A phase II trial of netupitant/palonosetron for prevention of chemotherapy-induced nausea/vomiting in patients receiving BEAM prior to hematopoietic cell transplantation.

Objective: The purpose of this study was to investigate the efficacy and safety of netupitant/palonosetron (NEPA) for the prevention of chemotherapy-induced nausea and vomiting (CINV) for hematopoietic cell transplantation (HCT) patients receiving BEAM therapy. Study Design: This phase II, prospective, intention-to-treat, single-center, single-arm study involved 43 adult patients who received NEPA and dexamethasone for the prevention of CINV due to BEAM conditioning chemotherapy. An interim analysis, performed after 13 patients, determined utility versus futility, and supported continuation to full enrollment. Descriptive statistics were used to report complete response (CR), complete protection, incidence of emesis, and administration of rescue agents. A Kaplan-Meier curve depicted time to first emesis and first rescue medication. Patients self-reported levels of daily nausea descriptively via a CINV Questionnaire. Results: By study end, 13 of 43 patients achieved a CR with an average of 10.6 emesis-free days (SD 0.95) over the 11-day observation period, with no emetic events in any patient during the acute/chemotherapy phase. Nausea was well-controlled throughout the acute therapy phase (Day 1-6) and increased during the delayed phase (Day 7-11) with a peak mean level of 2.79/10 at Day 10. Aside from lower grade (≤2), headaches, constipation, and diarrhea were the most widely reported adverse effects. Conclusion: The combination of NEPA and dexamethasone is safe and effective for the prevention of CINV in patients receiving BEAM conditioning therapy prior to HCT. The regimen demonstrated greater effectiveness in the acute phase versus the delayed phase, with low levels of nausea throughout the study period and complete emesis prevention during chemotherapy.

Pneumocystis jirovecii Pneumonia Prophylaxis with Intravenous Pentamidine in Adult Allogeneic Hematopoietic Stem Cell Transplant Patients.

The purpose of this single-center retrospective case series was to evaluate the efficacy and safety of 300-mg once-monthly intravenous (IV) pentamidine prophylaxis in 702 adult allogeneic hematopoietic stem cell transplant (HSCT) patients. We observed no cases of Pneumocystis jirovecii pneumonia (PJP) following IV pentamidine administration. Breakthrough Nocardia and Toxoplasma infections were observed in 7 (1%) and 5 (0.7%) patients, respectively. The most commonly reported adverse event was nausea. Monthly IV pentamidine is a reasonable alternative to trimethoprim-sulfamethoxazole (TMP-SMX).

Comparative effects of fluconazole, posaconazole, and isavuconazole upon tacrolimus and cyclosporine serum concentrations.

INTRODUCTION: Calcineurin inhibitors are commonly used in hematopoietic stem cell transplant (HSCT) patients to prevent graft versus host disease, but as CYP3A4 substrates they are frequently involved in drug-drug interactions. The purpose of this study is to characterize the effects of isavuconazole, fluconazole, and posaconazole on tacrolimus and cyclosporine serum concentrations and dose adjustments in allogeneic HSCT patients. METHODS: This retrospective study included patients admitted to Oregon Health and Science University between April 2008 and December 2018 who underwent hematopoietic stem cell transplantation and received concomitant tacrolimus or cyclosporine and fluconazole, isavuconazole or posaconazole therapy. Data on patient characteristics, drug dosing, and serum drug concentrations were collected through chart review, and descriptive statistics were used to summarize the results. RESULTS: A total of 139 patients were included in this study. We found fluconazole initiation leads to a 25% reduction in both tacrolimus and cyclosporine doses in order to maintain goal serum concentrations. Posaconazole and isavuconazole initiation requires tacrolimus dose reductions by 53% and 21%, respectively. CONCLUSIONS: Based on our experience, FLC, POS, and ISA initiation may require CNI dose reductions and close monitoring of CNI levels to ensure levels remain within goal serum concentrations. Larger studies are needed to fully quantify the percentage in CNI dose reductions and characterize differences among these antifungals.

