RESUMEN
The presence of certain high-risk cytogenetic abnormalities, such as translocations (4;14) and (14;16) and deletion (17p), are known to have a negative impact on survival in multiple myeloma (MM). The phase 3 study ASPIRE (N = 792) demonstrated that progression-free survival (PFS) was significantly improved with carfilzomib, lenalidomide, and dexamethasone (KRd), compared with lenalidomide and dexamethasone (Rd) in relapsed MM. This preplanned subgroup analysis of ASPIRE was conducted to evaluate KRd vs Rd by baseline cytogenetics according to fluorescence in situ hybridization. Of 417 patients with known cytogenetic risk status, 100 patients (24%) were categorized with high-risk cytogenetics (KRd, n = 48; Rd, n = 52) and 317 (76%) were categorized with standard-risk cytogenetics (KRd, n = 147; Rd, n = 170). For patients with high-risk cytogenetics, treatment with KRd resulted in a median PFS of 23.1 months, a 9-month improvement relative to treatment with Rd. For patients with standard-risk cytogenetics, treatment with KRd led to a 10-month improvement in median PFS vs Rd. The overall response rates for KRd vs Rd were 79.2% vs 59.6% (high-risk cytogenetics) and 91.2% vs 73.5% (standard-risk cytogenetics); approximately fivefold as many patients with high- or standard-risk cytogenetics achieved a complete response or better with KRd vs Rd (29.2% vs 5.8% and 38.1% vs 6.5%, respectively). KRd improved but did not abrogate the poor prognosis associated with high-risk cytogenetics. This regimen had a favorable benefit-risk profile in patients with relapsed MM, irrespective of cytogenetic risk status, and should be considered a standard of care in these patients. This trial was registered at www.clinicaltrials.gov as #NCT01080391.

We performed analyses of the randomized phase 3 ASPIRE and ENDEAVOR trials to investigate the efficacy of carfilzomib among subgroups of relapsed or refractory multiple myeloma patients who had early or late disease relapse following initiation of the immediately prior therapy. In ASPIRE and ENDEAVOR, patients had received 1 to 3 prior lines of therapy. Patients in ASPIRE received carfilzomib, lenalidomide, and dexamethasone (KRd) or lenalidomide and dexamethasone (Rd), and patients in ENDEAVOR received carfilzomib and dexamethasone (Kd) or bortezomib and dexamethasone (Vd). Patients with relapse ≤1 year after initiating the most recent prior line of therapy were categorized as early relapsers, and patients with relapse after >1 year were categorized as late relapsers. The median progression-free survival (PFS) in ASPIRE for early relapsers was 21.4 months for KRd vs 10.7 months for Rd (hazard ratio [HR]: 0.714; 95% confidence interval [CI]: 0.508-1.004; P = 0.0257), and for late relapsers was 29.7 months for KRd vs 18.2 months for Rd (HR: 0.675; 95% CI: 0.533-0.854; P = 0.0005). The overall response rate (ORR) for early relapsers was 83.2% for KRd vs 54.8% for Rd, and for late relapsers was 89.0% for KRd vs 69.7% for Rd. The median PFS in ENDEAVOR (Kd vs Vd) for early relapsers was 13.9 months vs 5.7 months (HR: 0.598; 95% CI: 0.423-0.846; P = 0.0017), and for late relapsers was 22.2 months vs 10.2 months (HR: 0.486; 95% CI: 0.382-0.620; P < 0.0001). The ORR (Kd vs Vd) for early relapsers was 63.4% vs 49.1% and for late relapsers was 81.8% vs 66.8%. In conclusion, patients with relapsed or refractory multiple myeloma who received carfilzomib-containing regimens had improved PFS and ORR compared with control groups, regardless of whether they had an early or late relapse following the most recent prior therapy.

A primary analysis of the ASPIRE study found that the addition of carfilzomib to lenalidomide and dexamethasone (carfilzomib group) significantly improved progression-free survival (PFS) compared with lenalidomide and dexamethasone alone (control group) in patients with relapsed multiple myeloma (RMM). This post hoc analysis examined outcomes from ASPIRE in patients categorised by age. In the carfilzomib group, 103/396 patients were ≥70 years old, and in the control group, 115/396 patients were ≥70 years old. Median PFS for patients <70 years old was 28·6 months for the carfilzomib group versus 17·6 months for the control group [hazard ratio (HR), 0·701]. Median PFS for patients ≥70 years old was 23·8 months for the carfilzomib group versus 16·0 months for the control group (HR, 0·753). For patients <70 years the overall response rate (ORR) was 86·0% (carfilzomib group) and 66·9% (control group); for patients ≥70 years old the ORR was 90·3% (carfilzomib group) and 66·1% (control group). Within the carfilzomib group, grade ≥3 cardiovascular adverse events occurred more frequently among patients ≥70 years old compared with patients <70 years old. Carfilzomib-lenalidomide-dexamethasone has a favourable benefit-risk profile for patients with RMM, including elderly patients ≥70 years old.

