Abstract
BACKGROUND Benchmarking regulatory systems of low- and middle-income countries with mature systems provides an opportunity to identify gaps, enhance review quality, and reduce registration timelines, thereby improving patients' access to medicines. The aim of this study was to compare the medicines registration process of the Medicines Control Authority of Zimbabwe (MCAZ) with the regulatory processes in Australia, Canada, Singapore, and Switzerland. METHODS A questionnaire that standardizes the review process, allowing key milestones, activities and practices of the five regulatory authorities was completed by a senior member of the divisions responsible for issuing marketing authorizations. RESULTS The MCAZ has far fewer resources than the regulatory authorities in the comparator countries, but employs three review models, which is in line with international best practice. The MCAZ registration process is similar to the comparator countries in key milestones monitored, but differs in the target timelines for these milestones. The MCAZ is comparable to the comparator authorities in implementing the majority of good review practices, although it significantly lags behind in transparency and communication. CONCLUSION This study identified the MCAZ strengths and opportunities for improvement, which if implemented, will enable the achievement of its vision to be a leading regulatory authority in Africa.

Current Regulatory Requirements for Biosimilars in Six Member Countries of BRICS-TM: Challenges and Opportunities. Front Med (Lausanne) 2021; 8:726660. [PMID: 34568384 PMCID: PMC8458962 DOI: 10.3389/fmed.2021.726660] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 08/11/2021] [Indexed: 11/21/2022] Open
Abstract
Background: The aim of the study was to identify, interpret, and compare the current perspectives of regulatory agencies in six member countries of BRICS-TM (Brazil, Russia, India, China, South Africa, Turkey, and Mexico) on the different criteria used for biosimilar development and marketing authorisation process. Methods: A semi-quantitative questionnaire was developed covering the organisation of agency, biosimilar development criteria and marketing authorisation process and sent to seven regulatory agencies covering the BRICS-TM countries. All data was kept anonymous and confidential. Data processing and analysis was carried out; descriptive statistics were used for quantitative data and content analysis was employed to generate themes for qualitative data. Results: Out of the seven regulatory agencies included in the study, six representatives provided the responses. The perspectives of these six regulatory agencies varied on a number of aspects relating to the review criteria for biosimilar development and licencing process. The most prevalent model for data assessment is the “full review” of a marketing authorisation application. There is lack of a standard approach across the agencies on sourcing of the reference biological product, in vivo toxicity studies and confirmatory clinical studies. Most agencies restrict interaction with biosimilar developers and any scientific advice is non-binding. The marketing authorisation approval depends on scientific assessment of the dossier, sample analysis and GMP certification. The agencies do not issue any public assessment report specifying the summary basis of biosimilar approval. Conclusion: Regulatory agencies across the six emerging economies are steadily improving the regulatory mechanism in the area of biosimilars. However, there remains scope for increasing the effectiveness and efficiency of the processes by encouraging open and transparent interaction with developers, adopting a flexible approach toward accepting advanced analytical data in lieu of clinical studies and enhancing regulatory reliance amongst agencies. This will help to simplify the new biosimilar development programmes and make them more cost-effective.

Evaluation of the Review Models and Approval Timelines of Countries Participating in the Southern African Development Community: Alignment and Strategies for Moving Forward. Front Med (Lausanne) 2021; 8:742200. [PMID: 34513894 PMCID: PMC8429484 DOI: 10.3389/fmed.2021.742200] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Accepted: 08/06/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction: Regulatory reliance, harmonization and work sharing have grown over the last few years, resulting in greater sharing of work and information among regulators, enabling efficient use of limited resources and preventing duplication of work. Various initiatives on the African continent include ZaZiBoNa, the Southern African Development Community (SADC) collaborative medicines registration initiative. ZaZiBoNa has resulted in great savings in time and resources; however, identified challenges include lack of clear information regarding the participating countries registration processes and requirements as well as lengthy registration times. The aim of this study, therefore, was to compare the data requirements and review models employed in the assessment of applications for registration, the target timelines for key milestones and the metrics of applications received and approved in 2019 and 2020 by Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. Methods: A senior member of the division responsible for issuing marketing authorisations completed an established and validated questionnaire, which standardizes the review process, allowing key milestones, activities and practices of the six regulatory authorities to be identified and compared. The completed questionnaires were validated by the heads of the respective agencies. Results: The majority of applications received and approved by all six agencies in 2019 and 2020 were for generics. The mean approval times for generics varied across the countries, with ranges of 218-890 calendar days in 2019 and 158-696 calendar days in 2020. All three types of scientific assessment review models were used by the six agencies and data requirements and extent of scientific assessment were similar for five countries, while one conducted full reviews for new active substances. A large variation was observed in the targets set by the six agencies for the different milestones as well as overall approval times. Conclusions: The study identified the strengths of the countries as well as opportunities for improvement and alignment. Implementation of the recommendations made as in this study will enhance the countries' individual systems, enabling them to efficiently support the ZaZiBoNa initiative.

