The Use of Chimeric Antigen Receptor To Control HIV Infection

    Description of Technology: Chimeric Antigen Receptors (CARs) are 
engineered proteins expressed by transduction on autologous CD8 T 
cells; after adoptive transfer, they promote targeted killing of 
specific cell types. CARs are showing great promise for treating 
cancer. The present invention (CD4-CRD CAR) is a novel bifunctional 
targeting motif for an anti-HIV CAR, consisting of a region of human 
CD4 linked to a carbohydrate recognition domain (CRD) from one of 
several human C-type lectins known to interact with high-mannose 
glycans on HIV gp120. Compared to a ``standard'' CD4 CAR, the CD4-CRD 
CAR displays two major enhancements: (1) Increased potency for 
suppression of HIV-1 infection by selective killing of productively 
infected cells, and (2) complete absence of CD4-mediated entry receptor 
activity that would otherwise render the transduced CD8 T cells 
susceptible to HIV infection. Compared to antibody-based anti-HIV CARs, 
the CD4-CRD CAR of the present invention is predicted to have two major 
advantages: (1) Lower escape potential, due to the universality of HIV 
CD4-dependence and high-mannose glycan display on gp120, and (2) 
reduced immunogenicity, since the all-human CD4-CRD CAR sequences are 
devoid of variable regions that would likely elicit anti-idiotypic 
antibody responses against scFv-based targeting motifs.
    Potential Commercial Applications:
    <bullet> Therapy for HIV infection
    <bullet> Research on antiretroviral infection
    Competitive Advantages: Enhanced potency for HIV inhibition and 
does not render transduced CD8T cells susceptible to HIV infection.
    Development Stage:
    <bullet> In vitro data available
    <bullet> In vivo data available (animal)

Photo-Controlled Removal of Targets In Vitro and In Vivo

    Description of Technology: The invention relates to a novel 
technology for separation, isolation and removal of target molecules or 
cells from a complex mixture. The technology can be used for both in 
vitro and in vivo applications. It comprises a conjugate of a 
biomolecule with specific binding activity (e.g. antibody, hapten, 
protein, nucleic acid) and the fluorescence dye IR700. When the 
conjugate is allowed to contact with a sample, it binds to the target 
molecule in the sample to form a biological complex. Upon exposure to 
near infrared light (NIR) of approximately 700 nm the biological 
complex becomes hydrophobic due to cleavage of a part of the 
fluorescent dye. Such hydrophobic complex can aggregate and readily be 
separated and removed from the biological mixture. The technology can 
be used in a broad range of applications, such as environmental or food 
(removal of contaminants from samples), or in vivo removal of toxins, 
pathogens or drugs from a subject, where the latter may provide a 
photo-controlled way to control the pharmacokinetics of a drug in vivo. 
The technology can also be applied in the therapeutic field, for 
example in cancer therapy, by killing and removal of tumor cells in a 
subject with the aid of wearable NIR device. In such treatment, the 
aggregated target cells may be removed from the subject via the liver 
and/or spleen.
    Potential Commercial Applications:
    <bullet> Environmental or food (removal of contaminants from 
samples)
    <bullet> In vivo removal of toxins, pathogens or drugs from a 
subject
    <bullet> Cancer therapy
    Competitive Advantages: Simple and versatile way to separate and 
remove molecules or cells from a complex mixture.

Human Monoclonal Antibodies Against 5T4 as Therapeutic Agents

    Description of Technology: 5T4 is an antigen expressed in a number 
of carcinomas. Its expression is limited in normal tissue, but is 
prevalent in malignant tumors throughout their development. This 
confined expression makes it an attractive target for cancer 
immunotherapy. 5T4 is often found in colorectal, ovarian, and gastric 
tumors and thus has been used as a prognostic aid for these cancers. In 
addition, its role in antibody-directed immunotherapy for delivering 
response modifiers to tumors has been studied using murine monoclonal 
antibodies (mAbs) and the cancer vaccine TroVax (currently in clinical 
trials for multiple solid tumors) targets 5T4.
    The present invention describes the identification and 
characterization of two fully human mAbs (m1001 and m1002) that bind to 
5T4. Since the mAbs are fully human, they could have less 
immunogenicity and better safety profiles than the existing mouse and 
humanized antibodies. These mAbs have the potential to be cancer 
therapeutics as naked mAbs, Chimerica Antigen Receptors (CARs) and/or 
Antibody-Drug Conjugates (ADCs).
    Potential Commercial Applications: A mAb, CAR, or ADC therapeutic 
for the

treatment of various human cancers expressing 5T4.
    Competitive Advantages:
    <bullet> The fully human antibodies may have better drugability, 
especially less immunogenicity and better safety.
    <bullet> This antibodies could be used as naked mAbs, CARs and/or 
as ADCs.
    <bullet> The confined expression of 5T4 makes it an attractive 
target for cancer immunotherapy.
    <bullet> 5T4 mAbs could be used to treat several solid tumor 
cancers.
    Development Stage: In vitro data available

Quantitative Multiplex Methods for Rapid Detection and Identification 
of Viral Nucleic Acids

    Description of Technology: The subject technologies are 
quantitative multiplex loop mediated isothermal amplification assays 
that can detect and distinguish different viral pathogens, including 
HIV, Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), Hepatitis E 
Virus (HEV), Dengue Virus (DENV), Chikungunya virus (CHIKV) and West 
Nile Virus (WNV). The assay has the advantage of distinguishing between 
different genotypes of HCV. It has the potential to detect other 
pathogens. A quantitative multiplex variation of the assay can detect 
and identify all seven viruses using one reaction mixture. The 
detection-reaction is performed on a simple heat-source and viral 
quantitation can be measured using a simple fluorospectrophotometer. 
The entire detection process using these assays can be accomplished 
within 30 to 60 minutes in a doctor's office, laboratory setting, or in 
the field. Detection limits of as little as 1-10 International Units 
(viral copies) are possible with the use of fluorogenic 
oligonucleotides. The assays demonstrate very high specificity when 
tested with human clinical samples.
    Potential Commercial Applications: Detection assays for viral 
pathogens such as HIV, HBV, HCV, HEV, Dengue Virus, Chikungunya, and 
West Nile Virus.
    Competitive Advantages:
    <bullet> Assays can be completed within 30 to 60 minutes and in a 
doctor's office, laboratory setting, or in the field.
    <bullet> Assays can be performed without expensive instrumentation 
or specialized technical operators.
    <bullet> Assays are highly specific and can distinguish between 
different viruses and between different genotypes of viruses.
    Development Stage:
    <bullet> Early-stage
    <bullet> In vitro data available
    <bullet> In vivo data available (human)
