Study Description

Brief Summary:

This phase II trial studies how well pembrolizumab given every 12 weeks works compared to every 3 weeks in treating patients with non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab every 12 weeks may provide similar disease control with fewer treatments for patients with non-small cell lung cancer when compared to every 3 weeks. Demonstrating that 12 week dosing is as effective as 3 week dosing may also have a significant impact when considering the cost required for these medications.

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate the 1-year progression-free survival rate with 200mg pembrolizumab administered every 3 weeks compared to 200mg pembrolizumab administered every 12 weeks.

SECONDARY OBJECTIVES:

I. To assess overall survival between the two treatment groups. II. To assess the serious adverse event profiles between the two treatment groups.

EXPLORATORY OBJECTIVES:

I. To evaluate circulating biomarkers of treatment response and resistance. II. To characterize fecal microbiotic profile and to correlate those results with tumor characteristics and antitumor immune responses.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive pembrolizumab intravenously (IV) over 30 minutes every 3 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive pembrolizumab IV over 30 minutes every 12 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, and then every 12 weeks for at least 12 months.

Outcome Measures

Primary Outcome Measures :

1. 1-year progression-free survival (PFS) [ Time Frame: Baseline to 12 months ]
   Measured using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

Secondary Outcome Measures :

1. Overall survival [ Time Frame: Up to 12 months after treatment completion ]
   Defined as the number of months between Loading Phase enrollment and death from any cause. Analysis of overall survival between the two treatment groups will be carried forth using a log-rank test accounting for the stratification factors, including other known variables such as PD-L1 tumor proportion score, line of therapy, histology, mutation profile.
2. Incidence of adverse events [ Time Frame: Up to 12 months ]
   Assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Will be assessed through the evaluation of grade 3 or higher toxicities deemed possibly related to treatment. Both efficacy and toxicity rates will be estimated using simple relative frequencies. The corresponding 95% confidence intervals for the estimated probabilities will be computed.

Other Outcome Measures:

1. Cox regression models in terms of treatment resistance [ Time Frame: Up to 12 months ]
   Circulating biomarkers of treatment response and resistance
2. Length of time on treatment [ Time Frame: Up to 12 months ]
   Length of time on treatment as a time varying covariate will be carried out using Cox regression models.

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

• Have an Eastern Cooperative Oncology Group (ECOG) performance status of =< 2 at the time of study treatment initiation.
• Have pathologically confirmed diagnosis of non-small cell lung cancer (NSCLC). Mixed small cell lung cancer (SCLC) histology is not allowed.
• Must be eligible for treatment with pembrolizumab as standard of care (up to third line).
• Absolute neutrophil count (ANC) >= 1.5 x 10^9/L.
• Platelets >= 100 x 10^9/L.
• Hemoglobin >= 9 g/dL.
• Plasma creatinine =< 1.5 x institution upper limit of normal (ULN) or estimated glomerular filtration rate (GFR) (measured or calculated with Cockcroft and Gault formula) > 45 ml/min.
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 3 x ULN (ALT and AST =< 5 x ULN is acceptable if liver metastases are present).
• Total plasma bilirubin =< 1.5 x ULN. For patients with well documented Gilbert?s syndrome, total bilirubin =< 3 x ULN with direct bilirubin within normal range.
• Must have demonstrated complete response, partial response by Response Evaluation Criteria in Solid Tumors (RECIST) or stable disease if > 5% but less than 30% decrease from baseline total tumor burden (target lesions) to pembrolizumab at the time of randomization for study treatment.Patients with new brain metastasis isolated in the brain while on pembrolizumab monotherapy will be eligible as long as extracranial disease control fulfills the criteria otherwise (i.e. this will not be considered as disease progression for the purpose of this study).
• Must have received at least 6 months of pembrolizumab monotherapy treatment (but no more than 15 months total duration, including treatment in combination with chemotherapy prior to maintenance phase) prior to start of protocol-assigned treatment.
• Participants of child-bearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
• Participant or legal representative must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure.
