A Study of the Safety and Pharmacokinetics of RO6839921, An MDM2 Antagonist, in Patients With Advanced Cancers, Including Acute Myeloid Leukemia.
This open label, Phase I study of RO6839921 is a dose-escalation study with two arms. Prior to investigations in either arm, patients in a single cohort, Cohort 0, will receive non-escalating, intravenous (IV) doses of RO6839921 daily on Days 1-5 of a 28-day cycle. Interim PK and safety data from this cohort will be evaluated before initiating dose-escalation.
In arm A, RO6839921 will be given to patients with advanced solid tumor malignancies. In Arm B, RO6839921 will be given to patients with relapsed/refractory acute myeloid leukemia (AML). The arms will escalate independently. Escalation will begin in solid tumor patients (Arm A) in single patient cohorts, using a new Continual Reassessment Method (n-CRM). Escalation for AML patients will be initiated at or below the dose level that causes >/= Grade 2 hematologic side effects in Arm A. Escalation in AML patients will follow a rolling 6 design.
In both arms, RO6839921 will be administered by IV infusion on Days 1-5 of 28-day cycles.
There will be no intrapatient dose escalation. All patients may be treated until disease progression/relapse or unacceptable toxicity.

|Experimental: Acute myeloid leukemia patients||
Escalating IV doses of RO6839921 in AML patients. Escalation will follow an adapted rolling 6 design. Starting dose </= dose inducing Grade 2 toxicity in patients with solid tumors. RO6839921 will be given on Days 1-5 of 28-day cycles. Treatment will continue until disease progression, unacceptable toxicity or study discontinuation.
|Experimental: Cohort 0||
Non-escalating IV doses given on Days 1-5 of Cycle 1.
|Experimental: Solid tumor patients||
Escalating IV doses of RO6839921 in solid tumor patients. Dose escalation will be calculated using the new Continual Reassessment Method (nCRM). RO6839921 will be given on Days 1-5 of 28-day cycles. Treatment will continue until disease progression, unacceptable toxicity or study discontinuation.
