Research on immunotherapy with histamine dihydrochloride.
Relapse after the completion of induction and consolidation chemotherapy in acute myeloid leukemia (AML) is a significant reason why only approximately 30% of adult AML patients survive beyond five years after diagnosis. Apart from allogeneic stem cell transplantation there is no consensus about relapse-protective therapy in the post-consolidation phase and the standard of care for most patients hence is no treatment.
Immunotherapy with histamine dihydrochloride
Our group has developed immunotherapy with histamine dihydrochloride (HDC) to counteract leukemia-related immunosuppression in AML and hence to ameliorate the efficiency of other immunotherapies, including interleukin-2 (IL-2).
The immunostimulatory features of HDC are assumed result from inhibition of the formation of reactive oxygen species (ROS) by several types of myeloid cells. By diminishing the availability of extracellular ROS, HDC provides a reduced environment suitable for optimal survival and function of anti-leukemic lymphocytes. HDC and IL-2 synergistically activate T- and NK-cell functions in the presence of normal and malignant myeloid cells; in this immunosuppressive microenvironment, the efficiency of IL-2 alone is strongly reduced.
These findings formed the background to the introduction of HDC/IL-2 as a strategy to prevent relapse of AML. A randomized phase III trial with 320 patients in the post-chemotherapy phase demonstrated a sustained and significant reduction of relapse risk after immunotherapy with HDC + low-dose IL-2, which was approved for use within the EU in 2009 and became available for AML patients in Europe in 2010. HDC/IL-2 is the first approved therapeutic to reduce the incidence of relapse in the post-chemotherapy phase of AML.
Two new indications
We will evaluate the potential benefit of HDC/IL-2 in two new indications. In cooperation with the Karolinska Hospital, we will assess clinical and immunomodulatory effects of treatment with HDC/IL-2 + nivolumab in patients with metastatic cancer who have failed to respond to checkpoint inhibitor therapy (NIVOCEP trial). In the PANCEP trial, patients with resectable pancreatic cancer will receive pre- and postoperative HDC/IL-2 aiming to reduce the risk of distant metastasis.
Research tools and resources
The clinical trials are performed at the Sahlgrenska University Hospital (PANCEP trial) and the Karolinska Hospital (NIVOCEP trial). Contemporary aspects of cellular immunity are analysed at the TIMM Laboratory at Sahlgrenska Cancer Center.
