RESUMO

Interest in patient-centric initiatives to engage patients as partners in clinical research and inform drug development strategy, planning and execution has increased exponentially during the past decade. Adoption, use, organizational approach and infrastructure supporting patient-centric initiatives, however, varies widely from company to company. The Drug Information Association (DIA) in collaboration with the Tufts Center for the Study of Drug Development (Tufts CSDD) at the Tufts University School of Medicine developed and validated an assessment tool that companies can use to evaluate their organization's patient engagement preparedness and capabilities within the context of industry-wide practices. This paper discusses the development of the tool, the assessment experience, and implications for further refinement of the assessment process. Specifically, the team conducted an extensive literature review, compiled and analyzed case studies and gathered input from a working group of 18 biopharmaceutical companies. To validate the assessment tool and demonstrate its feasibility, the DIA-CSDD Tufts team conducted a pilot implementation involving onsite and virtual in-depth interviews among 14 biopharmaceutical companies. A subsequent paper will report on the findings from the 14 companies assessed.

RESUMO

BACKGROUND/OBJECTIVES: A few preliminary studies have documented the safety and feasibility of repeated short-term fasting in patients undergoing chemotherapy. However, there is a lack of data from larger randomized trials on the effects of short-term fasting on quality of life, reduction of side effects during chemotherapy, and a possible reduction of tumor progression. Moreover, no data is available on the effectiveness of fasting approaches compared to so-called healthy diets. We aim to investigate whether the potentially beneficial effects of short-term fasting can be confirmed in a larger randomized trial and can compare favorably to a plant-based wholefood diet. METHODS: This is a multicenter, randomized, controlled, two-armed interventional study with a parallel group assignment. One hundred fifty patients, including 120 breast cancer patients and 30 patients with ovarian cancer, are to be randomized to one of two nutritional interventions accompanying chemotherapy: (1) repeated short-term fasting with a maximum energy supply of 350-400 kcal on fasting days or (2) repeated short-term normocaloric plant-based diet with restriction of refined carbohydrates. The primary outcome is disease-related quality of life, as assessed by the functional assessment of the chronic illness therapy measurement system. Secondary outcomes include changes in the Hospital Anxiety and Depression Score and as well as frequency and severity of chemotherapy-induced side effects based on the Common Terminology Criteria of Adverse Events. Explorative analysis in a subpopulation will compare histological complete remissions in patients with neoadjuvant treatments. DISCUSSION/PLANNED OUTCOMES: Preclinical data and a small number of clinical studies suggest that repeated short-term fasting may reduce the side effects of chemotherapy, enhance quality of life, and eventually slow down tumor progression. Experimental research suggests that the effects of fasting may partly be caused by the restriction of animal protein and refined carbohydrates. This study is the first confirmatory, randomized controlled, clinical study, comparing the effects of short-term fasting to a short-term, plant-based, low-sugar diet during chemotherapy on quality of life and histological tumor remission. TRIAL REGISTRATION: ClinicalTrials.gov NCT03162289 . Registered on 22 May 2017.

RESUMO

BACKGROUND: Recently, drug development companies have sought out patient feedback to improve overall drug development. However, characterization of the overall impact and return on engaging with patients have not been determined. METHODS: The Drug Information Association (DIA), the Tufts Center for the Study of Drug Development (Tufts CSDD), and 17 other stakeholder organizations collaborated on a study to (1) quantify and define patient-centric initiatives (PCIs) utilized in clinical research and development and (2) to define evidence-based metrics and performance indicators that demonstrate return on engagement (ROE) of specific PCIs. We conducted a literature review, industry surveys, and in-depth interviews to determine and measure the impact of adopted PCIs. RESULTS: We identified and defined 30 PCIs used to engage with patients. We analyzed 121 case studies and created a comprehensive list of metrics assessing overall return to the organization and to patients. Advocacy Group Support and Involvement, Conducting Patient Advisory Panels, and Focus Groups were examples of PCIs with the lowest cost and largest impact with respect to quality, speed, and impact on the patient relative to other PCIs. CONCLUSION: The results from the literature review and use cases provide drug development teams with evidence and insights to help facilitate the adoption of specific PCIs within their organization and to help select those initiatives that would provide the highest impact to patients and development organizations. It is also hoped that the biopharmaceutical industry will apply the standardized metrics in the toolkit to systematically assess the overall return on engagement.

