ABBV-383 is a B-cell maturation antigen (BCMA) bispecific antibody T-cell engager being evaluated in relapsed/refractory multiple myeloma (r/r MM)
The CERVINO Phase 3 trial will evaluate the efficacy, safety, and tolerability of ABBV-383 monotherapy compared with standard available therapies (SATs) in patients with r/r MM who have received at least two lines of prior therapy

NORTH CHICAGO, Ill., June 5, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the first patient has been treated with investigational ABBV-383 in the CERVINO Phase 3 study. ABBV-383 is a distinctive B-cell maturation antigen (BCMA) and CD3 bispecific antibody T-cell engager composed of bivalent BCMA-binding domains allowing for high BCMA-avidity and a low-affinity CD3 binding domain.¹ ABBV-383 is being evaluated in a Phase 3, multicenter, randomized, open-label study compared with standard available therapies in patients with r/r MM who received at least two lines of prior therapy.

"Despite notable advances in treatment, most patients with multiple myeloma will eventually relapse. Patients with advanced disease, especially in the community setting, often have limited access to novel treatment options and existing options have a high treatment burden, including frequent dosing," said Dr. Peter Voorhees, clinical professor of medicine, director of plasma cell disorders, Atrium Health Levine Cancer Institute. "The CERVINO Phase 3 trial is designed to evaluate the efficacy of ABBV-383 with monthly dosing and we look forward to seeing the data as it emerges."

Multiple myeloma is a blood cancer characterized by abnormal proliferation of plasma cells, which can cause end-organ damage and is the second most commonly occurring blood cancer in the world.² An estimated 176,000 people globally were diagnosed with multiple myeloma in 2020, and 117,000 people died from the disease.³

"The start of the CERVINO Phase 3 trial marks an important step forward in AbbVie's continued commitment to advance new oncology treatments and elevate the standard of care for blood cancer patients," said Mariana Cota Stirner, M.D., vice president, therapeutic area head oncology, hematology, AbbVie. "ABBV-383 is being evaluated with monthly dosing from the beginning of treatment, with the goal of maximizing treatment simplicity for physicians and patients, if proven in the clinical trials."

About the CERVINO Study

CERVINO (NCT06158841) is a global, Phase 3, multicenter, randomized, open-label, parallel-group study evaluating ABBV-383 in adult patients (≥18 years) with r/r MM and an Eastern Cooperative Oncology Group performance status ≤2 who received at least two prior lines of therapy, including exposure to a PI, an IMiD, and an anti-CD38 mAb. Patients who received prior BCMA-targeted therapy will be excluded. Patients will be randomized 1:1 to receive intravenous ABBV-383 60mg Q4W or the investigator's choice of SAT (carfilzomib + dexamethasone, elotuzumab + pomalidomide + dexamethasone, or selinexor + bortezomib + dexamethasone), and will continue treatment until confirmed progressive disease or other discontinuation criteria are met.

The dual primary end points are progression-free survival and overall response rate. Secondary end points include overall survival, complete response (CR) or better, very good partial response or better, rate of minimum residual disease negativity, and change in disease symptoms and physical functioning.

Approximately 140 sites globally will enroll approximately 380 total patients.

About ABBV-383

ABBV-383 is an investigational distinctive BCMA x CD3 bispecific antibody T-cell engager composed of bivalent high-avidity BCMA-binding domains, a low-affinity CD3-binding domain designed to reduce cytokine release, and a silenced Fc tail designed for an extended half-life that may support once every 4-week (Q4W) dosing. Clinical relevance of these structure activity relationships has not been established.

BCMA is highly expressed on the surface of malignant plasma cells in multiple myeloma, making it an ideal target for therapy. BCMA plays a crucial role in the survival of myeloma cells by promoting their growth and inhibiting their apoptosis (programmed cell death).⁴
