About this study

Official title: A Phase-1-first in Man Study in Patients With CALR-mutant Myeloproliferative Neoplasms by Vaccinating With CALR Exon 9 Mutant Peptide

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CALRLong36 peptide in people with Myeloproliferative Neoplasm, Unclassifiable and Essential Thrombocythemia, run by Inge Marie Svane at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events evaluated by CTCAE 4.03 (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03566446, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2023.
