Testing the Addition of a Type of Drug Called Immunotherapy to the Usual Chemotherapy Treatment for Non-small Cell Lung Cancer ALCHEMIST Chemo-IO Study


Brief description of study

This phase III ALCHEMIST trial compares the addition of pembrolizumab to usual chemotherapy versus usual chemotherapy for the treatment of stage IB, II, or IIIA non-small cell lung cancer that has been removed by surgery. 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. Drugs used in chemotherapy, such as cisplatin, pemetrexed, carboplatin, gemcitabine hydrochloride, and paclitaxel, 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. The purpose of this trial is to find out if the addition of pembrolizumab to usual chemotherapy is better or worse than usual chemotherapy alone for non-small cell lung cancer.

Detailed Study Description

PRIMARY OBJECTIVES:

I. To compare the disease free survival (DFS) and overall survival (OS) (dual primary endpoints) between combination MK-3475 (pembrolizumab) plus standard of care (Arm C) versus (vs.) standard of care (Arm A) in patients with stage IB-IIIA non-small cell lung cancer.

II. To compare the DFS and OS (dual primary endpoints) between sequential MK-3475 (pembrolizumab) following standard of care (Arm B) vs. standard of care (Arm A) followed by observation in patients with stage IB-IIIA non-small cell lung cancer.

SECONDARY OBJECTIVES:

I. To compare the DFS and OS between combination MK-3475 (pembrolizumab) with standard of care (Arm C) vs. sequential standard of care followed by MK-3475 (pembrolizumab) (Arm B) in patients with stage IB-IIIA non-small cell lung cancer.

II. To compare the adverse event rates and drug discontinuation rates due to adverse events with the addition of MK-3475 (pembrolizumab) plus standard of care (combination and/or sequential; Arms B and C) vs. standard of care alone (Arm A) as well as Arm B versus Arm C in patients with stage IB-IIIA non-small cell lung cancer.

III. To compare the DFS and OS between MK-3475 (pembrolizumab) plus standard of care (combination and/or sequential; Arms B and C) vs. standard of care alone (Arm A) by PD-L1 expression status (>= 50% vs < 50%) in patients with stage IB-IIIA non-small cell lung cancer.

IV. To compare the DFS and OS between MK-3475 (pembrolizumab) plus standard of care (combination and/or sequential; Arms B and C) vs. standard of care alone (Arm A) in patients with stage IB-IIIA non-small cell lung cancer that receive at least 2 cycles of initial adjuvant chemotherapy.

QUALITY OF LIFE OBJECTIVES:

I. To compare patient-reported quality of life (QOL) one year after randomization as assessed by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Core (C)30 between patients randomized to receive adjuvant chemotherapy followed by MK-3475 (pembrolizumab) (Arm B), and those randomized to receive adjuvant chemotherapy + observation (Arm A).

II. To compare patient reported QOL one year after randomization as assessed by EORTC QLQ-C30 between patients randomized to receive adjuvant chemotherapy + MK-3475 (pembrolizumab) concomitantly (Arm C) and those randomized to receive adjuvant chemotherapy + observation (Arm A).

III. To compare patient-reported QOL at completion of chemotherapy as assessed by the EORTC QLQ-C30 between patients randomized to receive adjuvant chemotherapy + MK-3475 (pembrolizumab) concomitantly (Arm C) and those randomized to receive adjuvant chemotherapy + observation or adjuvant chemotherapy followed by MK-3475 (pembrolizumab) (Arms A and B combined).

IV. To present longitudinal trajectories by arm of patient-reported dyspnea and coughing as assessed by the EORTC QLQ-Lung Cancer (LC13).

CORRELATIVE SCIENCE OBJECTIVES:

I. To compare the DFS and OS with the addition of MK-3475 (pembrolizumab) (combination and/or sequential) to standard of care platinum-based adjuvant therapy (Arms B and C) vs standard of care (Arm A) in the PD-L1 subgroup of patients with PD-L1 expression status (>= 1% vs < 1%).

II. To compare the DFS and OS with the addition of MK-3475 (pembrolizumab) (combination and/or sequential) to standard of care platinum-based adjuvant therapy (Arms B and C) vs. standard of care (Arm A) by tumor mutational burden status (high vs. low) in patients with stage IB-IIIA non-small cell lung cancer.

III. To identify a cell-free deoxyribonucleic acid (cfDNA) marker associated with high-risk of recurrence and improved DFS and OS with the addition of MK-3475 (pembrolizumab) to standard adjuvant chemotherapy (Arms B and C).

OUTLINE: Patients are randomized to 1 of 3 arms.

ARM A:

INITIAL THERAPY: Patients receive 1 of 4 platinum doublet regimens* based on the treating physician's choice. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

CONTINUANCE THERAPY: Patients then undergo observation.

ARM B:

INITIAL THERAPY: Patients receive 1 of 4 platinum doublet regimens* based on the treating physician's choice. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

CONTINUANCE THERAPY: Patients then receive pembrolizumab intravenously (IV) over 25-40 minutes on day 1. Treatment repeats every 21 days for 17 cycles in the absence of disease progression or unacceptable toxicity.

ARM C:

INITIAL THERAPY: Patients receive 1 of 4 platinum doublet regimens* based on the treating physician's choice and pembrolizumab IV over 25-40 minutes on day 1. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

CONTINUANCE THERAPY: Patients then receive pembrolizumab IV over 25-40 minutes on day 1. Treatment repeats every 21 days for 13 cycles in the absence of disease progression or unacceptable toxicity.

*ACCEPTABLE REGIMENS: DOUBLET I: Patients receive cisplatin IV over 1-2 hours and pemetrexed IV over 10 minutes on day 1 of each cycle.

DOUBLET II: Patients receive carboplatin IV over 30 minutes and pemetrexed IV over 10 minutes on day 1 of each cycle.

DOUBLET III: Patients receive cisplatin IV over 1-2 hours on day 1 of each cycle and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 of each cycle.

DOUBLET IV: Patients receive carboplatin IV over 30 minutes and paclitaxel IV over 3 hours on day 1 of each cycle.

After completion of study treatment, patients are followed up at 6 weeks, then every 3 months for 2 years from randomization, every 6 months for years 2-4, and then annually for up to 10 years from randomization.
