Project description:The paper describes a model of multiple myeloma. Created by COPASI 4.26 (Build 213) This model is described in the article: A mathematical model of cell equilibrium and joint cell formation in multiple myeloma M.A. Koenders, R. Saso Journal of Theoretical Biology 390 (2016) 73–79 Abstract: In Multiple Myeloma Bone Disease healthy bone remodelling is affected by tumour cells by means of paracrine cytokinetic signalling in such a way that osteoclast formation is enhanced and the growth of osteoblast cells inhibited. The participating cytokines are described in the literature. Osteoclast-induced myeloma cell growth is also reported. Based on existing mathematical models for healthy bone remo- delling a three-way equilibrium model is presented for osteoclasts, osteoblasts and myeloma cell populations to describe the progress of the illness in a scenario in which there is a secular increase in the cytokinetic interactive effectiveness of paracrine processes. The equilibrium state for the system is obtained. The paracrine interactive effectiveness is explored by parameter variation and the stable region in the parameter space is identified. Then recently-discovered joint myeloma–osteoclast cells are added to the model to describe the populations inside lytic lesions. It transpires that their presence expands the available parameter space for stable equilibrium, thus permitting a detrimental, larger population of osteoclasts and myeloma cells. A possible relapse mechanism for the illness is explored by letting joint cells dissociate. The mathematics then permits the evaluation of the evolution of the cell populations as a function of time during relapse.

Project description:Autologous hematopoietic stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). However, up to 30% of MM patients are unable to collect optimal numbers of peripheral blood (PB) CD34+ hematopoietic stem and progenitor cells (HSPCs) with standard G-CSF mobilization. Motixafortide is a novel cyclic-peptide CXCR4 inhibitor with extended receptor occupancy and enhanced in-vivo activity. The GENESIS Trial is a prospective, phase III, double-blind, placebo-controlled, international, multicenter, superiority trial with 122 adult patients randomized (2:1) to motixafortide+G-CSF or placebo+G-CSF for HSPC mobilization for ASCT in MM (NCT03246529). The primary endpoint of the study was met, with motixafortide+G-CSF enabling 92.5% of patients to collect ≥6x106 CD34+ cells/kg within 2 apheresis procedures versus 26.2% with placebo+G-CSF (p<0.0001). A key, prespecified secondary endpoint was also met, with motixafortide+G-CSF enabling 88.8% of patients to collect ≥6x106 CD34+ cells/kg in 1 apheresis versus 9.5% with placebo+G-CSF (p<0.0001). Motixafortide+G-CSF was safe and well-tolerated, with the most common treatment-emergent adverse events observed being transient, Grade 1/2 injection site reactions (pain: 50%, erythema: 27.5%, pruritis: 21.3%). In addition, extended immunophenotyping and single-cell transcriptional profiling were performed on CD34+ HSPCs mobilized on the GENESIS Trial, as well as a contemporaneous MM cohort undergoing plerixafor+G-CSF mobilization for ASCT and 3 cohorts of allogeneic HSPC donors undergoing single-agent mobilization with motixafortide, plerixafor or G-CSF alone. Motixafortide+G-CSF resulted in a 10.5-fold increase in primitive HSPCs collected versus placebo+G-CSF (p<0.0001); and significantly greater numbers of early stem and progenitors versus both placebo+G-CSF (p<0.0001) and plerixafor+G-CSF (p=0.0327). Motixafortide also preferentially mobilized HSPC subsets with upregulated gene expression pathways associated with enhanced self-renewal, regeneration and quiescence (EGF, NFB/TNF and HBO1). In conclusion, motixafortide+G-CSF mobilized significantly greater CD34+ HSPC numbers within 2 apheresis procedures versus placebo+G-CSF. Motixafortide also preferentially mobilized primitive stem and early progenitor cells with unique transcriptional profiles versus plerixafor and G-CSF.
