RESUMEN

Belumosudil, an investigational oral selective inhibitor of Rho-associated coiled-coil-containing protein kinase 2 (ROCK2), reduces type 17 and follicular T helper cells via downregulation of STAT3 and enhances regulatory T cells via upregulation of STAT5. Belumosudil may effectively treat patients with chronic graft-versus-host disease (cGVHD), a major cause of morbidity and late nonrelapse mortality after an allogeneic hematopoietic cell transplant. This phase 2 randomized multicenter registration study evaluated belumosudil 200 mg daily (n = 66) and 200 mg twice daily (n = 66) in subjects with cGVHD who had received 2 to 5 prior lines of therapy. The primary end point was best overall response rate (ORR). Duration of response (DOR), changes in Lee Symptom Scale score, failure-free survival, corticosteroid dose reductions, and overall survival were also evaluated. Overall median follow-up was 14 months. The best ORR for belumosudil 200 mg daily and 200 mg twice daily was 74% (95% confidence interval [CI], 62-84) and 77% (95% CI, 65-87), respectively, with high response rates observed in all subgroups. All affected organs demonstrated complete responses. The median DOR was 54 weeks; 44% of subjects have remained on therapy for ≥1 year. Symptom reduction with belumosudil 200 mg daily and 200 mg twice daily was reported in 59% and 62% of subjects, respectively. Adverse events (AEs) were consistent with those expected in patients with cGVHD receiving corticosteroids and other immunosuppressants. Sixteen subjects (12%) discontinued belumosudil because of possible drug-related AEs. Belumosudil, a promising therapy for cGVHD, was well tolerated with clinically meaningful responses. This trial was registered at www.clinicaltrials.gov as #NCT03640481.

RESUMEN

Carfilzomib, a proteasome inhibitor, is approved in the United States as a single agent, and in combination with dexamethasone or lenalidomide/dexamethasone (KRd) for relapsed or refractory multiple myeloma (MM). Under the single-agent and KRd approvals, carfilzomib is administered as a 10-minute IV infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles (20 mg/m(2) [cycle 1, days 1-2]; 27 mg/m(2) thereafter). This multicenter, single-arm, phase 1/2 study, Community Harmonized Assessment of Myeloma Patients via an Integrated Oncology Network-1 (CHAMPION-1), evaluated once-weekly carfilzomib with dexamethasone in relapsed, or relapsed and refractory MM (1-3 prior therapies). Patients received carfilzomib (30-minute IV infusion) on days 1, 8, and 15 of 28-day cycles. The phase 1 portion used a 3 + 3 dose-escalation scheme to determine the maximum tolerated dose (MTD) of carfilzomib. During phase 2, patients received carfilzomib on the same schedule at the MTD. Patients received dexamethasone (40 mg) on days 1, 8, 15, and 22; dexamethasone was omitted on day 22 for cycles 9+. A total of 116 patients were enrolled. The MTD was 70 mg/m(2), and 104 patients (phase 1/2) received carfilzomib 70 mg/m(2) At 70 mg/m(2), the median number of prior regimens was 1; and 52% were bortezomib-refractory. At 70 mg/m(2), the most common grade ≥3 adverse events were fatigue (11%) and hypertension (7%). Overall response rate at 70 mg/m(2) was 77%. Median progression-free survival was 12.6 months. These findings merit additional evaluation of the once-weekly dosing regimen. This trial was registered at www.clinicaltrials.gov as #NCT01677858.

RESUMEN

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. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT01080391.

RESUMEN

Despite the Netherlands' reputation as a world leader with respect to gay rights, homosexual Dutch men have much higher rates of mood disorders, anxiety disorders and suicide attempts than heterosexual Dutch men. Epidemiologists report similar disparities elsewhere in Western Europe and North America. These findings have been the focus of a blossoming psychological literature, inspired by minority stress theory and deploying quantitative methods. Our investigation aims to complement this body of work by adopting an ethnographic approach. Drawing from fieldwork conducted in the Netherlands from 2009 to 2010, we explore sociocultural and contextual factors that have received relatively little attention with respect to gay mental health. In the Netherlands - considered a model for gay equality - how can one understand high rates of psychiatric disorders among gay men? This study points to heteronormativity, complex dynamics involving long-term relationships and processes within gay subcultures as key issues. Notwithstanding their putative socioeconomic, legal and political equality, gay men struggled - at various stages of the life cycle - with internalised norms that they found difficult to fulfil. The desire to embody these ideals, and structural constraints in meeting them, could be potent sources of disappointment and distress.

