Cells for HPV analysis wasn't available on most Cilengitide patients, but one of the oropharynx patients who were screened, 75% were p16 positive. Colleagues and Burtness completed the first clinical trial examining the role of cetuximab in the first line treatment of terminal advanced SCCHN. An overall total of 117 patients who'd not received prior chemotherapy for chronic andor metastatic disease were randomized to either cisplatin with placebo or to cisplatin with cetuximab. There was a statistically significant improvement in response rate from 10% to 26% with the addition of cetuximab with a trend towards an improvement in overall survival from 8 to 9. 2 weeks. However, Cholangiocarcinoma the variation in survival wasn't statistically significant, probably due to insufficient power, in addition to research design that helped cross-over to cetuximab if patients had developed about the placebo arm. In a much bigger phase III research PR-619 generally known as the EXCESSIVE test, 442 people with advanced SCCHN who had not received previous treatment for recurrentmetastatic disease were randomized to either a platinum containing doublet or a related doublet with cetuximab. The chemotherapy regimen used was platinum in combination with 5 fluorouracil. Patients randomized to receive cetuximab with chemotherapy can continue to receive maintenance cetuximab until development. Cross to cetuximab for anyone patients originally randomized to chemotherapy alone was not allowed. The addition of cetuximab demonstrated a statistically significant improvement in survival from 7. 4 to 10. 1 months. These data established the position of cetuximab in first line treatment for advanced SCCHN. Several studies have established the experience of cetuximab among patients with platinum refractory disease. In a phase II trial, 96 patients with platinum refractory disease were treated by adding cetuximab for the platinum dose and schedule that the patients had previously failed. The reaction rate was 10%, having a disease control rate of 53%, median time and energy to progression of 2. 79 weeks and overall survival of 6. 01 months. In a similar phase II study, 130 patients with stable disease or progressive disease on past platinum therapy, received treatment with cetuximab and cisplatin. There were two PD cohorts, PD1, which had patients whose disease progressed on two series of process chosen platinum based therapy and PD2, which had patients whose disease progressed within three months of any platinum based therapy. The reaction rates were 18% for the SD cohort, 20% for the PD1 cohort and 6% for the PD2 cohort with median survivals of 11. 7 months, 6. 1 months and 4. 3 weeks respectively. A third phase-ii study enrolled 103 people definitely failing platinum-based treatments and treated them with cetuximab as a monotherapy. They reported a response rate of 12. 6%, median overall survival of 5 and disease control rate of 46%. eighty-four months.
