Senseonics (SENS) Path To Glory and Its Potential To Secure Dominance and Revolutionize Diabetes Care

Senseonics (SENS) is a medical device company that manufactures patented implantable continuous glucose monitoring devices. This device is surgically placed underneath the skin and is the world’s first and only long-term continuous glucose monitoring system.

It has the ability to provide real time feedback of blood glucose levels with the sensor that is subcutaneously implanted into the upper arm region. The sensor will then send that information to an adhesive transmitter that is placed anterior to the patient’s implanted sensor. Shortly after blood glucose data is delivered, the transmitter will send important information regarding blood glucose levels to the patient’s mobile device and will also provide vibratory on body alerts if the patient does not have the mobile device nearby.

The mobile application that comes with this device is able to receive real time glucose measurements so there is no need for a separate receiver that other products in the market require. Patients can share data with friends, family, and even their Health Care providers. Senseonics aims to disrupt the CGM market in partnership with Ascensia Diabetes Care, one of the top diabetes companies in the world.

As you all can see Senseonics has an immensely strong team under their belt with leaders that specialize in a plethora of different areas. They all have impeccable track records and are striving to develop and distribute a product that will revolutionize how diabetes is treated going into the future. Now that we have all that boring but essential stuff out of the way… Let us move on to the accuracy of the Eversense Technology compared to their competitors and what makes their product stand out.

Accuracy of the Eversense Technology

On June 3rd 2023, Senseonics released the PROMISE study results which evaluated the accuracy of the next generation Eversense continuous glucose monitoring system for the 180 day system with reduced calibrations. This data was presented by Satish Garg, MD, Professor of Medicine at the Barbara Davis Center of the University of Colorado, Denver, and the study group Principal Investigator (PI). The study results presented show the Overall mean absolute relative difference (MARD) against reference value was 9.1% for the primary sensor over 49,000 paired points and 8.5% for the SBA sensor over 12,000 paired points. Typically a CGM system with a MARD <10% is regarded to have good analytical performance. Confirmed hypoglycemic alert detection rate was 93% for primary sensor and 94% for the SBA sensor. There were no related serious adverse events, all sensors were removed during the initial removal procedure and 1.1% of patients had a mild infection at the procedure site. The results presented in the PROMISE study demonstrated an excellent safety and accuracy profile for the 180-day sensor.

Accuracy of Eversense Technology Compared Competitors

Among adults with type 1 diabetes concurrently wearing three continuous glucose monitoring devices, accuracy of the devices was lower than reported in clinical studies, according to a speaker here. Researchers found the Senseonics Eversense implantable CGM to be more accurate than the Dexcom G5 and the Abbott Freestyle Libre Pro, the professional version of the CGM, devices.“It should be noted that the Eversense and the G5 were calibrated twice daily, and the Libre Pro is designed not to allow calibrations,” Rabab Z. Jafri, MD, a fellow in endocrinology at Massachusetts General Hospital, told Endocrine Today.

Jafri and colleagues assessed the accuracy of the three systems used by 23 participants as part of a 6-week, free-living, outpatient bionic pancreas study. Researchers compared the glucose measurements obtained with the Nova Biomedical StatStrip Xpress meter, which was used to calibrate the Eversense and G5 devices, with readings from all three CGMs when they were recorded within 5 minutes of the meter readings (n = 829 sets) and also compared a greater number of readings between the G5 and Eversense (n = 2,277 sets). The primary outcome was mean absolute relative difference. Lower mean absolute relative difference indicates greater accuracy.

Among the three systems, the Eversense had the lowest mean absolute relative difference at 14.8%, with the G5 (16.3%) and the Libre Pro (18%) higher (P = .004). The Eversense again had a lower mean absolute relative difference than the G5 in a comparison between the two (15.1% vs. 16.9%; P = .008).

This data suggests that the Senseonics Eversense is likewise sufficiently accurate to provide the input to the bionic pancreas devices in future studies. Not only is the implantable CGM produced by Senseonics is just as accurate as their competitors if not even more accurate; the Eversense technology also garners the ability to last much longer and currently only requires 2 calibrations a day for accuracy. They are working on bringing once a week calibrations for the 365 day device that is in their pipeline for products produced and distributed in the future.