RESUMEN

Chronic graft-versus-host disease (cGVHD) is a complication of hematopoietic cell transplantation (HCT). Although the clinical outcomes of cGVHD are well documented, few studies have assessed treatment practices outside of clinical trials. The present study aimed to quantify the prevalence of cGVHD, examine provider prescribing patterns, and evaluate the healthcare cost and resource utilization (HCRU) in a US cGVHD population. We analyzed anonymized claims from the Medicare Fee-for-Service (FFS) 5% sample for beneficiaries enrolled between 2013 and 2016 and PharMetrics commercial 2013 to 2018 databases to identify cGVHD in allogeneic HCT recipients. cGVHD was identified based on International Classification of Diseases Ninth/Tenth Revision diagnosis codes for cGVHD or unspecified GVHD with a first diagnosis >180 days post-HCT or a maintained unspecified GVHD diagnosis for >12 months postindex of unspecified GVHD diagnosis. Longitudinal and line of therapy (LOT) analyses were based on the PharMetrics dataset for 2013 to 2018. Healthcare costs were calculated by adding the inpatient, outpatient, and pharmacy insurer and beneficiary paid amounts for the commercially insured population. Total HCRU was assessed using the number of inpatient and outpatient visits following the initial cGVHD diagnosis. In 2016, the projected prevalence of cGVHD in the United States based on the Medicare FFS and PharMetrics commercial databases was 14,017 individual patients. Within 3 years after undergoing allogeneic HCT, 42% of patients developed cGVHD; 66% of the cGVHD patients had a prior diagnosis of acute GVHD. The majority of cGVHD patients received at least one systemic therapy; 71% and 47% of cGVHD patients progressed to a second and third LOT, respectively. A total of 24 unique therapeutic agents and more than 150 combinations were used in the second and third LOTs. Corticosteroids and corticosteroid combination therapy were the most common forms of treatment across all examined LOTs. Furthermore, the most commonly used agents in the first LOT, second LOT, and third LOT were corticosteroids only, calcineurin inhibitors only, and corticosteroids only, respectively. In the 12 months postdiagnosis, cGVHD patients had an average of 21.0 cGVHD-related inpatient and outpatient visits (2.8 inpatient and 18.2 outpatient visits). A significant proportion of allogeneic HCT recipients continue to develop cGVHD, and despite advances in the understanding of cGVHD, corticosteroids remain the mainstay of therapy. Patients often progress beyond the first LOT, at which time the utilization of systemic therapies is highly variable, demonstrating the need for evidence-based treatment approaches.

RESUMEN

PURPOSE: The rho-associated coiled-coil-containing protein kinase-2 (ROCK2) signaling pathway regulates the Th17/regulatory T cells balance and controls profibrotic pathways. Selective ROCK2 inhibition with belumosudil (KD025) may offer a novel approach to the management of chronic graft-versus-host disease (cGVHD). PATIENTS AND METHODS: A phase IIa, open-label, dose-finding study of belumosudil enrolled 54 patients with cGVHD who had received one to three prior lines of therapy (LOTs). The primary end point was overall response rate (ORR). RESULTS: The median time from cGVHD diagnosis to enrollment was 20 months. Seventy-eight percent of patients had severe cGVHD, 50% had ≥ 4 organs involved, 73% had cGVHD refractory to their last LOT, and 50% had received ≥ 3 prior LOTs. With an overall median follow-up of 29 months, the ORR (95% CI) with belumosudil 200 mg once daily, 200 mg twice daily, and 400 mg once daily was 65% (38% to 86%), 69% (41% to 89%), and 62% (38% to 82%), respectively. Responses were clinically meaningful, with a median duration of response of 35 weeks, and were associated with quality-of-life improvements and corticosteroid (CS) dose reductions. CS treatment was discontinued in 19% of patients. The failure-free survival rate was 76% (62% to 85%) and 47% (33% to 60%) at 6 and 12 months, respectively. The 2-year overall survival rate was 82% (69% to 90%). Belumosudil was well-tolerated, with low rates of cytopenia. There were no unexpected adverse events and no apparent increased risk of infection, including cytomegalovirus infection and reactivation. CONCLUSION: Belumosudil treatment resulted in a high ORR and overall survival rate and demonstrated quality-of-life improvements, CS dose reductions, and limited toxicity. Data from the study indicated that belumosudil may prove to be an effective therapy for patients with treatment-refractory cGVHD.

