Open-Label Phase IIb Efficacy Trial of Cancer Macrobeads Compared to Best Supportive Care in Colorectal Cancer Patients
- Conditions
- Colorectal Cancers
- Interventions
- Biological: RENCA macrobeads
- Registration Number
- NCT02046174
- Lead Sponsor
- The Rogosin Institute
- Brief Summary
This is a clinical research study of an investigational (FDA IND-BB 10091) treatment for patients with advanced colorectal cancer that no longer responds to standard therapies.
The treatment is being evaluated for its effect on tumor growth. It consists of the placement (implantation) of small beads that contain mouse renal adenocarcinoma cells (RENCA macrobeads). The cells in the macrobeads produce substances that have been shown to slow or stop the growth of tumors in experimental animals and veterinary patients. It has been tested in 31 human subjects with different types of cancers in a Phase I safety trial. Phase II studies in patients with colorectal, pancreatic or prostate cancers are in progress
- Detailed Description
This is a Phase IIb, multicenter, nonrandomized, open-label study with RENCA macrobeads in patients with treatment-resistant, metastatic colorectal carcinoma to determine the effect of RENCA macrobead implantation on overall survival compared with best supportive care.
Two treatment groups will be enrolled in this study, as follows:
* Group A (n=40) - patients who will undergo up to 4 implantations of RENCA macrobeads (no less than 3 months apart), at a dosage level of 8 RENCA macrobeads per kilogram of body weight
* Group B (n=80) - patients who had previously decided (independently of this study) to receive, or continue receiving, best supportive care, defined as management of symptoms aimed at maintaining or improving quality of life, but not including approved therapies targeting the patient's malignancy

Group Intervention Description Macrobead Implantation Arm RENCA macrobeads patients who will undergo up to 4 implantations of RENCA macrobeads (no less than 3 months apart), at an amount of 8 RENCA macrobeads per kilogram of body weight
- Primary Outcome Measures
Name Time Method Overall Survival From date of the most recent scan prior to the first macrobead implantation; assessed up to 32 months. The primary objective of this study was to evaluate the efficacy of RENCA macrobead implantation as assessed by overall survival in subjects with treatment-resistant mCRC.
- Secondary Outcome Measures
Name Time Method Emotional Function Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales (including emotional function), three symptom scales, a global health status score, and six single items.
Emotional Function is assessed from 4 of the 30 questions (Questions 21-24), whose response score ranges on a 4 point scale. The score for role function is calculated based on the average score from these 4 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor functionality) and the maximum value is 100 (best outcome, better functionality). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.Global Health Status Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales, three symptom scales, a global health status score, and six single items.
The Global Health Status is assessed from 2 of the 30 questions (Question 29 and 30), whose response score ranges on a 7 point scale. The score for physical function is calculated based on the average score from these 2 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor) and the maximum value is 100 (best outcome, excellent). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.Performance Status (ECOG Score) Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The Eastern Cooperative Oncology Group (ECOG) performance scale is a 5-point scale, where 0 denotes perfect health and 5 is death. It is used by clinicians to assess disease progression and how the disease is affecting the daily living abilities of the patient. The ECOG Performance Status scores are defined as follows:
* 0: Fully active, able to carry on all pre-disease activities without restriction.
* 1: Restricted in physical strenuous activity, but ambulatory and able to carry out work of a light or sedentary nature (e.g. light house work, office work).
* 2: Ambulatory and capable of all self-care, but unable to carry out any work activities, up and about more than 50% of waking hours.
* 3: Capable of only limited self-care, confined to bed or chair 50% or more of waking hours.
* 4: Completely disabled, cannot carry on any self-care, totally confined to bed or chair.
* 5: DeathRole Function Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales (including role function), three symptom scales, a global health status score, and six single items.
Role Function is assessed from 2 of the 30 questions (Questions 6 and 7), whose response score ranges on a 4 point scale. The score for role function is calculated based on the average score from these 2 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor functionality) and the maximum value is 100 (best outcome, better functionality). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.Pain Assessment Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 Participants were asked to rate their pain on a discrete scale (from 0 = "no pain" to 100 "worst pain imaginable, unbearable"). The worst pain at each time point was used in the analysis.
Activities of Daily Living (KPS Score) Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 Karnofsky Performance Status (KPS) is a self-rated scale that measures the participant's ability to perform daily functions, ranging from 0 ("dead") to 100 ("normal, no complaints, no evidence of disease). Karnofsky scores are defined as follows:
* 100: Normal; no complaints; no evidence of disease
* 90: Able to carry on normal activity with effort, minor sign or symptoms of disease
* 80: Normal activity with effort; some sign or symptoms of disease
* 70: Cares for self; unable to carry on normal activity or do active work
* 60: Requires occasional assistance, but is able to care for most personal needs
* 50: Requires considerable assistance and frequent medical care
* 40: Disabled; requires special care and assistance
* 30: Severely disabled; hospitalization is indicated, although death is not imminent
* 20: Very sick; hospitalization/active support treatment is necessary
* 10: Moribund; fatal processes progressively worsening
* 0: DeadPhysical Function Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 TThe European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales (including physical function), three symptom scales, a global health status score, and six single items.
Physical Function is assessed from 5 of the 30 questions (Questions 1-5), whose response score ranges on a 4 point scale. The score for physical function is calculated based on the average score from these 5 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor functionality) and the maximum value is 100 (best outcome, better functionality). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.Cognitive Function Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales (including cognitive function), three symptom scales, a global health status score, and six single items.
Cognitive Function is assessed from 2 of the 30 questions (Question 20 and 25), whose response score ranges on a 4 point scale. The score for role function is calculated based on the average score from these 2 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor functionality) and the maximum value is 100 (best outcome, better functionality). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.Social Function Baseline; Day 14, 30, 60 post-Implant 1; Day 14, 30, 60 post-Implant 2 The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) consists of 30 questions which pertain to: five functional scales (including social function), three symptom scales, a global health status score, and six single items.
Social Function is assessed from 2 of the 30 questions (Question 26 and 27), whose response score ranges on a 4 point scale. The score for role function is calculated based on the average score from these 2 questions. A linear transformation is used to standardize these responses. Using this linear transformation, the minimum value is 0 (worst outcome, poor functionality) and the maximum value is 100 (best outcome, better functionality). Therefore, increasing values indicate better outcome and decreasing values indicate worse outcome.