Abstract
Introduction: National medicines regulatory agencies are faced with challenges including limited resources and technical capacity, resulting in countries collaborating and sharing resources to improve efficiency of the review process to facilitate access to quality-assured medicines by their populations. One such collaboration is the Southern African Development Community (SADC) medicines registration collaborative initiative, ZaZiBoNa. Countries participate in the initiative by contributing to regulatory reviews and good manufacturing practices inspections. The aim of this study was to review and compare the registration processes of regulatory authorities of Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe to identify strategies for better alignment. Methods: A senior member of the division responsible for issuing marketing authorisations completed an established and validated questionnaire, which standardises the review process, allowing key milestones, activities and practices of the six regulatory authorities to be identified and compared. The completed questionnaires were validated by the heads of the respective agencies. Results: The six countries vary in population and in the size of their respective regulatory agency and the resources allocated to regulatory reviews. The review processes of the six agencies were similar; however, differences were noted in the milestones recorded; for example, two of the countries did not record the start of the scientific assessment. Additionally, decisions for marketing authorisation were made by an expert committee in four of the countries and by the head of the agency and the Minister of Health in two countries. All six agencies implemented the majority of good review practices; however, the need for improvement in the areas of transparency and communication and quality decision making practices was a common finding for all six countries. Conclusions: Participation in the ZaZiBoNa initiative has improved the way in which the six agencies perform regulatory reviews in their countries, highlighting the realisation of one of the key objectives of the initiative, which was building the expert capacity of member countries. Other agencies in the SADC region and beyond can use the results of this study to identify best practices, which in turn, could improve their regulatory performance.

Abstract
Objectives: The aim of this study was to identify, compare and evaluate regulatory requirements for the biosimilar development and review processes in BRICS-TM (Brazil, Russia, India, China, South Africa, Turkey, Mexico) countries with mature regulatory systems of Australia, Canada, Singapore and Switzerland. It is hoped that this benchmark study provides an opportunity for BRICS-TM agencies to identify the key areas for improvement in their regulatory processes. Materials and Methods: A semi-quantitative questionnaire was developed covering the different criteria used in biosimilar development and registration process. Eleven regulatory agencies from BRICS-TM and ACSS (Australia, Canada, Switzerland and Singapore) countries were invited to take part in this study. Data processing and analysis was carried out using descriptive statistics for quantitative data and content analysis to generate themes for qualitative data. Results and Discussions: Nine of the 11 regulatory agencies recruited for the study completed the questionnaire. China and Singapore did not meet the deadline due to lack of resources. The organisational structure of BRICS-TM agencies revealed support from external assessors by most of these agencies in comparison with ACSS agencies. There was absence of reliance approach and participation in harmonisation activities across most BRICS-TM agencies. Despite alignment over biosimilarity, the mandate for in vivo non-clinical studies and additional local clinical studies in some of the BRICS-TM countries illustrates a lack of effective implementation of a step-wise approach. Adopting flexible regulatory standards in the sourcing of a RBP (Reference Biologic Product) by BRICS-TM similar to ACSS, will facilitate cost-effective development of biosimilar products. Conclusions: Comparative assessment of the biosimilar regulatory framework of BRICS-TM with ACSS agencies reveals the scope for enhancing efficiency of the regulatory approval process. To achieve this, BRICS-TM agencies should consider relying on reference agencies for alternative review mechanisms such as abridged or verification models, streamlined processes for providing scientific advice to developers and for waiving local clinical studies in-lieu of advanced scientific data.

Abstract
Background: The aims of this study were to compare the overall regulatory review timelines achieved by the South African Health Products Regulatory Authority (SAHPRA) in 2020 to the timelines historically achieved by the Medicines Control Council (MCC). This study also aimed to evaluate the regulatory review processes and the good review practices that have been implemented by SAHPRA to support the assessment of new chemical entities and generic product applications for market authorization in the business-as-usual and backlog process streams. Methods: A questionnaire was completed and verified by SAHPRA to describe the structure of the organization, the resources available, the process for regulatory review of new chemical entities and generic products and the level of implementation of good review practices and regulatory decision-making practices for market authorization. Data were collected and analyzed on the overall approval timelines for new chemical entities and generic products registered by SAHPRA in 2020 in the business-as-usual and backlog process streams. Results: A full, independent scientific review was conducted for all new chemical entities and generic product applications in the business-as-usual stream. Facilitated regulatory pathways were introduced for the review of new chemical entities and generic products in the backlog stream. As a result, the timelines for approval of applications in the backlog stream were 68% quicker for both new chemical entities and generics, using facilitated regulatory pathways, such as abridged and verification review models. Conclusion: The comparisons made through this study provided insight into the improvements that have been made through the establishment of SAHPRA and the transition in 2018 from the MCC. The re-engineered processes that have been developed and implemented by SAHPRA to address the backlog in the review of the applications for market authorization have demonstrated a decrease in the overall median approval times. The expansion of these processes into the routine review of medical products will contribute to the enhanced regulatory performance of SAHPRA and patients’ access to new medicines.

