  Purpose

RATIONALE: Studying the dendritic cells in samples of blood from patients with cancer receiving aflibercept may help doctors learn about the effect of aflibercept on dendritic cells.

PURPOSE: This laboratory study is evaluating dendritic cells in patients with advanced solid tumors or non-Hodgkin lymphoma receiving aflibercept on clinical trial VGFT-ST-0202.

Primary Outcome Measures:
  • Effect of in vivo aflibercept on the presence of different populations of dendritic cells (DC) and immature cells (ImC) [ Time Frame: at days 15, 29 and 64 ] [ Designated as safety issue: No ]
  • Effect of aflibercept administration on DC function based on ability to stimulate antigen specific proliferative (allogeneic and tetanus toxoid) and cytolytic T cell responses (influenza) [ Time Frame: at days 15, 29 and 64 ] [ Designated as safety issue: No ]
  • Correlation of aflibercept level with host antigen presenting cell phenotype at baseline [ Time Frame: at days 15, 29 and 64 ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples Without DNA

50cc of peripheral blood will be collected in CPT tubes for mononuclear cell isolation and 10cc in SST tubes for plasma collection.

Detailed Description:

OBJECTIVES:

  • Evaluate the effect of in vivo aflibercept on the presence of different populations of dendritic cells (DC) and immature cells (ImC) in the peripheral blood of cancer patients by characterizing the time course (kinetics) of the improvement in antigen presenting cell (APC) phenotype (decline in DC/ImC ratio) occurring early and late after aflibercept administration.
  • Evaluate the effect of aflibercept administration on DC function based on ability to stimulate antigen specific proliferative (allogeneic and tetanus toxoid) and cytolytic T cell responses (influenza) by characterizing the time course (kinetics) of the improvement in APC function occurring early and late after aflibercept administration.
  • Explore the relationship of baseline aflibercept level and host APC phenotype.

OUTLINE: This is a multicenter study.

Patients undergo phlebotomy and blood collection at baseline and on days 15, 29, and 57. Samples are analyzed for dendritic cell phenotype, subpopulations, maturation status, and function in terms of ability to activate autologous T cells.
