  12. To determine if combining Cetuximab with cisplatin during radiation therapy increases overall survival (OS) when compared with weekly cisplatin and radiation therapy in patients with cervical cancer metastatic to high common and/or para-aortic lymph nodes. • Secondary Objective • To determine if the addition of Cetuximab to cisplatin and radiation therapy in this patient population improves progression-free survival (PFS). • To determine the relative toxicities of the addition of Cetuximab to cisplatin in this patient population. CVM0503

  13. Test the hypothesis that Cetuximab will be more effective in tumors that express low compared with high levels of the hypoxia marker Hypoxia Inducible Factor-1α (HIF-1α) and epidermal growth factor receptor (EGFR), CVM0503

  14. Concurrent Weekly Cisplatin + Cetuximab (preferably Monday) • Cisplatin 30mg/m2/week x 6 weeks • Cetuximab 400 mg/m2 initial loading dose week 1, then 250 mg/m2 x 5 weeks • VERSUS • Cisplatin 30mg/m2/week x 6 weeks • In patients receiving extended field radiation therapy; pelvis and para-aortics. • 4500 cGy in 29 fractions to the para-aortic nodes • (150 cGy/fraction) • 4500 cGy in 25 fractions to the pelvis • (180 cGy/fraction) CVM0503

  15. Trial population • Cervical cancer patients with positive para-aortic and/or pelvic nodes : • Squamous Cell Carcinoma, Adenocarcinoma, Adenosquamous Carcinoma, • Clinical stages • IB, IIA, IIB, IIIA, IIIB, IV • Number of subjects: 328 CVM0503

GOG-0233/ACRIN-6671 UTILITY OF PREOPERATIVE FDG-PET/CT AND FERUMOXTRAN-10 MRI SCANNING PRIOR TO PRIMARY CHEMORADIATION THERAPY TO DETECT RETROPERITONEAL LYMPH NODE METASTASIS IN PATIENTS WITH LOCOREGIONALLY ADVANCED (IB2, IIA 4 CM, IIB-IVA) CARCINOMA OF THE CERVIX. Has accrued 22/325 patients

  18. GOG 219 ACCRUAL TO DATE = 301 PATIENTS Enrollment primarily from U.S. sites International participation increasing, specifically NCI Canada Factors (pro) Starting dose reduced after 1st toxicity evaluation NCIC sites gaining experience with regimen Factors (con) Regulatory bodies in other countries International shipment of drug GOG-0219

  19. ENROLLMENT BY QUARTER GOG-0219

  20. AMENDMENT The Data Monitoring Committee (DMC) of the Gynecologic Oncology Group convened to review the interim safety analysis as outlined in section 11.5 of the study. In reviewing toxicity data, there was a higher than 20% incidence of Grade 3 or 4 toxicity in the form of leucopenia and metabolic toxicity. Median length of radiation therapy was similar in both arms and there were no deaths related to study participation. Based on their review in assessing the clinical impact of the toxicity, the DMC recommended decreasing the starting dose on regimen II to by one dose level rather than two dose levels as originally stipulated in section 11.5. The starting dose on trial (now dose level I) is the previous dose level -1 from former versions (prior to NCI Version Date 10/03/2007). GOG-0219

  21. AMENDMENT Regimen II: Concurrent Cisplatin and TPZ and Radiation Therapy (10/23/2007) Cisplatin 60mg/m2 (max = 105 mg) administered IV over 30-60 minutes days 1, 15 and 29 with radiation therapy TPZ 220mg/m2 (max = 385 mg) IV administered over two hours prior to Cisplatin on days 1, 15 and 29 TPZ 220mg/m2 (max = 385 mg) IV over two hours days 8, 10, 12, 22, 24, 26 with radiation therapy. GOG-0219

  22. AMENDMENT A second safety analysis will be performed after treating 30 more patients on the TPZ arm (with the new starting dose). In the event Grade 3 or 4 toxicity continues to be significantly higher among patients on the TPZ arm or duration of radiotherapy is prolonged significantly in any of the arms, the trial committee may recommend further dose modification or study termination.

  41. Hypothesis To determine if adjuvant systemic chemotherapy following chemoradiation therapy will improve disease-free and overall survival compared to chemoradiation therapy alone in patients with high-risk early-stage cervical carcinoma found to have positive nodes and/or positive margins and/or positive parametria after a radical hysterectomy. The expected benefit would be approximately 10%-15% – Acrrual - 400 patients. RTOG-0724

  42. Endpoints 2.1 Primary objective: Disease-free survival 2.2 Secondary objective(s): 1) Toxicity 2) Overall survival 3) Quality of life 4) To collect fixed tissue to identify tumor molecular signatures that may be associated with patient outcomes. 5) To collect blood from serum and plasma - looking factors correlated with toxicity and outcome RTOG-0724
