Transitioning Therapeutic Antibodies in Oncology from Intravenous to Hyaluronidase-Facilitated Subcutaneous Administration.
Review in Clinical pharmacokinetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Intravenous (IV) infusion remains the predominant delivery route for oncology monoclonal antibodies, but it requires prolonged chair time and substantial infusion-unit resources. Hyaluronidase-facilitated subcutaneous (SC) formulations aim to shorten administration (minutes vs hours), improve convenience, and potentially expand outpatient or home-based delivery, while preserving exposure, efficacy, and safety. We conducted a narrative review of published clinical studies, major congress presentations, trial registries, and Food and Drug Administration (FDA)/European Medicines Agency (EMA) regulatory documents describing development of hyaluronidase-facilitated SC formulations for seven oncology antibodies (trastuzumab, rituximab, daratumumab, atezolizumab, nivolumab, pembrolizumab, and amivantamab). We extracted evidence on formulation strategy, pharmacokinetic (PK) bridging, efficacy comparability, safety/immunogenicity, and regulatory pathways supporting IV→SC approval. Across programs, PH20-based recombinant hyaluronidases, including human hyaluronidase PH20 (rHuPH20) and berahyaluronidase alfa, transiently depolymerize SC hyaluronan, enabling delivery of multi-milliliter injections and high fixed doses. Development strategies converged on PK-anchored bridging, typically targeting non-inferior SC/IV geometric-mean ratios for both initiation and maintenance exposure (e.g., cycle-1 area under the curve [AUC]/average plasma concentration [C
