What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this extension study is to provide venetoclax and obtain long-term safety data for subjects who continue to tolerate and derive benefit from receiving venetoclax in ongoing studies.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems to focus on continuing venetoclax for those already benefiting from it.

What safety data exists for Venetoclax in humans?

Venetoclax has been shown to have an acceptable safety profile in patients with chronic lymphocytic leukemia (CLL) and other blood cancers. Common side effects include nausea, diarrhea, and low blood cell counts, which are generally manageable. Serious side effects like severe low blood cell counts are less common, and the drug is considered mild and efficient for treating advanced blood cancers. ^{1 2 3 4 5}

How is the drug venetoclax unique for treating leukemia?

Venetoclax is unique because it is an oral drug that specifically targets and inhibits the BCL-2 protein, which helps cancer cells survive. This makes it different from traditional chemotherapy, as it restores the ability of cancer cells to undergo apoptosis (programmed cell death), offering a chemotherapy-free option for certain types of leukemia. ^{1 2 3 4 6}

What data supports the effectiveness of the drug Venetoclax for leukemia?

Venetoclax has shown effectiveness in treating chronic lymphocytic leukemia (CLL), achieving response rates of about 80% in patients with relapsed or refractory CLL. It is also used in combination with other drugs to improve outcomes in previously untreated CLL, providing longer progression-free survival and higher response rates compared to traditional chemotherapy. ^{1 2 3 6 7}

Published Research Related to This Trial

Venetoclax is an oral medication that selectively inhibits the BCL-2 protein, which helps cancer cells survive, thereby restoring the ability of these malignant cells to undergo programmed cell death (apoptosis).

It has been approved in the USA for treating chronic lymphocytic leukaemia (CLL) in patients with a specific genetic marker (17p deletion) who have already undergone at least one prior therapy, and it is being studied for various other blood cancers and conditions.

Venetoclax: First Global Approval. Deeks, ED.[2018]

Venetoclax is an effective oral treatment for relapsed or refractory chronic lymphocytic leukemia (CLL), showing durable responses and a manageable safety profile in clinical trials, including patients with poor prognostic factors.

In combination with rituximab, venetoclax significantly improved progression-free survival and achieved undetectable minimal residual disease compared to bendamustine plus rituximab, with benefits lasting for at least 36 months.

Venetoclax: A Review in Relapsed/Refractory Chronic Lymphocytic Leukemia. Scott, LJ.[2020]

Venetoclax is a highly effective treatment for relapsed or refractory chronic lymphocytic leukemia (CLL), achieving response rates of about 80% in clinical trials involving 240 patients from 2011 to 2016.

While venetoclax has an acceptable safety profile, common side effects include neutropenia and diarrhea, and there is a risk of tumor lysis syndrome (TLS), which can be managed through careful dose ramp-up and patient education, leading to no reported TLS events in ongoing trials.

Venetoclax: Management and Care for Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia . Brumbaugh Paradis, H., Alter, D., Llerandi, D.[2018]

In the phase III CLL14 trial, a 12-month treatment with venetoclax combined with obinutuzumab significantly improved progression-free survival and rates of undetectable minimal residual disease compared to traditional chemoimmunotherapy with chlorambucil and obinutuzumab in patients with untreated chronic lymphocytic leukaemia.

Venetoclax + obinutuzumab is a well-tolerated, chemotherapy-free treatment option for CLL, with manageable side effects like neutropenia, making it suitable for patients who cannot undergo intensive chemotherapy.

Venetoclax: A Review in Previously Untreated Chronic Lymphocytic Leukaemia. Blair, HA.[2021]

In a study of 82 adult patients with acute myeloid leukemia (AML), 57% were able to start venetoclax treatment safely in an outpatient setting, demonstrating its feasibility outside of the hospital.

The risk of tumor lysis syndrome (TLS) was very low, with only 2.1% of patients experiencing TLS after starting venetoclax, and 98% of patients did not require hospitalization for TLS within the first week of treatment.

Outpatient initiation of venetoclax in patients with acute myeloid leukemia. Palmer, S., Patel, A., Wang, C., et al.[2023]

In a study of 18 pediatric and young adult patients with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL), venetoclax demonstrated a complete remission rate of 61%, indicating its potential efficacy in this population.

No new safety concerns were identified with venetoclax, with myelosuppression being the most common side effect, and no deaths occurred within 30 days of starting treatment, suggesting it is a safe option for these patients.

Venetoclax for Children and Adolescents with Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma. Gibson, A., Trabal, A., McCall, D., et al.[2022]

Venetoclax is an effective and well-tolerated treatment for advanced hematological malignancies, particularly in patients with chronic lymphocytic leukemia, showing a satisfactory overall event rate of 73%.

The most common adverse events associated with venetoclax include nausea, diarrhea, and thrombocytopenia, but these are generally mild and manageable, with few cases of severe complications like tumor lysis syndrome.
