OVERVIEW

ABBV-319 is an investigational drug under clinical development. Safety and efficacy have not been established.

ABBV-319 is a CD19-GRM antibody-drug conjugate (ADC) composed of an optimized high-affinity immunoglobulin G1 antibody conjugated to a potent proprietary glucocorticosteroid payload.

PROPOSED MECHANISM OF ACTION

Systemic glucocorticosteroids (ie, glucocorticoid receptor modulators [GRMs]) show robust monotherapy activity against B-cell malignancies at high doses; however, they may be accompanied by steroid-associated toxicities that limit dosing.

CD19 is a marker essential for B-cell proliferation and has high expression across B-cell malignancies including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and chronic lymphocytic leukemia (CLL).

ABBV-319 is a CD19-GRM ADC composed of an optimized high-affinity immunoglobulin G1 antibody conjugated to a potent proprietary glucocorticosteroid payload. ABBV-319 is a multimodal ADC that takes advantage of both:

• Enhanced antibody-dependent cellular cytotoxicity (ADCC) via afucosylation
• Targeted GRM payload delivery to maximize anticancer activity while lowering the risk of systemic steroid toxicities

DEVELOPMENT

ABBV-319 is being investigated in a Phase 1 trial for the treatment of B-cell malignancies, specifically DLBCL, FL and CLL.

OVERVIEW

ABBV-453 is an investigational drug under clinical development. Safety and efficacy have not been established.

ABBV-453 is an oral B-cell lymphoma 2 (BCL-2) inhibitor being investigated in relapsed or refractory (R/R) multiple myeloma (MM) and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). 

PROPOSED MECHANISM OF ACTION

BCL-2 is an anti-apoptotic, pro-survival member of the BCL-2 family of proteins that function to regulate the intrinsic pathway of apoptosis, or programmed cell death, and help maintain cellular homeostasis.^1,2 BCL-2 is a pro-survival oncoprotein that can be overexpressed as a result of cancer-specific mutations or gene amplifications.³

MM is a heterogenous disease with IgH translocations such as t(11;14), t(4;14), t(6;14), t(14;16), and t(14;20) in approximately 40% of MM patients. ⁴ The most common IgH translocation in MM is t(11;14). BCL-2 dependency varies across MM; MM cells with the t(11;14) translocation are primarily dependent on BCL-2 for survival. 

Relatively high levels of BCL-2 expression are documented in 95% of CLL cases compared to normal peripheral blood lymphocytes.⁵

ABBV-453 binds to BCL-2, preventing it from binding to pro-apoptotic proteins and thereby restoring the cell's ability to undergo apoptosis.^6,7

DEVELOPMENT

ABBV-453 is being investigated in Phase 1 trials for the treatment of R/R MM and CLL/SLL.

OVERVIEW

CLBR001+SWI019 is an investigational drug under clinical development. Safety and efficacy have not been established.

CLBR001+SWI019 is a two-component infusion therapy of autologous switchable chimeric antigen receptor-T (sCAR-T) cells (CLBR001) and CD19-targeted antibody Fab switch (SWI019) being investigated in relapsed or refractory (R/R) B-cell malignancies.^1,2,3.

PROPOSED MECHANISM OF ACTION

The CLBR001+SWI019 sCAR-T system consists of two parts, including an autologous cell product composed of a humanized, third generation CAR-T cell (CLBR001) along with a humanized antibody Fab “switch” (SWI019) that is dosed following CLBR001 infusion.  SWI019 is designed to act as a switch to dynamically turn “on” or “off” CLBR001 cells, allowing for controllable activity of the adoptively transferred cells. CLBR001+SWI019 demonstrated target cell cytotoxicity in preclinical models.

DEVELOPMENT

CLBR001+SWI019 is being investigated in a Phase 1 trial for the treatment of R/R B-cell malignancies.

CLBR001/SWI019 developed by Calibr is in a first-in-patient trial and AbbVie hold options for additional development and other targets.

OVERVIEW

Ibrutinib (PCI-32765, CRA-032765) is an approved drug being investigated for additional uses. Safety and efficacy have not been established for these additional uses.

