In 1989 Vical discovered DNA delivery technology which they patented. Since then, Vical engages in the research and development of biopharmaceutical products based on this patented for the prevention and treatment of serious or life-threatening diseases. Potential applications of this technology include DNA vaccines for infectious diseases or cancer, in which the expressed protein is an immunogen; cancer immunotherapeutics*, in which the expressed protein is an immune system stimulant; and cardiovascular therapies, in which the expressed protein is an angiogenic growth factor.

DNA delivery technology consists in inserting DNA or RNA in the cell, without viral components or other delivery vehicles, and subsequently the expression of the proteins encoded by that genetic material. In order to achieve this typically involves the design and construction of plasmids which have genetic material encoding for: protein of interest, control of protein expression and the plasmid’s replication. Therefore, since the discovery of DNA delivery technology, Vical has improved the design of their plasmids increasing efficiency of gene expression and immunogenicity.

Research and development of other formulation and delivery technologies other than plasmids are ways to enhance DNA expression or increase the immune response in DNA vaccine applications such as: lipid molecules, synthetic polymers – poloxamers and needle-free injection.

(*) - Immunotherapy is a technique that teaches the immune system to fight cancer cells, this process is morose for that reason patients must be healthy enough and live long enough to allow the immune system to be trained. Through immunotherapy better results can be obtained.

Products


In addition to the plasmids and cationic lipids Vical has others products or potential products:
  • Allovectin-7 ® cancer immunotherapeutic - first-line treatment for metastatic melanoma.

This was Vical’s first researched and developed product in 1994. Recently phase 3 was completed and currently they are collecting data which will be available in mid 2011. This product consists of a plasmid/lipid complex containing the DNA sequences encoding HLA-B7 and B2 microglobulin, which together form a major histocompatibility complex (MHC) class I. Thus, when Allovectin-7 ® is injected directly into tumor lesions it triggers an immune response against metastatic tumors through several mechanisms.

  • TransVax™ therapeutic vaccine for cytomegalovirus (CMV), a herpes virus - Prevents
viral reactivation and disease after transplant.

The development status: phase 2 was completed and at present they are collecting and auditing all patients’ data. This product is a bivalent DNA vaccine containing plasmids encoding CMV phosphoprotein 65 (pp65) and glycoprotein B (gB) which induce cellular and humoral immune responses. TransVaxTM is formulated with a poloxamer-based delivery system.

  • CyMVectin™ prophylactic vaccine for cytomegalovirus (CMV), a herpes virus - Prevents infection before and during pregnancy to preclude fetal transmission.

Still in preclinical phase. This product consists of encoding the glycoprotein B (gB) in a plasmid.

  • Vaxfectin ® - is a cationic lipid formulation (a mixture of a cationic lipid, VC1052, and neutral co-lipid, DPyPE) optimized by Vical to increase the antibody and T-cell immune response of plasmid DNA (pDNA) vaccines. It can be use with an adjuvant for pDNA vaccine and immunotherapeutics.
  • Prophylactic vaccine for H5N1 pandemic influenza virus - Protects against infection, disease, and/or viral shedding.

Phase 1 completed. This vaccine probably will be composed of a plasmid encoding nucleoprotein (NP), an ion channel protein (M2) (two highly-conserved influenza virus proteins) and H5 hemagglutinin avian influenza virus surface protein. It’s formulated with Vaxfectin® adjunvant.
  • Prophylactic vaccine for H1N1 pandemic influenza virus - Protects against infection, disease, and/or viral shedding.

The development status: preclinical. This vaccine encodes for H1 hemagglutinin from swine type influenza virus with Vaxfectin® adjuvant.
  • Therapeutic vaccine for herpes simplex type 2 virus (HSV-2) - Prevents recurring flare-ups to reduce viral shedding and transmission.

In research. This vaccine will also be tested with Vaxfectin® adjuvant.


Vical has others products with partnership programs. The next table summarizes their corporate and government collaborations.

The different development status is according to the description in Vical’s web-page: “Research” indicates exploration and/or evaluation of a potential product candidate in a nonclinical laboratory setting. “Preclinical” indicates that a specific product candidate in a nonclinical setting has shown functional activity that is relevant to a targeted medical need, and is undergoing toxicology testing in preparation for filing an Investigational New Drug (IND) application. “Phase 1” clinical trials are typically conducted with a small number of patients or healthy subjects to evaluate safety, determine a safe dosage range, identify side effects, and, if possible, gain early evidence of effectiveness. “Phase 2” clinical trials are conducted with a larger group of patients to evaluate effectiveness of an investigational drug for a defined patient population, and to determine common short-term side effects and risks associated with the drug. “Phase 3” clinical trials involve large scale, multi-center, comparative trials that are conducted with patients afflicted with a target disease to evaluate the overall benefit-risk relationship of the investigational drug and to provide an adequate basis for product labeling ( http://www.vical.com/products/index.htm).

Financial Information


In 2009, reported financial results said that Vical had cash and investments of approximately $53 million at year-end 2009. The company raised approximately $33 million of net proceeds from the sale of equity securities during 2009, and approximately $3 million of additional net proceeds from the sale of equity securities to date in 2010. In comparison with 2008, financially, Vical generated higher revenues and reduced expenses, and they ended the year with sufficient cash to last the next two years. Operationally, Vical made extended progress and they hope for continued advancement through the achievement of key milestones in their independent and partnered product development programs throughout 2010.

On April 16th 2010, the Market Cap was $207,3 million, the Volume was $367,3 thousand and the average volume (10 D) was $274,2 thousand. (http://investing.businessweek.com/research/stocks/snapshot/snapshot.asp?ticker=VICL:US)
