- New results from the Phase 2 CAPTIVATE clinical trial show the potential of this fixed-duration, combination therapy for CLL patients starting treatment for the first time
- Data will be presented at an oral presentation session at the 2019 American Society of Hematology (ASH) Annual Meeting (abstract #35)
NORTH CHICAGO, Ill., Dec. 7, 2019 /PRNewswire/ -- AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced new data from the Phase 2 CAPTIVATE (PCYC-1142) clinical trial,1 evaluating IMBRUVICA® (ibrutinib) in combination with VENCLEXTA®/VENCLYXTO® (venetoclax) in previously untreated patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Results showed that patients who received up to 12 cycles of the combination regimen achieved high rates of undetectable minimal residual disease (uMRD) in both peripheral blood (PB; 75 percent of patients) and in bone marrow (BM; 72 percent of patients). Safety data were consistent with the known safety profiles of IMBRUVICA and VENCLEXTA/VENCLYXTO used as individual therapies.
According to the Leukemia & Lymphoma Society, MRD refers to the small number of cancer cells that remain in the body after treatment. The number of remaining cells may be so small that they do not cause any physical signs or symptoms and often cannot even be detected through traditional methods. Doctors use MRD to measure the effectiveness of treatment and to predict which patients are at risk of relapse.
"The oral regimen of ibrutinib alone followed by combined ibrutinib and venetoclax delivered a promising rate of disease clearance in previously untreated patients with CLL, with 75 percent and 72 percent of patients having undetectable disease (MRD) in the blood and bone marrow, respectively," said Constantine Tam, M.D., Hematologist and Disease Group Lead, Low Grade Lymphoma and CLL at Peter MacCallum Cancer Centre, Victoria, Australia, and lead study investigator of CAPTIVATE. "We are encouraged by these data and the potentially potent combination of ibrutinib plus venetoclax treatment for CLL and potentially other blood cancers in the future."
The data were presented today during an oral presentation session at the 2019 American Society of Hematology (ASH) Annual Meeting (abstract #35). Results from the MRD-guided, randomized treatment discontinuation cohort and fixed duration cohort of the CAPTIVATE clinical trial are currently being evaluated and will be presented at a future medical meeting.
"While IMBRUVICA and VENCLEXTA/VENCLYXTO-based treatments are the established standard-of-care for different CLL patients today, an IMBRUVICA plus VENCLEXTA/VENCLYXTO combination treatment could be a new and innovative option for patients, as evidenced by the positive results from the CAPTIVATE clinical trial," said Mohamed Zaki, M.D., Ph.D., Head of Hematology Oncology, AbbVie. "We are pleased with the results from this CLL treatment combination and look forward to sharing additional analyses in the future."
IMBRUVICA is a once-daily, first-in-class Bruton's tyrosine kinase (BTK) inhibitor that is administered orally, and is jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company, and Janssen Biotech, Inc.
VENCLEXTA/VENCLYXTO is a first-in-class medicine that selectively binds and inhibits the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers, BCL-2 prevents cancer cells from undergoing their natural death or self-destruction process, called apoptosis. VENCLEXTA/VENCLYXTO targets the BCL-2 protein and works to help restore the process of apoptosis. VENCLEXTA/VENCLYXTO is being developed by AbbVie and Roche. It is jointly commercialized by AbbVie and Genentech, a member of the Roche Group, in the U.S. and by AbbVie outside of the U.S. Together, the companies are committed to BCL-2 research and to studying venetoclax in clinical trials across several blood and other cancers.
Abstract #35: Ibrutinib Plus Venetoclax for First-line Treatment of Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma (CLL/SLL): Results from Minimal Residual Disease (MRD) Cohort of Phase 2 CAPTIVATE Study
Oral Presentation: Saturday, December 7 at 8:30 a.m. EST
The Phase 2 CAPTIVATE (PCYC-1142) clinical trial evaluated 164 patients younger than 70 years (median age of 58 years) with previously untreated CLL/SLL. Ninety-two percent of patients (n=151) were randomly assigned to receive IMBRUVICA monotherapy as lead-in treatment for 3 cycles. Following, all patients completed 12 cycles of IMBRUVICA plus VENCLEXTA/VENCLYXTO combination regimen. MRD status was evaluated in PB after 6, 9, and 12 cycles and in BM after 12 cycles of IMBRUVICA plus VENCLEXTA/VENCLYXTO.