Ibrutinib (PCI-32765, CRA-032765) is a selective, orally bioavailable small-molecule BTK inhibitor.¹

PROPOSED MECHANISM OF ACTION

Ibrutinib (PCI-32765, CRA-032765) is small-molecule inhibitor of Bruton’s tyrosine kinase (BTK). Ibrutinib forms a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity.¹ BTK is a signaling molecule of the B-cell antigen receptor (BCR) and cytokine receptor pathways. BTK’s role in signaling through the B-cell surface receptors results in the activation of pathways necessary for B-cell trafficking, chemotaxis, and adhesion. Nonclinical studies show that ibrutinib inhibits malignant B-cell proliferation and survival in vivo as well as cell migration and substrate adhesion in vitro.²

Ibrutinib also inhibits the activity of interleukin-2-inducible-T-cell kinase (ITK).³

IBRUTINIB Indication and Safety Overview (US PRESCRIBING INFORMATION)⁵

Indication:

Ibrutinib is a kinase inhibitor indicated for the treatment of:

• Adult patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).
• Adult patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) with 17p deletion.
• Adult patients with Waldenström's macroglobulinemia (WM).
• Adult and pediatric patients age 1 year and older with chronic graft versus host disease (cGVHD) after failure of one or more lines of systemic therapy.

SAFETY INFORMATION

Warning and Precautions

• Hemorrhage: Fatal bleeding events have occurred in patients who received ibrutinib. 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) occurred in 4.2% of patients, with fatalities occurring in 0.4% of 2,838 patients who received ibrutinib in 27 clinical trials. Bleeding events of any grade including bruising and petechiae occurred in 39%, and excluding bruising and petechiae occurred in 23% of patients who received ibrutinib, respectively.
  The mechanism for the bleeding events is not well understood.
  Use of either anticoagulant or antiplatelet agents concomitantly with ibrutinib increases the risk of major hemorrhage. Across clinical trials, 3.1% of 2,838 patients who received ibrutinib 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 ibrutinib. Monitor for signs and symptoms of bleeding.
  Consider the benefit-risk of withholding ibrutinib 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 ibrutinib therapy. Grade 3 or greater infections occurred in 21% of 1,476 patients with B-cell malignancies who received ibrutinib in clinical trials. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with ibrutinib. 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.
• Cardiac Arrhythmias, Cardiac Failure, and Sudden Death: Fatal and serious cardiac arrhythmias and cardiac failure have occurred with ibrutinib. Deaths due to cardiac causes or sudden deaths occurred in 1% of 4,896 patients who received ibrutinib in clinical trials, including in patients who received ibrutinib in unapproved monotherapy or combination regimens. These adverse reactions occurred in patients with and without preexisting hypertension or cardiac comorbidities. Patients with cardiac comorbidities may be at greater risk of these events.
  Grade 3 or greater ventricular tachyarrhythmias were reported in 0.2%, Grade 3 or greater atrial fibrillation and atrial flutter were reported in 3.7%, and Grade 3 or greater cardiac failure was reported in 1.3% of 4,896 patients who received ibrutinib in clinical trials, including in patients who received ibrutinib in unapproved monotherapy or combination regimens. These events have occurred particularly in patients with cardiac risk factors including hypertension and diabetes mellitus, a previous history of cardiac arrhythmias, and in patients with acute infections.
  Evaluate cardiac history and function at baseline, and monitor patients for cardiac arrhythmias and cardiac function. Obtain further evaluation (e.g., ECG, echocardiogram) as indicated for patients who develop symptoms of arrhythmia (e.g., palpitations, lightheadedness, syncope, chest pain), new onset dyspnea, or other cardiovascular concerns. Manage cardiac arrhythmias and cardiac failure appropriately, follow dose modification guidelines, and consider the risks and benefits of continued ibrutinib treatment.
• Hypertension: Hypertension occurred in 19% of 1,476 patients with B-cell malignancies who received ibrutinib in clinical trials. Grade 3 or greater hypertension occurred in 8% of patients. Based on data from a subset of these patients, (N=1,124), the median time to onset was 5.9 months (range, 0 to 24 months). In a long-term safety analysis over 5 years of 1,284 patients with B-cell malignancies treated for a median of 36 months (range, 0 to 98 months), the cumulative rate of hypertension increased over time. The prevalence for Grade 3 or greater hypertension was 4% (year 0-1), 7% (year 1-2), 9% (year 2-3), 9% (year 3-4), and 9% (year 4-5); the overall incidence for the 5-year period was 11%. Monitor blood pressure in patients treated with ibrutinib, initiate or adjust anti-hypertensive medication throughout treatment with ibrutinib as appropriate, and follow dosage modification guidelines for Grade 3 or higher hypertension.
• Cytopenias: In 645 patients with B-cell malignancies who received ibrutinib as a single agent, grade 3 or 4 neutropenia occurred in 23% of patients, grade 3 or 4 thrombocytopenia in 8% and grade 3 or 4 anemia in 2.8%, based on laboratory measurements. Monitor complete blood counts monthly.
• Second Primary Malignancies: Other malignancies (10%), including non-skin carcinomas (3.9%), occurred among the 1,476 patients with B-cell malignancies who received ibrutinib in clinical trials. The most frequent second primary malignancy was non-melanoma skin cancer (6%).
• Hepatotoxicity, Including Drug-Induced Liver Injury: Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Bruton tyrosine kinase inhibitors, including ibrutinib.
  Evaluate bilirubin and transaminases at baseline and throughout treatment with ibrutinib. For patients who develop abnormal liver tests after ibrutinib, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold ibrutinib. Upon confirmation of DILI, discontinue ibrutinib.
• Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with ibrutinib. 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, ibrutinib can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ibrutinib and for 1 month after the last dose. Advise males with female partners of reproductive potential to use effective contraception during the same time period.

