A Study of Carboplatin and Paclitaxel With or Without MEDI-575 in Untreated, Advanced Non-Small Cell Lung Cancer

Phase 2TerminatedNCT01268059

MedImmune LLC99 enrolled

Overview

The purpose of this study is to evaluate the dose, antitumor activity, safety and pharmacology of MEDI-575 in combination with carboplatin/paclitaxel in subjects with previously untreated, advanced non-small cell lung cancer (NSCLC).

This is a Phase 1b/2, multicenter, open-label study of MEDI-575 to evaluate the dose, anti-tumor activity, safety, and pharmacology (pharmacokinetics, immunogenicity, and biomarkers) of MEDI-575 in combination with carboplatin/paclitaxel in subjects with previously untreated, advanced non-small cell lung cancer. This study has two phases: dose determination (Phase 1b) and randomization (Phase 2).

Interventions

CarboplatinDRUG

Carboplatin (carboplatin area under the plasma concentration-time curve \[AUC\] of 6 milligram per milliliter into minute \[mg/mL\*min\] administered as an intravenous (IV) infusion once every 21 days on Day 1, for a total of 6 doses (cycles) until unacceptable toxicity, disease progression, or other reasons for participant withdrawal.

PaclitaxelDRUG

Paclitaxel 200 milligram per square meter (mg/m\^2) administered as an intravenous (IV) infusion once every 21 days on Day 1, for a total of 6 doses (cycles) until unacceptable toxicity, disease progression, or other reasons for participant withdrawal.

MEDI-575DRUG

MEDI-575 at a dose of 25 milligram per kilogram (mg/kg) administered as an IV infusion once every 21 days on Day 1 for a total of 6 cycles until unacceptable toxicity, disease progression, initiation of alternative anticancer therapy, or other reasons for participant withdrawal. MEDI-575 alone continued in those participants who achieved stable disease or better at the completion of carboplatin/paclitaxel therapy and did not demonstrate toxicity to MEDI-575.

Outcomes

Primary Outcomes

Number of Participants With Dose Limiting Toxicities (DLT): Phase 1b

A DLT was defined as: 1. Any treatment-related Grade 3 or higher non-hematologic toxicity that occurred during the DLT assessment period with the following exceptions: 1. Grade 3 fever (in the absence of neutropenia) defined as more than (\>) 40.0 degree Celcius (\> 104.0 degree Fahrenheit) that resolved to normal or baseline within 24 hours of treatment and was not considered a serious adverse event (SAE); or 2. Grade 3 rigors/chills that responded to optimal therapy. 2. Any treatment-related Grade 3 or higher hematologic toxicity.

Time frame: From Day 1 to Day 21 of first cycle

Progression Free-Survival (PFS)

Progression-free survival defined as the time from randomization (randomization referred to the date of treatment assignment) to disease progression (defined according to Response Evaluation Criteria for Solid Tumors \[RECIST\] version 1.1 guidelines) or death due to any cause, whichever occurs first. Participants without progression or death at the time of analysis were censored at their last date of tumor evaluation. PFS was assessed only in North America/European Union (EU) participants. Progression-free survival was evaluated using Kaplan-Meier method.

Time frame: From randomization until the end of study (14 months from last participant enrolled or sponsor stopped the study), assessed at every 6 weeks until disease progression and every 3 months until the end of the study (approximately 3 years)

Secondary Outcomes

Best Overall Response

Best overall response of a participant was defined as the best tumor response \[Complete Response (CR), Partial Response (PR), Stable Disease (SD), or Progressive Disease (PD)\] observed during the trial period assessed according to the Response Evaluation Criteria for Solid Tumors (RECIST) version 1.1 criteria. The participant's best overall response assignment depended on the findings of both target and non-target disease and also on the appearance of new lesions. CR was defined as disappearance of tumor lesions, PR was defined as a decrease of at least 30 percent (%) in the sum of diameters of target lesion, SD was defined as steady state of disease, and PD was defined as an increase of at least 20% in the sum of diameters of target lesions.
