Outcome Measures

Primary Outcomes (2)

  • Identify a Feasible Schedule of Vaccination Relative to SoC Neoadjuvant Chemotherapy When the Chemovax Are Administered Concurrently.

    Number of participants with sufficiently high anti-P10s immunoglobulin-G response Feasibility will be evaluated in terms of 1. Generation of a sufficiently high anti-P10s immunoglobulin-G response 2. Safety and tolerability of the combination of vaccine and chemotherapy

    At the time of definitive surgery (4-8 weeks after chemo, which is between Week 22 and Week 25)

  • Determine the pCR Rate

    The patient-level primary outcome for this objective is pathological Complete Response (pCR), which is binary yes/no, and the study-level endpoint for this outcome is the rate of pCR, i.e. the percentage of patients that achieved pCR=yes. The patient is assessed at the time of surgery for whether they achieved pCR=yes. They have to do the surgery in order to obtain the tissue samples on which they do their pCR assessment. Pathological Complete Response is defined as the absence of any residual invasive cancer on hematoxylin and eosin evaluation of the resected breast specimen and all sampled ipsilateral lymph nodes following completion of neoadjuvant systemic therapy (i.e., ypT0N0 or ypTisN0 in the AJCC staging system for staging solid tumors in the neoadjuvant setting that was described in a 2014 FDA Guidance for Industry).

    At the time of definitive surgery (4-8 weeks after chemo, which is between Week 22 and Week 25)

Secondary Outcomes (4)

  • P10s-MAP-Reactive Immunoglobulin Titers

    Week 1 through Week 70

  • Activation Profiles of NK Cells: Pre-Immune and Post-Immune CD16

    Week 1 through Week 70

  • Activation Profiles of NK Cells: Pre-Immune and Post-Immune CD69

    Week 1 through Week 70

  • Activation Profiles of NK Cells: Pre-Immune and Post-Immune NKp46

    Week 1 through Week 70

  • Active infection requiring treatment with antibiotics.
  • Existing diagnosis or history of organic brain syndrome that might preclude participation in the full protocol.
  • Existing diagnosis or history of significant impairment of basal cognitive function that might preclude participation in the full protocol.
  • Other current malignancies. Subjects with prior history at any time of any in situ cancer, including lobular carcinoma of the breast in situ, cervical cancer in situ, atypical melanocytic hyperplasia or Clark I melanoma in situ or basal or squamous skin cancer are eligible, provided they are disease-free at the time of registration. Subjects with other malignancies are eligible if they have been continuously disease free for ≥ 5 years prior to the time of registration.
  • Active autoimmune disorders or conditions of immunosuppression; Existing diagnosis or history of autoimmune disorders or conditions of immunosuppression that have been in remission for less than 6 months
  • Treatment with corticosteroids, including oral steroids (i.e. prednisone, dexamethasone \[except when used as an antiemetic in SoC therapy\]), continuous use of topical steroid creams or ointments or any steroid-containing inhalers. Subjects who discontinue the use of these classes of medication for at least 6 weeks prior to registration are eligible if, in the judgment of the treating physician, the subject is not likely to require these classes of drugs during the treatment period. Replacement doses of steroids for subjects with adrenal insufficiency are allowed.
  • Pregnancy or breastfeeding (due to the unknown effects of peptide/mimotope vaccines on a fetus or infant). Women of childbearing potential must have a negative urine pregnancy test within 72 hours prior to starting week 1 and must be counseled to use an accepted and effective method of contraception (including abstinence) while on treatment and for a period of 18 months after completing or discontinuing treatment. Accepted methods of contraception include tubal ligation, oral contraceptives, barrier methods, IUDs, and abstinence.
  • Any other significant medical or psychiatric conditions, which, in the opinion of the enrolling investigator, may interfere with consent or compliance of the treatment regimen.
  • Enrollment in any other clinical trial using investigational drug products or devices prior to first post-surgery study lab. Concurrent enrollment in observational studies is allowed.

Model Details: This combined Phase I/II feasibility-and-efficacy study will have three parts. Part 1 will be a Phase I evaluation of the safety, tolerability, and feasibility of the Chemovax to assess the timing of vaccination relative to chemotherapy. Five different Chemovax schedules (Schedule A, B, C, D, and E) will be sequentially evaluated. Once such a feasible schedule is identified, the study will proceed with its second and third parts. Part 2 (primary efficacy) and Part 3 (expanded efficacy) will respectively constitute Stages 1 and 2 of the Phase II primary-efficacy evaluation of Chemovax using a Simon optimal two-stage design.