RESUMEN

A population pharmacokinetic (PK) model and exposure-response (E-R) analysis was developed using data collected from 5 phase 1b/2 and 2 phase 3 studies in subjects with multiple myeloma. Subjects receiving intravenous infusion on 2 consecutive days each week for 3 weeks (days 1, 2, 8, 9, 15, and 16) in each cycle at doses ranging from 15 to 20/56 mg/m2 (20 mg/m2 in cycle 1 and, if tolerated, escalated to 56 mg/m2 on day 8 of cycle 1). The population PK analysis indicated that among all the covariates tested, the only statistically significant covariate was body surface area on carfilzomib clearance; however, this covariate was unlikely to be clinically significant. Despite inclusion of different populations (relapsed or relapsed/refractory), treatments (carfilzomib monotherapy or combination therapy), infusion lengths (2 to 10 minutes or 30 minutes), and different doses, the E-R analysis of efficacy showed that after adjusting for baseline characteristics, higher area under the concentration-time curve was associated with improved overall response rate (ORR), from 15 to 20/56 mg/m2 . No positive relationships between maximum concentration and ORR were identified, indicating that ORR would not be expected to be impacted by infusion length. For safety end points, no statistically significant relationship between exposure and increasing risk of adverse events was identified. The results of an E-R analysis provided strong support for a carfilzomib dose at 20/56 mg/m2 as a 30-minute infusion for monotherapy and combination therapy. This article illustrates an example of application of E-R analysis to support labeling dose recommendation in the absence of extensive clinical data.

RESUMEN

OBJECTIVE: To assess the economic value of carfilzomib (Kyprolis), this study developed the Kyprolis Global Economic Model (K-GEM), which examined from a United States (US) payer perspective the cost-effectiveness of carfilzomib-lenalidomide-dexamethasone (KRd) versus lenalidomide-dexamethasone (Rd) in relapsed multiple myeloma (RMM; 1-3 prior therapies) based on results from the phase III ASPIRE trial that directly compared these regimens. METHODS: A partitioned survival model that included three health states of progression-free (on or off treatment), post-progression, and death was developed. Using ASPIRE data, the effect of treatment regimens as administered in the trial was assessed for progression-free survival and overall survival (OS). Treatment effects were estimated with parametric regression models adjusting for baseline patient characteristics and applied over a lifetime horizon. US Surveillance, Epidemiology and End Results (1984-2014) registry data were matched to ASPIRE patients to extrapolate OS beyond the trial. Estimated survival was adjusted to account for utilities across health states. The K-GEM considered the total direct costs (pharmacy/medical) of care for patients treated with KRd and Rd. RESULTS: KRd was estimated to be more effective compared to Rd, providing 1.99 life year and 1.67 quality-adjusted life year (QALY) gains over the modeled horizon. KRd-treated patients incurred $179,393 in total additional costs. The incremental cost-effectiveness ratio (ICER) was $107,520 per QALY. LIMITATIONS: Extrapolated survival functions present the greatest uncertainty in the modeled results. Utilities were derived from a combination of sources and assumed to reflect how US patients value their health state. CONCLUSIONS: The K-GEM showed KRd is cost-effective, with an ICER of $107,520 per QALY gained against Rd for the treatment of patients with RMM (1-3 prior therapies) at a willingness-to-pay threshold of $150,000. Reimbursement of KRd for patients with RMM may represent an efficient allocation of the healthcare budget.