Abstract
BACKGROUND Biosimilars are expected to emerge as a rapidly growing segment of the biopharmaceutical industry. However, the biosimilar industry faces multiple challenges and obstacles in developing and marketing these complex products. Divergent regulatory framework in emerging countries adds to repetitive trials and increased cost of biosimilar development, delaying the approval process. Due to such roadblocks, healthcare systems and patients are yet to realize the full benefits of biosimilars. OBJECTIVES The aim of this exploratory study was to specifically identify the challenges faced by the industry in emerging countries including Brazil, Russia, India, China, South Africa, Turkey and Mexico (BRICS-TM), pertaining to biosimilar development and the regulatory approval process. In particular, this study aims to understand the perceptions of industry on the barriers faced by them in terms of complexity, costs for biosimilar development and time-to-market for biosimilar product. METHODS A semi-quantitative questionnaire was designed based on secondary research. A total of 93 industry personnel and representatives from 14 trade associations from the BRICS-TM countries with 15-year minimum experience were identified and invited to take part in the study and participate in interviews, which were recorded verbatim. Data processing and analysis was carried out; descriptive statistics were used for quantitative data and content analysis was employed to generate themes for qualitative data. RESULTS Of the 107 biopharmaceutical industry and trade association representatives invited to participate in the study, respondents from 33 biopharmaceutical companies agreed to take part and underwent the interviews. The industry personnel perceived biosimilar guidelines and approval processes as being protracted and in a state of evolution. The absence of an abridged approval pathway limited effectiveness of the regulatory process. The biggest hurdles in the development of biosimilar dossiers were the sourcing of the reference biological product and expectations around confirmatory clinical trials by the agencies. The non-comprehensive implementation of a stepwise approach resulting in unnecessary toxicity studies was also reported as a major challenge. The authors recommend further primary research with BRICS-TM regulatory agencies in order to propose a simplified pathway for development and approval. CONCLUSIONS Lack of standardized biosimilar development criteria and regulatory convergence across BRICS-TM agencies has led to challenges in multi-country development programmes for these medicines, in turn impacting the ability of industry to launch newer and more affordable biosimilars.

Standardizing fatigue measurement in multiple sclerosis: the validity, responsiveness and score interpretation of the PROMIS SF v1.0 - Fatigue (MS) 8a. Mult Scler Relat Disord 2021; 54:103117. [PMID: 34256350 DOI: 10.1016/j.msard.2021.103117] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 06/21/2021] [Accepted: 06/24/2021] [Indexed: 01/16/2023]
Abstract
BACKGROUND Fatigue is one of the most common and the single most disabling symptom of multiple sclerosis (MS). However, there is a lack of consensus on the most appropriate fatigue measures in clinical practice and research, based upon rigorously validated, generalizable, and publicly available instruments. The objective of this research was to generate additional evidence regarding the validity and applicability of the PROMIS SF v1.0 - Fatigue (MS) 8a, including content validity, reliability, construct validity and responsiveness, as well as to assess minimal important difference (MID) estimates and a score interpretation tool to aide meaningful individual level score interpretation. METHODS A mixed-methods, sequential design was followed. Cognitive debriefing (CD) interviews (n=29) were performed with MS patients, to assess the relevance and comprehensiveness of the PROMIS Fatigue (MS) 8a scores. To evaluate the psychometric properties of the PROMIS Fatigue (MS) 8a, two observational studies were conducted: a cross-sectional study at two US MS centers (n=296), and a 96-week longitudinal study in a UK MS Register cohort (n=384). Main outcomes and measures were estimates of known-groups validity, convergence validity, reliability, and responsiveness, a guide for interpreting PROMIS Fatigue (MS) 8a T-scores, and anchor-based MID estimates. RESULTS The CD interviews confirmed the comprehensiveness and relevance of the PROMIS Fatigue (MS) 8a in assessing MS fatigue. Cronbach's alpha (>0.9) and intra-class correlation coefficient (≥0.9) for test-retest scores at 5-7 days follow-up, supported strong internal consistency and test-retest reliability. Hypothesized differences were found across patient groups in patient reported fatigue and related concepts (analysis of variance [ANOVA], P <0.001). PROMIS Fatigue (MS) 8a scores were sensitive to bi-directional changes in fatigue (GHS fatigue global question) and physical health (PROMIS GHS GPH), over a 52-week follow-up. Score changes of 3.4-4 points are proposed as MID criteria for minimal improvement or worsening in fatigue. CONCLUSION This research extends the evidence supporting the content validity and the robust psychometric performance of the PROMIS Fatigue (MS) 8a across US and UK MS populations. Importantly, data supporting the measure's integration in clinical practice and research, including meaningful score interpretation, are now available.

