Instructions for This Activity and Receiving Credit
This educational initiative is directed toward medical oncologists and hematologists who treat patients with cancer. Nurse practitioners, nurses, physician assistants, pharmacists, researchers, fellows, and other healthcare professionals interested in the treatment of cancer are also invited to participate.
Upon successful completion of this activity, you should be better prepared to:
- Describe the rationale for treatment of WM with BTK inhibitors
- Outline mechanisms of treatment resistance and strategies to address the management of patients with WM in multiple lines of care, including relapsed/refractory disease
- Evaluate practice-changing clinical trial findings on the efficacy and safety of current and emerging BTK inhibitors as monotherapy and combination therapy for WM

Evolution of Targeted Treatment Strategies in Waldenström Macroglobulinemia
The online Oncology Briefings™ CME activity, Updates in Waldenström Macroglobulinemia, provides oncologists and other healthcare professionals with an engaging presentation on the current and evolving treatment of Waldenström macroglobulinemia (WM). Leading expert Steven Treon, MD, PhD, professor and director of the Bing Center for Waldenström Macroglobulinemia at the Dana-Farber Cancer Institute at Harvard Medical School, Boston, MA, answers key questions supported by the presentation of clinical science about WM. The first of 3 PER Pulse™ Recaps from this program focuses on the evolution of targeted treatment strategies for WM.
Dr. Treon discusses important diagnostic features of WM that direct the management of this disease and presents the results of the phase 3 iNNOVATE clinical trial, evaluating the combination of ibrutinib and rituximab in both treatment-naïve and refractory WM:
- The presence of the MYD88 mutation is significant in diagnosis and for clinical decision making and is incorporated into the National Comprehensive Cancer Network (NCCN) Guidelines as an essential component of diagnostic work-up.
- The Bruton tyrosine kinase (BTK) inhibitor, ibrutinib, can be considered for treatment of MYD88-mutated disease but not for the treatment of wild-type MYD88 disease which has shown poor major response rates (MRRs) to ibrutinib monotherapy.
- The iNNOVATE trial showed a higher overall response rate (ORR) and MRR with ibrutinib-plus-rituximab versus placebo-plus-rituximab and may be beneficial in treating both MYD88- and CXCR4-mutated disease.
- Clinical treatment strategies of WM should consider several factors including the underlying genomics of a tumor, bulky disease, and complications such as amyloidosis and IgM-related neuropathy.

Mechanisms of Resistance to Therapy in Waldenström Macroglobuliemia
The online Oncology Briefings™ CME activity, Updates in Waldenström Macroglobulinemia, provides oncologists and other healthcare professionals with an engaging presentation on the current and evolving treatment standards in Waldenström macroglobulinemia (WM). Leading expert Steven Treon, MD, PhD, professor and director of the Bing Center for Waldenström Macroglobulinemia at Dana-Farber Cancer Institute at Harvard Medical School, Boston, MA, answers key questions supported by the presentation of clinical science about WM. The second of 3 PER Pulse™ Recaps from this program focuses on the mechanisms of resistance to therapy in Waldenström macroglobulinemia.
Dr. Treon provides insights regarding mechanisms of resistance to ibrutinib therapy in WM and discusses management strategies for relapsed/refractory (R/R) disease, including novel targets and treatment strategies:
- BTK Cys mutations are very common in WM, especially in CXCR4-mutated disease, and are implicated in ibrutinib resistance and are attributed to more than half of the progression events that occur.
- Ongoing studies of progressive WM are investigating the role of the extracellular receptor kinase (ERK) pathway as an escape mechanism activated in response to BTK Cys mutations.
- Immunoglobulin M (IgM) levels must be closely monitored when abruptly discontinuing ibrutinib because of a rebound effect.
- Managing R/R disease depends on duration of response to first-line therapy and may include prior therapy for good initial responses (>2 years) or ibrutinib.
- Data from a phase II trial of venetoclax in the R/R setting indicates that this agent is a promising emerging agent for the treatment of WM.

Emerging Treatment Strategies in Waldenström Macroglobulinemia
The online Oncology Briefings™ CME activity, Updates in Waldenström Macroglobulinemia, provides oncologists and other healthcare professionals with an engaging presentation on the current and evolving treatment standards in Waldenström macroglobulinemia (WM). Leading expert Steven Treon, MD, PhD, professor and director of the Bing Center for Waldenström Macroglobulinemia at Dana-Farber Cancer Institute at Harvard Medical School, Boston, MA, answers key questions supported by the presentation of clinical science about WM. The third and final PER Pulse™ Recaps from this program focuses on emerging treatment strategies for Waldenström macroglobulinemia.
Dr. Treon discusses data from clinical trials investigating novel BTK inhibitors and combination therapies as well as other therapeutic strategies, including targeting novel binding sites in MYD88 mutated disease:
- Clinical trial of acalabrutinib showed high overall response rate (ORR) of 93 percent over 27-month follow-up and was observed in both treatment-naïve and relapsed/refractory disease which is in line with what has been seen with ibrutinib.
- Zanabrutinib shows high levels of activity in WM; a response rate of about 90% which included both treatment-naïve and previously treated patients and was well tolerated. An ongoing phase III clinical trial is comparing zanubrutinib versus ibrutinib.
- An ongoing phase I/II clinical trial is evaluating the safety of the CXCR4-inhibitor, ulocuplumab, in combination with ibrutinib in CXCR4-mutated disease.
- A phase II study of the BCL2 inhibitor, venetoclax, showed that it was well tolerated and produced high levels of response in previously treated disease with BTK inhibitors.
- Novel strategies for treating WM include the development of noncovalent BTK inhibitors and BTK inhibitors that target different binding sites than ibrutinib, in addition to inhibitors of hemopoietic cell kinase inhibitors, IRAK molecules, the CXCR4 pathway, and the BCL-2 transcription factor.
