Asciminib Chronic Phase Chronic Myeloid Leukemia: A Real-World Single Institution Case Series
INTRODUCTION
The development of imatinib and now newer tyrosine kinase inhibitors (TKIs) has revolutionized the overall survival of patients with CML. However, toxicity and treatment-resistance can result in premature discontinuation of therapy. Asciminib, a novel TKI, may have fewer off-target effects. It also bypasses the mechanism of resistance to first-line TKIs by binding to a different site on the BCR-ABL fusion protein. In our institution, three patients have been initiated on asciminib thus far. We present their cases, with a focus on quality of life.
CASE PRESENTATIONS
(1) A 76-year-old male with a history of diffuse vascular disease experienced off-target effects on multiple TKIs (i.e. intolerable nausea on imatinib, pleural effusion on dasatinib, complete heart block on nilotinib), so he was switched to asciminib. He has been tolerating asciminib well over five months and continues to see significant log reduction in BCR-ABL transcripts. (2) A 71-year-old male with a history of multiple complicated gastrointestinal infections never achieved major molecular remission on imatinib and was unable to tolerate dasatinib or bosutinib due to severe nausea and vomiting. He was switched to asciminib, which he has been tolerating well for one year, and has achieved complete hematologic response. (3) A 73-year-old male with a history of chronic kidney disease experienced kidney injury thought to be due to imatinib and was switched to bosutinib. His BCRABL transcripts rose on bosutinib, so patient was started on asciminib, which he has been tolerating well.
DISCUSSION
In this series of patients in their 70s with multiple underlying comorbidities, the unifying theme is that of intolerance to first-line TKIs due to toxicity (cardiac, pulmonary, gastrointestinal, and renal). Existing data suggests that asciminib results in less toxicity than other first-line TKIs, and this is evident in our patients. More importantly, the combination of efficacy and tolerability gives these patients the opportunity to proceed with life-prolonging therapy, even for those who face treatment resistance with other agents.
CONCLUSIONS
For CML patients who have failed at least two lines of treatment, whether it is due to disease progression or intolerable toxicity, asciminib is an effective alternative. Further study may result in its promotion to first-line therapy for this disease.

Creation of a National Virtual Tumor Board Through the National TeleOncology Service
Background
There is unequal access to subspecialty oncology expertise across the Veterans Affairs (VA) network. To address this need, the VA established National TeleOncology (NTO), which provides multiple virtual services (asynchronous [electronic consult] and synchronous [phone, video to home, video to facility]) to over 20 VA sites. Beyond these care modalities, a virtual tumor board was conceived to provide a forum for multidisciplinary review of patient cases. We describe the creation of the first NTO virtual tumor board, encompassing malignant hematology diagnoses.
Observations
Tumor boards are considered a standard of care. While challenging to quantify nationally, multiple single institution experiences have established the importance of tumor boards across different measures. A panel of stakeholders were convened to discuss the creation of a virtual tumor board. Best practices and standard operating procedures were created based on guidance from relevant literature and internal VA experience. Participants from specialties including medical oncology, surgical oncology, radiology, pathology, transplant, and palliative care were engaged from eight different VA medical centers across the nation. On March 2, 2022, the initial tumor board was held allowing for synchronous virtual review of patient pathology and imaging. Thus far 6 tumor boards have been convened, reviewing 11 patients originating from 6 different VA sites.
Results
A participant survey was conducted after 4 sessions, which indicated that all who completed the survey (n = 9) found the sessions beneficial or somewhat beneficial, and 55% found the sessions highly applicable to their practice. The most recent tumor board had 33 participants (physicians, nurses, advanced practice practitioners, and pharmacists).
Conclusions
The establishment of a national VA tumor board represents a novel approach to the review of oncology cases across the VA network. The goal of this tumor board is to leverage the diverse knowledge base that exists within the VA to deliver equitable care regardless of veteran location. Along with improving our general understanding of tumor board application, we believe that the NTO tumor board establishes a unique forum for additional tumor types, continued medical education opportunities, and the review of VA clinical trial opportunities.
