New Compounds for Treating or Preventing Obesity

Description of Technology: Available for licensing are new compounds developed for the treatment or prevention of obesity. The compounds act to block the absorption of dietary fats in the gut by interfering with signaling through the farnesoid X receptor. There is correlative evidence that inhibition of the farnesoid X receptor can reduce obesity resulting from high fat-based diets. While many farnesoid X receptor agonists are known, until now there have been no known therapeutic agents that can inhibit this receptor.

Also available for licensing are methods of synthesizing the compounds and methods of using the compounds to treat or prevent obesity.

Potential Commercial Applications:

  • Pharmaceutical treatments for obesity.
  • Pharmaceutical agents to reduce weight gain.

Competitive Advantages:

  • There are no known therapeutic agents to inhibit the farnesoid X receptor; thus, agents developed from the present technology could be first-to-market.
  • Compounds stay in the intestine and are not toxic.

Development Stage:

  • Early-stage.
  • In vitro data available.
  • In vivo data available (animal).

Chimeric Antigen Receptors to CD276 (B7-H3) for Treatment of Cancer

Description of Technology: Chimeric antigen receptors (CARs) are hybrid proteins consisting of an antibody binding fragment fused to protein signaling domains. When CARs are expressed in T-cells, the T-cells become cytotoxic towards cells expressing the proteins that the CAR recognizes. By developing a CAR that is specific for a cell surface protein that is selectively expressed on diseased cells, it is possible to selectively target those cells for destruction, thereby treating the disease.

Solid tumors are typically treated with a non-specific approach of surgical resection, followed by chemotherapy or radiation therapy. Unfortunately, such an approach is traumatic for the patient, and leads to numerous side-effects. This suggests that a more specific approach to treating solid tumors is needed. CD276 (B7-H3) is a tumor-associated antigen that is expressed on several solid tumors, making it a promising therapeutic target. This technology concerns the generation of three high-affinity CARs (CD276.1, CD276.6 and CD276.17) that target CD276. These CARs can potentially be used in the treatment of cancers associated with CD276 expression.

Potential Commercial Applications:

  • Treatment of diseases associated with increased or preferential expression of CD276.
  • Specific diseases include neuroblastoma, Ewing's sarcoma, Start Printed Page 1648rhabdomyosarcoma, and prostate, ovarian, colorectal, and lung cancers.

Competitive Advantages:

  • High affinity of the CARs increases the likelihood of successful targeting.
  • Targeted therapy decreases non-specific killing of healthy, essential cells, resulting in fewer non-specific side-effects and healthier patients.

Development Stage:

  • Early-stage.
  • In vitro data available.

Bispecific Antibodies To Target Latent HIV-1 Infection

Description of Technology: The invention describes bispecific antibodies designed to kill latently HIV-1 infected T cells. It is thought that such bispecific antibodies will reduce or eliminate the pool of HIV-1 infected cells, contributing to functional cure. The antibody constructs comprise an HIV Env-binding fragment of a broadly neutralizing antibody linked to an anti-CD3 single chain variable fragment (scFv). One embodiment is a VRC01 scFv linked to the anti-CD3 scFv . Other embodiments comprise Fab fragments of VRC07 or 10E8 antibodies linked to the anti-CD3 scFv. The bispecific antibody simultaneously stimulates infected cells to express gp120, instructs cytotoxic T cells to kill these cells, and neutralizes extraneous viral particles.

Potential Commercial Applications: Immunotherapy of HAART-suppressed HIV-1 infection.

Competitive Advantages:

  • Immunotherapy targets latently infected cells harboring virus resistant to HAART.
  • Broadly neutralizing antibody fragment neutralizes extraneous viral particles.

Development Stage:

  • Pre-clinical.
  • In vivo data available (animal).
