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.

Topical tacrolimus with custom trays in the treatment of severe oral chronic graft-versus-host disease refractory to a potent topical steroid therapy: a case report.

BACKGROUND: The authors present a case demonstrating the success of topical tacrolimus (TAC) therapy with custom trays in the treatment of oral chronic graft-versus-host disease (cGVHD). The 41-year-old male patient initially responded to topical steroid therapy (clobetasol propionate 0.05% ointment) applied both topically and with flexible carrier trays, but later became refractory to this potent topical agent. Topical TAC therapy with flexible carrier trays and systemic prednisone therapy was initiated. RESULTS: The patient responded favorably with the change to topical TAC therapy with custom trays (and oral prednisone). His oral cGVHD lesions resolved within a period of 4 weeks. The improvement has remained stable at 14 months of follow-up. CLINICAL IMPLICATIONS: This is the first case reported with regard to the successful resolution of steroid recalcitrant cGVHD successfully treated with topical TAC with custom trays.

Bosutinib: a second-generation tyrosine kinase inhibitor for chronic myelogenous leukemia.

OBJECTIVE: To review clinical trials and main characteristics of bosutinib, a second-generation tyrosine kinase inhibitor (TKI) for treatment of chronic myelogenous leukemia (CML). DATA SOURCES: Pertinent data were identified through a search of PubMed (January 1990-April 2013) using the primary search terms SKI-606, bosutinib, and CML. Additionally, preliminary reports published in abstract form by the American Society of Clinical Oncology and American Society of Hematology (January 1990-April 2013) were screened for inclusion. STUDY SELECTION AND DATA EXTRACTION: Clinical Phase 1, 2, and 3 studies reported in English evaluating the safety and efficacy of bosutinib in patients with CML were reviewed. DATA SYNTHESIS: Bosutinib is a TKI of the breakpoint cluster region/Abelson murine leukemia (BCR-ABL) gene approved by the Food and Drug Administration on September 4, 2012, for second-line treatment of chronic phase, accelerated phase, and blast phase CML. In the second-line setting, bosutinib is effective in some patients with CML resistant or intolerant to imatinib, dasatinib, and/or nilotinib, but it is not effective in patients whose disease expresses the T315I point mutation in BCR-ABL. Bosutinib also has been compared with imatinib, the standard first-line treatment, in 502 patients with newly diagnosed chronic phase CML in a Phase 3 trial. Complete cytogenetic response at 12 months, the primary efficacy end point, is similar between bosutinib and imatinib (p = 0.601); therefore, bosutinib is not indicated in the first-line setting. Common adverse events associated with bosutinib include diarrhea, nausea, and vomiting. Grade 3 and 4 adverse events reported in at least 5% of bosutinib-treated patients include elevated serum lipase and liver aminotransferases, anemia, thrombocytopenia, neutropenia, and diarrhea. CONCLUSIONS: Currently available clinical trials suggest that bosutinib is generally a safe and effective treatment option for patients with CML who have failed first-line TKIs and who do not express the T315I mutation; however, tolerability may be problematic for some patients.
