Lenzilumab shows promise in treating CMML.
תקציר
The content discusses the promising results of using lenzilumab, a GM-CSF inhibitor, in the treatment of chronic myelomonocytic leukemia (CMML). Here is a breakdown of the key points:
- CMML Treatment Challenges: CMML is a rare and aggressive malignancy with no standard care. Current treatments include azacitidine and hydroxurea.
- PREACH-M Trial: Investigating the combination of azacitidine and lenzilumab in CMML patients with RAS pathway mutations.
- Positive Results: Preliminary data from the trial showed reductions in monocyte counts, increases in platelet counts, and hemoglobin levels, along with reductions in spleen size and C-reactive protein levels.
- GM-CSF Inhibition: Lenzilumab targets GM-CSF, which has shown efficacy in patients with mutations in the RAS pathway.
- Future Implications: Researchers are optimistic about the potential of lenzilumab as a game-changer in CMML treatment.

"Objective response rates of 40%–50%"
"Complete response rate of less than 20%"
"More than 90% of cases of CMML carry somatic mutations"
"46%–60% of cases having mutations in TET2"
"40% having mutations in KRAS, NRAS, or CBL"
"5.1-fold decrease in monocyte counts (P = .03)"
"2.4-fold decrease in blast counts (P = .04)"
"Significant increase in blood hemoglobin concentration (P = .024)"
"Significant reduction in spleen size (P = .03)"

"It's [in the] early days, but if what we're seeing is durable across the next 10 patients then I think we're looking at a game changer.” - Daniel Thomas
"The biological idea that's being explored here in the clinic in this study is that by blocking, or starving if you will, those cells of that food, then you can prevent this overgrowth of certain blood cells that lead to chronic myelomonocytic leukemia.” - Cameron Durrant
