About

This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Solid Invasive Tumors and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects. Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.

Inclusion criteria

For Invasive Solid Tumor Subjects:

  • Subjects between 2 and 70 years of age (inclusive)
  • Any sex or ethnicity
  • Confirmed diagnosis of Invasive Solid Tumor or hematological malignancies in complete remission for at least 3 months and not more than 18 months after the last neo-adjuvant and/or adjuvant chemotherapy cycle according to investigators assessment and the subjects medical records
  • Previous use of neo-adjuvant and/or adjuvant chemotherapy for the treatment on an invasive solid tumor
  • Life expectancy of at least 12 months
  • Karnofsky Performance Scale > 40%

Childbearing potential women must be willing to use an acceptable contraceptive method. Acceptable contraceptive methods are defined as one or more of the following:

  • Hormone contraceptive (such as oral, injectable, transdermal patch, subcutaneous implant, cervical ring)
  • Barrier (condom with spermicide or diaphragm with spermicide) at each intercourse and during the whole intercourse
  • Intra-uterine device (IUD)
  • Monogamous relation with vasectomized partner (must have been vasectomized at least six months before the volunteer entered the study).
  • Subjects capable of following all the study procedures and available for all visits scheduled to the investigation site
  • Subjects capable of understanding the nature and risk of the study proposed and sign the consent form
  • In case of children and adolescents (below 18 years of age): Subjects capable of understanding the nature of the study and whose legal guardian understands the nature and risk of the study proposed and signs the consent form
  • The study subjects may have other underlying chronic diseases that do not involve immunosuppression (e.g. osteoarticular diseases, cardiorespiratory diseases, metabolic diseases, stable, non progressive, non-severe neurologic disorders without cognitive impairment, ophthalmologic diseases, etc.), but their symptoms/signs must be under control through medical follow-ups and drug therapy

For Healthy Subjects:

  • Subjects between 2 and 70 years of age (inclusive)
  • Any sex and ethnicity
  • Subjects with good health as determined by medical history, physical evaluation, and investigator's clinical opinion

Childbearing potential women must be willing to use an acceptable contraceptive method. Acceptable contraceptive methods are defined as one or more of the following:

  • Hormone contraceptive (such as oral, injectable, transdermal patch, subcutaneous implant, cervical ring)
  • Barrier (condom with spermicide or diaphragm with spermicide) at each intercourse and during the whole sexual intercourse
  • Intra-uterine device (IUD)
  • Monogamous relation with vasectomized partner (must have been vasectomized for at least six months before the volunteer entered the study).
  • Subjects capable of respecting all the study procedures and available for all the visits scheduled at the investigation site
  • Subjects capable of understanding the nature and risk of the study proposed and sign the consent form
  • In case of children and adolescents (below 18 years of age): Subjects capable of understanding the nature of the study and whose legal guardian understands the nature and risk of the study proposed and signs the consent form

  • Receipt of parenteral immunoglobulin, hemotherapy, and/or plasma derivatives within 3 months prior to inclusion in the study
  • Receipt of any investigational product within 12 months prior to inclusion in the study

For Healthy Subjects:

  • Previous laboratory confirmed diagnosis of an infection by the new virus H1N1
  • Receipt of another vaccine against the new virus H1N1 within 3 months prior to inclusion in the study
  • Any recent vaccine given within the last 21 days (inclusive)
  • History of allergic reaction to influenza vaccine in the past, or a current or previous allergy to egg or egg protein, kanamycin, and neomycin sulfate;
  • Acute febrile disease (the vaccination may be delayed up to 3 days after symptoms resolution)
