For drugs with enhanced serious safety risks, Risk Evaluation and Mitigation Strategy (REMS) may be required. Pexidartinib is approved for treatment of adult symptomatic tenosynovial giant cell tumor (TGCT) associated with severe morbidity or functional limitations and not amenable to improvement with surgery. Its approval was conditional on its prescription via a mandatory REMS due to serious and potentially fatal liver injury seen in clinical trials. Turalio® REMS aims to mitigate this risk by ensuring provider education on pexidartinib use and required REMS components, prescriber adherence to baseline and periodic monitoring, and enrolling patients in a registry to further assess safe use and acute, chronic and irreversible hepatotoxicity. Through Turalio REMS, benefits of treating patients with pexidartinib may be preserved.
Background: Without treatment, acute myeloid leukemia (AML) is rapidly fatal. Nevertheless, a large proportion of elderly AML patients do not receive any treatment. Aim: To characterize the demographics, comorbidities, survival and prognostic factors of elderly AML patients who do not receive any AML treatment or supportive care (SC). Methods: A retrospective cohort analysis of the Surveillance, Epidemiology and End Results-Medicare database (2008–2015). Results: Of 7665 AML patients, 2373 (31%) did not receive any AML treatment or SC. The mean age was 80.4 years, 52.8% were males and 79.7% and 95.3% died within the first 60 and 180 days, respectively; 2.1% survived >12 months and only 5.5% of patients had remission or relapse codes populated. Conclusion: Older age, male gender, concurrent depression, ischemic heart disease, chronic kidney disease and benign prostatic hyperplasia were associated with a decreased likelihood of survival. Multiple factors contribute to the complex clinical status of these patients preventing intensive chemotherapy; they should still ideally be treated, at least with the best SC.
Aim: Elderly acute myeloid leukemia (AML) patients are often not treated with antileukemic therapy due to their poor overall health condition, leaving supportive care as the sole treatment option. Objective: To evaluate patient characteristics, treatment patterns and outcomes of elderly patients with AML who are treated with supportive care only. Methods: A retrospective analysis of elderly AML patients included in the Surveillance, Epidemiology and End Results-Medicare database from 2008 to 2015. Results: Of elderly patients with AML (n = 7665), 3209 (41.9%) received supportive care only. Their mean age was 79 years, 50.5% were males; 48.2% died during the first 3 months and 67.3% died during the first 6 months. 82.2% died within the first year; only 13.2% survived >12 months. 77.9% patients died due to leukemia. Conclusion: In elderly AML patients treated with supportive care only, older age, concurrent hypertension, chronic obstructive pulmonary disease, chronic kidney disease and acute myocardial infarction were identified as prognostic factors associated with decreased likelihood of survival. Ideally, these patients should be treated with antileukemic therapy in addition to supportive care, as most of them die from disease progression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
