Brief Summary:
The purpose of this study is to determine if the True Human Monoclonal antibody Xilonix (MABp1) can prolong the life of colorectal carcinoma patients that are refractory to standard therapy.

Condition or disease Intervention/treatment Phase
Metastatic Colorectal Cancer Drug: Xilonix Drug: Placebo Phase 3

Detailed Description:

In the setting of refractory, metastatic disease a complete resolution of tumor burden is not a reasonable expectation. Instead, the primary goal of anti-tumor therapy at this stage is to eliminate or reduce the symptomatic effects of the tumor, while trying to prolong survival for as long as possible. Due to treatment related morbidity however, few treatment modalities are ideal for this objective. Even with the most recent targeted agents (such as multi-kinase inhibitors), drug related toxicities frequently lead to relatively short treatment durations. With discontinuation of therapy, disease progression is uncontrolled and prognosis is poor.

New agents that control disease progression-while improving tumor-related symptoms, rather than causing significant therapy related morbidity-are vitally needed to treat patients with advanced cancer, including those with colorectal cancer. An approach has been taken to develop such an agent using a monoclonal antibody to block the chronic inflammation involved in both malignant disease progression and constitutional symptoms.

Xilonix™ is expected to inhibit tumor growth and metastasis by interrupting crucial signals that drive angiogenesis and invasiveness. The antibody therapy may also block tumor microenvironment infiltration by leukocytes (such as myeloid suppressor cells) that suppress antitumor immunity, enabling better host immune control of the disease. In addition to local effects on the tumor, Xilonix™ is expected to work systemically to correct the metabolic dysregulation, fatigue and anxiety mediated by chronic inflammatory signaling to the central nervous system.

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Up to 18 months ]
    Overall survival time was defined as the duration from the date of randomization until death or last follow-up. OS was summarized by Kaplan-Meier method and compared between the treatment groups using un-adjusted log-rank test.


Secondary Outcome Measures :
  1. Change From Baseline in Lean Body Mass (LBM) Measured by Dual-energy X-ray Absorptiometry (DEXA) Scans [ Time Frame: Baseline and Week 8 ]
    Change from baseline in LBM as measured by Dexa scans was reported. DEXA is an X-ray imaging modality used to determine the mass of one material in the presence of another material, using the knowledge of their unique X-ray attenuation at different energies.

  2. Change From Baseline in Symptom Scale and Global Health Status/Quality of Life (QoL) Assessed Through the Cancer-specific European Organization for Research and Treatment of Cancer - Quality of Life Questionnaire (EORTC QLQ-C30) [ Time Frame: Baseline and Week 8 ]
    The EORTC QLQ-C30 questionnaire incorporates nine multi-item scales: 5 functional scales (physical, cognitive, role, emotional, and social); 3 symptom scales (pain, fatigue, and appetite loss) and a Global Health Status/QoL scale. Each item, except Global Health Status, is answered on a four-point scale (1-4): 1-not at all, 2-a little, 3-quite a bit, 4-very much. Response to Global Health Status is measured on a 1 to 7 scale. "1" being very poor and "7" being excellent. Each scale (symptom scale [pain, fatigue, and appetite loss] and Global Health Status/Quality of Life [QoL] scale) was linearly transformed to be in range from 0-100 where a higher score represents good health status, while lower scores indicate poor health status. As planned, the data for symptom scales (pain, fatigue, appetite loss) and a Global Health Status/QoL scale was evaluated and reported.

  3. Change From Baseline in Platelet Counts [ Time Frame: Baseline and Week 8 ]
    Change from baseline in platelet counts up to Week 8 was evaluated.

  4. Progression Free Survival (PFS) [ Time Frame: Up to 18 Months ]
    PFS was defined as time from randomization to tumor progression or death. Progressive Disease defined as increase in tumor burden greater than or equals to (>=) 25 (%) percent relative to nadir (minimum recorded tumor burden) confirmation by a repeat, consecutive assessment no less than 4 weeks from the date first documented. Participants surviving without disease progression at end of study were censored. PFS was compared by Kaplan-Meier method using log-rank test.

  5. Percentage of Participants With Objective Response (OR) [ Time Frame: Up to 18 months ]
    The percentage of OR was estimated by dividing the total number of confirmed complete response (CR) and partial response (PR) by the total number of participants randomized where CR was complete disappearance of all lesions (whether measurable or not, and no new lesions); confirmation by a repeat, consecutive assessment no less than 4 weeks from the date first documented and PR was decrease in tumor burden >= 50 % relative to baseline confirmed by a consecutive assessment at least 4 weeks after first documentation.

  6. Percentage of Participants With Disease Control [ Time Frame: Up to 18 months ]
    Percentage of participants who achieved disease control was estimated by dividing the total number of confirmed CRs, PRs and stable disease (SD) by the total number of participants randomized where CR was complete disappearance of all lesions (whether measurable or not, and no new lesions); confirmation by a repeat, consecutive assessment no less than 4 weeks from the date first documented, PR was decrease in tumor burden >= 50% relative to baseline confirmed by a consecutive assessment at least 4 weeks after first documentation and SD defined as not meeting criteria for CR and PR, in absence of Progressive Disease (increase in tumor burden >= 25 % relative to nadir (minimum recorded tumor burden) confirmation by a repeat, consecutive assessment no less than 4 weeks from the date first documented).
