What You Need to Know Before You Apply

What is the purpose of this trial?

This is a Phase II, single institution open-label, non-randomized monotherapy study to evaluate the clinical efficacy and durable disease control of PCI-32765 administered to patients with relapsed/refractory CLL/SLL/PLL of all risk categories with patients having deletion 17p13 independently evaluated.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop all current medications, but you cannot have had chemotherapy, radiotherapy, or immunotherapy within 4 weeks before starting the study drug. If you're on corticosteroids, doses over 20 mg of prednisone per day require a 1-week break before starting the trial.

Is ibrutinib safe for humans?

Ibrutinib, also known as Imbruvica, has been shown to have an acceptable safety profile in clinical trials for chronic lymphocytic leukemia (CLL) and other B-cell malignancies. While some patients may experience side effects like atrial fibrillation (irregular heartbeat), less than 10% of patients stopped treatment due to adverse events.12345

How is the drug Ibrutinib unique for treating chronic lymphocytic leukemia?

Ibrutinib is unique because it is a once-daily oral medication that specifically targets and blocks Bruton's tyrosine kinase, a protein that helps cancer cells grow, making it effective for chronic lymphocytic leukemia. It is well tolerated by older patients and those who cannot undergo traditional chemotherapy.14678

What data supports the effectiveness of the drug Ibrutinib for treating chronic lymphocytic leukemia?

Ibrutinib has been shown to significantly improve progression-free survival (the time during and after treatment that a patient lives with the disease without it getting worse), response rate, and overall survival in patients with relapsed or refractory chronic lymphocytic leukemia. It has an impressive overall response rate of 68% in patients with relapsed/refractory mantle cell lymphoma, and it is considered an emerging treatment option for B-cell malignancies due to its efficacy and tolerability.13479

Are You a Good Fit for This Trial?

This trial is for adults with relapsed or refractory Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or B-cell Prolymphocytic Leukemia who have failed at least one prior therapy. They should be in relatively stable condition (ECOG <=2), have a life expectancy over 2 months, and normal organ function as defined by specific blood test levels.

Inclusion Criteria

I can take care of myself but might not be able to do heavy physical work.
My CLL/SLL has come back or didn't respond to treatment, and I've tried at least one therapy.
I agree to use birth control during and for 30 days after the study if I can have children.

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive PCI-32765 (Ibrutinib) orally once daily at a dose of 420 mg for 28-day cycles. Weekly monitoring during the first month followed by monthly evaluations for 2 additional months, then every 3 months.

Indefinite as long as clinical benefit is derived

Follow-up

Participants are monitored for safety and effectiveness after treatment, including quality of life assessments and adverse event monitoring.

Up to 2 years post-treatment

Extension

Participants may continue receiving the study drug as long as they are deriving clinical benefit and not experiencing unacceptable toxicity.

What Are the Treatments Tested in This Trial?

Interventions

  • Ibrutinib
Trial Overview The study tests the effectiveness of Ibrutinib (PCI-32765) on its own in patients with certain types of leukemia and lymphoma that haven't responded to previous treatments. It's an open-label Phase II trial where everyone gets the drug; there's no comparison group.

Published Research Related to This Trial

Ibrutinib is an effective oral treatment for patients with relapsed/refractory mantle cell lymphoma (MCL) and chronic lymphocytic leukaemia (CLL), showing a 68% overall response rate in MCL and significant improvements in progression-free survival and overall survival in CLL patients, including those with specific genetic mutations.
The drug has a good safety profile, with less than 10% of patients discontinuing treatment due to adverse effects, making it a promising option for patients with various B-cell malignancies.
[Ibrutinib: A new drug of B-cell malignancies].Thieblemont, C.[2021]
Ibrutinib is a targeted therapy specifically designed for treating chronic lymphocytic leukemia (CLL), which is a type of cancer that affects the blood and bone marrow.
This novel treatment works by inhibiting Bruton's tyrosine kinase (BTK), a key enzyme that helps cancer cells survive and proliferate, leading to improved patient outcomes.
Ibrutinib (imbruvica): a novel targeted therapy for chronic lymphocytic leukemia.Parmar, S., Patel, K., Pinilla-Ibarz, J.[2021]
Ibrutinib is a first-in-class oral Bruton's tyrosine kinase inhibitor that effectively blocks B-cell signaling, leading to reduced proliferation and increased cell death in B cell malignancies, including chronic lymphocytic leukaemia (CLL) and mantle cell lymphoma (MCL).
It has received FDA approval for treating MCL in previously treated patients based on phase Ib/II study results and is currently undergoing further phase III trials for CLL, diffuse large B cell lymphoma (DLBCL), and other B cell cancers.
