Evaluating the Efficacy of Atezolizumab in Advanced Non-small Cell Lung Cancer (NSCLC)

NCT03014648

Description:

This is a phase II clinical trial aimed at evaluating the efficacy of PD-L1 inhibition with atezolizumab in advanced squamous and non-squamous NSCLC patients previously treated with anti-PD-1 therapy with either nivolumab or pembrolizumab. In order to account for the variability of response kinetics to PD-1 directed therapy, patients will be enrolled in 3 parallel cohorts based on the best overall response to PD-1 directed therapy. - Cohort 1 (progressive disease) - Cohort 2 (stable disease with minimum 12 weeks of therapy) - Cohort 3 (partial to complete response followed by progressive disease)

Purpose

This is a phase II clinical trial aimed at evaluating the efficacy of PD-L1 inhibition with atezolizumab in advanced squamous and non-squamous NSCLC patients previously treated with anti-PD-1 therapy with either nivolumab or pembrolizumab. In order to account for the variability of response kinetics to PD-1 directed therapy, patients will be enrolled in 3 parallel cohorts based on the best overall response to PD-1 directed therapy. - Cohort 1 (progressive disease) - Cohort 2 (stable disease with minimum 12 weeks of therapy) - Cohort 3 (partial to complete response followed by progressive disease)

Detailed Description

      Atezolizumab will be given on day 1 of a 21-day cycle at 1200 mg IV. Radiographic assessments
      for disease response will occur every 6 weeks while on treatment. Confirmatory scans should
      be obtained ≥ 4 weeks following initial documentation of objective response or progressive
      disease on atezolizumab therapy.

      Atezolizumab will be given as long as the patient continues to experience clinical benefit in
      the opinion of the investigator or until unacceptable toxicity, symptomatic deterioration
      attributed to disease progression.

      Patients will be followed for 12 months or until death as per standard of care after
      discontinuation of Atezolizumab or until death, whichever occurs first.

AtezolizumabExperimentalAtezolizumab will be given on day 1 of a 21-day cycle at 1200 mg IV over 60 (plus or minus 15) minutes for first infusion; can be decreased to 30 (plus or minus 10) minutes for subsequent cycles. Atezolizumab will be given as long as the patient continues to experience clinical benefit in the opinion of the investigator or until unacceptable toxicity, symptomatic deterioration attributed to disease progression. There will be no dose reduction for Atezolizumab. Patients may temporarily suspend study treatment for up to 84 days beyond the scheduled date of delayed infusion if study drug-related toxicity requiring dose suspension is experienced. If Atezolizumab is held because of adverse events for greater than 84 days beyond the scheduled date of infusion, the patient will be discontinued from Atezolizumab and will be followed for safety and efficacy.

Primary Outcome Measures

Measure:Best Overall Response (BOR)
Time Frame:Up to 6 years
Safety Issue:
Description:Best response recorded is recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Per RECIST v1.1: Complete Response (CR) - Disappearance of all target lesions. Any pathological lymph nodes (target or non-target) with reduction in short axis to <10 mm. Partial Response (PR): ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Secondary Outcome Measures

Measure:Duration of Response (DOR)
Time Frame:Up to 6 years
Safety Issue:
Description:The length of time that a tumor continues to respond to treatment from first documentation of response until disease progression.Per RECISIt v1.1: Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (target or non-target) with reduction in short axis to <10 mm. Partial Response (PR): ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Progressive Disease (PD):≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression.
Measure:Progression-free survival (PFS)
Time Frame:Up to 6 years
Safety Issue:
Description:The length of time during and after treatment that a patient lives with disease but without disease progression. Per RECISIT v1.1: Progressive Disease (PD):≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression.
Measure:Overall survival (OS)
Time Frame:Up to 6 years
Safety Issue:
Description:The length of time from start of treatment that patients are still alive.
Measure:Adverse Events ≥ Grade 3
Time Frame:Up to 6 years
Safety Issue:
Description:Adverse events will be graded using the Cancer Therapy Evaluation Program (CTEP) Common Terminology Criteria for Adverse Events (CTCAE) version 4. Adverse events of grade 3 or greater determined to be possibly, probably or definitely related to treatment, or that result in dose holds or reductions, will be collected and reported. Adverse events and serious adverse events will be tabulated in order of prevalence, with the highest grade reported by each patient. The number and percent of subjects reporting adverse events will be summarized by category
