Condition(s) targeted: Gastrointestinal Cancer Metastatic; Renal Cell Cancer Metastatic; Non Small Cell Lung Cancer Metastatic

Intervention: 5-Fluorouracil and Interferon (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: Western Regional Medical Center

Official(s) and/or principal investigator(s):
Walter Quan, MD, Principal Investigator, Affiliation: Western Regional Medical Center, Inc.


The purpose of this study is to determine whether the combination of a 5-Fluorouracil (5-FU) and interferon, which is able to stimulate the immune system to kill cancer cells, will help to increase tumor shrinkage in previously-treated metastatic gastrointestinal, kidney, or lung Cancer.

Clinical Details

Official title: Phase II Trial of Chemoimmunotherapy With 5-Fluorouracil Followed by Interferon-alfa-2b in Previously-treated Metastatic Gastrointestinal, Kidney, or Lung Cancer

Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Determine the progression free survival of patients with metastatic gastrointestinal, kidney, or lung cancer treated with of interferon-alfa-2b and 5-FU who have had disease progression on at least two prior systemic therapies.

Secondary outcome: Determine the response rate, median duration of response, and median survival of patients treated with this regimen.

Detailed description: Interferon with continuous infusion 5-FU regimens have shown response rates ranging from 0-43% in various cancers. Monthly bolus 5-FU + interferon-alfa-2b has not undergone formal phase II testing. In a small pilot study, a 5 consecutive day schedule of 5-FU and interferon-alfa-2b resulted in the limiting toxicities of diarrhea and mucositis. A more limited schedule was recommended. Therefore, it is reasonable to examine such a schedule. In the current study, 5-FU will be followed by interferon-alfa-2b daily for 3 days to attempt to benefit from both the biochemical and immunologic mechanisms described above.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- Patients must have histologically-proven, metastatic gastrointestinal, kidney, or

lung cancer who have had disease progression on at least two prior systemic therapies.

- ECOG performance status of 0, 1, or 2 and estimated survival of at least 3 months.

- Patients must be felt to have recovered from effects of prior therapy, such as past

expected WBC nadir for chemotherapy (> 2 weeks for most agents, > 6 weeks for nitrosoureas or mitomycin-C)

- Patient consent must be obtained prior to entrance onto study.

- White blood count > 3500/mm3; platelet count of at least 100,000/mm3; hemoglobin >

9. 0 gm/dl; bilirubin, AST, ALT less than 3 times the upper limit of normal; serum creatinine < 1. 8.

- Corticosteroids and immunosuppressive agents are not permitted during the course of

the study. Patients must have received no corticosteroids or immunosuppressive medications at least 2 weeks prior to entrance on-study.

- Patients with elevated temperatures > 100. 5 degrees F, must have sources of occult

infection excluded.

- Women of childbearing potential must have a negative pregnancy test and must take

adequate precautions to prevent pregnancy during treatment. Exclusion Criteria:

- Evidence of significant cardiovascular disease including history of recent (< 6

months) myocardial infarction, uncompensated congestive heart failure, primary cardiac arrhythmias (not due to electrolyte disorder or drug toxicity, for example) beyond occasional PVC's, angina, or cerebrovascular accident.

- Prior history of psychiatric disorder that could be exacerbated by interferon therapy

or which could preclude completion of this therapy.

- Pregnancy or lactation.

- History of hypersensitivity to interferon alfa or fluoropyrimidines.

- History of severe debilitating pulmonary disease, such as chronic obstructive

pulmonary disease requiring continuous oxygen therapy.

- History of autoimmune disease requiring immunosuppression.

- Documented inflammatory joint or systemic inflammatory disease (such as Lupus) which

could be exacerbated by interferon therapy.
