Company Profile:
Genetronics Biomedical Corporation is a drug delivery company. They specialize in
developing technology and hardware, which potentially will allow physicians more
efficiently and cost-effectively to deliver life-saving drugs or beneficial genes to
patients with catastrophic illnesses, including cancer. Genetronics is the technology
leader in electroporation, the application of very brief, carefully controlled, pulsed,
rotating electric fields to human cells, a process that causes pores to open in the cell
membrane and allows pharmaceuticals or genes to gain access to the cells interior.
The therapy allows chemotherapeutic drugs (drugs that otherwise cannot enter the cell
effectively) to accumulate inside the cell at relatively high concentrations and kill the
cancerous cells. The amount of drug used per treatment is much lower than in conventional
chemotherapy.
Its proprietary Medpulser® delivers "square wave" pulses
which are more effective than "exponential decay" pulses for the electroporation
of cells in the human body. In addition, the Medpulser® is programmed to deliver pulses to
multi-needle electrode applicators in certain patterns and with different polarities to
maximize electroporation efficiency. The Medpulser® allows physicians treating oncology
patients with Electroporation Therapy to control the electric pulses with a foot pedal,
thus freeing the physicians hands to apply the electrode applicators to the tumor.
Electroporation is a broad-based technology, with many ways to achieve commercial success.
Genetronics is developing applications for this technology in the primary areas of
oncology and gene therapy. They have completed Phase I and Phase II clinical trials in the
United States for the treatment of head and neck cancer. The Company has a strong patent
portfolio of 216 patents approved or pending, a formidable barrier to competition.
In gene therapy, Genetronics has multiple collaborations with major biotechnology
and pharmaceutical companies for the use of electroporation for gene delivery. Genetronics
BTX® Division, a leader in molecular delivery, features electroporation and electrofusion
technology for research laboratory markets worldwide. Electroporation equipment has one of
the fastest growing markets of all laboratory products. It is used in experiments
involving animal cloning and gene therapy.
Genetronics, BTX instrument division now
offers seven electroporation and electrofusion instruments and more than 22 accessories
that are sold in 40 countries where over 2,000 universities and research laboratories
continue to use BTX products as an integral part of their research. Some of these BTX
instruments are multi-purpose, capable of accommodating a wide range of parameters to help
researchers conduct experiments in novel areas. Others are reliable laboratory
"work-horses," which help researchers achieve consistent, reproducible results.
Other applications for Genetronics electroporation therapy includes intradermal and
transdermal delivery of drugs, DNA or cosmetic substances. Programs include treatments to
combat pain, erectile dysfunction, skin damage and osteoporosis.
