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

Impact of Melanoma Adjuvant Treatment With Tafinlar® + Mekinist® (Dabrafenib + Trametinib) on Patients Quality of Life (QoL) and Clinical Outcomes in Portuguese Real World Setting

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.

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.

Inclusion Criteria:

• Patients with complete surgical resection of histologically confirmed AJCC (8th edition) clinical stage III (IIIA, IIIB, IIIC, IIID) melanoma, in whom a decision for adjuvant treatment with dabrafenib and trametinib has been made before entering the study

  • V600E/K mutation-positive cutaneous melanoma
  • Adjuvant treatment with combination therapy of Dabrafenib (Tafinlar®) and Trametinib (Mekinist®) as indicated in the SmPC and by prescription, that has been started before inclusion of the patient into the study;
  • ≥ 18 years of age
  • Written informed consent signed.

Exclusion Criteria:

• Lack of basic demographic (gender, age, age at diagnosis) and staging data (Stage at diagnosis; Breslow index; Clark level; BRAF mutation; BRAF test date; Surgery date).
