What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II trial studies how well acalabrutinib works in treating patients with mantle cell lymphoma that cannot tolerate ibrutinib. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does mention that you cannot use certain medications like strong CYP3A inhibitors or inducers, warfarin, and proton-pump inhibitors. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

Is acalabrutinib safe for humans?

Acalabrutinib is generally considered safe for humans, with common side effects including headaches, which usually go away within a month, and some mild blood-related issues. Serious side effects are rare, but patients should be aware of potential interactions with other medications and consult their doctor before taking new drugs. ^{1 2 3 4 5}

What makes the drug Acalabrutinib unique for treating mantle cell lymphoma?

Acalabrutinib is a highly selective Bruton tyrosine kinase inhibitor, which means it specifically targets and blocks a protein involved in the growth of cancer cells, with minimal effects on other parts of the body. This selectivity helps reduce side effects compared to other treatments, making it a valuable option for patients with relapsed or refractory mantle cell lymphoma. ^{1 2 5 6 7}

What data supports the effectiveness of the drug Acalabrutinib for treating Mantle Cell Lymphoma?

Acalabrutinib has been shown to be effective for treating relapsed Mantle Cell Lymphoma, with a clinical trial demonstrating an overall response rate of 81%. It is a targeted drug that works by inhibiting a specific protein involved in the growth of cancer cells. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for patients with mantle cell lymphoma who had adverse reactions to ibrutinib. They must have resolved toxicities, acceptable blood counts, organ function within certain limits, no history of certain BTK mutations or progressive disease on ibrutinib, and not be pregnant or breastfeeding. Eligible participants should also agree to use effective contraception.

Inclusion Criteria

I have experienced severe side effects from treatment.

My blood counts meet the required levels despite having MCL in my bone marrow.

I have had severe low white blood cell counts with fever or infection.

Exclusion Criteria

I have a heart condition.

My blood pressure is not well-controlled.

I am taking more than 10 mg of prednisone or its equivalent daily.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive acalabrutinib orally twice daily on days 1-28. Treatment repeats every 28 days for up to 36 cycles in the absence of disease progression or unacceptable toxicity.

Up to 36 cycles (each cycle is 4 weeks)

Follow-up

Participants are monitored for safety and effectiveness after treatment completion.

Up to 6 years

Every 4 months for 2 years, every 6 months for 1 year, then annually for up to 3 years

What Are the Treatments Tested in This Trial?

Interventions

• Acalabrutinib

Trial Overview The study tests acalabrutinib's effectiveness in treating mantle cell lymphoma in patients intolerant to ibrutinib. It examines whether acalabrutinib can halt cancer growth by inhibiting enzymes necessary for the proliferation of cancer cells.

How Is the Trial Designed?

Group I: Treatment (acalabrutinib) Experimental Treatment 1 Intervention

Patients receive acalabrutinib PO BID on days 1-28. Treatment repeats every 28 days for up to 36 cycles in the absence of disease progression or unacceptable toxicity.

Published Research Related to This Trial

Acalabrutinib demonstrated significantly higher overall response rates (ORR) and complete response (CR) rates compared to other targeted therapies for relapsed/refractory mantle cell lymphoma (MCL), indicating its efficacy in treating this condition.

The safety profile of acalabrutinib was comparable or better than that of other monotherapies, although it did show increased risks of infection and anemia compared to certain combination therapies.

Matching-adjusted Indirect Comparisons of the Efficacy and Safety of Acalabrutinib Versus Other Targeted Therapies in Relapsed/Refractory Mantle Cell Lymphoma. Telford, C., Kabadi, SM., Abhyankar, S., et al.[2021]

In a phase 2 trial involving 124 patients with relapsed or refractory mantle cell lymphoma, acalabrutinib was associated with common treatment-related adverse events (AEs) like headache and diarrhea, but these did not lead to any treatment discontinuations.

Effective management strategies, including patient education and the use of over-the-counter medications for mild AEs, helped maintain treatment adherence and allowed for better tracking and management of nonadherence issues.

Acalabrutinib, an oral Bruton tyrosine kinase inhibitor, has shown an impressive overall response rate of 81% in patients with relapsed mantle cell lymphoma (MCL), indicating its efficacy as a treatment option.

This novel therapy is not only approved for relapsed MCL but is also being tested as a first-line treatment, highlighting its potential to improve outcomes for patients with this challenging type of lymphoma.

Acalabrutinib (Calquence®) has received accelerated approval from the US FDA for treating mantle cell lymphoma, based on promising results from a phase II study.

Phase III trials are currently ongoing for acalabrutinib in mantle cell lymphoma and chronic lymphocytic leukaemia, indicating its potential for broader application in treating hematological cancers.

Acalabrutinib: First Global Approval. Markham, A., Dhillon, S.[2018]

Acalabrutinib, a Bruton's tyrosine kinase inhibitor, has been shown to be effective and safe for treating chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), with significant improvements in efficacy observed in both monotherapy and combination treatments.

In clinical studies, acalabrutinib demonstrated a high rate of molecular remission when combined with venetoclax, while maintaining an acceptable safety profile, although some adverse events occurred in over 20% of patients, including myelosuppression and gastrointestinal issues.

Acalabrutinib and its use in the treatment of chronic lymphocytic leukemia. Egyed, M., Lueff, S., Borbely, J., et al.[2022]

Acalabrutinib, a selective BTK inhibitor, is effective for treating mantle cell lymphoma (MCL) in patients who have already undergone at least one therapy, with serious side effects being rare.

While common side effects like headaches are generally mild and resolve quickly, patients should be cautious about drug interactions and consult their physician before taking additional medications.
