Study of Nimotuzumab, Radiation Therapy and Cisplatin Versus Radiation Therapy and Cisplatin for Treatment of Stage IB e IVA UCC(CORUS)

The primary study objective will be to assess the efficacy of the combination of radiation therapy with nimotuzumab and cisplatin, as compared to the combination of radiation therapy plus cisplatin in the treatment of Uterine Cervical Carcinoma (UCC).

The secondary study objectives will be safety and tolerability evaluations, to determine treatment feasibility and the interim efficacy evaluation according to other parameters routinely used in oncology.

This will be a phase II, randomized, controlled, open-label, multicenter, and two-arm study. The study will be conducted in Brazil and has the purpose of determining the activity and safety of nimotuzumab in terms of overall and distant disease-free survival, radiological and clinical gynecological examinations, as well as by biopsy, if indicated, progression-free survival, local control of long-term disease, frequency of treatment-emergent adverse events, frequency of severe treatment-emergent adverse events.

All participating patients will sign a consent form before they undergo any study-related procedure.The eligible patients will have stage IB and IVA uterine cervical carcinoma and they will be randomized to one of two treatment groups.

Randomization and treatment assignment will be performed by a company specifically contracted for such purpose and will be per research site and disease stage (IB2 to IIIA versus IIIB to IVA), 1:1.

Eligibility Criteria:
Inclusion Criteria:

* Signed informed consent form.

Exclusion Criteria:

* Para-aortic lymph nodes involvement through radiological and/or surgical staging, at investigator's discretion;
* Current severe comorbidity that, in the investigator's opinion, would put the patient at a significantly higher risk or will jeopardize protocol compliance;
* Current bowel inflammatory disease;
* Current major neurological or psychiatric disease, including clinically significant dementia and seizures, at the investigator's discretion;
