Study Evaluating the Safety of Rovalpituzumab Tesirine for Third-Line and Later Treatment of Subjects With Relapsed or Refractory Small Cell Lung Cancer

Phase 3

Withdrawn

• Conditions: Small Cell Lung Cancer
• Interventions: Drug: Dexamethasone; Drug: Rovalpituzumab tesirine

• Registration Number: NCT03334487
• Lead Sponsor: AbbVie

Brief Summary

A single-arm, open-label study to assess the overall safety of rovalpituzumab tesirine in participants with relapsed or refractory delta-like protein 3 (DLL3) expressing small cell lung cancer by evaluating the frequency of high grade (\>= Grade 3) select treatment-emergent adverse events (TEAEs).

Arm && Interventions

Group	Intervention	Description
Rovalpituzumab tesirine + dexamethasone	Dexamethasone	Rovalpituzumab tesirine 0.3 mg/kg administered intravenously on Day 1 of each 6-week cycle plus oral dexamethasone 8 mg twice daily on Day -1, Day 1, and Day 2 of 6-week each cycle.
Rovalpituzumab tesirine + dexamethasone	Rovalpituzumab tesirine	Rovalpituzumab tesirine 0.3 mg/kg administered intravenously on Day 1 of each 6-week cycle plus oral dexamethasone 8 mg twice daily on Day -1, Day 1, and Day 2 of 6-week each cycle.

Primary Outcome Measures

Name	Time	Method
Number of Participants with a High Grade (>= Grade 3) Protocol Specified TEAE	Approximately 32 months	Number of participants with a high grade (≥ Grade 3) protocol specified Treatment-Emergent Adverse Events (TEAEs) during and after treatment with rovalpituzumab tesirine. Severity of TEAEs will be graded at each study visit according to the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) version 4.03.

Secondary Outcome Measures

Name	Time	Method
Change in Participant Reported Outcome EORTC QLQC15-PAL	Approximately 32 months	The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Palliative Cancer (EORTC QLQ-C15-PAL) is a 15-item self-report questionnaire composed of 4 multi-item scales (physical \& emotional functioning, fatigue and pain) along with 6 individual items (nausea \& vomiting, dyspnea, insomnia, appetite loss, constipation, and global quality of life).
Progression Free Survival (PFS)	Approximately 32 months	PFS is based on independent review of radiographic assessment, defined as the time from randomization to documented disease progression or death from any cause, whichever occurs earlier.
Change in EORTC QLQ-LC-13	Approximately 32 months	The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Lung Cancer (EORTC QLQ-LC 13) is a lung cancer specific module developed to assess lung cancer-associated symptoms and treatment-related side effects among lung cancer patients.
Clinical Benefit Rate (CBR)	Approximately 32 months	CBR is defined as the proportion of participants with an objective response or stable disease (CR+PR+SD) according to RECIST version 1.1.
Objective response rate (ORR)	Approximately 32 months	ORR is defined as the percentage of participants whose best overall response is either complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Duration of Objective Response (DOR)	Approximately 32 months	DOR is defined as the time between the date of first response (CR or PR, whichever is recorded first) to the date of the first documented tumor progression (per RECIST version 1.1) or death due to any cause, whichever comes first.
Overall Survival (OS)	Approximately 32 months	Overall Survival (OS) is defined as the time from the date of randomization to the date of death from any cause.
