•IXA added to POM and DEX improved PFS in patients with LEN-refractory multiple myeloma at first relapse.•The safety profile of the IXA-POM-DEX triplet therapy was favorable and support phase 3 study of this all-oral regimen.

Part B of this phase 1b study (ClinicalTrials.gov number, NCT02283775) evaluated safety and efficacy of a fixed-volume infusion of isatuximab, an anti-CD38 monoclonal antibody, in combination with pomalidomide and dexamethasone (Pd) in relapsed/refractory multiple myeloma patients. Isatuximab (10 mg/kg weekly for 4 weeks, then every other week) was administered as a fixed-volume infusion of 250 mL (mL/h infusion rate) with standard doses of Pd on 28-day cycles. Patients (N= 47) had a median of three prior treatment lines (range, 1–8). Median duration of exposure was 36.9 weeks and median duration of first, second, and 3+ infusions were 3.7, 1.8, and 1.2 h, respectively. The most common non-hematologic treatment-emergent adverse events were fatigue (63.8%), infusion reactions (IRs), cough, and upper respiratory tract infection (40.4% each). IRs were all grade 2 and occurred only during the first infusion. The overall response rate was 53.2% in all patients (55.5% in response-evaluable population, 60.0% in daratumumab-naïve patients). Efficacy and safety findings were consistent with data from the isatuximab plus Pd infusion schedule in Part A of this study and also from the phase 3 ICARIA-MM study, and these new data confirm the safety, efficacy, and feasibility of fixed-volume infusion of isatuximab.

The spectrum of immunoglobulin paraprotein-associated diseases requiring therapy extends beyond multiple myeloma and AL amyloidosis. Awareness of these is essential in ensuring timely accurate diagnosis and appropriate treatment. As most paraprotein-associated diseases are fairly uncommon, therapeutic decisions must often be made in the absence of data from randomized controlled trials. Treatment is generally directed at the underlying clonal cell population. This review focuses on the spectrum of the less common paraprotein-associated disorders. In most instances, the monoclonal immunoglobulin plays a direct role in the pathophysiology of the disease course; in a select few, the paraprotein may be a disease marker.

Selinexor is an oral, small molecule inhibitor of the nuclear export protein exportin 1 with demonstrated activity in hematologic and solid malignancies. Side effects associated with selinexor include nausea, vomiting, fatigue, diarrhea, decreased appetite, weight loss, thrombocytopenia, neutropenia, and hyponatremia. We reviewed 437 patients with multiple myeloma treated with selinexor and assessed the kinetics of adverse events and impact of supportive care measures. Selinexor reduced both platelets and neutrophils over the first cycle of treatment and reached a nadir between 28 and 42 days. Platelet transfusions and thrombopoietin receptor agonists were effective at treating thrombocytopenia, and granulocyte colony stimulating factors were effective at resolving neutropenia. The onset of gastrointestinal side effects (nausea, vomiting, and diarrhea) was most common during the first 1–2 weeks of treatment. Nausea could be mitigated with 5-HT3 antagonists and either neurokinin 1 receptor antagonists, olanzapine, or cannbainoids. Loperamide and bismuth subsalicylate ameliorated diarrhea. The primary constitutional side effects of fatigue and decreased appetite could be managed with methylphenidate, megestrol, cannabinoids or olanzapine, respectively. Hyponatremia was highly responsive to sodium replacement. Selinexor has well-established adverse effects that mainly occur within the first 8 weeks of treatment, are reversible, and respond to supportive care.

Background

Introduction

Multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) are plasma cell disorders of aging. The landscape of the diagnosis and management of MM and MGUS are rapidly changing. This article provides an updated understanding of the clinical presentation, evaluation, diagnosis, and management of older adults with MM and MGUS. Because most oncology providers are not formally trained in geriatric medicine, geriatricians play a key role in providing oncologists with a broader understanding of patient health status in the hope of improving outcomes for older adults with MM.

Introduction:Light chain deposition disease (LCDD) is a rare complication of monoclonal gammopathies, defined by non-amyloid linear monoclonal light chain (most commonly kappa) deposits in the kidney and other organs. The rarity of LCDD has hampered clinical studies and staging systems and response criteria are lacking. The International Kidney Myeloma Working Group (IKMG) started a clinical data collection from all participating centers in order to define the natural history of LCDD, and to establish prognostic factors and response criteria in a large, international, unselected patient population.