Abstract
e18615 Background: It is recommended to include patient-reported outcomes (PROs) in cancer trials to ensure clinical benefit based on patients’ perceptions. For multiple myeloma patients, PRO measurement is essential to understand the impact of treatment on their physical and psychosocial functional behaviour. However, it is unclear which PRO instruments are utilized in multiple myeloma trials, how often they are used and whether results are consistently reported. The aim of this project was to explore the use and frequency of PRO instruments in randomized controlled trials for multiple myeloma and to assess the consistency of their reporting. Methods: Within the European Hematology Association (EHA) project to develop guidelines for the use of PROs in adult patients with hematological malignancies, MEDLINE and CENTRAL were systematically searched for randomized controlled trials investigating multiple myeloma between 2015 and 2020. Study design, disease and treatment characteristics, the primary outcome and used PRO instrument(s) were extracted using a pre-defined template. To assess the consistency of PRO reporting, study registries were compared with publications, study protocol and Health Technology Assessment (HTA) reports where available. Results: Overall, 10,707 records were found. Following screening for randomized-controlled trials, 283 ongoing, completed or published studies were included for review. 118 studies planned the use of PROs. The most frequently used PRO instrument (92 studies) was the EORTC QLQ-30, an instrument that measures health-related quality-of-life (HRQoL) in cancer patients. The disease-specific questionnaire EORTC-MY20 was also frequently used (50 studies). Likewise, the HRQoL instrument EQ-5D was used in 50 studies. Overall, 38 different PRO instruments were reported. In 39 studies for which a study protocol was found, only 19 reported PRO instruments consistently with the trial registry for the study. In addition, in 30 studies, for which a publication reported PRO results (58 overall), the information on PRO instruments differed between publication and the trial registry. For example, PRO instruments mentioned in the registry were omitted in the respective publications. Additionally, information on PRO in HTA reports was available for 26 studies, of which 18 reports were consistent with the trial registries. Conclusions: The results show that measurement of PROs still remain under-utilized in multiple myeloma research. While most PRO instruments identified in this review comply with the recommendations for incorporating PROs into clinical research in adult oncology, they are often inconsistently reported. Thus, reporting standards for the use of PROs are needed to ensure consistency in the use and reporting of PROs.

Abstract
Purpose The aims of this study were to assess the current regulatory review process of the Medicines Control Authority of Zimbabwe (MCAZ), identify key milestones and target timelines, evaluate the overall performance from 2017 to 2019, identify good review practices, evaluate the quality of decision-making processes, and identify the challenges and opportunities for improvement. Methods A questionnaire was completed by the MCAZ. The agency has participated in the Optimising Efficiencies in Regulatory Agencies (OpERA) program, a multinational endeavor to characterize assessment procedures and metrics associated with regulatory agencies and regional regulatory initiatives. Data identifying the milestones and overall approval times for all products registered MCAZ from 2017 to 2019 were collected and analyzed. Results The MCAZ conducts a full review of quality, safety, and efficacy data for generics and biosimilars not approved by a reference agency, an abridged review for products approved by a reference agency and a verification review for World Health Organization prequalified products under the collaborative registration procedure. The highest number of reviewed products is generics manufactured by foreign companies. There has been an improvement in review times for all categories of products over the three-year period. Guidelines, standard operating procedures, and review templates are in place and the majority of indicators for good review practices are implemented. Although quality decision-making practices are implemented, there is no formal framework in place. Conclusion The MCAZ successfully implements three types of review models in line with international standards. Overall, target timelines are realistic and what is achievable with the current available resources. Recommendations made such as the review of available human resources, separation of agency and company time when setting and measuring targets, review of the templates and benefit-risk framework used for abridged review, and development of a decision-making framework present opportunities for an enhanced regulatory review process.

