Testing the Addition of Targeted Radiation Therapy to Surgery and the Usual Chemotherapy Treatment (Pemetrexed and Cisplatin [or Carboplatin]) for Stage I-IIIA Malignant Pleural Mesothelioma

Phase III Randomized Trial of Pleurectomy/Decortication Plus Systemic Therapy With or Without Adjuvant Hemithoracic Intensity-Modulated Pleural Radiation Therapy (IMPRINT) for Malignant Pleural Mesothelioma (MPM)

This trial studies how well the addition of targeted radiation therapy to surgery and the usual chemotherapy treatment works for the treatment of stage I-IIIA malignant pleural mesothelioma. Targeted radiation therapy such as intensity-modulated radiation therapy or pencil beam scanning uses high energy rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as pemetrexed, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving targeted radiation therapy in addition to surgery and chemotherapy may work better than surgery and chemotherapy alone for the treatment of malignant pleural mesothelioma.

Detailed Description

PRIMARY OBJECTIVE:

I. To detect an improvement in overall survival with the addition of adjuvant hemithoracic intensity-modulated pleural radiation therapy (IMPRINT) to surgery and chemotherapy compared to surgery and chemotherapy alone.

SECONDARY OBJECTIVES:

I. To determine local failure-free survival, distant-metastases-free survival, and progression-free survival with the addition of adjuvant hemithoracic IMPRINT to surgery and chemotherapy compared to surgery and chemotherapy alone.

II. To evaluate the treatment-related toxicities in both arms per Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0.

III. To detect a clinically meaningful 10-point change in global health status mean scores at 9 months after randomization with the addition of adjuvant IMPRINT as compared to surgery and chemotherapy alone.

EXPLORATORY OBJECTIVES:

I. To evaluate the degree of under-staging, concordant and upstaging between centrally-reviewed clinical staging (based on positron emission tomography [PET], computed tomography [CT] and/or magnetic resonance imaging [MRI]) and pathologic staging.

II. To identify immunologic and pathologic biomarkers as predictors of response and potential targets for future combination trials.

III. To determine the magnitude of radiation dose escalation to gross residual disease based on combined modality imaging and associated local control rates with dose-painting intensity-modulated radiation therapy (IMRT).

IV. To determine the rate of R0/R1 and R2 resections, and type of procedures (extended pleurectomy/decortication [P/D], P/D and partial pleurectomy).

V. To evaluate the trajectory of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-Q30) and lung cancer specific module (LC13) symptoms in patients treated with IMPRINT by comparing the proportion of patients who respond with "quite a bit" or "very much" LC13 symptoms at 9-12 months post-randomization compared to at 3 months post-randomization.

VI. To evaluate changes in health-related quality of life, functional domains, and symptoms over time with the addition of adjuvant IMPRINT as compared to surgery and chemotherapy alone.

OUTLINE:

STEP 1: Patients undergo P/D then within 4 to 8 weeks receive pemetrexed intravenously (IV) over 10 minutes and cisplatin or carboplatin IV over 60 minutes on day 1. Patients may instead receive pemetrexed IV over 10 minutes and cisplatin or carboplatin IV over 60 minutes on day 1 then undergo P/D within 4 to 8 weeks after chemotherapy. The order of surgery and chemotherapy is at the discretion of the treating physician.

STEP 2: Within 4 to 8 weeks from the end of Step 1 treatment, patients are randomized to 1 of 2 arms.

ARM I: Patients receive no treatment.

ARM II: Patients undergo 25-28 fractions IMRT or pencil beam scanning (PBS) proton therapy 5 days per week over 6 weeks.

After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival (OS)	Will compare the distributions of OS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of OS for each arm will be estimated using the Kaplan-Meier method. The associated 90% confidence interval (CI) will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios will be estimated using a stratified Cox regression model.	From the date of randomization and the date of death due to any cause, assessed up to 5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Local-failure-free survival (LFFS)	Will compare the distributions of LFFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of LFFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for LFFS will be estimated using a stratified Cox regression model.	From randomization to local disease progression or death due to any cause, whichever occurs first, assessed up to 5 years
Distant-metastases-free survival (DMFS)	Will compare the distributions of DMFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of DMFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for PFS will be estimated using a stratified Cox regression model.	From randomization to distant metastases or death due to any cause, whichever occurs first, assessed up to 5 years
Progression-free survival (PFS)	Will compare the distributions of PFS between treatment arms using a one-sided stratified log-rank test (using stratification factors as strata). The rates at various timepoints (e.g., every 6 months after randomization) and medians of PFS for each arm will be estimated using the Kaplan-Meier method (1958). The associated 95% CI will be calculated using Greenwood?s formula and based on a log-log transformation applied on the survival function. Hazard ratios for PFS will be estimated using a stratified Cox regression model.	From randomization to any documented progression or death due to any cause, whichever occurs first, assessed up to 5 years
Incidence of treatment-related toxicity	Adverse events (AEs) will be graded with Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. All adverse events, adverse events leading to withdrawal, interruption or modification of protocol treatment, grade >= 3 adverse events, and serious adverse events will be summarized. Deaths and cause of death will be summarized. The rate of treatment-related adverse events will be reported with the frequency and severity (e.g., type, grade, and attribution) by arm.	Up to 5 years
Quality of Life (QOL)/patient-reported Outcome (PRO)	Measured by European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaires.	Up to 5 years

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Degree of under-staging, concordant and upstaging between centrally-reviewed clinical staging and pathologic staging	For each subject, the centrally-reviewed clinical staging (based on positron emission tomography, computed tomography and/or magnetic resonance imaging) will be compared with pathologic staging to determine whether it is under-staging (clinical staging is more extensive than pathologic staging), concordant (clinical staging is same as pathologic staging), or upstaging (clinical staging is less extensive than pathologic staging). The proportion of under-staging, concordant and upstaging, along with the associated 95% confidence intervals, will be reported.	Up to 5 years
Association between radiation dose to gross residual disease and local control	Gross residual disease and local failure will be analyzed as competing risk data (death without gross residual disease or death without local failure as the respective competing event). Association between radiation dose to gross residual disease and local failure will be evaluated similarly in multivariable analyses using Fine-Gray regression model.	Up to 5 years
Rate of R0/R1 and R2 resections, by type of procedures (extended pleurectomy/decortication (P/D), P/D and partial pleurectomy)	Proportions of R0/R1 and R2 resections, by type of procedures (extended pleurectomy/decortication (P/D), P/D and partial pleurectomy), along with 95% confidence intervals, will be reported.	Up to 5 years
