Association of rash with outcomes in a randomized phase II trial evaluating cetuximab in combination with mitoxantrone plus prednisone after docetaxel for metastatic castration-resistant prostate cancer . cetuximab (C), a chimeric monoclonal antibody that binds epidermal growth factor receptor (EGFR), is active against androgen-independent prostate cancer cell lines and might enhance the activity of chemotherapy. The efficacy of combining cetuximab with mitoxantrone (M) plus prednisone (MP) was evaluated in progressive metastatic castrate-resistant prostate cancer (CRPC) after receiving docetaxel. ### Materials And Methods Patients with progression after receiving docetaxel were eligible and randomized 2:1 to CMP or MP. Therapy was mitoxantrone 12 mg/m(2) intravenously (I.V.) on day 1, oral prednisone 10 mg daily in both arms, and cetuximab 250 mg/m(2) I.V. (400 mg/m(2) day 1, cycle 1) on days 1, 8, and 15 in the CMP arm. Cycles were repeated every 21 days. Radiologic assessments of disease and PSA (prostate-specific antigen) occurred every 4 cycles. The primary endpoint was time to progression (TTP). ### results A total of 115 patients were enrolled, 75 in the CMP and 40 in the MP arm: the median TTP was 4.9 and 6.6 months, respectively; the measurable disease response rate was 2% and 4%, the PSA response rate 7.7% and 17.6%, and median survival 11.9 and 15.7 months, respectively. Key grade 3-4 toxicities were neutropenia 44% and 25.6%, anemia 6.7% and 7.7%, thrombocytopenia 6.7% and 2.6%, and fatigue 8% in both arms. In an unplanned exploratory analysis, median TTP with (n = 24) and without rash (n = 51) in the CMP arm was 10.3 months vs. 2.8 months (P = .004). On multivariable analysis,rash was significantly associated with TTP (hazard ratio [HR] = 0.43; P = .01). ### conclusions The treatment with CMP is not recommended in unselected men with docetaxel-treated CRPC, although rash might help develop tailored therapy.
