Phase 3 | 536 | Margetuximab + Chemotherapy | qzaxhbrkar(svztbiqluk) = A higher proportion of patients experienced IRRs on the M arm (35 [13.3%]) than on the T arm (9 [3.4%]). Most IRRs in both groups were severity Grade 1 or 2, occurred on Cycle 1 Day 1, and resolved within 24 hours. In patients receiving M, Grade 3 IRR occurred in 4 patients (1.5%), including 3 after vinorelbine and 1 after eribulin. Adverse events associated with Grade 3 IRRs included chills, fever, nausea, diarrhea, dyspnea, and/or hypertension. Two patients receiving M (0.8%) discontinued due to IRR, versus none on T. Of patients with IRRs, the most common symptoms in both treatment groups were chills (M: 17 [48.6%]; T: 5 [55.6%]) and fever (M: 13 [37.1%]; T: 2 [22.2%]). There was no observed hypotension in either group. In both groups, more than half of IRR events were addressed by dose interruption only. All IRRs all were medically manageable. IRR rates were higher in patients without premedication for both groups. Of 264 subjects receiving M, 218 (82.6%) received premedication and 46 (17.4%) did not; IRRs were observed in 28 (12.8%) of those receiving premedication and 7 (15.2%) of those not premedicated. All 4 patients on M with Grade 3 IRRs received premedication, 3 with steroids. Of 266 subjects receiving T, 173 (65%) received premedication and 93 (35%) did not; IRRs were observed in 5 (2.9%) of those receiving premedication and 4 (4.3%) of those not premedicated. IRR risk was unaffected by chemotherapy subgroup or CD16A genotype. papngvfitl (aermgomgrp ) | Positive | 15 Feb 2021 | ||
