BackgroundProteasome inhibitors (PIs), including carfilzomib, potentiate the activity of selinexor, a novel, first-in-class, oral selective inhibitor of nuclear export (SINE) compound, in preclinical models of multiple myeloma (MM).MethodsThe safety, efficacy, maximum-tolerated dose (MTD) and recommended phase 2 dose (RP2D) of selinexor (80 or 100 mg) + carfilzomib (56 or 70 mg/m2) + dexamethasone (40 mg) (XKd) once weekly (QW) was evaluated in patients with relapsed refractory MM (RRMM) not refractory to carfilzomib.ResultsThirty-two patients, median prior therapies 4 (range, 1–8), were enrolled. MM was triple-class refractory in 38% of patients and 53% of patients had high-risk cytogenetics del(17p), t(4;14), t(14;16) and/or gain 1q. Common treatment-related adverse events (all/Grade 3) were thrombocytopenia 72%/47% (G3 and G4), nausea 72%/6%, anaemia 53%/19% and fatigue 53%/9%, all expected and manageable with supportive care and dose modifications. MTD and RP2D were identified as selinexor 80 mg, carfilzomib 56 mg/m2, and dexamethasone 40 mg, all QW. The overall response rate was 78% including 14 (44%) ≥ very good partial responses. Median progression-free survival was 15 months.ConclusionsWeekly XKd is highly effective and well-tolerated. These data support further investigation of XKd in patients with MM.

A regimen of escalating doses of thalidomide, in combination with bortezomib and high-dose melphalan (mel/vel/thal), was evaluated as a conditioning regimen for autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients with a prior transplant who had relapsed or achieved less than a complete remission following a prior ASCT. Thalidomide was dose escalated starting from 600 mg to 1000 mg on days −5 to −1 in a 3 × 3 design, bortezomib was administered at 1.6 mg/m2 intravenously on days −4 and −1 and melphalan 200 mg/m2 was administered on day −2. No dose-limiting toxicity was seen in the phase I portion of the trial. An additional 20 patients were enrolled at the maximum tolerated dose of thalidomide of 1000 mg daily. The overall response rate was 69% with 38% complete remission. Median PFS and OS were 9.3 and 65.4 months, respectively, with a median follow-up of 17.8 months. The most common grade 3–4 adverse events (AEs) were neutropenic fever (58.6%), mucositis (6.9%), and diarrhea (6.9%). Serious AEs included somnolence (13.8%) and tumor lysis syndrome (3.4%). The addition of high-dose thalidomide to bortezomib and melphalan as conditioning for salvage ASCT was well tolerated and was an effective conditioning regimen.

Acute respiratory distress syndrome (ARDS) is a disorder that involves the activation of alveolar macrophages triggering the innate immune system. The parenchymal lung injury seen in ARDS is a result of many proinflammatory elevations including interleukin-6. There remains no effective standard of care of ARDS, and current treatments at this time currently do not target the immunological mechanisms or pathways involved. Treatments involving this pathway should be further investigated as targeted treatment. We discuss a case of a patient with multiple myeloma who was hospitalized with drug-induced ARDS who had a rapid response to an anti-interleukin-6 monoclonal antibody.

The treatment of newly diagnosed multiple myeloma (NDMM) has advanced rapidly in recent years, with the standard of care (SOC) now including not only triplet combinations of proteasome inhibitors (PIs), immunomodulatory agents, and steroids but also quadruplet combinations that add the anti‐CD38 monoclonal antibodies isatuximab (Isa) or daratumumab (D) to a triplet backbone. In addition to the widely used bortezomib–lenalidomide–dexamethasone (VRd) combination, an alternative triplet option that can be considered is the combination of the second‐generation PI carfilzomib (K) with lenalidomide–dexamethasone (KRd). In patients with transplant‐eligible NDMM, US treatment guidelines have included the KRd triplet as a recommended regimen and the quadruplet combinations of either Isa‐KRd or D‐KRd as additional options. However, currently, KRd does not have regulatory approval for use in the NDMM population. This review describes the current evidence for using KRd as a backbone of therapy in frontline treatment regimens for patients with NDMM. In addition to multiple studies that have examined the KRd triplet in this population, several clinical trials have been investigating anti‐CD38‐KRd quadruplets. The data reported from these various trials are revealing deep and durable responses with Isa‐KRd and D‐KRd, including minimal residual disease negativity. Importantly, these benefits have also been demonstrated in high‐risk NDMM populations. KRd‐based combinations may represent a suitable alternative to VRd for some patients. This article discusses measures that may help to establish KRd‐based quadruplets as an additional SOC in this setting, including proper patient selection, steps to mitigate safety concerns, and the establishment of optimal dosing schedules.

