Conditions

Solid Tumors

Brief summary

The purpose of this study is to evaluate the effect of trametinib once daily on the pharmacokinetics (PK) of a daily dosing oral contraceptives (OCs) containing norethindrone (NE) and ethinyl estradiol (EE) in female patients with solid tumors. The PK of trametinib and its metabolite M5 will also be assessed.

Interventions

DRUGTrametinib

Each tablet is 2mg trametinib to be taken orally once daily.

DRUGOral Contraceptive (1mg norethindrone, 0.035mg ethinyl estradiol)

Combined oral contraceptive to be taken orally once daily.

Exclusion criteria

) that is not responsive to standard therapy(ies) or for which there is no approved therapy. * Meets one of the following criteria: Is currently on a stable regimen of an oral contraceptive containing 1mg NE and 0.035mg EE, or Is willing to switch to a regimen of an oral contraceptive containing 1mg NE and 0.035mg EE from a stable regimen of an alternate OC, or Is willing to start a regimen of an oral contraceptive containing 1mg NE and 0.035mg EE. * Meets one of the following criteria: Is post-menopausal, or, Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective methods of contraception during dosing and for four months after stopping medication. * Has no prior treatment-related toxicities \>Grade 1 (except alopecia) at the time of enrolment. * Patient must meet the following laboratory values at the screening visit: Absolute Neutrophil Count ≥1.5 x 109/L. Platelets ≥75 x 109/L. Hemoglobin (Hgb) ≥9 g/dL. Serum creatinine \<1.5 mg/dL. Total bilirubin ≤1.5 x upper limit of normal (ULN) (isolated bilirubin \>1.5x ULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%). Aspartate transaminase (AST) ≤ 3.0 x ULN, except for patients with liver metastasis, who may only be included if AST ≤5.0 x ULN. Alanine transaminase (ALT) ≤ 3.0 x ULN, except for patients with liver metastasis or tumor infiltration, who may only be included if ALT ≤5.0 x ULN. Prothrombin time (PT)/International normalized ratio (INR) and Partial thromboplastin time (PTT) ≤1.5xULN. Note: patients receiving therapeutic anticoagulation agents prior screening are permitted. Albumin 2.5 g/dL. * Patient has an Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