OBJECTIVE: Several studies have suggested that bipolar disorder (BP) in adults is associated with aggressive behaviors. However, most studies have included only inpatients and have not taken into consideration possible confounding factors. The goal of the present study was to compare the prevalence of aggression in subjects with BP compared to subjects with other, non-BP psychopathology and healthy controls. METHODS: Subjects with bipolar I disorder (BP-I) and bipolar II disorder (BP-II) (n = 255), non-BP psychopathology (n = 85), and healthy controls (n = 84) were recruited. Aggression was measured using the Aggression Questionnaire (AQ). Group comparisons were adjusted for demographic and clinical differences (e.g., comorbid disorders) and multiple comparisons. The effects of the subtype of BP, current versus past episode, polarity of current episode, psychosis, the presence of irritable mania/hypomania only, and pharmacological treatment were examined. RESULTS: Subjects with BP showed significantly higher total and subscale AQ scores (raw and T-scores) when compared to subjects with non-BP psychopathology and healthy controls. Exclusion of subjects with current mood episodes and those with common comorbid disorders yielded similar results. There were no effects of BP subtype, polarity of the current episode, irritable manic/hypomanic episodes only, or current use of pharmacological treatments. Independent of the severity of BP and polarity of the episode, those in a current mood episode showed significantly higher AQ scores than those not in a current mood episode. Subjects with current psychosis showed significantly higher total AQ score, hostility, and anger than those without current psychosis. CONCLUSIONS: Subjects with BP display greater rates of anger and aggressive behaviors, especially during acute and psychotic episodes. Early identification and management of these behaviors is warranted.

OBJECTIVES: To compare the dimensional psychopathology in offspring of parents with bipolar disorder (BP) with offspring of community control parents as assessed by the Child Behavior Checklist (CBCL). METHODS: Offspring of parents with BP, who were healthy or had non-BP disorders (any psychiatric disorder other than BP; n = 319) or who had bipolar spectrum disorders (n = 35), and offspring of community controls (n = 235) ages 6-18 years were compared using the CBCL, the CBCL-Dysregulation Profile (CBCL-DP), and a sum of the CBCL items associated with mood lability. The results were adjusted for multiple comparisons and for any significant between-group demographic and clinical differences in both biological parents and offspring. RESULTS: With few exceptions, several CBCL (e.g., Total, Internalizing, and Aggression Problems), CBCL-DP, and mood lability scores in non-BP offspring of parents with BP were significantly higher than in offspring of control parents. In addition, both groups of offspring showed significantly lower scores in most scales when compared with offspring of parents with BP who had already developed BP. Similar results were obtained when analyzing the rates of subjects with CBCL T-scores that were two standard deviations or higher above the mean. CONCLUSIONS: Even before developing BP, offspring of parents with BP had more severe and higher rates of dimensional psychopathology than offspring of control parents. Prospective follow-up studies in non-BP offspring of parents with BP are warranted to evaluate whether these dimensional profiles are prodromal manifestations of mood or other disorders, and can predict those who are at higher risk to develop BP.

The regimen of carfilzomib, daratumumab, and dexamethasone (KdD) shows activity in patients with relapsed/refractory multiple myeloma. KdD at the twice-weekly 56 mg/m2 carfilzomib dose (KdD56) was used in the randomized phase 3 CANDOR study (NCT03158688), whereas KdD at the once-weekly 70 mg/m2 carfilzomib dose (KdD70) was used in the phase 1 b EQUULEUS study (NCT01998971). We analyzed efficacy data from comparable CANDOR and EQUULEUS patients using inverse probability of treatment weighting (IPTW)-adjusted models. These weights were calculated from propensity scores derived to balance prespecified baseline covariates. The side-by-side and adjusted comparisons showed similar efficacy for overall response rates and progression-free survival in the two groups, with a series of sensitivity analyses showing consistent findings. Safety data were generally consistent with the known safety profiles of each individual drug. Once-weekly KdD70 is comparable to twice-weekly KdD56 in terms of efficacy and safety while being a more convenient dosing option.

