Approval: Spexotras (EMA)
Indication: Low-grade glioma Spexotras in combination with dabrafenib is indicated for the treatment of paediatric patients aged 1 year and older with low-grade glioma (LGG) with a BRAFShow full indication

Low-grade glioma Spexotras in combination with dabrafenib is indicated for the treatment of paediatric patients aged 1 year and older with low-grade glioma (LGG) with a BRAF V600E mutation who require systemic therapy. High-grade glioma Spexotras in combination with dabrafenib is indicated for the treatment of paediatric patients aged 1 year and older with high-grade glioma (HGG) with a BRAF V600E mutation who have received at least one prior radiation and/or chemotherapy treatment.

Approval: Mekinist (EMA)
Indication: Melanoma Trametinib as monotherapy or in combination with dabrafenib is indicated for the treatment of adults and adolescents aged 12 years and older withShow full indication

Melanoma Trametinib as monotherapy or in combination with dabrafenib is indicated for the treatment of adults and adolescents aged 12 years and older with unresectable or metastatic melanoma with a BRAF V600 mutation (see sections 4.4 and 5.1). Trametinib monotherapy has not demonstrated clinical activity in patients who have progressed on a prior BRAF inhibitor therapy (see section 5.1). Adjuvant treatment of melanoma Trametinib in combination with dabrafenib is indicated for the adjuvant treatment of adults and adolescents aged 12 years and older with Stage III melanoma with a BRAF V600 mutation, following complete resection. Non-small cell lung cancer (NSCLC) Trametinib in combination with dabrafenib is indicated for the treatment of adults with advanced non-small cell lung cancer with a BRAF V600 mutation. Differentiated thyroid cancer (DTC) Trametinib in combination with dabrafenib is indicated for the treatment of adult patients with locally advanced or metastatic differentiated thyroid cancer with a BRAF V600E mutation, refractory to or not eligible for radioactive iodine (RAI) who have progressed during or after prior systemic therapy (for biomarker-based patient selection, see section 4.2).
