Our Product:

HuMax-IL8 targeting cancer stem cells and tumor immunosuppression

Our first product in development is HuMax-IL8,  a medicine that inhibits the effects of interleukin 8 (IL-8), a chemokine that was recently shown to be an important target for cancer stem cells in several cancers, including breast, colorectal and liver cancer. Recent studies have also shown the importance of IL-8 signaling for tumor immunosuppression. We have a partnership with Genmab for HuMax-IL8 and have recently started a first clinical study in cancer patients.

Read more about cancer stem cells and IL-8 and HuMax-IL8.


Interleukin-8 is a factor that has been shown to be involved in the progression of many cancer forms by stimulating cancer growth, angiogensis and metastais. Recent research has also shown that IL-8 plays an important role in metastasis and epithelial mesenchymal transition (EMT) as well as cancer stem cell renewal. Moreover, IL-8 is involved in tumor immunosuppression and pre-clinical data showed that inhibition of IL-8 signaling acts synergistically with PD-1 inhibition.

Present day

Cancer treatment outcomes have improved substantially over the last decades, but many forms of cancer are still incurable if detected too late. There is a large medical need for improved therapies for those patients. Targeting cancer stem cells holds up the potential to improve on current treatment outcomes by reducing the risk of treatment failure and recurrence of the disease.

Our solution

With our first Product in development, HuMax-IL8, we are targeting cancer spread and cancer stem cells. HuMax-IL8 is a fully human antibody targeting interleukin-8. The antibody binds IL-8 with high affinity and specificity and has been through pre-clinical dvelopment as well as a phase I/II trial in patients.

Our vision

Our vision for HuMax-IL8 is that the inhibition of IL-8 will target the aggressive behaviour of cancer cells and cancer stem cells in several cancer forms. This will then increase the efficacy of existing cancer therapies as well as reduce the resistance to them. This will in turn lead to better disease control and fewer recurrencies.
