HGF, sIL-6R and TGF-?1 Play a Significant Role in the Progression of Multiple Myeloma.

ABSTRACT: Background. In the last few years, it has been widely reported that proinflammatory and angiogenic cytokines are important for the development and progression of multiple myeloma (MM). Objectives. To further validate and acquire more insight into this view we decided to check whether plasma levels of certain cytokines and their soluble receptors differ between MM patients and healthy subjects. Patients and Methods. The study was conducted in 76 MM patients aged 22 to 77 years (60±10 years) and 35 healthy controls aged 20 to 63 years (33±10 years). Plasma levels of interleukin-6 (IL-6), b-fibroblast growth factor (b-FGF), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and transforming growth factor-?1 (TGF-?1), as well as soluble receptors for IL-6 (sIL-6R) and VEGF (sVEGF-R2) were measured using enzyme-linked immunosorbent assay (ELISA). Results. Significantly higher plasma levels of IL-6 (13.65±42.61 vs. 1.04±1.12 pg/ml, p=0.006), HGF (2174±2714 vs. 648±130 pg/ml, p<0.001), b-FGF (7.92±10.78 vs. 2.54±5.38 pg/ml, p<0.001) and sIL-6R (37.1±14.2 vs. 25.3±6.4 ng/ml, p=0.003) were observed in MM patients vs. healthy controls, respectively. Plasma sVEGF-R2 was significantly lower in MM patients than in controls (7518±2119 vs. 8725±1281 pg/ml, respectively; p<0.001). We observed an inverse correlation between length of treatment and the level of sIL-6R, and TGF-?1 in plasma. Conclusions. Plasma levels of HGF, b-FGF, IL-6 and sIL-6R in MM patients were higher ??when compared to the control group. Antineoplastic therapy leads to a time-dependent decrease in plasma levels of sIL-6R, and TGF-?1 in MM patients. Blood plasma level of HGF is an optimal measure to differentiate patients in whom disease is progressing versus patients who respond to therapy.

Project description:Functional blockade of the transforming growth factor-beta (TGF-β) signaling pathway improves the efficacy of cytotoxic and immunotherapies. We conducted a phase 1b study to determine the safety, efficacy, and maximal tolerated dose (200 mg po bid) of the potent, orally-available TGF-β type I receptor kinase inhibitor vactosertib in relapsed and/or refractory multiple myeloma patients who had received ≥2 lines of chemoimmunotherapy. Vactosertib combined with pomalidomide was well-tolerated at all doses, had a manageable adverse event profile and induced durable responses with 80% progression-free survival (PFS-6) at 6 months, while pomalidomide alone historically achieved 20% PFS-6. Following treatment, the immunosuppressive marker PD-1 expression was reduced on patient CD8+ T-cells. Following ex vivo treatment, vactosertib decreased PD-1 expression on patient CD138+ cells, reduced PD-L1/PD-L2 on patient CD138+ cells and enhanced the anti-myeloma activity of autologous T-cells. Taken together, vactosertib is a safe immunotherapy that modulates the T-cell immunophenotype to reinvigorate T-cell fitness. Multiple myeloma (MM) is a genetically heterogeneous hematologic malignancy characterized by the excessive proliferation of clonal plasma cells (1, 2). MM remains mostly incurable but a small group of patients can achieve long-term remission (3). Treatment of MM presents unique challenges due to the complex molecular pathophysiology and genetic heterogeneity (4, 5). Given that MM is the second most common blood cancer characterized by cycles of remission and relapse, the development of new therapeutic modalities is crucial (6, 7). The prognosis for MM patients has improved substantially over the past two decades with the development of more effective therapeutics, e.g., proteasome inhibitors, and regimens that demonstrate greater anti-tumor activity (8-10). The management of RRMM represents a vital aspect of the overall care for patients with disease and a critical area of ongoing scientific and clinical research (10-12).
