Inclusion Criteria:

  • Diagnosis of grade I-IIIA follicular lymphoma (pathology must be confirmed at DFCI/BWH)
  • Planned treatment with 4 weekly doses of rituximab.
  • No prior systemic therapy for follicular lymphoma; prior radiation with palliative or curative intent is allowed if radiation occurred more than 3 months prior to study entry

  • Age ≥ 18 years.
  • ECOG performance status < 2.
  • Participants must have normal organ and marrow function as defined below:

    • Hemoglobin > 9 gm/dl (ESAs or transfusion are not allowed) [greater than 8 gm/dl if there is lymphoma involvement of the bone marrow]
    • ANC > 1000 (greater than 750 if there is lymphoma involvement of the bone marrow)
    • Platelet count >100,000 (greater than 50,000 if there is lymphoma involvement of the bone marrow]
    • International normalized ratio (INR) or prothrombin time (PT) or activated partial thromboplastin time (aPTT) < 1.5 x ULN unless subject is on anticoagulation as long as PT or aPTT is within intended therapeutic range of anticoagulant used
    • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal (< 5 x ULN if there are hepatic metastases)
    • Creatinine < 1.5 x ULN or measured or calculated creatinine clearance (GFR can also be used in place of creatinine clearance) > 30 ml/min for subject with creatinine > 1.5 x institutional ULN
    • total bilirubin less than institutional 1.5 x ULN (or a direct bilirubin < ULN if total bilirubin is >1.5 x ULN)
  • The effects of NeoVax and poly-ICLC on the developing human fetus are unknown. For this reason, women of childbearing potential (WOCBP) must have a negative pregnancy test (serum) before entry onto the trial and within 7 days prior to start of study vaccination.

Approved contraceptive methods include for example; intra uterine device, diaphragm with spermicide, cervical cap with spermicide, male condoms, or female condom with spermicide. Spermicides alone are not an acceptable method of contraception. Male participants need to agree to use an adequate method of contraception

  • Participants must meet the following criteria (in addition to the above) to be eligible to proceed to receive vaccine treatment on the study:
  • At least 7 immunizing peptides can be designed
  • Continue to meet inclusion and exclusion criteria for Screening Registration (note: hepatitis B and hepatitis C serologies do not need to be repeated unless there is a clinical concern that an exposure has occurred since the screening phase).

Exclusion Criteria:

  • Recovered from all AEs due to rituximab to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy may be eligible. Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment

  • Concomitant therapy with immunosuppressive or immunomodulatory agents; chronic use of systemic corticosteroids at doses of 10 mg of prednisone (or equivalent) for indications other than treatment of follicular lymphoma is acceptable. Use of higher doses of corticosteroids after initial registration is acceptable if tapered to 10 mg of prednisone (or equivalent) or les at least 7 days prior to NeoVax administration so long as the corticosteroids were not administered for follicular lymphoma.

  • Any underlying medical condition, psychiatric condition or social situation that in the opinion of the investigator would compromise study administration as per protocol or compromise the assessment of AEs.
  • Pregnant women are excluded from this study because personalized neoantigen peptides and poly-ICLC are agents with unknown risks to the developing fetus. Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with personalized neoantigen peptides and poly-ICLC, nursing women are excluded from this study.

Outcomes

Primary Outcome Measures

Feasibility of Neovax following 4 weekly doses of rituximab assessed by the following
The proportion of all enrolled patients for whom sequencing and analysis leads to identification of at least 7 actionable peptides to initiate vaccine production and, of the patients who generate at least 7 actionable peptides, the proportion for whom the time from sample collection to vaccine availability is less than 12 weeks.

Secondary Outcome Measures

The proportion of participants who achieve an IFN-γ T cell response to one or more of the peptide pools
The induction of IFN-γ T-cell response will be based on ELISPOT assessments taken prior to vaccine administration and at week 16 from both peripheral blood draws and bone marrow biopsies. The proportion of patients who achieve more than 55 SFU/106 PBMC or 3 times their baseline level will be presented with a 90% exact binomial confidence interval. Based on a cohort of size 10, the confidence interval will be no wider than 0.55. It is possible that the maximal response will occur at a different sampling time point or will vary between participants. Thus, this time point may vary from week 16.
The proportion of participants who convert from PR to CR
The investigators will report the proportion of patients converting from SD to CR/PR or from PR to CR based upon Lugano criteria in a descriptive fashion.
The proportion of participants who convert from SD to PR/CR
The investigators will report the proportion of patients converting from SD to CR/PR or from SD to PR or CR based upon Lugano criteria in a descriptive fashion.
Best Objective Response
The investigators will report the best objective response (CR, PR, SD, or PD) based upon Lugano criteria in a descriptive fashion.
To describe the safety and tolerability of NeoVax following 4 weekly doses of rituximab in patient with previously untreated follicular lymphoma
The investigators will report toxicity in a descriptive fashion using CTCAE version 4.0

Brief Summary
This research study is studying a novel type of FL vaccine as a possible treatment for follicular lymphoma (FL). The agents involved in this study are: Rituximab Personalized NeoAntigen vaccine Poly-ICLC Pembrolizumab
Detailed Description
This research study is a Pilot Study, which is the first time investigators are examining the Personalized Neoantigen Vaccine (NeoVax) in patients diagnosed with follicular lymphoma. The FDA (the U.S. Food and Drug Administration) has not approved the Personalized Neoantigen Vaccine as a treatment for any disease. Patients will receive 4 weekly doses rituximab (a CD20 monoclonal antibody) during NeoVax manufacturing (see below). Patients who have stable disease or achieve a response with rituximab therapy will next receiving NeoVax alone (first 5 patients) or NeoVax in combination with pembrolizumab (a PD-1 monoclonal antibody). The purpose of this study is to determine if it is possible to make and safely administer a vaccine against FL by using information gained from specific genetic characteristics of the participant's own FL cells. The investigators plan to analyze the specific genetic characteristics of the participant's own FL cells and use that information to produce proteins that may help the participant's immune system recognize and fight FL cells. This vaccine has already been tested in clinical trials in patients with advanced melanoma (a type of skin cancer) and glioblastoma (a type of brain cancer). The current study will examine the ability of the vaccine to stimulate the participant's immune system when given at several different timepoints, and will examine the participant's blood cells for signs that the FL has changed or decreased. FL cells will be obtained from a tumor biopsy. The genetic material contained in the FL cells will be examined for the presence of tumor-specific mutations. This information will be used to prepare small protein fragments, which are called "peptides." The vaccine will consist of up to 20 of these peptides as well as a drug called Poly-ICLC. A peptide from the tetanus vaccine will also be included to boost the immune response. Poly-ICLC (also called Hiltonol) is an experimental "viral mimic" and an activator of immunity. Poly-ICLC binds proteins on the surface of certain immune cells to make it appear as if a virus is present. When the cells detect the vaccine, they think it is a virus and turn on the immune system. Poly-ICLC will be mixed with NeoAntigen peptides and administered as an injection given underneath the skin. Poly-ICLC is an investigational drug, meaning the FDA has not approved it as a treatment for any disease.