Graft-versus-host disease after liver transplantation is associated with bone marrow failure, hemophagocytosis, and DNMT3A mutations.

Graft-versus-host disease after liver transplantation (LT-GVHD) is rare, frequently fatal, and associated with bone marrow failure (BMF), cytopenias, and hyperferritinemia. Given hyperferritinemia and cytopenias are present in hemophagocytic lymphohistiocytosis (HLH), and somatic mutations in hematopoietic cells are associated with hyperinflammatory responses (clonal hematopoiesis of indeterminate potential, CHIP), we identified the frequency of hemophagocytosis and CHIP mutations in LT-GVHD. We reviewed bone marrow aspirates and biopsies, quantified blood/marrow chimerism, and performed next-generation sequencing (NGS) with a targeted panel of genes relevant to myeloid malignancies, CHIP, and BMF. In all, 12 marrows were reviewed from 9 LT-GVHD patients. In all, 10 aspirates were evaluable for hemophagocytosis; 7 had adequate DNA for NGS. NGS was also performed on marrow from an LT cohort (n = 6) without GVHD. Nine of 10 aspirates in LT-GVHD patients showed increased hemophagocytosis. Five (71%) of 7 with LT-GVHD had DNMT3A mutations; only 1 of 6 in the non-GVHD LT cohort demonstrated DNMT3A mutation (p = .04). Only 1 LT-GVHD patient survived. BMF with HLH features was associated with poor hematopoietic recovery, and DNMT3A mutations were over-represented, in LT-GVHD patients. Identification of HLH features may guide prognosis and therapeutics. Further studies are needed to clarify the origin and impact of CHIP mutations on the hyperinflammatory state.

Capsule-related dysphagia and the use of netupitant/palonosetron (Akynzeo™) capsules - A report of two cases and a solution.

Netupitant/palonestron (NEPA, Akynzeo™) is a fixed combination of netupitant 300 mg and palonosetron 0.5 mg that is indicated for the prevention of chemotherapy-induced nausea and vomiting (CINV). NEPA is supplied as a hard gelatin capsule and indicated to be administered whole with or without food. The efficacy of NEPA was maintained when administered as an oral dose of netupitant given concomitantly (in separate formulations after removal from the hard gelatin capsule) with a single oral dose of palonosetron. At our institution, two patients experienced difficulty swallowing the capsule leading to opening the capsule and individual administration of the medications. We observed that the efficacy was maintained when the opened NEPA capsule was administered as individual medications. We report the details of these two patient cases.

A survey of global biosimilar implementation practice conducted by the International Society of Oncology Pharmacy Practitioners.

Background: The International Society of Oncology Pharmacy Practitioners (ISOPP) Biosimilars Task Force was charged to develop educational activities and resources to assist members when implementing biosimilar medicines into their local practice. To facilitate the process, the task force conducted a survey in order to understand biosimilar implementation practice by ISOPP members across the world and the challenges that oncology pharmacists face when adopting biosimilars into their clinical practice. Methods: A cross-sectional survey was conducted between 20 April 2019 and 27 May 2019. Members of ISOPP and a number of national oncology pharmacy groups were invited to complete the survey. The survey contained 29 items and consisted of three sections: respondents' demographics, respondents' institutional practice relating to biosimilar implementation and post implementation practice at the respondents' institutions. Descriptive statistics were utilized to analyze the survey results. Results: A total of 265 ISOPP members were surveyed, with 50 members providing a response (response rate = 19%). In addition, 40 nonmembers participated in the survey, bringing the total to 90 respondents. The most common factors that influence the decision to implement use of a biosimilar as reported by respondents are medication costs/pricing (92%), available clinical data (73%), and product availability (63%). Respondents also commented on the barriers to biosimilar implementation at their institutions, which included a reluctance of prescribers to use biosimilars (due to the lack of familiarity or perceived inferiority), a reluctance to switch established patients from an originator to a biosimilar and the preferences of insurance companies or funding bodies. Conclusion: The results of this survey reinforce the need for greater education and training for health care professionals in the use of biosimilars, the importance of sharing good practice, and a need for standardization.

