The main aim of this study are to check for side effects from TAK-853, check how much TAK-853 participants can receive without getting side effects from it, check how well TAK-853 controls symptoms, and to check how much TAK-853 stays in their blood over time. The study will be conducted in two phases including Phase 1 Part and Phase 2 Part. In Phase 1 Part, the participants will stay in the hospital for 3 days at least after their 1st injection for some tests and to check for any side effects from their treatment. In Phase 2 Part, participants will visit their study hospital for multiple times. In both phases, the participants will receive TAK-853 on the first days of each 3-week cycle. The participant will be in the study for about 9 months in Phase 1 Part and for about 24 months in Phase 2 Part. The study doctors will check for side effects from the study treatments.

If re-treatment was not initiated within 14 days due to adverse event (AE) related to protocol treatment; 2. Grade 4 neutropenia for more than 7 days; 3. Grade 3 or 4 neutropenia with single temperature reading \>= 38.3-degree Celsius (°C) or sustained temperature reading of greater than (\>) 38°C for \>1 hour; 4. Platelet counts decreased of Grade 3 requiring platelet transfusion or blood platelet decreased of Grade 4; 5. Grade 3 or higher non-hematologic toxicity that was considered clinically significant, except following cases, AEs related to underlying disease, Alopecia, Grade 3 fatigue, Lymphopenia unless accompanied by clinically significant infection, isolated and asymptomatic Grade 3 abnormalities in biochemistry laboratory values that last for less than and equal to (\<=) 7 days including electrolyte abnormalities.
Time frame: Up to Cycle 1 (up to 21 days)
Phase 1: Number of Participants With Treatment-emergent Adverse Events (TEAEs)
An AE means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. This includes any newly occurring event, or a previous condition that has increased in severity or frequency since the administration of study drug.
Time frame: From start of study drug up to 30 days after last dose (up to 3.7 months)
Phase 1: Number of Participants With Grade 3 or Higher TEAEs by Severity
The severity grade was evaluated as per the NCI CTCAE Version 5.0, where Grade 1 scales as Mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2 scales as Moderate (minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living \[ADL\]); Grade 3 was severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living (ADL), Grade 4 was life-threatening consequences; urgent intervention indicated, and Grade 5 was death related to AE. TEAEs were AEs with an onset date on or after the first dose of study drug, and within 30 days of the last dose of study drug or prior to the start of a new anti-cancer treatment, whichever occurs first.
Time frame: From start of study drug up to 30 days after last dose (up to 3.7 months)
Phase 1: Number of Participants With Serious TEAEs
