NORTH CHICAGO, IL, USA I December 2, 2018 I AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced the results of up to seven years of clinical trial follow-up for IMBRUVICA® (ibrutinib) monotherapy in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), the longest follow-up for a Bruton’s tyrosine kinase (BTK) inhibitor to date. The updated Phase 1b/2 data demonstrated durable responses in CLL/SLL patients with an overall response rate (ORR) of 89 percent. Evaluated patients included those with high-risk genomic factors such as complex karyotype and unmutated IGHV, and more than 70 patients with three to 12 prior lines of therapy. Progression-free survival (PFS) rates were also sustained (estimated seven-year rates of 80% for previously untreated patients; 32% in the highly pre-treated relapsed/refractory [R/R] groups). The analysis also found that PFS trended better for R/R patients when treated with ibrutinib in earlier lines of therapy (after one or two prior lines of therapy versus three or more lines of prior therapy).
These data were presented today at the 2018 American Society of Hematology (ASH) Annual Meeting in San Diego, CA (Abstract #3133). IMBRUVICA is a once-daily, first-in-class BTK inhibitor that is administered orally, and is jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company, and Janssen Biotech, Inc.
“With up to seven years of follow up, IMBRUVICA monotherapy continues to show long-lasting responses and survival benefits in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma,” said Danelle James, M.D., M.A.S., Head of Clinical Science, Pharmacyclics LLC, an AbbVie company. “These results help demonstrate that the benefits of IMBRUVICA can be sustained for many years, which were seen in patients with CLL and SLL that are typically more difficult to treat due to high-risk genomic factors.”
CLL is one of the two most common forms of leukemia in adults and is a type of cancer that can develop from cells in the bone marrow that later mature into certain white blood cells (called lymphocytes).1 While these cancer cells start in the bone marrow, they then later spread into the blood. The prevalence of CLL is approximately 115,000 patients in the U.S. with approximately 20,000 newly diagnosed patients every year.2,3 SLL is a slow-growing lymphoma biologically similar to CLL in which too many immature white blood cells cause lymph nodes to become larger than normal.4 Both CLL and SLL are predominately diseases of the elderly, with a median age at diagnosis ranging from 65-70 years.5
“The long-term follow-up data with ibrutinib continues to look promising, with remissions that suggest patients are able to live many years beyond what was previously expected,” said John C. Byrd, M.D., Warren Brown Chair of Leukemia Research, Professor of Medicine at the Ohio State University and the lead investigator of the seven-year follow-up study. “These data also suggest that starting treatment with ibrutinib as early as possible for CLL and SLL provides the best efficacy over the long-term – an important factor that treating physicians should consider.”
About Abstract #3133: Up to 7 Years of Follow-up of Single-Agent Ibrutinib in the Phase 1b/II PCYC-1102 Trial of First Line and Relapsed/Refractory Patients with Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Poster presentation: Sunday, December 2 at 6:00 p.m. PST
In the PCYC-1102 and PCYC-1103 studies, newly diagnosed and R/R CLL/SLL patients, including those with high-risk features, received IMBRUVICA with up to seven years of follow up (n=132).
ORR was 89 percent for all patients (complete response [CR], 15%), with similar rates in previously untreated (87%) and R/R patients (89%). CR rates were higher in previously untreated patients (32%) than in R/R patients (10%). Median duration of response (DOR) was not reached (95% confidence interval [CI]: 0+-85+) for newly diagnosed patients but was 57 months (95% CI: 0+-85+) for R/R patients. Median PFS was not reached (95% CI: NE-NE) for newly diagnosed patients and was 51 months (95% CI: 37-70) for R/R patients. Estimated seven-year PFS rates were 80 percent and 32 percent for newly diagnosed and R/R patients, respectively. Median overall survival (OS) was not reached in newly diagnosed (95% CI: 80-NE months) or R/R patients (95% CI: 63-NE months), with estimated seven-year OS rates of 75 percent and 52 percent, respectively.
High grade adverse events (AEs) were reported in 74 percent of newly diagnosed patients and 89 percent of R/R patients. Hypertension (newly diagnosed, 32%; R/R, 26%), diarrhea (newly diagnosed, 16%; R/R, 4%) and hyponatremia (newly diagnosed, 10%; R/R, 0%) were among the most common grade 3 or higher treatment-emergent AEs. Major hemorrhage and grade 3 or higher atrial fibrillation, thrombocytopenia, anemia and arthralgia were observed in 11 percent or less of newly diagnosed and R/R patients. In addition, infection (newly diagnosed, 23%; R/R, 55%) was more common in R/R patients. No new or unexpected AEs were observed, and the occurrence of most grade 3 or higher AEs and serious AEs decreased over time, with the exception of hypertension.
Additional presentation on ibrutinib monotherapy in CLL at ASH 2018
Additional data presented at ASH include a sub-analysis derived from patients with R/R CLL enrolled in the RESONATE™ trial. The sub-analysis assessed the effects of ibrutinib versus ofatumumab on T-cell function (including degranulation and cytokine release) and proliferation. CLL is a B-cell malignancy that is also characterized by profound immune dysregulation, including dysfunctional T cells. These data will also be presented at ASH on December 2 (abstract #3114).

About IMBRUVICA
IMBRUVICA (ibrutinib) is a first-in-class, oral, once-daily therapy that mainly works by inhibiting a protein called Bruton’s tyrosine kinase (BTK). BTK is a key signaling molecule in the B-cell receptor signaling complex that plays an important role in the survival and spread of malignant B cells.6 IMBRUVICA blocks signals that tell malignant B-cells to multiply and spread uncontrollably.
IMBRUVICA is FDA-approved in six distinct patient populations: chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenström’s macroglobulinemia (WM), along with previously-treated mantle cell lymphoma (MCL), previously-treated marginal zone lymphoma (MZL) and previously-treated chronic graft-versus-host disease (cGVHD).7
- IMBRUVICA was first approved for adult patients with MCL who have received at least one prior therapy in November 2013.
- Soon after, IMBRUVICA was approved in adult CLL patients who have received at least one prior therapy in February 2014. By July 2014, the therapy received approval for adult CLL patients with 17p deletion, and by March 2016, the therapy was approved as a frontline CLL treatment.
- IMBRUVICA was approved for adult patients with WM in January 2015.
- In May 2016, IMBRUVICA was approved in combination with bendamustine and rituximab (BR) for adult patients with CLL/SLL.
- In January 2017, IMBRUVICA was approved for adult patients with MZL who require systemic therapy and have received at least one prior anti-CD20-based therapy.
- In August 2017, IMBRUVICA was approved for adult patients with cGVHD that failed to respond to one or more lines of systemic therapy.
- In August 2018, IMBRUVICA plus rituximab was approved for adult patients with WM.
Accelerated approval was granted for the MCL and MZL indications based on overall response rate. Continued approval for MCL and MZL may be contingent upon verification and description of clinical benefit in confirmatory trials.
IMBRUVICA has been granted four Breakthrough Therapy Designations from the U.S. FDA. This designation is intended to expedite the development and review of a potential new drug for serious or life-threatening diseases.8 IMBRUVICA was one of the first medicines to receive FDA approval via the new Breakthrough Therapy Designation pathway.
IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers and other serious illnesses. IMBRUVICA has one of the most robust clinical oncology development programs for a single molecule in the industry, with more than 130 ongoing clinical trials. There are approximately 30 ongoing company-sponsored trials, 14 of which are in Phase 3, and more than 100 investigator-sponsored trials and external collaborations that are active around the world. To date, more than 135,000 patients around the world have been treated with IMBRUVICA in clinical practice and clinical trials.
