Previously untreated patients were randomly assigned to either FOLFOX4 administered every 2 weeks until progression (arm A) or FOLFOX7 for 6 cycles, maintenance without oxaliplatin for 12 cycles, and reintroduction of FOLFOX7 for another 6 cycles (arm B). Data showed that there was no significant difference in median progression-free survival (PFS) and overall survival (OS) between two arms. Furthermore, this study showed lower Grade 3 neurotoxicity rate in arm B (17.9% vs 13.3%, P = 0.12).In order to investigate the efficacy and feasibility of the novel "Stop and go" strategy in Chinese mCRC patients, Prof. Shu Yongqian in JiangShu Province Hospital plans to conduct a randomized controlled study to compare continuous FOLFOX4 vs. FOLFOX4 in a Stop-and-Go Fashion in 1st Line mCRC patients. To avoid the high oxaliplatin dosage related neurotoxicity, FOLFOX4 regimen is chosen in this study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with histologically confirmed adenocarcinoma of the colon or rectum\n* Unresectable metastases\n* At least one bidimensionally measurable lesion of ≥ 1 cm\n* No previous chemotherapy for metastatic disease; Completed at least more than 1 year oxaliplatin therapy for adjuvant treatment\n* 18-75 years old\n* ECOG 0-2\n* Life expectancy greater than 3 months\n* Hemogram: WBC≥4.0 X109/L, ANC ≥2 X109/L, PLT ≥100 X109/L, Hb ≥90g/L,\n* Adequate Renal Function\n* Adequate Liver Function\n* Signed informed consent before the treatment\n\nExclusion Criteria:\n\n* Patients with previous oxaliplatin based adjuvant chemotherapy within 1 Year\n* Completely or partially bowel obstruction\n* Presence of peripheral neuropathy (CTC\\>grade I)\n* Severe mental disorder\n* CNS metastasis\n* With other severe disease: uncontrolled active infectious disease, uncontrolled hypertension, heart infarction within 1 year, uncontrolled high-risk arrhythmia, unstable angina\n* With other malignant disease previously or concurrently\n* Receive other anti-tumor treatment\n* Pregnant or lactating women, or women of child bearing potential without contraceptive method.'}, 'identificationModule': {'nctId': 'NCT01023633', 'briefTitle': 'OPTIMOX1 in Chinese mCRC Patients', 'organization': {'class': 'OTHER', 'fullName': 'Nanjing Medical University'}, 'officialTitle': 'A Randomized Study Of Continuous FOLFOX4 vs. FOLFOX4 in a Stop-and-Go Fashion in 1st Line Advanced Colorectal Cancer', 'orgStudyIdInfo': {'id': 'Oxali04882'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Arm A: FOLFOX 4 continuous (Oxaliplatin, LV, 5-FU)', 'description': 'The arm A (FOLFOX4 continuous arm):receive FOLFOX4 every 2 weeks until progression or for maximum 24 cycles.', 'interventionNames': ['Drug: Oxaliplatin, LV, 5-FU']}, {'type': 'EXPERIMENTAL', 'label': 'Arm B: FOLFOX4 Stop and go (Oxaliplatin, LV, 5-FU)', 'description': 'The arm B will receive FOLFOX4 for 6 cycles, maintenance with 5FU/LV for 12 cycles, and reintroduction of FOLFOX4 for 6 cycles', 'interventionNames': ['Drug: Oxaliplatin, LV, 5-FU']}], 'interventions': [{'name': 'Oxaliplatin, LV, 5-FU', 'type': 'DRUG', 'otherNames': ['Eloxatin'], 'description': 'Arm B(Intervention arm) will receive FOLFOX4 for 6 cycles, maintenance with 5FU/LV for 12 cycles, and reintroduction of FOLFOX4 for 6 cycles.\n\nFOLFOX4 regimen:\n\nOXA 85mg/m2 , 2 hour infusion, d1 , Leucovorin 200 mg/m2 plus 5-FU 400mg IV bolus, then continuous 22 hour 600 mg/m2 infusion on day 1 and 2 Q2W', 'armGroupLabels': ['Arm A: FOLFOX 4 continuous (Oxaliplatin, LV, 5-FU)', 'Arm B: FOLFOX4 Stop and go (Oxaliplatin, LV, 5-FU)']}]}, 'contactsLocationsModule': {'locations': [{'zip': '210029', 'city': 'Nanjing', 'state': 'Jiangsu', 'status': 'RECRUITING', 'country': 'China', 'contacts': [{'name': 'Xiaofeng Chen, MD', 'role': 'CONTACT', 'email': 'xiaofengch198019@126.com', 'phone': '86 25 83718836', 'phoneExt': '6428'}, {'name': 'Yongqian Shu, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'The 1st Affiliated Hospital Of NanJing Medical University', 'geoPoint': {'lat': 32.06167, 'lon': 118.77778}}, {'zip': '310016', 'city': 'Hangzhou', 'state': 'Zhejiang', 'status': 'RECRUITING', 'country': 'China', 'contacts': [{'name': 'Hongming Pan, MD', 'role': 'CONTACT', 'email': 'panhongming@tom.com', 'phone': '0571-86090073'}, {'name': 'Hongming Pan, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'Zhejiang University affiliated sir run run shaw hospital', 'geoPoint': {'lat': 30.29365, 'lon': 120.16142}}], 'centralContacts': [{'name': 'Yongqian Shu, MD', 'role': 'CONTACT', 'email': 'shuyongqian@csco.org.cn', 'phone': '86 25 83718836', 'phoneExt': '6428'}, {'name': 'Xiaofeng Chen, MD', 'role': 'CONTACT', 'email': 'xiaofengch198019@126.com', 'phone': '86 25 83718836', 'phoneExt': '6428'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Nanjing Medical University', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Nanjing Medical University.', 'oldOrganization': 'Nanjing Medical University'}}}}
