Frequently asked questions about ZN-d5

What is ZN-d5?

ZN-d5 is an investigational small molecule developed by Zentalis Pharmaceuticals, Inc. (ticker ZNTL) for oncology indications. It has been studied in acute myeloid leukemia, non-Hodgkin lymphoma, and light chain (AL) amyloidosis. ZN-d5 remains in clinical development and is not approved for any indication.

What is ZN-d5 used for in acute myeloid leukemia?

ZN-d5 was studied as a single agent in a Phase 1 first-in-human trial in adults with acute myeloid leukemia and non-Hodgkin lymphoma. That study, NCT04500587, enrolled 39 patients and is completed. ZN-d5 is investigational and has not been approved for the treatment of acute myeloid leukemia or any other condition.

Who makes ZN-d5?

Zentalis Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker ZNTL, is the developer of ZN-d5. The company sponsored the clinical studies of the compound, including the Phase 1 first-in-human trial and the Phase 1/2 study in relapsed or refractory light chain (AL) amyloidosis.

What phase is ZN-d5 in?

ZN-d5 has been evaluated in Phase 1 clinical development. Two Phase 1 studies have been conducted: a first-in-human monotherapy trial and a Phase 1/2 study in relapsed or refractory light chain (AL) amyloidosis. Both trials are completed, and ZN-d5 is not approved by the FDA.

What clinical trials is ZN-d5 in?

ZN-d5 has been studied in two completed trials. NCT04500587 was a Phase 1 first-in-human study of ZN-d5 as a single agent in acute myeloid leukemia and non-Hodgkin lymphoma, enrolling 39 patients. NCT05199337 was a Phase 1/2 study of ZN-d5 in relapsed or refractory light chain (AL) amyloidosis, enrolling 18 patients across the United States, Australia, Cyprus, Greece, Israel, Italy, and Spain.

What is ZN-d5 used for in amyloidosis?

ZN-d5 was evaluated in a Phase 1/2 study for the treatment of relapsed or refractory light chain (AL) amyloidosis. That trial, NCT05199337, enrolled 18 adults and is completed. ZN-d5 is investigational in this setting and has not received regulatory approval for AL amyloidosis.
