New film-coated tablet formulation of deferasirox is well tolerated in patients with thalassemia or lower-risk MDS: Results of the randomized, phase II ECLIPSE study

Once-daily deferasirox dispersible tablets (DT) have a well-defined safety and efficacy profile and, compared with parenteral deferoxamine, provide greater patient adherence, satisfaction, and quality of life. However, barriers still exist to optimal adherence, including gastrointestinal tolerability and palatability, leading to development of a new film-coated tablet (FCT) formulation that can be swallowed with a light meal, without the need to disperse into a suspension prior to consumption. The randomized, open-label, phase II ECLIPSE study evaluated the safety of deferasirox DT and FCT formulations over 24 weeks in chelation-naïve or pre-treated patients aged ≥10 years, with transfusion-dependent thalassemia or IPSS-R very-low-, low-, or intermediate-risk myelodysplastic syndromes. One hundred seventy-three patients were randomized 1:1 to DT (n = 86) or FCT (n = 87). Adverse events (overall), consistent with the known deferasirox safety profile, were reported in similar proportions of patients for each formulation (DT 89.5%; FCT 89.7%), with a lower frequency of severe events observed in patients receiving FCT (19.5% vs. 25.6% DT). Laboratory parameters (serum creatinine, creatinine clearance, alanine aminotransferase, aspartate aminotransferase and urine protein/creatinine ratio) generally remained stable throughout the study. Patient-reported outcomes showed greater adherence and satisfaction, better palatability and fewer concerns with FCT than DT. Treatment compliance by pill count was higher with FCT (92.9%) than with DT (85.3%). This analysis suggests deferasirox FCT offers an improved formulation with enhanced patient satisfaction, which may improve adherence, thereby reducing frequency and severity of iron overload-related complications

Daratumumab for newly diagnosed multiple myeloma:Pooled analysis of patients aged ≥65 years from GRIFFIN and PERSEUS

Background: Older adults with newly diagnosed multiple myeloma (NDMM) have poor prognosis and constitute a subgroup of particular interest. In the GRIFFIN (NCT02874742) and PERSEUS (NCT03710603) studies, adding daratumumab to bortezomib/lenalidomide/dexamethasone (VRd) induction/consolidation and lenalidomide (R) maintenance deepened responses and improved progression-free survival (PFS) versus VRd/R in transplant-eligible patients with NDMM. Subgroup analyses of patients aged ≥65 years in PERSEUS demonstrated less pronounced PFS benefits (HRs: 0.97 [computerized algorithm]; 0.87 [independent review committee (IRC)]), potentially due to small event numbers, cytogenetic risk imbalances (high risk: D-VRd, 25.5%; VRd, 19.5%), and specific censoring rules. Here, we report results from a post hoc, pooled analysis of GRIFFIN and PERSEUS in patients aged ≥65 years (D-VRd, n = 122; VRd, n = 115). Methods: Using patient-level data, PFS analysis was evaluated per computerized algorithm in GRIFFIN and IRC in PERSEUS, stratified by International Staging System stage and cytogenetic risk, with no censoring of PFS events after ≥2 missing disease evaluations.Results: At a median follow-up of 49.6/47.5 months (GRIFFIN/PERSEUS), a trend in improved PFS was seen among patients aged ≥65 years favoring D-VRd (HR, 0.56 [95% CI, 0.30-1.01]). D-VRd improved rates of complete response or better (82.8% vs. 67.0%; OR, 2.37 [95% CI, 1.28-4.39]; P = .0046) and minimal residual disease negativity (10–5; 66.4% vs. 41.7%; OR, 2.75 [95% CI, 1.61-4.71]; P = .0002) versus VRd. No new safety concerns were identified. Conclusion: These data support use of D-VRd followed by D-R maintenance as standard of care for all transplant-eligible patients with NDMM, regardless of age up to 70 years.</p

A plain language summary of the final analysis of the GRIFFIN study of daratumumab plus lenalidomide, bortezomib, and dexamethasone for people with newly diagnosed multiple myeloma

