RESUMO

OBJECTIVE: To evaluate the safety, tolerability, and effect of fezolinetant on endometrial health over 52 weeks. METHODS: We conducted a phase 3, randomized, double-blind, 52-week safety study (SKYLIGHT 4 [Study to Find Out How Safe Long-term Treatment With Fezolinetant is in Women With Hot Flashes Going Through Menopause]) of placebo, fezolinetant 30 mg, and fezolinetant 45 mg once daily (1:1:1). Participants were postmenopausal and seeking treatment for vasomotor symptoms associated with menopause. Primary endpoints were treatment-emergent adverse events, percentage of participants with endometrial hyperplasia, and percentage with endometrial malignancy. Endometrial hyperplasia or malignancy was evaluated according to U.S. Food and Drug Administration guidance (point estimate of 1% or less with an upper bound of one-sided 95% CI of 4% or less). Secondary endpoints included change in bone mineral density (BMD) and trabecular bone score. A sample size of 1,740 was calculated to enable observation of one or more events (≈80% probability for events with background rate of less than 1%). RESULTS: A total of 1,830 participants were randomized and took one or more medication dose (July 2019-January 2022). Treatment-emergent adverse events occurred in 64.1% (391/610) of the placebo group, 67.9% (415/611) of the fezolinetant 30-mg group, and 63.9% (389/609) of the fezolinetant 45-mg group. Treatment-emergent adverse events leading to discontinuation were similar across groups (placebo, 26/610 [4.3%]; fezolinetant 30 mg, 34/611 [5.6%]; fezolinetant 45 mg, 28/609 [4.6%]). Endometrial safety was assessed in 599 participants. In the fezolinetant 45-mg group, 1 of 203 participants had endometrial hyperplasia (0.5%; upper limit of one-sided 95% CI 2.3%); there were no cases in the placebo (0/186) or fezolinetant 30 mg (0/210) group. Endometrial malignancy occurred in 1 of 210 in the fezolinetant 30-mg group (0.5%; 95% CI 2.2%) with no cases in the other groups. Liver enzyme elevations more than three times the upper limit of normal occurred in 6 of 583 placebo, 8 of 590 fezolinetant 30 mg, and 12 of 589 fezolinetant 45 mg participants; no Hy's law cases were reported (ie, no severe drug-induced liver injury with alanine aminotransferase or aspartate aminotransferase more than three times the upper limit of normal and total bilirubin more than two times the upper limit of normal, with no elevation of alkaline phosphatase and no other reason to explain the combination). Changes in BMD and trabecular bone score were similar across groups. CONCLUSION: Results from SKYLIGHT 4 confirm the 52-week safety and tolerability of fezolinetant and support its continued development. FUNDING SOURCE: Astellas Pharma Inc.

RESUMO

BACKGROUND AND AIM: The Patient-Generated Subjective Global Assessment (PG-SGA©) is a globally used malnutrition screening, assessment, triage and monitoring tool. The aim of this study was to perform a linguistic and content validation of the translated and culturally adapted version of the PG-SGA for the Danish setting. METHOD: The study was conducted according to the International Society of Pharmaeconomics and Outcomes Research (ISPOR) Principles of Good Practice for the Translational and Cultural Adaptation Process for Patient-Reported Outcomes Measures. Cancer patients (n = 121) and healthcare professionals (HCPs, n = 80) participated in the cognitive debriefing. A questionnaire was used in the cognitive debriefing in which comprehensibility, difficulty, and content validity (relevance) were quantified by a 4-point scale. Item and scale indices were calculated using the average item ratings divided by the number of respondents for content validity (Item-CVI, Scale-CVI), comprehensibility (Item-CI, Scale-CI) and difficulty (Item-DI, Scale-DI). As pre-defined, item indices <0.78 required further analysis of the item, and scale indices ≥0.90 were defined as excellent and 0.80-0.89 as acceptable. RESULTS: The patient component of the PG-SGA was rated as excellent content validity (Scale-CVI = 0.95) by HCPs and easy to comprehend (Scale-CI = 0.97) and use (Scale-DI = 0.92) by patients. The professional component of the PG-SGA was rated as acceptable content validity (Scale-CVI = 0.80), but below acceptable for comprehension (Scale-CI = 0.71) and difficulty (Scale-DI = 0.69). The physical exam was rated the least comprehensible Item-CI = 0.51-0.70) and most difficult (Item-DI = 0.33-0.063). CONCLUSION: The PG-SGA was successfully translated and culturally adapted to the Danish setting. Patients found it easy to understand and to complete. Except for the physical exam, HCPs rated the PG-SGA as relevant, comprehensive, and easy to use. Training of HCPs is recommended before implementing the tool into clinical practise.

