Pierre Fabre receives CHMP positive opinion for Braftovi in first-line BRAF V600E-mutant colorectal cancer

Pierre Fabre Laboratories has received a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use recommending approval of Braftovi (encorafenib) in combination with cetuximab and FOLFOX for the first-line treatment of adult patients with BRAF V600E-mutant metastatic colorectal cancer, marking the first targeted therapy recommended for this setting in the EU.

The CHMP opinion will now be forwarded to the European Commission, with a final marketing authorisation decision expected later in 2026. If granted, the approval would represent a label expansion for encorafenib in the EU, where the drug has previously been authorised only for previously treated BRAF V600E-mutant metastatic colorectal cancer in combination with cetuximab alone, based on data from the BEACON CRC trial.

The filing is supported by data from the Phase III BREAKWATER trial (NCT04607421), which assessed encorafenib combined with cetuximab and mFOLFOX6 against oxaliplatin-based chemotherapy with or without bevacizumab in patients with previously untreated BRAF V600E-mutant metastatic colorectal cancer. The trial met its dual primary endpoints of objective response rate and progression-free survival. Median PFS was 12.8 months in the encorafenib arm versus 7.1 months in the control arm, corresponding to a hazard ratio of 0.53 (95% CI, 0.41 to 0.68). The company also reported a 51% reduction in the risk of death compared with chemotherapy with or without bevacizumab, though full overall survival statistics were not disclosed in the press release.

BRAF V600E mutations occur in approximately 8% to 12% of metastatic colorectal cancer patients and are associated with an aggressive disease course, right-sided tumour predominance, and historically poor outcomes on standard chemotherapy. Prior to the approval of encorafenib-based regimens, median overall survival in this population on first-line chemotherapy was generally below 12 months. The BREAKWATER data, which informed a US FDA accelerated approval in December 2024 and a subsequent full traditional approval in February 2026, now underpin the European regulatory recommendation.

Encorafenib is an oral small-molecule inhibitor of mutant BRAF kinase. In colorectal cancer, BRAF inhibition alone has limited efficacy due to EGFR-mediated reactivation of the MAPK signalling pathway — a feedback mechanism that does not occur in melanoma and that drove the rational design of the encorafenib-plus-cetuximab combination. The addition of mFOLFOX6 chemotherapy to that doublet was investigated in BREAKWATER as a means of further deepening response in the first-line setting, where tumour burden and disease tempo are typically high.

The competitive context for this indication remains narrow. No other targeted agent has received regulatory approval specifically for first-line BRAF V600E-mutant metastatic colorectal cancer in the EU. In the MSI-H/dMMR subpopulation, which accounts for roughly 20 to 30% of BRAF V600E-mutant cases, immune checkpoint inhibitors including pembrolizumab are approved and represent an alternative first-line strategy, though optimal sequencing with encorafenib-based therapy in that subset remains an open clinical question. For the larger MSS/pMMR population, no immunotherapy option is currently validated, and the encorafenib triplet addresses a setting with limited alternatives.

In the US, the marketing authorization holder is Array BioPharma, a Pfizer subsidiary. In the EU, Pierre Fabre holds the marketing authorization for Braftovi under EMA product number EMEA/H/C/004580. The two companies operate independently in their respective regulatory jurisdictions, and the CHMP positive opinion is specific to Pierre Fabre's EU application.

The broader development landscape for BRAF V600E-mutant metastatic colorectal cancer continues to evolve. Active Phase II programmes include an investigation of encorafenib, cetuximab, and pembrolizumab in MSI-H/dMMR first-line patients (NCT05217446), as well as early-phase work with HLX208, an investigational BRAF V600E inhibitor being developed by Shanghai Henlius Biotech in combination with cetuximab. These programs reflect ongoing efforts to optimise the BRAF-plus-EGFR backbone and to explore immunotherapy integration in biomarker-defined subsets.

Resistance to encorafenib-based regimens remains a clinical challenge. Primary resistance affects a subset of patients through MAPK pathway bypass mechanisms, and acquired resistance is nearly universal among initial responders, with no approved targeted option available after progression on first-line encorafenib therapy. Post-progression outcomes on available options such as regorafenib or trifluridine/tipiracil remain poor, representing a material unmet need in the field.

The European Commission is not obligated to follow CHMP recommendations but does so in the large majority of cases. A formal decision is anticipated within approximately two months of the positive opinion, which was adopted on May 21, 2026.
