What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-Free Survival (PFS)

    PFS is measured from randomization to the earliest date of the following events: PD according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria version (v) 1.1, 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, unequivocal evidence of progression by bone scan, clinical progression or death from any cause. For participants who had no documented PD or death or had started new anti-cancer therapy or were lost to follow-up, PFS was censored at their last tumor assessment.

    Measured: Randomization to Measured PD or Death Due to Any Cause Up to 23 Months

Secondary outcomes (10)
  1. Overall Survival (OS)

    OS was defined as the time from the date of randomization to the date of death from any cause. If the participants were alive at the end of the follow-up period or were lost to follow-up, OS time was censored on the last date the participant was known to be alive.

    Measured: Randomization to Death Due to Any Cause Up to 36 Months

  2. Percentage of Participants Who Achieved a Best Overall Response of Complete Response (CR) or Partial Response (PR) [Objective Response Rate (ORR)]

    Best response is categorized using the RECIST v1.1 guidelines. CR is the disappearance of all non-nodal target lesions, with the short axes of any target lymph nodes reduced to <10 mm. PR is a ≥30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph nodes), taking as reference the pretreatment sum diameter. Percentage of participants = (number of participants who had CR or PR) / (number of participants treated) * 100.

    Measured: Randomization to Objective PD or Death Up to 23 Months

  3. Percentage of Participants With a ≥50% Decrease in Prostate Specific Androgen (PSA) From Pretreatment to Any Time

    Decrease in PSA ≥50% from pretreatment required confirmation no less than 3 weeks after the initial suggestion of response and occurring prior to documentation of PD. Percentage of participants = (number of participants who had ≥50% decrease in PSA at any time) / (number of participants treated) * 100.

    Measured: Pretreatment to PD Up to 23 Months

  4. Percentage of Participants With a ≥30% Decrease in PSA From Pretreatment to Week 12

    Percentage of participants = (number of participants who had ≥30% decrease in PSA at Week 12) / (number of participants treated) * 100.

    Measured: Pretreatment through Week 12

  5. Summary Listing of Participants Reporting Treatment-Emergent Adverse Events (TEAE)

    Data presented are the number of participants who experienced serious adverse events (SAEs) and other nonserious adverse events (AEs). For participants in mitoxantrone group who had PD and chose optional IMC-3G3 follow-on treatment, the baseline was defined as the last assessment prior to the start of the olaratumab treatment. A summary of SAEs and other nonserious AEs, regardless of causality, is located in the Reported Adverse Events section.

    Measured: From Start of Treatment Through Study Completion Up to 36 months

  6. PFS Based on Baseline Circulating Tumor Cells (CTC) Counts

    High expression (HE) of CTC was defined as having CTC counts ≥5 cells/7.5 milliliter (mL) and low expression (LE) of CTC was defined as having CTC counts <5 cells/7.5 mL. PFS is measured from randomization to the earliest date of the following events: PD according to RECIST criteria v. 1.1, is a ≥20% increase in the sum diameter of the target lesions taking as reference the smallest sum on study and an absolute increase in the sum diameter of ≥5 mm, the appearance of 1 or more new lesions and/or unequivocal progression of existing nontarget lesions, unequivocal evidence of progression by bone scan, clinical progression or death from any cause.

    Measured: Randomization to Measured PD or Death Due to Any Cause Up to 23 Months

  7. OS Based on Baseline CTC Counts

    HE of CTC was defined as having CTC counts ≥5 cells/7.5 mL and LE of CTC was defined as having CTC counts <5 cells/7.5 mL. OS was defined as the time from the date of randomization to the date of death from any cause.

    Measured: Randomization to Death Due to Any Cause Up to 36 Months

  8. Number of Participants With Negative Platelet-Derived Growth Factor Receptor Alpha (PDGFRα) Protein Expression by Immunohistochemistry (IHC)

    PDGFRα protein expression (pretreatment) by IHC was assessed in tumor cells, and was provided as a dichotomous variable with "positive" and "negative" expression. "Positive" corresponds to weak intensity membranous staining comprising greater than 30% of the tumor and/or moderate to strong intensity membranous staining comprising greater than 5% of the tumor. "Negative" corresponds to staining that does not meet these requirements.

    Measured: Baseline

  9. Percentage of Participants With Anti-Olaratumab Antibody Assessment (Immunogenicity)

    Participants with Treatment Emergent (TE) anti-olaratumab antibodies were participants with a 4-fold increase (2 dilutions) increase over a positive baseline antibody titer or for a negative baseline titer, a participant with an increase from the baseline to a level of 1:20.

    Measured: From Start of Treatment up to 9 Months

  10. Maximum Concentration (Cmax) of Olaratumab Cycles 1, 2 and 3

    Measured: Day 1 of Cycles 1, 2 and 3, and Day 8 of Cycles 1 and 3 (21-day cycle)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Olaratumab, Mitoxantrone and Prednisone in people with Prostate Cancer, run by Eli Lilly and Company at 40 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in Germany, Hungary, Spain, Italy, Poland and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-Free Survival (PFS) (time frame: Randomization to Measured PD or Death Due to Any Cause Up to 23 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Sep 2019.