Partnership With Ascensia Diabetes Care

On August 10th, 2020, the company announced a strategic collaboration with Ascensia Diabetes Care. This is a transformational alliance for Senseonics, as Ascensia is a dedicated diabetes company with a presence in 125 countries and 10 MM customers. It has the trust and reliability of being in this business for over 70 years. Ascensia is the market leader in the Blood Glucose Monitoring (BGM) market with its COUNTOUR portfolio of devices and it is the combination of several important companies with interests in the Diabetes market. Ascensia is based in Switzerland and it was established in 2016 through the acquisition of Bayer Diabetes Care by PHC Holdings (formerly known as Panasonic Healthcare Holdings), which is a KKR portfolio company. Ascensia Diabetes Care is betting big on Senseonics. Not only are they providing 35 MM in convertible debt financing but will also invest an approximate $250 MM over the next five years to commercialize and market Eversense in exclusivity all over the world. So why would such a company with approximately $1 Billion in annual sales be interested in a $4 MM revenue company? Ascensia’s business is CONTOUR, a razor/razor blade business model in which the company sells blood glucose measuring devices for a low price and makes money selling the small lancets that are replaceable. Consumers looking through Amazon or simply Google “Blood glucose monitoring” will find that this market is oversaturated with dozens of suppliers competing in price. Ascensia prices its wares at a premium over competitors but the technology is mature so it is unknown if new diabetes clients will be choosing Contour going forward. Basically, they need a new product that can reinvigorate the brand and put them once again at the leading edge of the diabetes market. This is where Senseonics comes in.

Currently the Senseonics Eversense device requires calibration twice a day, that could be done using a Contour device to measure the glucose level and input the result in the Eversense device via an iPhone or Android Phone. But as the above figure shows, the company has a product pipeline with next generation devices that will require increasingly less calibration. The Eversense XL submitted for approval to the FDA requires only one calibration a day and the Eversense 365 will require only one rebalancing a week, reducing considerably the use of lancets for blood monitoring systems. Ultimately, this is a product and company that Ascencia values greatly and is working to make sure they survive as its a product that can immensely bolster their portfolio for incoming consumers.

Future Growth Expectations and Sensonics Potential of Disrupting the Current CGM Market

The technology has huge potential to disrupt the current CGM market, which is a $5-plus billion market today growing at about a 35% CAGR (according to SENS management) and dominated by three large companies: DexCom (DXCM), Abbott Labs (ABT) and Medtronic (MDT). This market is exclusively focused on the Type 1 and Type 2 diabetes patients which are intensively managed, that means they require insulin shots and many diabetes patients use insulin pumps since they are unable to produce any insulin themselves. The number of people with diagnosed diabetes in the USA in 2020 was 34.2 of which 1.6 MM have Type I Diabetes, unfortunately the number of people with Diabetes is growing at an immensely rapid pace as shown from this National Diabetes Statistics Report, 2020.

With FDA approval for the Eversense XL expected by the end of the third quarter, Senseonics will start to eat at the market share of the incumbent companies in the industry, but the real game changer will come with the Eversense 365, as it will open up the Type II market to this new type of CGM devices. Here the opportunity is really huge and they face no competition and none is expected anytime soon either as their product is already patented. Currently, people with Type II diabetes have only BGM devices like CONTOUR or Dexcom’s products to help them monitor their blood levels, but that requires pricking a finger to get blood and only provides a measurement at that particular moment. The 365 device will require only a 5 minute intervention every year to remove and replace the sensor and if the company gets to the point that won’t need a transmitter, as patients scan your smartphone over the sensor.


Senseonics is a high risk/high reward type of investment as current valuations of the stock are actually overpriced. They have not produced any notable revenue thus far. However they are working at a very accelerated pace to get their product out into the US and are already selling in Europe. There is a small chance that the company will file for insolvency anytime soon and with the Ascencia alliance it stands a very good shot at disrupting the diabetes market. Senseonics has the makings of a potential multibagger and the next catalysts for the company will be information of progress in the commercialization in Europe and from April 1st in the USA, then it will be the Eversense XL approval by the end of September.