WHAT IS THIS SUMMARY ABOUT?: This summary describes the final analysis of the GRIFFIN study. In this study, participants were newly diagnosed with a type of blood and bone marrow cancer called multiple myeloma, had never received any treatment, and were able to undergo an autologous stem cell transplant. The GRIFFIN study looked at adding the drug daratumumab (D) to a combination of standard treatments called RVd (lenalidomide [R], bortezomib [V], and dexamethasone [d]) during the treatment phases induction and consolidation, followed by daratumumab and lenalidomide (D-R) maintenance. Participants also received an autologous stem cell transplant to further help reduce multiple myeloma. The GRIFFIN study looked at whether D-RVd followed by D-R maintenance was better at killing multiple myeloma cells compared with RVd on its own followed by R maintenance on its own, and if treatments were safe. This summary also describes results from 2 other GRIFFIN publications: one that looked at participants with certain multiple myeloma characteristics or demographic factors that are associated with worse outcomes, and another that looked at how treatments impacted the participants' quality of life. WHAT WERE THE RESULTS?: At the time of the final analysis of GRIFFIN, participants who were treated with D-RVd followed by D-R maintenance had very low (undetectable) levels of multiple myeloma cells and multiple myeloma markers (biological signs) and were more likely to be alive without the multiple myeloma getting worse or coming back compared with participants who received standard RVd treatment followed by R maintenance. There was also a pattern of similar benefits achieved by participants who were at risk for worse outcomes. Additionally, participants who received D-RVd treatment followed by D-R maintenance reported less pain, less fatigue (extreme tiredness), and greater improvements in their ability to conduct daily physical activities. While some side effects (unwanted or unexpected effects of treatment) were higher with D-RVd, side effects in both groups were as expected, and adding daratumumab did not reduce a participant's ability to handle treatment. WHAT DO THE RESULTS OF THE STUDY MEAN?: Results of the GRIFFIN study showed that D-RVd treatment followed by D-R maintenance was better at treating multiple myeloma than the standard treatment of RVd followed by R maintenance in adults with a new diagnosis of multiple myeloma who were able to receive an autologous stem cell transplant, with no unexpected side effects of treatment.

Sleep disturbances in an arctic population: The Tromsø Study

<p>Abstract</p> <p>Background</p> <p>Prevalence estimates for insomnia range from 10 to 50% in the adult general population. Sleep disturbances cause great impairment in quality of life, which might even rival or exceed the impairment in other chronic medical disorders. The economic implications and use of health-care services related to chronic insomnia represent a clinical concern as well as a pronounced public health problem. Hypnotics are frequently prescribed for insomnia, but alcohol and over-the-counter sleep aids seem to be more widely used by insomniacs than prescription medications. Despite the complex relationship between insomnia and physical and mental health factors, the condition appears to be underrecognized and undertreated by health care providers, probably due to the generally limited knowledge of the causes and natural development of insomnia.</p> <p>Methods/Design</p> <p>The Tromsø Study is an ongoing population-based cohort study with five previous health studies undertaken between 1974 and 2001. This protocol outlines a planned study within the sixth Tromsø Study (Tromsø VI), aiming at; 1) describing sleep patterns in a community-based sample representative of the general population of northern Norway, and 2) examining outcome variables of sleep disturbances against possible explanatory and confounding variables, both within a cross-sectional approach, as well as retrospectively in a longitudinal study – exploring sleep patterns in subjects who have attended two or more of the previous Tromsø studies between 1974 and 2009. First, we plan to perform a simple screening in order to identify those participants with probable sleep disturbances, and secondly to investigate these sleep disturbances further, using an extensive sleep-questionnaire. We will also collect biological explanatory variables, i.e. blood samples, weight, height and blood pressure. We plan to merge data on an individual level from the Tromsø VI Study with data from the Norwegian Prescription Database (NorPD), which is a national registry including data for all prescription drugs issued at Norwegian pharmacies. Participants with sleep disturbances will be compared with pair-matched controls without sleep disturbances.</p> <p>Discussion</p> <p>Despite ongoing research, many challenges remain in the characterization of sleep disturbances and its correlates. Future mapping of the biological dimensions, natural history, as well as the behavioral and drug-related aspects of sleep disturbances in a representative population samples is clearly needed.</p

Metrics to assess the quantity of antibiotic use in the outpatient setting: a systematic review followed by an international multidisciplinary consensus procedure

