Monoclonal Antibody Therapy in Treating Patients With Progressive Small Cell Lung Cancer (SCLC)

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: This phase I trial is studying the side effects of monoclonal antibody therapy in treating patients with progressive small cell lung cancer (SCLC).

About this study

OBJECTIVES:

Primary

  • Determine the targeting, tissue distribution, and pharmacokinetics of monoclonal antibody hu3S193 in patients with progressive small cell lung cancer (SCLC).

Secondary

  • Determine the immunogenicity of of monoclonal antibody hu3S193 in patients with progressive small cell lung cancer (SCLC).
  • Determine tumor response of monoclonal antibody hu3S193 in patients with progressive small cell lung cancer (SCLC).
  • Determine the safety of tof monoclonal antibody hu3S193 in patients with progressive small cell lung cancer (SCLC).

OUTLINE: This is an open-label, pilot study.

Patients received monoclonal antibody hu3S193 (mAb hu3S193) intravenously (IV) over 30 minutes on day 1 of weeks 1-4. Patients also received indium-111 (111In) radiolabeled hu3S193 IV over 30 minutes on day 1 of weeks 1 and 4 and then underwent gamma camera imaging. Treatment continued in the absence of disease progression or unacceptable toxicity.

Patients were followed at 1 and 4 weeks, every 3 months for 1 year, and then every 6-12 months thereafter.

Primary outcomes

  1. Confirmation of Tumor Targeting as Measured by the Number of Patients With Assessable Lesions Greater Than or Equal to 2 cm Measured by FDG-PET and SPECT Imaging.

    Time frame: 28 days

    Gamma camera imaging, including planar scans and single-photon emission computed tomography (SPECT) scans, were carried out immediately following completion of infusion and on two subsequent occasions during the next 6 days after the infusions of 111In-hu3S193 on weeks 1 and 4. A pretreatment FDG-positron emission tomography PET/CT scan was performed within 2 weeks of study entry per standard clinical methods for comparison with gamma camera imaging. FDG-PET/ CT scans and 111In planar and SPECT scans were evaluated for extent of disease and antibody targeting, respectively. Lesions on FDG-PET/CT scans were considered positive if uptake of radiotracer was visually greater than surrounding tissue, with a standard uptake value greater than 3.

Secondary outcomes

  1. Mean Half-life (T1/2) as Measured by 111In-hu3S193 Radioactivity

    Time frame: 4 weeks (days 1, 2, 3, and 5; weeks 1 and 4)

    Blood samples for analysis of radioactivity and serum concentration of hu3S193 were obtained immediately before and 5, 60, and 120 minutes post-infusion, before and after imaging on day 2, and on days 3 and 5 after completion of the 111In-hu3S193 infusion in weeks 1 and 4. Pharmacokinetics was calculated using WinNonLin (Pharsight Co., Mountain View, CA). A two-compartment model was fitted to individually labeled infusions for each patient using unweighted nonlinear least squares to calculate pharmacokinetic parameters.

  2. Mean Volume of Distribution of Central Compartment (V1) as Measured by 111In-hu3S193 Radioactivity

    Time frame: 4 weeks (days 1, 2, 3, and 5; weeks 1 and 4)

    Blood samples for analysis of radioactivity and serum concentration of hu3S193 were obtained immediately before and 5, 60, and 120 minutes post-infusion, before and after imaging on day 2, and on days 3 and 5 after completion of the 111In-hu3S193 infusion in weeks 1 and 4. Pharmacokinetics was calculated using WinNonLin (Pharsight Co., Mountain View, CA). A two-compartment model was fitted to individually labeled infusions for each patient using unweighted nonlinear least squares to calculate pharmacokinetic parameters.

  3. Mean Clearance (CL) as Measured by 111In-hu3S193 Radioactivity

    Time frame: 4 weeks (days 1, 2, 3, and 5; weeks 1 and 4)

    Blood samples for analysis of radioactivity and serum concentration of hu3S193 were obtained immediately before and 5, 60, and 120 minutes post-infusion, before and after imaging on day 2, and on days 3 and 5 after completion of the 111In-hu3S193 infusion in weeks 1 and 4. Pharmacokinetics was calculated using WinNonLin (Pharsight Co., Mountain View, CA). A two-compartment model was fitted to individually labeled infusions for each patient using unweighted nonlinear least squares to calculate pharmacokinetic parameters.

  4. Mean Area Under the Curve (AUC) as Measured by 111In-hu3S193 Radioactivity

    Time frame: 4 weeks (days 1, 2, 3, and 5; weeks 1 and 4)

    Blood samples for analysis of radioactivity and serum concentration of hu3S193 were obtained immediately before and 5, 60, and 120 minutes post-infusion, before and after imaging on day 2, and on days 3 and 5 after completion of the 111In-hu3S193 infusion in weeks 1 and 4. Pharmacokinetics was calculated using WinNonLin (Pharsight Co., Mountain View, CA). A two-compartment model was fitted to individually labeled infusions for each patient using unweighted nonlinear least squares to calculate pharmacokinetic parameters.

  5. Immunogenicity of hu3S193 as Measured by the Number of Patients With Human Anti-human Antibodies (HAHA) After Treatment With hu3S193.

    Time frame: 4 weeks (pre-dose, weeks 1, 2, 3, and 4)

    Blood samples to measure human anti-human antibody (HAHA) assessments were obtained at baseline and each week before hu3S193 dosing. Measurement of immune responses to hu3S193 in patient blood samples was analyzed using a BIACORE (Piscataway, NJ) instrument using surface plasmon resonance (SPR).

  6. Number of Patients With Tumor Responses After Treatment With hu3S193 as Measured by RECIST

    Time frame: up to 28 days

    Tumor response was assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST). Per RECIST, target lesions are categorized as follows: complete response (CR): disappearance of all target lesions (no evaluable disease); partial response (PR): ≥ 30% decrease in the sum of the longest diameter of target lesions; progressive disease (PD): ≥ 20% increase in the sum of the longest diameter of target lesions; stable disease (SD): small changes that do not meet above criteria (Therasse P et al. 2000).
