WF10 is a solution of OXO-K993 containing stabilized chlorite ions.  The solution focuses on supporting the immune system by targeting the macrophage, a type of white blood cell that coordinates much of the immune system to regulate normal immune function.

WF10 appears to act on the macrophage. Normally functioning macrophages can alternate between one of two basic states: phagocytic and inflammatory. Phagocytic macrophages digest invading organisms, such as viruses, and initiate a biological defence pathway. Inflammatory macrophages, in turn, induce a variety of reactions, including fever, sweating, swollen glands, malaise and appetite loss, the common, uncomfortable signs of illness. Such responses, while entirely normal, must be turned on and off in a controlled manner. If left unchecked pathogens can overdrive the system toward the inflammatory state creating an imbalance that may lead to such medical disorders as chronic inflammation, immune deficiency, organ damage and tumour proliferation.

WF10’s proposed mode of activity is based on a theory about how macrophages regulate the immune system. Research suggests that, in some cases, WF10 may rebalance improperly functioning immune systems. The drug has potential applications in adjuvant cancer therapy, diseases related to immune deficiencies and the management of chronic viral infections.
