What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of two established drugs and one new drug in untreated patients with a specific type of blood cancer. The treatment works by killing cancer cells, boosting the immune system, and blocking growth signals.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot be on warfarin or proton pump inhibitors. If you are on proton pump inhibitors, you can switch to H2-receptor antagonists or antacids 7 days before starting the trial.

Is the combination of Acalabrutinib and chemotherapy safe for treating Waldenstrom's Macroglobulinemia?

Acalabrutinib, a targeted cancer drug, has been shown to have a tolerable safety profile in treating B-cell cancers, with most side effects being mild, like headaches and diarrhea. Bendamustine, another drug used in combination therapies, was well tolerated in studies, with no unexpected toxicities. Overall, these treatments have been generally safe in clinical trials for similar conditions.12345

What makes the drug Acalabrutinib + Chemotherapy unique for treating Waldenstrom's Macroglobulinemia?

Acalabrutinib combined with Bendamustine and Rituximab offers a novel approach for treating Waldenstrom's Macroglobulinemia by targeting specific pathways in cancer cells, potentially providing a more effective treatment option compared to traditional therapies. This combination leverages the unique mechanisms of each drug, such as Acalabrutinib's ability to inhibit Bruton's tyrosine kinase (a protein involved in cancer cell growth), which may enhance the overall treatment efficacy.678910

What data supports the effectiveness of the drug combination Acalabrutinib, Bendamustine, and Rituximab for treating Waldenstrom's Macroglobulinemia?

Research shows that Bendamustine and Rituximab together are effective for treating Waldenstrom's Macroglobulinemia, with high response rates and good survival outcomes. Acalabrutinib, used alone, has also shown activity and safety in treating this condition.1341112

Are You a Good Fit for This Trial?

This trial is for adults with untreated Waldenstrom's Macroglobulinemia, a type of lymphoma. Participants must have a life expectancy over 6 months, be willing to use effective birth control methods, and have adequate organ function. They should not have had previous systemic treatments for the disease (except certain allowed therapies) and must be able to comply with study requirements.

Inclusion Criteria

Ability to comply with protocol requirements
I haven't had any drug treatments for my condition, but treatments like plasmapheresis, specific radiation, or corticosteroids for symptoms are okay.
My lymphoma is causing symptoms or is about to cause symptoms.

What Are the Treatments Tested in This Trial?

Interventions

  • Acalabrutinib
  • Bendamustine
  • Rituximab
Trial Overview The trial tests Acalabrutinib in combination with standard-of-care Bendamustine and Rituximab in patients who haven't been treated before. It's an open-label phase II study where participants receive Bendamustine intravenously on two days per cycle, Rituximab either intravenously or subcutaneously once per cycle, and take Acalabrutinib orally twice daily for one year.

Published Research Related to This Trial

In a study of 160 patients with Waldenstrom macroglobulinemia, the bendamustine-rituximab (BR) regimen showed a trend towards longer progression-free survival (PFS) compared to dexamethasone, rituximab plus cyclophosphamide (DRC), with 2-year PFS rates of 88% for BR versus 61% for DRC, although the difference was not statistically significant (p=0.07).
Both treatment regimens had comparable overall response rates and grade ≥3 adverse events, indicating similar safety profiles, and the effectiveness of both regimens was not influenced by the presence of the MYD88L265P mutation.

Acalabrutinib, a selective BTK inhibitor, has shown improved progression-free survival in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) compared to standard treatments, indicating its efficacy as a treatment option.
The safety profile of acalabrutinib is favorable, with most side effects being mild (grade 1/2), such as headache and diarrhea, and a low rate of treatment discontinuation due to adverse events.

In a study of 77 women with HER2-positive, trastuzumab-resistant advanced breast cancer, vinorelbine-based therapy showed an overall response rate of 28% and a clinical benefit rate of 50%, indicating its potential effectiveness as a salvage treatment.
The median time to progression was 7.1 months and the median overall survival was 21 months after starting vinorelbine-based therapy, suggesting that it can provide meaningful clinical benefits in this challenging patient population.
