Clinical Trial Summary

This study evaluates gut microbiome and functional status as modifiable biomarkers in predicting immunotherapy response and toxicity in patients with stage IV non-squamous non-small cell lung cancer receiving pembrolizumab alone or in combination with pemetrexed and carboplatin on the INSIGNIA trial. The goal of this study is to estimate the extent to which future interventions that seek to rationally modify the gut microbiome and/or functional status can improve outcomes.

Description:

PRIMARY OBJECTIVE:

I. To quantify the performance of two modifiable biomarkers -- the microbiome and functional status - to use as predictive and/or prognostic indicators of clinical benefit (overall survival, progression-free survival) in lung cancer patients who receive randomized treatment combinations prescribed by the INSIGNA protocol.

SECONDARY OBJECTIVE:

I. To quantify the predictive power of two modifiable biomarkers - the microbiome and functional status -- for the development of immune-related adverse events (irAEs).

OUTLINE:

Patients receive treatment by their treating physician as described in the INSIGNA protocol based on their designated treatment arm. Patients then undergo stool sample collection, complete questionnaires and functional status assessments, such as short physical performance battery over 10 minutes and 6 minute walk test, at baseline, days 40 (cycle 3), day 80 (cycle 5), day 180 (cycle 10) and end of treatment (up to 2 years).

• Methotrexate (MTX) given in low doses for non-malignant conditions with last dose at least 14 days prior to date of registration will be allowed. Other low-dose chemotherapeutics for non-malignant conditions will be considered, but review by the study chair is required.

• Patient with known EGFR mutations (except exon 20 insertion), BRAF mutation (V600) or ALK or ROS1 translocations that can be treated with oral tyrosine kinase inhibitors are excluded.

• Patients with symptomatic brain metastases are excluded. Patients with treated or asymptomatic brain metastases are eligible if off steroids for at least 14 days. Anticonvulsants are allowed.

• Patients with active malignancy within the last 2 years are excluded (adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years are eligible).

• Patients must not have known pre-existing and clinically active interstitial lung disease.

• Patients must not have significant gastrointestinal disorders with diarrhea as a major symptom (e.g. Crohn's disease, malabsorption, etc.)

• Patients must not have history of auto-immune condition requiring ongoing or intermittent systemic treatment.

• Patients must not have history of clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure New York Heart Association (NYHA) classification of 3, unstable angina or poorly controlled arrhythmia, or myocardial infarction within 6 months.

• Patients must not have any other concomitant serious illness or organ system dysfunction that in the opinion of the investigator would either compromise patient safety or interfere with the evaluation of the safety of the study drug.

• Patients must not plan to receive any other investigational agents during the course of therapy.

• Women must not be pregnant or breast-feeding due to potential harm to the fetus or infant from cytotoxic chemotherapy and the unknown risk of pembrolizumab.

• All females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy.

• A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Microbiome alpha diversity	Diversity will be calculated and stratified as described above, and the stratification will be used in a Kaplan-Meier survival curve to measure time to event, where the event is development of an immune related adverse events (irAEs).	Baseline up to 2 years
Other	Relative abundance of the phylum Bacteroidetes	The relative abundance of Bacteroidetes will be used as a continuous variable in a Cox proportional hazards model where the event is development of an irAE as described above. Uni-and multi-variate tests will be performed controlling for the effects of age, body mass index and smoking status. Additional covariates will be explored in an exploratory fashion.	Baseline up to 2 years
Other	Predictive power of the 6MWT and SPPB	Will be quantified for the development in irAEs. Diversity will be calculated and stratified as described above, and the stratification will be used in a Kaplan-Meier survival curve to measure time to event, where the event is development of an irAE.	Baseline up to 2 years
Other	Microbiome and functional status to tumor biomarkers	Will be compared. Will show significant associations with the outcomes of interest and particularly with markers of the immune system and inflammation.	Baseline up to 2 years
Other	Functional trajectory analysis	Linear mixed-effects models will be used to characterize functional status trajectories through the course of treatment. This model allows for the estimation of intercept and slopes for each patient and group. Participants' functional status scores will be modeled using a segmented mixed model with random change points to estimate when functional status scores change during treatment. Will calculate Somers' Dxy and the c-statistic, in the case of the Cox regression models, and area under receiver-operating characteristic curves in the case of the logistic regression, to identify the model with the highest prediction accuracy in the hold-out data. Co-linearity would be indicated by variables with alternating inclusion in the model.	Baseline up to 2 years
Primary	Performance of the microbiome as predictive indicator of clinical benefit (overall survival, progression free survival)	Count tables derived from the Kraken/Bracken pipeline output will be used to calculate the diversity metric Simpson's Index to quantify the number of species and evenness of the stool microbiome samples. Diversity will be binarized into high versus (vs) low at the median value, and then this variable used to stratify a Kaplan-Meier survival curve (predictive indicator). This will be further stratified by first-line treatment type (Arms A&B vs Arm C) to evaluate microbe diversity predicts response by treatment (prognostic indicator).	Baseline up to 2 years
Primary	Performance of the microbiome as prognostic indicator of clinical benefit (overall survival, progression free survival)	The calculation will follow the methods described above but performed within treatment type (Arms A&B separately from Arm C). The interpretation will rely on the comparison between treatments. For example, if a highly diverse microbiome is significantly predictive of overall survival in Arms A&B but not within Arm C, then it would be a prognostic indicator of outcome in the context of treatment with ICIs. If it is predictive of response in both treatment groups then we will be unable to discern whether it is prognostic.	Baseline up to 2 years
Primary	Performance of functional status as predictive indicator of clinical benefit (progression free survival)	Functional status will be measured using a variety of methods including the 6 minute walk test (6MWT), for which they will be stratified by the median distance walked. This stratification will be used in a Kaplan-Meier survival curve to measure time to event, where the event is progression free survival.	Baseline up to 2 years
Primary	Performance of functional status as prognostic indicator of clinical benefit (progression free survival)	Physical activity will also be measured using a Short Physical Performance Battery (SPPB). Patients will be stratified by =< 7 and > 7 via grouping those assigned to the "very low physical function (0-3)" and "low physical function (4-6)" groups together, and the "moderate physical function (7-9)" and "high physical function (10-12)" groups together, assuming roughly equal split in the populations assigned by the stratification.	Baseline up to 2 years
