NEW NONINVASIVE METER
Technical Chemicals & Products, Inc. (TCPI),
a Florida-based maker of diagnostic testing and health screening products, has begun final
clinical trials of its new "TD Glucose" noninvasive glucose monitor. External
studies and preliminary clinicals "have shown efficacy and substantial correlation
(98%+) of the TD Glucose System with current finger-stick glucose tests," say company
documents.
A "noninvasive" glucose meter, the TD
Glucose System does not require the user to pierce the skin with a lancet, or in any way
draw a blood sample. The user places a small, chemically-treated patch on the forearm for
about five minutes, then the meter is held up to the patch (no wires to plug in), which it
optically scans, providing an immediate reading. The single-use patch is then removed and
discarded.
Although not yet free of the need to
"individually calibrate" meter to patient, TCPI states they have reduced the
interval to once every six months, and that it may be further reduced. The calibration is
meant to be performed by the patient's physician, and is described as "similar to a
glucose tolerance test." Once the test is completed, the physician enters the results
into his computer; company software then updates the patient's meter.
The unique part of the system is the patch; the
meter is very simple, and is scheduled to sell for about $100. Where the meter is unique
is in its optical scanning system (no wires), its 32-bit operating chip (like a Pentium
computer), and its provision for 720-test memory (90 days x 6 tests per day). The meter is
meant to be pocketable. It has proven durable, and it uses a 9-volt transistor battery,
available anywhere.
The company states their proprietary
glucose-sensing patch has already been found to be "in no way a biohazard;" no
specialized disposal techniques or procedures will be required. As no lancets are needed
either, look for a real reduction in dangerous waste.
As required by the calibration procedures
described above, the meter has a data-port for attaching to a computer. The patient will
be able to download test data as well. Not only may this data-port allow future use of a
voice synthesizer, the company has expressed interest in possibly including an onboard
voice chip in a "second generation" of the meter.
TCPI, which will manufacture both meter and
disposable patches, will supply them to its "marketing partners," who will
handle distribution, publicity, and sales (and will have final authority over pricing).
Dai-Ichi Co., Ltd., of Japan, will handle Asian sales; American "partnership"
negotiations are pending.
The company intends to submit its test findings
to the FDA in late 1999. Stay tuned.
