Inovio Biomedical: Tumor Ablation Technology Tempting to Big Pharmas

by Andrew Vaino



Inovio Biomedical (INO) is a small San Diego company seeking to improve chemotherapy in a shocking way. The chemical basis for Inovio is electroporation. In essence electroporation provides an electric pulse that disturbs the cell membrane, basically creating openings, through which a drug that would not otherwise be able to diffuse through is able to get inside the cell.

Inovio calls their treatment SECTA, short for Selective ElectroChemical Tumor Ablation. The idea has been best demonstrated using the chemotherapeutic bleomycin. Application of the electrical charge directly to the tumor—the technique is particularly amenable to skin cancers—greatly enhances the amount of bleomycin taken into the tumor, providing greater efficacy. This has the added advantage of reducing side-effects of the drug on healthy tissue.

The results of Phase 2 studies on head and neck cancer are impressive. Comparing efficacy of bleomycin along with bleomycin and electroporation, the number of complete and partial responses was signficant. To be clear, the number of subjects in these Phase 2 studies was small (total of 54 patients in 3 studies) and in only one of the three studies (of 25 patients) was control data with only bleomycin presented. According to the National Cancer Institute, annual treatment costs for head and neck cancer in the US is $3.2B. Inovio is currently pursuing two Phase 3 studies on head and neck cancer that are expected to be complete (according to the FDA) by August 2009 and November 2009, respectively.

Inovio (then Genetronic) published in 2005 results of a small (19 patient) clinical trial, in the journal Melanoma Research, in which the combination of electroporation with bleomycin was found to be beneficial in treating skin cancer. Pre-marketing approval for the treatment of skin cancer is being pursued in Europe . Though the thinning ozone hasn’t lately been receiving the same press as greenhouse gases, it remains a concern. According to a study published in 2005 in the British Journal of Dermatology, researchers expect the incidence of skin cancer even in The Netherlands—hardly a tropical paradise—to increase dramatically over the next decade. Inovio is also enrolling patients in a Phase 1/2 clinical study to treat breast cancer.

Inovio is using their technology to delivery DNA vaccines. Through Swedish partner Tripep they expect to begin a Phase 1 study on delivery of a DNA vaccine to treat hepatitis C early in 2007. They have also licensed this technology for DNA vaccine delivery to Wyeth Pharmaceuticals (WYE), and have licensing agreements with Merck (MRK) and Vical (VICL).

So, I really like the science behind this company, and they are pursuing good sized markets. I think the clinical results in oncology are encouraging, and the DNA vaccine delivery is an added bonus. The company’s financial situation isn’t too bad. Their most recent SEC filing (Q3 2006) had them with $6.3M net current assets and a burn rate averaging $3M per quarter. Since filing they completed a $15.25M round of financing, received $1.1M from the Department of Defense, and $4.5M from Wyeth. A more complete picture will be available when they file their 2006 10-K in a couple of weeks, but they are not in current danger of running out of money.

To be clear, this is a highly illiquid stock: market cap is barely over $100M and average (3 month) volume is 96K, so volatility is to be expected. My take is this is a good speculative stock. With big pharmaceutical companies on the hunt for biotechs, to me this seems a possible acquisition. Recall that back in October Pfizer (PFE) purchased PowderMed, a private UK company that had devel oped a way to deliver DNA by precipitating it onto gold particles, for an undisclosed sum.
