A Study in Advanced Cancer

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to find a recommended dose level and schedule of dosing LY2940680 that can safely be taken by participants with advanced cancer. The study will also explore the changes in a cancer marker level in skin, hair follicles, buccal cells, and tumor cells. Finally, the study will help document any antitumor activity this drug may have.

Detailed Description
-----------------
Participants may include those who have previously received treatment with another hedgehog smoothened (Hh/Smo) inhibitor (excluding LY2940680).

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Have histological or cytological evidence of a diagnosis of cancer that is advanced and/or metastatic. The patient must be, in the judgment of the investigator, an appropriate candidate for experimental therapy. Have the presence of measurable or nonmeasurable disease Have adequate organ function, including: Hematologic: Absolute neutrophil count (ANC) greater than or equal to 1.5 x 109/L, platelets greater than or equal to 100 x 109/L, and hemoglobin greater than or equal to 9 g/dL. Patients may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator. Initial treatment must not begin until 5 days after the erythrocyte transfusion. Hepatic: Bilirubin less than or equal to 1.5 times upper limits of normal (ULN), ALT, and aspartate transferase (AST) less than or equal to 2.0 times ULN. If the liver has tumor involvement AST and ALT equaling less than or equal to 5 times ULN are acceptable. Renal: Serum creatinine less than or equal to 1.5 times ULN. Have a performance status of less than or equal to 1 on the Eastern Cooperative Oncology Group (ECOG) scale Have discontinued previous treatments for cancer and recovered from the acute effects of therapy (for example, at least 42 days for mitomycin-C or nitrosoureas, 28 days for other chemotherapy and biologics. At the discretion of the investigator, hormone refractory prostate cancer patients who are stable on gonadotropin-releasing hormone (GnRH) agonist therapy and breast cancer patients who are stable on antiestrogen therapy (for example, an aromatase inhibitor) may continue treatment Exclusion Criteria: Have received treatment within 21 days of the initial dose of study drug with an experimental agent for noncancer indications that has not received regulatory approval for any indication. Have serious preexisting medical conditions Have symptomatic central nervous system (CNS) malignancy (with the exception of medulloblastoma) or metastasis (screening not required). Patients with treated CNS metastases are eligible for this study if they are not currently receiving corticosteroids and/or anticonvulsants, and their disease is asymptomatic and radiographically stable for at least 60 days. Have known current hematologic malignancies or acute or chronic leukemia Have a known active fungal, bacterial, and/or known viral infection including human immunodeficiency (HIV) or viral (A, B, or C) hepatitis (screening is not required) Have a second primary malignancy that in the judgment of the investigator and sponsor may affect the interpretation of results Have QTc interval of >500 msec on screening electrocardiogram Patients who have previously received treatment with LY2940680

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recommended Phase 2 Dose: Maximum Tolerated Dose | Recommended Phase 2 dose was determined by maximum tolerated dose (MTD), which was determined by Dose-limiting toxicity (DLT). For the purpose of this study, the MTD was defined as the highest tested dose that had <33% probability of causing a DLT in Cycle 1 of Part A. | Time to First Dose to the End of Cycle 1 of Part A (Up To 28 Days) | 

Secondary Outcome Measures

| Number of Participants With Clinical Benefit Rate (Stable Disease [SD] + Partial Response [PR] + Complete Response [CR]) | Clinical Benefit Rate is complete response (CR) + partial response (PR) + stable disease (SD) as classified by the investigator according to the Response Evaluation Criteria In Solid Tumors (RECIST version 1.1) guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is a ≥20% increase in the sum of diameter of the target lesions taking as reference the smallest sum on study and an absolute increase in the sum diameter of ≥5 millimeter (mm), the appearance of 1 or more new lesions and/or unequivocal progression of existing nontarget lesions. | Baseline to Disease Progression or Death Due to Any Cause (Up To 32 Months) | 
| Part C and D: Progression Free Survival (PFS) | For each participant in Part C and D who is not known to have died or to have had a progression of disease as of the data inclusion cut-off date, PFS was censored at the date of last objective progression-free disease assessment prior to the date of any subsequent systemic anticancer therapy. Progressive disease (PD) was determined using Response Evaluation Criteria In Solid Tumors (RECIST 1.1) criteria. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion. | Baseline to Progressive Disease or Death from Any Cause (Up To 32 Months) |
