GOG-9929 A Phase I Trial of Sequential Ipilimumab After Chemoradiation for the Primary Treatment of Patients with Locally Advanced Cervical Cancer Stages IB2/IIA with Positive Para-Aortic Lymph Nodes Only and Stage IIB/IIIB/IVA with Positive Lymp Nodes


Background:Historically, the treatment of invasive cervical cancer was limited to either surgery or radiotherapy. The addition of systemic chemotherapy to radiation therapy for the treatment of cervical cancer has revolutionized the management and clinical outcome of these patients. The discovery of tumor-associated antigens (TAAs) on tumors and host immune responses to these antigens has been heralded as a promising targeted immunotherapeutic strategy. Ipilimumab affects tumor cells indirectly, and measurable clinical effects emerge after the immunological effects.Objectives:To estimate the maximum tolerated dose (MTD) and dose-limiting toxicities(DLT) of adjuvant ipilimumab following concurrent weekly cisplatin and extended field radiation in women with newly diagnosed locally advanced cervical cancer Stage IB2/ IIA with-positive para-aortic lymph nodes only and Stage IIB/ IIIB/ IVA with positive lymph nodes. To examine progression free survival for 1 year after study completion.Primary Endpoints: DLTs occurring in the first two cycles of adjuvant ipilimumab (as defined in Section 5.3) in the dose escalation phaseDLTs occurring in the four cycles of adjuvant ipilimumab in the feasibility phaseToxicities as assessed by CTCAE Version 4Description of Study Arms:Concurrent Weekly Cisplatin 40mg/m2/week (max dose 70 mg) and Extended Field Radiation: pelvis + para-aortics4500 cGy in 25 fractions to the para-aortic nodes (180 cGy/fraction)4500 cGy in 25 fractions to the pelvis (180 cGy/fraction)Intracavitary BrachytherapyLDR 4000cGy OR HDR 3000cGyAdjuvant Immunotherapy: Dose Escalation SchemaDose Level Ipilimumab Rx Schedule1 (Starting Dose) 3 mg/kg q3 weeks x 4*2 10 mg/kg q3 weeks x 4*1a 6 mg/kg q3 weeks x 4*Follow-up:Participants will be followed every 3 months for 1 more year.Statistics/Analysis:Patient entry will be accomplished via the GOG Statistical and Data Centers Phase I reservation and registration systems. This study will evaluate the MTD and feasibility of the study regimens by assessing the tolerability through dose limiting toxicities.



Inclusion and Exclusion Criteria

  • Bilirubin =< 1.5 x ULN
  • Serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN
  • Alkaline phosphatase =< 2.5 x ULN
  • Neuropathy (sensory and motor) =< grade 1
  • Patients with ureteral obstruction (i.e., hydronephrosis identified on CT imaging) must undergo stent or nephrostomy tube placement prior to study entry
  • Patients must meet the pre-entry requirements specified
  • Patients must have signed an approved informed consent and authorization permitting the release of personal health information
  • Patients of child-bearing potential must have a negative serum pregnancy test prior to study entry (within 72 hours prior to initiation of study treatment) and be practicing an effective form of contraception; women should not breast-feed while on this study
  • Patients must not be receiving any other investigational agent
  • Patients should have an audiogram at baseline, and patients with pre-existing hearing loss or hearing loss during treatment should be assessed frequently during cisplatin therapy

  • Patients who have received previous pelvic or abdominal radiation, cytotoxic chemotherapy, or previous therapy of any kind for this malignancy or any pelvic or abdominal radiation for any prior malignancy
  • Patients with active infection
  • Patients who have circumstances that will not permit completion of this study or the required follow-up
  • Patients with renal abnormalities, such as pelvic kidney, horseshoe kidney, or renal transplantation, that would require modification of radiation fields
  • Patients with a history of other invasive malignancies, with the exception of non-melanoma skin cancer, are excluded if there is any evidence of other malignancy being present within the last five years; patients are also excluded if their previous cancer treatment prevents full delivery of this protocol therapy
  • Patients who have undergone major surgery, excluding diagnostic biopsy, within 30 days (to allow for full recovery) prior to registration
  • Patients who have a significant history of cardiac disease, i.e., uncontrolled hypertension, unstable angina, congestive heart failure, or uncontrolled arrhythmias within 6 months of registration
  • Patients with a history of prior treatment with ipilimumab, anti-programmed cell death (PD) 1 antibody, cluster of differentiation (CD)137 agonist or other immune activating therapy such as anti-CD 40 antibody
  • Patients who are receiving any other investigational agents
  • Autoimmune disease: patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's disease, are excluded from this study, as are patients with a history of symptomatic disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g., Wegener's Granulomatosis]); central nervous system (CNS) or motor neuropathy considered of autoimmune origin (e.g. Guillain-Barre syndrome and myasthenia gravis, multiple sclerosis)
  • Patients with known immune impairment who may be unable to respond to anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA 4) antibody
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition ipilimumab or other agents used in study
  • Patients with chronic human immunodeficiency virus (HIV), hepatitis B or hepatitis C infections should be excluded
