Ambispective Observational Multicenter Study on the Efficacy of the Third Dose of Vaccine Anti COVID-19 in Patients Suffering From Solid Tumors Undergoing Oncological Treatment Active.

March 27, 2024 updated by: Fondazione IRCCS Policlinico San Matteo di Pavia
To evaluate the serum neutralizing antibody titre in cancer patients undergoing active treatment against variants (VOC) before and after the third dose of BNT162b2 COVID-19 vaccine.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

  2. Life expectancy (estimated by the treating doctor) ≥ 6 months;
  3. Histological diagnosis confirmed solid neoplasm;
  4. Under active treatment
  5. Previous two doses of Pfizer anti-SARS-CoV-2 vaccine received (will be considered also patients who have completed the vaccination cycle with other mRNA vaccines - Modern-)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Determination of the change in neutralizing antibodies against SARS-CoV-2 (CLIA method) towards VOCs before the third dose of COVID-19 vaccine and 21 days after the same.
Time Frame: 3 weeks
The immune response to viral variants will be evaluated by neutralization tests. In detail, previously titrated and characterized viral isolates representative of the alpha, beta, gamma and delta variants will be used. Any new variants relevant from a clinical and epidemiological point of view will subsequently be taken into consideration. A positive neutralizing titer is considered to be a titer equal to or greater than 1:10
3 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluation of the kinetics of neutralizing antibodies and anti-SARS-CoV-2 IgG titer (CLIA method) up to 52 weeks after the third dose of COVID-19 vaccine
Time Frame: 0, 3, 26, 52 weeks
The difference in antibody titers from time 0, at 3 and 26 weeks, up to week 52
0, 3, 26, 52 weeks
Evaluation of the incidence of virologically confirmed cases of VOC after administration of the third dose of vaccine.
Time Frame: 52 weeks
The incidence will be expressed as patients per 100 people per year.
52 weeks
Evaluation of the incidence of local and systemic adverse reactions (ARs), directly or indirectly linked to the vaccine, in an observation period up to 4 weeks later the third dose of vaccine.
Time Frame: 4 weeks
The incidence will be expressed as patients per 100 people per year.
4 weeks
Evaluation of the incidence of "New onset" immune-related adverse events (IRAEs), such as immune-related pruritus, rashes, hypophysitis, hepatitis, pneumonia, diarrhoea, colitis in patients undergoing immunotherapy.
Time Frame: 52 weeks
The incidence will be expressed as patients per 100 people per year.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 17, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
January 8, 2023

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
