- Brief Summary
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetic (PK) profile of trebananib (AMG 386) after intravenous administration in adult Japanese participants with advanced solid tumors.
- Detailed Description
The drug being tested in this study is called trebananib (AMG 386). Trebananib (AMG 386) is being tested to treat people with advanced solid tumors.
This study will look at the safety, tolerability and pharmacokinetic (PK) profile of trebananib and response to treatment.
The study will enroll approximately 18 participants. Once enrolled, participants will be assigned sequentially into 1 of the 3 cohorts:
* Trebananib 3 milligram/kilogram (mg/kg),
* Trebananib 10 mg/kg,
* Trebananib 30 mg/kg.
All participants will receive trebananib via 60 minute intravenous infusion. This study will be conducted in Japan. The overall time to participate in this study is 14 weeks or more. Participants will attend the end-of-treatment visit 28 days after the last dose of study drug.

- Primary Outcome Measures
Name Time Method Cmin: Minimum Observed Serum Trough Concentration for AMG 386 After Week 4 Dose Week 4: 168 hours after end of infusion Cmin was the observed serum concentration at 168 hours postdose.
Vss: Volume of Distribution at Steady State for AMG 386 Week 4: predose, 1, 2, 6, 24, 48, 96, 168 and 264 hours after end of infusion Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Vss is the apparent volume of distribution at steady-state, estimated as: Vss = MRTinf \*CLss, where MRTinf is mean residence time of drug extrapolated to infinity and CLss is the systemic clearance at the steady state. Vss was normalized to participant's body weight.
Terminal Phase Elimination Half-life (T1/2) for AMG 386 Week 4: predose, 1, 2, 6, 24, 48, 96, 168 and 264 hours after end of infusion Terminal phase elimination half-life (T1/2) is the time required for half of the drug to be eliminated from the serum.
Systemic Clearance at Steady State (CLss) for AMG 386 Week 4: predose, 1, 2, 6, 24, 48, 96 and 168 hours after end of infusion CL is a quantitative measure of the rate at which a drug substance is removed from the body. Systemic clearance at steady state (CLss) was calculated as the ratio of dose administered to AUC (0 - tau), where AUC (0 - tau) is the area under the serum concentration-time curve during a dosing interval, where tau is the length of the dosing interval (168 hours for once weekly regimen). CLss was normalized to participant's body weight.
Accumulation Ratio (AR) for AMG 386 Week 1: predose, 1, 2, 6, 24, 48 and 96 hours after end of infusion, Week 2: predose, Week 4: predose, 1, 2, 6, 24, 48, 96, and 168 hours after end of infusion Accumulation ratio (AR) was calculated by dividing the individual AUC (0-tau) value at Week 4 by the corresponding individual AUC (0-tau) value at Week 1.
Number of Participants With Dose Limiting Toxicity (DLT) Day 1 up to Day 28 DLT is defined as any treatment-related, grade 4 or higher hematologic or grade 3 or higher non-hematologic toxicity (according to the Common Terminology Criteria for Adverse Events \[CTCAE\] version 3.0; hematologic toxicity means any toxicities which are categorized in blood/bone marrow category of CTCAE), except for aspartate aminotransferase (AST), alanine aminotransferase (ALT) and infusion reaction, occurred during the first 28 days after the initial administration (before examination on Study Day 29).

Number of Participants Reporting One or More Treatment-emergent Adverse Events (AEs) and Serious Adverse Event (SAEs) Baseline up to 4 weeks after the last dose of study drug, where last dose was given up to Week 249 An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. Treatment emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event.

- Secondary Outcome Measures
Name Time Method Number of Participants With Best Overall Response Baseline, assessed every 8 weeks up to 4 weeks after the last dose of study drug, where last dose was given up to Week 249 Best overall response for a participant is the best observed post-baseline disease response as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.0 criteria. Complete Response (CR): disappearance of all target lesions, non-target lesions and normalization of tumor marker level. Partial Response (PR): at least 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the baseline smallest sum of longest diameter; persistence of 1 or more non-target lesion(s) or maintenance of tumor marker level above the normal limits. PD: at least 20% increase in the sum of the longest diameter of target lesions, taking as reference the baseline smallest sum of longest diameter or appearance of 1 or more new lesions or unequivocal progression of existing non-target lesions.
Percentage of Participants With Objective Response Baseline, assessed every 8 weeks up to 4 weeks after the last dose of study drug, where last dose was given up to Week 249 Objective response rate defined as the rate of participants with CR or PR based on RECIST 1.0 criteria. CR: disappearance of all target lesions, non-target lesions and normalization of tumor marker level. PR: at least 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.
Time to Progression (TTP) Baseline, assessed every 8 weeks up to 4 weeks after the last dose of study drug, where last dose was given up to Week 249 TTP is defined as the time from the date of first administration of study treatment to the date of first documentation of PD or death caused by progression. For participants who did not have a documented PD or died owing to causes other than progression, TTP was censored at the time of last response assessment. PD is defined as at least 20% increase in the sum of the longest diameter of target lesions, taking as reference the baseline smallest sum of longest diameter or appearance of 1 or more new lesions or unequivocal progression of existing non-target lesions.
Percent Change From Baseline to Post-baseline in the Sum of the Longest Diameters of Tumor Baseline, assessed every 8 weeks up to 4 weeks after the last dose of study drug, where last dose was given up to Week 249 The percent change from baseline to post-baseline is the largest percent reduction from baseline among all post-dose measures of the sum of the longest diameter of the tumor burden.
