A hematologist in Italy shared his personal experience addressing the intersection of COVID-19 and the care of acute myeloid leukemia (AML) patients during a webinar hosted by the European Hematology Association (EHA).

Felicetto Ferrara, MD, of Cardarelli Hospital in Naples, Italy, discussed the main difficulties in administering optimal treatment for AML patients who become infected with SARS-CoV-2.

The major problems include the need to isolate patients while simultaneously allowing for collaboration with pulmonologists and intensivists, the delays in AML treatment caused by COVID-19, and the risk of drug-drug interactions while treating AML patients with COVID-19.

The need to isolate AML patients with COVID-19 is paramount, according to Dr. Ferrara. Isolation can be accomplished, ideally, by the creation of a dedicated COVID-19 unit or, alternatively, with the use of single-patient negative pressure rooms. Dr. Ferrara stressed that all patients with AML should be tested for COVID-19 before admission.

Delaying or Reducing AML Treatment

Treatment delays are of particular concern, according to Dr. Ferrara, and some patients may require dose reductions, especially for AML treatments that might have a detrimental effect on the immune system.

Decisions must be made as to whether planned approaches to induction or consolidation therapy should be changed, and special concern has to be paid to elderly AML patients, who have the highest risks of bad COVID-19 outcomes.

Specific attention should be paid to patients with acute promyelocytic leukemia as well, according to Dr. Ferrara. These patients are of concern in the COVID-19 era because of their risk of differentiation syndrome, which can induce respiratory distress.

In all cases, autologous or allogeneic stem cell transplant should be deferred until confirmed COVID-19–negative test results are obtained.

Continuing AML Treatment

Of particular concern is the fact that, without a standard therapy for COVID-19, many different drugs might be used in treatment efforts. This raises the potential for serious drug-drug interactions with the patient’s AML medications, so close attention should be paid to an individual patient’s medications.

In terms of continuing AML treatment for younger adults (less than 65 years) who are positive for COVID-19, symptomatic and asymptomatic patients should be treated differently, Dr. Ferarra said.

Symptomatic patients should be given hydroxyurea until symptom resolution, and unless urgent, any further AML treatments should be delayed. However, if treatment is needed immediately, it should be given in a COVID-19–dedicated unit.

The restrictions are much looser for young adult asymptomatic COVID-19 patients with AML. Standard induction therapy should be given, with intermediate-dose cytarabine used as consolidation therapy.

Therapy in elderly patients with AML and COVID-19 should be based on symptom status as well, said Dr. Ferrara.

Asymptomatic but otherwise fit elderly patients should have standard induction therapy if they are in the European Leukemia Network favorable genetic subgroup. Asymptomatic elderly patients with high-risk molecular disease can receive venetoclax with a hypomethylating agent.

Symptomatic elderly patients should continue with hydroxyurea until symptom resolution, and any other treatments should be delayed in nonemergency cases.

Relapsed AML patients with COVID-19 should have their treatments postponed until they obtain negative COVID-19 test results whenever possible, Dr. Ferarra said. However, if treatment is necessary, molecularly targeted therapies (gilteritinib, ivosidenib, and enasidenib) are preferable to high-dose chemotherapy.

In all cases, treatment decisions should be made in conjunction with pulmonologists and intensivists, Dr. Ferrera noted.

Webinar moderator Francesco Cerisoli, MD, head of research and mentoring at EHA, highlighted the fact that EHA has published specific recommendations for treating AML patients during the COVID-19 pandemic. The majority of these were discussed by and are aligned with the recommendations presented by Dr. Ferrara.

The EHA webinar contains a disclaimer that the content discussed was based on the personal experiences and opinions of the speakers and that no general, evidence-based guidance could be derived from the discussion. There were no disclosures given.
