Cancer Peptides Plus GM-CSF and Adjuvant in Breast Cancer

NCT04270149

Description:

This is a phase I study looking at the safety of cancer peptides combined with adjuvant and GM-CSF in subjects with estrogen receptor (ESR) positive breast cancer. The primary objective of the study is to determine the safety of of the peptide vaccine. The secondary objective is to evaluate the immune response to the vaccine. The peptides used in this vaccine are derived from the estrogen receptor and are combined with the adjuvant Montanide ISA and GM-CSF to enhance their immune response. A peptide vaccine of these peptides may improve outcomes of patients with endocrine resistant breast cancer.

Eligibility Criteria

        Inclusion Criteria:

          -  Patients with histologically confirmed, resected, breast cancer with one of the
             following characteristics:

        pT3 or greater T stage with any N stage and M0 pTxN+M0 (i.e., N1,2 or 3)

          -  HLA A0201+ and tumor is ER+

          -  Patients must have completed any standard chemotherapy recommended by their physician.
             There must be at least 4 weeks from their last dose of chemotherapy (or surgery if no
             chemotherapy was given) prior to the first dose of study vaccine. There should be no
             more than 2 years from the time of completion of no maximum amount of time since a
             person has completed any chemotherapy, surgery or HER2 targeted therapy. Ongoing
             endocrine therapies are permitted as long as they have been administered for at least
             3 months prior to study enrollment.

          -  Age ≥ 18 years.

          -  Heme: WBC ≥ 3000/microliter, hemoglobin ≥ 9 g/dL, platelets ≥ 80,000/microliter.

          -  Adequate, renal and hepatic function with serum creatinine < 1.5 mg/dL, bilirubin <
             1.5 mg/dL (except a bilirubin of <2.0 will be permitted for patents with Gilbert's
             syndrome), SGOT/SGPT < 2 x upper limit of normal.

          -  Ability to understand and provide signed informed consent that fulfills Institutional
             Review Board's guidelines.

        Exclusion Criteria:

          -  Subjects with concurrent chemotherapy, radiation therapy, or immunotherapy are
             excluded. There must be at least 4 weeks between these prior therapy and study
             treatment. Subjects must have recovered from all acute toxicities from prior
             treatment. Peripheral neuropathy grade 1 due to prior therapy will be permitted.

          -  Subjects may not have history of distant metastases.

          -  Subjects with a history of autoimmune disease, such as but not restricted to,
             inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis,
             scleroderma, or multiple sclerosis. A positive ANA (anti-nuclear antibody) test
             without other evidence of autoimmune disease will not exclude a subject for this
             study. A prior history of autoimmune hypothyroidism will not exclude a subject.

          -  Subjects with serious intercurrent chronic or acute illness, such as cardiac disease,
             (NYHA class III or IV), hepatic disease, or other illness considered by the Principal
             Investigator as unwarranted high risk for investigational drug treatment.

          -  Subjects with a medical or psychological impediment to probable compliance with the

          -  Concurrent (or within the last 5 years) second malignancy other than non-melanoma skin
             cancer, cervical carcinoma in situ, controlled carcinoma in situ of the cervix, or
             controlled superficial bladder cancer.

          -  Presence of an active acute or chronic infection including: an urinary tract
             infection, HIV (as determined by ELISA and confirmed by Western Blot) or viral
             hepatitis (as determined by HBsAg and Hepatitis C serology). Subjects with HIV are
             excluded based on immuno-suppression, which may render them unable to respond to the
             vaccine; subjects with chronic hepatitis are excluded because of concern that
             hepatitis could be exacerbated by the injections.

          -  Subjects on steroid therapy (or other immuno-suppressives, such as azathioprine or
             cyclosporin A) are excluded on the basis of potential immune suppression. Subjects
             must have had 6 weeks of discontinuation of any steroid therapy (except that used as
             pre-medication for chemotherapy or contrast-enhanced studies) prior to enrollment.

          -  Subjects with allergies to any component of the vaccine

          -  Pregnant or nursing mothers.

          -  Subjects with acute or chronic skin disorders that will interfere with peptide
             injection into the skin of the extremities or subsequent assessment of potential skin
             reactions will be excluded.