RESUMO

Olivine-hosted melt inclusions are commonly used to determine pre-eruptive storage conditions. However, this approach relies on the assumption that co-erupted olivines have a simple association with their carrier melts. We show that primitive olivine crystal cargoes and their melt inclusions display a high degree of geochemical disequilibrium with their carrier melts at Kilauea Volcano, Hawai'i. Within a given eruption, melt inclusions trapped in primitive olivine crystals exhibit compositional diversity exceeding that in erupted lava compositions since 1790 CE. This demonstrates that erupting liquids scavenge crystal cargoes from mush piles accumulating diverse melt inclusion populations over timescales of centuries or longer. Entrainment of hot primitive olivines into cooler, evolved carrier melts drives post-entrapment crystallization and sequestration of CO2 into vapour bubbles, producing spurious barometric estimates. While scavenged melt inclusion records may not be suitable for the investigation of eruption-specific processes, they record timescales of crystal storage and remobilization within magmatic mush piles.

RESUMO

PURPOSE: A growing number of biopharmaceutical companies have been implementing patient-centric initiatives (PCIs). The Drug Information Association (DIA) and the Tufts Center for the Study of Drug Development (CSDD) collaborated on a study to gather data on the usage and impact of these PCIs to characterize company experience and impact. METHODS: DIA and Tufts CSDD collaborated with 17 organizations to define PCIs used in clinical research and development and to quantify their use, and to define metrics in use to document impact and return on engagement (ROE) for these PCIs. The study used a mixed methods approach that consisted of an online survey, in-depth interviews, and literature review. FINDINGS: Twenty-two unique companies responded to an on-line survey on the use of 23 PCIs identified by the study working group. PCIs most frequently implemented included patient organization landscape analysis, support of patient advocacy groups, use of patient advisory boards, and use of home nursing networks. Seven additional PCIs were found through a literature search and included in the group of PCIs for which impact measures were assessed. A total of 121 cases of use of the 30 PCIs and associated impact measures and impact data were gathered through literature review, in-depth interviews with the study companies, and in-depth interviews with organizations identified in the literature as having experience with patient engagement in clinical research as well as with patients who had participated in clinical trials. Analysis of the 121 case studies resulted in a list of 666 measures of impact (metrics) in use for 13 of the PCIs. Assessment of overall ROE for these PCIs found that PCIs such as support of patient advocacy groups and use of patient advisory boards indicated the greatest ROE, whereas costlier, more complex PCIs such as digital medicine and gaming indicated relatively low ROE. IMPLICATIONS: Activity around PCIs among the companies studied was widespread, with initiatives more frequently planned and piloted than implemented at the time of this study. Measures of impact have been identified and can be used to assess ROE, providing insights to facilitate the adoption of PCIs of highest impact for patients and biopharmaceutical research organizations.

RESUMO

BACKGROUND: This pilot trial aimed to study the feasibility and effects on quality of life (QOL) and well-being of short-term fasting (STF) during chemotherapy in patients with gynecological cancer. METHODS: In an individually-randomized cross-over trial patients with gynecological cancer, 4 to 6 planned chemotherapy cycles were included. Thirty-four patients were randomized to STF in the first half of chemotherapies followed by normocaloric diet (group A;n = 18) or vice versa (group B;n = 16). Fasting started 36 h before and ended 24 h after chemotherapy (60 h-fasting period). QOL was assessed by the FACIT-measurement system. RESULTS: The chemotherapy-induced reduction of QOL was less than the Minimally Important Difference (MID; FACT-G = 5) with STF but greater than the MID for non-fasted periods. The mean chemotherapy-induced deterioration of total FACIT-F was 10.4 ± 5.3 for fasted and 27.0 ± 6.3 for non-fasted cycles in group A and 14.1 ± 5.6 for non-fasted and 11.0 ± 5.6 for fasted cycles in group B. There were no serious adverse effects. CONCLUSION: STF during chemotherapy is well tolerated and appears to improve QOL and fatigue during chemotherapy. Larger studies should prove the effect of STF as an adjunct to chemotherapy. TRIAL REGISTRATION: This trial was registered at clinicaltrials.gov: NCT01954836 .

RESUMO

The Cardiac Safety Research Consortium (CSRC), a transparent, public-private partnership established in 2005 as a Critical Path Program and formalized in 2006 under a Memorandum of Understanding between the United States Food and Drug Administration and Duke University, is entering its second decade. Our continuing goal is to advance paradigms for more efficient regulatory science related to the cardiovascular safety of new therapeutics, both in the United States and globally, particularly where such safety questions add burden to innovative research and development. Operationally, CSRC brings together a broad base of stakeholders from academia, industry, and government agencies in a collaborative forum focused on identifying barriers and then creating novel solutions through shared data, expertise, and collaborative research. This white paper provides a brief overview of the Consortium's activities in its first decade and a context for some of our current activities and future directions. The growth and success of the CSRC have been primarily driven by members' active participation and the development of goodwill and trust throughout our membership, which have facilitated novel collaborations across traditionally competitive or contentious stakeholder boundaries. The continued expansion of our base of participating academicians, industry experts, and regulators will define the Consortium's success in our second decade. It is our hope that sharing our endeavors to date will stimulate additional participation in the CSRC and also provide a model for other groups starting to develop similar collaborative forums.
