Clinical Trial Summary

The purpose of this study is to find out if treatment with NEO-PV-01 in combination with pembrolizumab and chemotherapy (pembrolizumab/chemotherapy) is safe and useful for patients with lung cancer. The study also will assess if the NEO-PV-01 vaccine, when given together with pembrolizumab and chemotherapy, can improve your response compared with pembrolizumab and chemotherapy treatment alone. All eligible patients will receive NEO-PV-01 + Adjuvant, pembrolizumab and chemotherapy while on this trial.

Description:

This clinical trial will enroll patients with advanced or metastatic nonsquamous non-small cell lung carcinoma not having received treatment for metastatic disease. The five agents being used in this study are:

• A new, investigational, personalized cancer vaccine called "NEO-PV-01"

• Poly-ICLC (Hiltonol), an investigational adjuvant that is used to help stimulate the immune system

• A cancer drug called pembrolizumab (KEYTRUDA®)

• A chemotherapy called pemetrexed (ALIMPTA®)

• A chemotherapy called carboplatin

Both NEO-PV-01 and pembrolizumab are considered immunotherapies and work using the immune system to fight cancer. NEO-PV-01 is a custom made vaccine for you that is based on the specific targets on your cancer. Poly-ICLC is an adjuvant that helps stimulate the immune system and make the vaccine, NEO-PV-01, more effective.

Pembrolizumab helps T-cells, a certain type of immune cell, that recognize these targets to reach and attack your cancer. Pembrolizumab, which is approved in the USA and some other countries, is available by prescription to treat several different cancers, including the type of cancer that you have. Recently, the FDA also approved the combination of Pembrolizumab with chemotherapy for the treatment of your type of lung cancer. This combination works better than each of the drugs on their own.

The purpose of this study is to find out if treatment with NEO-PV-01 in combination with pembrolizumab and chemotherapy is safe and useful for patients with lung cancer. The study also will assess if the NEO-PV-01 vaccine, when given together with pembrolizumab and chemotherapy, can improve your immune response compared with pembrolizumab and chemotherapy treatment alone. The side effects of NEO-PV-01, pembrolizumab, and chemotherapy will be monitored and additional research tests will be done to assess your immune response to your cancer.

• Screening laboratory values must meet the following criteria and should be obtained within 30 days (or 45 days if a biopsy is repeated) prior to study treatment:

1. White blood cell (WBC) count = 3 × 10e3/µL

2. Absolute neutrophil count (ANC) = 1.5 × 10e3/µL

3. Platelet count = 100 × 10e3/µL

4. Hemoglobin > 9 g/dL

7. Total bilirubin = 1.5 × ULN (except in patients with Gilbert Syndrome who can have total bilirubin < 3.0 mg/dL). Direct bilirubin = ULN for patients with total bilirubin levels >1.5 × ULN.

8. International Normalized Ratio (INR) or Prothrombin Time (PT) =1.5 × ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

9. Activated Partial Thromboplastin Time (aPTT) =1.5 × ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

• Female patients of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

• Female patients of childbearing potential must be willing to use an adequate method of contraception as outlined in Section 6.4.5.3, for the course of the study through 120 days after the last dose of study medication. Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the patient.

• Male patients of childbearing potential must agree to use an adequate method of contraception as outlined in Section 6.4.5.3, starting with the first dose of study therapy through 120 days after the last dose of study therapy. Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the patient.

Exclusion Criteria:

• Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of first dose of treatment.

• Received any systemic therapy for cancer treatment including immunotherapeutic agents such as anti-PD1 or anti-PD-L1 antibody therapy.

• Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (ie, = Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

• Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 30 days prior to study Day 1 or who has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to a previously administered agent.

1. Note: Subjects with = Grade 2 neuropathy or = Grade 2 alopecia are an exception to this criterion and may qualify for the study.

2. Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy

• Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. The use of physiologic doses of corticosteroids may be approved after consultation with the Sponsor.
