İlerlemiş Katı Tümörlü Hastalarda AZD8835'in Güvenliğini ve Farmakokinetiğini İnceleyen Faz I Doz Çalışması

Sade dilde özet

Bu çalışma, ilerlemiş katı tümörü (solid tumor) olan hastalarda AZD8835 adlı ilacın güvenliğini ve vücutta nasıl işlendiğini (farmakokinetiğini) tek başına ve fulvestrant ile birlikte değerlendirmektedir. Çalışmaya, ilerlemiş katı tümörü olan (ER pozitif, HER2 negatif meme kanseri (breast cancer) dahil, bir kısmında PIK3CA gen mutasyonu bulunan) ve genel durumu iyi (ECOG 0-1) yetişkinler katılabilmiştir. Çalışma Faz 1 aşamasında yürütülmüş ve tamamlanmıştır.

Kriterler ClinicalTrials.gov kaydından orijinal İngilizce haliyle alınmıştır. Uygunluk kararını yalnızca deneyi yürüten ekip verebilir.

Inclusion Criteria:

1. Part A: Histological or cytological confirmation of a solid tumor and disease progression. Part B: Histological or cytological confirmation of ER positive, HER2 negative breast cancer and disease progression or any other solid tumor with a PIK3CA gene mutation. Part C: Histological or cytological confirmation of ER positive, HER2 negative postmenopausal breast cancer with locally advanced or metastatic disease that is eligible for fulvestrant treatment. Part D: Histological or cytological confirmation of ER positive, HER2 negative postmenopausal breast cancer with locally advanced or metastatic disease that is eligible for fulvestrant treatment. Patients must also present with a tumor related mutation of the PIK3CA gene.
2. Availability of archival tumour tissue sample. If archival sample is not available, a fresh tumour biopsy must be provided.
