Twice-weekly carfilzomib (27 mg/m2) plus lenalidomide and dexamethasone (KRd27) is a standard of care in relapsed/refractory multiple myeloma (RRMM). Once-weekly carfilzomib regimens have shown clinical benefits with improved patient convenience. This open-label, phase 3, multicenter, randomized study aimed to demonstrate noninferiority of the overall response rate (ORR) for once-weekly carfilzomib (56 mg/m2) plus Rd (KRd56) vs twice-weekly KRd27 in RRMM. A total of 454 patients were randomized (1:1) to receive carfilzomib as once-weekly 30-minute infusions of 56 mg/m2 (KRd56; n = 228) or twice-weekly 10-minute infusions of 27 mg/m2 (KRd27; n = 226). Baseline characteristics were balanced between groups. ORR was 82.5% (95% confidence interval [CI], 76.9-87.2) in the once-weekly group vs 86.3% (95% CI, 81.1-90.5) in the twice-weekly group (risk ratio, 0.954 [95% CI, 0.882-1.032]) and did not meet the threshold for statistical significance of noninferiority (P = .0666). Complete response (CR) or better was obtained in 46.9% of patients in the once-weekly arm and 36.3% in the twice-weekly arm. The proportions of patients who achieved CR and were also assessed negative for minimal residual disease were 21.5% and 18.1%, respectively (odds ratio, 1.235 [95% CI, 0.775-1.970]). Progression-free survival was comparable between groups (hazard ratio, 0.945 [95% CI, 0.617-1.447]). The safety profile was similar for both groups. In conclusion, although statistical significance for noninferiority of ORR was not achieved, the efficacy and safety of once-weekly KRd56 were similar to those of twice-weekly KRd27, and once-weekly KRd56 may be an effective and convenient treatment option for patients with RRMM. This trial was registered at www.ClinicalTrials.gov as #NCT03859427.

Drug delivery to central nervous pathologies is compromised by the blood-brain barrier (BBB). A clinically explored strategy to promote drug delivery across the BBB is sonopermeation, which relies on the combined use of ultrasound (US) and microbubbles (MB) to induce temporally and spatially controlled opening of the BBB. We developed an advanced in vitro BBB model to study the impact of sonopermeation on the delivery of the prototypic polymeric drug carrier pHPMA as a larger molecule and the small molecule antiviral drug ribavirin. This was done under standard and under inflammatory conditions, employing both untargeted and RGD peptide-coated MB. The BBB model is based on human cerebral capillary endothelial cells and human placental pericytes, which are co-cultivated in transwell inserts and which present with proper transendothelial electrical resistance (TEER). Sonopermeation induced a significant decrease in TEER values and facilitated the trans-BBB delivery of fluorescently labeled pHPMA (Atto488-pHPMA). To study drug delivery under inflamed endothelial conditions, which are typical for e.g. tumors, neurodegenerative diseases and CNS infections, tumor necrosis factor (TNF) was employed to induce inflammation in the BBB model. RGD-coated MB bound to and permeabilized the inflamed endothelium-pericyte co-culture model, and potently improved Atto488-pHPMA and ribavirin delivery. Taken together, our work combines in vitro BBB bioengineering with MB-mediated drug delivery enhancement, thereby providing a framework for future studies on optimization of US-mediated drug delivery to the brain.

The article presents a study of the effect of a modified fragment of neuropeptide Y (H-L-Ile-L-Asn-L-Leu-L-Nle-L-Ser- L-Arg-L-Asn-L-Arg-L-Tyr-NH2) named nonapeptide NP9 on the memory phases and extrapolation escape of animals. The study was performed in the passive avoidance test with intact animals, scopolamine-treated animals, and the extrapolation escape task. NP9 was investigated in the dose range of 0.04-0.4 mg/kg with a single intranasal administration. The comparison drug used peptide nootropic medicine Semax® (Met-Glu-His-Phe-Pro-Gly-Pro) at a dose of 0.1 mg/kg. Efficiency was assessed by the retention latency, the percentage of animals that have reached the learning criterion, the number of incomplete attempts to enter, the antiamnestic activity index calculated by Butlers formula, and the number of animals that successfully performed the extrapolation escape task. Peptide NP9 was superior to Semax® in most indicators. It demonstrated the ability to improve memorization due to its effect on I phase of memory and facilitated extinction of negative experiences when administered after a stress stimulus. NP9 also increased the cognitive ability of animals in the conditions an aversive environment in the extrapolation escape test. Thus, peptide NP9 is promising for a further study as a potential drug for the treatment of cognitive impairment and therapy of post-traumatic stress disorder.

