Disease overview: Chronic lymphocytic leukemia CLL is the commonest leukemia in western countries. The disease typically occurs in elderly patients and has a highly variable clinical course. Leukemic transformation is initiated by specific genomic alterations that impair apoptosis of clonal B-cells.

The Treatment Landscape of Chronic Lymphocytic Leukemia

Diagnosis: The diagnosis is established by blood counts, blood smears, and immunophenotyping of circulating B-lymphocytes, which identify a clonal B-cell population carrying the CD5 antigen, as well as typical B-cell markers. Prognosis: The two similar clinical staging systems, Rai and Binet, create prognostic information by using results of physical examination and blood counts. Various biological and genetic markers also have prognostic value.

Therapy: Only patients with active or symptomatic disease, or with advanced Binet or Rai stages require therapy. When treatment is indicated, several options exist for most CLL patients: a combination of venetoclax with obinutuzumab, ibrutinib monotherapy, or chemoimmunotherapy.

For physically fit patients younger than 65 in particular when presenting with a mutated IGVH genechemoimmunotherapy with fludarabine, cyclophosphamide and rituximab remains a standard therapy, since it may have curative potential. At relapse, the initial treatment may be repeated, if the treatment-free interval exceeds 3 years.

If the disease relapses earlier, therapy should be changed using an alternative regimen. Patients with a del 17p or TP53 mutation are a different, high-risk category and should be treated with targeted agents. An allogeneic SCT may be considered in relapsing patients with TP53 mutations or del 17por patients that are refractory to inhibitor therapy.

Future challenges: Targeted agents ibrutinib, idelalisib, venetoclax, obinutuzumab will be increasingly used in combination to allow for short, but potentially definitive therapies of CLL.

It remains to be proven that they generate a superior outcome when compared to monotherapies with inhibitors of Bruton tyrosine kinase, which can also yield long-lasting remissions. Moreover, the optimal sequencing of drug combinations is unknown. Therefore, CLL patients should be treated in clinical trials whenever possible. Abstract Disease overview: Chronic lymphocytic leukemia CLL is the commonest leukemia in western countries.

Publication types Research Support, Non-U. Gov't Review. Substances Biomarkers, Tumor.Medically reviewed by Jennifer Brown, MD. Most patients with chronic lymphocytic leukemia CLL now have several options for first-line therapy, thanks to new clinical trial results and novel targeted agents.

A number of different drugs are used to treat CLL at that point. Until recently, the standard regimen for initial treatment has been a combination of:. These regimens were developed because the combination of fludarabine and cyclophosphamide kills CLL cells synergistically in the laboratory, and the addition of rituximab to FC in a randomized clinical trial improved overall survival for the first time in CLL.

In the last five years, a deeper understanding of the biology of CLL has led to a number of exciting targeted therapies.

Ibrutinib targets the Bruton tyrosine kinase, or BTK, which is crucial to signaling downstream of the B cell receptor and is now known to be a lynchpin in CLL cell survival. After multiple studies in relapsed CLL, inibrutinib was approved as a single agent given continuously for first-line treatment of CLL, and recently was also approved in combination with obinutuzumab, a monoclonal antibody drug.

Even newer, inwas the frontline approval of a one year time-limited combination of venetoclax, another targeted drug that inhibits a lynchpin of CLL cell survival, namely BCL-2, plus obinutuzumab for untreated patients with CLL. Both ibrutinib with obinutuzumab and venetoclax with obinutuzumab were compared to a standard therapy for older patients, chlorambucil with obinutuzumab, and were found to have superior PFS.

Young, fit patients without significant medical problems, who have the lower risk subtype of CLL — in other words, whose CLL is considered IGHV mutated based on the presence of mutations in the immunoglobulin variable region gene — should generally still receive the standard treatment: chemoimmunotherapy with FCR. However, ibrutinib alone in patients who are young and fit and are eligible for FCR chemoimmunotherapy has downsides, she adds: The ibrutinib must be given indefinitely, which can be difficult for patients, and comes with significant cumulative side effects and cost.

Furthermore, some patients with unmutated IGHV — for example, those with trisomy 12 or other lower risk cytogenetic markers — can do quite well with 6 months of FCR. The benefits of ibrutinib frontline increase the greater the disease risk, such that patients with 17p deletion or TP53 mutation should not receive chemoimmunotherapy but rather ibrutinib or another targeted agent, while mutated IGHV patients have similar outcomes with chemoimmunotherapy or ibrutinib.

The newest targeted agent to be approved frontline was in late Maywhen a one year combination of venetoclax and obinutuzumab got the nod from the FDA. The two-year progression-free survival on this regimen, which is planned as one year of therapy, was 88 percent, identical to that seen with continuous ongoing ibrutinib therapy.

This regimen also works well in high-risk disease including del17p disease, and in general venetoclax has fewer chronic side effects than ibrutinib. Also in contrast to ibrutinib, venetoclax obinutuzumab also achieves deep remissions with undetectable MRD, facilitating discontinuation of therapy. Many academic CLL specialists favor this regimen and it should start to be used more in the community.

