NCT ID: NCT03014648

Last Updated: 2023-12-13

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 28 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-07-18
• Study Completion Date: 2022-03-31

Brief Summary

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.

Study Groups

Atezolizumab

Atezolizumab 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.

Group Type: EXPERIMENTAL

Atezolizumab

Intervention Type: DRUG
