A Safety Study of SEA-CD70 in Patients With Myeloid Malignancies

RecruitingPhase 1

Sponsor: Seagen, a wholly owned subsidiary of Pfizer

Conditions: Myelodysplastic Syndrome, Acute Myeloid Leukemia

Interventions: SEA-CD70, azacitidine, Venetoclax

Countries: United States, Japan, Netherlands

This trial will look at a drug called SEA-CD70 with and without azacitidine, to find out if it is safe for participants with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). It will study SEA-CD70 to find out what its side effects are and if it works for AML and MDS. A side effect is anything the drug does besides treating cancer. This study will have seven groups or "parts." * Part A will find out how much SEA-CD70 should be given to participants * Part B will use the dose found in Part A to find out how safe SEA-CD70 is and if it works to treat participants with MDS. * Part C will use the dose found in Part A to find out how safe SEA-CD70 is and if it works to treat participants with AML. * Part D will find out how much SEA-CD70 with azacitidine should be given to participants * Part E will use the dose found in Part D to find out how safe SEA-CD70 with azacitidine is and if it works to treat participants with MDS or MDS/AML that has not been treated. * Part F will use the dose found in Part D to find out how safe SEA-CD70 with azacitidine is and if it works to treat participants with MDS or MDS/AML. * Part G will find out how much SEA-CD70 with azacitidine and with venetoclax should be given to participants with AML. Also, to evaluate safety and tolerability of PF-08046040 in combination with azacitidine and venetoclax in participants with previously untreated AML who are unfit for standard induction chemotherapy.