Treatment with new drugs and combinations is enabling patients to live longer. So far, this survival improvement is most noticeable in patients whose disease has high-risk characteristics, because those with low-risk features have always done very well, Brown says. Even more drugs are on the horizon, such as the second generation ibrutinib-like drug acalabrutinib, which has been granted breakthrough therapy designation by the U.Cll Treatment Breakthrough It has been accepted as a successful treatment for many disorders like Carbon Monoxide poisoning, arterial gas embolism and more.

The combination of venetoclax and obinutuzumab is given in 12 four-week cycles.

Combination Therapy with Venetoclax Approved for Chronic Lymphocytic Leukemia

Patients receiving this drug take it until the disease progresses or the side effects become unmanageable. In CLL, the bone marrow makes too many lymphocytes a type of white blood cell ; in SLL, the lymph nodes produce too many lymphocytes. Venetoclax, a pill, blocks the action of a protein called BCL2, which helps to keep cancer cells alive. Obinutuzumab, a monoclonal antibody that is injected intravenously, targets a protein called CD20which is frequently found on the surface of tumor cells in patients with certain types of leukemias.

Results from the clinical trialwhich was supported by the makers of venetoclax, F. More than half of the participants in each group were still alive without the disease worsening at a median follow-up of 28 months after the start of treatment. The most common side effects among patients in the venetoclax group included low white blood cell count, diarrhea, fatigue, nausea, low red blood cell count, and upper respiratory tract infection.

The combination therapy used as a comparison in the trial—obinutuzumab plus chlorambucil—is approved for patients with untreated CLL, but the treatment is rarely used, according to Dr.

Without a study directly comparing these treatments, he predicted that doctors will select treatments based largely on factors such as patient preference and additional health conditions. For some people newly diagnosed with CLL, a combination of ibrutinib and venetoclax has shown promise as an initial treatment for the disease, according to the results of a study at the University of Texas MD Anderson Cancer Center.

The phase 2 clinical trial included 80 previously untreated patients with CLL, most of whom had genetic alterations that put them at high risk of the disease worsening. All participants in the study received the combination therapy there was no control group. Wierda continued.

Wiestner continued. The treatment regimen included a period in which participants received ibrutinib alone prior to starting venetoclax.

Ibrutinib may reduce the size of the tumor and the risk of a side effect seen with venetoclax known as tumor lysis syndrome. The median follow-up time was less than the duration of treatment itself, which is 2 years, noted Dr.

Screening Tests. Diagnosis and Staging. Questions to Ask about Your Diagnosis. Types of Cancer Treatment. Side Effects of Cancer Treatment.Research on chronic lymphocytic leukemia CLL is taking place in many university hospitals, medical centers, and other institutions around the world. Each year, scientists find out more about what causes the disease, how to prevent it, and how to better treat it. Most experts agree that treatment in a clinical trial should be considered for any type or stage of CLL.

This way people can get the best treatment available now and may also get the new treatments that are thought to be even better. The new and promising treatments discussed here are only available in clinical trials. Scientists are learning a lot about the biology of CLL cells, such as details about the gene changes in the cells.

This information is being used to help know whether treatment needs to be started, what type of treatment to use, which treatments are likely to work, and what long-term outlook can be expected. It's also changing the way CLL is treated. New treatments that focus on these gene changes are proving to have a great impact on the treatment options available and how well treatment is tolerated, as well as how well it works.

Learning about these gene changes is also helping researchers understand why these cells grow too quickly, live too long, and fail to develop into normal blood cells. As doctors learn more about the many gene changes that can take place in CLL cells, they're looking at the need to break CLL into groups of sub-types. This could lead to better understanding of the many treatment outcomes seen in people with CLL today.

It could also help researchers learn more about how CLL develops. Dozens of new drugs are being tested for use against CLL. Most of these drugs are targeted at specific parts of cancer cells like gene changes in CLL cells.

Doctors are looking at the best ways to use these drugs, as well as how they can be used in combinations or along with chemo to get even better results. They're also looking at how these drugs might be used in elderly patients who may have health problems that keep them from getting standard chemo. The use of vaccines as cancer treatment is a research interest in many different kinds of cancer. These vaccines do not prevent cancer. Instead, they try to get the immune system to mount an attack against cancer cells in the body.

Early studies are using vaccines made from the patient's CLL cells and a protein that stimulates the immune system to boost immune system's ability to kill the CLL cells. These studies are in very early phases, and it will take time before we know whether vaccine therapy works. The patient's T cells, a type of white blood cell, are removed, reprogrammed, and grown multiplied in the lab. They're then given back to the patient so they can destroy CLL cells in the patient's body. These treatments have shown promise in some types of cancer, including ALLbut a lot more research is needed as a treatment for CLL.
