E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the study is to assess if an early switch (i.e. switch at 3 months) from targeting the Ras/Raf signalling pathway by BRAF and MEK inhibition to immunologic checkpoint inhibition with an anti-PD-L1 antibody leads to prolongation of progressionfree and overall survival outcomes in patients with unresectable or metastatic BRAFV600 mutant melanoma. Furthermore, the safety of the study treatment will be assessed. The following endpoints will help to address the study objectives: Primary endpoint: PFS1 defined as time from start of run-in phase (date of first intake of study drug) to first documented tumor progression date according to RECIST v. 1.1 (PD1) or death by any cause, whichever occurs first (Figure 2). PFS1 will be based on the disease assessment or date of death provided by the local investigator. For patients who remain alive and whose disease has not progressed, PFS1 will be censored on the date of last visit/contact when a disease assessment was performed. |
|
E.2.2 | Secondary objectives of the trial |
Secondary endpoints: • Time to Second Objective Disease Progression (PFS2) • Safety • Overall Survival (OS) of patients defined as the time from start of run-in phase until documented date of death, for any cause. Patients still alive will be censored at the time of last visit/contact. • Overall survival rate at 12 months, 24 months, 36 months, and 48 months defined as the rate of patients alive 12 months, 24 months, 36 months, and 48 months, respectively after start of run-in phase • 12-months and 24-months disease control rate (DCR), best overall objective response rate (OORR), time to overall objective response (OOR) and duration of OOR. • Rate of patients with progressive disease who could not cross-over to subsequent line of therapy due to deterioration of ECOG status or multiple and/or symptomatic brain metastasis and/or leptomeningeal disease o From vemurafenib + cobimetinib to atezolizumab (Arm A) o From atezolizumab to vemurafenib + cobimetinib (Arm B) • PFS3 |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
The translational research program will focus on the discovery of biomarkers for improvement of melanoma therapy, and to evaluate the biologic effects of treatment sequence on the molecular profile and biomarker expression in tissue and plasma. Therefore tumor tissue and blood samples, respectively will be analyzed to assess the relationship of the tumor immune and signaling biomarker landscape and efficacy, to evaluate non-inherited genetic alterations of circulating free tumor-specific DNA in plasma and to assess and monitor the immunophenotype in peripheral blood mononuclear cells.
The patient questionnaires will focus on the medication adherence of the patients. Paper-based as well as electronic documentation will be available. The patients can choose between both. Since the use of electronic systems for self-reported medication adherence is a new approach in melanoma research, the aim of this approach is to analyze both the patient group that opts for Alcedis eMARS as well as the patient group that opts for the paper-based documentation. Reasons for not participating in the Alcedis eMARS program will be documented. Furthermore the user-friendliness, practicality, and user satisfaction of Alcedis eMARS will be assessed by patient and investigator questionnaires. In addition the quality of life of the patients will be assessed. To address these objectives, standardized and study-specific patient questionnaires will be used. To analyze the investigator´s satisfaction with Alcedis eMARS, the investigator has to fill in specific questionnaires on different timepoints. Additionally, the self-reported medication adherence will be analyzed in both patient groups (patients using Alcedis eMARS or using the paper-based documentation) also taking the results of the pill-count done by the study centers into account. |