Although proteasome inhibitors (PIs) are modern targeted anticancer drugs, they have been associated with a certain risk of cardiotoxicity and heart failure (HF). Recently, PIs have been combined with anthracyclines (ANTs) to further boost their anticancer efficacy. However, this raised concerns regarding cardiac safety, which were further supported by several in vitro studies on immature cardiomyocytes. In the present study, we investigated the toxicity of clinically used PIs alone (bortezomib (BTZ), carfilzomib (CFZ)) as well as their combinations with an ANT (daunorubicin (DAU)) in both neonatal and adult ventricular cardiomyocytes (NVCMs and AVCMs) and in a chronic rabbit model of DAU-induced HF. Using NVCMs, we found significant cytotoxicity of both PIs around their maximum plasma concentration (cmax) as well as significant augmentation of DAU cytotoxicity. In AVCMs, BTZ did not induce significant cytotoxicity in therapeutic concentrations, whereas the toxicity of CFZ was significant and more profound. Importantly, neither PI significantly augmented the cardiotoxicity of DAU despite even more profound proteasome-inhibitory activity in AVCMs compared with NVCMs. Furthermore, in young adult rabbits, no significant augmentation of chronic ANT cardiotoxicity was noted with respect to any functional, morphological, biochemical or molecular parameter under study, despite significant inhibition of myocardial proteasome activity. Our experimental data show that combination of PIs with ANTs is not accompanied by an exaggerated risk of cardiotoxicity and HF in young adult animal cardiomyocytes and hearts.

Autologous stem cell transplantation (ASCT) is a standard treatment for eligible multiple myeloma (MM) patients, but many patients will relapse after ASCT and require subsequent therapy. The proteasome inhibitor carfilzomib is approved for relapsed or refractory MM (RRMM). In phase 3 trials, carfilzomib-based regimens (ASPIRE, carfilzomib-lenalidomide-dexamethasone; ENDEAVOR, carfilzomib-dexamethasone) demonstrated superior progression-free survival (PFS) compared with standard therapies for RRMM (ASPIRE: lenalidomide-dexamethasone; ENDEAVOR, bortezomib-dexamethasone). This subgroup analysis of ASPIRE and ENDEAVOR evaluated outcomes according to prior ASCT status. In total, 446 patients in ASPIRE and 538 in ENDEAVOR had prior ASCT. Median PFS was longer for carfilzomib-based regimens vs non-carfilzomib-based regimens for patients with prior ASCT (ASPIRE: 26.3 vs 17.8 months (hazard ratio (HR)=0.68); ENDEAVOR: not estimable vs 10.2 months (HR=0.61)), those with one prior line of therapy that included ASCT (ASPIRE: 29.7 vs 17.8 months (HR=0.70); ENDEAVOR: not estimable vs 11.2 months (HR=0.46)), and those without prior ASCT (ASPIRE: 26.4 vs 16.6 months (HR=0.76); ENDEAVOR: 17.7 vs 8.5 months (HR=0.43)). Overall response rates also favored the carfilzomib-based regimens. No new safety signals were detected. This analysis suggests that carfilzomib-based treatment may lead to improvement in PFS and response rates regardless of prior transplant status. Further evaluation is warranted.

BACKGROUND: The phase 3 ENDEAVOR trial was a head-to-head comparison of two proteasome inhibitors in patients with relapsed or refractory multiple myeloma. Progression-free survival was previously reported to be significantly longer with carfilzomib administered in combination with dexamethasone than with bortezomib and dexamethasone in an interim analysis. The aim of this second interim analysis was to compare overall survival between the two treatment groups. METHODS: ENDEAVOR was a phase 3, open-label, randomised controlled trial in patients with relapsed or refractory multiple myeloma. Patients were recruited from 198 hospitals and outpatient clinics in 27 countries in Europe, North America, South America, and the Asia-Pacific region. Patients were aged 18 years or older, had relapsed or refractory multiple myeloma, and had received between one and three previous lines of therapy. Patients were randomly assigned (1:1) to receive carfilzomib and dexamethasone (carfilzomib group) or bortezomib and dexamethasone (bortezomib group) through a blocked randomisation scheme (block size of four), stratified by International Staging System stage, previous lines of treatment, previous proteasome inhibitor therapy, and planned route of bortezomib delivery if assigned to the bortezomib group. Carfilzomib (20 mg/m2 on days 1 and 2 of cycle 1; 56 mg/m2 thereafter) was given as a 30-min intravenous infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles; bortezomib (1·3 mg/m2) was given as an intravenous bolus or subcutaneous injection on days 1, 4, 8, and 11 of 21-day cycles. Dexamethasone (20 mg oral or intravenous infusion) was given on days 1, 2, 8, 9, 15, 16, 22, and 23 in the carfilzomib group and on days 1, 2, 4, 5, 8, 9, 11, and 12 in the bortezomib group. The primary endpoint of ENDEAVOR, progression-free survival, has been previously reported. A stratified log-rank test was used to compare overall survival between treatment groups for this prospectively planned second interim analysis. Efficacy assessments were done in all randomly assigned patients (the intention-to-treat population) and the safety analysis included patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01568866, and is no longer enrolling patients. FINDINGS: Between June 20, 2012, and June 30, 2014, 1096 patients were assessed for eligibility, of whom 929 were randomly assigned (464 to the carfilzomib group and 465 to the bortezomib group). The cutoff date for this prespecified interim analysis was Jan 3, 2017. Median overall survival was 47·6 months (95% CI 42·5-not evaluable) in the carfilzomib group versus 40·0 months (32·6-42·3) in the bortezomib group (hazard ratio 0·791 [95% CI 0·648-0·964], one-sided p=0·010). Grade 3 or worse adverse events were reported in 377 (81%) of 463 patients in the carfilzomib group and 324 (71%) of 456 patients in the bortezomib group, and serious adverse events in 273 (59%) patients in the carfilzomib group and 182 (40%) in the bortezomib group. The most frequent grade 3 or worse adverse events were anaemia (76 [16%] of 463 patients in the carfilzomib group vs 46 [10%] of 456 patients in the bortezomib group), hypertension (67 [15%] vs 15 [3%]), pneumonia (42 [9%] vs 39 [9%]), thrombocytopenia (41 [9%] vs 43 [9%]), fatigue (31 [7%] vs 35 [8%]), dyspnoea (29 [6%] vs ten [2%]), decreased lymphocyte count (29 [6%] vs nine [2%]), diarrhoea (18 [4%] vs 39 [9%]), and peripheral neuropathy (six [1%] vs 28 [6%]). Treatment-related deaths occurred in five (1%) of 463 patients in the carfilzomib group (pneumonia [n=2], interstitial lung disease [n=1], septic shock [n=1], and unknown [n=1]) and two (<1%) of 456 patients in the bortezomib group (cardiac arrest [n=1] and pneumonia [n=1]). INTERPRETATION: Carfilzomib provided a significant and clinically meaningful reduction in the risk of death compared with bortezomib. To our knowledge, carfilzomib is the first and only multiple myeloma treatment that extends overall survival in the relapsed setting over the current standard of care. This study is informative for deciding which proteasome inhibitor to use for treating this disease. FUNDING: Onyx Pharmaceuticals Inc, an Amgen Inc subsidiary.