Assessing biosimilar education needs among oncology pharmacy practitioners worldwide: An ISOPP membership survey.

Background: The International Society of Oncology Pharmacy Practitioners (ISOPP) Biosimilar Task Force was charged to develop educational resources to address the learning needs related to biosimilars use of oncology pharmacy practitioners. To facilitate the process, the task force conducted a survey in order to identify unmet education needs as well as barriers for obtaining biosimilar education among oncology pharmacy practitioners. Methods: A cross sectional survey was conducted between 10 December 2018 and 18 February 2019. Members of International Society of Oncology Pharmacy Practitioners and national oncology pharmacy groups were invited to complete the survey. The survey contained 22 items and consisted of four sections. Descriptive statistics were utilized to analyze the survey results. Results: A total of 363 International Society of Oncology Pharmacy Practitioners members were surveyed, with 75 members providing a response (response rate = 21%). In addition, 11 non-International Society of Oncology Pharmacy Practitioners members also participated in the survey, bringing the total to 86 respondents. The top three areas in which respondents reported learning needs included evaluating comparative efficacy of a biosimilar to an originator's product (74.4%), managing the switchover to a biosimilar from the original product (74.4%), and understanding medication safety issues in relation to biosimilars use (73.3%). The most common challenges faced in obtaining education on biosimilars included limited financial support for education on biosimilar products (38.4%), heavy workload (31.4%), and inadequate educational resources (27.9%). Conclusion: This survey has identified numerous biosimilar learning needs as well as challenges faced in obtaining biosimilars education among oncology pharmacy practitioners. Educational activities should be created to address these learning needs, and innovative strategies should be considered to overcome practitioner's barriers in obtaining biosimilars education.

International Society of Oncology Pharmacy Practitioners global position on the use of biosimilars in cancer treatment and supportive care.

With the development of innovative cancer treatments over recent decades, the cost of cancer care has risen exponentially, limiting patient access to patented originator biotherapeutics in many countries. The introduction of biosimilars to the market has created new opportunities as well the need for changes in practice within healthcare institutions. A 'biosimilar' is a biotherapeutic product which is highly similar in terms of quality, safety and efficacy to an already licensed originator product. Although biosimilars lack clinically meaningful differences in therapeutic activity as compared to the originator product, these complex biological molecules are not considered identical chemical copies, unlike generics, and minor differences in molecular structure and inactive compounds may exist. A thorough understanding of these differences and their clinical implications is necessary for optimising medicines-use practices involving biosimilars. This position statement, developed by the International Society of Oncology Pharmacy Practitioners Biosimilars Taskforce, aims to provide the global oncology pharmacy community with guidance to support decisions around biosimilar use. The 11 statements cover the regulation and evaluation of biosimilars, practical issues around local implementation, the education of healthcare staff and patients, and the requirement for ongoing pharmacovigilance and outcome monitoring.

Association of Antiepileptic Medications with Outcomes after Allogeneic Hematopoietic Cell Transplantation with Busulfan/Cyclophosphamide Conditioning.