Abstract
Background: National regulatory agencies of various sizes and maturity levels, including the South African Health Products Regulatory Authority (SAHPRA), have had to revise systems and re-engineer processes in order to adapt to the new regulatory environment and increase the effectiveness of regulatory operations. This study aimed to develop a new regulatory review model for improved regulatory performance, underpinned by the parameters of the World Health Organization Global Benchmarking Tool (WHO GBT) that support strengthening of regulatory systems.
Methods: A new enhanced model for regulatory review, was developed based on the key recommendations from 6 studies, previously conducted by the authors, that were identified as fundamental elements in enhancing regulatory performance. The elements selected to define the new regulatory review model were endorsed through the integration of the parameters of the WHO GBT that, when embedded within regulatory systems, support enhanced regulatory performance.
Results: Opportunities for improvement in regulatory performance were identified and include quality measures; monitoring and evaluating review times; a risk-based evaluation; transparency and communication; and training and education. An improved model for the South African regulatory review and benefit-risk (BR) assessment supported by quality decision-making was proposed as well as recommendations for the application of risk-stratification strategies, strengthening of reliance networks, reinforcing good regulatory practices (GRPs) and enhancing transparency. Conclusion: If implemented the proposed improved regulatory model may pave the way towards more efficient and transparent, streamlined review processes, coupled with increased consistency, evidence-based decision-making practices, reduced timelines and improved patients’ access to new medicines in South Africa.

Reliability of a Novel Hematological Malignancy Specific Patient-Reported Outcome Measure: HM-PRO. Front Pharmacol 2020; 11:571066. [PMID: 33192513 PMCID: PMC7606444 DOI: 10.3389/fphar.2020.571066] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 08/25/2020] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Patients' experience of symptoms often goes undetected during consultation in an outpatient clinic, and the use of a patient-reported outcome measure (PRO) in such a setting could be useful to aid treatment decision-making. A new PRO measure, the HM-PRO (Hematological Malignancy Specific Patient-Reported Outcome Measure) has been recently developed to evaluate hematological malignancy (HM) patients' health-related quality of life (HRQoL) and their symptom experience in daily clinical practice as well as in research. The objectives of the study were to assess: the internal consistency of the scores for Part A (impact) and its four domains (physical behavior; social well-being; emotional behavior; and eating and drinking habits) and Part B (signs and symptoms); and the test-retest reliability of the individual items of the newly developed hematological malignancy specific composite measure, the HM-PRO. METHODS This was a prospective longitudinal observational study where 150 patients with different HMs and different stage of disease (male n = 98 (65.3%); mean age 64.9 ± 14.4 years, range 17.9-89.2 years; mean time since diagnosis 3.7 ± 4.9 years, range 0.04-25.8 years) completed the HM-PRO at baseline (assessment 1 at t1) and after 7 days (assessment 2 at t2). Data analysis was performed using IBMSPSS 23 statistical software. RESULTS The Cronbach's alpha estimates of the HM-PRO for both assessment points (t1 and t2) were above 0.9 for Part A, and above 0.8 for Part B, showing strong stability of the measurement. The level of agreement for the reproducibility between the two assessments, using intra-class correlation coefficients (ICC), was very strong with Part A: ICC = 0.93 (95% CI = 0.90-0.95), and Part B: ICC = 0.91 (0.88-0.93). The ICC for the four domains of Part A ranged from 0.85-0.91. The ICC was greater than 0.8 for overall score of Part A and Part B for all the 10 diagnoses, confirming strong reliability. CONCLUSION This study clearly indicates that the HM-PRO possesses strong test-retest reliability for both Part A and Part B. The Cronbach's alpha confirmed acceptable internal consistency. The extensive reliability testing described in this study supports the generic nature of the HM-PRO for use in hematological malignancies in both routine clinical practice, to aid treatment decisions, as well as in research.

Quality-of-life issues and symptoms reported by patients living with haematological malignancy: a qualitative study. Ther Adv Hematol 2020; 11:2040620720955002. [PMID: 33101618 PMCID: PMC7549153 DOI: 10.1177/2040620720955002] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 07/31/2020] [Indexed: 11/16/2022] Open
Abstract
Background Our aim was to identify health-related quality-of-life (HRQoL) issues and symptoms in patients with haematological malignancies (HMs) and develop a conceptual framework to reflect the inter-relation between them. Methods A total of 129 patients with HMs were interviewed in a UK multicentre qualitative study. All interviews were audio recorded, transcribed and analysed using NVivo-11. Results Overall, 34 issues were reported by patients and were grouped into two parts: quality of life (QoL) and symptoms. The most prevalent HRQoL issues were: eating and drinking habits; social life; physical activity; sleep; and psychological well-being. Furthermore, most prevalent disease-related symptoms were: tiredness; feeling unwell; breathlessness; lack of energy; and back pain. The most prevalent treatment side effects were: tiredness; feeling sick; disturbance in sense of taste; and breathlessness. Conclusions Both HMs and their treatments have a significant impact on patients' HRQoL, in particular on issues such as job-role change, body image and impact on finances.

