简要总结
Mycobacterium abscessus (MABS) is a group of rapid-growing, multi-drug resistant non-tuberculous mycobacteria (NTM) causing infections in humans. MABS pulmonary disease (MABS-PD) can result in significant morbidity, increased healthcare utilisation, accelerated lung function decline, impaired quality of life, more challenging lung transplantation, and increased mortality. While the overall numbers affected is small, the prevalence of infections is increasing worldwide. The Finding the Optimal Regimen for Mycobacterium abscessus Treatment (FORMaT) trial aims to produce high quality evidence for the best treatment regimens to maximise health outcomes and minimise toxicity and treatment burden, as well as developing biomarkers (serology, gene expression signatures, and radiology) to guide decisions for starting treatment and measuring disease severity in patients with MABS PD.
详细描述
Mycobacterium abscessus (MABS) are a group of non-tuberculous mycobacteria (NTM) found in water and soil habitats that exhibit high levels of intrinsic multi-drug resistance. They are recognised opportunistic human pathogens capable of causing chronic pulmonary disease (MABS-PD), predominantly in individuals with underlying inflammatory lung diseases.
Finding the Optimal Regimen for Mycobacterium abscessus Treatment (FORMaT) is an iterative, standing, platform trial with innovative and adaptive properties that evaluate and develop the optimal combinations of therapies for children and adults with MABS-PD to clear MABS infection with acceptable tolerance. We will use these opportunities afforded by the clinical trial platform to establish discovery studies to: (i) understand the effects of disease and treatment on health-related quality of life, (ii) determine cost effectiveness of interventions, (iii) optimise pharmacokinetic drug dosing, (iv) understand susceptibility to MABs-PD, (v) develop biomarkers of clinical disease, (vi) investigate genomics of MABs strains causing MABs-PD and development of antimicrobial resistance.
FORMaT provides a pragmatic design to address challenges to develop an evidence base for the first time for MABS-PD. Initially, the trial has been designed to test therapies that are currently the basis for treatment guidelines for MABS-PD. The trial has the capacity to add new treatments and to eliminate therapies because of futility as they either lack efficacy or cause unacceptable toxicity. Novel therapeutic approaches are then tested against the previously determined optimal approaches, thus leading in an iterative fashion to improve microbiological clearance, and health outcomes associated with MABS-PD. The trial is designed as a series of trials within the main trial to enable investigation of the different phases of treatment; intensive (intravenous treatment phase) and consolidation (oral and or inhaled treatment phase) based on clinical guidelines. The primary outcome for each trial is microbiological clearance with clinical tolerance (Grade 1 or 2) based on Common Terminology Criteria for Adverse Events (version 5). This enables subjects to continue in the trial even if tolerance is poor or they change treatments in a specific phase of the trial as those events contribute to the primary outcome determination.

盲法说明
The FORMAT trial may include placebo controlled double blind randomised interventions in the future, but the initial intervention program is randomised but open label.
There will be three stages of randomisation in the intervention program of this study, dictating the treatment the participant will receive. Randomisation at each level will be conducted using the method of minimisation. Each randomisation level will be planned to enable flexibility via pre-planned adaptations.

结局指标
主要结局
The primary outcome of the Intervention Program is microbiological clearance of MABS with good tolerance of the interventions.
时间窗: Screening (Day 0) to End of treatment plus four weeks off-treatment (Final Outcome Visit (Week 56 for those allocated to Immediate Consolidation or Week 62 for those allocated to Prolonged Intensive).
The primary outcome of the Intervention Program is microbiological clearance of MABS with good tolerance of the interventions. Definition of MABS clearance at final outcome: Negative MABS cultures from four consecutive sputum samples with one of those sputum specimens collected four weeks after the completion of consolidation therapy, or a MABS negative Bronchoalveolar Lavage (BAL) collected four weeks after completion of consolidation. Definition of tolerance: Tolerance is based on the Common Terminology Criteria for Adverse Events (CTCAE version 5.0). Only adverse events that are attributed as either "possibly-", "probably-", or "definitely-" related to study drug will be assessed in the determination of tolerance. "Good" tolerance is defined as no adverse events occurring or only adverse events coded as CTCAE grades 1 and 2. "Poor" tolerance is defined as any adverse events attributed as possibly-, probably-, or definitely-related to study drug coded as CTCAE grades 3, 4, or 5.
Nested Study A1.1 Type of Short Intensive Therapy - MABS clearance from respiratory sample(s) with tolerance.
时间窗: Screening (Day 0) to the End of Short Intensive Therapy (Week 6).
To compare the microbiological clearance of MABS from respiratory samples collected at 4 weeks with good tolerability assessed at the end of short intensive therapy between the use of Inhaled Amikacin (Arm B) and the use of Intravenous Amikacin (Arm A) given during intensive phase. Definition of MABS clearance is 3 MABS negative sputum samples or ONE MABS negative Bronchoalveolar Lavage (BAL) at end of Short Intensive Therapy. "Good" tolerance is defined as no adverse events occurring or only adverse events that are attributed as either "possibly-", "probably-", or "definitely-" related to study drug coded as CTCAE grades 1 and 2.
Nested Study A1.2 - Duration of intensive therapy for patients completing short intensive treatment with ongoing positive MABS cultures collected at 4 weeks and randomised to either a further 6 weeks intensive therapy or immediate consolidation.
时间窗: Screening (Day 0) to EITHER the End of Prolonged Intensive Therapy (for those allocated to Prolonged Intensive) OR Week 12 Visit (for those allocated to immediate consolidation therapy).
To compare the microbiological clearance from samples collected at 10 weeks with good tolerability between those who are allocated to prolonged intensive therapy and those allocated to immediate consolidation following short intensive therapy. MABS clearance, assessed at the end of prolonged intensive therapy (for those allocated to prolonged intensive) or at 12 weeks (for those allocated to immediate consolidation) will be defined as negative MABS cultures from all 3 sputum samples or from one BAL sample collected at 10 weeks. "Good" tolerance is defined as no adverse events occurring or only adverse events that are attributed as either "possibly-", "probably-", or "definitely-" related to study drug coded as CTCAE grades 1 and 2.
Nested Study 1.3 Consolidation Therapy - The use of oral therapy only or oral therapy and inhaled amikacin for consolidation therapy.
时间窗: Start of Consolidation Therapy (Date of Randomisation to Consolidation Therapy) to End of Treatment plus 4 weeks off treatment (Final Outcome Visit - Week 56 for those randomised to Immediate Consolidation or Week 62 for those in Prolonged Intensive).
To compare the microbiological clearance with good tolerability of MABS between those allocated to consolidation therapy with oral treatment and those allocated to consolidation therapy with oral treatment and additional Inhaled Amikacin at Final Outcome. Definition of MABS clearance at final outcome: Negative MABS cultures from four consecutive sputum samples with one of those sputum specimens collected four weeks after the completion of consolidation therapy, or a MABS negative Bronchoalveolar Lavage (BAL) collected four weeks after completion of consolidation. "Good" tolerance is defined as no adverse events occurring or only adverse events that are attributed as either "possibly-", "probably-", or "definitely-" related to study drug coded as CTCAE grades 1 and 2.