High-dose busulfan (BU) followed by high-dose cyclophosphamide (CY) before allogeneic hematopoietic cell transplantation (HCT) has long been used as treatment for hematologic malignancies. Administration of phenytoin or newer alternative antiepileptic medications (AEMs) prevents seizures caused by BU. Phenytoin induces enzymes that increase exposure to active CY metabolites in vivo, whereas alternative AEMs do not have this effect. Lower exposure to active CY metabolites with the use of alternative AEMs could decrease the risk of toxicity but might increase the risk of recurrent malignancy after HCT. Previous studies have not determined whether outcomes with alternative AEMs differ from those with phenytoin in patients treated with BU/CY before allogeneic HCT. We studied a cohort of 2155 patients, including 1460 treated with phenytoin and 695 treated with alternative AEMs, who received BU/CY before allogeneic HCT between 2004 and 2014. We found no differences suggesting decreased overall survival or relapse-free survival or increased risks of relapse, nonrelapse mortality, acute or chronic graft-versus-host disease, or regimen-related toxicity associated with the use of alternative AEMs compared with phenytoin. The risk of dialysis was lower in the alternative AEM group than in the phenytoin group. Alternative AEMs are safe for prevention of seizures after BU administration and can avoid the undesirable toxicities and drug interactions caused by phenytoin.

Effect of Conditioning Regimen Dose Reduction in Obese Patients Undergoing Autologous Hematopoietic Cell Transplantation.

Data are limited on whether to adjust high-dose chemotherapy before autologous hematopoietic cell transplant (autoHCT) in obese patients. This study explores the effects of dose adjustment on the outcomes of obese patients, defined as body mass index (BMI) ≥ 30 kg/m2. Dose adjustment was defined as a reduction in standard dosing ≥20%, based on ideal, reported dosing and actual weights. We included 2 groups of US patients who had received autoHCT between 2008 and 2014. Specifically, we included patients with multiple myeloma (MM, n = 1696) treated with high-dose melphalan and patients with Hodgkin or non-Hodgkin lymphomas (n = 781) who received carmustine, etoposide, cytarabine, and melphalan conditioning. Chemotherapy dose was adjusted in 1324 patients (78%) with MM and 608 patients (78%) with lymphoma. Age, sex, BMI, race, performance score, comorbidity index, and disease features (stage at diagnosis, disease status, and time to transplant) were similar between dose groups. In multivariate analyses for MM, adjusting for melphalan dose and for center effect had no impact on overall survival (P = .894) and treatment-related mortality (TRM) (P = .62), progression (P = .12), and progression-free survival (PFS; P = .178). In multivariate analyses for lymphoma, adjusting chemotherapy doses did not affect survival (P = .176), TRM (P = .802), relapse (P = .633), or PFS (P = .812). No center effect was observed in lymphoma. This study demonstrates that adjusting chemotherapy dose before autoHCT in obese patients with MM and lymphoma does not influence mortality. These results do not support adjusting chemotherapy dose in this population.

Clinical Outcomes of Oral Suspension versus Delayed-Release Tablet Formulations of Posaconazole for Prophylaxis of Invasive Fungal Infections.

Posaconazole is used for prophylaxis for invasive fungal infections (IFIs) among patients with hematologic malignancies. We compared the incidence of breakthrough IFIs and early discontinuation between patients receiving delayed-release tablet and oral suspension formulations of posaconazole. This was a retrospective cohort study of patients receiving posaconazole between 1 January 2010 and 30 June 2016. We defined probable or proven breakthrough IFIs using the European Organization for Research and Treatment of Cancer (EORTC) criteria. Overall, 547 patients received 860 courses of posaconazole (53% received the oral suspension and 48% received the tablet); primary indications for prophylaxis were acute myeloid leukemia (69%), graft-versus-host disease (18%), and myelodysplastic syndrome (3%). There were no significant differences in demographics or indications between patients receiving the different formulations. The incidence and incidence rate of probable or proven IFIs were 1.6% and 3.2 per 10,000 posaconazole days, respectively. There was no significant difference in the rate of IFIs between suspension courses (2.8 per 10,000 posaconazole days) and tablet courses (3.7 per 10,000 posaconazole days) (rate ratio = 0.8, 95% confidence interval [CI] = 0.3 to 2.3). Of the 14 proven or probable cases of IFI, 8/14 had posaconazole serum concentrations measured, and the concentrations in 7/8 were above 0.7 µg/ml. Posaconazole was discontinued early in 15.5% of courses; however, the frequency of discontinuation was also not significantly different between the tablet (16.5%) and oral suspension (14.6%) formulations (95% CI for difference = -0.13 to 0.06). In conclusion, the incidence of breakthrough IFIs was low among patients receiving posaconazole prophylaxis and not significantly different between patients receiving the tablet formulation and those receiving the oral suspension formulation.

