Marina Biotech this week announced that it will shortly begin enrolling the second cohort of patients in an ongoing phase Ib/IIa trial of its RNAi-based familial adenomatous polyposis treatment CEQ508.
The drug uses orally delivered attenuated Escherichia coli to transcribe shRNAs targeting beta-catenin, an oncogene that plays a role in the development of colorectal polyps that characterize the disease.
FAP is an inherited, colorectal cancer syndrome characterized by the growth of colorectal polyps. Though the polyps are initially benign, they become malignant in nearly all cases in the absence of colectomy, according to Marina.