Hematological Malignancy Specific Patient-Reported Outcome Measure (HM-PRO): Construct Validity Study. Front Pharmacol 2020; 11:1308. [PMID: 33013368 PMCID: PMC7506039 DOI: 10.3389/fphar.2020.01308] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 08/07/2020] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Validity is the ability of an instrument to measure what it claims to measure. It means the degree to which the empirical evidence supports the trustworthiness of interpretations based on the calculated scores. The hematological malignancy (HM) specific patient reported outcome measure (HM-PRO), is a newly developed instrument for use in daily clinical practice as well as in research. This study, provides the evidence for construct validity of the HM-PRO, specifically focusing on the convergent and divergent validity compared to the other established instruments used in hematology. METHODS This validation study adopted a prospective cross-sectional design where a heterogeneous group of patients diagnosed with different HMs and different disease state were recruited. A total of 905 patients were recruited from seven secondary care hospitals in the UK and online through five patient organizations. Patients were asked to complete the HM-PRO and other cancer specific PRO's, FACT-G and EORTC QLQ C-30. Data analysis was performed using IBM SPSS 23 statistical software. RESULTS A total of 486 males (53.7%) and 419 females (46.3%), with a mean age of 64.3 (± 12.4) years and mean time since diagnosis of 4.6 ( ± 5.2) were recruited. The total score of Part A of the HM-PRO highly correlated with the five functional scales of the EORTC QLQ-C30 (Physical = -0.71, Role = -0.72, Emotional = -0.64, Cognitive = -0.58, Social = -0.74-p < 0.001). With respect to correlation with FACT-G, the total score of Part A of the HM-PRO highly correlated with Physical (-0.74), Emotional (-0.57), Functional (-0.66) domains and overall score of FACT-G (-0.74). Similarly, the total score of Part B of the HM-PRO highly correlated with three symptoms scales of EORTC QLQ-C30 (Fatigue scale = -0.74, Nausea and Vomiting = -0.52, Pain = -0.59-p < 0.001) and individual symptom items (Dyspnea = 0.51, Insomnia= 0.43, Appetite loss = 0.54-p < 0.001). CONCLUSION The construct validity evidence presented in this research is a testimony to the HM-PRO's ability to measure HRQoL issues which it intends to measure. This is of utmost importance when a PRO is used in routine clinical practice so that the interpretation of the scores or response to an individual item is understood by the clinicians/nurses as intended by the patients.

Abstract
INTRODUCTION The aim of this study was to explore patients' knowledge and perspectives in Istanbul, Turkey about the pharmaceutical regulatory review and reimbursement processes with respect to patients' access to new medicines. METHODS For the purpose of this study a tailored made paper-based questionnaire, Patient Perspective Questionnaire (PPQ), was developed and subsequently piloted in the target population. A total of 350 patients were recruited consecutively into the study from hospital outpatient clinics, general practice, community pharmacies, patient organisations in 28 different districts of Istanbul receiving treatment for chronic conditions. In addition, 22 patients were randomly selected from the cohort for face-to-face interviews in order to obtain further insights about the relevance of the PPQ, and to help with formalising a set of recommendations for the involvement of patients in both processes. Data processing and analyses were carried out using SPSS version 23 statistical software. RESULTS Overall 210 (60% response rate) completed the PPQ (51% males) with the mean age of 56, median of 54 and range of 18-75. Most patients in this study (84%) seemed to know that medicines had to be approved by the government. However, 81% of patients were not aware of the regulatory review process with 73% being unaware of approval timelines. Furthermore, 78 (37%) patients described the Turkish approval process to be of a lower standard compared to that of the US and EU. However, 147 (70%) of patients believed that there are novel alternative medicines for their disease available in other developed countries. Similarly, 126 (60%) patients thought that new medicines only become available in Turkey after their availability in the other developed countries. In contrast, patients in this cohort were more aware of the reimbursement system in Turkey where the majority expressed their satisfaction and 34% described access to new medicines to be adequate. In addition, the majority of patients (75%) recognised that the government is the main payer, even though insufficient information is provided about new medicines. Patients stated that they do not have any role in the decision-making process for the approval or reimbursement of new medicines and therefore most of them indicated that they wish to be more involved in reimbursement (60%) as well as in the approval process (58%). DISCUSSION Faster access to medicines, improved health and pharmaceutical care as well as lower prices were considered by the study patients as the improvement priorities. Further, they were able to offer academic collaboration and active patient involvement in both processes as possible solutions.