Phase II open label pilot trial of aprepitant and palonosetron for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving moderately emetogenic FOLFOX chemotherapy for the treatment of colorectal cancer.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) causes significant morbidity among colorectal cancer patients, receiving fluorouracil, oxaliplatin, and leucovorin (FOLFOX) chemotherapy even with standard antiemetic prophylaxis. The purpose of this study is to determine if the addition of aprepitant to standard antiemetic therapy improves CINV in these patients. METHODS: Patients receiving FOLFOX for colorectal cancer were given antiemetic prophylaxis with aprepitant 125 mg orally on day 1 and 80 mg on days 2 and 3. Palonosetron 0.25 mg was given IV push on day 1 only. Dexamethasone 12 mg was administered orally on day 1 and 8 mg each morning on days 2 through 4. Assessments including emetic events, rescue doses, nutritional intake, and appetite were recorded in a patient diary which was returned to study personnel in the following cycle. RESULTS: Of the 53 patients screened, 50 were evaluable and had a complete dataset for cycle 1. For the first cycle, 74% of patients achieved a complete response (CR), 22% achieved a major response and 4% experienced treatment failure. The percentage of patients achieving a CR remained high throughout each cycle at 83, 83, and 86% for cycles 2, 3, and 4, respectively. Appetite and nutritional status remained largely unchanged throughout treatment. Adverse events occurring in more than 10% of patients included diarrhea (13.6%), fatigue (12.6%), and neutropenia (11%). CONCLUSIONS: Aprepitant added to standard antiemetic therapy appears to be an effective and safe regimen for prevention of CINV in patients receiving FOLFOX.

Personalizing Busulfan-Based Conditioning: Considerations from the American Society for Blood and Marrow Transplantation Practice Guidelines Committee.

The Practice Guidelines Committee of the American Society of Blood or Marrow Transplantation (ASBMT) sought to develop an evidence-based review about personalizing busulfan-based conditioning. The Committee sought to grade the relevant published studies (June 1, 2008 through March 31, 2016) according to criteria set forth by the Steering Committee for Evidence Based Reviews from ASBMT. Unfortunately, the published literature was too heterogeneous and lacked adequately powered and sufficiently controlled studies for this to be feasible. Despite this observation, the continued interest in this topic led the Practice Guidelines Committee to develop a list of most frequently asked questions (FAQs) regarding personalized busulfan dosing. This "Considerations" document is a list of these FAQs and their responses, addressing topics of practical relevance to hematopoietic cell transplantation clinicians.

Posaconazole Tablet Formulation at 400 Milligrams Daily Achieves Desired Minimum Serum Concentrations in Adult Patients with a Hematologic Malignancy or Stem Cell Transplant.

We describe our experience using the posaconazole 400-mg delayed-release tablet formulation once daily in 20 patients with hematologic malignancy or hematopoietic stem cell transplant who were unable to attain prespecified target minimum serum (trough) concentrations for treatment or prophylaxis of invasive fungal infection. The higher dose allowed the majority of patients to achieve prespecified target trough concentrations without incurring additional toxicities.

Comparison of posaconazole serum concentrations from haematological cancer patients on posaconazole tablet and oral suspension for treatment and prevention of invasive fungal infections.

