What was measured

The overall response rate (ORR) is defined as the proportion of participants with an overall response (complete remission \[CR\] + complete remission with incomplete marrow recovery \[CRi\] + nodular partial remission \[nPR\] + partial remission \[PR\]) per the 2008 Modified International Workshop for Chronic Lymphocytic Leukemia (IWCLL)/National Cancer Institute-Working Group (NCI-CWG) criteria as assessed by the Independent Review Committee (IRC) in the first 70 participants treated in the Main Cohort.

Analysis population: The first 70 participants who were treated with ABT-199 in the Main Cohort

Groups in this outcome

Main Cohort

Participants received ABT-199 tablets once daily (QD) orally for up to 79 months. The starting dose was 20 mg daily, increasing over a period of 5 weeks up to the daily dose of 400 mg.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.

  1. group Description
    The ORR for ABT-199 was tested to reject the null hypothesis of ORR = 40%. If the null hypothesis is rejected and the ORR is higher than 40%, then ABT-199 has been shown to have an ORR significantly higher than 40%.The p-value is from the exact binomial distribution comparing ABT-199 ORR to the 40% historical control rate.
