1 · What the graph read from it

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.

2 · The registry

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

purposeTo compare the pharmacokinetics (PK) of MNRP1685A, a human monoclonal antibody (mAb) against neuropilin-1 (NRP1), in mice, rats, monkeys, and cancer patients from a Phase I study to model with parallel linear and nonlinear clearances.

methodsBinding characteristics of MNRP1685A in different species were evaluated using surface plasmon resonance technology. PK profiles of MNRP1685A after single and/or multiple doses in different species were analyzed using population analysis. PK parameters were compared across species.

resultsMNRP1685A binds to NRP1 in all four species tested. Consistent with the wide expression of NRP1, MNRP1685A demonstrated pronounced non-linear PK over a wide dose range. PK profiles are best described by a two-compartment model with parallel linear and nonlinear clearances. Model-derived PK parameters suggest similar in-vivo target expression levels and binding affinity to target across all species tested. However, compared to typical human/humanized mAbs, non-specific clearance of MNRP1685A was faster in mice, rats, and humans (60.3, 19.4, and 8.5 ml/day/kg), but not in monkeys (3.22 ml/day/kg).

conclusionsMonkey PK properly predicted the target-mediated clearance of MNRP1685A but underestimated its non-specific clearance in humans. This unique PK property warrants further investigation of underlying mechanisms.
