Abstract
Description
도 1은 2주 동안 하루 여섯 방울씩 투약된 후, 8주 기간에 걸쳐 광 간섭 단층촬영 (OCT-CFT)을 이용하여 개선된 중심와 두께 측정치를 갖는 리포좀 라니비주맙 제제로 치료된 단일 환자로부터 얻은 데이터를 보여준다. 8주에 환자는 CFT에서의 증가를 나타내었고 치료는 하루 두 방울의 일일 용량으로 10주에 다시 시작되었다. 도 1은 12주 내지 14주 기간에 다시 발생하는 CFT에서의 개선을 보여준다.
도 2는 2주 동안 하루 여섯 방울씩 투약된 후, 8주 기간에 걸쳐 개선된 시력 측정치 (ETDRS BCVA)를 가진, 리포좀 라니비주맙으로 치료된 동일한 임상 환자를 보여준다. 8주에 환자는 VA에서의 감소를 나타내었고 치료는 하루 두 방울의 일일 용량으로 10주에 다시 시작되었다. 도 2는 12주 내지 14주 기간에 다시 발생하는 VA에서의 개선을 보여준다.
도 3은 다중라멜라 리포좀 및 단일라멜라 리포좀의 현미경 관찰 사진을 보여준다.
도 4는 시간에 따른, 라니비주맙의 리포좀 제제로 치료된 환자의 중심와 두께의 OCT 결과를 보여준다.
도 5는 시간에 따른, 환자의 대측성 눈의 중심와 두께의 OCT 결과를 보여준다.
도 6은 3명의 환자에서 눈 연구를 위해 시간에 따른 BCVA의 결과를 보여준다.
도 7은 대측성 눈에 대해 시간에 따른 BCVA의 결과를 보여준다.
