73The purpose of this study is to find out what effects (good and bad) a tumor vaccine used in combination with GM.CD40L and CCL21 have on the patient and their cancer. We also want to find out if the vaccine and the drugs can boost the immune system of these patients and how their immune system reacts, both before and after the vaccine treatment.
The vaccine will be made by mixing two kinds of cells: 1) some lung cancer cells, which have been grown in the lab, and 2) experimental "bystander (present but not taking part in the immune response)" cells. All the cells in the vaccine will be treated with high-dose X-rays to make sure that none of them grow and cause more cancer. The bystander cells are human cells that have been genetically changed to express GM-CSF and CD40L. These are called "GM.CD40L". (That is the original cells, called K562, with the genes for human GM-CSF and CD40L inserted into them). These changes are designed to help boost the participants' immune system to better fight the cancer in their body. GM-CSF is a hormone that is known to stimulate bone marrow to make more white blood cells.
CCL21 is a chemokine (protein) that helps to recruit T cells (a type of white blood cell that helps to protect the body from infections) and leads to hyper-responsive T cells. This leads to heightened immune responses when T cells are exposed to both CCL21 and antigen (a substance that when introduced into the body lead to production of an antibody)-presenting cells (A cell that can "present" antigen in a form that T cells can recognize it ). The induction of a strong cell-mediated immune response is the type of immunity expected to be most involved in controlling cancer cell growth. A randomized trial of a vaccine consisting of the GM.CD40L bystander cells and an equivalent number of allogeneic (taken from different individuals) tumor cells plus or minus CCL21 is proposed.
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.
Participants enrolled in the Phase I trial will receive GM.CD40L.CCL21 vaccinations on 3 occasions, at 2 week intervals. Note for the phase I portion: the use of steroid medication is to be avoided for 4 weeks prior to the initiation of vaccine therapy and during the vaccine treatment period.
Arm A participants will receive GM.CD40L cells vaccinations on 3 occasions, at 2 week intervals. Note on either 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.
Arm B participants will receive GM.CD40L.CCL21 vaccinations on 3 occasions, at 2 week intervals. Note on either 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.

Highest dose level of GMCD40L vaccine in combination with CCL21 that induced dose limiting toxicity (DLT) in fewer than 33% of patients. DLT: Intervention-specific acute toxicity; i.e., occurrence within 28 days of drug administration, according to the NCI Common Toxicity Criteria for Adverse Events (CTCAE), V 4: 1.) that precludes further dose escalation. 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. If 2 or more patients experience toxicity in dose level 1 (30X10^6 cells per injection), dose de-escalation will occur. Dose level -1 will be defined by 10 % reduction of cells administered from dose level 1 and follow the same rules. It is not feasible to escalate the dose of the vaccine beyond 30X10^6 cells per injection; therefore the Maximum Tolerated Dose (MTD) may not be reached in this study. In that case, the highest dose level will be used in the phase II component.
PFS is measured as the time from start of treatment to progression or death. 6 month progression free survival will be estimated from available clinical and radiographic assessments and RECIST 1.1 will be used to make tumor measurements. Progressive Disease (PD) = 20% increase in the sum of the longest diameter of target lesions.
Response according to Response Evaluation in Solid Tumors (RECIST) 1.1. Complete Response (CR): Complete disappearance of all measurable and non-measurable disease; No new lesions. Partial Response (PR): Applies only to patients with at least one measurable lesion; Greater than or equal to 30% decrease under baseline of the sum of longest diameters of all target measurable lesions. Progressive Disease (PD): 20% or greater increase in the sum of longest diameters of target measurable lesions over smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline. Unequivocal progression of non-measurable disease in the opinion of the treating physician (an explanation must be provided). Appearance of any new lesion/site. Stable Disease (SD): Does not qualify for CR, PR, Progression or Symptomatic Deterioration; All target measurable lesions must be assessed using the same techniques as baseline.
