QoL is often not assessed in real-world studies; hence, there is limited understanding about the real-world QoL of patients diagnosed with CLL. Besides, studies evaluating QoL have largely focused on comparing treated and untreated populations. In particular, QoL of patients treated with acalabrutinib has not been evaluated in a real-life setting. The aim of this study is to describe the QoL of CLL patients treated with acalabrutinib between the treatment initiation and twelve months after, in a real-life setting.
PROTOCOL SYNOPSIS Background/Rationale: CLL is the most prevalent leukemia among adults. The estimated incidence of CLL was 4 674 in 2018 in France, 59% in men with a median age of 71 in men and 73 in women. 95% of patients are older than 51 yrs at diagnosis. 5-yr survival is above 89% for patients diagnosed between 2010 and 2015. Yet, CLL cannot be cured. Some patients will require monitoring while others need to be treated. Treatment is based on both chemo-immunotherapies (CIT) and target therapies. Treatment choice depends on several parameters: age, patient general condition, comorbidities, prognostic factors, cytogenetic status. CIT have shown to improve overall survival (OS). Targeted therapies have changed the management and offer treatment options among older patients and those with comorbidities who have unacceptable side effects with CIT. Acalabrutinib (also known as ACP-196 and Calquence®), is a selective and irreversible small molecule inhibitor of BTK. Authorized as 1st or 2nd line treatment in France in November 2020. Its safety and efficacy were explored in phase III clinical trials ELEVATE-TN, ASCEND, and ELEVATE-R/R. Because CLL is, by definition, a chronic disease and requires long-term treatment and because many patients have comorbidities, it is essential to consider quality of life (QoL) of patients.14 In addition, the condition itself substantially impacts QoL.Patients with CLL experienced worse QoL than the general population across several domains, including symptoms (e.g. fatigue and sleep disturbances), as well as physical and mental functioning. Acalabrutinib has shown great efficacy associated with a good safety profile in clinical trials11,12,14. Moreover, it is an oral treatment that does not require intravenous injections when taken as monotherapy. This treatment modality associated with the favorable safety profile of acalabrutinib could have a positive impact on the QoL of patients. Indeed, patients could continue to live a normal life at home, surrounded by their relatives. QoL is often not assessed in real-world (RW) studies; hence, there is limited understanding about the RW QoL of patients diagnosed with CLL. Besides, studies evaluating QoL have largely focused on comparing treated and untreated populations. In particular, QoL of patients treated with acalabrutinib has not been evaluated in a real-life setting. The aim of this study is to describe the QoL of CLL patients treated with acalabrutinib between the treatment initiation and 12 months after, in a real-life setting. Objectives: Primary Objective : To measure QoL score of CLL patients treated with acalabrutinib, from treatment initiation and up to 12 months -Overall scores and scores in each domain of QoL questionnaires (EORTC-QLQ-C30 ) at acalabrutinib treatment initiation and at 3, 6, 9 and 12 months after initiation -Proportion of patients with an increase, a decrease, or no change in QoL scores over time (between each time point) Main Secondary Objectives: To describe QoL and precisely the level and evolution of all symptoms -Patients demographics (age, gender…) at acalabrutinib treatment initiation -Clinical characteristics at acalabrutinib treatment initiation (CLL diagnosis, Binet classification, comorbidities of interest) -Clinical characteristics quarterly up to 12 months (disease status) -Score is calculated with standardized EORTC-CLL17 questionnaire At acalabrutinib treatment initiation and at 3, 6, 9 and 12 months after initiation To measure the evolution of observance -Score is calculated with standardized GIRERD grid at 3, 6, 9 and 12 months after initiation To describe treatment patterns in CLL patients treated with acalabrutinib, overall and by age group -Acalabrutinib treatment: line, monotherapy or with obinutuzumab, posology, duration, reason for discontinuation if any To describe participating sites characteristics -Type of physician practice (public/private/mixed) -Type of care structure (CHU/ CHG…) -Existing patient support program (yes/no, type) Methods: Study design: This is a retrospective, observational study focusing on the QoL and experience of CLL patients treated with acalabrutinib in France in a real-life setting. This study is using secondary data of patients included in the national multicenter longitudinal cohort PLATON (sponsor HOSPITALIDEE) (clinical trial registration N° 2023-A01569-36). This cohort is enrolling patients with hematological malignancies including CLL patients. A follow-up of 12 months from initial cancer diagnosis / or patient enrollment is planned in the PLATON study. The current AQUALIS study mainly aims at describing CLL patient QoL and experience from acalabrutinib initiation, quarterly and up to 12 months post initiation. Patient and disease characteristics, treatment patterns, disease status over time will also be described. Thus, the patient population eligible for entering the AQUALIS study will be treatment naïve CLL patients enrolled in the PLATON study and having initiated acalabrutinib, at the time of data extraction. Only patients with a full T0 will be considered as included. Several data extraction from PLATON database and data cut-off are planned to address AQUALIS study objectives and planned publication plan. No extra-visit, nor specific additional examination nor intervention are required for patients eligible to enter the AQUALIS study. Data to be extracted and analyzed will be exclusively those already recorded in