Posaconazole tablet formulation (PTF) was developed to optimise bioavailability. This study compared posaconazole levels between patients on the PTF and oral suspension formulation (OSF). We also examined factors that may impact posaconazole levels. The primary and secondary objectives were analysed by comparing trough levels and attainment of target level between the formulation groups. For the 86 patients on PTF and 176 on OSF, the mean first levels was 1.32 µg ml-1 (SD = 0.69) and 0.81 µg ml-1 (SD = 0.59), P < 0.0001 respectively. PTF group was more likely to achieve levels ≥0.7 µg ml-1 than OSF group (OR 7.97 [95 CI; 3.75-16.93], P < 0.0001). Levels from patients on PTF and with presence of acid suppression, GI GVHD, mucositis or diarrhoea were not statistically different from those without these factors. For PTF, no correlation was found between patient's weight (kg) and levels (R2 = 0.0536, P = 0.035). The incidences of elevation in ALT/AST or Tbili were similar between the formulation groups. In conclusion, PTF should be considered the preferred formulation because it demonstrated better absorption than the OSF. Patients on PTF for prophylaxis are more likely to attain target level and may not routinely require therapeutic drug monitoring during prophylaxis.

Conditioning chemotherapy dose adjustment in obese patients: a review and position statement by the American Society for Blood and Marrow Transplantation practice guideline committee.

Hematopoietic stem cell transplantation (HCT) is a potentially life-saving therapy for patients with malignant and nonmalignant disease states. This article reviews the current published literature on the dosing of pharmacologic agents used for HCT preparative regimens with specific focus on the obese patient population. The review found that dose adjustments for obesity have, to date, been based empirically or extrapolated from published data in the nontransplantation patient population. As a result, the Committee determined that clear standards or dosing guidelines are unable to be made for the obese population because Level I and II evidence are unavailable at this time. Instead, the Committee provides a current published literature review to serve as a platform for conditioning agent dose selection in the setting of obesity. A necessary goal should be to encourage future prospective trials in this patient population because further information is needed to enhance our knowledge of the pharmacokinetics and pharmacodynamics of conditioning agents in the setting of obesity.

Evaluation and implementation of chemotherapy regimen validation in an electronic health record.

INTRODUCTION: Computerized provider order entry of chemotherapy regimens is quickly becoming the standard for prescribing chemotherapy in both inpatient and ambulatory settings. One of the difficulties with implementation of chemotherapy regimen computerized provider order entry lies in verifying the accuracy and completeness of all regimens built in the system library. Our goal was to develop, implement, and evaluate a process for validating chemotherapy regimens in an electronic health record. METHODS: We describe our experience developing and implementing a process for validating chemotherapy regimens in the setting of a standard, commercially available computerized provider order entry system. The pilot project focused on validating chemotherapy regimens in the adult inpatient oncology setting and adult ambulatory hematologic malignancy setting. RESULTS: A chemotherapy regimen validation process was defined as a result of the pilot project. Over a 27-week pilot period, 32 chemotherapy regimens were validated using the process we developed. Results of the study suggest that by validating chemotherapy regimens, the amount of time spent by pharmacists in daily chemotherapy review was decreased. In addition, the number of pharmacist modifications required to make regimens complete and accurate were decreased. Both physician and pharmacy disciplines showed improved satisfaction and confidence levels with chemotherapy regimens after implementation of the validation system. CONCLUSION: Chemotherapy regimen validation required a considerable amount of planning and time but resulted in increased pharmacist efficiency and improved provider confidence and satisfaction.

Does applying technology throughout the medication use process improve patient safety with antineoplastics?

