Increased cyclin-dependent kinase 5 (CDK5) activity has recently emerged as a contributor to cancer progression. Researchers at the National Cancer Institute (NCI) and at the National Institute of Neurological Disorders and Stroke (NINDS) have shown that TP5, a small peptide inhibitor of CDK5 modified to facilitate passage through the blood brain barrier (BBB), has potential therapeutic benefit in glioblastoma (GBM) and colorectal carcinoma (CRC). NCI is seeking parties interested in co-developing and/or licensing TP5 for its use in the treatment of cancers with aberrant CDK5 expression as a mono-therapy or in an adjuvant setting with current standard-of-care.
The present invention describes novel virus-like particles (VLPs) that are capable of binding to and replicating within a target mammalian cell, including human cells. The claimed VLPs are safer than viral delivery because they are incapable of re-infecting target cells. The National Cancer Institute's Protein Expression Laboratory seeks parties interested in licensing the novel delivery of RNA to mammalian cells using virus-like particles.