RESUMO

PURPOSE: To evaluate the pharmacodynamics (PD), pharmacokinetics (PK), and safety of single and multiple doses of PF-06881894 (pegfilgrastim-apgf; Nyvepria™), a biosimilar to reference pegfilgrastim (Neulasta®), in women with non-distantly metastatic breast cancer. METHODS: In Phase I (Cycle 0) of this Phase I/II study, the PD response (absolute neutrophil count [ANC]; CD34 + count), PK profile, and safety of a single 3- or 6-mg subcutaneous dose of PF-06881894 were assessed in chemotherapy-naïve patients before definitive breast surgery. In Phase II (Cycles 1-4), the PD response (duration of severe neutropenia [DSN, Cycle 1], ANC [Cycles 1 and 4]) and PK profile (Cycles 1 and 4) of single and multiple 6-mg doses of PF-06881894 concomitant with chemotherapy and after definitive breast surgery were assessed. RESULTS: Twenty-five patients (mean age 59 years) were enrolled (Cycle 0, n = 12; Cycles 1-4, n = 13). In Cycle 0, PD responses and PK values were lower with 3-mg versus 6-mg PF-06881894. In Cycles 1 and 4, mean DSN was 0.667 days after single or multiple 6-mg doses of PF-06881894, respectively. In Cycle 4 versus Cycle 1, PD responses were more robust; PK values (mean area under the curve, maximum concentration) were lower; and clearance values were higher. The safety profile of PF-06881894 was similar to that for reference pegfilgrastim. CONCLUSION: PF-06881894 as a single 3- or 6-mg dose prior to definitive surgery, or multiple 6-mg/cycle doses postoperatively, with/without myelosuppressive chemotherapy, was consistent with the clinical pharmacology and safety profile of reference pegfilgrastim.

RESUMO

BACKGROUND AND AIMS: Patients with cancer frequently present with disease-related malnutrition and functional decline. The scored Patient-Generated Subjective Global Assessment (PG-SGA©) is a malnutrition screening and assessment tool commonly used in patients with cancer. The aim of the current study was to translate and culturally adapt the original English PG-SGA for the Greek setting, including assessment of comprehensibility, difficulty and content validity in patients and healthcare professionals. METHODS: Our study was conducted according to the ten steps of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Principles of Good Practice for Translation and Cultural Adaptation. Comprehensibility and difficulty of the Greek translation were assessed in 100 patients and 100 healthcare professionals (HCPs) from Greece. Content validity of the translation was assessed among HCPs. Item and scale indices were calculated for comprehensibility (I-CI; S-CI), difficulty (I-DI; S-DI), and content validity (I-CVI; S-CVI). RESULTS: Patient perceived comprehensibility and difficulty of the PG-SGA were considered to be excellent (S-CI = 0.97, S-DI = 0.97). HCPs perceived content validity for the patient component was also excellent (S-CVI = 0.95). The perceived content validity, comprehensibility and difficulty for the professional component of the PG-SGA, as perceived by the HCPs, was excellent (S-CVI = 0.94, S-CI = 0.94, S-DI = 0.90), with the physical exam being perceived as most difficult (I-DI = 0.78-0.92). CONCLUSIONS: Our study resulted in the successful translation and cross-cultural adaptation of the original English PG-SGA for the Greek setting. The Greek language version of the PG-SGA is characterized by high comprehensibility, low difficulty, and is considered relevant for use in Greece.

