Spots Global Cancer Trial Database for Study to Investigate the Objective Response Rate of Dabrafenib in Combination With Trametinib in Subjects With BRAF V600 Mutation-Positive Melanoma

Study Description

Brief Summary: This was a single-arm, open-label, multi-center, Phase II study to evaluate dabrafenib and trametinib combination therapy in subjects with BRAF V600 mutation-positive, unresectable or metastatic Acral lentiginous or cutaneous melanoma. This study evaluated the objective response rate (ORR), progression free survival (PFS), duration of response, overall survival (OS), safety and efficacy, to assess steady state (all subjects) exposure to dabrafenib, dabrafenib metabolites, and trametinib and characterize the population pharmacokinetics (PK) and pharmacodynamics (PD) of dabrafenib and trametinib. Enrolled subjects were administered dabrafenib 150 milligram (mg) orally twice daily and trametinib 2 mg orally once daily. Treatment continued until disease progression, death, unacceptable toxicity, or withdrawal of consent, or study closure. After treatment discontinuation, subjects were followed for survival and disease progression as applicable.

Detailed Description: This was an open-label, single arm, Phase IIA, multi-center study to evaluate the Objective response rate (ORR) of dabrafenib and trametinib combination therapy in East Asian subjects that have BRAF V600 mutationpositive Stage IIIC (unresectable) or Stage IV (metastatic) acral lentiginous melanoma (ALM) or cutaneous melanoma. All subjects enrolled received oral dabrafenib 150 mg bid in combination with oral trametinib 2 mg once daily. A primary analysis presented the efficacy, safety and pharmacokinetics (PK) data up to the data cut-off date of 23-Feb-2018. Based on these results, dabrafenib and trametinib combination was approved in the People's Republic of China (PRC) for the treatment of BRAF-mutation positive unresectable or metastatic melanoma. Data from Mainland Chinese subjects from 01-Jul-2019 onwards are not included due to local regulations in China. Subjects continued study treatment until disease progression, death, unacceptable toxicity, withdrawal of consent, or study completion. After treatment discontinuation, subjects went into follow-up for survival and disease progression as applicable. Subjects could continue study treatment after disease progression if they achieved clinical response per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 or stable disease with tumour reduction; had no overt signs of toxicity; had Eastern Cooperative Oncology Group (ECOG) performance status of ≤1 and did not require immediate surgical or radiological intervention.
