Immunological Responses of COVID-19 Vaccination

February 17, 2023 updated by: Alberto J. Montero, University Hospitals Cleveland Medical Center

Long Term Immunological Responses of COVID-19 Vaccination in Cancer Patients on Chemotherapy: a Pilot Study

Cancer patients with COVID-19 have a 30% higher mortality rate compared to the general population and are considered a high-risk group by the American Association for Cancer Research that should be given "high priority" during COVID-19 vaccine administration. Although studies have suggested that vaccination during active treatment with chemo and/or radiation therapy provides suboptimal antibody response, the studies were underpowered and heterogeneous thus putting this conclusion into question. We need data in cancer patients on immunosuppressive chemotherapy at the time of COVID vaccination to understand how immune responses compare to healthy controls and cancer patients not on immunosuppressive therapy.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Group A will consist of 50 participants with a diagnosis of one of the following cancers: breast, colorectal, or prostate cancers who received myelosuppressive cytotoxic chemotherapy at the time of COVID vaccination, or who received chemotherapy within 30 days prior to the initial or booster vaccination, or who started on chemotherapy within 30 days after the initial or booster COVID vaccination. Group B will consist of 25 participants with a diagnosis of breast, colorectal, or prostate cancers who are on non-myelosuppressive treatment including endocrine therapy, tyrosine kinase inhibitor or anti-HER 2 therapy. Group C will consist of 25 age matched adult participants with no prior history of cancer or prior history of non-metastatic solid cancer invasive cancer treated with a curative intent, without evidence of disease recurrence, and >12 months from completion of chemotherapy or radiation.

    3. a. Participants (>18 years) with gastrointestinal (gastroesophageal, pancreatic, small bowel, colon, anal) solid tumors, breast, or prostate cancers who received myelosuppressive chemotherapy within 60 days prior to initial or booster COVID vaccination, or who started on chemotherapy within 60 days after the initial or booster COVID vaccination; or b. Adult participants (>18 years) not receiving chemotherapy at the time of initial or booster COVID vaccination, but who were on non-immunosuppressive treatments (endocrine therapy, treatment with tyrosine kinase inhibitor or antiHER-2 therapy); or c. Adult participants > 18 years either: (i) with no history of cancer or (ii) prior history of non-metastatic solid cancer invasive cancer treated with a curative intent, without evidence of disease recurrence, and >12 months from completion of chemotherapy or radiation.
    4. a. Participants in groups A and B who have a planned COVID vaccination within the next 90 days of study enrollment with any FDA approved vaccine, or previous COVID vaccination within 90 days from study enrollment are eligible provided they meet all other above eligibility criteria; or b. Participants in group C who have planned COVID vaccination within the next 90 days of study enrollment with any FDA approved vaccine; or previous COVID vaccination within six months from study enrollment are eligible provided they meet all other above eligibility criteria

Exclusion Criteria:

  • Participants will be considered ineligible for enrollment with the following criteria:

    1. Participants currently on immunotherapy
    2. Participants with documented COVID 19 infection within < 6 months from study enrollment
    3. Prior history of autoimmune disorder and are currently on immunosuppressive therapy or have received immunosuppressive therapy within the last 6-12 months prior to enrollment
    4. No planned and no prior COVID vaccination

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Group A will consist of 50 participants with a diagnosis of one of the following cancers: breast, colorectal, or prostate cancers who received myelosuppressive cytotoxic chemotherapy at the time of COVID vaccination, or who received chemotherapy within 30 days prior to the initial or booster vaccination, or who started on chemotherapy within 30 days after the initial or booster COVID vaccination. Cytotoxic chemotherapy can be given either in the neoadjuvant/adjuvant setting or metastatic setting.
Other: COVID antibody titers in the blood
COVID antibody titers will be quantitatively assessed at baseline, 8 weeks and approximately 6, 9, and 12 months from date of study enrollment.

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
Seroprotection rate
