Brief Summary

This is a multicenter phase II clinical study of trametinib in combination with GSK2141795 in patients with BRAF wild-type mutation melanoma. All patients will receive continuous dosing of trametinib (2 mg) in combination with GSK2141795 (25 mg) oral daily until progression of disease, withdrawal of consent, or the development of intolerable treatment associated toxicity. Imaging (CT or MRI) will be performed within 7 days prior to day 1 of Odd Cycles, starting with Cycle 3. Patients may continue treatment with trametinib in combination with GSK2141795 on trial until disease progression or the development of unacceptable toxicity that does not improve with maximal supportive care or dose reduction per protocol. Treatment-associated adverse events will be assessed based on clinical and laboratory findings using the Common Toxicity Criteria for Adverse Events, version 4.0. Adverse event (AE) assessments will be performed every week through cycle 3 day 1, and on day 1 for every cycle thereafter. AEs and Serious adverse events (SAE)s will be monitored by UCSF's Data Safety Monitoring Committee. Safety assessments will include medical history, physical examination, Complete Blood Count (CBC) with differential, chemistries panel, thyroid function and pregnancy tests, ECGs, and ophthalmology evaluations. Screening assessments will also include a transthoracic echocardiogram or multiple-gated acquisition (MUGA) scan, and brain imaging. It is estimated that 48 patients will complete the study.

Outcome Measures

Primary Outcomes (1)

• Objective Response Rate (ORR)

  Only those participants who have measurable disease present at baseline, have received at least one cycle of therapy, and have had their disease re-evaluated will be considered evaluable for response These participants will have their response classified according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) method, where the baseline target lesion sum of longest diameter (LD) will be used as reference by which to characterize the objective tumor response. An objective response is defined as an overall response of complete response (CR), partial response (PR), or stable disease (SD) with a confirmatory scan or evaluation at time of final disease response determination.

  Up to 2 years from beginning of therapy

Secondary Outcomes (4)

• Progression-Free Survival of Patients Treated With the Combination of Trametinib and GSK 2141795

  Up to 2 years from beginning of therapy

• Overall Survival of Patients Treated With the Combination of Trametinib and GSK 2141795

  Up to 2 years from beginning of therapy

• Time-to-Progression (TTP) of Patients Treated With the Combination of Trametinib and GSK 2141795

  Up to 2 years from beginning of therapy

• Number of Severe Adverse Events (Grade 3 and 4) Reported by Patients Related With the Treatment of Trametinib and GSK2141795.

  Up to 2 years from beginning of therapy

EXPERIMENTAL

Trametinib (GSK1120212) * Oral * 2 mg * Daily * Number of Cycles: until progression or unacceptable toxicity develops GSK2141795 * Oral * 25 mg * Daily * Number of Cycles: until progression or unacceptable toxicity develops

Drug: Trametinib (GSK1120212); Drug: GSK2141795

Interventions

Trametinib (GSK1120212) DRUG

Trametinib is a highly selective allosteric inhibitor of MEK1 and MEK2 activation and kinase activity.

Also known as: MEKINIST

GSK2141795 DRUG

GSK 2141795 is an ATP competitive subnanomolar pan-AKT inhibitor. In order to measure the true potency of GSK 2141795, potency (Ki\*) values were determined in a filter binding assay using lower enzyme concentrations (0.1, 0.7, and 0.2 nM for human AKT1, AKT2, and AKT3, respectively). Using a sandwich ELISA, GSK 2141795 inhibited phosphorylation of GSK-3β in BT474 and LNCaP cell lines with EC50 values of 143 and 34 nM, respectively. Since phosphorylation of GSK-3β can be modulated by other enzymes (PKA, PKC, and RSK),cellular activity of GSK 2141795 was evaluated using a phospho-PRAS40 ELISA. GSK 2141795 inhibited the phosphorylation of PRAS40 with EC50 values of 39 and 55 nM for BT474 and LNCaP cells, respectively.