RESUMO

PURPOSE: The Scored Patient-Generated Subjective Global Assessment (PG-SGA©) is a globally recognized and used nutritional screening, assessment, monitoring, and triaging tool. The aim of this study was to translate and culturally adapt the original English PG-SGA for the Japanese speaking populations and to assess its linguistic validity (i.e., comprehensibility, difficulty) and content validity, as perceived by Japanese patients and healthcare professionals. METHODS: In accordance with methodology used in previous Dutch, Thai, German, and Norwegian PG-SGA studies, we followed the ten steps of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Principles of Good Practice for Translation and Cultural Adaptation for Patient-Reported Outcome Measures. The study enrolled 50 patients and 50 healthcare professionals (HCPs) to evaluate the comprehensibility and difficulty of the translated and culturally adapted PG-SGA. The HCPs also evaluated the content validity of the translation. We evaluated each item and quantified scale indices for content validity (item content validity index (I-CVI), scale content validity index (S-CVI)), comprehensibility (item comprehensibility index (I-CI), scale comprehensibility index (S-CI)), and difficulty (item difficulty index (I-DI), scale difficulty index (S-DI)). RESULTS: Patients evaluated the comprehensibility and difficulty of the patient component as excellent (S-CI = 0.97, S-DI = 0.96). The professionals rated the Japanese version of both components of the PG-SGA as very relevant (S-CVI = 0.94). The professionals evaluated the comprehensibility of the professional component as being acceptable (S-CI = 0.88) but difficult (S-DI = 0.69), based predominantly on items related to physical examination (I-DI = 0.33-0.67). CONCLUSION: The PG-SGA was systematically translated and culturally adapted for the Japanese setting according to the ISPOR process. The Japanese version of the PG-SGA was perceived as comprehensive, easy to use, and relevant. Perceived difficulty in professional components, specifically in the context of metabolic demand and physical examination, will require appropriate training for professionals in order to optimize implementation.

RESUMO

BACKGROUND & AIMS: The Scored Patient-Generated Subjective Global Assessment (PG-SGA©) is a validated nutritional screening, assessment, monitoring, and triage tool. When translated to other languages, the questions and answering items need to be conceptually, semantically, and operationally equivalent to the original tool. In this study, we aimed to assess linguistic and content validity of the PG-SGA translated and culturally adapted for the Norwegian setting, as perceived by Norwegian cancer patients and healthcare professionals (HCPs). METHODS: We have translated and culturally adapted the original PG-SGA for the Norwegian setting, in concordance with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Cancer patients and HCPs, including nurses, dietitians and physicians, were invited to participate. Comprehensibility and difficulty were assessed by patients for the patient component (PG-SGA Short Form), and by HCPs for the professional component. Content validity was assessed for the full PG-SGA by HCPs only. The data were collected by a questionnaire and evaluations were operationalized by a 4-point scale. Item and scale indices were calculated for comprehensibility (Item CI, Scale CI), difficulty (Item DI, Scale DI) and content validity (Item CVI, Scale CVI). RESULTS: Fifty-one cancer patients and 92 HCPs participated in the study. The patients perceived comprehensibility and difficulty of the Norwegian PG-SGA Short Form as excellent (Scale CI = 0.99 and DI = 0.97). However, HCPs perceived comprehensibility and difficulty of the professional component as below acceptable (Scale CI = 0.78 and DI = 0.66), and the physical exam was being rated as the most difficult part (Item DI 0.26 to 0.65). Content validity for the full Norwegian PG-SGA was considered excellent (Scale CVI = 0.99) by the HCPs. CONCLUSION: The patient component of PG-SGA was considered clear and easy to complete, and the full Norwegian PG-SGA was considered as relevant by HCPs. In the final Norwegian PG-SGA, changes have been made to improve comprehensibility of the professional component. To improve perceived difficulty of completing the professional component, training of professionals is indicated.