Frailty is most prevalent among elderly multiple myeloma (MM) patients, and frail patients have a higher risk of poor outcomes due to reduced performance status or comorbidities. This post hoc analysis assessed efficacy and safety of carfilzomib combinations in frail patients with relapsed and/or refractory MM from the phase 3 ASPIRE (carfilzomib [27 mg/m2]-lenalidomide-dexamethasone [KRd27] vs lenalidomide-dexamethasone [Rd]), ENDEAVOR (carfilzomib [56 mg/m2]-dexamethasone [Kd56] vs bortezomib-dexamethasone [Vd]), and ARROW (once-weekly carfilzomib [70 mg/m2]-dexamethasone [Kd70] vs carfilzomib [27 mg/m2]-dexamethasone [Kd27]) studies. A frailty algorithm incorporating age, Charlson comorbidity index, and performance status classified patients as fit, intermediate, or frail. Results are presented for frail patients (ASPIRE, n = 196; ENDEAVOR, n = 330; ARROW, n = 141). In ASPIRE, median progression-free survival (PFS) (hazard ratio; 95% confidence interval) was 24.1 (KRd27) vs 15.9 months (Rd) (0.78; 0.54-1.12); median overall survival (OS) was 36.4 vs 26.2 months (0.79; 0.57-1.08). In ENDEAVOR, median PFS was 18.7 (Kd56) vs 6.6 months (Vd) (0.50; 0.36-0.68); median OS was 33.6 vs 21.8 months (0.75; 0.56-1.00). In ARROW, median PFS was 10.3 (once-weekly Kd70) vs 6.6 months (twice-weekly Kd27) (0.76; 0.49-1.16). In all 3 studies, rates of grade ≥3 treatment-emergent adverse events were consistent with those observed in the primary studies. The ASPIRE, ENDEAVOR, and ARROW primary analyses demonstrated favorable benefit-risk profiles with carfilzomib-containing regimens compared with controls. Across clinically relevant subgroups, including those by frailty status, consistent efficacy and safety were observed with KRd27, Kd56, and weekly Kd70, and treatment with these regimens should not be restricted by frailty status.

PURPOSE: The oral proteasome inhibitor oprozomib has shown preclinical antitumor activity. Here, we report phase Ib/II study results investigating single-agent oprozomib in patients with relapsed multiple myeloma and Waldenström macroglobulinemia. PATIENTS AND METHODS: The primary objectives were to determine the MTD, safety, and tolerability of oprozomib (phase Ib) as well as overall response rate (ORR; phase II). Oprozomib was administered once daily on days 1, 2, 8, and 9 (2/7 schedule) or days 1 to 5 (5/14 schedule) of a 14-day cycle. RESULTS: In patients with multiple myeloma or Waldenström macroglobulinemia (n = 71), the determined MTDs were 300 mg/day (2/7 schedule) and 240 mg/day (5/14 schedule). Median oprozomib treatment duration for patients with multiple myeloma was 11.4 weeks (2/7 schedule, 240/300 mg/day), 5.4 weeks (5/14, 240 mg/day), and 10.1 weeks (5/14, 150/180 mg/day). For patients with Waldenström macroglobulinemia, these values were 34.6 weeks (2/7 schedule, 240/300 mg/day) and 8.1 weeks (5/14 schedule, 240 mg/day). The most common grade ≥3 adverse events (AE) in phase Ib included gastrointestinal and hematologic AEs. Three AE-related deaths in phase II prompted enrollment into 2/7 and 5/14 step-up dosing schedules (240/300 mg/day and 150/180 mg/day, respectively). In phase II, ORRs in 95 response-eligible multiple myeloma patients were 41.0%, 28.1%, and 25.0% in the 2/7, 240/300-mg/day; 5/14, 150/180-mg/day; and 5/14, 240-mg/day cohorts, respectively. ORRs in 31 response-eligible Waldenström macroglobulinemia patients were 71.4% and 47.1% for the 2/7 and 5/14 cohorts, respectively. CONCLUSIONS: This study demonstrated promising efficacy of single-agent oprozomib in patients with relapsed multiple myeloma and Waldenström macroglobulinemia.

