Prophylaxis of neutropenia with mecapegfilgrastim in patients with non-myeloid malignancies: a real-world study.

ABSTRACT:

Background

Chemotherapy-induced neutropenia is commonly encountered in clinical practice. The management of neutropenia has been evolving from short-acting granulocyte colony-stimulating factors (G-CSFs) to long-acting G-CSFs. However, an evaluation of the safety and effectiveness of long-acting G-CSFs in clinical practice is still lacking.

Methods

This multicenter, non-interventional study was aimed at exploring the safety and effectiveness of mecapegfilgrastim in different cancer patients in China. All patients provided written informed consent prior to the study and were treated according to routine clinical practice. Different prophylactic strategies (primary or secondary prophylaxis) were also compared.

Results

This study included 638 patients from May 2019 to November 2020. More than half of the participants were breast cancer patients. The mean age of all the patients was 56 years. White blood cell increase (6.2%) was the most frequently reported adverse event (AE) possibly related to the study drug. No unexpected AEs were reported. Grade ≥3 neutropenia in chemotherapy treatment cycle 1 was reported in 36 (5.6%) patients. Incidence of grade ≥3 neutropenia in cycle 1 in the primary and secondary prophylaxis subgroups were of 4.3% and 9.2%, respectively. A decreasing trend of severe neutropenia incidence was observed from cycle 1 to cycle 4.

Conclusions

Mecapegfilgrastim was generally well tolerated, and no unexpected AEs were observed in this study. Primary administration of mecapegfilgrastim led to a lower incidence of neutropenia than did secondary administration. Continuous administration of mecapegfilgrastim could keep the incidence of neutropenia to a relatively low level.

Project description:Acute myeloid leukemia (AML) represents 80% of adult leukemias and 15-20% of childhood leukemias. AML are characterized by the presence of 20% blasts or more in the bone marrow, or defining cytogenetic abnormalities. Laboratory diagnoses of myelodysplastic syndromes (MDS) depend on morphological changes based on dysplasia in peripheral blood and bone marrow, including peripheral blood smears, bone marrow aspirate smears, and bone marrow biopsies. As leukemic cells are not functional, the patient develops anemia, neutropenia, and thrombocytopenia, leading to fatigue, recurrent infections, and hemorrhage. The genetic background and associated mutations in AML blasts determine the clinical course of the disease. Over the last decade, non-coding RNAs transcripts that do not codify for proteins but play a role in regulation of functions have been shown to have multiple applications in the diagnosis, prognosis and therapeutic approach of various types of cancers, including myeloid malignancies. After a comprehensive review of current literature, we found reports of multiple long non-coding RNAs (lncRNAs) that can differentiate between AML types and how their exogenous modulation can dramatically change the behavior of AML cells. These lncRNAs include: H19, LINC00877, RP11-84C10, CRINDE, RP11848P1.3, ZNF667-AS1, AC111000.4-202, SFMBT2, LINC02082-201, MEG3, AC009495.2, PVT1, HOTTIP, SNHG5, and CCAT1. In addition, by performing an analysis on available AML data in The Cancer Genome Atlas (TCGA), we found 10 lncRNAs with significantly differential expression between patients in favorable, intermediate/normal, or poor cytogenetic risk categories. These are: DANCR, PRDM16-DT, SNHG6, OIP5-AS1, SNHG16, JPX, FTX, KCNQ1OT1, TP73-AS1, and GAS5. The identification of a molecular signature based on lncRNAs has the potential for have deep clinical significance, as it could potentially help better define the evolution from low-grade MDS to high-grade MDS to AML, changing the course of therapy. This would allow clinicians to provide a more personalized, patient-tailored therapeutic approach, moving from transfusion-based therapy, as is the case for low-grade MDS, to the introduction of azacytidine-based chemotherapy or allogeneic stem cell transplantation, which is the current treatment for high-grade MDS.
