E7050 in Combination With Cetuximab Versus Cetuximab Alone in the Treatment of Platinum-Resistant Squamous Cell Carcinoma of the Head and Neck

Eisai Inc.95 enrolled

Overview

The purpose of this study is to determine whether participants with platinum-resistant squamous cell carcinoma of the head and neck (SCCHN) who receive either E7050 administered with cetuximab or cetuximab alone experience greater benefit.

This open-label, multicenter, randomized study will consist of a Phase 1b: a safety run-in period with 3 ascending doses of E7050 in combination with cetuximab; and a Phase 2 portion: a randomized 2-arm period. Approximately 95 participants with platinum-resistant squamous cell carcinoma of the head and neck will be enrolled in the study (10-15 participants in the Phase 1b portion and 80 participants in the Phase 2 portion). Participants will only participate in either the Phase 1b or the Phase 2 portion of the study. In the Phase 2 portion, participants will receive study treatment (E7050 plus cetuximab or cetuximab alone) for approximately six 28-day cycles (24 weeks). Beyond 24 weeks, participants who are experiencing clinical benefit may continue E7050 plus cetuximab, cetuximab alone or E7050 alone (Arm 1), or may continue cetuximab alone (Arm 2), depending on the original randomization treatment arm, for as long as clinical benefit is sustained and the treatment is well tolerated.

Outcomes

Primary Outcomes

Phase 1b: Number of Participants With Dose-limiting Toxicities (DLTs) as Per National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (NCI CTCAE v4.0)

DLT:adverse events graded as NCI CTCAEv4.0 occurring less than or equal to(\<=)28 days after treatment.Events as: Non-hematological: 1)Grade greater than or equal to(\>=)3 peripheral neuropathy; 2)Grade 3 fatigue or 2 point decline in eastern cooperative oncology group performance status that persisted for greater than(\>)7 days; 3)Grade \>=3 nausea,vomiting despite optimal antiemetic treatment; 4)Any nonhematologic toxicity of Grade \>=3, with exceptions as alopecia,single laboratory values out of normal range,hypersensitivity reaction. Hematological 1)Grade 4 neutropenia lasting \>7 days; 2)Febrile neutropenia as fever \>=38.5 degree celsius with absolute neutrophil count less than(\<)1.0\*10\^9 per liter(/L); 3)Grade 3 thrombocytopenia with nontraumatic bleeding requiring platelet transfusion; 4)Grade 4 thrombocytopenia with/without nontraumatic bleeding. Other 1)Study drug related death; 2)Toxicity that dose escalation committee believed to be DLT that was not covered by above DLT criteria.

Time frame: Cycle 1 (Cycle length is equal to [=] 28 days)

Phase 1b: Plasma Concentration of Golvatinib When Given in Combination With Cetuximab

Time frame: Cycle 1: 0-48 hours post-dose (Each cycle=28 days)

Phase 2: Number of Participants With Grade 3 or Higher Treatment-emergent Adverse Events (TEAEs)

TEAEs are defined as an adverse event that has an onset date, or a worsening in severity from baseline (pre-golvatinib), on or after the first dose of golvatinib. The severity was graded according to CTCAE v4.0. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to adverse event.

Time frame: Up to 5 years 11 months

Secondary Outcomes

Phase 2: Progression-free Survival (PFS)

PFS is defined as the time from the date of randomization until the earlier of the following two events: the date of PD or the date of death based on response evaluation criteria in solid tumor (RECIST) v1.1. PD is defined as at least a 20 percent (%) increase or 5 millimeter (mm) increase in the sum of diameters of target lesions (taking as reference the smallest sum on study) recorded since the treatment started or the appearance of 1 or more new lesions. PFS was estimated and analyzed using Kaplan Meier method. As planned, data for this endpoint was analyzed and collected till primary completion date.

Time frame: From the date of randomization until the earlier of the following two events: the date of PD or the date of death (Up to approximately 4 years 4 months)

Phase 2: Percentage of Participants With PFS at Week 12

PFS rate at week 12 is defined as the percentage of participants who were still alive without disease progression at 12 weeks from the date of randomization. PFS is defined as the time from the date of randomization until the earlier of the following two events: the date of PD or the date of death based on RECIST v1.1. PD is defined as at least a 20% increase or 5 mm increase in the sum of diameters of target lesions (taking as reference the smallest sum on study) recorded since the treatment started or the appearance of 1 or more new lesions. PFS rate was estimated and analyzed using Kaplan Meier method.

Time frame: At Week 12

Phase 2: Time to Progression (TTP)

TTP is defined as the time from the date of randomization until the date of PD based on RECIST v1.1. PD is defined as at least a 20% increase or 5 mm increase in the sum of diameters of target lesions (taking as reference the smallest sum on study) recorded since the treatment started or the appearance of 1 or more new lesions. TTP was estimated and analyzed using Kaplan Meier method. As planned, data for this endpoint was analyzed and collected till primary completion date.

Time frame: From the date of randomization until the date of PD (Up to approximately 4 years 4 months)

Phase 2: Overall Survival (OS)

OS is defined as the time from the date of randomization until the date of death. OS was analyzed using Kaplan Meier method. As planned, data for this endpoint was analyzed and collected till primary completion date.

Time frame: From the date of randomization until the date of death (Up to approximately 4 years 4 months)

Phase 2: Percentage of Participants With Overall Response

Overall response rate is defined as percentage of participants with complete response (CR) or partial response (PR) based on RECIST v1.1. CR is defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to \<10 mm. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. As planned, data for this endpoint was analyzed and collected till primary completion date.

Time frame: From the date of randomization until CR or PR (Up to approximately 4 years 4 months)
