Successful human tests for first wirelessly controlled drug-delivery chip
Date:2/16/2012

(Cambridge, MA) About 15 years ago, MIT professors Robert Langer and Michael Cima had the idea to develop a programmable, wirelessly controlled microchip that would deliver drugs after implantation in a patient's body. This week, the MIT researchers and scientists from MicroCHIPS Inc. reported that they have successfully used such a chip to administer daily doses of an osteoporosis drug normally given by injection.

The results, published in the Feb. 16 online edition of Science Translational Medicine, represent the first successful test of such a device and could help usher in a new era of telemedicine delivering health care over a distance, Langer says.

"You could literally have a pharmacy on a chip," says Langer, the David H. Koch Institute Professor at MIT. "You can do remote control delivery, you can do pulsatile drug delivery, and you can deliver multiple drugs."

In the new study, funded and overseen by MicroCHIPS, scientists used the programmable implants to deliver an osteoporosis drug called teriparatide to seven women aged 65 to 70. The study found that the device delivered dosages comparable to injections, and there were no adverse side effects.

These programmable chips could dramatically change treatment not only for osteoporosis, but also for many other diseases, including cancer and multiple sclerosis. "Patients with chronic diseases, regular pain-management needs or other conditions that require frequent or daily injections could benefit from this technology," says Robert Farra, president and chief operating officer at MicroCHIPS and lead author of the paper.

"Compliance is very important in a lot of drug regimens, and it can be very difficult to get patients to accept a drug regimen where they have to give themselves injections," says Cima, the David H. Koch Professor of Engineering at MIT. "This avoids the compliance issue completely, and points to a future where you have fully automated dru
