You may qualify if…

Histologic or cytologic confirmation of advanced solid tumor.
For LY3300054 + abemaciclib only: No participants with liver metastases. Participants must have normal aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, direct bilirubin.
For LY3300054 + abemaciclib in HR+, HER- breast cancer:
Express at least 1 of the hormone receptors [HR; estrogen receptor (ER) or progesterone receptor (PR)] by immunohistochemistry (IHC) to fulfill the requirement for HR+ disease on the primary tumor or metastatic lesion of the breast cancer. ER and PR assays are considered positive if there is at least 1% positive tumor nuclei in their sample as defined in the relevant American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) or local guidelines.
To fulfill the requirement of HER2- disease, a breast cancer must not demonstrate, at initial diagnosis or upon subsequent biopsy, overexpression of HER2 by either IHC or in-situ hybridization (ISH) as defined in the relevant ASCO/CAP or local guidelines.
Most recent HR and HER2 receptor testing should be used to determine eligibility.
Have previously received prior treatment with at least 1 but no more than 3 chemotherapy regimens in the metastatic setting.
Have AST, ALT, GGT, and AP that are ≤2.5x upper limit of normal (ULN) and normal bilirubin (total and direct) regardless of liver involvement.
For LY3300054 + merestinib in pancreatic cancer:
Histologically or cytological confirmed diagnosis of metastatic or locally advanced, unresectable pancreatic adenocarcinoma (excluding other pancreatic malignancies for example, acinar cell carcinomas, adenosquamous carcinomas, and neuroendocrine islet cell neoplasms).
Have had disease progression, be refractory or intolerant to no more than 2 prior systemic regimens.
For LY3300054 + LY3321367 in PD-1/PD-L1-naive, MSI-H/MMR-deficient advanced solid tumors:
Have histologically or cytologically confirmed diagnosis of advanced solid tumor AND shown to be MSI-H or MMR-deficient.
For LY3300054 + LY3321367 in PD-1/PD-L1- resistant/refractory, MSI-H/MMR-deficient advanced solid tumors:
Have histologically or cytologically confirmed diagnosis of advanced solid tumor AND shown to be MSI-H or MMR-deficient.
Prior exposure to PD-1/PD-L1 agent regardless of response.
For Phase 1b LY3300054 monotherapy or combination therapy, no prior treatment with a PD-1 or PD-L1 agent is allowed.
Exception: the LY3321367 combination in participants with PD-1/PD-L1- resistant/refractory, MSI-H, where prior exposure to PD-1/PD-L1 agent required.
For Phase 1a LY3300054 monotherapy or combination therapy, previous immunotherapy is acceptable if the following criteria are met:
Must not have experienced a toxicity that led to permanent discontinuation of prior immunotherapy.
Must have completely recovered or recovered to baseline prior to screening from any prior adverse events (AEs) occurring while receiving prior immunotherapy.
Must not have experienced a Grade ≥3 immune-related AE or an immune-related neurologic or ocular AE of any grade while receiving prior immunotherapy.
Must not have required the use of additional immunosuppressive agents other than corticosteroids for the management of an AE, not have experienced recurrence of an AE if re-challenged, and not currently require maintenance doses of >10 milligrams prednisone or equivalent per day.
Have at least 1 measurable lesion assessable using standard techniques by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
Have adequate organ function.

You may not qualify if…

Have a serious concomitant systemic disorder including human immunodeficiency virus (HIV), active hepatitis B virus (HBV), active hepatitis C virus (HCV), active autoimmune disorder or disease requiring high dose of steroids.
Have a bowel obstruction, history or presence of inflammatory enteropathy or extensive intestinal resection or chronic diarrhea.
Have evidence of interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity or active, noninfectious pneumonitis.
Have an active infection requiring systemic therapy.
Have moderate or severe cardiovascular disease.
Have symptomatic or uncontrolled brain metastases, spinal cord compression, or leptomeningeal disease requiring concurrent treatment.
Have received a live vaccine within 30 days before the first dose of study treatment.
Have a significant bleeding disorder or vasculitis or had a Grade ≥3 bleeding episode within 12 weeks prior to enrollment.
