Summary

A phase-I-first in man study in patients with calreticulin(CALR)-mutant MPN by vaccinating with exon 9 mutated peptide with the adjuvant Montanide ISA-51 to monitor safety and toxicity and the immunological response to vaccination.

Detailed description

The Philadelphia-chromosome negative chronic myeloproliferative neoplasms (MPN) are acquired cancer diseases, that arise due to mutations in the hematopoietic stem cells in the bone marrow. Median age at diagnosis is approximately 65 years of age and approximately 400 Danes are diagnosed with MPN annually. The MPN comprise essential thrombocythemia (ET), polycythemia vera (PV) and primary myelofibrosis (PMF). In December 2013 two independent research groups reported on the occurrence of somatic mutations in exon 9 of the calreticulin gene in patients with ET and PMF. The overall rationale for a vaccine with CALR-mutant epitopes is that it will initiate a CALR-mutant specific immune response, which will "release the brakes" on the CALR-mutant specific immune response. 10 patients treated with standard therapy are needed for the trial and each patient will receive 15 vaccinations over the course of one year.
