Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression-free Survival Per Independent Review Facility (IRF) [ Time Frame: Up to 60 months ]
    The time from the date of randomization to the date of first documentation of progressive disease (PD), death due to any cause, or receipt of subsequent anticancer chemotherapy to treat residual or progressive disease whichever occurred first.


Secondary Outcome Measures :
  1. Progression-free Survival Per IRF in Patients With Systemic Anaplastic Large Cell Lymphoma (sALCL) [ Time Frame: Up to 60 months ]
    The time from the date of randomization to the date of first documentation of progressive disease (PD), death due to any cause, or receipt of subsequent anticancer chemotherapy to treat residual or progressive disease whichever occurred first.

  2. Complete Remission (CR) Rate Per IRF at End of Treatment (EOT) [ Time Frame: Up to 8.34 months ]
    The count of participants with CR per IRF following the completion of study treatment (at end of treatment or at the first assessment after the last dose of study treatment and prior to long-term follow-up) according to the Revised Response Criteria for Malignant Lymphoma.

  3. Overall Survival (OS) [ Time Frame: Up to 90 months ]
    The time from randomization to death due to any cause.

  4. Objective Response Rate (ORR) Per IRF at End of Treatment [ Time Frame: Up to 8.34 months ]
    The count of participants with CR or partial response (PR) per IRF following the completion of study treatment (at end of treatment or the first assessment after the last dose of study treatment and prior to long-term follow-up) according to the Revised Response Criteria for Malignant Lymphoma.

  5. Incidence of Adverse Events (AEs) [ Time Frame: Up to 8.28 months ]
    Any untoward medical occurrence in a clinical investigational participant administered a medicinal product which does not necessarily have a causal relationship with this treatment.

  6. Incidence of Laboratory Abnormalities [ Time Frame: Up to 8.28 months ]
    Number of participants who experienced a Grade 3 or higher laboratory toxicity.
