Studies of generic imatinib evaluating the pharmacologic properties and bioequivalence

AuthorsCountryStudy typeSample sizeResults and comments
Grillo et al10  Argentina In vitro NA Original imatinib was produced in β-crystal form while generics mostly in α-crystal form which was observed as less stable than β-form in room temperature 
Yokoo et al11  Japan In vitro NA Comparable OS rates with original and generic imatinib in CML cell lines 
Parrillo-Campiglia et al19  Uruguay In vivo 30 Mean test/reference ratios for AUC and Cmax:95% and 97% (CI: 90%), respectively 
Ostrowicz et al18  Poland In vivo 80 Comparable Tmax, Cmax, AUC0-24 values with original and generic imatinib. Acceptable therapeutic limits (90-111.11%) for generic product 
Malhotra et al14  India In vivo 131 Comparable mean imatinib trough levels with original imatinib (n = 84) and generic (n = 47; P = .079) 
Ostojic et al12  Croatia In vivo 24 75% of branded and 89% and 100% of generic pts achieved IPC ≥ 1000 ng/mL 
Arora et al17  India In vivo 42 Mean test/reference Cmax and AUC0-24 ratios: 99% and 99.2%, respectively (P = .78 and P = .99; CI: 90%) 
Natarajan et al13  India In vivo 206 All patients (original = 130, generics = 76) reached plasma concentration above 1000 ng/ml (P = .964).
