Mobilizing the Immune System in the Treatment of Oncologic and Neurodegenerative Diseases


The Antigen-presenting Cells (APCs) are responsible for maintaining the immune system’s balanced and measured response to disease by producing a broad array of signals to mobilize cellular, cytokine, and antibody defenses. Specialized APCs, the circulating monocytes, migrate to disease sites where they are transformed into pro-inflammatory or anti-inflammatory macrophages. While both types of macrophage play vital roles in defense against diseases, excessive production of either type is counter therapeutic. Elevated ratios of pro-inflammatory macrophages contribute to neuroinflammatory diseases such as Alzheimer’s, while elevated ratios of anti-inflammatory macrophages contribute to tumor growth, metastasis, and progression of cancers.


Augustus Bio Target has secured a platform targeting technology, the TargoSphere®, from Rodos Bio Target GmbH in Germany in a collaborative agreement designed to develop novel treatments for neurodegenerative diseases and cancers. The CLR-TargoSphere® is a patented carbohydrate-labeled nanocarrier that recognizes carbohydrate receptor sites on the surface of APCs and delivers encapsulated agents into a pathway that evades intracellular endolysosomal enzymatic degradation. The ability to escape degradation is critical to the successful delivery of unmodified and pharmacologically active agents to diseased sites, and is unique among all competing targeted and non-targeted nanocarriers.

Additionally, the CLR-TargoSphere® has been shown to deliver therapeutic contents across the Blood Brain Barrier, concentrated in perivascular spaces and areas rich in glial cells, with intracellular delivery into astrocytes, the cells intimately associated with Alzheimer’s disease and demyelinating disorders such as Multiple Sclerosis.

  2. CLR-TargoSphere® encapsulated curcumin
  3. CLR-TargoSphere® encapsulated gemcitabine

Paclitaxel: a generic apoptotic, antiproliferative, and immune-enhancing agent. In addition to its approved use for multiple oncologic indications, it also inhibits abnormal protein tau hyperphosphorylation in Alzheimer’s disease.

Curcumin: a generic natural curcuminoid antiproliferative and anti-inflammatory agent. It also has anti-amyloidogenic activity and induces degradation of amyloid beta deposits and uptake by macrophages in Alzheimer’s disease.

Gemcitabine: a generic antiproliferative agent approved for multiple oncologic indications, has synergistic antiproliferative activities with paclitaxel and curcumin. A non-targeted combination of gemcitabine and paclitaxel (nab-paclitaxel) was FDA approved in 2013 as a first-line treatment for metastatic pancreatic carcinoma. The CLR-TargoSphere® targeted combination of gemcitabine, paclitaxel, and curcumin is designed to improve clinical outcomes over non-targeted gemcitabine and nab-paclitaxel.


CLR-TargoSphere® encapsulated gemcitabine, paclitaxel, and curcumin have been developed for in-vivo preclinical and clinical trials to:

  1. COLON CANCER: Restoring Immune Function. We hypothesize that targeted delivery of Curcumin to antigen presenting cells in the immune system can suppress tumor growth for a variety of cancers. This study will examine tumor responses to Curcumin in a colon cancer mouse model when given alone or in combination with an immune Checkpoint Inhibitor. Positive results will lead to Fast-Track FDA applications for human and companion pet animal cancer trials. [More…]
  2. CHRONIC TRAUMATIC ENCEPHALOPATHY (CTE): CTE is caused by neurodegenerative damage associated with repeated Injuries to the head. It is found in military personnel, as well as adolescents and adults engaged in competitive sports. It is becoming a major global public health concern for which there is no treatment, and ultimately leads to progressive dementia and an untimely death.
    We have begun a preclinical study targeting the brain with CLR-TargoSphere® encapsulated Curcumin to take advantage of its multiple anti-inflammatory effects.
    Our goal is to show that CLR-TargoSphere® encapsulated Curcumin will be shuttled across the Blood Brain Barrier when targeted to Antigen Presenting Cells (APCs) of the Immune System. We are attempting to prove that APCs can deliver encapsulated curcumin to cells associated with the neurodegenerative changes found in CTE. [More…]
  3. ALZHEIMER’S DISEASE: Administer the CLR-TargoSphere® encapsulated combination of paclitaxel and curcumin to cross the Blood Brain Barrier for a dual treatment strategy to retard development of tau neurofibrillary tangles and impaired synaptic transmission, and to decrease formation and aggregation of amyloid deposits.The Goal: Delay progression of cognitive impairments in early and mid-stage Alzheimer’s disease.
  4. METASTATIC PANCREATIC ADENOCARCINOMA: Administer the CLR-TargoSphere® encapsulated combination of gemcitabine, paclitaxel, and curcumin to the primary tumor, metastases, and tumor-draining lymph nodes for a synergistic antiproliferative.The Goal: Improve progression-free and overall survival rates in comparison to the combination of non-targeted gemcitabine and nab-paclitaxel.