Adverse Reactions

• B-cell malignancies: The most common adverse reactions (≥30%) in adult patients with B-cell malignancies were thrombocytopenia (55%)*, diarrhea (44%), fatigue (39%), musculoskeletal pain (39%), neutropenia (39%)*, rash (36%), anemia (35%)*, bruising (32%), and nausea (30%).
  The most common Grade ≥ 3 adverse reactions (≥5%) in adult patients with B-cell malignancies were neutropenia (21%)*, thrombocytopenia (14%)*, pneumonia (8%), and hypertension (8%).
  Approximately 9% (CLL/SLL), and 14% (WM) of adult patients had a dose reduction due to adverse reactions. Approximately 4-10% (CLL/SLL) and 5% (WM) of adult patients discontinued due to adverse reactions.
• cGVHD: The most common adverse reactions (≥20%) in adult or pediatric patients with cGVHD were fatigue (57%), anemia (49%)*, bruising (40%), diarrhea (36%), thrombocytopenia (33%)*, musculoskeletal pain (30%), pyrexia (30%), muscle spasms (29%), stomatitis (29%), hemorrhage (26%), nausea (26%), abdominal pain (23%), pneumonia (23%), and headache (21%).
  The most common Grade 3 or higher adverse reactions (≥5%) reported in adult or pediatric patients with cGVHD were pneumonia (14%), anemia (13%)*, fatigue (12%), pyrexia (11%), diarrhea (10%), neutropenia (10%)*, sepsis (10%), osteonecrosis (9%), stomatitis (9%), hypokalemia (7%), headache (5%), and musculoskeletal pain (5%).
  Discontinuation of ibrutinib treatment due to an adverse reaction occurred in 24% of adult patients and 23% of pediatric patients. Adverse reactions leading to dose reduction occurred in 26% of adult patients and 19% of pediatric patients.
  *Treatment-emergent decreases (all grades) were based on laboratory measurements.

Drug Interactions

• CYP3A Inhibitors: Co-administration of ibrutinib with strong or moderate CYP3A inhibitors may increase ibrutinib plasma concentrations. Increased ibrutinib concentrations may increase the risk of drug-related toxicity. Dose modifications of ibrutinib are recommended when used concomitantly with posaconazole, voriconazole, and moderate CYP3A inhibitors. Avoid concomitant use of other strong CYP3A inhibitors. Interrupt ibrutinib if strong inhibitors are used short-term (e.g., for ≤ 7 days). Avoid grapefruit and Seville oranges during ibrutinib treatment, as these contain strong or moderate inhibitors of CYP3A. See dose modification guidelines in USPI sections 2.3 and 7.1.
• CYP3A Inducers: Avoid coadministration with strong CYP3A inducers.

Specific Populations

• Pediatric Use: The safety and effectiveness of ibrutinib have not been established for the treatment of cGVHD after failure of one or more lines of therapy in pediatric patients less than 1 year of age. The safety and effectiveness of ibrutinib in pediatric patients have not been established in CLL/SLL, CLL/SLL with 17p deletion, WM, or in patients with mature B-cell non-Hodgkin lymphoma.
• In the randomized population from a study that included 35 patients (26 pediatric patients age 5 to less than 17 years) with previously treated mature B-cell non-Hodgkin lymphoma, major hemorrhage and discontinuation of chemoimmunotherapy due to adverse reactions occurred more frequently in the ibrutinib plus chemoimmunotherapy arm compared to the chemoimmunotherapy alone arm.
• Adult Patients with B-cell Malignancies: Hepatic Impairment (based on Child-Pugh criteria): Avoid use of ibrutinib in patients with severe hepatic impairment. In patients with mild or moderate impairment, reduce recommended ibrutinib dose and monitor more frequently for adverse reactions of ibrutinib.
• Patients with cGVHD: Avoid use of ibrutinib in patients with total bilirubin level > 3x upper limit of normal (ULN) (unless of non-hepatic origin or due to Gilbert’s syndrome). Reduce recommended dose when administering ibrutinib to patients with total bilirubin level > 1.5 to 3x ULN (unless of non-hepatic origin or due to Gilbert’s syndrome).
