Mutant CALR-peptide Based Vaccine in Patients With Mutated CALR Myeloproliferative Neoplasm
Recruiting now · Phase 1
Conditions studied: Myelofibrosis, Essential Thrombocythemia, MPN
In brief
The primary objective of this study is to assess the safety and tolerability of administrating mutated-CALR peptide Vaccine to patients with MPN. The researchers plan to enroll 10 patients over a 12 month period. Maximum length of participation in 80 weeks. Patients will be asked to complete questionnaires, bone marrow biopsies, research lab collection, and standard of care lab draw. This research will be taking place only at The Mount Sinai Hospital, specifically at the Ruttenberg Treatment Center.
