On April 17 2020, the United States Food and Drug Administration granted
Coronavirus Disease 2019 (COVID-19) emergency use authorizations for the Seraph
100 Microbind Affinity Blood Filter. The medical device is aimed to treat
critically ill COVID-19 patients with confirmed or imminent respiratory failure.
The aim of this life size in vitro pharmacokinetic study was to investigate the
in vitro adsorption of chloroquine and hydroxychloroquine from human plasma using
equipment that is also used at the bedside. After start of the hemoperfusion, Pre
(C(pre) ) Seraph plasma levels were obtained at 5 (C(5) ), 10 (C(10) ), 15 (C(15)
), 30 (C(30) ), 60 (C(60) ), and 120 (C(120) ) minutes into the procedure. At two
timepoints (5 and 120?minutes) post (C(post) ) Seraph plasma levels were
determined that were used to calculate the plasma clearance of the Seraph. Both
drugs were determined using a validated HPLC method. Median [IQR] plasma
clearance of the Seraph for chloroquine/hydroxychloroquine was 1.71 [0.51-4.38]
mL/min/1.79 [0.21-3.68] mL/min respectively. The lack of elimination was also
confirmed by the fact that plasma levels did not change over the 120?minutes
treatment. As neither chloroquine nor hydroxychloroquine were removed by the
treatment with the Seraph dose adjustments in COVID-19 patients undergoing this
treatment are not necessary.