BACKGROUND: In ASPIRE, carfilzomib, lenalidomide, and dexamethasone (KRd) significantly improved progression-free survival (PFS) and response rates versus lenalidomide and dexamethasone (Rd) in patients with relapsed multiple myeloma. Per protocol, patients received KRd for a maximum of 18 cycles followed by Rd to progression, so the benefit/risk profile of KRd to progression was not established. METHODS: This post hoc analysis evaluated the efficacy and safety of KRd versus Rd at 18 months from randomization. Cumulative rates of complete response (CR) or better over time and PFS hazard ratio (HR) at 18 months were evaluated for KRd versus Rd. PFS HRs were also assessed according to cytogenetic risk, prior lines of therapy, and prior bortezomib treatment. Cox regression analysis was used to evaluate PFS HRs. RESULTS: The hazard ratio (HR) for PFS at 18 months was 0.58 versus 0.69 for the overall ASPIRE study. Patients with high-risk cytogenetics, ≥ 1 prior lines of therapy, and prior bortezomib exposure benefited from KRd up to 18 months versus Rd. The HRs for PFS at 18 months in the pre-defined subgroups were lower than those in the overall study. The difference in the proportion of KRd and Rd patients achieving at least a complete response (CR) increased dramatically over the first 18 months and then remained relatively constant. The safety profile at 18 months was consistent with previous findings. CONCLUSIONS: The improved PFS HR at 18 months and the continued increase in CR rates for KRd through 18 cycles suggest that there may be a benefit of continued carfilzomib treatment.

Purpose In the ASPIRE study of carfilzomib, lenalidomide, and dexamethasone (KRd) versus lenalidomide plus dexamethasone (Rd) in patients with relapsed or refractory multiple myeloma, progression-free survival was significantly improved in the carfilzomib group (hazard ratio, 0.69; two-sided P < .001). This prespecified analysis reports final overall survival (OS) data and updated safety results. Patients and Methods Adults with relapsed multiple myeloma (one to three prior lines of therapy) were eligible and randomly assigned at a one-to-one ratio to receive KRd or Rd in 28-day cycles until withdrawal of consent, disease progression, or occurrence of unacceptable toxicity. After 18 cycles, all patients received Rd only. Progression-free survival was the primary end point; OS was a key secondary end point. OS was compared between treatment arms using a stratified log-rank test. Results Median OS was 48.3 months (95% CI, 42.4 to 52.8 months) for KRd versus 40.4 months (95% CI, 33.6 to 44.4 months) for Rd (hazard ratio, 0.79; 95% CI, 0.67 to 0.95; one-sided P = .0045). In patients receiving one prior line of therapy, median OS was 11.4 months longer for KRd versus Rd; it was 6.5 months longer for KRd versus Rd among patients receiving ≥ two prior lines of therapy. Rates of treatment discontinuation because of adverse events (AEs) were 19.9% (KRd) and 21.5% (Rd). Grade ≥ 3 AE rates were 87.0% (KRd) and 83.3% (Rd). Selected grade ≥ 3 AEs of interest (grouped terms; KRd v Rd) included acute renal failure (3.8% v 3.3%), cardiac failure (4.3% v 2.1%), ischemic heart disease (3.8% v 2.3%), hypertension (6.4% v 2.3%), hematopoietic thrombocytopenia (20.2% v 14.9%), and peripheral neuropathy (2.8% v 3.1%). Conclusion KRd demonstrated a statistically significant and clinically meaningful reduction in the risk of death versus Rd, improving survival by 7.9 months. The KRd efficacy advantage is most pronounced at first relapse.

BACKGROUND: Offspring of parents with bipolar disorder are at increased risk for a range of psychopathology, including bipolar disorder. It is not clear if they also have impairments in their psychosocial functioning. METHODS: We compared the psychosocial functioning of three groups of children enrolled in the Pittsburgh Bipolar Offspring Study (BIOS): offspring of probands with bipolar disorder (n=388), offspring of probands with other types of psychopathology (n=132), and offspring of healthy probands (n=118). Psychosocial functioning was assessed at study intake using the schedule of the Adolescent Longitudinal Interval Follow-Up Evaluation (A-LIFE), the Child Behavior Check List (CBCL) and the Children's Global Assessment Scale (CGAS). RESULTS: Offspring of probands with bipolar disorder exhibited impairments in various aspects of psychosocial functioning. On all measures, they had worse functioning in comparison with offspring of healthy probands. Offspring of probands with bipolar disorder generally exhibited more impairment than offspring of probands with nonbipolar psychopathology. After adjusting for proband parent functioning and the child's Axis I psychopathology, functioning of offspring of probands with bipolar disorder was similar to that of offspring of healthy probands. LIMITATIONS: Data are cross-sectional and therefore do not allow for causal conclusions about the association between parental psychopathology, child psychopathology and offspring psychosocial functioning. CONCLUSIONS: Offspring of parents with bipolar disorder exhibit impairments in psychosocial functioning which appear largely attributable to proband parent functional impairment and the child's own psychopathology. As such, interventions to improve parental functioning, as well as early interventions to treat the child's psychopathology may help reduce the risk for long-term functional impairment in offspring.

