Dabrafenib and Trametinib Treatment in Patients With Locally Advanced or Metastatic BRAF V600-Mutant Anaplastic Thyroid Cancer.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2018, 01-01, Volume: 36, Issue:1

    Purpose We report the efficacy and safety of dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) combination therapy in BRAF V600E-mutated anaplastic thyroid cancer, a rare, aggressive, and highly lethal malignancy with poor patient outcomes and no systemic therapies with clinical benefit. Methods In this phase II, open-label trial, patients with predefined BRAF V600E-mutated malignancies received dabrafenib 150 mg twice daily and trametinib 2 mg once daily until unacceptable toxicity, disease progression, or death. The primary end point was investigator-assessed overall response rate. Secondary end points included duration of response, progression-free survival, overall survival, and safety. Results Sixteen patients with BRAF V600E-mutated anaplastic thyroid cancer were evaluable (median follow-up, 47 weeks; range, 4 to 120 weeks). All patients had received prior radiation treatment and/or surgery, and six had received prior systemic therapy. The confirmed overall response rate was 69% (11 of 16; 95% CI, 41% to 89%), with seven ongoing responses. Median duration of response, progression-free survival, and overall survival were not reached as a result of a lack of events, with 12-month estimates of 90%, 79%, and 80%, respectively. The safety population was composed of 100 patients who were enrolled with seven rare tumor histologies. Common adverse events were fatigue (38%), pyrexia (37%), and nausea (35%). No new safety signals were detected. Conclusion Dabrafenib plus trametinib is the first regimen demonstrated to have robust clinical activity in BRAF V600E-mutated anaplastic thyroid cancer and was well tolerated. These findings represent a meaningful therapeutic advance for this orphan disease.

Sudden elevation of plasma D-dimer levels induced by the combination therapy of dabrafenib and trametinib: Report of two cases.
    The Journal of dermatology, 2019, Volume: 46, Issue:4

    The combination therapy of dabrafenib and trametinib revolutionized the treatment for BRAF V600-mutated melanoma. Various adverse events have been reported for this treatment, most notably fever. Herein, we report two cases of novel an adverse event, namely sudden and significant elevation of plasma D-dimer level induced by this therapy. In the first case, the remarkable elevation of plasma D-dimer level up to 87.4 mg/dL was noted on day 11, and in the second case, the plasma D-dimer level reached 125.5 mg/dL on day 25. In both cases, D-dimer levels gradually decreased after the cessation of this therapy. Although the exact cause is not clear, we assume two possible hypotheses: the first is that the combination therapy may induce disseminated intravascular coagulation, and the second is that the therapy induced pathological condition of secondary thrombotic microangiopathies. Our cases suggest that this thrombotic adverse event should not be overlooked, and coagulation parameters need to be monitored during the course of this treatment.

Dabrafenib and trametinib, alone and in combination for BRAF-mutant metastatic melanoma.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2014, Apr-15, Volume: 20, Issue:8

    Dabrafenib and trametinib were approved for use as monotherapies in BRAF-mutant metastatic melanoma by the U.S. Food and Drug Administration (FDA) in 2013, and most recently, their use in combination has received accelerated FDA approval. Both drugs target the mitogen-activated protein kinase (MAPK) pathway: dabrafenib selectively inhibits mutant BRAF that constitutively activates the pathway, and trametinib selectively inhibits MEK1 and MEK2 proteins activated by RAF kinases. The phase III study of dabrafenib in BRAF(V600E) metastatic melanoma reported rapid tumor regression in most patients and a 59% objective RECIST response rate. The median progression-free survival (PFS) and overall survival (OS) were improved compared with dacarbazine. Toxicities were well tolerated and different from those reported for vemurafenib, the first FDA-approved BRAF inhibitor. Efficacy has been demonstrated in other BRAF-mutant genotypes. The phase III study of trametinib in BRAF inhibitor-naïve patients with BRAF(V600E) or BRAF(V600K) also showed benefit with a prolonged median PFS and OS compared with chemotherapy. Trametinib is ineffective in patients who have progressed on BRAF inhibitors. A phase II trial of combined dabrafenib and trametinib demonstrated higher response rates and longer median PFS than dabrafenib monotherapy, with less cutaneous toxicity. Here, we review the clinical development of both drugs as monotherapies and in combination, and discuss their role in the management of BRAF-mutant melanoma.
