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 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

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


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 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 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.

Anuja Jhingran RTOG-0724

36 Background 90% early stage cured with surgery or xrt alone
15%-20% of early stage present with positive nodes, parametrium or margins - survival drops to 50-70% with surgery alone Even with adjuvant xrt - 40% fail - 10% in field and 10% out of field Recent update of the SWOG trial – 5-yr survival with CT/RT – 2 or more positive nodes – 77% RTOG-0724

44 New Concepts in Locally Advanced Cervix Cancer
Nick Reed Personal thoughts for debate at GCIG Nov 2008

45 Need for Improvement Improving outcomes of bulky locally advanced cervix cancer New Approaches Induction / neoadjuvant schedules Maintenance treatments Targeted agents Functional Imaging

46 Diagnostic Pathway CCRT Newly diagnosed Stage 1B2 – 4A
Baseline Imaging NACT Induction Reassessment Imaging and CCRT CCRT

47 So where is my evidence?

48 Newer Approaches - Induction
Meta-analysis from data with Cis +/- Carboplatin vs Cisplatin Addition of Paclitaxel - Hoskin & Glynne-Jones Mexico- Duenas -Gonzalez UCL – McCormack CX2 study Still premature but exciting interest


50 The Study Options Maintenance chemotherapy NACT Induction CCRT

51 Reed’s Observations I am convinced NACT is the way forward
I am convinced dose dense and dose intense schedules are needed I think a taxane  is essential rather than platinum alone I think TR and  functional imaging should  be  integral

52 So what would I propose?? Fresh tissue for banking +/- serum
Baseline  scan , preferably PET CT +/- MRI (advice from  radiologists) Explore new imaging agents (hypoxia markers) 9 weekly doses  of  carbo/paclitaxel  (AUC 2-3 and  pac mg/m2)  Reassess clinically and  radiologically plus repeat samples for  freezing

53 Diagnostic Pathway CCRT TR Biopsy Imaging TR Biopsy Imaging
Newly diagnosed Stage 1B2 – 4A Baseline Imaging NACT Induction Reassessment Imaging and CCRT CCRT TR Biopsy Imaging TR Biopsy Imaging

54 Chemo-Rads CCRT Proceed to standard  concomitant chemoradiotherapy (CCRT) Try for international consensus on EBRT dose and also BT

55 The Other Option - Maintenance
Why? Tierney IPA suggests benefit Which maintenance? How many cycles Conventional or TAT or both Candidates

56 The Next Steps Next phase would  be to consider adding a  biological/TAT, maybe  RCT phase 2 Next phase would  be to look at maintenance or no  maintenance

57 The Study Options Maintenance chemotherapy NACT Induction CCRT

58 Where next? Discussion Manchester SOTS??

59 A pilot study of adjuvant chemotherapy for high-risk cervical cancer
Linda Mileshkin, Danny Rischin, Kailash Narayan ANZGOG 59

60 Background Early-stage cervical cancer is highly curable with surgical approaches or chemoXRT Lower cure rates with more advanced disease seen in those who have not participated in screening Traditional main prognostic factor is the FIGO staging system - principally based on clinical examination Uterine and nodal involvement on imaging also prognostic ANZGOG 60

61 Background Prospective audit data from 238 pts treated with primary chemoXRT for cervical cancer 170 (71%) had corpus invasion on MRI 41% of these recurred cf. 19% without invasion FIGO stage and clinical diameter not prognostic in the presence of uterine invasion 108 (45%) had PET +ve nodal disease 51% PET +ve recurred cf. 22% in PET -ve Majority of recurrences distant ANZGOG Narayan K 2006 and 2007 61

62 Background – adjuvant chemo
Chemo concurrent with XRT improves survival and is standard care Additional chemo after chemoXRT may treat distant mets and ↑ survival in high-risk pts Few small retrospective studies with older chemo in unselected patients suggest no survival advantage and some toxicity Carboplatin/paclitaxel active in cervical ca and likely more deliverable after XRT than cisplatin/topotecan ANZGOG 62

63 Background – adjuvant chemo
GOG 109: post-op chemoXRT for those with +ve nodes/ margins or parametrium involved :2 extra cycles of cis/5FU given after chemoXRT : subset analysis suggested improved PFS and OS with more cycles of chemo ANZGOG 63

64 Research Plan Design: Single-arm phase II study (n=30:pragmatic)
Eligibility: Stage 1b-IVa cervical cancer suitable for primary treatment with chemoradiation with curative intent in addition to one of the high-risk features of: Pelvic nodal involvement on: staging PET scan staging CT if >15mm diameter, or - frozen section during planned surgery leading to abandonment of planned hysterectomy b) Uterine involvement on MRI EBR alone; EBR plus brachytherapy; EBR plus Chemo ANZGOG

65 Aims and Objectives Aim: To test the feasibility of the regimen
Primary objective: To determine the percentage of patients able to complete all treatment components without significant treatment interruptions or omissions due to grade 3 or 4 toxicity Secondary objectives: To determine the Acute and long-term toxicities Patterns of disease recurrence Failure-free survival ANZGOG 65

66 Intervention Gy of external beam XRT in 25 to 28 fractions plus brachytherapy Cisplatin 40mg/m2 weekly during XRT Within 4 weeks of completion of XRT and following recovery from toxicities, 4 cycles of 3 weekly adjuvant chemotherapy using Carboplatin AUC 5 and Paclitaxel 175 mg/m2 ANZGOG 66

67 Future phase III study Stage Ib-IVa Cervical cancer Node positive and/or Uterine invasion 4 cycles Carboplatin + Paclitaxel Standard chemoXRT Standard chemoXRT ANZGOG 67

68 GCIG Consensus: Cervical Brachytherapy
Produce a document that can be used as a template for upcoming GCIG trials that contains “acceptable” evidence based brachytherapy dosing. Akila Viswanathan has agreed to head the project. Plan to work via and possibly conference call(s) with goal of finalizing the manuscript by the cervical SOTS meeting in 2009.
