Analysis of integrated clinical trial protocols in early phases of medicinal product development.

ABSTRACT:

Purpose

While in the past, most clinical trial applications (CTAs) following non-integrated (standard) protocols were used to investigate one primary objective concerning a (new) drug, nowadays, the use of integrated protocols investigating multiple objectives within the same CTA becomes more and more popular. The aims of the present study were to investigate the usage and the impact of integrated protocols on regulatory activities and to find the motivation for their increasing use.

Methods

Two thousand nine hundred sixty-nine phase I and I/II CTAs submitted to the German Federal Institute for Drugs and Medical Devices (BfArM) during the time period from August 1, 2004, until August 31, 2014, were analysed with regard to protocol and sponsor status, duration until initial authorisation and the number of substantial amendments and their respective approval times. Additionally, applicants who submitted integrated protocols to BfArM were interviewed with respect to their opinion on integrated protocols in an online survey.

Results

The percentage of integrated protocols has constantly increased by approximately 10% within the last 10 years from 17.9% in 2004 to 28.2% in 2014. It could be shown that authorisation procedures with single integrated protocols take significantly longer until initial authorisation (58 vs. 53 days) requires more substantial amendments (1.9 vs. 1.2 amendments per CTA) and the approval of the entirety of amendments takes longer to process as compared to standard protocols (22 vs. 14 days). Nevertheless, applicants prefer the use of integrated protocols due to higher time and cost economy for the entire phase I development process.

Conclusion

Although clinical trials (CTs) following integrated protocols are partly more time-consuming and costly, still, time and/or money may be saved during drug development due to the fact that overall, fewer CTs are needed than with standard protocols. Hence, the main reason for the increasing use of integrated protocols is improved time and cost efficiencies when conducting CTs.

Project description:The COVID-19 pandemic caused considerable disruption to the development, regulatory evaluation, production, and distribution of medicinal products. Key healthcare stakeholders were under pressure to develop and review medicinal products to address the health emergency, while preserving the continuity of activities to ensure patient access to other medicinal products. In the light of this challenging situation, the National Regulatory Authorities (NRAs) and the biopharmaceutical industry applied and utilized product development and regulatory agilities to accelerate the development and authorization of safe, effective and quality COVID-19 vaccines and treatments as well as other non-COVID-19 medicinal products. On the basis of the literature review and primary research conducted, this review article gathered insights on experiences and challenges in the use of agilities related to regulatory assessment of initial marketing and post-approval change (PAC) applications, oversight of product manufacturing quality and supply chain continuity, and product development/clinical trial processes during the early phases of the COVID-19 pandemic. Agilities were thus implemented in an emergency context characterized by the lack of medicinal products to help tackle a disease that was devastating for the global public health. This review article concludes that useful lessons can be learned from these insights to improve product development practices and regulatory processes during both normal and health emergency times. Standard regulatory frameworks during normal times can be enhanced by leveraging digitalization, further simplifying and harmonizing requirements, and using reliance mechanisms which can help to increase efficiency in regulatory decision-making regarding medicinal products. During health emergencies, such as a pandemic, maximizing global coordination, collaboration, reliance, and harmonization of regulatory requirements and guidance are important to facilitate the rapid development and assessment of key medicinal products to address the health emergency.

Project description:ImportanceLimited data suggest that early palliative care (EPC) improves quality of life (QOL) and survival in patients with advanced cancer.ObjectiveTo evaluate whether comprehensive EPC improves QOL; relieves mental, social, and existential burdens; increases survival rates; and helps patients develop coping skills.Design, setting, and participantsThis nonblinded randomized clinical trial (RCT) recruited patients from 12 hospitals in South Korea from September 2017 to October 2018. Patients aged 20 years or older with advanced cancer who were not terminally ill but for whom standard chemotherapy has not been effective were eligible. Participants were randomized 1:1 to the control (receiving usual supportive oncological care) or intervention (receiving EPC with usual oncological care) group. Intention-to-treat data analysis was conducted between September and December 2022.InterventionsThe intervention group received EPC through a structured program of self-study education materials, telephone coaching, and regular assessments by an integrated palliative care team.Main outcomes and measuresThe primary outcome was the change in overall QOL score (assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative Care) from baseline to 24 weeks after enrollment, with evaluations also conducted at 12 and 18 weeks. Secondary outcomes were social and existential burdens (assessed with the McGill Quality of Life Questionnaire) as well as crisis-overcoming capacity and 2-year survival.ResultsA total of 144 patients (83 males [57.6%]; mean [SD] age, 60.7 (7.2) years) were enrolled, of whom 73 were randomized to the intervention group and 71 to the control group. The intervention group demonstrated significantly greater changes in scores in overall health status or QOL from baseline, especially at 18 weeks (11.00 [95% CI, 0.78-21.22] points; P = .04; effect size = 0.42). However, at 12 and 24 weeks, there were no significant differences observed. Compared with the control group, the intervention group also showed significant improvement in self-management or coping skills over 24 weeks (20.51 [95% CI, 12.41-28.61] points; P < .001; effect size = 0.93). While the overall survival rate was higher in the intervention vs control group, the difference was not significant. In the intervention group, however, those who received 10 or more EPC interventions (eg, telephone coaching sessions and care team meetings) showed a significantly increased probability of 2-year survival (53.6%; P < .001).Conclusions and relevanceThis RCT demonstrated that EPC enhanced QOL at 18 weeks; however, no significant improvements were observed at 12 and 24 weeks. An increased number of interventions sessions was associated with increased 2-year survival rates in the intervention group.Trial registrationClinicalTrials.gov Identifier: NCT03181854.
