Alternate Title

Chemotherapy Followed By Vaccine Therapy in Treating Patients With Extensive-Stage Small Cell Lung Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II, Phase I Treatment Closed 18 and over Other MCC-13427 MCC-6260, MCC-IRB-0147/NE, MCC-0205538, MCC-12614, NCT00049218

Objectives

1. Determine the maximum tolerated dose of autologous dendritic cell-adenovirus p53 vaccine, administered after standard chemotherapy, in patients with extensive stage small cell lung cancer.
2. Determine the toxicity of this regimen in these patients.
3. Determine the development of an anti-p53-specific immune response in these patients after treatment with this regimen.
4. Determine the tumor response rate, time to progression, and overall survival of patients treated with this regimen.
5. Determine the frequency of anti-adenovirus immune responses in these patients after treatment with this regimen.

Outline

This is a dose-escalation study of autologous dendritic cell-adenovirus p53 vaccine.

Patients undergo leukapheresis and dendritic cells are cultured. Adenovirus carrying p53 gene particles are added to the dendritic cells to make the vaccine. Leukapheresis is performed before chemotherapy or 8 weeks after the last dose of chemotherapy if the patient has already started chemotherapy.

Patients receive standard chemotherapy before receiving the vaccine. The recommended regimen is carboplatin IV over 1 hour on day 1 and etoposide IV over 1 hour on days 1-3. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients with progressive disease (PD) at 6 weeks after chemotherapy are removed from the study.

• Phase I: Beginning 9 weeks after completion of chemotherapy, patients receive autologous dendritic cell-adenovirus p53 vaccine subcutaneously (SC) on days 1, 14, and 28. Patients without PD may undergo repeat leukapheresis on day 49. Patients receive vaccine SC again on days 56, 84, and 112 in the absence of disease progression or unacceptable toxicity.

  Cohorts of 3-6 patients receive escalating doses of autologous dendritic cell-adenovirus p53 vaccine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.




• Phase II: Patients receive autologous dendritic cell-adenovirus p53 vaccine at the MTD determined in phase I.

Patients are followed at day 140 and then every 3 months thereafter.