RESUMO

BACKGROUND: We aimed to assess feasibility of self-completion of the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) by head and neck cancer patients, and to assess self-reported increased awareness regarding malnutrition risk after self-completion. METHODS: Participants were randomized to complete the PG-SGA SF by paper or app. Feasibility was assessed by time needed to complete the PG-SGA SF, perceived difficulty, and help needed during completion. Participants were asked if they knew what malnutrition was (yes/no) and if they could define "malnutrition." They were also asked 9 questions on whether they perceived increased awareness of malnutrition risk after having completed the PG-SGA SF and 2 on their intention to change lifestyle habits. RESULTS: Of all participants (n = 59; 65.9 ± 12.6 years; 73% male), 55% completed the PG-SGA SF paper version and 46% the Pt-Global app. Median time needed for self-completion of the PG-SGA SF was 2 minutes 41 seconds (interquartile range: 1 minute 49 seconds-3 minutes 50 seconds). Forty-eight percent needed help with completion, indicating acceptable feasibility. Participants who completed the Pt-Global app needed help significantly more often (66%; 21/32) than those who completed the PG-SGA SF paper version (26%; 7/27) (P = 0.005). All difficulty scores were excellent. For 7/9 questions on malnutrition risk awareness, >50% of the participants answered positively. CONCLUSION: The results of this study show that self-completion of the PG-SGA SF by head and neck cancer patients is feasible and that awareness regarding malnutrition risk may increase after completing the PG-SGA SF.

RESUMO

The ideal tool for determination of malnutrition risk or malnutrition in long term care (LTC) is elusive. This study compares prevalence, association with resident risk factors and sensitivity (SE) and specificity (SP) of malnutrition or risk categorization in 638 residents from 32 LTC homes in Canada using four tools: the Mini-Nutritional Assessment Short Form (MNA-SF); Patient-Generated Subjective Global Assessment (PG-SGA) Global Category Rating and the Pt-Global webtool; and the interRAI Long Term Care Facility undernutrition trigger. Prevalence was most common with MNA-SF (53.7%) and lowest with InterRAI (28.9%), while the PG-SGA Global Category Rating (44%) was higher than the Pt-Global webtool (33.4%). Tools were consistently associated with resident covariates with few exceptions. The PG-SGA Global Category Rating demonstrated the best sensitivity and specificity when compared to all other tools. Further work to determine the predictive validity of this tool in LTC residents is required.

RESUMO

PURPOSE: The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is the only malnutrition (risk) assessment tool that combines patient-generated measures with professional-generated (medical) factors. We aimed to apply international standards to produce a high quality, validated, translation and cultural adaptation of the original PG-SGA for the Austrian, German, and Swiss setting. METHODS: Analogue to methodology used for the Dutch, Portuguese, and Thai versions of PG-SGA, the ten steps of the International Society for Pharmacoeconomics and Outcomes Research's principles of good practice for translation and cultural adaptation were followed. Comprehensibility and difficulty of the translation were assessed in 103 patients and 104 healthcare professionals recruited from all three German-speaking countries. Content validity of the translation was assessed among healthcare professionals (HCP). Item and scale indices were calculated for content validity (I-CVI; S-CVI), comprehensibility (I-CI; S-CI), and difficulty (I-DI; S-DI). RESULTS: Patients' perceived comprehensibility and difficulty of the PG-SGA fell within the range considered to be excellent (S-CI = 0.90, S-DI = 0.90), HCP-perceived content validity (S-CVI = 0.90) was also excellent, while HCP-perceived comprehensibility fell within the high range of acceptable (S-CI = 0.87). The professional component of the PG-SGA was perceived as below acceptable (S-DI = 0.72) with the physical exam being rated the most difficult (I-DI=0.29-0.75). CONCLUSIONS: The systematic approach resulted in a high-quality validation of the German language version of the PG-SGA, that is internationally comparable, comprehensible, easy to complete, and considered relevant for use in Austria, Germany and Switzerland.

