Finding the Optimal Regimen for Mycobacterium Abscessus Treatment (FORMaT)
Finding the Optimal Regimen for Mycobacterium Abscessus Treatment (FORMaT)
Study Overview
Status
Detailed Description
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.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Appendix A1 - MABS clearance from respiratory samples with tolerance at final outcome
Time Frame: 56 weeks for participants who received short intensive therapy and 62 weeks for participants who received prolonged intensive therapy.
|
The probability of MABS clearance with good tolerance at final outcome. MABS clearance defined as: Negative MABS cultures from 4 consecutive sputum samples with one of those sputum specimens collected four weeks after the completion of consolidation therapy or a MABS negative BAL collected four weeks after completion of consolidation. Tolerance will be defined using 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 defined as no adverse events occurring or only adverse events coded as CTCAE grades 1 and 2. "Poor" as any adverse events coded as CTCAE grades 3, 4, or 5. |