We assessed the safety, efficacy, maximum tolerated dose (MTD), and the recommended phase 2 dose (RP2D) of selinexor, a first in class oral selective inhibitor of nuclear export (100 mg once weekly [QW] or 60 mg twice weekly), in combination with daratumumab (16 mg/kg per label) and dexamethasone (40 mg QW) (SDd) in patients with relapsed refractory multiple myeloma (RRMM). Thirty‐four patients (median prior therapies, 3 [range, 2‐10]) were enrolled; MM was refractory to proteasome inhibitor (PI) in 85%, immunomodulatory agent (IMiD) in 76%, both in 74%, and daratumumab in 6% of patients. Two dose‐limiting toxicities (DLTs) were reported in the selinexor 60 mg twice‐weekly cohort with no DLTs in the 100 mg QW cohort, making 100 mg QW the MTD and RP2D. Common treatment‐related adverse events included thrombocytopenia (70.6%), nausea (70.6%), fatigue (61.8%), anemia (61.8%), and neutropenia (50.0%). Overall response rate was 73% and median progression‐free survival 12.5 months in daratumumab‐naïve patients. SDd was well tolerated and its promising efficacy suggests that further study of this PI‐ and IMiD‐free regimen in RRMM patients who had at least one prior line of therapy including a PI and an IMiD but whose disease is naïve to daratumumab is warranted.

We evaluated changes in patient‐reported outcomes and cognitive function from pre‐ to 3–6 months post‐treatment among 42 newly diagnosed patients with multiple myeloma undergoing transplant with complete data using PROMIS‐29. There were statistically significant improvements in physical (p < .001) and mental health (p < .001) but not cognition from pre‐treatment to 3–6 month follow‐up. Similar results were seen within age or comorbidity strata. Patients with myeloma undergoing transplant experienced generally improved short‐term health outcomes with no significant declines in cognition.

Triple‐class‐refractory multiple myeloma (MM) describes MM refractory to proteasome inhibitors, immunomodulatory agents, and anti‐CD38 monoclonal antibodies. In the Phase IIb STORM study (NCT02336815), oral selinexor plus low‐dose dexamethasone (Sel‐dex) demonstrated a 26.2% overall response rate in triple‐class‐refractory MM. Here, we compare overall survival (OS) of 122 patients with triple‐class‐refractory MM who received Sel‐dex in STORM Part 2 with that of 64 similar patients treated with other available therapies in a Flatiron Health Analytic Database (FHAD) cohort. OS from the date that the patients’ MM became triple‐class‐refractory was longer in STORM versus FHAD, with an unadjusted hazard ratio (HR) of 0.43 (P =  .0002; adjusted HR 0.35 [P  =  .011]). In a subset analysis of highly resistant patients receiving further therapies after their MM first became at least triple‐class‐refractory (i.e., who received Sel‐dex in STORM, n = 64, and non‐Sel‐dex in FHAD, n = 36), the OS was significantly longer in STORM with an unadjusted HR of 0.52 (P = .0331; adjusted HR 0.33 [P = .041]). Within the limits of this analysis, the OS of patients with at least triple‐class‐refractory MM was significantly better with Sel‐dex versus available therapies, suggesting that Sel‐dex may be associated with a meaningful OS benefit in these patients.

Multiple myeloma (MM) is a heterogeneous hematologic malignancy associated with several risk factors including genetic aberrations which impact disease response and survival. Thorough risk classification is essential to select the best clinical strategy to optimize outcomes. The SKY92 molecular signature classifies patients as standard‐ or high‐risk for progression. The PRospective Observational Multiple Myeloma Impact Study (PROMMIS; NCT02911571) measures impact of SKY92 on risk classification and treatment plan. Newly diagnosed MM patients had bone marrow aspirates analyzed for SKY92. Physicians completed a questionnaire for each patient capturing risk classification, hypothetical treatment plan, and physician confidence in the treatment plan, before and after unblinding SKY92. One hundred forty seven MM patients were enrolled. Before unblinding SKY92, physicians regarded 74 (50%) patients as clinical standard‐risk. After unblinding SKY92, 16 patients were re‐assigned as high‐risk by the physician, and for 15 of them treatment strategy was impacted, resulting in an escalated treatment plan. For the 73 (50%) clinical high‐risk patients, SKY92 indicated 46 patients to be standard‐risk; for 31 of these patients the treatment strategy was impacted consistent with a de‐escalation of risk. Overall, SKY92 impacted treatment decisions in 37% of patients (p < 0.001). For clinical decision‐making, physicians incorporated SKY92, and the final assigned clinical risk was in line with SKY92 for 89% of patients. Furthermore, SKY92 significantly increased the confidence of the physicians’ treatment decisions (p < 0.001). This study shows potential added value of SKY92 in MM for treatment decision making.

\"In the general population, adherence to healthy lifestyle behaviors - including regular exercise - is associated with substantial reductions in cardiovascular disease mortality and mortality from any cause,\" Jessica M. Scott, PhD, principal investigator in Lee Jones Lab at Memorial Sloan Kettering Cancer Center, and colleagues wrote. Whether these findings extend to adult survivors of childhood cancer with excess risk of mortality is not known\" Scott and colleagues performed a multicenter cohort analysis of 15,450 adults (median age at interview, 25.9 years; 52.8% men) enrolled in the Childhood Cancer Survivor Study, all of whom were diagnosed at age younger than 21 years between 1970 and 1999. Among a subset of 5,869 survivors, increased exercise (mean, 7.9 metabolic-equivalent task hours per week) appeared associated with a 40% reduction in all-cause mortality rate over the course of 8 years compared with maintenance of low exercise levels.
