Primary Outcome Measures :
  1. Objective Response Rate [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Objective response is defined as a participant with the best overall response of complete response (CR) or partial response (PR), per Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1, prior to receiving any subsequent anticancer therapy and retreatment, and is confirmed by a consecutive response assessment at least 4 weeks (28 days) from the initial determination of CR/PR. Analyzed based on response assessments from both the Independent Review Committee (IRC) and investigators.

    CR: disappearance of all target lesions.Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.


  2. Overall Survival [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]
    Overall survival is defined as the time from the first dose date to death for any reason. Participants who were alive at the clinical data cut-off were censored at the last known alive date. Based on Kaplan-Meier estimates.


Secondary Outcome Measures :
  1. Overall Response Rate [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Overall response rate is defined as the percentage of participants with a response of CR or PR, regardless of confirmation, per RECIST v 1.1 prior to receiving any subsequent anticancer therapy and retreatment. Any participants not exhibiting a response (CR or PR) as defined above were considered non-responders. Analyzed based on response assessments from both the IRC and investigators.

    CR: disappearance of all target lesions.Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.


  2. Duration of Objective Response [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Duration of objective response is defined as the time from the date of first documented CR or PR of participants with a confirmed response to the documented date of progressive disease (PD) or death, whichever occurred first. Participants who neither progressed nor died are censored at the last evaluable disease assessment. Analyzed based on response assessments from both the IRC and investigators. Based on Kaplan-Meier estimates.

    CR: disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (includes the baseline sum). The sum must also demonstrate an absolute increase of at least 5 mm. (The appearance of one or more new lesions is also considered progression.)


  3. Progression-Free Survival [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Progression-free survival is defined as the time from the first dose date to the documented date of PD or death, whichever occurred first. Participants who neither progressed nor died were censored at the last evaluable disease assessment. Analyzed based on response assessments from both the IRC and investigators. Based on Kaplan-Meier estimates.

    PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (includes the baseline sum). The sum must also demonstrate an absolute increase of at least 5 mm. (The appearance of one or more new lesions is also considered progression.)


  4. Clinical Benefit Rate [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Clinical benefit rate is defined as the proportion of participants with an overall response of CR or PR or stable disease (SD) with SD of a minimum duration of 42 days from the first dose date. Analyzed based on response assessments from both the IRC and investigators.

    CR: disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

    PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (includes the baseline sum). The sum must also demonstrate an absolute increase of at least 5 mm. (The appearance of one or more new lesions is also considered progression.)


  5. Duration of Clinical Benefit [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]

    Duration of clinical benefit is defined as time from the date of first documented CR or PR or SD of ≥ 42 days from first dose date (-7 days to allow for scheduled visit window per the protocol) to the documented date PD or death, whichever occurs first. Analyzed based on response assessments from both the IRC and investigators.

    CR: disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.


  6. Rovalpituzumab Tesirine Antibody-Drug Conjugate Plasma Concentrations by Study Visit [ Time Frame: Cycle 1: Day 1, 30 minutes pre-infusion; Day 1, 30 minutes post-infusion; Day 3; Day 15; Day 29. Cycle 2: Day 1, 30 minutes pre-infusion; Day 1, 30 minutes post-infusion; Day 3; Day 15; Day 29; End of Treatment (up to Day 29). ]
  7. Number of Anti-Therapeutic Antibody (ATA) Positive Participants [ Time Frame: up to 122.4 weeks; mean (SD) duration of follow-up was 29.0 (23.77) weeks ]
  8. Number of Participants With Treatment-Related Adverse Events (TEAEs) During Initial Treatment [ Time Frame: From first dose of study drug through the end of the initial treatment period (84 ± 6 days) ]
    An adverse event (AE) is defined as any untoward medical occurrence which does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is any untoward medical occurrence that at any dose: is fatal or life-threatening; results in death or hospitalization; is disabling/incapacitating or a congenital anomaly/birth defect; is medically significant. AE severity was graded using the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.03 terminology: grade 1=mild; grade 2=moderate; grade 3=severe; grade 4 life-threatening; grade 5=death. TEAEs were defined as AEs that were newly occurring or worsened following study treatment.

  9. Number of Participants With TEAEs Occurring in at Least 10% of All Participants During Initial Treatment [ Time Frame: From first dose of study drug through the end of the initial treatment period (84 ± 6 days) ]
    TEAEs were defined as AEs that were newly occurring or worsened following study treatment.
