BACKGROUND: Pending results from double-blind, multicenter, parallel-group,
randomized trials, the benefit and safety of the novel plasminogen activator,
desmoteplase remain undetermined. The aim of this meta-analysis was to help
evaluate desmoteplase's efficacy and safety. METHODS: A thorough search was
performed of the Cochrane Library, PubMed, and Embase from the inception of
electronic data to March 2017, and double-blind, multicenter, parallel-group,
randomized trials were chosen. We conducted a meta-analysis of studies
investigating intravenous desmoteplase treatment of acute ischemic stroke
patients 3 to 9 hours after symptom onset. Asymptomatic intracerebral hemorrhage,
good clinical outcome at 90 days, and reperfusion 4 to 8 hours posttreatment were
variables assessing efficacy; symptomatic intracerebral hemorrhage and death
rates were measures of safety. RESULTS: Six trials involving 1071 patients
thrombolyzed >3 hours postonset were included (600 received intravenous
desmoteplase, 471 placebo). Desmoteplase was associated with increased
reperfusion (odds ratio [OR] 1.57; 95% confidence interval [CI], 1.10-2.24;
P?=?.01 vs control) and showed a tendency to increase asymptomatic intracerebral
hemorrhage (OR 1.25; 95% CI, 0.97-1.62; P?=?.09 vs control), whereas there was no
increase in symptomatic intracerebral hemorrhage and death rate with
desmoteplase. However, there was no difference in the clinical response at 90
days (OR 1.14; 95% CI, 0.88-1.49; P?=?.31 vs control). Subgroup analysis showed
that desmoteplase 90??g/kg (OR 1.53; 95% CI, 1.07-2.21; P?=?.02 vs control) and
125??g/kg (OR 4.07; 95% CI, 1.16-14.24; P?=?.03 vs control) were associated with
an increase in reperfusion. Also, we found desmoteplase 90??g/kg showed a
tendency to increase asymptomatic intracerebral hemorrhage (OR 1.25; 95% CI,
0.95-1.63; P?=?.11 vs control). CONCLUSION: Intravenous desmoteplase is
associated with a favorable reperfusion efficacy and acceptable safety in
ischemic stroke treatment >3 hours after symptom onset. Well-designed randomized
controlled trials with larger patient cohorts and a moderate dose of drugs are
needed to further evaluate the true efficacy of desmoteplase in stroke patients.
