A Study of Olaratumab and Doxorubicin in Participants With Advanced Soft Tissue Sarcoma

An Open-Label Study to Evaluate the Pharmacokinetics of Doxorubicin Following the Concomitant Intravenous Administration of Olaratumab (IMC-3G3) to Patients With Advanced Soft Tissue Sarcoma

The purpose of this study is to assess how the body handles olaratumab when it is given with another drug called doxorubicin.

The safety and tolerability of these drugs will be studied. Each participant will complete two 21-day cycles in a fixed order. Participants who complete Cycle 2 may continue to receive olaratumab + doxorubicin for an additional six 21-day cycles and then may receive olaratumab alone until discontinuation criteria are met.

Screening is required within 21 days prior to first dose.

Part B was added in October, 2015 to assess how the body handles a higher dose of olaratumab when given with doxorubicin.

Participants may only enroll in one part.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Part A; Doxorubicin Alone: On Cycle 1, Day 1, participants received 75 milligram/square meter (mg/m2) of doxorubicin intravenously (IV). Olaratumab Alone: On Cycle 1, Day 10, participants received 15 milligram/kilogram (mg/kg) of olaratumab IV. Olaratumab + Doxorubicin: For Cycles 2 to 8, participants received 15 mg/kg of olaratumab on Days 1 and 8 of each 21-day cycle, IV and 75 mg/m2 of doxorubicin IV immediately following the completion of the olaratumab infusion. Participants continued to receive olaratumab monotherapy (on days 1 and 8 of each cycle) for Cycle 9 onward, until discontinuation criteria are met.	Drug: Olaratumab; Administered IV; Other Names: LY3012207; IMC-3G3; Drug: Doxorubicin; Administered IV
EXPERIMENTAL: Part B; Doxorubicin Alone: On Cycle 1, Day 1, participants received doxorubicin 75 mg/m2 IV Olaratumab Alone: On Cycle 1, Day 10, participants received 20 mg/kg of olaratumab IV. Olaratumab + Doxorubicin: For Cycle 2, participants received 20 mg of olaratumab on Days 1 and 8 of each 21-day cycle, IV. On Day 1 of Cycle 2, doxorubicin 75 mg/m2 was administered IV immediately following the completion of the olaratumab infusion. For Cycles 3 - 8, Day 1 and 8, olaratumab 15 mg/kg was administered and on Day 1 doxorubicin 75 mg/m2 was administered IV immediately following the completion of the olaratumab infusion. Participants continued to receive olaratumab monotherapy (on days 1 and 8 of each cycle) for Cycle 9 onwards, until discontinuation criteria are met.

Percentage of Participants With Olaratumab Antibodies	The formation of anti-drug antibodies (ADA) was assessed using validated ELISAs, following a 4-tier approach. Both the ADA screening assay and the neutralizing antibody assay were validated in accordance with the US Food and Drug Administration (FDA) Guidance for Industry. Participants who had positive samples for treatment emergence due to being <4-fold difference from baseline or occurred prior to drug exposure are reported.	Preinfusion on Day 1 of Cycles 1 through 3 and Preinfusion on Day 1 of Every Second Cycle Thereafter, Up to 30-Day Follow Up
Percentage of Participants With a Best Overall Response of Complete Response (CR) or Partial Response (PR) [Objective Response Rate (ORR)]	The percentage of participants with a best overall response achieving CR or PR (ORR) was defined using Response Evaluation Criteria In Solid Tumors (RECIST, version 1.1) criteria. Complete Response (CR) was defined as the disappearance of all target and non-target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 millimeter (mm) and normalization of tumor marker level of non-target lesions; Partial Response (PR) was defined as having at least a 30% decrease in sum of longest diameter of target lesions. The methodology for the confidence interval calculation is the "exact F" method.	Baseline to Measured Progressive Disease, Study Discontinuation or Death (Up to 24 Months)
