Therapy for bone marrow associated with modest improvements in patients’ condition

Dec. 17, 2021

Novel therapy for bone marrow cancer was found safe and is associated with modest improvements in patients in a Phase 1b clinical trial, according to a news release from Mount Sinai.

Mount Sinai researchers shared their findings during an oral presentation at the American Society of Hematology annual meeting in December.

Patients on the therapy, called AVID200, showed improvements in symptom burden, anemia, and spleen enlargement. The results confirmed the therapy’s safety and showed some evidence of efficacy — though safety and finding the optimal dose was the primary goal — and researchers concluded that the therapy would need to be combined with other drugs to optimize impact in patients.

Myelofibrosis is a type of bone marrow cancer that disrupts the normal production of blood cells, causing an enlarged spleen, extensive scarring in the bone marrow, and low levels of red blood cells and platelets, increasing the risk of bleeding. Myelofibrosis patients who have failed the available first-line therapy face a well-documented poor prognosis, so additional therapies are urgently needed to help these patients.

Twenty-one patients enrolled in this multicenter trial were given AVID200, and while this trial’s main purpose was to test safety, some patients had an increase in platelets and their enlarged spleens decreased in size. However, despite the clinical benefits observed, patients’ bone marrow scarring did not decline, so doctors believe that AVID200 likely needs to be combined with other rational therapies in the future.
