Vaccination of Metastatic Breast Cancer Patients With a CD80-modified Allogeneic Cancer Cell Line (KS2422) (KS2422-vacc)
Phase 1 Study: Induction of Systemic Immune Responses in Metastatic Breast Cancer Patients by Vaccination With a CD80-modified, Devitalized HLA-*A0201+ Breast Cancer Cell Line (KS24.22)
研究概览
详细说明
The trial was designed as an open label phase-I. Informed consent was given twice by the patients (1st for HLA-typing, 2nd for participation in the vaccination trial).
The first four vaccinations, which were given every two weeks, were followed by four monthly vaccinations. Additional vaccinations were permitted on request for patients who exhibited stable disease (SD).
Immediately before administration, KS24.22 cells were thawed and lethally irradiated. KS24.22 cells were adjusted to 10E7/ml in Ringer-Lactate-solution, transferred to 1 ml syringes and stored on ice until injected within a time frame of 2h. Vaccinations were given i.d. in the thigh with a total volume of 1 ml divided between two injection sites.
