Developed by MIT researchers, Leuko’s system gives a noninvasive methodology for most cancers sufferers to observe their immune well being at dwelling. By utilizing gentle and AI, it detects essential white blood cell ranges with out blood samples. The system is poised to enhance chemotherapy administration and cut back infection-related hospitalizations.
Leuko, based by a analysis group at MIT, is giving medical doctors a noninvasive solution to monitor most cancers sufferers’ well being throughout chemotherapy — no blood exams wanted.
Chemotherapy and different remedies that take down most cancers cells may destroy sufferers’ immune cells. Yearly, that leads tens of hundreds of most cancers sufferers with weakened immune techniques to contract infections that may flip lethal if unmanaged.
Medical doctors should strike a steadiness between giving sufficient chemotherapy to eradicate most cancers whereas not giving a lot that the affected person’s white blood cell depend will get dangerously low, a situation often called neutropenia. It could possibly additionally go away sufferers socially remoted in between rounds of chemotherapy. At the moment, the one approach for medical doctors to observe their sufferers’ white blood cells is thru blood exams.
Improvements in Well being Expertise
Now Leuko is growing an at-home white blood cell monitor to present medical doctors a extra full view of their sufferers’ well being remotely. Moderately than drawing blood, the system makes use of gentle to look via the pores and skin on the prime of the fingernail, and synthetic intelligence to research and detect when white blood cells attain dangerously low ranges.
The expertise was first conceived of by researchers at MIT in 2015. Over the subsequent few years, they developed a prototype and carried out a small examine to validate their method. In the present day, Leuko’s gadgets have precisely detected low white blood cell counts in tons of of most cancers sufferers, all with out drawing a single drop of blood.

Private and Regulatory Developments
“We anticipate this to carry a transparent enchancment in the best way that sufferers are monitored and cared for within the outpatient setting,” says Leuko co-founder and CTO Ian Butterworth, a former analysis engineer in MIT’s Analysis Laboratory of Electronics. “I additionally assume there’s a extra private aspect of this for sufferers. These folks can really feel susceptible round different folks, and so they don’t at present have a lot they’ll do. That signifies that in the event that they need to see their grandkids or see household, they’re always questioning, ‘Am I at excessive threat?’”
The corporate has been working with the Meals and Drug Administration (FDA) over the past 4 years to design research confirming their system is correct and simple to make use of by untrained sufferers. Later this yr, they anticipate to start a pivotal examine that might be used to register for FDA approval.
Future Potential and Broader Purposes
As soon as the system turns into a longtime device for affected person monitoring, Leuko’s group believes it might additionally give medical doctors a brand new solution to optimize most cancers therapy.
“Among the physicians that we now have talked to are very excited as a result of they assume future variations of our product might be used to personalize the dose of chemotherapy given to every affected person,” says Leuko co-founder and CEO Carlos Castro-Gonzalez, a former postdoc at MIT. “If a affected person is just not turning into neutropenic, that might be an indication that you might enhance the dose. Then each therapy might be based mostly on how every affected person is individually reacting.”
Monitoring Immune Well being
Leuko co-founders Ian Butterworth, Carlos Castro-Gonzalez, Aurélien Bourquard, and Alvaro Sanchez-Ferro got here to MIT in 2013 as a part of the Madrid-MIT M+Imaginative and prescient Consortium, which was a collaboration between MIT and Madrid and is now a part of MIT linQ. This system introduced biomedical researchers from around the globe to MIT to work on translational tasks with establishments round Boston and Madrid.
This system, which was initially run out of MIT’s Analysis Laboratory of Electronics, challenged members to deal with big unmet wants in medication and linked them with MIT college members from throughout the Institute to construct options. Leuko’s founders additionally acquired assist from MIT’s entrepreneurial ecosystem, together with the Enterprise Mentoring Service, the Sandbox Innovation Fund, the Martin Belief Middle for Entrepreneurship, and the Deshpande Middle. After its MIT spinout, the corporate raised seed and collection A financing rounds led by Good Progress Capital and HTH VC.
“I didn’t even notice that entrepreneurship was a profession possibility for a PhD [like myself],” Castro-Gonzalez says. “I used to be considering that after the fellowship I’d apply for college positions. That was the profession path I had in thoughts, so I used to be very excited in regards to the focus at MIT on attempting to translate science into merchandise that individuals can profit from.”
Leuko’s founders knew folks with most cancers stood to profit essentially the most from a noninvasive white blood cell monitor. Except sufferers go to the hospital, they’ll at present monitor solely their temperature from dwelling. In the event that they present indicators of a fever, they’re suggested to go to the emergency room instantly.
“These infections occur fairly regularly,” Sanchez-Ferro says. “One in each six most cancers sufferers present process chemotherapy will develop an an infection the place their white blood cells are critically low. A few of these infections sadly finish in deaths for sufferers, which is especially horrible as a result of they’re because of the therapy quite than the illness. [Infections] additionally imply the chemotherapy will get interrupted, which will increase unfavourable scientific outcomes for sufferers.”
Leuko’s optical system works via imaging the capillaries, or small blood vessels, simply above the fingernail, that are extra seen and already utilized by medical doctors to evaluate different features of vascular well being. The corporate’s transportable system analyzes white blood cell exercise to detect critically low ranges for care groups.
In a examine of 44 sufferers in 2019, Leuko’s group confirmed the method was in a position to detect when white blood cell ranges dropped under a essential threshold, with minimal false positives. The group has since developed a product that one other, bigger examine confirmed unsupervised sufferers can use at dwelling to get immune data to medical doctors.
“We work utterly noninvasively, so you may carry out white blood cell measurements at dwelling and way more regularly than what’s potential right now,” Bourquard says. “The important thing facet of that is it permits medical doctors to determine sufferers whose immune techniques turn into so weak they’re at excessive threat of an infection. If medical doctors have that data, they’ll present preventative therapy within the type of antibiotics and progress elements. Analysis estimates that may get rid of 50 p.c of hospitalizations.”
Increasing Purposes
Leuko’s founders consider their system will assist physicians make extra knowledgeable care choices for sufferers. Additionally they consider the system holds promise for monitoring affected person well being throughout different circumstances.
“The long-term imaginative and prescient for the corporate is making this accessible to different affected person populations that may additionally profit from elevated monitoring of their immune system,” Castro-Gonzalez says. “That features sufferers with a number of sclerosis, autoimmune illnesses, organ transplants, and sufferers which might be rushed into the emergency room.”
Leuko’s group even sees a future the place their system might be used to observe different biomarkers within the blood.
“We consider this might be a platform expertise,” Castro-Gonzalez says. “We get these noninvasive movies of the blood flowing via the capillaries, so a part of the imaginative and prescient for the corporate is measuring different parameters within the blood past white blood cells, together with hemoglobin, purple blood cells, and platelets. That’s all a part of our roadmap for the long run.”
