Study Endpoints

Primary Endpoints

Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Up to approximately 24 months

Number of participants with AEs and SAEs, including changes in laboratory values, vital signs and echocardiograms (ECGs) qualifying and reported as AEs.

Incidence of Dose Limiting Toxicities (DLTs)
21 days

Number of participants with DLTs. A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher, unless clearly and incontrovertibly assessed as due to underlying disease, disease progression, or intercurrent illness, that occurs within the first 21 days of treatment with TRB191. Other clinically significant toxicities may be considered DLTs, even if not CTCAE grade 3 or higher.

Frequency of dose interruptions and reductions
Up to approximately 24 months

Number of participants with dose adjustments (interruptions and reductions as a measure of tolerability.

Dose intensity
Up to approximately 24 months

Dose intensity defined as the ratio of actual cumulative dose received and actual duration of exposure.

Secondary Endpoints

Maximum serum concentration (Cmax) of TRB191
From pre-dose up to 120 or 240 hours post-dose
Time to reach maximum serum concentration (Tmax) of TRB191
From pre-dose up to 120 or 240 hours post-dose
Arean under the serum concentration-time curve (AUC) of TRB191
From pre-dose up to 120 or 240 hours post-dose
