What this Trial Is About

Researchers are evaluating a drug called SEA-CD70, alone and combined with azacitidine, to assess its safety and potential effects in adults with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). This phase 1, open-label study aims to find appropriate dosing and understand side effects and antitumor activity in participants with relapsed or refractory disease as well as previously untreated higher-risk cases. The trial is sponsored by Seagen, a subsidiary of Pfizer, and includes several parts to address different patient groups and treatment combinations. The study consists of seven parts: dose escalation and expansion of SEA-CD70 monotherapy for relapsed/refractory MDS and AML; dose-finding and expansion of SEA-CD70 combined with azacitidine for relapsed/refractory and untreated higher-risk MDS or MDS/AML; and dose-finding of SEA-CD70 with azacitidine and venetoclax in untreated AML patients unfit for standard chemotherapy. SEA-CD70 is given intravenously on Days 1 and 15 of each treatment cycle, azacitidine is given either subcutaneously or intravenously on Days 1 through 7, and venetoclax is taken orally daily with dose ramping. Participants will undergo safety and tolerability assessments, laboratory tests, and pharmacokinetic analyses through approximately two years after the last dose. Researchers will monitor adverse events, dose-limiting toxicities, and laboratory abnormalities. Secondary measures include response rates, remission durations, survival rates, and drug concentration levels. The study evaluates how well participants tolerate the treatments and examines the drugs' effects on disease progression over up to four years.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Treatment

Duration - Repeated cycles until disease progression or discontinuation

Participants receive SEA-CD70 alone or in combination with azacitidine, and for some, also with venetoclax. SEA-CD70 is given intravenously on Days 1 and 15 of each treatment cycle. Azacitidine is administered subcutaneously or intravenously on Days 1 through 7 of each cycle. Venetoclax, when used, is taken orally daily with dose ramping.

Visits on Days 1 and 15 of each cycle; additional visits for azacitidine administration on Days 1 through 7; venetoclax taken daily

Follow-up

Duration - Up to approximately 2 years after last dose

Participants are monitored for safety and response after ending treatment, including adverse events and laboratory assessments.

Periodic visits for up to 2 years following last dose
