TDS® - Liquid TransDermal Delivery System
A liquid system which enables rapid transmigration of therapeutic doses of up to large molecules
Mechanism of action
Transient disruption of skin barrier properties and engagement of physiology to actively transport medicaments.
Full description
TDS® is a liquid vehicle plus medicament system
applied directly to the skin, not requiring a patch or other
appliance. The medicament is delivered rapidly and in
sufficient doses to accomplish a therapeutic
outcome at one seventh to one tenth an equivalent oral
dose. TDS® has been employed to deliver molecules of
various sizes and HLB profiles, including molecules such as
morphine HCL, heretofore considered undeliverable
transdermally. The company has completed 15 trials of 12
various molecules including 3 successful human trials and
successful delivery of a hydrophobic peptide. With TDS® the
medicament traverses intact skin without a needle or
significant irritation. Doses are typically compounded into
one milliliter of the TDS® and measured with a metered
pump or unit dose package.
Clinical data has demonstrated that TDS® can be modified
for
sustained release, site-local applications or systemic
absorption. This system enables significant clinical and cost
advantages versus alternative drug delivery modalities and
has a broad array of potential applications and business
opportunities
Because of the high efficiency of the TDS® systems,
effective flux of drug exceeding 90%, concetrated or dilute
doses are enabled and consequently, titration of dosing
specific to the patient is feasible. This is of particular
interest
in hormonal and pediatric applications.
TransDermal Technologies Inc. has formed a research
collaboration with The William Harvey Institute at St.
Bartholomew's and the Royal London School of Medicine
and Dentistry and can facilitate pre-clinical and
clinical work on molecule applications. Research schedules
are currently being negotiated for several molecules and
development time lines are accelerated.
Development status
Phase I/II
Patent information
Filings in place from Summer 1998, PCT applications
complete and U.S. Nationalization issued U.S. Patent
6,444,234 in September 2002 and U.S. Patent 6,787,152 in
September 2004 for the process and method for analyzing
any particular medicament and creating an optimized TDS®
for the medicament from the data developed. Delivery of all
classes of medicaments is claimed. Additional technology
and use patents are now pending
Type of business relationship sought
TransDermal Technologies, Inc. is actively seeking
companies interested in applying the TDS® technology
to off-patent molecules, new compounds for which
transdermal delivery would accelerate development and
reduce costs and companies seeking to extend patent
franchises.
Typical transactions would include reimbursement for
development expenses, progress milestone payments
and royalties on product sales. TransDermal may retain
patents, but complete license of rights for products
or product categories are negotiable. TransDermal will
currently entertain proposals of limited options for
license rights to hold applications off the market.
The company is open to joint - venture transactions with
value-added development companies as well as
companies with existing sales and marketing forces.
