Company Overview

Qualigen Therapeutics is a clinical-stage therapeutics company focused on developing treatments for adult and pediatric cancers with potential for Orphan Drug Designation. Our investigational QN-302 compound is a small molecule selective transcription inhibitor with strong binding affinity to G4s prevalent in cancer cells; such binding could, by stabilizing the G4s against “unwinding,” help inhibit cancer cell proliferation. The investigational compounds within Qualigen’s family of Pan-RAS oncogene protein-protein interaction inhibitor small molecules are believed to inhibit or block the binding of mutated RAS genes’ proteins to their effector proteins, thereby leaving the proteins from the mutated RAS unable to cause further harm. In theory, such mechanism of action may be effective in the treatment of about one quarter of all cancers, including certain forms of pancreatic, colorectal, and lung cancers.

In July 2023, Qualigen sold its FastPack® diagnostics business to Chembio Diagnostics, Inc., an American subsidiary of French diagnostics provider BIOSYNEX Group, a leader in the design and distribution of rapid tests.
