First clinical experiences with abiraterone and cabazitaxel for the treatment of metastatic castration-resistant prostate cancer patients following docetaxel chemotherapy are reported.
We describe PSA response rates and disease control rates determined by imaging studies at 3 months as well as side effects in the daily routine. All patients were treated within the"compassionate use" programs of cabazitaxel and abiraterone or treated according to their inclusion and exclusion criteria at the "Technische Universitat Munchen".
Of 54 patients, 15 were treated with cabazitaxel and 39 with abiraterone. In patients treated with cabazitaxel, after 3 months of therapy the PSA reduction rate > 50% was 46.2%, the PSA progression rate was 15.4%, and the disease control rate was 83.3%. Main grade 3/4 hematotoxicities were neutropenia (40%) and anemia (20%). Febrile neutropenia was observed in 2 of 15 (13.3%) patients. Main non-hematological grade 3/4 toxicities were diarrhea (13.3%) and polyneuropathy (13.3%). In patients treated with abiraterone, after 3 months of therapy the PSA reduction rate > 50% was 35.1%, the PSA progression rate was 46.0%, and the disease control rate was 47.1%. Main grade 3/4 hematotoxicities were anemia (5.1%) and thrombocytopenia (5.1%). Main non-hematological toxicities were fatigue (20.5%), sweating (17.9%), and constipation (10.3%).
Utilization of cabazitaxel and abiraterone in the daily routine show response rates comparable to their approval studies with acceptable side effects.
