Inclusion criteria

* Confirmed diagnosis of advanced, refractory breast or prostate cancer that is evaluable by radiologic testing. Participants must have experienced tumor progression on or treatment intolerance to at least one prior therapy and have declined or are ineligible for a standard treatment. * For participants with metastatic castrate-resistant prostate cancer only: * Must continue ongoing androgen deprivation therapy with castrate levels of serum testosterone \<50 nanogram/deciliter (ng/dL) determined within 4 weeks prior to starting treatment * If receiving an antiandrogen as part of first-line hormonal therapy, must have shown progression of disease off the antiandrogen prior to enrollment * Must be willing to continue androgen deprivation therapy while on study, if no prior orchiectomy * Must meet at least 1 of the following 3 criteria for progressive metastatic disease, according to Prostate Cancer Working Group 2 (PCWG2) criteria: * A rise in prostate-specific antigen (minimal value 2 ng/milliliter (mL); ≥3 consecutive rising values) * ≥2 new metastases on transaxial imaging or radionuclide bone scan * Soft tissue progression * Replacement hormone therapy initiated before study entry is permitted * For participants with breast cancer only: * May continue ongoing antiestrogen therapy * Replacement hormone therapy initiated before study entry is permitted * May continue ongoing trastuzumab therapy * Have adequate organ and hematologic function, including: Hepatic: Bilirubin ≤1.5 × the upper limit of normal (ULN), and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 × ULN.

MeasureTime frameDescription
Percentage Change From Baseline in Peripheral Blood Immune Cell (PBIC) SubsetsBaseline to Day 8 after 1st doseThe immunomodulatory activity of the drug was documented by examining markers that include, but are not limited to: Live-Dead, Cluster of Differentiation 3 (CD3), CD4, CD8, CD14, CD16, Foxhead Box p3 (FoxP3), PD-1, Ki-67, Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4), Human Leukocyte Antigen-D-relate (HLA-DR), T-cell immunoglobulin and mucin-3 (TIM-3), lymphocyte-activation gene 3 (LAG-3), and Inducible T-cell COStimulator (ICOS). The expression of these markers was quantified by flow cytometric analysis with an antibody panel.
Percentage Change From Baseline in Serum CytokinesBaseline to Day 8 after 1st doseThe immunomodulatory activity of the drug was measured in participants with advanced, refractory breast or prostate cancers using serum cytokines. Serum cytokine levels was determined by MSD multiplex cytokine immunoassay technology or ELISA, and that may include but not be limited to Interleukin 6 (IL-6), IL-8, IL-10 and Tumor necrosis factor (TNF-α).
Serum Cytokine LevelsDay 8The immunomodulatory activity of the drug was measured in participants with advanced, refractory breast or prostate cancers using serum cytokines. Serum cytokines will be determined by MSD multiplex cytokine immunoassay or ELISA. The markers to be measured using these technologies include, but are not limited to: CSF-1, IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-34, and TNF-α.

Pharmacokinetics (PK): Area Under the Concentration Curve of LY30228550, 1, 4, 24, 48, 72 and 168 hours post dose on Day 1 and Day 29Area under the concentration versus time curve from time zero to tau (τ) of LY3022855 (AUC\[0- τ\]), where tau is dosing interval of (0-14 days).
Percentage of Participants With a Best Overall Disease Control Response (Disease Control Rate)Baseline up to 6 cycles (cycle = 6 weeks)Disease control rate is the percentage of participants with a confirmed CR, PR or SD, as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in sum of longest diameter of target lesions without new lesion and progression of non-target lesion; SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Disease control rate is calculated as a total number of participants with CR or PR or SD divided by the total number of participants treated, then multiplied by 100.

Percentage Change From Baseline in Serum Cytokines

The immunomodulatory activity of the drug was measured in participants with advanced, refractory breast or prostate cancers using serum cytokines. Serum cytokine levels was determined by MSD multiplex cytokine immunoassay technology or ELISA, and that may include but not be limited to Interleukin 6 (IL-6), IL-8, IL-10 and Tumor necrosis factor (TNF-α).

Time frame: Baseline to Day 8 after 1st dose

Population: All enrolled participants who received at least one dose of study drug and have baseline and post baseline data for Serum Cytokines.

Percentage of Participants With a Best Overall Disease Control Response (Disease Control Rate)

Disease control rate is the percentage of participants with a confirmed CR, PR or SD, as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in sum of longest diameter of target lesions without new lesion and progression of non-target lesion; SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Disease control rate is calculated as a total number of participants with CR or PR or SD divided by the total number of participants treated, then multiplied by 100.

Time frame: Baseline up to 6 cycles (cycle = 6 weeks)

Population: All enrolled participants who received at least one dose of study drug and have baseline and post-baseline data for disease control rate.