Background The international Innovative Medicines Initiative (IMI) project DRIVE-AB (Driving Reinvestment in Research and Development and Responsible Antibiotic Use) aims to develop a global definition of ‘responsible’ antibiotic use. Objectives To identify consensually validated quantity metrics for antibiotic use in the outpatient setting. Methods First, outpatient quantity metrics (OQMs) were identified by a systematic search of literature and web sites published until 12 December 2014. Identified OQMs were evaluated by a multidisciplinary, international stakeholder panel using a RAND-modified Delphi procedure. Two online questionnaires and a face-to-face meeting between them were conducted to assess OQM relevance for measuring the quantity of antibiotic use on a nine-point Likert scale, to add comments or to propose new metrics. Results A total of 597 articles were screened, 177 studies met criteria for full-text screening and 138 were finally included. Twenty different OQMs were identified and appraised by 23 stakeholders. During the first survey, 14 OQMs were excluded and 6 qualified for discussion. During the face-to-face meeting, 10 stakeholders retained five OQMs and suggestions were made considering context and combination of metrics. The final set of metrics included defined daily doses, treatments/courses and prescriptions per defined population, treatments/courses and prescriptions per defined number of physician contacts and seasonal variation of total antibiotic use. Conclusions A small set of consensually validated metrics to assess the quantity of antibiotic use in the outpatient setting was obtained, enabling (inter)national comparisons. The OQMs will help build a global conceptual framework for responsible antibiotic use

Stem Cell Mobilization Yields with Daratumumab- and Lenalidomide-Containing Quadruplet Induction Therapy in Newly Diagnosed Multiple Myeloma: Findings from the MASTER and GRIFFIN Trials

For eligible patients with newly diagnosed multiple myeloma (NDMM), standard of care includes induction therapy followed by autologous stem cell transplantation (ASCT). Daratumumab as monotherapy and in combination treatment is approved across multiple lines of therapy for multiple myeloma (MM), and lenalidomide is an effective and commonly used agent for induction and maintenance therapy in MM. However, there is concern that lenalidomide and daratumumab given as induction therapy might impair mobilization of stem cells for ASCT. Therefore, we assessed stem cell mobilization in patients following frontline induction therapy in the MASTER and GRIFFIN phase 2 clinical studies by examining stem cell mobilization yields, apheresis attempts, and engraftment outcomes for patients from each study. Adult transplantation-eligible patients with NDMM received induction therapy consisting of daratumumab plus carfilzomib/lenalidomide/dexamethasone (D-KRd) for four 28-day cycles in the single-arm MASTER trial or lenalidomide/bortezomib/dexamethasone (RVd) with or without daratumumab (D) for four 21-day cycles in the randomized GRIFFIN trial, followed by stem cell mobilization and ASCT in both studies. Institutional practice differed regarding plerixafor use for stem cell mobilization; the strategies were upfront (ie, planned plerixafor use) or rescue (ie, plerixafor use only after mobilization parameters indicated failure with granulocyte colony-stimulating factor [G-CSF] alone). Descriptive analyses were used to summarize patient characteristics, stem cell mobilization yields, and engraftment outcomes. In MASTER, 116 D-KRd recipients underwent stem cell mobilization and collection at a median of 24 days after completing induction therapy. In GRIFFIN, 175 patients (D-RVd, n = 95; RVd, n = 80) underwent mobilization at a median of 27 days after completing D-RVd induction therapy and 24 days after completing RVd induction therapy. Among those who underwent mobilization and collection, 7% (8 of 116) of D-KRd recipients, 2% (2 of 95) of D-RVd recipients, and 6% (5 of 80) of RVd recipients did not meet the center-specific minimally required CD34+ cell yield in the first mobilization attempt; however, nearly all collected sufficient stem cells for ASCT on remobilization. Among patients who underwent mobilization, plerixafor use, either upfront or as a rescue strategy, was higher in patients receiving D-KRd (97%; 112 of 116) and D-RVd (72%; 68 of 95) compared with those receiving RVd (55%; 44 of 80). The median total CD34+ cell collection was 6.0 × 106/kg (range, 2.2 to 13.9 × 106/kg) after D-KRd induction, 8.3 × 106/kg (range, 2.6 to 33.0 × 106/kg) after D-RVd induction, and 9.4 × 106/kg (range, 4.1 to 28.7 × 106/kg) after RVd induction; the median days for collection were 2, 2, and 1, respectively. Among patients who underwent mobilization, 98% (114 of 116) of D-KRd patients, 99% (94 of 95) of D-RVd patients, and 98% (78 of 80) of RVd patients underwent ASCT using median CD34+ cell doses of 3.2 × 106/kg, 4.2 × 106/kg, and 4.8 × 106/kg, respectively. The median time to neutrophil recovery was 12 days in all 3 treatment groups across the 2 trials. Because both trials used different criteria to define platelet recovery, data on platelet engraftment using the same criteria are not available. Four cycles of daratumumab- and lenalidomide-based quadruplet induction therapy had a minimal impact on stem cell mobilization and allowed predictable stem cell harvesting and engraftment in all patients who underwent ASCT. Upfront plerixafor strategy may be considered, but many patients were successfully collected with the use of G-CSF alone or rescue plerixafor
