About

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.

Enrollment: 49 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

49 participants in 2 patient groups

Part A

Experimental group

Description:

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.

Treatment:

Drug: Olaratumab

Drug: Doxorubicin

Part B

Experimental group

Description:

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.

Treatment:

Drug: Olaratumab

Drug: Doxorubicin
