We target drugs to cancer cells by attaching them to ligands that bind with high specificity for a receptor on cancer cells. By concentrating the anti-cancer drug in the malignant cells, we improve both drug potency and toxicity. Eight ligand-targeted drugs from our lab are currently in human clinical trials and the same tumor-specific targeting ligands are being used to target CAR T cells specifically to tumor tissues. Along similar lines, we are targeting immune modulators to specific immune cell types for the purpose of reprogramming these cells from a tumor-supporting to tumor-killing phenotype.
We develop bone anabolic drugs that concentrate selectively on a bone fracture surface and dramatically improve both the rate and quality of fracture healing. Applications for this technology include improving the repair of virtually all bone fractures, spinal fusions, facial reconstruction surgeries, bone lengthenings and bone grafts, etc. Related technologies to facilitate repair of traumatized soft tissues and nerves are also being developed.
Treatment of Infectious Diseases
We are designing new therapies for malaria and multiple viral diseases, including HIV, HBV, influenza virus, and SARS-cov-2 (i.e. the causative agent in COVID_19). As with our other therapies, our anti-viral drugs are specifically targeted to both free virus and virus-infected host cells, thereby avoiding any collateral toxicity to healthy cells.
Reprogramming of the Immune System
Because an imbalance in the immune system contributes to the pathologies of almost all major diseases, including cancers, autoimmune, CNS, cardiovascular, metabolic and fibrotic diseases, we are developing targeting ligands that can deliver attached drugs very selectively to specific immune cell types. Immune cells for which we currently have specific targeting ligands include activated macrophages, regulatory T cells, antigen presenting cells, activated fibroblasts, and exhausted CAR T cells. Drugs that are being targeted to these cell types include agents that activate, inhibit, proliferate, differentiate or kill these specific immune cells.
Treatment of Erythrocyte Diseases
We have developed a new therapy for malaria in collaboration with Drs. Franco Turrini, Antonella Pantaleo and Huynh Dinh Chien, that is in phase 2B human clinical trials in SE Asia. We have also designed a new therapy for sickle cell disease that is undergoing clinical trials in the USA. Efforts to optimize and improve these therapies are under investigation.
