Individuals with diabetes have to observe their blood sugar ranges often by pricking their pores and skin. Many glucose-monitoring machine makers worldwide are pursuing needle-free approaches to make this painful course of extra manageable. Amongst them is a South Korean firm known as HME Sq., which makes use of photoacoustics to check glucose ranges noninvasively.
HME Sq. was based in 2020 by Yoonho Khang, who beforehand labored in semiconductors at Samsung corporations for 20 years, and Sooah Im, a medical physician.
Khang tells TechCrunch that the co-founders needed to develop a tool to deal with this frequent well being subject and determined to construct a needle-free glucose monitor. Diabetes impacts greater than half a billion folks worldwide, which is predicted to improve to 1.3 billion by 2050.
HME Sq., a member of this 12 months’s Battlefield 200 at TechCrunch Disrupt, claims its preliminary examine reveals accuracy higher than steady glucose monitoring (CGM) gadgets available on the market. A preliminary examine shared with traders, primarily based on the imply absolute relative distinction (MARD) and the Clarke Error Grid (CEG), a device used to evaluate the accuracy of glucose screens, reveals its present MARD is 7%. (The decrease the MARD, the upper the accuracy.) CGM gadgets, similar to these from Abbott, Dexcom and Medtronic, present between 8.7% and 9.2%.
The corporate’s machine makes use of a MEMS sensor and photoacoustics utilizing deep studying to measure blood sugar, Khang mentioned. Photoacoustics is a noninvasive sensing method that entails shining mild on a substance (similar to blood) and studying the ultrasonic waves it emits.
The expertise additionally can be utilized for broader functions in varied organic substances within the physique, Khang notes. For instance, it will possibly monitor ketones, glycated hemoglobin (HbA1c), ldl cholesterol in section 2, and bilirubin and creatinine in section 3.
HME Sq. is within the R&D stage now, and it’ll take a pair extra years to deliver the machine to market in South Korea and the U.S., aiming for 2025, Khang mentioned. The startup plans to use good manufacturing practices (GMP) in Korea subsequent 12 months. GMP is a set of requirements that ensures pharma merchandise are persistently produced. After getting GMP approval, it should begin scientific trials within the nation, which can take round a 12 months, Khang provides.
Not like invasive measures similar to blood sampling or CGM, which may simply set a reference level as a result of samples are collected straight, Khang explains that with noninvasive glucose monitoring, it’s not simple to get correct outcomes or knowledge.
“For instance, the optical technique expertise utilized by Apple obtains loads of knowledge, however as a result of it can not straight examine alerts from totally different wavelengths, it’s difficult to enhance measurement accuracy. We’re centered on fixing this drawback, and we’re at the moment making important progress.”
Khang claims their photoacoustic technique is superior as a result of photoacoustic ultrasonic alerts are comprised of glucose-absorbed power from laser and comprise extra info, although a latest report says, “Among the many non-invasive glucose monitoring methods, the optical strategies give the perfect measurements. Optical applied sciences similar to near-infrared, mid-infrared, or Raman spectroscopy have nice selectivity for glucose sensing given the complexity of the blood/tissue properties.”
The corporate will use a direct-to-consumer enterprise mannequin, promoting merchandise to folks with diabetes and individuals who use invasive measures like CGM. The outfit can also be contemplating including subscription fashions as soon as it commercializes, Khang says, including that its machine will possible price round $1,000 for 2 years of use.
Since its inception, the corporate has raised greater than $3 million from traders, together with Postech Holdings. HME Sq. is within the technique of elevating $2 million for R&D and hiring further employees.
