Combination Immunotherapy of GM.CD40L Vaccine With CCL21 in Lung Cancer

"This is a dual-agent, Phase I study with an expansion of each group at the recommended Phase II dose. Participants are entered in cohorts of 3 at the first dose level. Doses are not escalated over the course of treatment of an individual patient.~Phase I: Participants receive the GM.CD40L.CCL21 vaccine in a standard 3+3 design."

Patients randomized to Arm A will receive vaccinations on 3 occasions, at 2 week intervals. 7.5 X 10\^6 irradiated H1944 tumor cells, 7.5 X 10\^6 irradiated H2122 cells, and containing 15 X 10\^6 GM.CD40L cells (1.1 mL) will be injected intradermally into 4 separate sites (0.25 ml injected at each site), in bilateral proximal upper and lower extremities (in the regions of the axillary and inguinal nodal basins). Patients will be restaged approximately 2 weeks after vaccine 3. If patients show no sign of disease progression, patients will then be vaccinated at 4-week intervals.

"This is a dual-agent, Phase I study with an expansion of each group at the recommended Phase II dose. Participants are entered in cohorts of 3 at the first dose level. Doses are not escalated over the course of treatment of an individual patient.~Phase II: Participants are randomized to one of the 2 arms (ratio 1:1): GM.CD40L versus GM.CD40L.CCL21. Patients in Arm B will receive vaccines at the same dose and schedule as described for patients in Arm A. In addition, their vaccine will include H1944 cells expressing CCL21. Note for patients on Arms A and B: the use of steroid medication is to be avoided for 4 weeks before to the initiation of vaccine therapy and during the vaccine treatment period."
