Quarterly Report
The following discussion and analysis should be read in conjunction with our condensed consolidated financial statements and the related notes thereto included in this Quarterly Report on Form 10-Q. The discussion and analysis may contain forward-looking statements that are based upon current expectations and entail various risks and uncertainties. Our actual results and the timing of events could differ materially from those anticipated in the forward-looking statements as a result of various factors, including those set forth under "Factors That May Affect Our Business, Future Operating Results and Financial Condition" and elsewhere in this report.
Overview
Our Business
We are a development stage biotechnology company whose primary business is to develop and license our patented and patent-pending genes, primarily eucartyotic translation initiation Factor 5A, or Factor 5A, and deoxyhypusine synthase, or DHS, and related technologies for inhibition, i.g. siRNA, in human health applications, to:
† develop novel approaches to treat inflammatory and/or apoptotic related diseases in humans; and
† develop novel approaches to treat cancer, a group of diseases in which apoptosis does not occur normally;
In agricultural applications we are developing and licensing Factor 5A, DHS and Lipase to enhance the quality and productivity of fruits, flowers, vegetables and agronomic crops through the control of cell death, referred to as senescence, and growth in plants.
Human Health Applications
We believe that our gene technology could have broad applicability in the human health field, by either inhibiting or accelerating apoptosis. Inhibiting apoptosis may be useful in preventing or treating a wide range of inflammatory and ischemic diseases attributed to premature apoptosis. Accelerating apoptosis may be useful in treating certain forms of cancer because the body's immune system is not able to force cancerous cells to undergo apoptosis via normal mechanisms.
We have commenced preclinical in-vivo and in-vitro research to determine the ability of Factor 5A to regulate key execution genes, pro-inflammatory cytokines, receptors, and transcription factors, which are implicated in numerous apoptotic diseases.
Certain preclinical human health results to date include:
† demonstrated significant tumor regression and diminished rate of tumor growth of multiple myeloma tumors in SCID mice treated with Factor 5A technology encapsulated in nanoparticles.
† increasing the median survival by approximately 250% in a tumor model of mice injected with melanoma cancer cells;
† inducing apoptosis in both human cancer cell lines derived from tumors and in lung tumors in mice;
† inducing apoptosis of cancer cells in a human multiple myeloma cell line; † measuring VEGF reduction in mouse lung tumors as a result of |
† reducing the amounts of p24 and IL-8 by approximately 50 percent in a HIV-1 infected human cell line;
† increased the survival, while maintaining functionality, of mouse pancreatic islet cells isolated for transplantation, using intraperitaneal administration of eIF-5A siRNA. Initial animal studies have shown that siRNA to Factor 5A administered prior to harvesting beta islet cells from a mouse has a significant impact not only on the survival of the beta islet cells, but also on the retention of the cells functionality when compared to the untreated beta islet cells. Additional studies have shown that the treated beta islet cells survive a pro-inflammatory cytokine challenge, while maintaining their functionality with respect to insulin production. These further studies also revealed eIF-5A's modulation of inducible nitric oxide synthase (iNOS), an important indicator of inflammation;
† demonstrating that the efficacy of our technology is comparable to that of existing approved anti-inflammatory prescription drugs in reducing certain inflammatory cytokines in mice; and
† increasing the survival rate of mice in a lethal challenge sepsis model. Additionally, a broad spectrum of systemic pro-inflammatory cytokines were down-regulated, while not effecting the anti-inflammatory cytokine IL-10.
Inhibiting Apoptosis
We believe that down-regulation of our proprietary Factor 5A gene may have
potential application as a means for controlling the effect of a broad range of
diseases that are attributable to premature apoptosis, ischemia, or
inflammation. Apoptotic diseases include glaucoma, heart disease, and certain
inflammatory diseases such as Crohn's disease, sepsis and diabetic retinopathy,
among many others. We are engaged in preclinical research on certain
inflammatory diseases. Using small inhibitory RNA's, or siRNA's, against Factor
5A to inhibit its expression, we have reduced pro-inflammatory cytokine
formation and formation of receptors for liposolysaccharide, or LPS,
interferon-gamma and TNF-alpha. We have also determined that by inhibiting
Factor 5A iNOS, MAPK, NFkB and JAK1 are downregulated, which decreases the
inflammatory cytokines formed through these pathways. Additionally, we have
shown in a mouse study that our siRNA is comparable to a steroid and to a
prescription anti-TNF drug in its ability to reduce cytokine response to LPS.
