A Study of Rovalpituzumab Tesirine as Maintenance Therapy Following First- Line Platinum-Based Chemotherapy in Participants With Extensive Stage Small Cell Lung Cancer (MERU)

Status: Active


This is a Phase 3, randomized, double-blind, placebo-controlled, multinational, and multicenter study to evaluate the efficacy of rovalpituzumab tesirine as maintenance therapy following first-line platinum-based chemotherapy.

Eligibility Criteria

Inclusion Criteria

  • Histologically or cytologically confirmed extensive-stage disease small cell lung cancer (ED SCLC) at initial diagnosis with ongoing clinical benefit (stable disease [SD], partial response [PR], or complete response [CR]) following completion of 4 cycles of first-line platinum-based therapy
  • Participant is eligible to be randomized at least 3 but no more than 9 weeks from Day 1 of the fourth cycle of first-line platinum-based chemotherapy.
  • Participants with a history of central nervous system (CNS) metastases prior to the initiation of first-line platinum-based chemotherapy must have received definitive local treatment and have documentation of stable or improved CNS disease status
  • Eastern Cooperative Oncology Group (ECOG) performance score of 0 or 1
  • Participants must have adequate bone marrow, renal and hepatic function
  • Availability of archived or representative tumor material for assessment of DLL3 expression

Exclusion Criteria

  • Any prior systemic chemotherapy, small molecule inhibitors, immune checkpoint inhibitors, other monoclonal antibodies, antibody-drug conjugates, radioimmunoconjugates, T-cell or other cell-based or biologic therapies, or any other anti-cancer therapy than that described in inclusion criteria for SCLC.
  • Any disease-directed radiotherapy (except prophylactic cranial irradiation, palliative radiotherapy to a radiographically documented non-progressing lesion for symptom control, or pre-planned radiotherapy for CNS metastases present prior to start of first-line therapy and non-progressing) after last dose of first-line chemotherapy.
  • Prior exposure to a pyrrolobenzodiazepine (PBD-based) or indolinobenzodiazepine-based drug, prior participation in a rovalpituzumab tesirine clinical trial, or known hypersensitivity or other contraindications to rovalpituzumab tesirine or excipient contained in the drug formulation.
