Phase II Trial of Sequential Consolidation With Pembrolizumab Followed by Nab-paclitaxel

Study Overview
=================
Brief Summary
-----------------
The purpose of this research study is to test the effectiveness of three treatment arms that are designed to improve survival in patients with non-small cell lung cancer. Eligible subjects could be randomized to four (4) cycles of chemotherapy followed by immunotherapy, or immunotherapy followed by chemotherapy, or four cycles of chemotherapy plus immunotherapy.

Detailed Description
-----------------
This open-label, three-arm, non-comparative randomized phase II study is designed to evaluate three different sequences of double-consolidation with the humanized monoclonal antibody targeted against cell surface receptor programmed cell death-1 (PD-1), pembrolizumab, and nab-paclitaxel in patients with advanced Non small cell lung cancer post induction chemotherapy. While the goal of each arm is to guarantee exposure to each of these two agents to patients who have not progressed post induction chemotherapy, they do so with different sequence. In ARMs A and B, consolidation is sequential, with either pembrolizumab followed by nab-paclitaxel (ARM A), or nab-paclitaxel followed by pembrolizumab (ARM B). In ARM C, consolidation is concurrent, with the two agents administered concurrently. As of July 24, ARMs B and C are closed, and no patients will be enrolled on this study. ARM A remains open to enrollment.

Eligibility Criteria
-----------------
Inclusion Criteria: Be willing and able to provide written informed consent for this trial Be greater than or equal to 18 years of age on day of signing consent Eastern Cooperative Oncology Group Performance Status less than or equal to 1 Histologically or cytologically confirmed confirmed stage IV (metastatic) non small cell lung cancer as defined by American Joint Committee on Cancer (AJCC). Recurrent but not metastatic disease is allowed if deemed incurable. Has completed or scheduled to begin 4-6 cycles of platinum based induction chemotherapy that does not include a taxane Induction may contain, but is not require to contain bevacizumab or cetuximab. Induction with a platinum doublet plus another biologic agent will be allowed following review by the University of North Carolina principal investigator that thee is no additional risk to the subject NOTE: Evaluable disease is not required for study entry (patients with complete response or response sufficient to preclude measurable lesions are not excluded; such patients will be evaluated for progression free survival and overall survival, but not response) Demonstrate adequate organ function (defined in protocol). All screening labs should be performed within 14 days of treatment initiation. Recovered from all reversible toxicities related to their previous treatment (other than alopecia) less than or equal to grade 1 or baseline; exceptions to this criteria may be allowed at the discretion of the overall principal investigator for toxicities that are not expected to be exacerbated by pembrolizumab or nab paclitaxel Patients with brain metastases may participate if they have undergone appropriate treatment for the lesion)s), are at least two weeks post treatment without evidence for post-treatment progression, have no significant neurologic symptoms, and no longer require steroids for the reason of brain metastases Female subject of childbearing potential should have a negative urine or serum pregnancy 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 subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for greater than 1 year. The two birth control methods can be two barrier methods or a barrier method plus a hormonal method to prevent pregnancy. Subjects should start using birth control from study Visit 1 throughout the study period up to 120 days after the last dose of study therapy. Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Survival | Overall survival is defined as the time from day 1 of treatment to death from any cause. Median overall survival was calculated for each arm. | Up to 60 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival (PFS) | PFS is defined as the time from first day of treatment until disease progression as defined by the response evaluation criteria in solid tumors (RECIST 1.1) and and Immune Related Response Criteria (irRC), or death from any cause death or progression. RECIST 1.1 Progressive Disease (PD): >= 20% increase in the sum of the LD of the target lesions, Stable Disease (SD) Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, Nonprogressive disease (NPD): No measurable disease at the entrance of the study or otherwise non measurable disease will be assessed for progression. irRC Progressive Disease (irPD), ≥20% increase in tumor burden and minimum 5 mm absolute increase in compared to nadir; for no new non-target or (irNN) and where irPR or irPD are confirmed by a repeat, consecutive assessment no less than 4 weeks later. | Up to 60 months | 
| Overall Rates of Response (ORR) | ORR is defined as the number of subjects with complete response + partial response based on RECIST 1.1 and irRC criteria. RECIST 1.1 Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): >=30% decrease in the sum of the longest diameter (LD) of target lesions. irRC Complete Response (irCR): Disappearance of all lesions, no new lesions, lymph nodes < 10 mm in short axis, Partial Response (irPR): ≥30% decrease in the sum of target lesions and non-target lesions are irNN. | 6 months | 
| Rates of Response in Arm A and Arm B | Rates of Response is defined percent tumor size reduction based RECIST1.1 and irRC criteria (the latter if applicable) after each component of therapy in Arm A and Arm B. | 6 months | 
| Toxicity Profile | The toxicity profile is classified and defined by both provider and the participants reported outcomes. Clinician assessed toxicity will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, version 4.0) Participants assessed toxicity will be classified based on the Patient-Reported Outcome version of the CTCAE (PRO-CTCAE). Adverse events occurring in greater than two patients or any grade 3 toxicity were included. | 6 months | 
| Quality of Life (QOL) End of Treatment | Changes in QOL score for each subject are defined as the difference between the baseline, and at end of treatment. QOL will be evaluated using The Functional Assessment of Cancer Therapy-Lung (FACT-Lung) scale at baseline and the end of treatment. The FACT-L is the FACT-G and a lung cancer-specific (LCS) subscale given at baseline and end of treatment. The FACT-G is a 27-item measure of general QOL assessing function in 4 domains: physical well-being, social-family well-being, emotional well-being, and functional well-being. Items are rated by patients on a Likert scale from 0 to 4. Higher scores represent better QOL. | Baseline to End of Treatment (up to 210 Days) | 
| Quality of Life (QOL) 7 Weeks | Changes in QOL score for each subject are defined as the difference between the baseline, and at 7 weeks. QOL will be evaluated using The Functional Assessment of Cancer Therapy-Lung (FACT-Lung) scale at baseline and 7 weeks. The FACT-L is the FACT-G and a lung cancer-specific (LCS) subscale given at baseline and at end of treatment. The FACT-G is a 27-item measure of general QOL assessing function in 4 domains: physical well-being, social-family well-being, emotional well-being, and functional well-being. Items are rated by patients on a Likert scale from 0 to 4. Higher scores represent better QOL. | Baseline to 7 weeks (40-50 Days) |