Results showed uMRD – defined as less than 1 CLL cell per 10,000 leukocytes (MRD<0.01 percent) by flow cytometry of PB or BM samples – was achieved at any time after baseline in PB for 75 percent of patients (122 of 163 patients) and in BM for 72 percent (111 of 155 patients). The proportion of patients who had uMRD in PB increased over time from 57 percent after 6 cycles, 68 percent after 9 cycles, and 73 percent after 12 cycles of IMBRUVICA plus VENCLEXTA/VENCLYXTO. The high rates of uMRD in BM were consistent across high-risk subgroups, including in patients with del(17p), del(17p) or TP53 mutation, del(11q), complex karyotype, and unmutated IGHV status. In patients with uMRD in PB with matched BM samples, 93 percent of patients had uMRD in both PB and BM. With median follow-up of 14.7 months, 3 patients (2 percent) experienced disease progression.
The most common adverse events (AEs) of any grade (in 20 percent of patients or greater) were diarrhea (31 percent) and arthralgia (22 percent) during treatment with IMBRUVICA alone; and diarrhea (60 percent), neutropenia (40 percent), nausea (34 percent), upper respiratory tract infection (24 percent), and fatigue (20 percent) during treatment with IMBRUVICA plus VENCLEXTA/VENCLYXTO. AEs leading to dose reductions occurred in 20 percent of patients overall (IMBRUVICA: 14 percent; VENCLEXTA/VENCLYXTO: 9 percent). AEs leading to discontinuation were infrequent, occurring in 5 percent of patients overall (IMBRUVICA: 6 percent; VENCLEXTA/VENCLYXTO: 4 percent).
About IMBRUVICA® (ibrutinib)
IMBRUVICA (ibrutinib) is an oral, once-daily medicine that works differently than chemotherapy as it blocks a protein called Bruton's tyrosine kinase (BTK). The BTK protein sends important signals that tell B cells to mature and produce antibodies. BTK signaling is needed by specific cancer cells to multiply and spread.2.3 By blocking BTK, IMBRUVICA may help move abnormal B cells out of their nourishing environments in the lymph nodes, bone marrow, and other organs.4
Since its launch in 2013, IMBRUVICA has received 10 FDA approvals across six disease areas: chronic lymphocytic leukemia (CLL) with or without 17p deletion (del17p); small lymphocytic lymphoma (SLL) with or without del17p; Waldenström's macroglobulinemia (WM); previously-treated patients with mantle cell lymphoma (MCL)*; previously-treated patients with marginal zone lymphoma (MZL) who require systemic therapy and have received at least one prior anti-CD20-based therapy* – and previously-treated patients with chronic graft-versus-host disease (cGVHD) after failure of one or more lines of systemic therapy.5
IMBRUVICA is now approved in 95 countries and has been used to treat more than 170,000 patients worldwide across its approved indications. IMBRUVICA is the only FDA-approved medicine in WM and cGVHD. 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. IMBRUVICA was one of the first medicines to receive FDA approval via the Breakthrough Therapy Designation pathway.
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for CLL recommends ibrutinib (IMBRUVICA®) as a preferred regimen for the initial treatment of CLL/SLL and it is the only Category 1 single-agent regimen for treatment-naïve patients without deletion 17p.
IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers and other serious illnesses. IMBRUVICA is the most comprehensively studied BTK inhibitor, with more than 150 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. For more information, visit www.IMBRUVICA.com.
*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 IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA®. Major hemorrhage (≥ Grade 3, serious, or any central nervous system events; e.g., intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post procedural hemorrhage) have occurred in 4% of patients, with fatalities occurring in 0.4% of 2,838 patients exposed to IMBRUVICA® in 27 clinical trials. Bleeding events of any grade, including bruising and petechiae, occurred in 39% of patients treated with IMBRUVICA®.
The mechanism for the bleeding events is not well understood.
Use of either anticoagulant or antiplatelet agents concomitantly with IMBRUVICA® increases the risk of major hemorrhage. In IMBRUVICA® clinical trials, 3.1% of patients taking IMBRUVICA® without antiplatelet or anticoagulant therapy experienced major hemorrhage. The addition of antiplatelet therapy with or without anticoagulant therapy increased this percentage to 4.4%, and the addition of anticoagulant therapy with or without antiplatelet therapy increased this percentage to 6.1%. Consider the risks and benefits of anticoagulant or antiplatelet therapy when co-administered with IMBRUVICA®. Monitor for signs and symptoms of bleeding.
Consider the benefit-risk of withholding IMBRUVICA® for at least 3 to 7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding.
Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with IMBRUVICA® therapy. Grade 3 or greater infections occurred in 24% of 1,124 patients exposed to IMBRUVICA® in clinical trials. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA®. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.
Monitor and evaluate patients for fever and infections and treat appropriately.
Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (23%), thrombocytopenia (8%), and anemia (3%) based on laboratory measurements occurred in patients with B‑cell malignancies treated with single agent IMBRUVICA®.
Monitor complete blood counts monthly.
Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with IMBRUVICA® therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0.2% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 4% of 1,124 patients exposed to IMBRUVICA® in clinical trials. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias.
Periodically monitor patients clinically for cardiac arrhythmias. Obtain an ECG for patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness, syncope, chest pain) or new onset dyspnea. Manage cardiac arrhythmias appropriately, and if it persists, consider the risks and benefits of IMBRUVICA® treatment and follow dose modification guidelines.
Hypertension: Hypertension of any grade occurred in 12% of 1,124 patients treated with IMBRUVICA® in clinical trials. Grade 3 or greater hypertension occurred in 5% of patients with a median time to onset of 5.9 months (range, 0.03 to 24 months).
Monitor blood pressure in patients treated with IMBRUVICA® and initiate or adjust anti-hypertensive medication throughout treatment with IMBRUVICA® as appropriate.
Second Primary Malignancies: Other malignancies (10%) including non-skin carcinomas (4%) have occurred in 1,124 patients treated with IMBRUVICA® in clinical trials. The most frequent second primary malignancy was non-melanoma skin cancer (6%).
Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA® therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions.
Monitor patients closely and treat as appropriate.
Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA® can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICA® and for 1 month after cessation of therapy. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Advise men to avoid fathering a child during the same time period.
B-cell malignancies: The most common adverse reactions (≥20%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were thrombocytopenia (58%)*, diarrhea (41%), anemia (38%)*, neutropenia (35%)*, musculoskeletal pain (32%), rash (32%), bruising (31%), nausea (26%), fatigue (26%), hemorrhage (24%), and pyrexia (20%).
The most common Grade 3 or 4 adverse reactions (≥5%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were neutropenia (18%)*, thrombocytopenia (16%)*, and pneumonia (14%).
Approximately 7% (CLL/SLL), 14% (MCL), 14% (WM) and 10% (MZL) of patients had a dose reduction due to adverse reactions. Approximately 4-10% (CLL/SLL), 9% (MCL), and 7% (WM [5%] and MZL [13%]) of patients discontinued due to adverse reactions.
cGVHD: The most common adverse reactions (≥20%) in patients with cGVHD were fatigue (57%), bruising (40%), diarrhea (36%), thrombocytopenia (33%)*, muscle spasms (29%), stomatitis (29%), nausea (26%), hemorrhage (26%), anemia (24%)*, and pneumonia (21%).
The most common Grade 3 or higher adverse reactions (≥5%) reported in patients with cGVHD were pneumonia (14%), fatigue (12%), diarrhea (10%), neutropenia (10%)*, sepsis (10%), hypokalemia (7%), headache (5%), musculoskeletal pain (5%), and pyrexia (5%).
Twenty-four percent of patients receiving IMBRUVICA® in the cGVHD trial discontinued treatment due to adverse reactions. Adverse reactions leading to dose reduction occurred in 26% of patients.
*Treatment-emergent decreases (all grades) were based on laboratory measurements.
CYP3A Inhibitors: Co-administration of IMBRUVICA® with strong or moderate CYP3A inhibitors may increase ibrutinib plasma concentrations. Dose modifications of IMBRUVICA® may be recommended when used concomitantly with posaconazole, voriconazole, and moderate CYP3A inhibitors. Avoid concomitant use of other strong CYP3A inhibitors. Interrupt IMBRUVICA® if strong inhibitors are used short-term (e.g., for ≤ 7 days). See dose modification guidelines in USPI sections 2.4 and 7.1.
CYP3A Inducers: Avoid coadministration with strong CYP3A inducers.
Hepatic Impairment (based on Child-Pugh criteria): Avoid use of IMBRUVICA® in patients with severe baseline hepatic impairment. In patients with mild or moderate impairment, reduce IMBRUVICA® dose.

VENCLEXTA is a prescription medicine used:
- to treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
- in combination with azacitidine, or decitabine, or low-dose cytarabine to treat adults with newly-diagnosed acute myeloid leukemia (AML) who:
VENCLEXTA was approved based on response rates. Continued approval for this use may depend on the results of an ongoing study to find out how VENCLEXTA works over a longer period of time.
