Reblozyl (luspatercept) has develop into the brand new normal of care for sufferers with low-risk myelodysplastic syndromes (MDS) going through anemia (low pink blood cell depend), an professional defined in an interview with CURE®.
Dr. Guillermo Garcia-Manero of the Division of Leukemia, Division of Most cancers Drugs at The College of Texas MD Anderson Most cancers Middle in Houston, led the section 3 COMMANDS research evaluating remedy with Reblozyl with remedy by way of epoetin alfa, a kind of drug referred to as an erythropoiesis-stimulating agent (ESA), which stimulates the bone marrow to provide extra pink blood cells.
“On this research, it is vitally clear that this agent [Reblozyl] is superior to a normal of care when it comes to enchancment of [blood] transfusion wants, rising ranges of hemoglobin for a major fraction of sufferers with MDS,” Garcia-Manero mentioned throughout an interview with CURE®. “So, principally, for my part, that is now the usual of look after a big majority of sufferers with anemia [and] lower-risk MDS.”
The Meals and Drug Administration (FDA) authorized Reblozyl in 2020 for the remedy of sufferers with MDS who required pink blood cell transfusions and had obtained remedy with an ESA. That approval was expanded by the FDA in 2023, primarily based on the findings of the COMMANDS trial, to incorporate the remedy of anemia in sufferers with very low- to intermediate-risk MDS who might require pink blood cell transfusions and had not obtained an ESA.

MDS encompasses many bone marrow problems that contain the bone marrow not producing sufficient wholesome blood cells, in response to the MDS Basis, which states on its web site that most individuals are anemic once they obtain an preliminary prognosis of MDS. Indicators and signs of anemia embrace fatigue, coronary heart palpitations, shortness of breath and pale pores and skin. Reblozyl, in response to the Nationwide Most cancers Institute, is meant to reinforce the bone marrow’s pink blood cell manufacturing.
COMMANDS enrolled 363 sufferers with MDS of very low danger, low danger or intermediate danger who had not been handled with ESAs and have been, attributable to anemia, depending on blood transfusions and handled with Reblozyl (182 sufferers) or epoetin alfa (181 sufferers).
The research’s major targets included no less than 12 weeks of pink blood cell transfusion independence and a imply hemoglobin improve of no less than 1.5 grams per deciliter in weeks 1 to 24 that was met by 60% of the Reblozyl group and 35% of the epoetin alfa group at median follow-ups of 17.2 months and 16.9 months, respectively.
At a median follow-up of 21.4 months within the Reblozyl group and 20.3 months within the epoetin alfa group, frequent grade 3 (extreme) or 4 (life-threatening) treatment-emergent unwanted side effects that occurred amongst sufferers handled with Reblozyl (182 sufferers) have been hypertension (19 sufferers), anemia (18 sufferers), pneumonia (10 sufferers), syncope (fainting; 10 sufferers), neutropenia (low depend of neutrophils, a kind of white blood cell; 9 sufferers), thrombocytopenia (low platelet depend; eight sufferers) and dyspnea (shortness of breath; eight sufferers) and MDS (six sufferers).
For the 179 recipients of epoetin alfa, frequent grade 3/4 treatment-emergent unwanted side effects included anemia (14 sufferers), pneumonia (14 sufferers), neutropenia (11 sufferers), MDS (10 sufferers), hypertension (eight sufferers), iron overload (seven sufferers) and COVID-19 pneumonia (six sufferers).
Researchers reported that the most typical critical treatment-emergent unwanted side effects in each teams have been pneumonia (9 within the Reblozyl group and 13 within the epoetin alfa group) and COVID-19 (eight and 10 sufferers, respectively), and one demise, attributable to acute myeloid leukemia, was thought of to be Reblozyl-related and reported on the time of the interim information evaluation.
The findings of COMMANDS, Garcia-Manero mentioned, have in flip led to the ELEMENTS-MDS trial evaluating Reblozyl amongst transfusion-independent sufferers with MDS with anemia. That section 3 research, in response to its itemizing on clinicaltrils.gov, is at present recruiting sufferers.
“Based mostly on the [established] security profile and the extent of exercise, we’re shifting into a big research taking a look at this drug [as] entrance[line treatment] in transfusion-independent sufferers with anemia,” he mentioned. “That’s really the place we predict that these medicine will actually, actually work nicely, really, when you will have important exercise.”
