主要结局
Number of Participants With Toxicity or Intolerable Dose Criteria
时间窗: Baseline up to Day 304/End of Treatment (ET)
The dose was considered intolerable if a participant developed either ocular toxicity or other toxicity as per Common Terminology Criteria for Adverse Events (CTCAE) or based on the investigator's discretion. Ocular toxicity included: Grade \>= 3 (retinopathy, retinal detachment, cataract formation, optic disk edema, keratitis, vitreous hemorrhage and uveitis) and acute vision loss of greater than 3 lines of vision up to and including 140 days after the first dose. Other toxicity included serious adverse event (SAE), Grade \>= 3 (increased liver transaminases, encephalopathy/leukoencephalopathy, diarrhea, enteritis or nausea, prolongation of QT interval \[Fridericia's correction\]), Grade \>=2 (central nervous system hemorrhage, decreased total leukocyte count, increased serum creatinine) and thrombocytopenia \<100\*10 9 /liter.
Number of Participants With Treatment Emergent Adverse Events (TEAEs) Categorized by Severity
时间窗: Baseline up to Day 304/ET
AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent are events between first dose of study drug and up to Day 304/ET that were absent before treatment or that worsened relative to pretreatment state. AE was assessed according to severity; Grade 1 (mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated), Grade 2 (moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living \[ADL\]), Grade 3 (severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL), Grade 4 (life-threatening consequences; urgent intervention indicated) and Grade 5 (death related to AE).
Number of Participants With Ocular Treatment Emergent Adverse Events (TEAEs) Categorized by Causal Relationship to Study Drug
时间窗: Baseline up to Day 304/ET
AE was any untoward medical occurrence in participant who received study drug without regard to causal relationship and drug-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent are events between first dose of study drug and up to Day 304/ET that were absent before treatment or that worsened relative to pretreatment state. Ocular AEs were events which were localized in the ocular region. Ocular AEs reported as related and non-related to study drug.
Number of Participants With Systemic Treatment Emergent Adverse Events (TEAEs) Categorized by Severity
时间窗: Baseline up to Day 304/ET
AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent are events between first dose of study drug and up to Day 304/ET that were absent before treatment or that worsened relative to pretreatment state. Systemic AE were events which were not localized but occurred throughout the systemic circulation and was assessed according to severity; Grade 1 (mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated), Grade 2 (moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL), Grade 3 (severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL), Grade 4 (life-threatening consequences; urgent intervention indicated) and Grade 5 (death related to AE).