It is not known if VENCLEXTA is safe and effective in children.
Important Safety Information
What is the most important information I should know about VENCLEXTA?
VENCLEXTA can cause serious side effects, including:
Tumor lysis syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure, the need for dialysis treatment, and may lead to death. Your healthcare provider will do tests to check your risk of getting TLS before you start taking VENCLEXTA. You will receive other medicines before starting and during treatment with VENCLEXTA to help reduce your risk of TLS. You may also need to receive intravenous (IV) fluids into your vein. Your healthcare provider will do blood tests to check for TLS when you first start treatment and during treatment with VENCLEXTA. It is important to keep your appointments for blood tests. Tell your healthcare provider right away if you have any symptoms of TLS during treatment with VENCLEXTA, including fever, chills, nausea, vomiting, confusion, shortness of breath, seizures, irregular heartbeat, dark or cloudy urine, unusual tiredness, or muscle or joint pain.
Drink plenty of water during treatment with VENCLEXTA to help reduce your risk of getting TLS. Drink 6 to 8 glasses (about 56 ounces total) of water each day, starting 2 days before your first dose, on the day of your first dose of VENCLEXTA, and each time your dose is increased.
Your healthcare provider may delay, decrease your dose, or stop treatment with VENCLEXTA if you have side effects.
Who should not take VENCLEXTA?
Certain medicines must not be taken when you first start taking VENCLEXTA and while your dose is being slowly increased because of the risk of increased TLS.
- Tell your healthcare provider about all the medicines you take, including prescription and over-the- counter medicines, vitamins, and herbal supplements. VENCLEXTA and other medicines may affect each other causing serious side effects.
- Do not start new medicines during treatment with VENCLEXTA without first talking with your healthcare provider.
Before taking VENCLEXTA, tell your healthcare provider about all of your medical conditions, including if you:
- have kidney or liver problems.
- have problems with your body salts or electrolytes, such as potassium, phosphorus, or calcium.
- have a history of high uric acid levels in your blood or gout.
- are scheduled to receive a vaccine. You should not receive a "live vaccine" before, during, or after treatment with VENCLEXTA, until your healthcare provider tells you it is okay. If you are not sure about the type of immunization or vaccine, ask your healthcare provider. These vaccines may not be safe or may not work as well during treatment with VENCLEXTA.
- are pregnant or plan to become pregnant. VENCLEXTA may harm your unborn baby. If you are able to become pregnant, your healthcare provider should do a pregnancy test before you start treatment with VENCLEXTA, and you should use effective birth control during treatment and for at least 30 days after the last dose of VENCLEXTA. If you become pregnant or think you are pregnant, tell your healthcare provider right away.
- are breastfeeding or plan to breastfeed. It is not known if VENCLEXTA passes into your breast milk. Do not breastfeed during treatment with VENCLEXTA.
What should I avoid while taking VENCLEXTA?
You should not drink grapefruit juice or eat grapefruit, Seville oranges (often used in marmalades), or starfruit while you are taking VENCLEXTA. These products may increase the amount of VENCLEXTA in your blood.
What are the possible side effects of VENCLEXTA?
VENCLEXTA can cause serious side effects, including:
- Low white blood cell counts (neutropenia). Low white blood cell counts are common with VENCLEXTA, but can also be severe. Your healthcare provider will do blood tests to check your blood counts during treatment with VENCLEXTA.
- Infections. Death and serious infections such as pneumonia and blood infection (sepsis) have happened during treatment with VENCLEXTA. Your healthcare provider will closely monitor and treat you right away if you have a fever or any signs of infection during treatment with VENCLEXTA.
Tell your healthcare provider right away if you have a fever or any signs of an infection during treatment with VENCLEXTA.
The most common side effects of VENCLEXTA when used in combination with obinutuzumab or rituximab or alone in people with CLL or SLL include low white blood cell counts; low platelet counts; low red blood cell counts; diarrhea; nausea; upper respiratory tract infection; cough; muscle and joint pain; tiredness; and swelling of your arms, legs, hands, and feet.
The most common side effects of VENCLEXTA in combination with azacitidine or decitabine or low-dose cytarabine in people with AML include low white blood cell counts; nausea; diarrhea; low platelet counts; constipation; fever with low white blood cell counts; low red blood cell counts; infection in blood; rash; dizziness; low blood pressure; fever; swelling of your arms, legs, hands, and feet; vomiting; tiredness; shortness of breath; bleeding; infection in lung; stomach (abdominal) pain; pain in muscles or back; cough; and sore throat.