In-vivo mouse studies have shown that the siRNA against Factor 5A (i) protects
thymocyte cells from apoptosis and decreases formation of myeloperoxidase, or
MPO, TNF-a, MIP-1alpha, and IL-1 in the lungs of mice challenged with LPS; and
(ii) increases the survival rate in which sepsis was induced by a lethal
injection of LPS and reduced blood serum levels of inflammatory proteins, such
as IL-1, IL-2, IL-6, IL-12, TNF-a, IFNg and MIP-1alpha, while not effecting
IL-10, an anti-inflammatory cytokine. The siRNA's against Factor 5A are
currently being tested in several preclinical in-vivo inflammatory disease
models. Other experiments utilizing siRNA to Factor 5A include inhibition of
cell death, or
apoptosis, during the processing of mouse pancreatic beta islet cells for transplantation; the inhibition of early inflammatory changes associated with type-2 diabetes in an in-vivo rat model; and the inhibition of viral replication in a human cell line infected with HIV-1.
Proteins required for cell death include p53, interleukins, TNF-a and other cytokines, and caspases. Expression of these cell death proteins is required for the execution of apoptosis. We have found that downregulating Factor 5A by treatment with siRNA, inhibits the expression of p53, a major cell death transcription factor that in turn controls the formation of a suite of other cell death proteins. In addition, down-regulation of Factor 5A up-regulates Bcl-2, a major suppressor of apoptosis.
Accelerating Apoptosis
In pre-clinical studies, we have also established that up-regulation of Factor
5A isoform induces cell death in cancer cells through both the p53 (intrinsic)
and cell death receptor (extrinsic) apoptotic pathways. Tumors arise when cells
that have been targeted by the immune system to undergo apoptosis are unable to
do so because of an inability to activate the apoptotic pathways. Just as the
Factor 5A gene appears to facilitate expression of the entire suite of genes
required for programmed cell death in plants, the Factor 5A gene appears to
regulate expression of a suite of genes required for programmed cell death in
human cells. Because the Factor 5A gene appears to function at the initiation
point of the apoptotic pathways, both intrinsic and extrinsic, we believe that
our gene technology has potential application as a means of combating a broad
range of cancers. Through in-vitro studies, we have found that up-regulating
Factor 5A results in: (i) the up-regulation of p53; (ii) increases inflammatory
cytokine production; (iii) increases cell death receptor formation; and
(iv) increases caspase activity. These features, coupled with a simultaneous
down-regulation Bcl-2, result in apoptosis of cancer cells. In addition,
in-vitro studies have shown that up-regulation of Factor 5A also down-regulates
VEGF, a growth factor which allows tumors to develop additional vascularization
needed for growth beyond a small mass of cells.
Human Health Research Program
Our human health research program, which has consisted of pre-clinical in-vitro and in-vivo experiments designed to assess the role and method of action of the Factor 5A genes in human diseases, is performed by approximately 17 third party researchers at our direction, at the University of Waterloo, Mayo Clinic, the University of Colorado, and the University of Virginia.
Our preclinical research has yielded data that we have presented to various biopharmaceutical companies that may be prospective licensees for the development and marketing of potential applications for our technology.
Our planned future pre-clinical research and development initiatives for human health include:
† Multiple Myeloma. Advance our technology for the potential treatment of multiple myeloma with the goal of initiating a clinical trial. In connection with the potential clinical trial, we have engaged a clinical research organization, or CRO, to assist us
through the process. Together with the CRO, we will also be finalizing our evaluation of potential delivery systems for our technology in the animal model, contracting for the supply of pharmaceutical grade materials to be used in toxicology and human studies, and ultimately filing an investigational new drug application, or IND application, with the U.S. Food and Drug Administration, or FDA, for their review and consideration in order to initiate a clinical trial. We estimate that it will take less than twentyfour months to complete these objectives.
† HIV-1. We will continue in-vitro studies utilizing different siRNA delivery systems in order to increase the transfection efficiency of the siRNA to Factor 5A to determine further decreases in HIV replication and may seek animal models to test delivery systems. A nanoparticle has been identified for the delivery of Factor 5A.
