Arm Intervention/treatment
Active Comparator: A: Docetaxel
Standard of care (SOC) docetaxel 75 mg/m² intravenously every 3 weeks and prednisone 5 mg orally twice daily continuously while receiving docetaxel therapy
Drug: docetaxel
Docetaxel 75 milligrams per square meter (mg/m²) intravenously on Day 1 of a 21-day cycle. Patients may receive up to 10 cycles of study therapy or until progressive disease. Additional cycles may be approved by sponsor as long as the patient is benefitting from therapy.

Drug: Prednisone
Prednisone 5 mg given orally twice daily continuously while receiving docetaxel therapy

Experimental: B: LY2181308 + Docetaxel
LY2181308 administered with docetaxel 75 mg/m² intravenously every 3 weeks and prednisone 5 mg orally twice daily continuously while receiving docetaxel
Drug: docetaxel
Docetaxel 75 milligrams per square meter (mg/m²) intravenously on Day 1 of a 21-day cycle. Patients may receive up to 10 cycles of study therapy or until progressive disease. Additional cycles may be approved by sponsor as long as the patient is benefitting from therapy.

Drug: LY2181308 sodium
LY2181308 sodium (referred to as LY2181308 throughout this record) administered weekly plus docetaxel 75 mg/m² intravenously administered every 21 days. Patients may receive up to 10 cycles of study therapy or until progressive disease. Additional cycles may be approved by sponsor as long as the patient is benefitting from therapy.

Drug: Prednisone
Prednisone 5 mg given orally twice daily continuously while receiving docetaxel therapy




Primary Outcome Measures :
  1. Progression-free Survival (PFS) in Participants With Hormone Refractory Prostate Cancer (HRPC) Administered LY2181308 Sodium Plus Docetaxel Compared to Docetaxel Alone [ Time Frame: Baseline to measured progressive disease or death due to any cause up to 44.68 months ]
    PFS is defined as the time from date of first dose to the first observation of progression of disease (PD) or death due to any cause. PD was determined using the Response Evaluation Criteria In Solid Tumors (RECIST) criteria. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion. For participants who had no PD or death, PFS was censored at their last contact. Participants were still followed for PFS after they stopped receiving study drug.

  2. Number of Participants With Adverse Events (Safety) [ Time Frame: First treatment dose up to 19 months ]
    Data are presented as number of participants who experienced serious adverse events or all other nonserious adverse events during the study including the 30-day follow-up period. A summary of serious adverse events and other nonserious adverse events is located in the Reported Adverse Event section. The participants received maximum 24 cycles of treatment (1cycle = 3 weeks). Safety data were collected up to 24 cycles plus 30 days of follow-up for a total up to 19 months.


Secondary Outcome Measures :
  1. Adverse Event Profile [ Time Frame: First treatment dose up to 19 months ]
    Data presented are the number of participants with all treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), discontinuations due to SAEs and AEs, and deaths that occurred in this study that were assessed by investigators as possibly related to study drug. The participants received maximum 24 cycles of treatment (1cycle = 3 weeks). Safety data were collected up to 24 cycles plus 30 days of follow-up for a total up to 19 months.

  2. Pharmacokinetics of Docetaxel: Area Under the Concentration Time Curve From Time Zero to Infinity (AUC0-infinity) [ Time Frame: Predose up to 8 hours postdose in Cycle 1 ]
  3. Prostate Specific Antigen (PSA) Kinetics: Percentage of Participants With PSA Response (Response Rate) [ Time Frame: Baseline, 18 months ]
    PSA response was defined as a post-baseline PSA level decline of at least 50% relative to the baseline value. Response rate calculated as 100*n/N where n=the number of participants with responses and N=the total number of participants treated.

  4. Estimate Overall Survival [ Time Frame: First treatment to death due to any cause up to 45.54 months ]
    Overall survival is defined as the time from date of first treatment to the date of death due to any cause. For participants who were alive, overall survival was censored at their last contact. Participants were still followed for overall survival after they stopped receiving study drug.

  5. Estimate Duration of Overall Response [ Time Frame: Time of response to time of measured progressive disease up to 41.00 months ]
    The duration of response [complete response (CR) or partial response (PR)] was defined as the time from first objective status assessment of CR or PR to the first time of progression or death as a result of any cause. CR or PR is classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. For participants who had no progression or death, the duration of response was censored at their last contact.

  6. Percentage of Participants With Complete Response or Partial Response (Overall Response Rate) [ Time Frame: Baseline to measured progressive disease up to 41.00 months ]
    Overall response rate was defined as the percentage of participants who achieved a complete response (CR) or partial response (PR) per the Response Evaluation Criteria In Solid Tumors (RECIST) criteria. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. Objective response rate is calculated as a total number of participants with CR or PR divided by the total number of participants treated multiplied by 100.

  7. Change From Baseline to Day 21 in Granulocyte Colony Stimulating Factor(G-CSF) (Assess Biomarker Responses) [ Time Frame: Baseline, 21 days ]
    G-CSF [international units per milliliter (IU/mL)] was used to estimate biomarker responses and is presented as the percentage change from baseline.

  8. Functional Assessment of Cancer Therapy-Prostate Cancer (FACT-P) Total Score at 3 Months (Participant Reported Outcomes) [ Time Frame: 3 months ]
    The FACT-P is a 39-item participant-rated questionnaire which assesses physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), functional well-being (7 items), and additional prostate cancer specific concerns (12 items). All items are scored from 0 (not at all) to 4 (very much). The total FACT-P score ranges from 0-156, with higher scores representing a better quality of life with fewer symptoms.

  9. Functional Assessment of Cancer Therapy-General (FACT-G) Total Score at 3 Months (Evaluate Clinical Symptoms) [ Time Frame: 3 months ]
    The total FACT-G is the sum of 4 subscale scores on the FACT-Prostate Cancer (FACT-P) participant-rated questionnaire representing general cancer symptoms: physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), and functional well-being (7 items). All items are scored from 0 (not at all) to 4 (very much). The total FACT-G score ranges from 0-108, with higher scores representing a better quality of life with fewer symptoms.


Other Outcome Measures:
  1. Number of Participants Who Died Due to Progressive Disease During the 30 Days Following Discontinuation From Study Treatment [ Time Frame: Study treatment discontinuation up to 30 days post study treatment discontinuation ]