The randomized phase 3 study ENDEAVOR demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) for carfilzomib and dexamethasone (Kd) vs bortezomib and dexamethasone (Vd) in relapsed or refractory multiple myeloma (MM). We conducted a preplanned subgroup analysis of ENDEAVOR to evaluate Kd vs Vd by cytogenetic risk. Of 785 patients with known cytogenetics, 210 (27%) had high-risk cytogenetics (Kd, n=97 (25%); Vd, n=113 (28%)) and 575 (73%) had standard-risk cytogenetics (Kd, n=284 (75%); Vd, n=291 (72%)). Median PFS in the high-risk group was 8.8 months for Kd vs 6.0 months for Vd (hazard ratio (HR), 0.65; 95% confidence interval (CI), 0.45-0.92; P=0.0075). Median PFS in the standard-risk group was not estimable for Kd vs 10.2 months for Vd (HR, 0.44; 95% CI, 0.33-0.58; P<0.0001). Overall response rates were 72.2% (Kd) vs 58.4% (Vd) in the high-risk group and 79.2% (Kd) vs 66.0% (Vd) in the standard-risk group. In the high-risk group, 15.5% (Kd) vs 4.4% (Vd) achieved a complete response (CR) or better. In the standard-risk group, 13.0% (Kd) vs 7.9% (Vd) achieved ⩾CR. This preplanned subgroup analysis found that Kd was superior to Vd in relapsed or refractory MM, regardless of cytogenetic risk.

UNLABELLED: 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.

Carfilzomib, a proteasome inhibitor, is approved as monotherapy and in combination with dexamethasone or lenalidomide-dexamethasone (Rd) for relapsed or refractory multiple myeloma. The approval of carfilzomib-lenalidomide-dexamethasone (KRd) was based on results from the randomized, phase 3 study ASPIRE (NCT01080391), which showed KRd significantly improved progression-free survival (PFS) vs Rd (median 26.3 vs 17.6 months; hazard ratio (HR)=0.690; P=0.0001). This subgroup analysis of ASPIRE evaluated KRd vs Rd by number of previous lines of therapy and previous exposure to bortezomib, thalidomide or lenalidomide. Treatment with KRd led to a 12-month improvement in median PFS vs Rd after first relapse (HR 0.713) and a 9-month improvement after ⩾2 previous lines of therapy (HR 0.720). Treatment with KRd led to an approximate 8-month improvement vs Rd in median PFS in bortezomib-exposed patients (HR 0.699), a 15-month improvement in thalidomide-exposed patients (HR 0.587) and a 5-month improvement in lenalidomide-exposed patients (HR 0.796). Objective response and complete response or better rates were higher with KRd vs Rd, irrespective of previous treatment. KRd had a favorable benefit-risk profile and should be considered an appropriate treatment option for patients with 1 or ⩾2 previous lines of therapy and those previously exposed to bortezomib, thalidomide or lenalidomide.
