Observational Study for Melanoma Adjuvant Treatment With Tafinlar® + Mekinist® (Dabrafenib + Trametinib)

Completed
Conditions
Malignant Melanoma
Interventions
Registration Number
NCT04547946
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

The primary objective for this non-interventional study was to assess the quality of life of melanoma patients under adjuvant treatment with dabrafenib and trametinib in real world setting in Portugal through disease specific FACT-M questionnaire and generic EQ-5D-3L questionnaire. The secondary study objectives were to assess the usage of adjuvant dabrafenib and trametinib in clinical practice and to evaluate clinical outcomes in patients that started adjuvant treatment with dabrafenib and trametinib. In addition, this study aimed to explore if treatment discontinuation affects clinical outcomes in real-world practice.

Detailed Description

The prospective registration of completely resected high-risk stage III melanoma patients treated with dabrafenib and trametinib in the adjuvant setting was planned to be based on collaboration with 8 centers of excellence on melanoma patients treatment, according to their expertise and experience.

Patients were recruited from participating centers in the routine setting. This was done only if the decision about starting treatment with dabrafenib and trametinib had already been made. All patients that complied with the inclusion criteria and that started treatment with dabrafenib+ trametinib during the recruitment period were considered to participate in the study, at investigator discretion.

Health related quality of life had to be assessed by FACT-M and EQ-5D-3L questionnaires after treatment initiation in a quarterly base, according to clinical practice, including the first visit after treatment completion.

Primary Outcome Measures
NameTimeMethod
Change from baseline in EQ-5D-3L scoreBaseline, months 3-4, months 6-8, months 9-12, months 12, months 15-16

Health-related quality of life in melanoma patients defined as the mean difference in EQ-5D-3L score.

EQ-5D-3L is a descriptive questionnaire comprising five dimensions regarding mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has three response levels of severity: no problems, some problems, extreme problems. The respondent was asked to indicate his/her health state by checking the box next to the most appropriate response level of each of the five dimensions.

Change from baseline in FACT-M scoreBaseline, months 3-4, months 6-8, months 9-12, months 12, months 15-16

Health-related quality of life in melanoma patients defined as the mean difference in FACT-M (Functional Assessment of Cancer Therapy - Melanoma ) score.

FACT-M is a specific version of FACT questionnaire validated for patients with any stage of melanoma and includes items related to physical, functional, social and emotional well-being, and specific concerns of melanoma patients and melanoma patients undergoing surgery. The FACT-M Total Score (FACT-M TS) ranges from 0 to 172. Higher scores represent a better quality of life.
