About
The purpose of this study is to determine the safety, tolerability, maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of TAK-659 when administered in East Asian participants with NHL who do not have an effective standard treatment available and to characterize the plasma and urine pharmacokinetic (PK) of TAK-659 in East Asian participants with NHL.
Full description
The drug being tested in this study is called TAK-659. TAK-659 is being tested to treat people who have NHL or people who have relapsed and/or refractory NHL. This study will assess the safety, tolerability, PK, and preliminary efficacy of single-agent TAK-659 in East Asian participants with NHL.
The study will enroll approximately 33 to 47 participants, including at least 6 Japanese at RP2D dose level. Participants will be assigned to one of the following treatment groups:
Dose Escalation Part: TAK-659 Expansion Part: TAK-659 RP2D
This multi-center trial will be conducted in Japan and Republic of Korea. The maximum duration of participation in dose escalation part of the study is up to 12 months, unless in the opinion of the investigator and sponsor the participant would derive benefit from continued therapy beyond 12 months. In expansion part, participants who stop treatment for any other reason other than PD will continue to have PFS follow-up at the site every 2 months from the last dose of study drug up to 6 months or until PD. Participants will be followed 28 days after last dose of study drug or until the start of subsequent antineoplastic therapy, whichever occurs first, for a follow up assessment.

Inclusion criteria
To be enrolled to the dose escalation part, participants must have histologically or cytologically confirmed diagnosis of NHL for which no effective standard treatment is available.
To be enrolled in the expansion part, participants must meet the following criteria:
Measurable disease per IWG 2007 criteria.
Eastern Cooperative Oncology Group performance status score of 0 or 1.
Life expectancy of longer than 3 months.
Adequate organ function, including the following:
Exclusion criteria
Received medications, supplements, or food/beverages that are P-glycoprotein (P-gp) inhibitors or inducers or strong cytochrome P450 (CYP) 3A inhibitors or inducers within a certain time frame prior to the first dose of study drug. Depending on the substance, the washout period for P-gp inhibitors or inducers or strong CYP3A inhibitors or inducers will be either 7 days or 5 times the half-life (half-life is related to the time required for elimination from the body). The washout period for grapefruit containing food or beverages is 5 days.