VENCLEXTA may cause fertility problems in males. This may affect your ability to father a child. Talk to your healthcare provider if you have concerns about fertility.
These are not all the possible side effects of VENCLEXTA. For more information, ask your healthcare provider or pharmacist.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
If you cannot afford your medication, contact www.medicineassistancetool.org for assistance.

Indication and Important VENCLYXTO (venetoclax) EU Safety Information7
Venclyxto in combination with rituximab is indicated for the treatment of adult patients with chronic lymphocytic leukaemia (CLL) who have received at least one prior therapy.
Venclyxto monotherapy is indicated for the treatment of CLL:
- in the presence of 17p deletion or TP53 mutation in adult patients who are unsuitable for or have failed a B-cell receptor pathway inhibitor, or
- in the absence of 17p deletion or TP53 mutation in adult patients who have failed both chemoimmunotherapy and a B-cell receptor pathway inhibitor.
Hypersensitivity to the active substance or to any of the excipients is contraindicated. Concomitant use of strong CYP3A inhibitors at initiation and during the dose-titration phase due to increased risk for tumor lysis syndrome (TLS). Concomitant use of preparations containing St. John's wort as VENCLYXTO efficacy may be reduced.
Special Warnings & Precautions for Use
Tumor lysis syndrome (TLS), including fatal events, has occurred in patients with previously treated CLL with high tumor burden when treated with VENCLYXTO. VENCLYXTO poses a risk for TLS in the initial 5-week dose-titration phase. Changes in electrolytes consistent with TLS that require prompt management can occur as early as 6 to 8 hours following the first dose of VENCLYXTO and at each dose increase. Patients should be assessed for risk and should receive appropriate prophylaxis, monitoring, and management for TLS.
Neutropenia (grade 3 or 4) has been reported and complete blood counts should be monitored throughout the treatment period. Serious infections including events of sepsis with fatal outcome have been reported. Supportive measures including antimicrobials for any signs of infection should be considered.
Live vaccines should not be administered during treatment or thereafter until B-cell recovery.
CYP3A inhibitors may increase VENCLYXTO plasma concentrations. At initiation and dose-titration phase: Strong CYP3A inhibitors are contraindicated due to increased risk for TLS and moderate CYP3A inhibitors should be avoided. If moderate CYP3A inhibitors must be used, physicians should refer to the SmPC for dose adjustment recommendations. At steady daily dose: If moderate or strong CYP3A inhibitors must be used, physicians should refer to the SmPC for dose adjustment recommendations.
Avoid concomitant use of P-gp and BCRP inhibitors at initiation and during the dose titration phase.
CYP3A4 inducers may decrease VENCLYXTO plasma concentrations. Avoid coadministration with strong or moderate CYP3A inducers. These agents may decrease venetoclax plasma concentrations.
Co-administration of bile acid sequestrants with VENCLYXTO is not recommended as this may reduce the absorption of VENCLYXTO.
The most commonly occurring adverse reactions (>=20%) of any grade in patients receiving venetoclax in the combination study with rituximab were neutropenia, diarrhea, and upper respiratory tract infection. In the monotherapy studies, the most common adverse reactions were neutropenia/neutrophil count decreased, diarrhea, nausea, anemia, fatigue, and upper respiratory tract infection.
The most frequently occurring serious adverse reactions (>=2%) in patients receiving venetoclax in combination with rituximab or as monotherapy were pneumonia, febrile neutropenia and TLS.
Discontinuation due to adverse reactions occurred in 16% of patients receiving venetoclax plus rituximab and 9% receiving venetoclax monotherapy. Dosage adjustments due to adverse reactions occurred in 15% of patients receiving venetoclax plus rituximab and 2% receiving venetoclax monotherapy. Dose interruptions occurred in 71% of patients treated with the combination of venetoclax and rituximab.
Patients with reduced renal function (CrCl <80 mL/min) may require more intensive prophylaxis and monitoring to reduce the risk of TLS. Safety in patients with severe renal impairment (CrCl <30 mL/min) or on dialysis has not been established, and a recommended dose for these patients has not been determined. For patients with severe (Child-Pugh C) hepatic impairment, a dose reduction of at least 50% throughout treatment is recommended.
VENCLYXTO may cause embryo-fetal harm when administered to a pregnant woman. Advise nursing women to discontinue breastfeeding during treatment.
