Description of intervention(s) / exposure
Treatment: Drugs - Idelalisib
Treatment: Drugs - Ofatumumab

Experimental: Idelalisib+ofatumumab - Randomized Initial Therapy (24 weeks): Idelalisib + ofatumumab for a total of 12 infusions (300 mg on Day 1, followed by 1000 mg weekly for 7 weeks, and then 1000 mg every 4 weeks for 4 doses)

Continuing Therapy/Observation: Idelalisib 150 mg tablets twice daily until the earliest of participant withdrawal from study, definitive progression of CLL, intolerable idelalisib-related toxicity, pregnancy or initiation of breast feeding, substantial noncompliance with study procedures, or study discontinuation.

Long-Term Follow-up: Participants were followed for up to 5 years. Information on medical status, anti-tumor treatments, secondary malignancies, and survival status were collected annually during a routine clinic visit or other contact, such as telephone.

Active comparator: Ofatumumab - Randomized Initial Therapy (24 weeks): Ofatumumab for a total of 12 infusions (300 mg on Day 1, followed by 2000 mg weekly for 7 weeks, and then 2000 mg every 4 weeks for 4 doses)

Continuing Therapy/Observation: Observation until the earliest of participant withdrawal from study, definitive progression of CLL, intolerable idelalisib-related toxicity, pregnancy or initiation of breast feeding, substantial noncompliance with study procedures, or study discontinuation.

Long-Term Follow-up: Participants were followed for up to 5 years. Information on medical status, anti-tumor treatments, secondary malignancies, and survival status were collected annually during a routine clinic visit or other contact, such as telephone.
