Study to assess the impact of analytics software on operating room controlled substance management and drug diversion.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: This study investigated the impact of an advanced analytics software solution in the operating room (OR) on tracking and evaluating controlled substance discrepancies. The authors hypothesized that the software would increase identification of these discrepancies and improve the efficiency of the preexisting manual process. METHODS: In this evaluation comparing data from before to after implementation of the software, data were collected using the preexisting manual process for 50 days before implementation, followed by a 25-day period for acclimation to the new software, and ending with a 49-day postimplementation review period. Data collected included the total number of medication discrepancies, time required for discrepancy review and reconciliation by an OR analyst, types of discrepancies, and number of discrepancies leading to provider audits. RESULTS: Before implementation of the analytics software, there were 7,635 OR cases with a total of 674 charting discrepancies (8.83 discrepancies per 100 total OR cases) discovered across 439 OR cases. After implementation, there were 7,454 OR cases with a total of 930 charting discrepancies (12.48 discrepancies per 100 total OR cases; P < 0.0001) discovered across 680 OR cases. While discrepancies increased by 38%, the median review time for the OR analyst per case decreased (P < 0.0001) and the percentage of incidents resolved by the OR analyst increased by 14% while the number of cases requiring additional documentation by the provider decreased by 10%. CONCLUSION: Implementation of advanced analytics software in the OR significantly increased the number of controlled substance charting discrepancies identified compared to the preimplementation review process while increasing the efficiency of the OR analyst.

Recommendations for Method Development and Validation of qPCR and dPCR Assays in Support of Cell and Gene Therapy Drug Development.

The emerging use of qPCR and dPCR in regulated bioanalysis and absence of regulatory guidance on assay validations for these platforms has resulted in discussions on lack of harmonization on assay design and appropriate acceptance criteria for these assays. Both qPCR and dPCR are extensively used to answer bioanalytical questions for novel modalities such as cell and gene therapies. Following cross-industry conversations on the lack of information and guidelines for these assays, an American Association of Pharmaceutical Scientists working group was formed to address these gaps by bringing together 37 industry experts from 24 organizations to discuss best practices to gain a better understanding in the industry and facilitate filings to health authorities. Herein, this team provides considerations on assay design, development, and validation testing for PCR assays that are used in cell and gene therapies including (1) biodistribution; (2) transgene expression; (3) viral shedding; (4) and persistence or cellular kinetics of cell therapies.

Validation of Anti-Adeno Associated Virus Serotype rh10 (AAVrh.10) Total and Neutralizing Antibody Immunogenicity Assays.

Immunogenicity assessment of Adeno-Associated Virus (AAV) vectors is a critical part of gene therapy drug development. Whether the assays are used for inclusion/exclusion criteria or to monitor the safety and efficacy of the gene therapy, they are critical bioanalytical assessments. While total anti-AAV assays are perceived as easier to develop and implement than neutralizing anti-AAV assays, the gene therapy field is still nascent, and it is not yet clear which of the assays should be implemented at what stage of drug development. Recently AAVrh.10 has gained interest for use in gene therapies targeting cardiac, neurological, and other diseases due to its enhanced transduction efficiency. There is limited information on anti-AAVrh.10 antibodies and their clinical impact; thus, the information presented herein documents the validation of both a total antibody assay (TAb) and a neutralizing antibody (NAb) assay for anti-AAVrh.10 antibodies. In this manuscript, the validation was performed in accordance with the 2019 FDA immunogenicity guidance with additional evaluations to comply with CLIA where applicable. The AAVrh.10 TAb and NAb assays were compared in terms of sensitivity, drug tolerance, and precision, along with a concordance analysis using the same individual serum samples. This comparison gave insight into the utility of each format as a screening assay for inclusion into clinical studies.

Neutralizing Antibody Validation Testing and Reporting Harmonization.

Evolving immunogenicity assay performance expectations and a lack of harmonized neutralizing antibody validation testing and reporting tools have resulted in significant time spent by health authorities and sponsors on resolving filing queries. A team of experts within the American Association of Pharmaceutical Scientists' Therapeutic Product Immunogenicity Community across industry and the Food and Drug Administration addressed challenges unique to cell-based and non-cell-based neutralizing antibody assays. Harmonization of validation expectations and data reporting will facilitate filings to health authorities and are described in this manuscript. This team provides validation testing and reporting strategies and tools for the following assessments: (1) format selection; (2) cut point; (3) assay acceptance criteria; (4) control precision; (5) sensitivity including positive control selection and performance tracking; (6) negative control selection; (7) selectivity/specificity including matrix interference, hemolysis, lipemia, bilirubin, concomitant medications, and structurally similar analytes; (8) drug tolerance; (9) target tolerance; (10) sample stability; and (11) assay robustness.

