Cydectin TriclaMox

Current status:
European Commission final decision


Cydectin TriclaMox (5 mg/ml and 200 mg/ml) pour-on solution for cattle is a veterinary medicinal product containing 5 mg moxidectin per ml and 200 mg triclabendazole per millilitre. The product is administered topically on the back of the animal and is indicated for the treatment of mixed nematode and fluke infections in cattle.

The marketing-authorisation holder, Pfizer Animal Health, submitted an application for a type-II variation, in accordance with Article 16 of Commission Regulation (EC) 1234/2008, to add a new indication against lice species (Linognatus vituli, Bovicola bovis and Solenopotes capillatus) for Cydectin TriclaMox 5-mg/ml and 200-mg/ml pour-on solution for cattle. The reference Member State (RMS) was France and 12 concerned Member States (CMSs) were involved: Austria, Belgium, Denmark, Germany, Greece, Ireland, Italy, Luxembourg, Portugal, Slovenia, Spain and the United Kingdom.

The type-II-variation procedure (FR/V/0201/002/II/006) started on 16 May 2012. During the variation procedure, a potential serious risk to animal health was identified by Belgium, in particular the issue that the efficacy against the lice species had been insufficiently substantiated.

On day 90, major issues raised by the CMS Belgium remained unsolved. The procedure was thus referred to the Coordination Group for Mutual Recognition and Decentralised Procedures - Veterinary (CMDv) under Article 13(1) of Commission Regulation (EC) No 1234/2008 on 11 December 2012 by the RMS (France). The CMDv 60-day referral procedure was initiated on 14 January 2013. Day 60 of the CMDv procedure was on 14 March 2013, and since there was no agreement, the procedure was referred to the Committee for Medicinal Products for Veterinary Use (CVMP).

On 3 April 2013, France referred the matter to the CVMP under Article 13(2) of Commission Regulation (EC) No 1234/2008. The CVMP was requested to give its opinion on whether or not the data for the type-II-variation application supported the new indication against lice infestations.

The referral procedure started on 10 April 2013. The Committee appointed Dr B. Urbain as rapporteur and Dr M. Holzhauser-Alberti as corapporteur. Written explanations were provided by the marketing-authorisation holder on 20 May 2013.

Based on the evaluation of the available data, the CVMP adopted, on 16 July 2013, an opinion recommending the granting of the variation to the marketing authorisations for Cydectin TriclaMox (5 mg/ml and 200 mg/ml) pour-on solution for cattle. The CVMP concluded that satisfactory efficacy towards Linognatus vituli, Bovicola bovis and Solenopotes capillatus could be expected in the field.

The list of product names concerned is given in annex I. The scientific conclusions are provided in annex II together with the amendments of the relevant sections of the summary of product characteristics, labelling and package leaflet in annex III.

The final opinion was converted into a decision by the European Commission on 25 September 2013.
