A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher, including death, unless clearly and incontrovertibly assessed as due to disease, disease progression, inter-current illness/injury, concomitant medications, or extraneous causes, that occurs within the first 28 days of treatment with IEV407 in the dose escalation parts or in the expansion part of IEV407 in combination with fulvestrant with the exceptions described in the study protocol.

Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Up to approximately 2 years

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

Frequency of dose interruptions, reductions and discontinuations
Up to approximately 2 years

Number of participants with dose adjustments (interruptions, reductions, or permanent discontinuation) as a measure of tolerability.

Dose intensity
Up to approximately 2 years

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

Secondary Endpoints

Best Overall Response (BOR)
Up to approximately 2 years
Overall Response Rate (ORR)
Up to approximately 2 years
Disease Control Rate (DCR)
Up to approximately 2 years
