Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01725100 ↗	A Study to Determine the Relative Bioavailability of the MEK Inhibitor, Trametinib, in Subjects With Solid Tumor Malignancies	Completed	GlaxoSmithKline	Phase 1	2013-02-05	This is an open-label, randomized, single-dose, 2-treatment, 2-period, 2-way crossover study with incomplete wash-out in subjects with solid tumors to determine the relative bioavailability of test formulation with lower dimethyl sulfoxide (DMSO) content as compared with standard reference formulation trametinib. Approximately 18 subjects will be randomized to receive either a single dose of Treatment A (standard target DMSO content [theoretical 11.3%] formulation of GSK1120212B) or a single dose of Treatment B (lower DMSO Content [approximately 9.5%] formulation of GSK1120212B) followed by a 7 day incomplete wash-out period, then a single dose of the other treatment. Administration of the dose under fasted conditions in Periods 1 and 2 will be only on Day 1 followed by 7 days of serial blood sampling for PK analysis of plasma trametinib. Safety assessments, including assessment of AEs, clinical laboratory (hematology and clinical chemistry) and vital signs, will be made throughout the study. After a subject completes the study, he or she may be eligible to enter study MEK114375, an open-label rollover study of trametinib (no wash-out period or follow-up visit required) and continue receiving trametinib. For those subjects who wish to discontinue or complete the current study and choose not enter the rollover study, a follow-up visit should be performed within 21 days after receiving the last dose of study treatment.
NCT01902173 ↗	Uprosertib, Dabrafenib, and Trametinib in Treating Patients With Stage IIIC-IV Cancer	Active, not recruiting	GlaxoSmithKline	Phase 1/Phase 2	2013-07-19	This phase I/II trial studies the side effects and the best dose of uprosertib when given together with dabrafenib and trametinib and to see how well they work in treating patients with stage IIIC-IV cancer.

NCT02101788 ↗	Trametinib in Treating Patients With Recurrent or Progressive Low-Grade Ovarian Cancer or Peritoneal Cavity Cancer	Active, not recruiting	NRG Oncology	Phase 2/Phase 3	2014-04-11	This phase II/III trial studies how well trametinib works and compares it to standard treatment with either letrozole, tamoxifen, paclitaxel, pegylated liposomal doxorubicin, or topotecan in treating patients with low-grade ovarian cancer or peritoneal cavity cancer that has come back (recurrent), become worse (progressive), or spread to other parts of the body. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether trametinib is more effective than standard therapy in treating patients with ovarian or peritoneal cavity cancer.

What is Trametinib Dimethyl Sulfoxide?

Trametinib (brand name Mekinist) is an FDA-approved oral MEK1/2 inhibitor used primarily in BRAF-mutant melanoma and other solid tumors. Dimethyl Sulfoxide (DMSO) is a solvent with known skin-penetrating properties, often used in drug formulations for enhanced delivery or stability.

Trametinib Dimethyl Sulfoxide (hereafter, TDSO) refers to a proprietary formulation designed to improve pharmacokinetics, delivery to target tissues, or as part of preclinical research trajectories. Its commercialization status remains under investigation, with clinical studies exploring safety, efficacy, and novel indications.
