in 1L CLL with high-risk patients1-6

La Verne 1L CLL Patient

I found out, through a genetic test, that I had CLL with a chromosome deletion of 17p, which my doctor explained meant I had a very poor prognosis."

E1912: open-label, phase 3 trial in treatment-naïve patients (N=529) with CLL/SLL ≤70 years of age, randomized 2:1 to receive IMBRUVICA®* + rituximab† (n=354) or FCR‡§ (n=175). Patients with del 17p were excluded.5

iLLUMINATE™: phase 3, multicenter, open-label trial of 1L CLL/SLL patients (N=229) ≥65 years or 1L CLL/SLL patients <65 years of age with at least one of the following conditions: coexisting medical conditions, reduced renal function as measured by creatinine clearance <70 mL/min, or del 17p/TP53 mutation. Patients were randomized 1:1 to IMBRUVICA® 420 mg once daily until disease progression or unacceptable toxicity in combination with obinutuzumab (n=113) or chlorambucil in combination with obinutuzumab (n=116).2,5

RESONATE™-2: phase 3, multicenter, open-label trial of 1L CLL/SLL patients (N=269) ≥65 years of age who were randomized 1:1 to IMBRUVICA® 420 mg once daily until disease progression or unacceptable toxicity (n=136) or chlorambucil (n=133) for up to 12 cycles. Patients with del 17p were excluded.3,5

ALLIANCE A041202: phase 3, multicenter, open-label trial of 1L CLL patients (N=547) ≥65 years of age who were randomized 1:1:1 to IMBRUVICA® 420 mg once daily until disease progression or unacceptable toxicity (n=182), bendamustine at 90 mg/m2 on days 1 and 2 of each 28-day cycle for 6 cycles + rituximab (n=183), or IMBRUVICA® 420 mg once daily until disease progression or unacceptable toxicity + rituximab (n=182). It was coordinated by the Alliance for Clinical Trials in Oncology.4

The data from the ALLIANCE A041202 study have not been reviewed by the FDA and are not included in the IMBRUVICA® Prescribing Information.

420 mg once daily until disease progression or unacceptable toxicity.

†Rituximab initiated in cycle 2 for the IMBRUVICA® + rituximab arm and in cycle 1 for the FCR arm, and administered at 50 mg/m2 on day 1 of the first cycle, 325 mg/m2 on day 2 of the first cycle, and 500 mg/m2 on day 1 of 5 subsequent cycles, for a total of 6 cycles.

‡Fludarabine 25 mg/m2 on days 1, 2, and 3 of cycles 1-6.

§Cyclophosphamide 250 mg/m2 on days 1, 2, and 3 of cycles 1-6.
