Phase 2b Randomized Controlled Study of Tecemotide (L-BLP25) for Immunotherapy of NSCLC (Non-Small Cell Lung Cancer)

This is a prospective open label, controlled, randomized study to test the safety and efficacy of active specific immunotherapy with tecemotide (L-BLP25) for the treatment of subjects with Stage IIIB or Stage IV non-small cell lung cancer (NSCLC). To be eligible, subjects entering the trial will have to demonstrate either stable disease or a clinical response after first-line treatment (chemotherapy alone, or chemotherapy and radiotherapy) and have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2. Following a 3 week washout period, subjects will be stratified by disease status (either Stage IIIB locoregional disease or Stage IIIB with malignant pleural effusion and Stage IV), and randomized to either best supportive care (BSC) plus tecemotide (L-BLP25) treatment or BSC alone.

Exclusion criteria

  • Received immunotherapy within 4 weeks prior to study entry
  • Received immunosuppressive drugs within 3 weeks prior to study entry
  • Subjects with known brain metastases
  • Past or current history of neoplasm other than lung carcinoma, except for curatively treated non-melanoma skin cancer, in situ carcinoma of the cervix or other cancer curatively treated and with no evidence of disease for at least 5 years
  • Autoimmune disease or immunodeficiency
  • Clinically significant hepatic, renal or cardiac dysfunction
  • Subjects with clinically significant active infection
  • Pregnant or breast feeding women, women of childbearing potential, unless using effective contraception as determined by the investigator
  • Other protocol-defined exclusion criteria could apply

Treatment and study plan

Tecemotide (L-BLP25)

Biological

After receiving single low dose cyclophosphamide, subjects will receive 8 consecutive weekly subcutaneous vaccinations with 1000 microgram (mcg) of tecemotide (L-BLP25) at weeks 0, 1, 2, 3, 4, 5, 6 and 7 followed by maintenance vaccinations (1000 mcg of tecemotide (L-BLP25) at 6-week intervals, commencing at Week 13, until discontinuation from the study due to ECOG status of 4, participation in alternate trial, serious adverse event, or reasons that preclude assessment of clinical status in the opinion of the investigator, and in case of unavailability of study vaccine.

Single low dose cyclophosphamide

Drug

A single intravenous infusion of 300 milligram per square meter (mg/m^2) (to a maximum 600 mg) of cyclophosphamide will be given 3 days before the first vaccine treatment.

Best Supportive Care (BSC)

Other

The BSC will be provided at the investigator's discretion, and may include palliative radiation, psychosocial support, analgesics and nutritional support. Second-line chemotherapy is permitted when indicated for treatment of progressive disease.

Primary outcomes

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, TEAEs Leading to Death, and TEAEs With Cancer and Leukemia Group B (CALGB) Toxicity Grade 3 or 4

    Time frame: From the first dose of study drug administration until 30 days after the last dose of study drug administration or assessed until cut-off date (15 March 2006)

    An adverse event (AE) was defined as any new untoward medical occurrences/worsening of pre-existing medical condition, whether or not related to study drug. A serious AE was an AE that results in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect. Treatment-emergent are events between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Number of participants with TEAEs, serious TEAEs, TEAEs leading to death, and TEAEs with CALGB toxicity Grade 3 or 4 were reported.

  2. Overall Survival Time

    Time frame: Time from randomization to death or last day known to be alive, reported between day of first participant randomized that is, 08 August 2000, up to cut-off (15 March 2006)

    Time from randomization to death or last day known to be alive. Participants without event were censored at the last date known to be alive or at the clinical cut-off date (15 March 2006), whichever was earlier.

Secondary outcomes

  1. Functional Assessment of Cancer Therapy (FACT-L) Questionnaire Score

    Time frame: At baseline, Week 4, Week 8 and then at 12 Week intervals beginning at week 19 until withdrawal/discontinuation from the study.

    Functional Assessment of Cancer Therapy - Lung cancer (FACT-L) is a valid instrument used to measure quality of life (QoL) in participants with cancer consisting of the 27-item FACT-General (G) and 9-item lung cancer subscale (LCS). FACT-G is organized into subscales: physical well-being (PWB)-7 items; social/family well-being (SWB)-7 items; emotional well-being (EWB)-6 items; functional well-being (FWB)-7 items. Each item uses a 5 point rating scale (0="not at all" and 4=equals "very much"). FACT-L total score=4 subscales + LCS and ranges from 0 to 144. Higher scores indicate better QOL.

  2. Number of Participants With Positive T-cell Proliferation

    Time frame: Time from randomization until cut-off date (15 March 2006)

    T-cell proliferation assays were performed and the number of participants with positive mucinous glycoprotein 1 (MUC1) specific T-cell proliferative response were reported.

  3. Number of Participants With Elevated CA27-29 Antigen Levels

    Time frame: Study entry, Week 8

    CA 27-29 is a blood test used to monitor certain types of cancer. CA 27-29 is the name of an antigen, which is a substance that stimulates your body's defense system. CA27-29 antigen levels were determined on all participants and assessed the disease burden of participants at study entry, evaluated early recurrence, presence of residual disease, continued remission or poor prognosis.