PURPOSE: Medical errors, in particular medication errors, continue to be a troublesome factor in the delivery of safe and effective patient care. Antineoplastic agents represent a group of medications highly susceptible to medication errors due to their complex regimens and narrow therapeutic indices. As the majority of these medication errors are frequently associated with breakdowns in poorly defined systems, developing technologies and evolving workflows seem to be a logical approach to provide added safeguards against medication errors. SUMMARY: This article will review both the pros and cons of today's technologies and their ability to simplify the medication use process, reduce medication errors, improve documentation, improve healthcare costs and increase provider efficiency as relates to the use of antineoplastic therapy throughout the medication use process. Several technologies, mainly computerized provider order entry (CPOE), barcode medication administration (BCMA), smart pumps, electronic medication administration record (eMAR), and telepharmacy, have been well described and proven to reduce medication errors, improve adherence to quality metrics, and/or improve healthcare costs in a broad scope of patients. The utilization of these technologies during antineoplastic therapy is weak at best and lacking for most. Specific to the antineoplastic medication use system, the only technology with data to adequately support a claim of reduced medication errors is CPOE. In addition to the benefits these technologies can provide, it is also important to recognize their potential to induce new types of errors and inefficiencies which can negatively impact patient care. CONCLUSION: The utilization of technology reduces but does not eliminate the potential for error. The evidence base to support technology in preventing medication errors is limited in general but even more deficient in the realm of antineoplastic therapy. Though CPOE has the best evidence to support its use in the antineoplastic population, benefit from many other technologies may have to be inferred based on data from other patient populations. As health systems begin to widely adopt and implement new technologies it is important to critically assess their effectiveness in improving patient safety.

Transplantation-Associated Altered Mentation and Encephalopathy: A New Classification for Acute Neurocognitive Changes Associated with Hematopoietic Cell Transplantation from the ASTCT Committee on Practice Guidelines.

Acute encephalopathy, manifesting clinically as delirium, is a common but often unrecognized complication of hematopoietic cell transplantation (HCT). Delirium can occur in patients of any age and is observed after autologous or allogeneic HCT. Although delirium has been studied primarily during initial HCT hospitalizations in recipients of myeloablative conditioning, recent investigations have identified delirium later post-transplantation and in recipients of reduced-intensity conditioning. Acute encephalopathy can be driven by infectious complications, medications, tissue damage, and/or organ dysfunction. Altered consciousness, either mild or profound, is often its only clinical manifestation. Identifying delirium is essential to overall HCT care, because patients who experience delirium have longer hospitalization and recovery times and are at risk for other poor post-HCT outcomes. Given the critical nature of this common complication and the ongoing expansion of HCT for more vulnerable populations, the American Society of Transplantation and Cellular Therapy (ASTCT) recommends intensifying research into post-HCT cognitive changes and establishing standardized definitions that encompass the full spectrum of altered consciousness for clinical care purposes and to provide benchmark endpoints for future research studies. To capture a range of acute neurocognitive changes specifically found in HCT patients (often referred to as acute encephalopathy), the ASTCT proposes a new diagnosis, transplantation-associated altered mentation and encephalopathy (TAME). The TAME diagnosis includes HCT patients who meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for delirium and those with acute neurocognitive changes who do not meet all the DSM-5 criteria for delirium (subsyndromal delirium). Early TAME is defined as occurring during conditioning or ≤100 days post-HCT, whereas late TAME occurs >100 days post-HCT in patients with additional HCT-related complications. This manuscript establishes clear diagnostic criteria and discusses factors that can potentially impact the development of TAME, as well as the workup and management of TAME.

Utilization of collaborative practice agreements between physicians and pharmacists as a mechanism to increase capacity to care for hematopoietic stem cell transplant recipients.

Survival after hematopoietic stem cell transplantation (HSCT) has improved and the number of allogeneic HSCTs performed annually in the United States is expected to reach 10,000 by 2015. The National Marrow Donor Program created the System Capacity Initiative to formulate mechanisms to care for the growing number of HSCT recipients. One proposed method to increase capacity is utilization of pharmacists to manage drug therapy via collaborative practice agreements (CPAs). Pharmacists have managed drug therapy in oncology patients with CPAs for decades; however, there are limited HSCT centers that employ this practice. Engaging in collaborative practice and billing agreements with credentialed pharmacists to manage therapeutic drug monitoring, chronic medical conditions, and supportive care in HSCT recipients may be cost-effective and enable physicians to spend more time on new or more complex patients. The goal of this paper is to provide a framework for implementation of a CPA and address how it may improve HSCT program capacity.
