Overview
Brief Summary
This is a Phase II, multi-center study of GM-CT-01 which has been shown to increase the anti-tumor activity of 5-fluorouracil (5-FU) in mice. 5-FU is a chemotherapy drug commonly used in cancer patients. In this Phase II study, patients with colon cancer which has spread, despite treatment with approved therapies, will receive GM-CT-01 plus 5-FU in monthly cycles for at least 2 cycles or until their disease progresses.
Detailed Description
A Phase I study of 40 patients showed that GM-CT-01 in different doses plus 5-FU was well tolerated in patients with different types of solid tumors who failed standard, approved treatments. The main reason for doing this Phase II study in advanced colorectal cancer patients is to verify the safety observations in the early Phase I study and further evaluate the efficacy of these drugs' combination to stabilize tumors, preventing further growth and potentially shrink tumors.
Investigators
Eligibility Criteria
Inclusion Criteria
- •18 years of age or older
- •Has a histologically-proven adenocarcinoma of the colon or rectum
- •Has documentation of locally advanced or metastatic colorectal cancer not amenable to curative surgery or radiotherapy
- •Eligible subjects are those whose unresectable, locally advanced and/or metastatic colorectal cancer has progressed during or after receiving treatment with at least two, but not more than three, lines of therapy that collectively must have included at a minimum all of the following agents: 5-fluorouracil or capecitabine, irinotecan, and oxaliplatin (unless, in the opinion of the investigator, the subject is not able to receive irinotecan and/or oxaliplatin due to medical contraindications, in which case irinotecan and/or oxaliplatin are not required to have been included in the prior lines of therapy). Adjuvant chemotherapy following definitive management of the primary lesion in the colon or rectum is allowed and will not be counted as a line of therapy.
- •Has 1 or more measurable lesion(s) ("target lesion\[s\]") according to RECIST (Response Evaluation Criteria in Solid Tumors) criteria.
- •The same diagnostic imaging method must be used throughout the study to evaluate the lesions; and clinically detected lesions will only be considered measurable when they are superficial (e.g., skin nodules and palpable lymph nodes).
- •Has an ECOG performance status of 0-2
- •Has a life expectancy greater than 3 months
- •Has the ability to understand the nature of the study and any hazards of participating in it; to communicate satisfactorily with the Investigator; and to participate in, and comply with, the requirements of the entire study
- •A female of childbearing potential must have a negative serum screening test for pregnancy and agree to practice abstinence or use an effective method of contraception
Exclusion Criteria
- •Has central nervous system metastasis
- •Has bony metastasis as the sole metastasis
- •Has other concomitant or previous malignancy in the past 3 years, except:
- •adequately treated in situ carcinoma of the uterine cervix;
- •basal or squamous cell carcinoma of the skin; and/or
- •melanoma in situ.
- •Is receiving concomitant anti-neoplastic treatment; has received radiation therapy in the past 3 weeks; has been treated with anti-angiogenesis agents, including bevacizumab, in the past 4 weeks; or has been treated with any other chemotherapeutic agents in the past 4 weeks (6 weeks for mitomycin C and nitrosoureas).
- •Has an active infection
- •Has congestive heart failure (Class III or IV in the New York Heart Association functional classification system)
- •Has a hemoglobin level of \< 8.5 gm/dL
