RECRUITINGPhase 1INTERVENTIONAL

A Study of MGD024 in Patients With Relapsed or Refractory Hematologic Malignancies

Q: Who can participate in NCT05362773?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT05362773?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

A Phase 1, First-in-Human, Dose Escalation Study of MGD024, a CD123 x CD3 Bispecific DART Molecule, in Patients With Select Relapsed or Refractory Hematologic Malignancies

A Study of MGD024 in Patients With Relapsed or Refractory Hematologic Malignancies (NCT05362773) is a Phase 1 interventional studying Leukemia, Acute Myeloid and Myelodysplastic Syndromes, sponsored by MacroGenics. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

CP-MGD024-01 is a Phase 1, open-label, multi-center study of MGD024 as a single agent in participants with select blood cancers that have not responded to treatment with standard therapies or who have relapsed after treatment. The study is designed to determine the safety, tolerability, pharmacokinetics (affect of the body on the drug), pharmacodynamic (affect of the drug on the body), immunogenicity (development of antibodies against the drug), and preliminary anti-cancer effect of MGD024. Participants will receive treatment with MGD024 in consecutive 28-day cycles for a study treatment period of up to 12 cycles (approximately 1 year) or until treatment or study discontinuation criteria are met. Response assessments will be performed after Cycle 1 and then after every even numbered cycle starting with Cycle 2 until progression or study treatment discontinuation. Participants will be checked for side effects throughout the study.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Leukemia, Acute Myeloid, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 130 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Leukemia, Acute Myeloid subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Adult patients at least 18 years of age, able to provide willing to sign a consent form and willing to comply with all study procedures. - Participants with - primary or secondary acute myeloid leukemia (AML) except acute promyelocytic leukemia, - primary or secondary myelodysplastic syndrome (MDS) with prognostic score of \>3 and \<20% bone marrow blasts, - classical Hodgkin lymphoma (cHL), - chronic myelogenous leukemia (CML), - b-cell acute lymphocytic leukemia (B-ALL), - hariy cell leukemia (HCL), - advanced systemic mastocytosis (ASM), or - blastic plasmacytoid dendritic cell neoplasm (BPDCM) - Relapsed after or refractory to at least one prior line of therapy and with no available potentially curative treatment option. - Evidence of at least 20% of malignant cells with CD123 expression. - Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2. - expected to live at least 12 weeks. - Acceptable laboratory values, and heart function. - Continuing side effects of prior treatment are mild - Women and men of childbearing potential must agree to use highly effective forms of contraception throughout the study through 4 months after the last dose of MGD024. Who Should NOT Join This Trial: - Prior treatment with an anti-CD123-directed agent (except patients with BPDCN, who are allowed to have received prior tagraxofusp). - Known involvement of central nervous system (CNS) by the disease under investigation. - History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the patient's participation for the full duration of the trial, or is not in the best interest of the patient. - Systemic anti-cancer therapy, investigational therapy, corticosteroids or other immune suppressive drugs within 14 days of first dose - Vaccination with any live virus vaccine within 4 weeks prior to first dose. Inactivated annual influenza and SARS-CoV-2 vaccination are allowed. Always talk to your doctor about whether this trial is right for you.
