Current Primary Outcome Measures  ICMJE
 (submitted: January 8, 2019)
Number of Participants With Adverse Events (AEs) by Nature, Severity, and Occurrence Measured From Baseline to End of Trial Participation, as Assessed by the Common Terminology Criteria for AEs (Version 4.03) (CTCAE v4.03). [ Time Frame: 15 months ]
AEs were coded according to the Medical Dictionary for Regulatory Activities (MedDRA) classification. The incidence and type of AEs (e.g., treatment-emergent AE [TEAE]) were summarized according to MedDRA system organ classes and preferred terms. An AE was considered as treatment-emergent if it occurred after the first treatment administration.
Original Primary Outcome Measures  ICMJE

Descriptive Information
Brief Title  ICMJE Sym004 in Combination With FOLFIRI in Metastatic Colorectal Cancer Patients
Official Title  ICMJE An Open Label, Multi-Center Phase 1b/2a Trial Investigating Different Doses of Sym004 in Combination With FOLFIRI in Patients With Metastatic Colorectal Cancer Progressing After First-Line Therapy
Brief Summary This is a Phase 1b/2a study investigating the safety and efficacy of Sym004, an investigational medicinal product (IMP), in combination with FOLFIRI (chemotherapy) when administered every second week (Q2W).
Detailed Description

In the Phase 1b (Dose-Escalation) portion of the trial, patients will be sequentially enrolled to dose-escalation cohorts until establishment of the Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of Sym004 in combination with FOLFIRI.

The Phase 2a (Dose-Expansion) portion of the trial is expected to begin after establishing the RP2D.

Note: In January 2017, the trial was terminated during Phase 1b and enrollment was prematurely discontinued. The primary objective changed to assess the safety of the treatment combination; collection of data for secondary and exploratory objectives was omitted.

Condition  ICMJE Metastatic Colorectal Cancer
Intervention  ICMJE
  • Drug: Sym004
    Sym004 is a 1:1 mixture of 2 monoclonal antibodies (mAbs), which bind specifically to 2 non-overlapping epitopes of the epidermal growth factor receptor (EGFR).
  • Drug: FOLFIRI
    The standard FOLFIRI regimen consists of Irinotecan (180 mg/m^2 IV, infused over 60-90 minutes) concurrently with Folinic Acid (400 mg/m^2 IV, infused over 120 minutes) followed by 5-FU (400 mg/m^2 IV bolus, then 2400 mg/m^2 infused over 46 hours).
    Other Names:
    • Irinotecan (Camptosar)
    • Folinic Acid (Leucovorin)
    • Fluorouracil (5-FU)
