Dear All, As per EMA GL on MR products, for the Steady state studies of MR products under fed condition, the meal to be given prior to dosing is mentioned as "standard Meal", while in single dose fed studies it is stated as high fat meal. So how should standard meal be around total of 700-800 kcal meal!! Please provide your views on the same Regards, Jay |

Shouldn't it be the same meal as in the single dose fed study? I recall when I did SS fed study for FDA, the meal was high fat breakfast. I don't think EMA would use different meals. John |

Hi John, ❝ Shouldn't it be the same meal as in the single dose fed study? Nope. Jay understood the GL correctly (Section 6.1.1.2): […] steady-state studies should be performed under the conditions concerning concomitant food intake recommended in the SmPC for the originator product. If the SmPC states that the product has to be taken in fed condition only the study should be performed in fed conditions (standard meal) including the day of profiling. If the SmPC states that the product should be taken in fasted state or irrespective of food intake the studies should be performed in fasted conditions. Fasting conditions in a multiple dose study needs to be adapted to realistic situations, i.e. morning administration requires a 10 hour fasting interval whereas for all other administrations 4 hour fasting prior to administration is sufficient. Fasting after each administration should be defined as 2 hour minimum. ❝ I recall when I did SS fed study for FDA, the meal was high fat breakfast. FDA ≠ EMA. ❝ I don't think EMA would use different meals. Cough… At conferences (Barcelona 2011, Bonn 2013) we had lengthy discussions about this issue. If I recall it correctly, a vast majority of attendees followed these arguments:
Bonus question: Design a multiple dose fed state study of a delayed release product administered thrice a day – compliant with EMA’s last two sentences quoted above. — Dif-tor heh smusma 🖖🏼 Довге життя Україна!

Dear Helmut, ❝ • A compromise would be normal meals during saturation phases and the same (high-fat) meal like in the single dose study on profile days.[/list]Why EMA decided to suggest normal meals throughout the entire study remains a mystery. We are all waiting since last November for the PKWP’s comments to be published. Promised for “the next week” a couple of times (Amsterdam March, London April, Budapest May)… I am going through EMA's website and searching for comments on GL for modified release dosage form. But could not get it. Whether they published comments or not? Have you received it? Presently, I am designing fed MD study for a prolonged release formulation. Should I go for normo-caloric meals (rather than high fat meal) throughout the study including profiling day. This will comply with present GL, right? Thank you very much in advance. MMW |
