Background And Purpose:
There is an unmet need for a more effective thrombolytic agent in acute ischemic stroke (AIS) management. Various studies and meta-analysis suggest tenecteplase (TNK) as non-inferior over alteplase (rTPA). The present single-center study compares biosimilar TNK and rTPA in a tertiary care setting.
Methods:
Data of patients who presented with AIS and underwent intravenous thrombolysis (IVT) were recruited retrospectively from January 2018 to July 2021. Primary efficacy outcome was a modified Rankin score (mRS) at 90 days dichotomized at < = 2. Qualitative and quantitative variables were assessed using Chi-square test and Student's t-test, respectively.
Results:
A total of 160 patients, 103 in the rTPA and 57 in TNK group, were analyzed. The baseline characteristics were well matched apart from hypertension. Large artery atherosclerosis was the most frequent subtype of stroke among the two groups. Good functional outcome was seen in 47.92% of patients TNK and 64.77% of patients in rTPA group (p = 0.069). No difference was seen in the rates of any ICH (p = 0.29) and mortality at 3 months (p = 0.32) among the two groups.
Conclusion:
This present study observed no difference in the efficacy and safety between biosimilar TNK and rTPA. Our findings are in concordance with published trials showing equivalence between the two molecules.