† Lung Inflammation. Optimization of the delivery and dose of the siRNA against Factor 5A to the lungs may be the direction of future lung inflammation experiments. Mouse model systems may be used to illustrate the siRNA to Factor 5A's ability to reduce morbidity and mortality in lung inflammation, caused by the up-regulation of pro-inflammatory cytokines induced by flu.
† Diabetic Retinopathy. We have received encouraging results from our initial studies, which have shown a decrease in key proteins related to retinopathy, such as TNF, VEGF, and iNOS.
† Other. We may look at other disease states in order to determine the role of Factor 5A.
In order to pursue the above research initiatives, as well as other research initiatives that may arise, we have recently completed private placements of $10 million of convertible notes and common stock warrants. We have already issued and received the net proceeds from $7 million of the convertible notes and common stock warrants. The remaining $3 million from the private placements will be received upon the occurrence of the following development milestones:
† $1.5 million on the date that we enter into a supply agreement with a third party manufacturer for sufficient quantity and quality of nano-particle for encapsulation of Factor 5A gene to be used in toxicology and proof of concept human studies; and
† $1.5 million on the date that we enter into a supply agreement with a third party manufacturer to provide sufficient quantity and quality of Factor 5A DNA to carry out toxicology and proof of concept human studies under an FDA accepted IND application.
However, it may be necessary for us to raise a significant amount of additional working capital in the future to continue to pursue some of the above and new initiatives. If we are unable to raise the necessary funds or meet the corporate and scientific milestones provided for in the private placements, we may be required to significantly curtail the future development of some of our research initiative and we will be unable to pursue other possible research initiatives.
We may further expand our research and development program beyond the initiatives listed above to include other research centers.
Agricultural Applications
Our agricultural research focuses on the discovery and development of certain gene technologies, which are designed to confer positive traits on fruits, flowers, vegetables, forestry species and agronomic crops. To date, we have isolated and characterized the senescence-induced lipase gene, DHS, and Factor 5A in certain species of plants. Our goal is to modulate the expression of these genes in order to achieve such traits as extended shelf life, increased biomass, increased yield and increased resistance to environmental stress and disease, thereby demonstrating proof of concept in each category of crop.
Certain agricultural results to date include:
† longer shelf life of perishable produce; † increased biomass and seed yield; † greater tolerance to environmental stresses, such as drought and soil salinity; † greater tolerance to certain fungal and bacterial pathogens; † more efficient plant utilization of fertilizer; and † advancement to field trials in banana, lettuce, and trees. |
We have licensed this technology to various strategic partners and have entered into a joint venture. We may continue to license this technology, as the opportunities present themselves, to additional strategic partners and/or enter into additional joint ventures. Together with our commercial partners, we are currently working with lettuce, turfgrass, canola, corn, soybean, cotton, banana, alfalfa, rice and certain species of trees and bedding plants, and we have obtained proof of concept for enhanced post harvest shelf life, seed yield, biomass, and resistance to disease in several of these plant species.
We have ongoing field trials of certain trees and bananas with our respective partners. The initial field trials conducted with ArborGen over a three year period in certain species of trees have concluded and the trees have been harvested for wood quality assessment. Preliminary data from our joint field trials show significantly enhanced growth rates in some of the trees relative to controls. Through these studies and further research and development, we have selected promising genetic lines which are now being prepared fro the field.
The first and second round of banana field trials have shown that our technology extends the shelf life of banana fruit by 100%. In addition to the post harvest shelf life benefits, an additional field trial generated encouraging disease tolerance data, specific to Black Sigatoka (Black Leaf Streak Disease), for banana plants. Additional field trials for banana plants are ongoing for Black Sigatoka.
Commercialization by our partners may require a combination of traits in a crop, such as both post harvest shelf life and disease resistance, or other traits. Our near-term research and development initiatives include modulating the expression of DHS and Factor 5A genes in these plants and propagation and then propagation and phenotype testing of such plants.
Our ongoing research and development initiatives for agriculture include assisting our license and joint venture partners to:
† further develop and implement the DHS and Factor 5A gene technology in lettuce, melon, banana, canola, cotton, turfgrass, bedding plants, rice, alfalfa, corn, soybean and trees; and
† test the resultant crops for new beneficial traits such as increased yield, increased tolerance to environmental stress, disease resistance and more efficient use of fertilizer.
