For some people with acute myeloid leukemia (AML) that has a mutation in the IDH1 gene, combining ivosidenib (Tibsovo) with the chemotherapy drug azacitidine may be a new treatment option, according to results from a large clinical trial.

Removing immune cells called naive T cells from donated stem cells before they are transplanted may prevent chronic graft-versus-host disease (GVHD) in people with leukemia, a new study reports. The procedure did not appear to increase the likelihood of patients’ cancer returning.

A Children’s Oncology Group trial shows that the combination of all-trans retinoic acid and arsenic trioxide is highly effective in children with acute promyelocytic leukemia. The therapy avoids or minimizes the use of conventional chemotherapy.

The CAR T-cell therapy Tecartus has become the first such treatment approved by FDA to treat adults with acute lymphoblastic leukemia (ALL). The approval is for patients whose cancer has not responded to treatment or returned after treatment.

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.

In this trial, patients with hairy cell leukemia who have disease-related symptoms that require treatment, and who have not been treated or have had only one prior treatment with cladribine, will be randomly assigned to receive cladribine with either concurrent rituximab or rituximab at least 6 months after completing cladribine therapy.

In this trial, patients with hairy cell leukemia who have not responded to initial chemotherapy followed by second-line treatment with rituximab, or who have relapsed following two courses of chemotherapy, will be randomly assigned to receive rituximab combined with either pentostatin or bendamustine.

A clinical trial found that an intensive treatment regimen developed specifically for children with acute lymphoblastic leukemia is also effective for older adolescents and young adults with the disease.

FDA has approved venetoclax (Venclexta) and glasdegib (Daurismo) for use in people with acute myeloid leukemia aged 75 and older and those with health conditions that prevent them from receiving the intensive chemotherapy regimen that is the standard initial treatment.

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.
