An Industry Perspective on Risks and Mitigation Strategies Associated with Post Conduct Phase of Clinical Trial.

OBJECTIVE: To discuss the potential risks and their mitigation strategies in the post-conduct phase of the trial. BACKGROUND: Risk management is very important for the clinical trial (CT) to ensure that the trial delivers its desired outcome(s) in terms of achieving protocol objective and regulatory compliance. METHODOLOGY: Experienced members of the clinical operation team of a pharmaceutical major underwent a series of sessions to identify risks associated with the post-conduct phase of CT and developed mitigation strategies based on own experiences and guidance documents. The risks were categorized into major, minor and critical risks. RESULTS: In the post-conduct phase of a clinical trial, critical risk identified were; failure to communicate to the stakeholder about premature termination of the trial, mismatch of statistical analysis results and protocol objective/ regulatory requirement, clinical study report (CSR) noncompliant with regulatory requirements or delay in CSR preparation. Safety checks suggested to mitigate these risks including the development of related checklist or shell of relevant documents and its review by clinical development, quality assurance (QA) and regulatory affairs (RA) team prior to finalization. Additionally, six major and five minor risk areas were identified and safety checks were suggested. CONCLUSION: Sponsors must act proactively to ensure a systematic approach to conduct various post conduct trial activities and the plans to mitigate the risks that could affect the quality and outcome of the clinical trial. Future Perspective: A close coordination with all stakeholders for timely anticipation of risks and execution of mitigation strategies are required for successful CT outcomes.

In vitro activity of a novel antibacterial agent, levonadifloxacin, against clinical isolates collected in a prospective, multicentre surveillance study in India during 2016-18.

BACKGROUND: Levonadifloxacin is a novel antibiotic belonging to the benzoquinolizine subclass of fluoroquinolones with potent activity against MRSA and quinolone-resistant Staphylococcus aureus. IV levonadifloxacin and its oral prodrug alalevonadifloxacin have recently been approved in India for the treatment of acute bacterial skin and skin structure infections (ABSSSIs) including diabetic foot infections. OBJECTIVES: To investigate the in vitro activity of levonadifloxacin against contemporary clinical isolates collected from multiple tertiary care hospitals across India in the Antimicrobial Susceptibility Profiling of Indian Resistotypes (ASPIRE) surveillance study. METHODS: A total of 1376 clinical isolates, consisting of staphylococci (n = 677), streptococci (n = 178), Enterobacterales (n = 320), Pseudomonas aeruginosa (n = 140) and Acinetobacter baumannii (n = 61), collected (2016-18) from 16 tertiary hospitals located across 12 states in India, were included in the study. The MICs of levonadifloxacin and comparator antibiotics were determined using the reference agar dilution method and broth microdilution method. RESULTS: Levonadifloxacin exhibited potent activity against MSSA (MIC50/90: 0.5/1 mg/L), MRSA (MIC50/90: 0.5/1 mg/L) and levofloxacin-resistant S. aureus (MIC50/90: 1/1 mg/L) isolates. Similarly, potent activity of levonadifloxacin was also observed against CoNS including MDR isolates (MIC50/90: 1/2 mg/L). Against Streptococcus pneumoniae, levonadifloxacin (MIC50/90: 0.5/0.5 mg/L) showed superior activity compared with levofloxacin (MIC50/90: 1/2 mg/L). Among levofloxacin-susceptible Enterobacterales, 80.6% of isolates were inhibited at ≤2 mg/L levonadifloxacin. CONCLUSIONS: Levonadifloxacin displayed potent activity against contemporary MRSA and fluoroquinolone-resistant staphylococcal isolates, thus offering a valuable IV as well as an oral therapeutic option for the treatment of ABSSSIs. Furthermore, levonadifloxacin exhibited a broad-spectrum activity profile as evident from its activity against streptococci and levofloxacin-susceptible Gram-negative isolates.

Potential Risks and Mitigation Strategies During the Conduct of a Clinical Trial: An Industry Perspective.

BACKGROUND: Every phase of a clinical trial should be designed in compliance with good clinical practices by following all relevant regulatory guidelines. Patient safety, data integrity and ethics are an integral part of a successful clinical trial which must be considered. Therefore, risk monitoring is an essential tool to identify the risks associated with conduct of any trial. This article is a result of extensive research conducted by a reputed pharmaceutical company to identify the potential stages of risks associated with the conduct phase of trial that could impact the overall quality and safety of a trial. METHODS: The skillful and experienced team members of a reputed pharmaceutical company involved in conducting clinical trials underwent brainstorming sessions to assess and categorize the risks associated with each stage of conduct phase of a clinical trial. They also developed a mitigation plan based on their experiences, best practices and applicable guidance documents. RESULTS: During conduct phase, risks are associated with preparation of site master and trial master file, courier of study supply to site(s) including investigational product prior to site initiation visit, patient recruitment, telephonic monitoring, adverse or serious adverse event monitoring, site monitoring visit(s), collected case report form pages forward to data management vendor, data query clarification and site close-out visit. CONCLUSION: A close working relationship with all the persons associated with the clinical trial, timely monitoring and prospective mitigation planning is required for the conduct of a high quality trial.
