Key Safety Profile Insights From COMBI-v and COMBI-d Trials in Metastatic Melanoma
TAFINLAR (dabrafenib) + MEKINIST (trametinib) combination has a well-established safety profile.
No new safety signals were seen at five years in the pooled analysis of COMBI-v and COMBI-d.1
The most common adverse events observed with TAFINLAR + MEKINIST in the pooled five-year analysis included: pyrexia, nausea, diarrhoea, fatigue, headache, chills, and vomiting.1
TAFINLAR + MEKINIST has a well-established adverse event profile, and no new safety signals were seen at five years1–3
- In the pooled analysis, adverse events led to permanent discontinuation of TAFINLAR + MEKINIST in <20% of patients.1
- No treatment-related deaths were reported in the five-year pooled analysis.1
All-causality adverse events occurring in ≥20% of patients treated with TAFINLAR + MEKINIST(five-year pooled analysis)1
Incidence of adverse events decreased over a three year period in patients who received TAFINLAR + MEKINIST4
- In a separate pooled analysis of the three-year data from the COMBI-v and COMBI-d trials, the incidence of adverse events decreased over time in patients completing at least 36 months of treatment (n=50).4
- The incidence of pyrexia more than halved from 60% at 0–6 months to 12% at 30–36 months of treatment.4
Incidence of adverse events (≥15%) over time in patients treated with TAFINLAR + MEKINIST for ≥36 months (pooled analysis at three years)4
Analysis of Pyrexia in Patients Treated with TAFINLAR + MEKINIST Across Clinical Trials*
- Across TAFINLAR + MEKINIST clinical trials (n=1076)*, 39% of patients treated with TAFINLAR + MEKINIST did not experience a pyrexia event, while 32% of patients experienced only one or two events.5
- The majority of pyrexia events were mild or moderate (Grade 1/2). Only 9% of patients treated with TAFINLAR + MEKINIST experienced Grade 3 events and 0.2% of patients experienced Grade 4 events.5
- Most pyrexia events were completely resolved with either temporary dose interruption or no dose change.5
- Only 6% of patients discontinued treatment with TAFINLAR or MEKINIST due to pyrexia.5
Single vs. multiple occurrences of pyrexia in all patients enrolled in clinical trials (n=1076)*
The data are based on a pooled analysis of pyrexia occurrence across four clinical trials* representing the largest analysis of a BRAF inhibitor + MEK inhibitor-induced pyrexia to date.4
*Pyrexia was analysed from the following clinical trials in melanoma and in metastatic non-small cell lung cancer (NSCLC): Registrational Phase II trial (NCT01336634) in metastatic non-small cell lung cancer (n=82); COMBI-AD in resected Stage III melanoma (n=435); COMBI-d in unresectable or metastatic melanoma (n=209); COMBI-v in unresectable or metastatic melanoma (n=350).
