Clinical, Journal, HEOR: Clinical and economic benefits of lenzilumab plus standard of care compared with standard of care alone for the treatment of hospitalized patients with COVID-19 in the United States from the hospital perspective. (Pubmed Central) - Feb 15, 2022 When adding rehospitalization costs to the index hospitalization, a total per-patient cost savings of $5,154 was estimated. The results highlight the clinical benefits for SWOV, ventilator use, time to recovery, mortality, time in ICU, and time on IMV, in addition to an economic benefit from the US hospital perspective associated with adding lenzilumab to SOC for COVID-19 patients.

Lenzilumab in Hospitalized Black/African-American COVID-19 Patients: Live-Air Phase 3 Study Results ([VIRTUAL]) - Feb 8, 2022 - Abstract #SCCM2022SCCM_853; In LIVE-AIR, with a B/AA representation comparable to the US population and usually under-represented in trials, lenzilumab improved the likelihood of SWOV across races and ethnicities of COVID-19 patients; however, B/AA with baseline CRP< 150 mg/L exhibited a markedly greater improvement. Biological, genetic, and social factors contributing to these differences requires further investigation.

Optimized Inhibition of GM-CSF in Preclinical Models of Anti-CD19 Chimeric Antigen Receptor T Cell Therapy (Salt Palace Convention Center Hall A) - Jan 9, 2022 - Abstract #TCTASTCTCIBMTR2022TCT_ASTCT_CIBMTR_864; Having demonstrated that GM-CSFRα is significantly upregulated on stimulated CART19, we aimed to determine the impact of GM-CSF neutralization (lenzilumab, 10 µg/mL) versus GM-CSFRα blockade (research-grade, 10 µg/mL) on CART19 function and CART cell-monocyte interactions...Flow cytometric analysis revealed that GM-CSF neutralization, but not GM-CSFRα blockade, mitigated monocyte suppression of CART19 antigen specific proliferation (Fig 1B). In summary, our findings indicate significant differences on CART cell functions and CART cell-monocyte interactions when a specific cytokine, GM-CSF, is neutralized compared to blocking its receptor.
