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

Arm Intervention/treatment
Arm A Post-Chlorambucil Therapy Followup
Patients randomized to Chlorambucil in the parent study(PCYC-1115-CA) who have not progressed at the time of parent study closure will be transferred to this Arm. Follow-up will continue until PD, unacceptable toxicity, or other reason for treatment discontinuation.
 Drug: Post-Chlorambucil Therapy Follow-up
Patients remain in this Arm for continued follow-up until PD, unacceptable toxicity, or other reason for treatment discontinuation. All patients in this Arm have completed Chlorambucil therapy. Patients who have progression will exit the study.

Drug: Alternative Anticancer Treatment
Specific therapy and treatment regimen are at the Investigator's discretion.
Experimental: Arm B Ibrutinib
Patients randomized to Ibrutinib in the parent study (PCYC-1115-CA) who have not experienced PD at the time of parent study closure will be transferred to this Arm to continue on Ibrutinib treatment. Treatment will continue until PD, unacceptable toxicity, or other reasons for treatment discontinuation.
 Drug: Ibrutinib
Ibrutinib 420 mg (3 x 140-mg capsules) is administered orally once daily.
Other Name: PCI-32765

Drug: Alternative Anticancer Treatment
Specific therapy and treatment regimen are at the Investigator's discretion.
Experimental: Arm C Second-line Ibrutinib
Patients who received Chlorambucil in the parent study (PCYC-1115-CA) and experienced PD are transferred to this Arm for Ibrutinib treatment. Treatment will continue until PD, unacceptable toxicity, or other reasons for treatment discontinuation.
 Drug: Second-line Ibrutinib
Patients in this arm who were previously eligible to receive Second-line Ibrutinib will exit the study with option to roll-over to another long-term Ibrutinib study, if eligible.
Other Name: PCI-32765

Drug: Alternative Anticancer Treatment
Specific therapy and treatment regimen are at the Investigator's discretion.
Arm D Alternative Anticancer Therapy
At the Investigator's discretion, alternative anticancer treatment is a therapeutic option for patients who experienced PD during Ibrutinib treatment or during or after Chlorambucil treatment. This Arm can also be considered if drug is discontinued for other reasons (e.g., intolerability or adverse event [AE]) or prior to experiencing PD).
 Drug: Alternative Anti-cancer Treatment
Specific therapy and treatment regimen are at the Investigator's discretion. Patients originally randomized to Chlorambucil will exit the study. Patients originally randomized to Ibrutinib will continue on study.


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 (PFS) [ Time Frame: 10 years ]
    To monitor progression-free survival (PFS)

  2. Safety as measured by all AEs and SAEs for patients randomized to Arm B (Ibrutinib) in Study PCYC-1115-CA [ Time Frame: 10 years ]
    To continue treatment and safety assessment of patients randomized to Arm B (Ibrutinib) in Study PCYC-1115-CA (the parent study) who have not progressed at the time of parent study closure

  3. Long-term follow-up and Second-line therapy monitoring [ Time Frame: 10 years ]
    To follow patients for long-term outcome

  4. Efficacy evaluation of subsequent therapy [ Time Frame: 10 years ]
    To capture overall response rate (ORR), duration of response (DOR), PFS, and overall survival (OS) to subsequent therapy, and time to next therapy, in patients progressing in the parent study
