What is Teicoplanin Hospira?
The main issue for consideration was the failure to demonstrate that Teicoplanin Hospira is a generic of Targocid.
The company that makes Teicoplanin Hospira, Hospira UK Limited, requested a re-examination of the opinion.
The CHMP noted thedata comparing the PK, PDD and safety of Teicoplanin Hospira and the originator.
Teicoplanin Hospira is a generic medicine based on a‘reference medicine' authorised in Germany(Targocid 400 mg).
Therefore, the Applicant considers Teicoplanin Hospira to be a generic of Targocid.
Teicoplanin Hospira can also be used to prevent infections in patients undergoing surgery of the bones, joint or blood vessels.
Questions and answers on the referral for Teicoplanin Hospira powder and solvent for injection containing 200 or 400 mg teicoplanin. .
Teicoplanin Hospira does not meet the originator specifications with respect to the individual glycopeptides subcomponents and has shown to be bio-inequivalent to the originator.
However, these results are not considered to demonstrate that Teicoplanin Hospira is a generic of Targocid, with regards to overall similarity.
The mouse thigh infection model study was considered to be representative of deep seated infections andprovides a comparison of the tissue penetration characteristics of Teicoplanin Hospira and Targocid.
As the ratios observed for Teicoplanin Hospira fall outside these ranges, equivalence cannot be assumed, based on the in vitro data alone.
The grounds for the referral were concerns from Ireland andthe United Kingdom that Teicoplanin Hospira had not been shown to be bioequivalent to Targocid.
These differences are indicative that Teicoplanin Hospira is not a generic of Targocid and the potential impact on the safety of the drug is still not clear.
All subcomponents are well characterised and readily identifiable andthere is no doubt that each individual subcomponent in Teicoplanin Hospira has the same characteristics as in Targocid.
However, AUC 0-tlast andAUC 0-inf were lower for Teicoplanin Hospira, indicating that PK equivalence was not shown for the total(bound plus unbound) drug exposure.
The Applicant examined both available active drug(free AUC) and whole drug and free AUC/MIC,concluding that Teicoplanin Hospira is at least as efficacious as Targocid.
In 2005 Hospira UK submitted applications for Decentralised Procedure for Teicoplanin Hospira 200 mg& 400 mg powder and solvent for solution for injection in the framework of Article 28 of Directive 2001/83/EC, as amended.
Question 1- The differences in composition between the two products andthe resulting differences between the AUC values do not clearly demonstrate that Teicoplanin Hospira and the reference product Targocid are essentially similar.
Teicoplanin Hospira can only be used in patients who cannot receive penicillin or cephalosporins antibiotics, or if these antibiotics have stopped working or the infection is due to a Staphylococcus that is resistant to other antibiotics.
The Applicant concluded that all the studies support the efficacy and safety of Teicoplanin Hospira and that the results were similar to those obtained with the originator.
On 25 June 2009, the European Medicines Agency(EMEA) completed an arbitration procedure following a disagreement among Member States of the European Union regarding the authorisation of the medicine Teicoplanin Hospira.
The CHMP assessed the studies andconcluded that the MIC results were similar between Teicoplanin Hospira and the originator and that no difference in antibacterial activity or in effectiveness was observed.
It was however noted that tissue concentrations of drug components were not measured and that regarding the toxicology,it cannot be concluded whether the products are comparable as the histopathology was investigated only for Teicoplanin Hospira.
The CHMP was of the opinion that compliance with the specifications of the European Pharmacopoeia does not automatically imply that Teicoplanin Hospira is a generic of Targocid and maintained that demonstrating this is crucial for approval.
Due to the differences in systemic exposure between Teicoplanin Hospira and Targocid and because the effect of the subcomponent differences on tissue drug concentrations was not measured, the CHMP concluded that bioequivalence could not be demonstrated.
The Applicant then defined the active ingredient by referring to the INN and the pharmacopoeial monographs,concluding that Teicoplanin Hospira meets all of the criteria necessary to define it as a generic of the originator product.
The study concluded that the biological activity of Teicoplanin Hospira is equivalent to that of Targocid and therefore confirmed that the minor differences in the composition of individual active components of teicoplanin do not affect the biological activity.
The pharmacokinetics of teicoplanin has been determined for both the total complex and for the individual components and analyses of the subcomponents confirmed that the pharmacokinetics of the individual TA2 subcomponents are the same for Teicoplanin Hospira and Targocid.
The Applicant considered that the PK results for whole teicoplanin demonstrated that Cmax and Tmax of Teicoplanin Hospira and Targocid were essentially similar, and the 90% CI for Cmax was within the acceptance range for bioequivalence.
