Pacritinib, sold under the brand name Vonjo, is an anti-cancer medication used to treat myelofibrosis.[1][2] It is a macrocyclic protein kinase inhibitor. It mainly inhibits Janus kinase 2 (JAK2) and Fms-like tyrosine kinase 3\CD135 (FLT3).
Common side effects include diarrhea, low platelet counts, nausea, anemia, and swelling in legs.[2]
Medical uses
[edit]Pacritinib in indicated to treat adults who have a rare form of a bone marrow disorder known as intermediate or high-risk primary or secondary myelofibrosis and who have platelet (blood clotting cells) levels below 50,000/μL.[1][2]
History
[edit]The effectiveness and safety of pacritinib were demonstrated in a study that included 63 participants with intermediate or high-risk primary or secondary myelofibrosis and low platelets who received pacritinib 200 mg twice daily or standard treatment.[2] Effectiveness was determined based upon the proportion of participants who had a 35% or greater spleen volume reduction from baseline to week 24.[2] Nine participants (29%) in the pacritinib treatment group had a 35% or greater spleen volume reduction, compared to one participant (3%) in the standard treatment group.[2]
The U.S. Food and Drug Administration (FDA) granted the application for pacritinib priority review, fast track, and orphan drug designations.[2]
