Vaccine Therapy in Treating Patients With Stage II or Stage III Colon Cancer That Has Been Removed During Surgery

2014-08-27 03:56:55 | BioPortfolio

Summary

RATIONALE: Vaccines made from a patient's white blood cells and tumor cells may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining vaccine therapy with chemotherapy may kill more tumor cells.

PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy combined with leucovorin and fluorouracil in treating patients who have undergone surgery to completely remove stage II or stage III colon cancer.

Description

OBJECTIVES:

- Determine safety and immunogenicity of adjuvant autologous tumor cell vaccine in patients with completely resected stage II or III adenocarcinoma of the colon.

OUTLINE: This is a multicenter study. Patients are stratified according to disease stage (II vs III).

Beginning 28-35 days after total surgical resection, patients receive adjuvant autologous tumor cell vaccine intradermally once weekly for 3 vaccinations. The first 2 vaccinations also contain BCG. Patients with stage II disease receive a fourth vaccination 6 months after surgical resection.

Beginning 10-17 days after the third vaccination, patients with stage III disease receive adjuvant leucovorin calcium IV and fluorouracil IV on days 1-5. Chemotherapy continues every 28-35 days for a total of 6 courses. These patients also receive a fourth vaccination 1 month after the completion of chemotherapy.

Patients are followed at 90 days and 6 months.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.

Medical and Biotech [MESH] Definitions

A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)

A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.

A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids. (From Dorland, 28th ed)

A vaccine consisting of DIPHTHERIA TOXOID; TETANUS TOXOID; and whole-cell PERTUSSIS VACCINE. The vaccine protects against diphtheria, tetanus, and whooping cough.

A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