RESUMEN

OBJECTIVE: The incidence of self-injurious behavior (SIB) in adolescent psychiatric inpatients has been reported to be as high as 61%, yet few data exist on the characteristics and functional role of SIB in this population. Because of the repetitive nature of SIB and its potential to increase in severity, features of SIB and its specific reinforcing effects were examined. METHOD: Participants were 42 self-injuring adolescents admitted to a hospital over a 4 month period. Data sources consisted of self-report questionnaires and medical chart review. RESULTS: Mean age was 15.7 +/- 1.5 years. Reported urges to self-injure were almost daily in 78.6% of the adolescents ( n= 33), with acts occurring more than once a week in 83.3% (n = 35). The two primary reasons endorsed for engaging in self-injury were "to cope with feelings of depression" (83.3%, n= 35) and "to release unbearable tension" (73.8%, n= 31). Of the sample, 97.6% ( n= 41) endorsed three or more addictive symptoms. CONCLUSIONS: SIB in hospitalized adolescents serves primarily to regulate dysphoric affect and displays many addictive features. Those with clinically elevated levels of internalized anger appear at risk for more addictive features of this behavior.

RESUMEN

BACKGROUND: To assess baseline characteristics, glycemic control, and treatment with oral antidiabetic drugs (OAD) in type 2 diabetes mellitus (T2DM) patients. METHODS: This multinational, observational study recruited patients ≥ 21 years of age who were newly diagnosed and/or treated with OAD monotherapy for <6 months but were inadequately controlled. In cross-sectional phase, data on demographics, medical history, diabetic complications and comorbidities, OAD treatment, glycosylated hemoglobin (HbA1c), and fasting blood glucose (FBG) were collected. In longitudinal phase evaluating 6-month follow-up of sulfonylurea (SU)-treated patients, additional data on reasons for not achieving HbA1c targets were collected. RESULTS: Of 1487 patients (mean [± SD] age 52.0 ± 11.6 years; 46.7% men; mean BMI 25.8 ± 4.4 kg/m(2) ) recruited, 75.9% were newly diagnosed, 73.3% had central obesity, 43.8% had hypertension, and 60.5% had dyslipidemia. The mean HbA1c was 9.8 ± 2.4%, and the mean FBG was 11.3 ± 4.3 mmol/L. At T0 (baseline) and T6 (month 6 visit), 99.8% (n=1066) and 97.1% (n=830) patients received SU, respectively. There was decrease from T0 to T6 in mean HbA1c (10.2% vs 7.3%, respectively; P<0.0001) and mean FBG (12.0 vs 7.6 mmol/L, respectively; P<0.0001). Number of patients with HbA1c <7% increased from T0 (4.5%) to T6 (46.8%). Reasons for not achieving target HbA1c included poor diabetes education (50.7%), non-compliance to OADs (21.4%), and fear of hypoglycemia (19.7%). CONCLUSION: Marked reductions in HbA1c and FBG are achievable in T2DM patients managed with OADs. However, patient education and compliance are important for achieving and maintaining treatment targets.

RESUMEN

Indians undergoing socioeconomic and lifestyle transitions will be maximally affected by epidemic of type 2 diabetes (T2D). We conducted a two-stage genome-wide association study of T2D in 12,535 Indians, a less explored but high-risk group. We identified a new type 2 diabetes-associated locus at 2q21, with the lead signal being rs6723108 (odds ratio 1.31; P = 3.32 × 10⁻9). Imputation analysis refined the signal to rs998451 (odds ratio 1.56; P = 6.3 × 10⁻¹²) within TMEM163 that encodes a probable vesicular transporter in nerve terminals. TMEM163 variants also showed association with decreased fasting plasma insulin and homeostatic model assessment of insulin resistance, indicating a plausible effect through impaired insulin secretion. The 2q21 region also harbors RAB3GAP1 and ACMSD; those are involved in neurologic disorders. Forty-nine of 56 previously reported signals showed consistency in direction with similar effect sizes in Indians and previous studies, and 25 of them were also associated (P < 0.05). Known loci and the newly identified 2q21 locus altogether explained 7.65% variance in the risk of T2D in Indians. Our study suggests that common susceptibility variants for T2D are largely the same across populations, but also reveals a population-specific locus and provides further insights into genetic architecture and etiology of T2D.

