Matching-Adjusted Indirect Treatment Comparison to Assess the Comparative Efficacy of Ciltacabtagene Autoleucel in CARTITUDE-1 Versus Belantamab Mafodotin in DREAMM-2, Selinexor-Dexamethasone in STORM Part 2, and Melphalan Flufenamide-Dexamethasone in HOR
    Clinical lymphoma, myeloma & leukemia, 2022, Volume: 22, Issue:9

    This study estimated the comparative efficacy of ciltacabtagene autoleucel (cilta-cel; CARTITUDE-1), a chimeric antigen receptor (CAR)-T-cell therapy, versus 3 non-CAR-T therapies (belantamab mafodotin [DREAMM-2], selinexor plus dexamethasone [STORM Part 2], and melphalan flufenamide plus dexamethasone [HORIZON]), each with distinct mechanisms of action, for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) who were triple-class exposed to an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody.. Pairwise matching-adjusted indirect treatment comparisons (MAICs) were conducted using patient-level data for cilta-cel from CARTITUDE-1 and summary level data for each comparator (2.5 mg/kg cohort in DREAMM-2, modified intention-to-treat population in STORM Part 2, and triple-class refractory patients in HORIZON). Treated patients from CARTITUDE-1 who satisfied the eligibility of the comparator trial were included. MAICs adjusted for imbalances in important prognostic factors between CARTITUDE-1 and the comparator populations. Comparative efficacy of cilta-cel versus each therapy was estimated for overall response rate, complete response or better rate, progression-free survival, and overall survival.. After adjustment, patients treated with cilta-cel demonstrated at least a 3.1-fold and at least a 10.3-fold increase in the likelihood of achieving an overall response or complete response or better, respectively, at least a 74% reduction in the risk of disease progression or death, and at least a 47% reduction in the risk of death. These results were statistically significant.. Cilta-cel showed improved efficacy over each comparator for all outcomes, demonstrating its potential as an efficacious treatment for patients with triple-class exposed RRMM.

Melphalan and Exportin 1 Inhibitors Exert Synergistic Antitumor Effects in Preclinical Models of Human Multiple Myeloma.
    Cancer research, 2020, 12-01, Volume: 80, Issue:23

    High-dose chemotherapy with melphalan followed by autologous transplantation is a first-line treatment for multiple myeloma. Here, we present preclinical evidence that this treatment may be significantly improved by the addition of exportin 1 inhibitors (XPO1i). The XPO1i selinexor, eltanexor, and KOS-2464 sensitized human multiple myeloma cells to melphalan. Human 8226 and U266 multiple myeloma cell lines and melphalan-resistant cell lines (8226-LR5 and U266-LR6) were highly sensitized to melphalan by XPO1i. Multiple myeloma cells from newly diagnosed and relapsed/refractory multiple myeloma patients were also sensitized by XPO1i to melphalan. In NOD/SCIDγ mice challenged with either parental 8226 or U266 multiple myeloma and melphalan-resistant multiple myeloma tumors, XPO1i/melphalan combination treatments demonstrated stronger synergistic antitumor effects than single-agent melphalan with minimal toxicity. Synergistic cell death resulted from increased XPO1i/melphalan-induced DNA damage in a dose-dependent manner and decreased DNA repair. In addition, repair of melphalan-induced DNA damage was inhibited by selinexor, which decreased melphalan-induced monoubiquitination of FANCD2 in multiple myeloma cells. Knockdown of FANCD2 was found to replicate the effect of selinexor when used with melphalan, increasing DNA damage (γH2AX) by inhibiting DNA repair. Thus, combination therapies that include selinexor or eltanexor with melphalan may have the potential to improve treatment outcomes of multiple myeloma in melphalan-resistant and newly diagnosed patients. The combination of selinexor and melphalan is currently being investigated in the context of high-dose chemotherapy and autologous transplant (NCT02780609). SIGNIFICANCE: Inhibition of exportin 1 with selinexor synergistically sensitizes human multiple myeloma to melphalan by inhibiting Fanconi anemia pathway-mediated DNA repair.
