AryoSeven RT (Coagulation factor VIIa, recombinant) safety and efficacy study among congenial factor VII deficient patients in Iraq

Abstract

BACKGROUND: Recombinant activated factor VII (FVII) is a product onetime evolved to stop bleeding occurring in hemophilia A and B patients with inhibitor, congenital FVII deficiency, Glanzmann disease, and in life-threatening bleeding. AIM: The aim was to evaluate the safety and efficacy of the coagulation factor VIIa, recombinant (AryoSeven RT) among congenital FVII deficiency patients at different centers in Iraq. METHODOLOGY: This is a prospective, observational, noninterventional study done at 5 medical centers in Iraq and it included 22 patients with FVII deficiency (congenital form) older than 14 years of age. Patients are recorded and followed for 6 months and they are subjected to AryoSeven RT depending on each patient individually. There were 3 main visits and 3 unscheduled visits for each patient during the study. Effectiveness evaluation was performed 6 h after each intervention. Adverse drug reactions related to the administration of AryoSeven RT were reported for each patient during each visit. RESULTS: A total of 22 participants were enrolled, classified into 18 (82%) were female and 4 (18%) were male. The mean age was 27.5 ± 14.0 years. Among 91 bleeding events, AryoSeven RT efficacy was effective in 89 events, excellent in 1 event, and partially effective in also 1 event. There was a reduction of PT from baseline (57.3 ± 15.2 s) to (13.9 ± 6.2 s) after 1st dose of AryoSeven RT and more reduction after 2nd dose of therapy (13.4 ± 4.4 s) and these were statistically significant (P = 0.001). Regarding FVII activity, there was a significant increase from baseline (8.4% ± 8.0%) to (95.8% ± 46.6%) after 1st dose and (131.8% ± 40.1%) after 2nd dose of AryoSeven RT with P = 0.001 for both. No major adverse events were reported except for headache in one participant (4.5%), and injection site reactions in three participants (13.6%).) CONCLUSION: AryoSeven RT is safe and effective clinically and by laboratory data in stopping bleeding in patients older than 14 years with inherited FVII deficiency.
