effects of fluconazole and itraconazole cyp3a-mediated inhibition on the pharmacokinetics, safety, and tolerability of mln4924 in participants with advanced solid tumors

Conditions: Advanced Solid Tumors

Summary: the primary purpose of this study is to assess the effect of multiple-dose administration of fluconazole on the single-dose intravenous (iv) pharmacokinetics (pk) of mln4924; and to assess the effect of multiple-dose administration of itraconazole on the single-dose iv pk of mln4924.

the drug being tested in this study is mln4924. mln4924 is being evaluated to assess drug-drug interactions (ddis) with the moderate and strong cyp3a inhibitors, fluconazole and itraconazole, respectively, in participants with advanced solid tumors. this study will look at the blood concentrations of mln4924 as it relates to treatment with fluconazole and itraconazole. the study will enroll approximately 52 participants. in part a, participants will be administered mln4924 via a 1-hour (+- 5 minutes) intravenous (iv) infusion in combination with either fluconazole or itraconazole administered orally. after participants complete part a, they will have the opportunity to begin treatment in part b. in part b, participants will be administered mln4924 via a 1-hour (+- 5 minutes) iv infusion in combination with either docetaxel or carboplatin + paclitaxel, the three of which would also be administered intravenously. this multi-center trial will be conducted in the united states. participation in part a of this study will include a screening visit and two weeks of treatment; participation in part b of this study will include up to an 8-week drug washout period (from last dosing in part a) and treatment until participants experience symptomatic deterioration, progressive disease, until treatment is discontinued for another reason, or until the study is stopped.
