Abstract

Monoclonal antibody biotherapeutics are often administered by subcutaneous (SC) injection. Due to dose requirements and formulation limitations, SC injections >1 mL are often required. We used a viscous placebo buffer (5 cP), characteristic of a high-concentration antibody formulation, to investigate the effect of dose volume and injection rate on the tolerability of higher-volume SC injections. In this randomized, crossover, single-center study, 48 healthy adults received one 1.2-mL bolus injection over 5 s and three 3.5-mL injections over 1, 4, and 10 min in different abdominal quadrants, with each injection separated by approximately 2 h. The primary objective was to compare pain scores associated with the injections, immediately after administration and 1 h later, using a 100-mm visual analog scale (VAS). Secondary objectives included assessment of adverse events, including injection site reactions and swelling. Mean age was 38.4 (11.6) years and 20 subjects (42%) were female. Lowest mean VAS score was for the 10-min (6.83 mm) and highest for the 1-min injection (19.13 mm). One hour after administration, mean VAS scores were <3.5 mm for all injections. Swelling was similar among the three 3.5-mL injections. After needle removal, leakage occurred following 14 (29%) 1.2-mL injections, eight (17%) 4-min injections, five (10%) 1-min injections, and four (8%) 10-min injections. Fifteen subjects (31%) experienced an adverse event, none of which was serious, fatal, or led to study discontinuation. All injection durations were well tolerated, suggesting a single large-volume SC injection of a biotherapeutic agent could be used instead of multiple injections.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
