PRIMARY outcome

Timeframe: Baseline through Cycle 2 (21 Day Cycles)

Population: Zero participants were analyzed. This outcome was not determined because the study terminated before completion of Part A of the dose escalation period.

Population: All randomized participants who received at least one dose of study drug and had evaluable PK data.

Pharmacokinetics (PK): Maximum Concentration (Cmax) of LY3435151.

Timeframe: Baseline through Disease Progression or Death (Up to 4 Months)

Population: Zero participants were analyzed. The study was terminated early and no data was collected.

Overall response rate is the best response of complete response (CR) or partial response (PR) as classified by the independent central review according to the Response Evaluation Criteria In Solid Tumors (RECIST v1.1). CR is a disappearance of all target and non-target lesions and normalization of tumor marker level. PR is an at least 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameter) without progression of non-target lesions or appearance of new lesions. Overall response rate is calculated as a total number of participants with CR or PR divided by the total number of participants per cohort with at least 1 measurable lesion, multiplied by 100.

SECONDARY outcome

Timeframe: Baseline through Measured Progressive Disease (Up to 4 Months)

Population: Zero participants were analyzed. The study was terminated early and no data was collected.

Disease Control Rate (DCR) is the percentage of participants with a best overall response of CR, PR, or Stable Disease (SD) as per Response using RECIST v1.1 criteria. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD for target lesions, no progression of non-target lesions, and no appearance of new lesions. PD is at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions.

SECONDARY outcome

Timeframe: Date of CR or PR to Date of Objective Disease Progression or Death Due to Any Cause (Up to 4 Months)

Population: Zero participants were analyzed. The study was terminated early and no data was collected.

DOR is the time from the date of first evidence of complete response or partial response to the date of objective progression or the date of death due to any cause, whichever is earlier. CR and PR defined using the RECIST v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. If a responder was not known to have died or have objective progression as of the data inclusion cutoff date, duration of response was censored at the last adequate tumor assessment date. PD was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions.

SECONDARY outcome

Timeframe: Baseline to Date of CR or PR (Up to 4 Months)

Population: Zero participants were analyzed. The study was terminated early and no data was collected.

Time to response (TTR) is defined as the time from the date of start of treatment to the date measurement criteria for confirmed CR or PR (whichever is first recorded) are first met. For participants who are not known to have achieved CR or PR as of the data inclusion cut-off date, TTR will be censored at the date of the last objective disease assessment prior the date of any subsequent systematic anticancer therapy.

SECONDARY outcome

Timeframe: Baseline to Objective Progression or Death Due to Any Cause (Up to 4 Months)

Population: Zero participants were analyzed. The study was terminated early and no data was collected.

PFS time was measured from the date of randomization until the first radiographic documentation of progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, or death from any cause. Progressive Disease (PD) was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions. If a participant does not have a complete baseline disease assessment, then the PFS time was censored at the date of first dose, regardless of whether or not objectively determined disease progression or death has been observed for the participant. If a participant was not known to have died or have objective progression as of the data inclusion cutoff date for the analysis, the PFS time was censored at the last adequate tumor assessment date.
