Myelofibrosis: Anyone have experience with Vonjo (pacritinib)?

Good morning
Diagnosed in June 2025 with Myelofibrosis. WBC and platelets normal. Hemoglobin between 8 and 9. I’m 65. High risk due to mutation SRSF2 along with MPL. Over 20% chance of this turning into AML. I am seeing 2 md at Mayo a BMT specialist and a Clinical trial specialist. BMT MD says best to wait on BMT until a second mutation or other s symptoms. I have no co- morbidities and am in very good health otherwise. I started a clinical trial last week for low hemoglobin. I go to Mayo weekly to see if shot given increases hemoglobin and if successful could be a monthly shot for x years. It’s unnerving to wait on BMT but I understand that the risks with BMT are high and my quality of life right now is ok. Let me know if you have questions or information needs. I will say the mutation you have really impacts the course of the disease

I posted a year ago about seeing a specialist in Myelofibrosis at Mayo Clinic. Dr. Tefferi put my on a half dose of Ojjarra to make sure I could tolerate it. My platelets were very high as was my WBCs and I was anemic. I had an enlarged spleen. The Ojjarra brought down the spleen size and stabilized my platelets and WBCs and anemia. They were still in the abnormal range but improved.
My annual visit to Mayo Clinic was uplifting for I am still not feeling any effects of the Myelofibrosis or medication. Dr. T decided to increase the medication to the full dose. It's been three weeks and my new tests reveal that everything in my CBC is totally in the normal range for the first time in four years. My biggest relief was seeing my platelets come down as my risk for clots was high.
I hope that gives you some hope for improvement.

GOOD LUCK 🍀

My husband found out in January he has myelofibrosis, it was a shock to us. He is 80 and too old for BMT. His cancer doctor put him on Vidaza it worked for awhile. Now he is on Vonjo hoping it would bring his platelet numbers up. He is on his 3rd week and doesn’t seem like it’s working. Today he had his 73rd platelet in fusion. If anyone else has experience with Vonjo please let us know.
