Studies of BRUKINSA? (zanubrutinib), BTK CDAC degrader BGB-16673 and BCL2 inhibitor sonrotoclax featured in invited talks and oral presentations

SAN MATEO, Calif., October 16, 2024--(BUSINESS WIRE)--BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global oncology company, today announced it will share research from studies evaluating BRUKINSA? (zanubrutinib), Bruton tyrosine kinase (BTK) chimeric degradation activation compound (CDAC) degrader BGB-16673 and B-cell lymphoma 2 (BCL2) inhibitor sonrotoclax in patients with Waldenstr?m’s macroglobulinemia at the 12th International Workshop on Waldenstr?m's Macroglobulinemia (IWWM) Oct. 17-19 in Prague, Czech Republic.

BeiGene has seven presentations at IWWM 2024, and Mehrdad Mobasher, M.D., M.P.H., Chief Medical Officer, Hematology at BeiGene, will give the opening ceremony keynote, "Innovating for Impact: How BeiGene is Advancing Products and Pipeline to Address Waldenstrom’s Macroglobulinemia and Beyond."

"Waldenstr?m’s macroglobulinemia is a rare and incurable cancer, and many patients face treatment failure after initial lines of therapy," Dr. Mobasher said. "Our BTK inhibitor BRUKINSA has become a standard of care for these patients and as shown through our long-term follow-up data at IWWM, continues to demonstrate deep and durable responses with favorable safety. Additional presentations demonstrate our continued commitment to developing and evaluating new treatment options for Waldenstr?m’s macroglobulinemia patients and include results from Phase 1 studies of our BTK CDAC degrader BGB-16673 and BCL2 inhibitor sonrotoclax. We are encouraged by these results and look forward to advancing these assets to help more patients with WM."

During IWWM, BeiGene research will be shared in two invited talks, three oral presentations and two posters. Key presentations are outlined below.

Key Findings

BTK-Inhibitors in WM I

(Oct. 18, 11:30 a.m.-12:30 p.m.)

Oral presentation

BRUKINSA

Long-term safety and efficacy data from ASPEN LTE1, a long-term extension study evaluating ibrutinib-treated patients from ASPEN who switched to BRUKINSA, show that worsening of ibrutinib treatment-emergent AEs following transition to BRUKINSA was rare, as was the emergence of new events. The study also finds that efficacy is also maintained or improved in these patients.

BTK-I Intolerant and Resistant Disease

(Oct. 18, 2:30-3:30 p.m.)

Invited talk

BGB-16673

Preliminary safety and efficacy data from the phase 1 CaDAnCe-101 study demonstrates that BGB-16673 has a tolerable safety profile and shows promising antitumor activity in heavily pretreated patients with BTK inhibitor-exposed relapsed/refractory (R/R) WM, including those with BTK and CXCR4 mutations. BGB-16673 was recently granted Fast Track Designation by the U.S. Food and Drug Administration for R/R chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL).

Invited talk

BRUKINSA

Updated results from a Phase 2 study of WM patients who switched to BRUKINSA after becoming intolerant to other BTK inhibitors, including ibrutinib and acalabrutinib, show that most adverse events (AEs) that led to intolerance did not recur after treatment with BRUKINSA. Additionally, efficacy was maintained or improved in these patients.

WM Poster Presentations & Reception

(Oct. 18, 4:30-6:30 p.m.)

Poster

BRUKINSA

An analysis of the Phase 3 ASPEN study demonstrates that peripheral neuropathy (PN) symptom resolution with BTK inhibitors correlates with depth of disease response, with faster symptom resolution with BRUKINSA than ibrutinib in patients achieving PN resolution.

Poster

N/A

Results of a UK-wide patient-centered experience survey demonstrate that active monitoring for asymptomatic patients with WM is highly variable, with more than half of participants stating their experience could be improved.

Plenary Session II

(Oct. 19, 9-10 a.m.)

Oral Presentation

Sonrotoclax

Results from the Phase 1 study show that sonrotoclax was generally well tolerated and the preliminary antitumor activity is encouraging in patients with heavily pretreated R/R WM.

Clinical Trials in Progress for WM II

(Oct. 19, 4-5 p.m.)

Oral presentation

Sonrotoclax

Trial-in-progress presentation provides an overview of a Phase 2 study of sonrotoclax in patients with R/R WM, who have been previously treated with a BTK inhibitor therapy or anti-CD20–based systemic therapy.

About Waldenstr?m’s Macroglobulinemia (WM)

Waldenstr?m’s macroglobulinemia (WM) is a rare B-cell lymphoma that occurs in less than 2% of patients with non-Hodgkin lymphomas.1 The disease usually affects older adults and is primarily found in bone marrow, although lymph nodes and the spleen may be involved.2 Typically, patients present between the ages of 60 and 70 years. For reasons that are unclear, WM is almost twice as common in men as in women and is more common in Caucasians than other ethnic groups.3 WM is a rare cancer seen only in approximately three to five per million people per year.2
