Inclusion Criteria
-
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.
-
Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) scale.
-
Have an estimated life expectancy of ≥12 weeks, in the judgment of the investigator.
-
Have submitted a tumor tissue sample, as follows:
- For participants entering the Phase 1a dose escalation: have submitted, if available, the most recent archival tumor tissue sample.
- For those participating ONLY in Phase 1b expansions: Have submitted tumor tissue sample from a newly obtained core or excisional biopsy for a tumor lesion (preferred) or a recent biopsy taken with 3 months prior to study enrollment and following the participants most recent prior systemic treatment and be willing to undergo a biopsy procedure during the study treatment period for collection of additional tumor tissue sample.
Exclusion Criteria
- 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.