RESUMO

BACKGROUND: Assessment of malnutrition is important in cancer patients. The Scored Patient-Generated Subjective Global Assessment (PG-SGA), an instrument that enables interdisciplinary assessment of malnutrition and its risk factors, was not available in Dutch. OBJECTIVE: Translation and cultural adaption of the original English PG-SGA to the Dutch setting. METHODS: The PG-SGA was translated and culturally adapted, following the International Society for Pharmacoeconomics and Outcomes Research principles. Perceived content validity, comprehensibility, and difficulty were explored among a multidisciplinary sample of healthcare professionals and their cancer patients. Content validity, comprehensibility, and difficulty were operationalized by calculating item and scale indices. On scale level, indices of 0.80 to 0.90 were considered acceptable, and indices of 0.90 or greater were considered excellent. RESULTS: Consensus was reached on 91 and 8 differences in the forward and back translations, respectively. Scale Content Validity Index was 0.89. Scale Comprehensibility Index and Scale Difficulty Index of the patient-generated component of the PG-SGA were 0.99 and 0.96, respectively. Scale Comprehensibility Index and Scale Difficulty Index of the professional component were 0.81 and 0.55, respectively. CONCLUSIONS: Translation and cultural adaptation of the PG-SGA according to the International Society for Pharmacoeconomics and Outcomes Research principles resulted in a Dutch version that maintained the purpose, meaning, and format and have acceptable content validity. Now a Dutch version of the PG-SGA is available that is considered comprehensible and easy by patients, and comprehensible and relevant by professionals. However, the professional component was considered difficult by the PG-SGA-naive professionals, which indicates a need for training. IMPLICATIONS FOR PRACTICE: A similar systematic approach for future translations of the PG-SGA is recommended, to safeguard cultural equivalence.

RESUMO

PURPOSE OF REVIEW: The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is used internationally as the reference method for proactive risk assessment (screening), assessment, monitoring and triaging for interventions in patients with cancer. This review aims to explain the rationale behind and data supporting the PG-SGA, and to provide an overview of recent developments in the utilization of the PG-SGA and the PG-SGA Short Form. RECENT FINDINGS: The PG-SGA was designed in the context of a paradigm known as 'anabolic competence'. Uniquely, the PG-SGA evaluates the patient's status as a dynamic rather than static process. The PG-SGA has received new attention, particularly as a screening instrument for nutritional risk or deficit, identifying treatable impediments and guiding patients and professionals in triaging for interdisciplinary interventions. The international use of the PG-SGA indicates a critical need for high-quality and linguistically validated translations of the PG-SGA. SUMMARY: As a 4-in-1 instrument, the PG-SGA can streamline clinic work flow and improve the quality of interaction between the clinician and the patient. The availability of multiple high-quality language versions of the PG-SGA enables the inclusion of the PG-SGA in international multicenter studies, facilitating meta-analysis and benchmarking across countries.

RESUMO

OBJECTIVE: To identify malnutrition assessment methods in cancer patients and assess their content validity based on internationally accepted definitions for malnutrition. STUDY DESIGN AND SETTING: Systematic review of studies in cancer patients that operationalized malnutrition as a variable, published since 1998. Eleven key concepts, within the three domains reflected by the malnutrition definitions acknowledged by European Society for Clinical Nutrition and Metabolism (ESPEN) and the American Society for Parenteral and Enteral Nutrition (ASPEN): A: nutrient balance; B: changes in body shape, body area and body composition; and C: function, were used to classify content validity of methods to assess malnutrition. Content validity indices (M-CVIA-C) were calculated per assessment method. Acceptable content validity was defined as M-CVIA-C ≥ 0.80. RESULTS: Thirty-seven assessment methods were identified in the 160 included articles. Mini Nutritional Assessment (M-CVIA-C = 0.72), Scored Patient-Generated Subjective Global Assessment (M-CVIA-C = 0.61), and Subjective Global Assessment (M-CVIA-C = 0.53) scored highest M-CVIA-C. CONCLUSION: A large number of malnutrition assessment methods are used in cancer research. Content validity of these methods varies widely. None of these assessment methods has acceptable content validity, when compared against a construct based on ESPEN and ASPEN definitions of malnutrition.

