Epeius Biotechnologies

Scientists at Epeius Biotechnologies have developed a targeted delivery system (TDS) that can transport genes or other therapeutic agents directly to diseased areas in the body. This pathotropic, or disease-seeking, technology has enabled the company to develop Rexin-G, a tumor-targeted, injectable gene delivery system that has demonstrated remarkable safety and single-agent efficacy in clinical trials internationally. Rexin-G is currently in clinical trials for pancreatic cancer in the U.S. ƒƒ‚ƒš‚" where it has achieved FDA orphan drug status ƒƒ‚ƒš‚" and has accelerated approval in the Philippines for the treatment of all solid tumors that are resistant to standard chemotherapy. The company's international clinical outreach with Rexin-G has enabled us to expedite further demonstrations that Rexin-G is highly active in a broad spectrum of chemo-resistant tumor types with efficacy and excellent safety profiles. The company are a biopharmaceutical company focused on expanding the therapeutic utility and commercialization of the company's pathotropic approach to disease treatment through internal development and commercialization of the company's oncology products and cancer vaccines, and through strategic partnerships in additional areas of oncology, immunology, cardiovascular, ocular, and wound healing applications, precision targeted diagnostics, and stem cell technologies.

Vector Biolabs

Vector Biolabs is a biotechnology company focused on developing robust gene delivery products, by using its technologies. The company's products are to be used in scientific research, target identification and drug development.

DNAtriX Logo

DNAtrix is developing modified viruses for the treatment of the most aggressive forms of cancer. Since viruses are already efficient at killing cells, scientists have harnessed this ability by modifying a common cold virus so that it targets and selectively kills cancer cells.


ParentPlus LLC was formed to alleviate male-factor subfertility by bringing biotechnology to millions of subfertile couples for whom intra-uterine insemination (IUI) might be an appropriate therapy. This therapy, with spousal or donor sperm, is underutilized perhaps in part because it frequently is neglected in the popular press. It is the company's belief that sperm from many subfertile men should be the target of a therapy based on modern biotechnology. Successful application of this concept could allow far more subfertile couples, when male-factor subfertility is a problem, to use IUI with spousal sperm to fulfill their dream of a having a baby. Hence, the focus of ParentPlus LLC is on reproductive media to enhance success primarily via IUI, but also enhancing IVF. In due course, demonstrated increased success rate with IUI using ParentPlus products will increase acceptance of IUI as the low cost alternative to highly publicized expensive treatments.

Aliva Biopharmaceuticals

Aliva Biopharmaceuticals is a company that received a SBIR Phase I grant for a project entitled: Humanized Mouse Ig system employing BAC. Their research project aims to introduce the entire human immunoglobulin locus into the mouse in order to enable the subsequent production of completely humanized monoclonal antibodies from hybridomas. Monoclonal antibodies against cell surface proteins are currently being used for a variety of clinical indications, including cancer and autoimmunity. Their binding avidity and specificity make them one of the most important modes of therapy for the treatment of a variety of diseases where specific targeting is required. The current technology is based on a system where only 80% of the immunoglobulin locus has been humanized. Replacement of the remaining mouse genes with the human ones will improve the quality and diversity of the antibodies produced and as such, will be an important contribution to this important therapeutic modality.

Dicerna Pharmaceuticals Logo
Dicerna Pharmaceuticals

Dicerna Pharmaceuticals is a pharmaceutical company developing RNA interference (RNAi)-based therapeutics against genetically-defined targets in multiple disease areas, including cancer. Dicerna's therapeutic approach utilizes its Dicer Substrate siRNA (DsiRNA) molecules and EnCore drug delivery technologies to silence previously undruggable disease targets, offering a potential new treatment option for patients. Dicerna delivers its DsiRNA molecules to cancer cells using its EnCore lipid nanoparticle drug delivery technology. EnCore has been specifically engineered to accumulate in tumors and mediate efficient delivery of the DsiRNAs to the RNAi machinery in the cancer cell cytoplasm. Encore particles are well tolerated and manufactured using well-established unit operations to ensure commercial scalability.
