Immune Response to Antigens

Overview

About this study

The purpose of this study is to sequence patient germline and tumor samples, and nominate top neoantigen candidates using an in-house developed bioinformatics pipeline, and to validate the neoantigen candidates by laboratory assays using patient peripheral blood immune cells or serum.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Age ≥ 18 years.

For cancer patients:

  • 10 samples from each of the following cancers: breast, bladder, cervical, colorectal, head and neck, liver, lung, kidney, skin, stomach, as well as Hodgkin lymphoma.
  • Stages II, III, or IV disease.
  • Provide written informed consent.
  • Willingness to provide blood samples for neoantigen validation and T-cell activity assays.
  • Patients will either have the archived frozen tissue or consented to give fresh tissue biopsy and blood samples to the study.  Alternatively, if tumor sequence data is already available from 13-000942 and 14-004094-52, that data can be used in the place of a newly collected or archived frozen sample.  However, fresh blood must still be collected.

Exclusion Criteria:

  • Immunocompromised patients including patients known to be HIV positive
  • Patients receiving systemic steroid therapy or any other immunosuppressive therapy ≤ 30 days prior to registration. NOTE: Inhaled steroids, low-dose corticosteroids (e.g. equivalent to or less than oral prednisone 10 mg daily), and steroid use for primary prevention of nausea per institutional guidelines are allowed.
  • Patients who received radiation therapies within 6 months of tissue/blood collections.
  • Recent chemotherapy is not an exclusion criterion.
  • Pregnant women will not be allowed to enroll on this study.