RESUMO

INTRODUCTION: Two replicate randomized, placebo-controlled six-month trials (RCTs) and an open-label treatment extension (OLE) comprised the pegloticase development program in patients with gout refractory to conventional therapy. In the RCTs, approximately 40% of patients treated with the approved dose saw complete response (CR) of at least one tophus. Here we describe the temporal course of tophus resolution, total tophus burden in patients with multiple tophi, tophus size at baseline, and the relationship between tophus response and urate-lowering efficacy. METHODS: Baseline subcutaneous tophi were analyzed quantitatively using computer-assisted digital images in patients receiving pegloticase (8 mg biweekly or monthly) or placebo in the RCTs, and pegloticase in the OLE. Tophus response, a secondary endpoint in the trials, was evaluated two ways. Overall tophus CR was the proportion of patients achieving a best response of CR (without any new/enlarging tophi) and target tophus complete response (TT-CR) was the proportion of all tophi with CR. RESULTS: Among 212 patients randomized in the RCTs, 155 (73%) had ≥ 1 tophus and 547 visible tophi were recorded at baseline. Overall tophus CR was recorded in 45% of patients in the biweekly group (P = 0.002 versus placebo), 26% in the monthly group, and 8% in the placebo group after six months of RCT therapy. TT-CR rates at six months were 28%, 19%, and 2% of tophi, respectively. Patients meeting the primary endpoint of sustained urate-lowering response to therapy (responders) were more likely than nonresponders to have an overall tophus CR at six months (54% vs 20%, respectively and 8% with placebo). CONCLUSIONS: Pegloticase reduced tophus burden in patients with refractory tophaceous gout, especially those achieving sustained urate-lowering. Complete resolution of tophi occurred in some patients by 13 weeks and in others with longer-term therapy. TRIAL REGISTRATIONS: NCT00325195, NCT01356498.

RESUMO

BACKGROUND: Involuntary weight loss (IWL) is frequent in advanced cancer patients causing compromised anticancer treatment outcomes and function. Cancer cachexia is influenced by nutrition impact symptoms (NIS). The aim of this study was to explore the frequency of NIS in advanced patients and to assess specific interventions guided by a 12-item NIS checklist. METHODS: Consecutive patients from an outpatient nutrition-fatigue clinic completed the NIS checklist. The NIS checklist was developed based on literature review and multiprofessional clinical expert consensus. Chart review was performed to detect defined NIS typical interventions. Oncology outpatients not seen in the nutrition-fatigue clinic were matched for age, sex, and tumor to serve as controls. RESULTS: In 52 nutrition-fatigue clinic patients, a mixed cancer population [IWL in 2 months 5.96 % (mean)], the five most frequent NIS were taste and smell alterations 27 %, constipation 19 %, abdominal pain 14 %, dysphagia 12 %, and epigastric pain 10 %. A statistically significant difference for NIS typical interventions in patients with taste and smell alterations (p = 0.04), constipation (p = 0.01), pain (p = 0.0001), and fatigue (p = 0.0004) were found compared to the control population [mixed cancer, 3.53 % IWL in 2 months (mean)]. CONCLUSION: NIS are common in advanced cancer patients. The NIS checklist can guide therapeutic nutrition-targeted interventions. The awareness for NIS will likely evoke more research in assessment, impact, and treatment.
