Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Phase 1: Number or Participants With Dose Limiting Toxicities (DLTs) | Cycle 1 (21 Day Cycle) | DLT is defined as an event that is clinically significant and not clearly related to disease progression or intercurrent illness that occurred within the DLT observation period of the Cycle 1 timeframe. |
| Phase 2: Overall Response Rate (ORR): Percentage of Participants Who Achieve Complete Response (CR) or Partial Response (PR) in Colorectal Cancer (CRC) Cohorts and Other Tumors Cohort | Baseline through Measured Progressive Disease | ORR is defined as percentage of participants who achieved a CR or PR out of all the participants treated. Tumor responses were measured and record using Response Evaluation Criteria in Solid Tumors v1.1 (RECIST) v1.1 guidelines. CR is defined as the disappearance of all targeted and non-target lesions and no appearance of new lesions. PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions and no appearance of new lesions. |
| Phase 2: Progression-Free Survival (PFS) Non-Small Lung Cancer (NSCLC Cohorts) | Baseline to Objective Progression or Death Due to Any Cause | PFS was defined as the time from study enrollment (for non-randomized cohorts)/ the time from randomization (for randomized cohorts) to the first observation of progressive disease (PD) or death without documented disease progression per RECIST V1.1 criteria. |

| Phase 1: PK: Average Concentration at Steady State of LY3499446 in Combination With Erlotinib | Predose Cycle 1 Day 1 through Cycle 3 Day 1 (21 Day Cycles) | PK: Average Concentration at Steady State of LY3499446 in Combination with Erlotinib |
| Phase 1: ORR: Percentage of Participants Who Achieve CR or PR | Baseline through Measured Progressive Disease (Up to 11 Months) | ORR is defined as percentage of participants who achieved a CR or PR out of all the participants treated. Tumor responses were measured and record using Response Evaluation Criteria in Solid Tumors v1.1 (RECIST) v1.1 guidelines. CR is defined as the disappearance of all targeted and non-target lesions and no appearance of new lesions. PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions and no appearance of new lesions. |
| Phase 1: Pharmacokinetics (PK): Average Concentration of LY3499446 | Cycle 1 Day 1: Predose, 0.5, 1, 1.5, 2, 3, 4, 8, 24 hours post-dose | Average concentration after the first dose of LY3499446. |
| Phase 1: Duration of Response (DoR) | Date of CR or PR to Date of Disease Progression or Death Due to Any Cause (Up to 11 Months) | DoR was defined as the time from the date measurement criteria for CR or PR (whichever is first recorded) are first met until the first date that disease is recurrent or objective progression is observed, per RECIST v1.1 criteria, or the date of death from any cause in the absence of objectively determined disease progression or recurrence. |
| Phase 1: Disease Control Rate (DCR): Percentage of Participants With a Best Overall Response of CR, PR, and SD | Baseline through Measured Progressive Disease (Up to 11 Months) | DCR was defined as the percentage of participants who achieved a best overall response (BOR) of confirmed CR, confirmed PR, or SD out of all participants treatment. Best response is determined from a sequence of responses assessed. Two determinations of PR or better before progression, but not qualifying for a CR, are required for a best response of PR. CR is defined as the disappearance of all targeted and non-target lesions and no appearance of new lesions. PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions and no appearance of new lesions. |
| Phase 1: PFS | Baseline to Objective Progression or Death Due to Any Cause (Up to 11 Months) | PFS was defined as the time from study enrollment (for non-randomized cohorts)/ the time from randomization (for randomized cohorts) to the first observation of progressive disease (PD) overall response or death without documented disease progression per RECIST V1.1 criteria. |

Participant flow
Pre-assignment details
A participant was identified as having completed the study if the participant was observed until event of progressive disease (PD) or death, or the participant had discontinued study treatment and is in follow up at the time of the final analysis. The study was terminated due to an unexpected toxicity finding.
