A Phase III Study of Xilonix in Patients With Advanced Colorectal Cancer

Phase 3
Terminated
Conditions
Metastatic Colorectal Cancer
Interventions
Drug: Placebo
Registration Number
NCT01767857
Lead Sponsor
Janssen Research & Development, LLC
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.

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.

Inclusion Criteria
  1. Subjects with pathologically confirmed colorectal carcinoma that is metastatic or unresectable and which is refractory to standard therapy. To be considered refractory, a subject must have experienced progression (or intolerance) after treatment with standard approved regimens including, oxaliplatin, irinotecan flouropyrimidine, bevacizumab, and cetuximab or panitumumab if KRAS wildtype.
  2. Subjects will not be treated with any radiation, chemotherapy, or investigational agents while enrolled in this protocol.
  3. Eastern Cooperative Oncology Group (ECOG) performance status 0,1, or 2.
  4. At least 2 weeks since the last previous cancer treatment including: chemotherapy, radiation therapy, immunotherapy, surgery, hormonal therapy, or targeted biologics.
  5. Age ≥ 18 years, male or female subjects.
  6. Serum potassium and magnesium levels within institutional normal limits. Total serum calcium or ionized calcium level must be greater than or equal to the lower limit of normal.
  7. Adequate renal function, defined by serum creatinine ≤ 1.5 x ULN.
  8. Adequate hepatic function
  9. Adequate bone marrow function
  10. For women of childbearing potential (WOCBP), a negative serum pregnancy test result at Screening.
  11. Signed and dated institutional review board (IRB)-approved informed consent before any protocol-specific screening procedures are performed.
  12. Patients enrolled must, in the Investigator's judgment, be healthy enough to stay on the clinical trial for three months.
Exclusion Criteria
  1. Mechanical obstruction that would prevent adequate oral nutritional intake.
  2. Serious uncontrolled medical disorder, or active infection, that would impair the ability of the patient to receive protocol therapy.
  3. Uncontrolled or significant cardiovascular disease, including:
  4. Dementia or altered mental status that would prohibit the understanding or rendering of informed consent.
  5. Subjects who have not recovered from the adverse effects of prior therapy at the time of enrollment to ≤ grade 1; excluding alopecia and grade 2 neuropathy.
  6. Immunocompromised subjects, including subjects known to be infected with human immunodeficiency virus (HIV).
  7. Known hepatitis B surface antigen and/or positive hepatitis C antibody and presence of hepatitis C RNA.
  8. History of tuberculosis (latent or active) or positive Interferon-gamma release assay (IGRA).
  9. Receipt of a live (attenuated) vaccine within 1 month prior to Screening
  10. Subjects with history of hypersensitivity to compounds of similar chemical or biologic composition of XILONIX™.
  11. Women who are pregnant or breastfeeding.
  12. WOCBP or men whose sexual partners are WOCBP who are unwilling or unable to use an acceptable method of contraception for at least 1 month prior to study entry, for the duration of the study, and for at least 3 months after the last dose of study medication.
  13. Weight loss >20% in the previous 6 months.

Primary Outcome Measures
NameTimeMethod
Overall Survival (OS)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
NameTimeMethod
Change From Baseline in Platelet CountsBaseline and Week 8

Change from baseline in platelet counts up to Week 8 was evaluated.

Change From Baseline in Lean Body Mass (LBM) Measured by Dual-energy X-ray Absorptiometry (DEXA) ScansBaseline 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.

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)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.

Progression Free Survival (PFS)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.

Percentage of Participants With Objective Response (OR)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.

Percentage of Participants With Disease ControlUp 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).