Background:Selinexor (SEL) is a novel, first-in-class oral selective inhibitor of nuclear export (SINE) which blocks XPO1, forcing the nuclear retention and activation of tumor suppressor proteins, ultimately causing apoptosis in cancer cells. The SVd regimen with once weekly (QW) oral SEL (100 mg), dexamethasone (dex) and QW bortezomib (BOR) had significantly increased progression free survival (PFS) and overall response rate (ORR) with significantly reduced peripheral neuropathy as compared to standard twice weekly BOR/dex (Vd) in the phase III BOSTON study. Pomalidomide (POM) plus dex (Pd) achieved an ORR of 31% and PFS of 4 months in patients (pts) with disease refractory to BOR and lenalidomide (LEN). We hypothesize that the all oral Pd combination with the addition of QW SEL (SPd) would demonstrate improved activity and acceptable tolerability as compared with Pd.

Background:Selinexor (SEL) is a novel, first-in-class oral selective inhibitor of nuclear export (SINE) which blocks XPO1, forcing the nuclear retention and activation of tumor suppressor proteins, ultimately causing cell death in cancer cells. SEL 80 mg and dexamethasone (dex) 20 mg, both twice weekly (BIW), received accelerated approval from the FDA for patients (pts) with relapsed refractory multiple myeloma (RRMM). SEL continues to be evaluated in earlier lines of therapy with once weekly administration and in combination regimens. The SVd regimen with onceweekly (QW) oral SEL (100 mg), dexamethasone (dex) and QW bortezomib (BOR) had significantly increased progression free survival (PFS) and overall response rate (ORR) with significantly reduced peripheral neuropathy as compared to standard BIW BOR/dex (Vd) in the phase III BOSTON study. The combination of lenalidomide (LEN) and dex (Rd) is an approved regimen in RRMM and newly diagnosed MM (NDMM) with an ORR of 70-76% in RRMM but a low complete response rate. SEL showed synergistic antitumor activity with LEN in a MM xenograft model. Therefore, we hypothesized that the all oral combination of weekly SEL with standard Rd (i.e., SRd) could improve the efficacy compared with Rd in pts with RRMM and NDMM with acceptable toxicity profile.

Background:Selinexor (SEL) is a novel, first-in-class oral selective inhibitor of nuclear export (SINE) which blocks exportin 1 (XPO1), forcing the nuclear retention and activation of tumor suppressor proteins that cause cell cycle arrest and apoptosis in cancer cells. The combination of SEL with dexamethasone (dex), each administered twice weekly (BIW), received accelerated approval from the FDA in relapsed refractory multiple myeloma (RRMM). Subsequent evaluations of combination regimens have utilized once weekly (QW) SEL. The addition of oral SEL 100 mg QW to bortezomib also QW with dex (SVd) showed superior PFS and ORR with reduced peripheral neuropathy compared with standard BIW bortezomib plus dex (Dimopoulos et al. JCO2020).

Background:Once multiple myeloma (MM) becomes refractory to αCD38 mAb, pts have limited effective treatment options and poor prognoses. With standard therapies, overall response rate (ORR) to the first regimen after refractoriness to an αCD38 mAb is 31%, median progression-free survival (PFS) - 3.4 months and median overall survival (OS) - 9.3 months (Gandhi et al, Leukemia, 2019). Exportin 1 (XPO1) mediates the nuclear export and functional inactivation of tumor suppressor proteins. XPO1 is required for MM cell growth, is associated with poor prognosis and mediates resistance to standard MM and other anticancer therapies. Selinexor (SEL) is a first-in-class, oral selective inhibitor of nuclear export (SINE) compound approved for patients (pts) with previously treated MM as well as DLBCL. The doublet SEL-dexamethasone (Xd) achieved ORR ~26% in triple-class (Immunomodulatory drug [IMiD], proteosome inhibitor [PI], αCD38 mAb) refractory MM and improved OS over matched cohorts in community (Richardson et al, eJHaem, 2021) and academic (Cornell et al, AJH, 2020) settings. Hence, SEL-based triplets could be more effective in this triple class-treated population. We analyzed the efficacy and safety of SEL-containing triplets in pts in the STOMP study who were previously treated with regimens containing αCD38 mAb.

