A Phase I Trial of CCL21 Gene Modified Dendritic Cells In Non-Small Cell Lung Cancer



- To determine the safety, toxicity, and maximum tolerated dose (MTD) of autologous
dendritic cell-adenovirus CCL21 vaccine administered as an intratumoral injection in
treating patients with stage IIIB, IV, or recurrent non-small cell lung cancer.


- To determine the biologic and clinical responses to therapy.

- To determine treatment-related toxicity using the NCI Common Toxicity Criteria.

- To identify the MTD.

- To monitor patients for evidence of autologous dendritic cell-adenovirus CCL21
vaccine-induced cytokines and antigen-specific immune responses.

- To detect immune responses to tumor-associated antigens and vector.

- To assess patients for objective signs of tumor regression (RECIST Criteria).

OUTLINE: This is a dose-escalation study of autologous dendritic cell-adenovirus CCL21

Patients undergo leukapheresis to obtain leukocytes for generation of autologous dendritic
cells (DC). Adenovirus carrying the CCL21 gene is added to the dendritic cells to make the
vaccine. Approximately 2 weeks after leukapheresis, patients receive an intratumoral
injection of autologous dendritic cell-adenovirus CCL21 vaccine under CT-guidance or by
bronchoscopy on days 0 and 7. Patients demonstrating a clinical response are eligible to
receive a second round of gene transfer at their discretion and in consultation with the

Cohorts of 3 patients receive escalating doses of autologous dendritic cell-adenovirus CCL21
vaccine until the maximum tolerated dose (MTD) is determined. An additional 12 patients are
treated at the MTD.

Patients undergo blood sample collection at baseline and then on days 0, 7, 14, 28, and 56
for safety and immunological studies. Blood samples are analyzed for mycoplasma by PCR;
dendritic cell phenotype by flow cytometry; detection of adenovirus CCL21 by nested PCR; and
adenoviral antibodies by ELISA. Patients also undergo tissue aspirate or biopsy on days 0
and 7 (during bronchoscopy or CT-guided procedure). Tissue samples are analyzed for
immune-modulating cytokines (i.e., IFNγ, CXCL9, and CXCL10) by quantitative RT-PCR;
detection of tumor infiltrating leukocytes by immunohistochemistry; CD83+ DC, CXCR3, CCR7,
CCL21 and CD3+ T-cells, CD4, and CD8 by flow cytometry; determination of tumor expression of
tumor-associated antigen by RT-PCR; and evaluation of immune modulation by ELISPOT assays.

After completion of study treatment, patients are followed periodically.

Inclusion Criteria:

- Adults over the age of 21 capable of giving informed consent

- Pathologically confirmed non-small cell lung cancer (NSCLC)

- Stage IIIB, IV, or recurrent disease

- Progressive disease despite one or more prior chemotherapy regimens as standard of
care OR patient refuses standard chemotherapy

- Measurable metastatic disease by RECIST guidelines

- Patients with a major endobronchial lesion in the segmental, lobar, or mainstem
bronchus with complete obstruction of the airway may be eligible for bronchoscopic
injection provided there is no evidence of respiratory failure (defined as SaO_2 >
90% on room air, PCO_2 < 45 mm Hg, or FEV_1 > 1.0 L)

- Patients with an endobronchial lesion in the segmental bronchus with variable
stenosis (not completely obstructed) and not amenable to standard palliative airway
treatments (i.e., laser and stenting) may be eligible for bronchoscopic injection if
there is no evidence of respiratory failure (defined as SaO_2 > 90% on room air,
PCO_2 < 45 mm Hg, or FEV_1 > 1.0 liters)

- Patients with bullous disease may undergo CT-guided transthoracic injection provided
the targeted tumor has an intended needle path without crossing bullae

- More than 30 days since prior and no concurrent corticosteroids

- More than 30 days since prior radiotherapy, chemotherapy, or noncytotoxic
investigational agents

Exclusion Criteria:

- active CNS metastasis (i.e., progression of CNS disease during the past 30 days
without intervention)

- evidence of coagulopathy, defined as PT and/or PTT ≤ 1.5 times ULN OR platelets ≥

Hg, or FEV_1 > 1.0 L)

- NYHA class III-IV cardiac disease within the past year

- myocardial infarction within the past year

- comorbid disease or medical condition that would impair the ability of the patient to
receive or comply with the study protocol

- signs or symptoms of acute adenoviral infection (i.e., conjunctivitis or documented
adenoviral upper respiratory infection)

- prior or concurrent evidence of autoimmune disease
