A Study to Investigate Atezolizumab Subcutaneous in Patients With Previously Treated Locally Advanced or Metastatic Non-Small Cell Lung Cancer

Phase 3
Completed
Conditions
Non-Small Cell Lung Cancer
Interventions
Registration Number
NCT03735121
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This study will evaluate the pharmacokinetics, safety, and efficacy of atezolizumab subcutaneous (SC) compared with atezolizumab intravenous (IV) in participants with locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) who have not been exposed to cancer immunotherapy (CIT) and for whom prior platinum-based therapy has failed. The study is comprised of two parts, as follows: A dose-finding part (Part 1, Phase Ib) will aim to identify the dose of atezolizumab SC to be tested in Part 2. A dose-confirmation part (Part 2, Phase III, randomized) will aim to confirm that the dose moved forward from Part 1 yields drug exposure that is comparable to that of atezolizumab IV.

Part 2: Progression-Free Survival (PFS)From study start to the first occurrence of disease progression or death from any cause, whichever occurs first (Up to approximately 72 months).

PFS is defined as the time from study start to the first occurrence of disease progression as determined by the investigator according to RECIST v1.1 or or death from any cause (whichever occurs first).

Part 2: Overall Survival (OS)From study start to death from any cause (Up to approximately 72 months)

OS defined as the time from study entry to death from any cause.

Part 2: Duration of Response (DOR)From first occurrence of documented objective response to disease progression or death from any cause, whichever occurs first (up to approximately 72 months)

DOR is defined as the time from first occurrence of a documented objective response to disease progression as determined by the investigator according to RECIST v1.1. or death from any cause, whichever occurs first. Objective response is defined as the percentage of participants having a CR or PR as determined by investigator assessment of radiographic disease per RECIST v1.1. CR is the disappearance of all target lesions and any pathological lymph nodes must have reduction in short axis to \< 10 mm. PR is defined as at least a 30% decrease in the SOD of target lesions, taking as reference the Baseline sum diameters in the absence of CR.

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the National Cancer Institute Common Terminology Criteria for AEs, version 5.0 (NCI-CTCAE, v5.0).

Part 2: Convenience, Ease of Administration, and Overall Satisfaction With Atezolizumab SC Assessed Using HCP Subcutaneous Perspective QuestionnaireAfter HCP has completed administering at least 3 doses of atezolizumab SC across all participants in Part 2 (Up to approximately 72 months)

The HCP Subcutaneous Perspective Questionnaire consists of five items evaluating the convenience, ease of administration and overall satisfaction with atezolizumab SC, as well as reasons for HCP-reported satisfaction or dissatisfaction.

Part 2: Model Predicted AUC at Steady State (AUCss) of AtezolizumabAtezo SC: Pre&postdose C1D1, postdose C1 Days 2,4,8, Pre&postdose C2,D1 and Predose on D1 of C3,4,8,12 and 16 ; Atezo IV: Pre&postdose on C1D1, postdose C1 Days 2,4,8; Pre&postdose C2D1, Predose on D1 of C3,4,8,12, and 16 (up to approximately 16 months)

Part 2: Functioning and Global Health Status Over Time, as Assessed by European Organization for Research and Treatment of Cancer (EORTC) Item Library (IL)57From Day 1 of Cycles 1-6 and then every other cycle up to treatment discontinuation visit (Up to approximately 72 months)

EORTC IL57 questionnaire has10 items and covers 3 scales: physical functioning (PF), role functioning (RF) \& global health status/quality of life (GHS/QoL) \& 1 item from EORTC Item Library. PF scale has 5 items evaluating the extent to which participants have trouble doing strenuous activities; taking long walks \& short walks; need to stay in bed or a chair; need help with eating, dressing, bathing/using toilet. RF scale has 2 items evaluating extent to which participants are limited in doing work \& pursuing leisure activities in previous week. GHS/QoL scale has 2 items evaluating participants' overall health \& QoL in previous week. Questions are answered on a 4-point Likert scale (where 1="Not at all" to 4="Very much") for physical and role functioning \& a 7-point scale (where 1="Very poor" to 7="Excellent") for GHS/QoL. For each scale, mean of the items are linearly transformed to obtain scores from 0-100, where 100 =best possible score. Higher score = better outcome.

Part 2: Overall Satisfaction With Treatment Over Time, Assessed by the Modified Satisfaction With Therapy (SWT) Scale of the Cancer Therapy Satisfaction Questionnaire (CTSQ)Day 1 Cycle 3 or at treatment discontinuation visit (Up to approximately 72 months)

Modified SWT scale of the CTSQ consist of seven items that measures seven domains related to satisfaction with cancer therapy. These include worthwhile, difficulty, benefits, feelings about side effects, form of therapy, overall satisfaction, and if participants would choose the therapy taking everything into consideration. Each domain is rated on a 5-point scale, with 1 representing the worst response and 5 representing the best response, except in the case of one reverse-scored item. mean of the items are linearly transformed to obtain scores from 0-100, where 100 =best possible score Higher scores are associated with higher satisfaction.

Part 2: Percentage of Participants With ADAs to rHuPH20 After SC Administration Relative to the Prevalence of ADAs at BaselineFrom first dose of atezolizumab up to treatment discontinuation visit (Up to approximately 72 Months)
Part 2: Convenience, Potential Time Savings, and Overall Satisfaction With Atezolizumab SC Compared With Atezolizumab IV as Assessed by the Health Care Professional (HCP) SC Versus IV Perspective QuestionnaireAfter HCP has completed administering at least 3 doses of atezolizumab SC and IV across all participants in Part 2 (Up to approximately 72 months)

The HCP Subcutaneous Versus IV Perspective Questionnaire consists of five items evaluating the number of atezolizumab SC and IV administrations done, convenience, potential time savings, and overall satisfaction with atezolizumab SC and atezolizumab IV, as well as reasons for HCP-reported satisfaction or dissatisfaction.

Part 2: Objective Response Rate (ORR)From treatment initiation until disease progression or loss of clinical benefit (Up to approximately 72 months).

ORR is defined as the percentage of participants having a complete response (CR) or partial response (PR) as determined by investigator assessment of radiographic disease per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. CR is the disappearance of all target lesions and any pathological lymph nodes must have reduction in short axis to \< 10 millimeters (mm). PR is defined as at least a 30% decrease in the sum of diameters (SOD) of target lesions, taking as reference the Baseline sum diameters in the absence of CR.

Part 2: Overall Patient-reported AE's Burden Over Time, Assessed by the Treatment-related Symptom Burden Item From the EORTC IL57Day 1 of Cycles 1-6 and then every other cycle up to treatment discontinuation visit (Up to approximately 72 months)

The overall patient-reported AE burden was assessed using the a single item from the EORTC IL57 questionnaire i.e To what extent have you been troubled with side-effects from your treatment?. The questions is answered on a 4-point Likert scale where 1="Not at all" to 4="Very much". Higher scores indicates greater AE burden.
