the university’s Oral Microbiome Research Group to examine the link between oral microbes and a variety of cardiovascular and neurological conditions.

The study forms part of ongoing research taking place within the University’s Oral Microbiome Research Group, led by Dr Raul Bescos and Dr Zoe Brookes, to explore the links between the oral microbiome and a range of cardiovascular and neurological conditions.

Other clinical trials are underway investigating the links between gum health and Alzheimer’s disease and identifying patients under high cardiovascular risk in primary care dental clinics, as an altered balance of oral bacteria (microbiome) during gum disease can lead to high blood pressure and strokes.

These clinical studies are being carried out in primary care dental facilities run by Peninsula Dental Social Enterprise, where the focus of the research is very much on improving clinical outcomes for patients.
