Imetelstat (GRN163L) – pro

Imetelstat or GRN163L is a drug that blocks telomerase, and is already in clinical trials as a potential treatment for breast and lung cancer.Imetelstat is a short chain oligonucleotide that binds with high affinity and specificity to the catalytic site of telomerase, resulting in competitive inhibition of enzyme activity or cell death. Imetelstat demonstrated anti-tumor effects in a wide range of preclinical models of hematological and solid tumors. There are six ongoing phase I studies patients with solid tumors, chronic lymphoproliferative disease, multiple myeloma, lung and breast cancers, as a single agent or in combination with standard treatments.
