Outcome Measures
Primary Outcomes (1)
Number of Participants With Dose Limiting Toxicities (DLTs)
A DLT is defined as an adverse event that is likely related to the study medication or combination, and fulfils any one of the following criteria, graded according to the NCI-CTCAE (National Cancer Institute-Common Terminology Criteria for Adverse Events) version 5.0: * Grade 3 thrombocytopenia associated with clinically significant bleeding and requiring platelet transfusion or Grade 4 thrombocytopenia of any duration. * Grade ≥3 febrile neutropenia * Grade ≥3 anemia requiring a blood transfusion * Other Grade ≥4 toxicities, excluding few nonhematologic Toxicities * Any other significant toxicity deemed by the investigatory to be dose-limiting, such as: any toxicity that is possibly related to the study medication that requires the withdrawal of the participant from the study during 28-day DLT observation period), persistent Grade \>2 toxicities causing a delay of LY3475070 study treatment \>14 days during the 28-day DLT observation period.
Up to 28 days from the first dose
Secondary Outcomes (6)
Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve From Time Zero to Eight Hours (AUC[0-8]) of LY3475070
Cycle 1 Day 1 (Pre-dose, 0.5, 1, 2, 4, 6, 8 hours post-dose)
PK: Area Under the Concentration Versus Time Curve During 1 Dosing Interval (AUCtau) of LY3475070
Cycle 2 Day 1 (Pre-dose, 0.5, 1, 2, 4, 6, 8, 24 hours post-dose for the QD arms, Pre-dose, 0.5, 1, 2, 4, 6, 8 hours post-dose for the BID arms)
PK: Maximum Concentration (Cmax) of LY3475070
Day 1 of Cycles 1 and 2 (Pre-dose, 0.5, 1, 2, 4, 6, 8, 24 hours post-dose for the QD arms; Pre-dose, 0.5, 1, 2, 4, 6, 8 hours post-dose for the BID arms)
Overall Response Rate (ORR): Percentage of Participants With Complete Response (CR) or Partial Response (PR)
Baseline through Disease Progression or Death (Estimated at up to 10.4 Months)
Disease Control Rate (DCR): Percentage of Participants With a Best Overall Response of CR, PR, and Stable Disease (SD)
Baseline through Measured Progressive Disease (Estimated at up to 10.4 Months)

Study Arms (7)
Phase 1a Cohort A LY3475070 (dose escalation)
EXPERIMENTALParticipants received 150 milligram (mg) once daily or 300 mg once daily or 300mg twice daily or 600mg once daily oral LY3475070 on a 21-day cycle until progressive disease, unacceptable toxicity or other criterion for study discontinuation is met.
Phase 1a Cohort B LY3475070 + Pembrolizumab (dose escalation)
EXPERIMENTALParticipants received 150 mg once daily or 150 mg twice daily or 300 mg once daily or 300mg twice daily oral LY3475070 on a 21-day cycle in combination with an intravenous infusion of 200mg pembrolizumab on day 1 until progressive disease, unacceptable toxicity or other criterion for study discontinuation is met.

Phase 1b Cohort D1 LY3475070 + Pembrolizumab (dose expansion)
EXPERIMENTALLY3475070 administered orally and pembrolizumab administered IV. Based on Sponsor decision, Phase 1b expansion cohorts were not initiated.
Phase 1b Cohort D2 LY3475070 (dose expansion)
EXPERIMENTALLY3475070 administered orally. Based on Sponsor decision, Phase 1b expansion cohorts were not initiated.
Phase 1b Cohort E LY3475070 + Pembrolizumab (dose expansion)
EXPERIMENTALLY3475070 administered orally and pembrolizumab administered IV. Based on Sponsor decision, Phase 1b expansion cohorts were not initiated.

Eligibility Criteria
You may qualify if:
- Participants must have certain types of cancer such as breast cancer, pancreatic cancer, lung cancer, kidney cancer, skin cancer (melanoma), prostate cancer, and ovarian cancer
- Participants must have stopped other forms of treatment for the cancer
- In the expansion cohorts participants must be able and willing to provide a sample of the tumor before beginning treatment and a sample during the treatment. For certain tumor types, the result of a test on the tumor sample may exclude the participant from the study
