Show moreAim: Evaluate health-related quality of life (HRQoL) and health utility impact of single-agent selinexor in heavily pretreated patients with relapsed/refractory diffuse large B-cell lymphoma. Patients & methods: Functional Assessment of Cancer Therapy (FACT) - Lymphoma and EuroQoL five-dimensions five-levels data collected in the single-arm Phase IIb trial SADAL (NCT02227251) were analyzed with mixed-effects models. Results: Treatment responders maintained higher FACT - Lymphoma (p <= 0.05), FACT - General (p < 0.05) and EuroQoL five-dimensions five-levels index scores (p < 0.001) beginning in cycle 3. The estimated difference in health state utilities for treatment response and progressive disease was both statistically significant and clinically meaningful (mean difference: 0.07; p = 0.001). Conclusion: In patients with relapsed/refractory diffuse large B-cell lymphoma, objective response to selinexor was associated with HRQoL maintenance, reduction in disease-related HRQoL decrements and higher health utilities.Lay abstractThis work examined quality of life (QoL) among patients with relapsed/refractory diffuse large B-cell lymphoma with two to five prior therapies who received single-agent selinexor in the SADAL clinical trial. Analysis of patient-reported Functional Assessment of Cancer Therapy - Lymphoma and EuroQoL five-dimensions five-levels data showed that patients who had objective clinical response to selinexor maintained their QoL over the course of treatment. Grade >= 3 adverse events and serious adverse events were not associated with clinically meaningful negative QoL impacts. Show less