Utilization of a technology-assisted workflow to prepare controlled substance oral syringes.

PURPOSE: Utilization of technology-assisted workflow (TAWF) systems has gained popularity in the sterile compounding setting. This study was designed to evaluate whether safety and efficiency could be seen when preparing oral controlled substance doses gravimetrically vs volumetrically. METHODS: This 2-phase observational study combined manual data collection with automated logs generated by a single TAWF. During phase I, oral controlled substance solutions were prepared volumetrically. In phase II, the same subset of medications was to be prepared gravimetrically via the same TAWF. Findings from phases I and II were compared against each another to determine safety, efficiency, and documentation differences between the volumetric and gravimetric workflows. RESULTS: Thirteen different medications were evaluated during phase I (1,495 preparations) and phase II (1,781 preparations) of this study. Mean compounding time (min:sec) increased in phase II when compared to phase I (1:49 vs 1:28; P < 0.01), with the deviation detection rate also increasing (7.9% vs 4.7%; P < 0.01). Despite a target in phase II of utilizing gravimetric analysis for more than 80% of preparations, only 45.5% (811 preparations) were prepared with this workflow, as adoption challenges and dose size limitations prevented compliance. Doses that were prepared gravimetrically had a mean accuracy rate of 100.6% (the mean achieved dose was 0.6% higher than the mean prescribed dose) and a rejection rate of 0.99% (compared to the phase I rejection rate of 1.07%; P = 0.67). CONCLUSION: The gravimetric workflow provided accuracy and additional safety checks when compared to the volumetric alternative, all while providing users with greater access to data. Health systems should consider staffing, product sourcing, patient populations, and medication safety when determining the balance between volumetric and gravimetric workflows.

Anti-drug Antibody Sample Testing and Reporting Harmonization.

A clear scientific and operational need exists for harmonized bioanalytical immunogenicity study reporting to facilitate communication of immunogenicity findings and expedient review by industry and health authorities. To address these key bioanalytical reporting gaps and provide a report structure for documenting immunogenicity results, this cross-industry group was formed to establish harmonized recommendations and a develop a submission template to facilitate agency filings. Provided here are recommendations for reporting clinical anti-drug antibody (ADA) assay results using ligand-binding assay technologies. This publication describes the essential bioanalytical report (BAR) elements such as the method, critical reagents and equipment, study samples, results, and data analysis, and provides a template for a suggested structure for the ADA BAR. This publication focuses on the content and presentation of the bioanalytical ADA sample analysis report. The interpretation of immunogenicity data, including the evaluation of the impact of ADA on safety, exposure, and efficacy, is out of scope of this publication.

Recommendations on qPCR/ddPCR assay validation by GCC.

Gene therapy, cell therapy and vaccine research have led to an increased use of qPCR/ddPCR in bioanalytical laboratories. CROs are progressively undertaking the development and validation of qPCR and ddPCR assays. Currently, however, there is limited regulatory guidance for the use of qPCR and a complete lack of any regulatory guidelines for the use of the newer ddPCR to support regulated bioanalysis. Hence, the Global CRO Council in Bioanalysis (GCC) has issued this White Paper to provide; 1) a consensus on the different validation parameters required to support qPCR/ddPCR assays; 2) a harmonized approach to their validation and 3) a consistent development of standard operating procedures (SOPs) for all the bioanalytical laboratories using these techniques.

Recommendations on ELISpot assay validation by the GCC.

Gene therapy, cell therapy and vaccine research have led to an increased need to perform cellular immunity testing in a regulated environment to ensure the safety and efficacy of these treatments. The most common method for the measurement of cellular immunity has been Enzyme-Linked Immunospot assays. However, there is a lack of regulatory guidance available discussing the recommendations for developing and validating these types of assays. Hence, the Global CRO Council has issued this white paper to provide a consensus on the different validation parameters required to support Enzyme-Linked Immunospot assays and a harmonized and consistent approach to Enzyme-Linked Immunospot validation among contract research organizations.

Bioanalytical Assay Strategies and Considerations for Measuring Cellular Kinetics.