Int J Health Policy Manag 2020; 11:128-137. [PMID: 32610811 PMCID: PMC9278608 DOI: 10.34172/ijhpm.2020.86] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Accepted: 05/30/2020] [Indexed: 11/09/2022] Open
Abstract
Background: The development of a medicine is not only underpinned by good science but also by Quality DecisionMaking Practices (QDMPs). Indeed, it is important to ensure that all organisations involved in the lifecycle of medicines are aligning their practices in decision-making to the QDMPs to ensure quality, transparent and consistent decisionmaking processes. Methods: The aim of this study was to evaluate the practicality of QoDoS (Quality of Decision-Making Orientation Scheme) in assessing the incorporation of ten QDMPs during the development, review and reimbursement of medicines, illustrated by case studies with a pharmaceutical company, a regulatory authority and a health technology assessment (HTA) agency. Individuals from each organisation completed the 47-item QoDoS questionnaire. Results: The results demonstrate the applicability of QoDoS in identifying favourable and unfavourable practices and in assessing the consistency and transparency of the QDMPs within each organisation, as well as across the different stakeholders. Furthermore, the study established the value of the methodology in raising awareness of the biases and best practices in decision-making, as well as having a basis for discussion for differences within and across stakeholders to promote consistency and alignment in decision-making. Finally, the QoDoS demonstrated the need for improvement across a number of decision-making practices for the 3 organisations such as the evaluation of alternatives and of the decision impact. Conclusion: The QoDoS can be used to benchmark organisations’ decision-making practices to provide a basis for discussion to ultimately encourage a level of trust across and within organisations and helping to identify areas for improvement.

Abstract
Background National regulatory authorities (NRAs) make the decision to register a medicine based on an assessment of its benefits and risks and publicly available assessment reports are used as a tool to communicate the basis for the decision. The Universal Methodology for Benefit-Risk Assessment (UMBRA) has also been used to effectively communicate the basis of regulatory decisions. Many NRAs in emerging markets place reliance on the public assessment reports (PARs) of reference agencies to inform about their own regulatory decisions. However, PAR users often criticise the redacted nature of PARs and may be challenged in identifying key benefits and risks, value judgements, and benefit-risk (BR) trade-offs. Methods PARs for ertugliflozin l-pyroglutamic acid, erenumab, and durvalumab published by regulatory bodies in Australia, Europe, Canada, and the United States were compared with the validated UMBRA Benefit-Risk Template to evaluate the BR decision documentation. Published validation of UMBRA included report of a consortium of four regulatory authorities in Australia, Canada, Switzerland, and Singapore indicating that their clinical assessment templates were modified to align with the UMBRA approach. A focus group discussed the use of PARs as potential knowledge management tools for stakeholder understanding of regulatory decision making. The South African Health Product Regulatory Authority (SAHPRA) approach to document and communicate the BR decisions was evaluated. Results Results indicate key elements to include in the PARs including regulatory history, an effects table and a record of the strengths and uncertainties for each benefit and risk. Focus group participants agreed that a harmonised PAR template would support improved regulatory decision-making transparency. SAHPRA communication of BR decisions could be improved through the use of the UMBRA BR Template as a guidance for BR assessment and the basis of the South Africa public assessment report format. Conclusion SAHPRA's use of a structured template that supports transparent and quality decision making could have a major impact in ensuring consistency in the BR assessment of new medicines. The implementation of this effective approach for communicating BR decisions will advance agency goals of being a trusted, responsive, accountable regulatory body in which all healthcare stakeholders may rely on with confidence.

Abstract
BACKGROUND The Hyperhidrosis Quality of Life Index (HidroQoL©) is a validated patient-reported outcome measure capturing the quality of life of people affected by hyperhidrosis. OBJECTIVES We aimed to extend the validity evidence to physician-confirmed diagnosis of primary axillary hyperhidrosis. METHODS Data from a phase III randomized placebo-controlled clinical trial were used (n = 171). Confirmatory factor analysis was carried out to confirm the a priori two-factor structure of the HidroQoL. Internal consistency was assessed using Cronbach's α. Intraclass correlation coefficients (ICCs) were calculated to evaluate test-retest reliability after days -7 to -4. Convergent validity was assessed using correlations with the Dermatology Life Quality Index (DLQI), the Hyperhidrosis Disease Severity Scale (HDSS) and gravimetric sweat production. Known groups were analysed to evaluate discriminative validity. Responsiveness after 29 days was assessed and minimal important difference (MID) values were calculated using both anchor- and distribution-based approaches. All analyses were carried out for total HidroQoL and its two domains. RESULTS The two-factor structure of the HidroQoL was confirmed. Internal consistency and test-retest reliability were strong (Cronbach's α 0·81-0·90; ICCs 0·89-0·93). Correlations with other outcome measures were in line with a priori hypotheses. The HidroQoL discriminated between different severity groups (P ≤ 0·001) and showed sensitivity to change towards improvement (P < 0·001). An MID value of 4 is proposed for the total scale. CONCLUSIONS This study supports excellent measurement properties including clinical applicability of the HidroQoL in primary axillary hyperhidrosis and suggests a MID of 4 be applied to clinical trial data.

