Abstract
Description
도 1: 본 발명에 따른 방법의 구현예의 도식적 순서 및 핵심 데이터 . 비-페길화 출발 물질은 새로운 EPO 를 보충하지 않고 2 개의 추가 사이클에서 사용된다 . 2 개의 CEC 크로마토그래피 컬럼이 사용되는 WO 2009/010270 에 개시된 모노-페길화 EPO (Mircera®) 의 공지된 제조 공정에 비해 생산성이 증가되는 것으로 계산된다 . AEC 물질의 동적 결합 용량은 35 g/L (35 g 의 비-페길화 단백질 / L 수지) 이다 (WO 2009/010270 의 방법의 CEC 물질보다 30 배 더 높음) . HIC 컬럼은 동적 결합 용량 5 g/L (5 g 의 올리고-페길화 단백질 / L 수지) (WO 2009/010270 의 방법에서 사용된 CEC 물질보다 ~4 배 더 높음) 으로 통과 모드에서 로딩될 수 있다 . WO 2009/010270 에 개시된 방법과 비교하여, 제 1 컬럼은 더 작게 만들어질 수 있고, 3 사이클로부터 조합된 분획 (통과액) 은 동일한 크기의 제 2 컬럼에서 1 회 실행으로 처리될 수 있다.
도 2: 본 발명에 따른 방법의 구현예의 도식적 순서 및 핵심 데이터. 후속 사이클을 위해 반응된 EPO 를 동일한 양의 새로운 EPO 로 대체함으로써 배치 크기가 증가된다. 사이클 수는 여기에서 원하는 대로 달라질 수 있다. 여기서 배치 크기는 1 주일 내에 완료될 수 있도록 선택되었다. 계산된 생산성은 WO 2009/010270 에 개시된 모노-페길화 EPO 의 공지된 제조 방법에 비해 10 배 증가된다.
도 3: 본 발명에 따른 방법의 구현예의 도식적 순서 및 핵심 데이터. 페길화 반응에서 소비된 EPO 가 다음 사이클에서 동일한 양의 새로운 EPO 로 대체되기 때문에 배치 크기는 증가된다. 또한, 페길화 반응을 위한 EPO 의 농도는 10 g/L 로 증가되었다. 이러한 방식으로, 동일한 반응 부피에서 두 배의 양이 처리될 수 있다. 이 경우 사이클 수는 원하는 대로 달라질 수 있다. 여기서 배치 크기는 1 주일 내에 완료될 수 있도록 선택되었다. 생산성은 WO 2009/010270 에 개시된 모노-페길화 EPO 의 공지된 제조 방법에 비해 20 배 증가되는 것으로 계산된다.
도 4: 통과 모드에서 AEC 로부터의 샘플의 크로마토그램으로서, 통과 및 용리액 분획에서 페길화 반응 혼합물로부터 EPO 의 회수를 보여준다. 모노-페길화 EPO 및 올리고-페길화 EPO 는 통과액에 존재한다. EPO 는 단계 용리에 의해 거의 정량적으로 그리고 추가의 페길화 반응에 대하여 높은 순도로 회수될 수 있다. 분획의 조성은 RP-HPLC 에 의해 결정될 수 있다.
도 5: 3 개의 순차적 사이클에서 페길화 반응 혼합물로부터의 EPO 의 회수에 대한 AEC 크로마토그램 예. 사이클 2 및 3 에서 EPO 의 총량은 감소되는데, 이전의 사이클로부터 회수된 미반응 EPO 만 사이클 2 및 3 에서 페길화에 사용되었기 때문이다. 모노-페길화 및 올리고-페길화 EPO 는 통과액에 존재한다. 미반응 EPO 는 단계 용리에 의해 거의 정량적으로 그리고 추가의 페길화 반응에 대하여 높은 순도로 회수될 수 있다. 분획의 조성은 RP-HPLC 에 의해 결정되었다.
도 6: 결합 및 용리 모드에서 Toyopearl Phenyl 650 M 의 정제 성능에 대한 HIC 크로마토그램 예. 비-페길화 EPO 는 500 mM Na2SO4 의 통과액에서 제거되었다. 하강 Na2SO4 구배에서, 모노-페길화 EPO 는 약 300 mM Na2SO4 에서 양호한 분해능으로 올리고 종으로부터 용리된다. 분획의 조성은 RP-HPLC 에 의해 결정되었다.
도 7: 통과 모드에서 Toyopearl Phenyl 650 M 의 정제 성능에 대한 HIC 크로마토그램 예. 모노-페길화 EPO 는 약 300 mM Na2SO4 의 통과액에 존재한다. 올리고-페길화 EPO 종은 재생될 때까지 컬럼 상에 남아 있다. 분획의 조성은 RP-HPLC 에 의해 결정되었다.
도 8: 도 8A, 8B 및 8C 는 3 개의 순차적 사이클에서 페길화 반응 혼합물로부터의 EPO 의 회수에 대한 AEC 크로마토그램을 도시한다.
도 9: 결합 및 용리 모드에서 Toyopearl Phenyl 650 M 의 정제 성능에 대한 HIC 크로마토그램.
도 10: 통과 모드에서 Toyopearl Phenyl 650 M 의 정제 성능에 대한 HIC 크로마토그램.
