RGX-202

RGX-202 is a small molecule that suppresses gastrointestinal cancer growth by inhibiting a novel cancer metabolism pathway involved in supplying energy to cancer cells.

Mechanism of Action

RGX-202 Tumor environment

Creatine metabolism has been implicated in colon cancer progression and metastatic colonization of the liver. Cancer cells upregulate and release creatine kinase-B (CKB) into the extracellular space, where it generates the high energy metabolite phosphocreatine.

Phosphocreatine is imported via the creatine transporter SLC6a8, the target of RGX-202 that is over-expressed in several prevalent cancer types, including gastrointestinal cancers.

Intracellular phosphocreatine can be converted to ATP to fuel the survival of cancer cells as they proliferate and spread. Consistent with this finding, genetic depletion of SLC6a8 in colon and pancreatic cancer cell lines significantly reduced cancer growth in animal studies.1

Activity

RGX-202 is an investigational drug candidate. Pre-clinical research demonstrates that RGX-202 is active both as a single agent as well as in combination with standard-of-care therapies in several gastrointestinal cancer models.2 Oral administration of RGX-202 induces apoptosis (cell death) of colon cancer cells in mice. RGX-202 suppresses the growth of colorectal, pancreatic, and gastric cancers when used as a single agent in animal models, where it has also demonstrated enhanced activity in combination with chemotherapy.

Pipeline

RGX-104

RGX-104 is a novel oral small molecule immunotherapy in development for the treatment of solid tumors, including drug-resistant malignancies.

Pipeline

RGX-019

RGX-019 is a monoclonal antibody that targets key pathway that drives tumor progression and metastasis of several cancer types, including triple-negative breast cancer.
