Molecular heterogeneity in cancer tumours make it a complex disease to manage and treat. However, there have been significant advancements made in the detection of molecular alterations and we are able to now define distinct disease subtypes which permit targeted selection of therapies, thus optimizing treatment responses for patients and improving their survival.
With CARMA-BROS we will address the objectives that follow.
Primary Objectives:
- To create a cohort of patients through which to better understand the natural history of disease in Canadian cancer patients with tumours that have been molecularly subtyped and identified to have rare molecular alterations.
-
To compare the natural history, stage distribution, treatment outcomes such as treatment effectiveness (composite of disease progression or death) and treatment toxicities across different patients with different molecular alterations, receiving different lines and types of therapy.
Secondary Objectives:
- To determine the incidence, time to development, prevalence, and outcomes of patients with specific patterns of spread, such as brain metastases compared to those without, by different therapies and by molecular alterations.
- To better understand real-world treatment patterns of rare molecular alterations in the Canadian context, across geographic or other factors, and how treatment patterns evolve over time and as new therapies become available, how patients are investigated and how targeted and other biomarkers are used as part of clinical practice in these patients.
- To assess quality of life in patients with rare molecular alterations across different stages, lines and types of therapy.
- To perform exploratory health economic evaluations focused on the costs and benefits of managing patients with rare molecular alterations.
- To perform biomarker analyses, where appropriate, to improve our understanding of these rare molecular alterations.

Group/Cohort | Intervention/treatment |
---|---|
Prospective
Living cancer patients with histologically confirmed rare molecular alterations in their tumours, such as in ALK, EGFR, ROS1, BRAF, and KRAS G12C from participating sites/cancer centres across Canada.
|
Drug: Cancer treatment with tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapeutic agents.
Observing cancer patients who have received or are currently receiving tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapies for their cancer treatment. Other: Patient-reported outcomes (PROs) Prospectively enrolled participants will be provided with survey packets comprised of different PRO instruments at the initial/baseline visit, at 3 month follow up intervals and at the time when treatment/therapy is changed. |
Retrospective
Deceased cancer patients who had histologically confirmed rare molecular alterations in their tumours, such as in ALK, EGFR, ROS1, BRAF, and KRAS G12C from participating sites/cancer centres across Canada.
|
Drug: Cancer treatment with tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapeutic agents.
Observing cancer patients who have received or are currently receiving tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapies for their cancer treatment. |
Comparator group
All cancer patients without rare molecular alterations in their tumours. This group will be established in order to determine baseline characteristics and outcomes, including treatment outcomes, of more standard treatments such as systemic chemotherapy or immunotherapy.
|
- Composite of Progression Free Survival [PFS] or Overall Survival [OS] [ Time Frame: From the start date of cancer therapy until the date of first documented progression or date of death (any cause), assessed up to 120 months ]Composite of disease progression or death
- Brain metastasis/other metastatic tumours [ Time Frame: From the start date of cancer therapy until the date of first documented brain/other metastasis, assessed up to 120 months ]Confirmed through imaging (MRI, CT) or determined through treatment indication(s), for example, brain radiation therapy (surrogate for presence of brain metastasis)
- EORTC quality of life questionnaires (QLQ) - cancer patient-reported health related quality of life [ Time Frame: Baseline and serial changes every 3 months, including whenever there is a change in treatment, up to 120 months (the duration of this study) ]Prospectively enrolled participants will complete the following health related quality of life surveys: EORTC QLQ-C30 (core) and EORTC QLQ-LC13 (disease specific module)
- EQ-5D-5L - patient-reported health related quality of life measure [ Time Frame: Baseline and serial changes every 3 months, including whenever there is a change in treatment, up to 120 months (the duration of this study) ]Prospectively enrolled participants will complete the health related quality of life survey: EQ-5D-5L.
- Patient-reported economic impact [ Time Frame: Baseline and serial changes every 3 months, including whenever there is a change in treatment, up to 120 months (the duration of this study) ]Prospectively enrolled participants will complete the "Work Productivity and Activity Impairment Questionnaire: General Health" (WPAI:GH) and other economic impact questions that capture indirect costs incurred as a result of their disease.
