Immunologic Response After Pandemic Influenza A (H1N1) Vaccine in Onco- Hematologic Patients

January 5, 2024 updated by: Paolo Corradini

Evaluation of Immunologic Response After Pandemic Influenza A (H1N1) Vaccine in Oncologic and Hematologic Patients

Primary objective

1) To assess whether oncologic and hematologic patients develop a protective immunological response after pandemic Influenza A (H1N1) vaccine

Secondary objectives

  1. To compare the levels of antibody response against A (H1N1) influenza virus between oncologic and hematologic patients relative to a cohort of healthy volunteers
  2. To assess the incidence of A (H1N1) infection in vaccinated oncologic and hematologic patients in comparison with a cohort of vaccinated healthy volunteers. To assess the clinical symptoms attributable to influenza infection in vaccinated oncologic and hematological patients and healthy volunteers.
  3. To compare the levels of antibody response against A (H1N1) influenza virus between the following subgroups: patients with ongoing chemotherapy; patients who have completed the chemotherapy treatment; patients treated with autologous or allogeneic peripheral blood hematopoietic stem cell transplant (PBSCT)

Study procedures: Onco-hematological patients will perform a blood sample collection before the vaccination, on day +21 after vaccination , on day +50 and on day +90. At the end of the collection, the investigators will perform immunological test to evaluate the antibody titer and the cellular response. The titer of antibodies against the vaccine strain will be measured in all samples by hemagglutination-inhibition (HI) assays with the use of turkey erythrocytes and according to EMEA guidelines. Response criteria will be the achievement of a protective title of HI test > 1:40. In addition, the investigators will evaluate: geometric mean titers and a fourfold titer increase compared with prevaccination titers. Cellular-mediated response will be analysed by flow-cytometry. A control cohort of healthy volunteers who received A(H1N1) vaccine will perform the same blood sample collection.

Evaluation of clinical response: Oncologic and hematologic patients will be followed as outpatients or inpatients according to routine controls for their disease. In case that symptoms of the upper airways or influenza-like symptoms develop, the symptoms will be recorded in the clinical database, nasal and pharyngeal swaps will be performed according to the doctor who is taking care of the patient. In order to evaluate the clinical efficacy of the vaccination, the swaps will be tested for A (H1N1) influenza virus infection. No further studies will be performed after 3 months from the vaccination.

  1. To compare the levels of antibody response against A (H1N1) influenza virus between oncologic and hematologic patients relative to a cohort of healthy volunteers

To compare the levels of antibody response against A (H1N1) influenza virus between the following subgroups: patients with ongoing chemotherapy; patients who have completed the chemotherapy treatment; patients treated with autologous or allogeneic peripheral blood hematopoietic stem cell transplant (PBSCT) Study population and design

The study population consists consecutive patients with oncologic or hematologic diseases who are planned to receive A (H1N1) influenza vaccine

Study procedures The patients will perform a blood sample collection (serum vial) on day 0 (range: 0- 2 days before vaccination) before the vaccination, a blood sample collection (serum vial) on day +21 (range: +/- 5 days) after vaccination , a blood sample collection (serum vial) on day +50 (range: +/- 5 days) and on day +90 range: +/- 5 days) after vaccination. The samples will be frozen in 500 mcl aliquots at -20°C. At the end of the collection we will perform immunological test to evaluate the antibody titer and the cellular response. The serum samples will be stored at the laboratory of Virology of the University of Milan. The titer of antibodies against the vaccine strain will be measured in all samples by means of hemagglutination-inhibition (HI) assays with the use of turkey erythrocytes and according to EMEA guidelines. Response criteria will be the achievement of a protective title of HI test > 1:40. In addition we will evaluate: geometric mean titers and a fourfold titer increase compared with prevaccination titers. Cellular-mediated response will be analysed by incubating CD3+ patients' cells with influenza A Antigens and evaluation of: 1) cellular expansion by flow-cytometry analysis of dilution of carboxyfluorescein succinimidyl ester (CFSE); 2) IFN-gamma production by ELISPOT.

A control cohort of healthy volunteers who received A(H1N1) vaccine will perform the same blood sample collection in order to compare the immunological response between oncologic and hematologic patients relative to healthy cohort.

Evaluation of clinical response:

Oncologic and hematologic patients will be followed as outpatients or inpatients according to routine controls for their disease. In case that symptoms of the upper airways or influenza-like symptoms develop, the symptoms will be recorded in the clinical database, nasal and pharyngeal swaps will be performed according to the doctor who is taking care of the patient. In order to evaluate the clinical efficacy of the vaccination, the swaps will be tested for A (H1N1) influenza virus infection.

No further studies will be performed after 3 months from the vaccination.

Sample size The trial will accrue 25 patients for each subpopulation to be analyzed. This sample size has a 90% power to evaluate an increase of the probability to have a biological response from a theoretical value of 20% (low efficacy of the vaccine) to a value of 50% (target of effectiveness) at the 5% significance (student t test, one tail). The subpopulations are as follows: patients with ongoing chemotherapy; patients who have completed the chemotherapy treatment; patients treated with autologous or allogeneic transplant of hematopoietic stem cell.

We will accrue a "calibration" group comprising at least 100 healthy volunteers. This group will comprise people working at the National Cancer Institute in Milan who have signed an informed consent to participate to the study. This size of the sample allows a precision on the evaluation of the probability of obtaining a biological response (half of the confidence interval) that is not lower than 10%

Study duration The estimated duration of enrolment is of 6 months. The enrolment of the hematologic and oncologic patients and of the cohort of healthy volunteers will be performed in 3 months and the study will be closed on day +90 with a blood sample collection.
