AS1411 is a novel aptamer-based anticancer technology that can be used to treat virtually any type of cancer. Aptamers are oligonucleotide or peptide molecules that bind to a specific target molecule and are typically created by selection from a large random sequence pool. The AS1411 aptamer is a G-rich oligonucleotide that targets and binds to nucleolin, a protein that is present on the surface of tumor cells.
The AS1411 aptamer has been tested as a drug in over 100 patients and is well tolerated with no evidence of severe side effects, with at least 7 patients having long-lasting clinical responses, where their cancers either disappeared or shrank substantially.
AS1411 is also a key component of Qualigen’s anti-nucleolin agent-conjugated nanoparticle drugs: AS1411-GNP, AS1411-GNP-Ra and AS1411-GNP-Im.