the PLATON database. HOSPITALIDEE will insure that in each center participating to PLATON cohort, all patients fulfilling the PLATON eligibility criteria have been informed about the PLATON study before being enrolled in the PLATON database and do not object to secondary use of their data. The AQUALIS study does not involve human person according to the French legislation. Data Source(s): The AQUALIS study will be a secondary use of data issued from the French PLATON cohort. The PLATON cohort is a national prospective cohort enrolling patients diagnosed with malignant hemopathies, aiming at to offer personalized information to patients to improve their QoL and guide their use of complementary care. PLATON is designed to ensure patients follow-up in the long term and on a European scale. This project is sponsored by HOSPITALIDEE and coordinated by Loic Raynal under the scientific responsibility of Pr Loïc Ysebaert. The sponsor has been granted with appropriate regulatory and ethics local approvals for the conduct of the study. Patients eligible to PLATON are informed about the study and are requested to sign a specific informed consent if they do agree for participation and for their data being processed. It is planned that 120 patients are enrolled and followed-up to 12 months from enrollment. Data are collected at patient inclusion, and on a regular basis (every 3 months) during the follow-up, according to routine practice. Socio-demographic, clinical, biological data, treatments patterns, etc..(Pathology, treatments, history, lifestyle, sociodemographic analysis, patient profile, preferences…) are collected via an electronic data capture tool and hosted in a centralized securized data center. Patient QoL and experience is also collected at 5 timepoints using 4 questionnaires . The PLATON database is managed by HOSPITALIDEE using their own software. A data-management plan and a consistency check program were established during database development. Quality controls of the data are performed: i) automatic data consistency check; ii) data management control through regular sending of queries; iii) regular e-control of entered data by the project manager; iv) remote and / or on-site data monitoring of at least 100% of the data entered. Data collection and hosting, data management, and statistical analysis of PLATON data are handled by HOSPITALIDEE. No patient-level data will be transmitted to AstraZeneca. Only aggregated data will be delivered, based on the current AQUALIS protocol and a related statistical analysis plan. Study population The AQUALIS study population will be a subgroup of patients enrolled in PLATON database following inclusion and exclusion criteria as described below. Inclusion criteria: The following patients will be eligible for inclusion in the AQUALIS study: - Patient enrolled in the PLATON database - Patient ≥18 years old - Treatment naïve CLL patient treated with acalabrutinib in a real life setting. Treatment pattern is Acala mono or Acala + Obinutuzumab - Patient who do not object to his health data collected in PLATON study being re-use for analysis/research purpose - Patients who started Acala but discontinued before 12 months are also included Exclusion criteria: - Pregnant women - Patients under protection of justice - Patients over the age of 18 and unable to express their non-opposition - Patients with prior CLL treatments Exposure : Not applicable. Outcome(s): The following data will be extracted from PLATON database to address the AQUALIS study objectives. -Data extracted at Acalabrutinib treatment initiation (T0) • Eligibilty criteria • Demographics (age, sex) • Clinical characteristics at initiation (date of CLL diagnosis, Binet stage, comorbidities) • Treatment patterns: acalabrutinib treatment: (1st line, monotherapy or association with obinutuzumab, posology, start date, stop date + reason) • Existing patient support program at site • EORTC-QLQ-C30 + EORTC-CLL17 Data extracted at Acalabrutinib treatment initiation T0+ T3 (3months), +T6 (6 months), +T9 (9 months) and +T12 (12 months) • Clinical characteristics over time (disease status) • Treatment patterns: acalabrutinib treatment: (1st line, monotherapy or association with obinutuzumab, posology, start date, stop date + reason) • EORTC-QLQ-C30 + EORTC-CLL17+ Satisfaction questionnary+ GIRERD Sample Size Estimations: - Given the observational nature of the study and the descriptive nature of the primary objective, no pre-defined hypothesis testing is expected to be used to address the primary objective. - Assuming a 20% loss of follow-up, the number of patients to address the exploratory objective will be 120*0.8=96. Statistical Analysis: With a sample size of 120 patients (treated with acalabrutinib as a first-line therapy), we will have enough power to detect a change (including an improvement) in the QoL of patients over time with one QoL (EORTC-QLQ-C30). A comprehensive statistical analysis plan (SAP) will be developed before the first analysis and finalized before the database lock. A descriptive analysis will be conducted on all variables for which data have been extracted for the overall study population and sub-groups of interest. Continuous, quantitative, variable summaries will include: the number of patients (N) (with non-missing values), mean, standard deviation (SD), median, minimum, maximum, 1st, and 3rd quartiles. Categorical, qualitative, variables summaries will include the frequency and percentage of patients per category. The denominator for percentage calculations will be based on the number of observed data, unless otherwise specified. All applicable statistical tests will be two-sided and will be performed at a 5% significance level. Missing values will not be imputed. Results will be presented overall and by treatment line and by age group, as specified in the study objectives. Additional subgroups of interest may be further investigated and discussed in the protocol and/or the SAP.
