Clinical Trial Results:
A phase III, two-armed, randomised, double blind, parallel study to compare the efficacy and safety in high CHD-risk patients with mixed dyslipidaemia of a 12-week administration of a fixed dose combination of Fenofibrate 160 mg and Pravastatin 40 mg (PRAVAFENIX®) versus Atorvastatin 20 mg.

The purpose of the protocol version 2.0 was to notify a change concerning the secondary packaging for the run-in treatment. In fact the run-in treatments were packaged in bottles and not in boxes as mentioned in the protocol version 1.0. |

Further to the comments from the Latvian authorities, the protocol and the ICF have been adapted to exclude the oral anticoagulants from the permitted therapies.
Oral anticoagulants should be titrated down when initiating treatment with the test treatment PRAVAFENIX® due to potential interaction with fenofibrate. The risk of interactions existed with vitamin K antagonists i.e. oral anticoagulants, namely warfarin, acenocoumarol and phenprocoumone.
Titration of the anticoagulant was not feasible in the study as the study medication was blinded during the efficacy phase and statin (the other arm) did not require anticoagulant down titration.
To avoid the appearance of any safety issue, it was preferred to non include patients taking oral anticoagulants.

The sponsor encountered a significant problem to buy the sufficient quantity of AtorstatinEG® (comparator) with an adequate expiry date needed for the replacement of current treatment at sites (scheduled for October 2013). The expiry date of available batches (Mid 2014) did not allow sufficient flexibility in patient recruitment. Therefore the sponsor decided to change the comparator from AtorstatinEG® to Totalip®.
The molecule remained the same “Atorvastatin” but the commercial name was different. Totalip® and AtorstatinEG® were generic drugs of the originator Lipitor®. All these tablets were immediate release film-coated tablets with Atorvastatin Calcium salt as Active Ingredient.
Posology and route of administration (oral administration, once a day, with or without food) were identical for all the drug formulations.
For the run-in phase of the trial the sponsor used tablets of Totalip® 10mg instead of tablets of AtorstatinEG® 10mg but for the efficacy phase of the trial the sponsor used also tablets of Totalip® 10 mg (the blinded capsule will contain 2 tablets of 10mg). Tablet of Totalip® 20 mg cannot be used due to the high size of the tablet.
Blinding was not affected by using two 10 mg tablets as the capsules were also filled with microcrystalline cellulose. In-vitro dissolution profiles of blinded capsules (containing either 1 tablet of AtorstatinEG® 20mg or 2 tablets of Totalip® 10 mg) compared to the unblinded tablets were identical.
