Dr Klisovic on a Case Discussion of Momelotinib in Myelofibrosis With Anemia

Rebecca Klisovic, MD, chief medical information officer, University Hospitals Seidman Cancer Center, discusses 3 case studies about patients with myelofibrosis that were presented during an OncLive^® State of the Science Summit™ on hematologic oncology, which she chaired.

The first case that was discussed was on a 71-year-old male patient with newly diagnosed myelofibrosis with splenomegaly, mild anemia, a high symptom burden, and intermediate-2–risk disease, Klisovic begins. The consensus among the panelists was that this patient required treatment due to his spleen size, symptoms, and anemia, she says. Although some oncologists who participated in the discussion considered using ruxolitinib (Jakafi) because of its early survival data, the panel predominantly favored momelotinib (Ojjaara), given this agent’s potential benefit in patients with anemia, she explains.

The second case was on a 62-year-old female patient with myelofibrosis who had already received ruxolitinib and had comorbidities including symptom scoring and a large spleen, according to Klisovic. This patient also had anemia, with a hemoglobin level of 7.2 g/dL, she reports. Therefore, the focus on improving anemia made momelotinib a clear treatment choice in this setting, she adds. Whereas other case presentations prompted treatment debates between the panelists, this case was more clear cut, especially since this patient was refractory to ruxolitinib, Klisovic emphasizes.

The third case was on a 54-year-old female patient with newly diagnosed myelofibrosis that was characterized by both anemia and thrombocytopenia, as well as a platelet count of 34/µL, Klisovic says. This discussion centered around the use of pacritinib vs momelotinib, informed by the patient’s low platelet count, she explains. Some discussants raised concerns about the patient’s eligibility for momelotinib clinical trials, which have enrollment criteria with varying platelet cutoffs, she notes. Despite these concerns, most participants favored the use of pacritinib (Vonjo) due to this agent’s efficacy in managing thrombocytopenia, she reports. However, some discussants noted that momelotinib could also be a viable treatment option for patients similar to the one in this case, depending on clinical trial criteria and individual patient factors, she concludes.
