Abstract
Description
도 1은 72 시간 젬시타빈 노출 후 세포독성을 도시한다. 세포주 TFK-1 (A) 및 EGI-1 (B)의 생존력은 실시예 1에서 물질 및 방법 하에 기재된 바와 같이 72 시간 젬시타빈 인큐베이션 후 MTT 검정에 의해 분석되었다. 각각의 데이터 포인트는 3 실험으로부터 평균 (+/- 표준 편차)를 나타낸다.
도 2는 TFK-1 세포주에서 100 nM 젬시타빈을 가진 PCI를 도시한다. 실험은 실시예 1에서 물질 및 방법 하에 기재된 바와 같이 100 nM의 젬시타빈 용량으로 수행되었다. 데이터 포인트는 3 평행한 측정 (+/- 표준 편차)의 평균 값이고 3 독립적인 실험의 하나의 대표를 나타낸다. 도에서 PDT는 "PCI 단독"을 의미한다.
도 3은 EGI-1 세포주에서 100 nM 젬시타빈을 가진 PCI를 도시한다. 실험은 실시예 1에서 물질 및 방법 하에 기재된 바와 같이 100 nM의 젬시타빈 용량으로 수행되었다. 데이터 포인트는 3 평행한 측정 (+/- 표준 편차)의 평균 값이고 3 독립적인 실험의 하나의 대표를 나타낸다. 도에서 PDT는 "PCI 단독"을 의미한다.
도 4는 젬시타빈의 상이한 용량으로 PCI 치료 후 TFK-1 세포의 콜로니 형성 능력을 도시한다. 실험은 (도에서 명시된) 젬시타빈의 상이한 용량 그리고 140 초의 조명 시간으로 실시예 1에서 물질 및 방법 하에 기재된 바와 같이 수행되었다. 3 독립적인 실험은 본질적으로 유사한 결과로 수행되었다.
도 5는 200 mg/kg 젬시타빈을 가진 PCI의 효과에 관한 동물 연구의 결과를 도시한다. 피하로 성장하는 NCI-H460 인간 폐 암 종양 세포를 가진 동물은 정맥내 주사로 5 mg/kg Amphinex® (TPCS2a) 투여되었다. 3 일 후 동물은 200 mg/kg의 젬시타빈 투여되었고, 종양은 4 시간 후 조명되었다. 종양의 크기는 주당 2-3 회 측정되었다. 결과는 광화학적 치료 단독 (PCI 단독)도 젬시타빈 단독도 미처리된 종양을 가진 대조군 그룹 (미처리)에 비교된 경우 종양 성장에서 상당한 효과를 갖지 않았다는 것을 보여준다. 그에 반해서, PCI 및 젬시타빈의 조합은 종양 성장을 실질적으로 감소시켜서 PCI가 젬시타빈의 효과를 상당히 향상시킬 수 있다는 것을 나타냈다.
도 6은 400 mg/kg 젬시타빈을 가진 PCI의 효과에 관한 동물 연구의 결과를 도시한다. 방법은 도 5에 대하여 상기 기재된 바와 같이 수행되었고 단, 400 mg/kg의 젬시타빈이 사용되었다. 결과는 광화학적 치료 단독 (PCI 단독)도 젬시타빈 단독 (젬시타빈 400 mg/kg)도 미처리된 종양을 가진 대조군 그룹 (미처리)에 비교된 경우 종양 성장에서 상당한 효과를 갖지 않았다는 것을 보여준다. 그에 반해서, PCI 및 젬시타빈의 조합은 종양 성장을 실질적으로 감소시켜, PCI가 젬시타빈의 효과를 상당히 향상시킬 수 있다는 것을 나타냈다.
도 7은 6 개월에서 치료에 양성 반응을 나타냈던 환자, 즉 부분적인 반응 (PR) 또는 완전한 반응 (CR)을 가진 자의 퍼센트를 도시한다. 환자는 표준 비-PCI 화학요법 치료 (ABC02)로 처리된 것에 비교된 PCI 치료 (PCI 병기 1 : 집단 3 및 4)를 거쳤다.
도 8은 PCI 치료 후 모든 표적 (측정가능한) 병변의 합계의 상태의 관점에서 집단 3 및 4 담관암 환자의 반응을 도시한다.
도 9는 PCI 치료 후 기대된 처리 표적 (측정가능한) 병변의 상태의 관점에서 집단 3 및 4 담관암 환자의 반응을 도시한다.
도 10은 모든 집단으로부터 모든 방사선학적으로 평가가능한 담관암 환자에서 전체적인 표적 종양 크기 감소를 도시한다.