A vast evolution of drug modalities has occurred over the last several decades. Novel modalities such as cell and gene therapies have proven to be efficacious for numerous clinical indications-primarily in rare disease and immune oncology. Because of this success, drug developers are heavily investing in these novel modalities. Given the complexity of these therapeutics, a variety of bioanalytical techniques are employed to fully characterize the pharmacokinetics of these therapies in clinical studies. Industry trends indicate that quantitative PCR (qPCR) and multiparameter flow cytometry are both valuable in determining the pharmacokinetics, i.e. cellular kinetics, of cell therapies. This manuscript will evaluate the pros and cons of both techniques and highlight regulatory guidance on assays for measuring cellular kinetics. Moreover, common considerations when developing these assays will be addressed.

Deploying a rapid point-of-care polymerase chain reaction test for SARS-CoV-2 in a clinical research unit to ensure healthy volunteer safety.

The entire world was severely affected by the outbreak of the SARS-CoV-2 virus. Early phase clinical research was no exception and clinical healthy volunteer trials were halted across the globe. To enable continuation of development of new drugs, we developed a testing strategy for nonsymptomatic trial participants in an early stage of the outbreak. A point-of-care polymerase chain reaction test combined with a gold standard polymerase chain reaction test and strict social distancing and hygiene measures limited the number of infected subjects entering our clinical research units and reduced further spread for the duration of the clinical trial. Thus, proving efficacy of this strategy to allow safe and effective continuation of early phase clinical trials during the COVID-19 pandemic.

Recommendations for the content and management of Certificates of Analysis for reference standards from the GCC for bioanalysis.

The 13th Global CRO Council (GCC) closed forum for bioanalysis was held in New Orleans, LA, USA on 5 April 2019. This GCC meeting was organized to discuss the contents of the 2019 ICH M10 Bioanalytical Method Validation Draft Guideline published in February 2019 and consolidate the feedback of the GCC members. While ICH M10 will cover requirements for reference standards, one of the biggest challenges facing the CRO community is the lack of consistency and completeness of Certificates of Analysis for reference standards used in regulated bioanalysis. Similar challenges exist with critical reagents (e.g., capture and detection antibodies) used for assays supporting biologics. The recommendations provided in this publication are the minimum requirements for the content that GCC members believe should be included in Certificates of Analysis for reference standards obtained from commercial vendors, sponsors and compendial suppliers, for use in regulated bioanalytical studies. In addition, recommendations for internal standards, metabolites and critical reagents are discussed.

Extending flow cytometry sample stability by freezing lysed whole blood for clinical monitoring of Treg.

Aim: A major challenge for flow cytometry assays supporting clinical trials is postcollection sample stability. Here we present an approach that could mitigate the stability issue while preserving sample integrity and cellular markers, especially when enumerating rare populations such as Tregs. Materials & methods: Stability was evaluated using whole blood stored at room temperature and lysed whole blood stored at -80°C. Results: Freezing of lysed whole blood preserved sample integrity and prolonged sample stability for Treg percentage, absolute cell count and median fluorescent intensity values to 11 versus 3 days at room temperature storage. Conclusion: Frozen storage of lysed whole blood can extend sample stability, improve data quality and facilitate sample batch processing during clinical study sample analysis.

Development of an antimicrobial stewardship program in an integrated healthcare system.

PURPOSE: The development of an inpatient antimicrobial stewardship program (ASP) in an integrated healthcare system is described. SUMMARY: With increasing national focus on reducing inappropriate antimicrobial use, state and national regulatory mandates require hospitals to develop ASPs. In 2015, BJC HealthCare, a multihospital health system, developed a system-level, multidisciplinary ASP team to assist member hospitals with ASP implementation. A comprehensive gap analysis was performed to assess current stewardship resources, activities and compliance with CDC core elements at each facility. BJC system clinical leads facilitated the development of hospital-specific leadership support statements, identification of hospital pharmacy and medical leaders, and led development of staff and patient educational components. An antimicrobial-use data dashboard was created for reporting and tracking the impact of improvement activities. Hospital-level interventions were individualized based on the needs and resources at each facility. Hospital learnings were shared at bimonthly system ASP meetings to disseminate best practices. The initial gap analysis revealed that BJC hospitals were compliant in a median of 6 ASP elements (range, 4-8) required by regulatory mandates. By leveraging system resources, all hospitals were fully compliant with regulatory requirements by January 2017. CONCLUSION: BJC's ASP model facilitated the development of broad-based stewardship activities, including education modules for patients and providers and clinical decision support, while allowing hospitals to implement activities based on local needs and resource availability.