Introduction

Background

Background:Overexpression of the nuclear export protein exportin 1 (XPO1) mediates the functional inactivation of tumor suppressor proteins (TSPs), facilitates the export of oncogene mRNA thus facilitating oncoprotein expression, is associated with poor prognosis in multiple myeloma (MM), and contributes to immunomodulatory drug (IMiD) resistance. Selinexor is an oral, first-in-class, selective inhibitor of nuclear export (SINE) compound that by blocking XPO1 forces the nuclear retention and activation of TSPs and nuclear retention and inactivation of oncoproteins. 1Selinexor is approved with low-dose dexamethasone ± bortezomib for patients with previously treated MM. Pomalidomide plus dexamethasone (Pd) has an overall response rate (ORR) of ~30% and median PFS (mPFS) of ~4 months in patients with MM refractory to bortezomib and lenalidomide. We hypothesized that selinexor could be safely combined with Pd (XPd) and would improve the combination's efficacy.

Background:Clinical data support the combination of an immunomodulatory drug, a proteasome inhibitor, and a glucocorticoid for the treatment of newly diagnosed multiple myeloma (NDMM). The combination of lenalidomide, bortezomib, and low-dose dexamethasone is a very active, well-tolerated standard of care in the transplant-ineligible NDMM population. Ixazomib, an oral proteasome inhibitor is approved by the US Food and Drug Administration in combination with lenalidomide and dexamethasone for the treatment of relapsed MM. Given that ixazomib has improved binding kinetics and pharmacologic profile compared with bortezomib, it is expected that these differences will translate into similar, if not improved, efficacy and safety profiles in the upfront setting. A phase l/ll study of lenalidomide, ixazomib, and dexamethasone in previously untreated patients with MM demonstrated that this combination was well-tolerated and active (NCT01217957). More recently, the GRIFFIN study evaluated the addition of the anti-CD38 monoclonal antibody, daratumumab to lenalidomide, bortezomib, and dexamethasone in transplant-eligible NDMM and demonstrated the ability of daratumumab to improve efficacy of the three-drug combination with an acceptable safety profile. Building upon these data, our study evaluates the addition of daratumumab to the all-oral regimen of lenalidomide, ixazomib, and dexamethasone in transplant-ineligible NDMM. The combination proposed in this study has been evaluated in NDMM irrespective of transplant eligibility and has demonstrated excellent efficacy and tolerability. Responses were rapid with 88% achieving a partial response (PR) or better after 2 cycles (33% very good partial response (VGPR) and 52% VGPR for 29 patients who had completed 4 cycles) with an overall response rate of 95%. 1In our study, transplant-ineligible NDMM patients will be randomized to receive 12 cycles of induction with lenalidomide, ixazomib, dexamethasone, and daratumumab followed by lenalidomide alone versus lenalidomide, ixazomib, and daratumumab.

Introduction:Selinexor is a novel, oral selective inhibitor of nuclear export (SINE) which forces nuclear retention and activation of tumor suppressor proteins. Selinexor plus low dose dexamethasone (Sel-dex) was recently approved in the United States based on data from the STORM study wherein, Sel-dex induced an overall response rate (ORR) of 26.2% in patients with penta-exposed, triple-class refractory multiple myeloma. The presence of high-risk cytogenetic abnormalities is known to have a poor prognosis in multiple myeloma, with transient responses. We performed post-hoc analyses to determine the outcomes in patients with relapsed/refractory myeloma treated with Sel-dex based on the baseline cytogenetic abnormalities.

Introduction: Selinexor is a first-in-class Selective Inhibitor of Nuclear Export (SINE) compound that selectively binds and inactivates XPO1, therefore forcing the nuclear retention and re-activation of cell cycle regulators such as p53, FOXO, IkB, and Rb. Selinexor in combination with low dose dexamethasone (Sel-dex) was recently approved based on data from the STORM study, which induced an overall response rate (ORR) of 26.2% in patients with penta-exposed, triple-class refractory multiple myeloma (TCR-MM). Patients with TCR-MM often present with plasmacytomas along with serological markers of MM.