Abstract
BACKGROUND The quality of life of patients at all stages of hematological malignancy is greatly affected by the disease and its treatment. There is a wide range of health-related quality of life (HRQoL) issues important to these patients. Any new instrument developed to measure HRQoL of such patients should be content valid, i.e., the items should be comprehensively relevant to the patients and their health condition. The aim of the present study was to examine content validity of a hematological malignancy specific patient reported outcome measure (HM-PRO) developed for use in routine clinical practice. METHODS Following literature review and semi-structured interviews, the generated themes and sub-themes were discussed to develop the prototype version of the HM-PRO. A 4-step approach was used for content validation: initial testing and cognitive interviewing; item rating; content validity panel meeting; final field testing and cognitive interviewing. Additional questions related to patients' perception of recall period and preferred sentence structure (i.e., question or statement) of the items were also asked during cognitive interviews. RESULTS The content analysis of 129 transcribed semi-structured interviews resulted in the prototype version of the instrument consisting of 58 items grouped into two parts: Part A (impact/HRQoL - 34 items) and Part B (signs and symptoms - 24 items). The initial testing showed intra-class correlation coefficient (ICC) of >0.8 for both Part A and Part B. Item rating for language clarity, completeness, relevance, and response scale by experts and patients showed content validity index for scales average >0.8 for both Part A and Part B, except 0.64 for relevance for Part A by the patient panel. The final testing of the revised version of the instrument showed the Cronbach's alpha value of 0.91 for Part A and 0.76 for Part B, suggesting high internal consistency, and ICC of 0.91 for Part A and 0.76 for Part B. The recall period of "today" for Part-A and "last 3 days" for Part-B were the patients' preferred "recall period." Furthermore, the patients expressed preference to the HM-PRO items as statements. CONCLUSION The findings of this study confirm that the HM-PRO possesses a strong content validity, includes all the issues important to patients and is easy to read, understand and respond to spontaneously.

Abstract
The link between acne and psychiatric morbidities has been demonstrated in many studies; however, large scale studies aiming to reveal the psychosocial impact of acne are rare. The aim of this study was to assess the psychological burden of adult acne patients. This analysis was based on a multicenter study including 213 acne patients and 213 controls from 13 European countries. The Hospital Anxiety and Depression Scale (HADS), Dermatology Life Quality Index, and EuroQol 5 dimensions 3 levels scores of the patients with acne were analyzed. Patients with acne (n = 213) had higher HADS scores for anxiety (mean ± standard deviation 6.70 ± 3.84) and depression (3.91 ± 3.43) than the controls (p < 0.001 for both). For patients with acne, 40.6% reported that they were very concerned about their skin disease, 12.3% had suicidal ideation, and, among those, 10 (4%) patients implied that acne was the cause of their suicidal thoughts. After adjusting for other variables, patients who had suicidal ideation (p = 0.007, and adjusted odds ratio 3.32 [95% confidence interval (CI): 1.39-7.93]) and stressful life events (p < 0.001, and adjusted OR 5.85 [95% CI: 2.65-12.86]) had a greater chance of fulfilling the HADS criteria for anxiety. This study highlights the need for a psychotherapeutic approach in order to recognize the concerns of acne patients and optimize their treatment.

Abstract
Introduction Currently recommended patient‐reported outcome (PRO) measures for patients with pyruvate kinase (PK) deficiency are non‐disease‐specific. The PK Deficiency Diary (PKDD) and PK Deficiency Impact Assessment (PKDIA) were developed to be more targeted measures for capturing the symptoms and impacts of interest to this patient population. Methods The instruments were developed based on concept elicitation interviews with 21 adults and modified based on 20 cognitive interviews. The domain structure and item concepts of the PKDD and PKDIA were compared with currently recommended measures, the EORTC QLQ‐C30 and the SF‐36v2®. Results The PKDD is a seven‐item measure of the core signs and symptoms of PK deficiency. The PKDIA is a 14‐item measure of the impacts of PK deficiency on patients’ health‐related quality of life (HRQoL). Minimal similarities were found between the new measures and the EORTC QLQ‐C30 (eg, 43% of concepts were similar to the PKDD; 42% were similar to the PKDIA) and SF‐36v2® (57% of concepts were similar to the PKDD; 17% were similar to the PKDIA). Conclusions The PKDD and PKDIA fill a gap in the existing outcomes measurement strategy for PK deficiency. Future work includes psychometric evaluation of these newly developed measures.