RESUMEN

OBJECTIVES: The VOICE Asia study aimed to establish the mode of thromboprophylaxis in medical patients admitted to intensive care units (ICU), and to describe the epidemiology of patients at high-risk of venous thromboembolism (VTE) and of patients who were prescribed low molecular weight heparin (LMWH). METHODS: This multinational, observational, cross-sectional study recruited medical patients admitted to ICU in whom a decision to give VTE prophylaxis had been taken. The treating physicians decided patient management. We recorded demographics, VTE risk factors, VTE risk assessment, thromboprophylaxis, and compliance to the American College of Chest Physicians (ACCP) guidelines. RESULTS: The study enrolled 2969 patients from 113 centers in 5 Asian countries. The most common VTE risk factors were age > 60 years (57.1%), prolonged immobility (50.6%), respiratory diseases (41.3%), and acute infectious disease (36.2%). There was a wide gap between physicians' assessment of 'very high' risk for VTE (8.4%) and Caprini 'very high' risk stratification (54.9%). 2919 (98.3%) patients received prophylaxis (22.9%-only mechanical, 31.2%-only pharmacological, 44.2%-both, mechanical and pharmacological and 1.7%- no prophylaxis). Early mobilization (44.3%) and LMWH (66.2%, mean duration of prophylaxis-8.6 days) were the most common mechanical and pharmacological prophylaxis, respectively. 80.6% of patients were given thromboprophylaxis as per the ACCP guidelines (and 4.7% per Japanese guidelines). CONCLUSIONS: There is substantial underestimation of VTE risk and non-adherence to guidelines for thromboprophylaxis in medical ICU patients in participating Asian countries. This emphasizes the need for increasing awareness about optimum VTE risk assessment and improved implementation of appropriate thromboprophylaxis in at-risk medical ICU patients.

RESUMEN

OBJECTIVE: To assess the difference in resource utilisation between lithium and valproate treatment groups from the VALID study. METHODS: A modelled economic study was conducted as an appendage to the VALID study, an international, randomised, open-label, parallel-group, 12-week, equivalence study in patients with bipolar I disorder experiencing a manic/mixed episode, compared the efficacy and safety of valproate against that of lithium. The difference in health resource utilisation between the treatment groups was analysed based on information collected from a standardised questionnaire. RESULTS: Efficacy and tolerability of valproate and lithium were shown to be comparable in the management of bipolar disorder in the VALID study. Cost analysis was based on information for 138 (35.5% male, mean age: 37.73 years) and 131 (45.8% male, mean age: 38.98 years) patients from lithium and valproate treatment groups, respectively. The groups differed in the number of hospital visits (503 vs. 421), outpatient visits (15 vs. 2), and number of work days lost (907 vs. 514.5) due to bipolar disorder. All differences were in favour of the valproate treatment group. In the modelled analysis and subsequent sensitivity analyses, the total cost saving was calculated to be US$199,322 (range: US$37,629-$226,903). This would translate into a cost saving of US$1444 per patient, or a cost saving of US$6278 per patient per year (range: US$1185-$7145 per patient per year). LIMITATIONS: The present study suffers from the limitations inherent in any economic evaluation that uses data from multicentre clinical trials with potential variations in treatment provision as well as the theoretical bias from an open-label study design. The study sample size had also limited statistical power to detect moderate differences in total medical costs, given the large variances often observed on cost variables. CONCLUSIONS: The use of valproate over lithium is likely to result in substantial cost savings to the healthcare system and reduce the financial burden to patients.
