In a small study, vemurafenib (Zelboraf) and rituximab (Rituxan) helped 85% of participants stay in remission for nearly 3 years. The study involved 30 people with hairy cell leukemia that had come back after or had not responded to previous treatment.

People with blood cancers seem to be less protected by COVID-19 vaccines than those with other cancers and people without cancer, three new studies suggest. Experts believe this limited effectiveness is likely due to patients’ weakened immune systems.

For people with acute myeloid leukemia and related cancers, a new study shows whole-genome sequencing could replace a series of conventional tests used to help guide decisions about treatment.

The results of two trials establish blinatumomab (Blincyto) as a new standard treatment for children and young adults with high-risk relapsed B-cell acute lymphoblastic leukemia after remission has been achieved and before a stem cell transplant.

For adults with CML who are in a sustained deep molecular remission, stopping treatment with a tyrosine kinase inhibitor is safe and improves their quality of life, a study shows. But researchers cautioned that these patients must be closely monitored.

Two rediscovered drugs, bisantrene and brequinar, slowed the growth of acute myeloid leukemia in studies of mice. The drugs blocked the activity of a protein called FTO, killing cancer stem cells and helping the immune system attack the cancer.

Maintenance therapy with CC-486 extended overall survival of adults with the blood cancer acute myeloid leukemia (AML) in a large clinical trial. CC-486 is a pill form of another cancer therapy called azacitidine (Vidaza).

Two new studies show how the drugs venetoclax (Venclexta) and azacitidine (Vidaza) team up to block the unique metabolism of leukemia stem cells and may explain why the drug combination is effective against acute myeloid leukemia.

A clinical trial showed that ibrutinib plus rituximab is superior to standard treatment for patients age 70 and younger with untreated chronic lymphocytic leukemia (CLL). Findings were announced at the American Society of Hematology annual meeting.

The FDA has approved moxetumomab pasudotox (Lumoxiti), a bacterial toxin–based drug, for the treatment of some patients with hairy cell leukemia (HCL). Moxetumomab is approved to treat patients with HCL who have already undergone at least two lines of standard treatments.

The FDA has approved ivosidenib (Tibsovo) for the treatment of adults with acute myeloid leukemia (AML) that has a specific mutation in a gene called IDH1. Ivosidenib becomes the first FDA-approved IDH1-targeted treatment.

FDA expanded the approval of venetoclax (Venclexta) for people with chronic lymphocytic leukemia (CLL) to include those whose cancer has progressed after previous treatment, regardless of whether their cancer cells have the deletion 17p gene alteration.

This NCI-funded Children’s Oncology Group trial tested the addition of nelarabine (Arranon) to standard treatment for children and young adults with T-cell acute lymphoblastic leukemia (T-ALL).

People diagnosed with hairy cell leukemia (HCL) may have an effective new treatment option, a type of drug called an immunotoxin. Read more about how this treatment, moxetumomab pasudotox, fared in a phase 3 clinical trial in patients with advanced HCL.

A new study has identified a possible strategy for improving the efficacy of a toxin-based cancer treatment, moxetumomab pasudotox, in some patients with acute lymphoblastic leukemia (ALL).

An NCI-funded study has found significant differences in the genetics of acute myeloid leukemia in younger and older patients. The findings could help guide the development of treatments tailored specifically for childhood AML.

On December 22, FDA approved an update to the label of nilotinib (Tasignia) that states that some patients with CML who are taking nilotinib and whose cancer has been in remission for an extended period can safely stop taking it.

Interim results from an ongoing clinical trial show that patients with relapsed or refractory chronic lymphocytic leukemia treated with rituximab plus venetoclax have longer progression-free survival compared with patients treated with chemotherapy.

In a unique clinical trial, a group of oncologists with experience treating acute promyelocytic leukemia are making themselves available around the clock to help clinicians at hospitals across the country treat their APL patients.