The objective of the study was to examine rates and identify risk factors for suicidal ideation among offspring of parents with bipolar disorder. Subjects included 388 offspring of parents with bipolar disorder and 250 offspring of matched community controls enrolled in the Pittsburgh Bipolar Offspring Study (BIOS). Offspring of bipolar probands displayed greater rates of lifetime suicidal ideation than offspring of controls (33% versus 20%). Factors most strongly associated with lifetime suicidal ideation in offspring of bipolar parents included offspring mood disorder, hostility, recent sexual abuse, and family conflict. Offspring of parents with bipolar disorder are at elevated risk for suicidal ideation as compared with offspring of controls. Suicide risk assessment in this population should attend to specific risk factors identified.

OBJECTIVE: The authors evaluated lifetime prevalence and specificity of DSM-IV psychiatric disorders and severity of depressive and manic symptoms at intake in preschool offspring of parents with bipolar I and II disorders. METHOD: A total of 121 offspring ages 2-5 years from 83 parents with bipolar disorder and 102 offspring of 65 demographically matched comparison parents (29 with non-bipolar psychiatric disorders and 36 without any lifetime psychopathology) were recruited for the study. Parents with bipolar disorder were recruited through advertisements and adult outpatient clinics, and comparison parents were ascertained at random from the community. Participants were evaluated with standardized instruments. All staff were blind to parental diagnoses. RESULTS: After adjustment for within-family correlations and both biological parents' non-bipolar psychopathology, offspring of parents with bipolar disorder, particularly those older than age 4, showed an eightfold greater lifetime prevalence of attention deficit hyperactivity disorder (ADHD) and significantly higher rates of having two or more psychiatric disorders compared to the offspring of the comparison parents. While only three offspring of parents with bipolar disorder had mood disorders, offspring of parents with bipolar disorder, especially those with ADHD and oppositional defiant disorder, had significantly more severe current manic and depressive symptoms than comparison offspring. CONCLUSIONS: Preschool offspring of parents with bipolar disorder have an elevated risk for ADHD and have greater levels of subthreshold manic and depressive symptoms than children of comparison parents. Longitudinal follow-up is warranted to evaluate whether these children are at high risk for developing mood and other psychiatric disorders.

CONTEXT: Whether offspring of parents with bipolar disorder (BP) are at specifically high risk to develop BP and other psychiatric disorders has not been adequately studied. OBJECTIVE: To evaluate lifetime prevalence and specificity of psychiatric disorders in offspring of parents with BP-I and BP-II. DESIGN: Offspring aged 6 to 18 years who have parents with BP and community control subjects were interviewed with standardized instruments. All research staff except the statistician were blind to parental diagnoses. SETTING: Parents with BP were recruited primarily through advertisement and outpatient clinics. Control parents were ascertained by random-digit dialing and were group matched for age, sex, and neighborhood to parents with BP. PARTICIPANTS: Three hundred eighty-eight offspring of 233 parents with BP and 251 offspring of 143 demographically matched control parents. MAIN OUTCOME MEASURES: Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I disorders. RESULTS: Adjusting for demographic factors, living with 1 vs both biological parents, both biological parents' non-BP psychopathology, and within-family correlations, offspring of parents with BP showed high risk for BP spectrum disorders (odds ratio [OR] = 13.4; 95% confidence interval [CI], 2.9-61.6) and any mood (OR = 5.2; 95% CI, 2.3-11.4), anxiety (OR = 2.3; 95% CI, 1.3-4.0), and Axis I (OR = 2.2; 95% CI, 1.5-3.3) disorders. Offspring of parents with BP with high socioeconomic status showed more disruptive behavior disorders and any Axis I disorders than offspring of control parents with high socioeconomic status. Families in which both parents had BP had more offspring with BP than families with only 1 parent with BP (OR = 3.6; 95% CI, 1.1-12.2). More than 75.0% of offspring who developed BP had their first mood episode before age 12 years, with most of these episodes meeting criteria for BP not otherwise specified and, to a lesser degree, major depression. CONCLUSIONS: Offspring of parents with BP are at high risk for psychiatric disorders and specifically for early-onset BP spectrum disorders. These findings further support the familiality and validity of BP in youth and indicate a need for early identification and treatment.