Commercialization Strategy
In order to address the complexities associated with marketing and distribution in the worldwide market, we have adopted a multi-faceted commercialization strategy, in which we have entered into and plan to enter into, as the opportunities present themselves, additional licensing agreements or other strategic relationships with a variety of companies or other entities on a crop-by-crop basis. We anticipate revenues from these relationships in the form of licensing fees and royalties from our partners, usage fees in the case of the agreement with Poet, or sharing gross profits in the case of the joint venture with Rahan Meristem. In addition, we anticipate payments from our partners upon our achievement of certain research and development benchmarks. This commercialization strategy allows us to generate revenue at various stages of product development, while ensuring that our technology is incorporated into a wide variety of crops. Our optimal partners combine the technological expertise to incorporate our technology into their product line along with the ability to successfully market the enhanced final product, thereby eliminating the need for us to develop and maintain a sales force.
Through April 30, 2008, we have entered into nine license agreements and one joint venture with established agricultural biotechnology companies or, in the case of Poet, an established ethanol company.
Because the agricultural market is dominated by privately held companies or subsidiaries of foreign owned companies, market size and market share data for the crops under our license and development agreements is not readily available. Additionally, because we have entered into confidentiality agreements with our license and development partners, we are unable to report the specific financial terms of the agreements as well as any market size and market share data that our partners may have disclosed to us regarding their companies.
Generally, projects with our license and joint venture partners begin by our partners transforming seed or germplasm to incorporate our technology. Those seeds or germplasm are then grown in our partners' greenhouse. After successful greenhouse trials, our partners will transfer the plants to the field for field trials. After completion of successful field trials, our partners may have to apply for and receive regulatory approval prior to initiation of any commercialization activities.
Generally, the approximate time to complete each sequential development step is as follows:
Seed Transformation approximately 1 to 2 years Greenhouse approximately 1 to 2 years Field Trials approximately 2 to 5 years
The actual amount of time spent on each development phase depends on the crop, its growth cycle and the success of the transformation achieving the desired results. As such, the amount of time for each phase of development could vary, or the time frames may change.
The development of our technology with Poet is different than our other licenses in that we are modifying certain production inputs for ethanol. That process involves modifying the inputs, testing such inputs in Poet's production process and, if successful, implementing such inputs in Poet's production process on a plant by plant basis.
The current status of each of our projects with our partners is as follows:
Project Partner Current Status Banana Rahan Meristem - Shelf Life Field trials - Disease Field trials Lettuce Harris Moran Field trial data under evaluation Melon Harris Moran Seed transformation Trees ArborGen - Growth Field trials Alfalfa Cal / West Greenhouse Corn Monsanto Just initiated Cotton Bayer Just initiated Canola Bayer Seed transformation Rice Bayer Just initiated Soybean Monsanto Just initiated Turfgrass The Scotts Company Greenhouse Bedding Plants The Scotts Company Greenhouse Ethanol Poet Modify inputs |
Commercialization by our partners may require a combination of traits in a crop, such as both shelf life and disease resistance, or other traits.
Based upon our commercialization strategy, we anticipate that there may be a significant period of time before plants enhanced using our technology reach consumers and we begin to receive royalties. Thus, we have not begun to actively market our technology directly to consumers, but rather, we have sought to establish ourselves within the industry through
presentations at industry conferences, our website and direct communication with prospective licensees.
We plan to employ the same partnering strategy in both the human health and agricultural target markets. Our preclinical research has yielded data that we have presented to various biopharmaceutical companies that may be prospective licensees for the development and marketing of potential applications of our technology. Consistent with our commercialization strategy, we intend to attract other companies interested in strategic partnerships or licensing our technology, which may result in additional license fees, revenues from contract research and other related revenues. Additionally, we have selected multiple myeloma as a target indication to develop and bring into clinical trials and may select additional human health indications to bring into clinical trials on our own. Successful future operations will depend on our ability to transform our research and development activities into commercially feasible technology.
Patent and Patent Applications
To date, we have been granted seventeen patents by the United States Patent and Trademark Office, or PTO, and nineteen patents from foreign countries, twenty-eight of which are for use of our technology in agricultural applications and eight of which relates to human health applications.
In addition to our thirty-six patents, we have a wide variety of patent applications, including divisional applications and continuations-in-part, in process with the PTO and internationally. We intend to continue our strategy of enhancing these new patent applications through the addition of data as it is collected.
