As innovations in digital capabilities continue to be used with various health care products, Proteus Digital Health, Inc. is developing a suite of what it terms digital medicines. And while the company has been working on such products for a few years, it recently came out with the first such product within the oncology space, AIS Health reported.

Proteus is partnering with Fairview Health Services and the University of Minnesota Health to offer oral capecitabine combined with an ingestible sensor to treat stage 3 and stage 4 colorectal cancer patients.

David Purdie, vice president of medical affairs at Proteus, explains that through an open capsulation process, a pharmacist will place a capecitabine pill and a sensor within a capsule and then seal it. The capsule dissolves within a person’s stomach within a minute or so after it’s ingested. “Each sensor has a unique identifier,” and after the capsule dissolves, an app on a mobile device transmits data such as the time of the dose, the medication taken, the dosage of the drug and certain patient reactions to the drug to the cloud, where the information matches up with a database. “Every pill is uniquely identified,” so if someone takes 30 different pills at one time, the database will be able to know exactly what each medication is.

Asked how his company decided to launch the oncology program, Purdie replies, the main reason “is oncology traditionally has been an infused medication space.” But there’s been a huge increase in the number of FDA-approved oral oncology drugs since then, which allows patients to “medicate at home,” he notes.

“With oncology drugs, every patient is kind of different” in their response, Purdie explains. “It’s important that providers give enough drug so the disease is going to be killed but not enough that patients are so sick they cannot function.”

“With the increase in the number of oral chemotherapy agents being approved and utilized in cancer care, adherence needs to be a key focus for the patient and care team,” says Darcy Malard Johnson, Pharm.D., oncology pharmacy program manager at Fairview and University of Minnesota Health Cancer Care. “Oral chemotherapy puts more accountability onto the patient. A device like this gives both the patient and the care team insight into patient adherence by providing a clear picture of how the medication is being taken. By understanding patient-specific adherence, we can help the patient manage adherence for the best possible clinical outcome.”
