Aleksandra Filipovic, MD, PhD.

A Phase 1 Open-label, Multi-center Study of the Safety, Pharmacokinetics (PK), and Anti-tumor Activity of LYT- 200 in Patients with Relapsed/Refractory Acute Myeloid Leukemia (AML), or with Relapsed/refractory, High-risk Myelodysplastic Syndrome (MDS)

This is an open-label, non-randomized, multi-center, Phase 1, dose escalation study in patients with AML relapsed/refractory to at least one line of prior therapy, with or without an allogeneic stem cell transplant, or in patients with a documented diagnosis of relapsed/refractory, high-risk myelodysplastic syndrome (MDS) post at least one line of treatment and for whom no standard therapy that may provide clinical benefit is available. The 4+2 algorithm-based dose-escalation design will be used to help identify the recommended Phase 2 dose (RP2D). Single agent LYT-200 and in combination with venetoclax and/or hypomethylating agents (HMA) safety and tolerability evaluation is the primary study endpoint, Pharmacokinetics (PK), and Anti-tumor Activity of LYT- 200 single agent and in combination with venetoclax and/or HMAs are key secondary study endpoints.

A Phase 1 open-label, multi-center study. The 4+2 algorithm-based dose-escalation design in single agent LYT-200 and in combination with venetoclax and/or HMAs will be used to help identify the recommended Phase 2 dose (RP2D). Up to 6 patients per single treatment Cohorts 1-5 will receive infusions of LYT-200 every week (QW). Up to 6 patients per combination Cohorts 1-4 will receive infusions of LYT-200 QW and oral venetoclax every day and/or HMAs for 7 days (azacitidine) or 5 days (decitabine) per cycle.

A Phase 1 Study With LYT-200 in Patients With Relapsed/Refractory Acute Myeloid Leukemia (AML), or With Relapsed/Refractory, High-risk Myelodysplastic Syndrome (MDS)

A Phase 1 Open-label, Multi-center Study of the Safety, Pharmacokinetics (PK), and Anti-tumor Activity of LYT- 200 in Patients With Relapsed/Refractory Acute Myeloid Leukemia (AML), or With Relapsed/Refractory, High-risk Myelodysplastic Syndrome (MDS)

Evaluation of safety parameters including treatment emergent adverse events as detected by hematology, chemistry, coagulation safety labs, physical exams, vital signs, ECG, ECHO/MUGA, ECOG status

Evaluation of tolerability parameters including dose limiting toxicities as detected by hematology, chemistry, coagulation safety labs, physical exams, vital signs, ECG, ECHO/MUGA, ECOG status

Evaluate preliminary efficacy of LYT- 200 as a single agent in AML and MDS

flotetuzumab

Ashley Ward, MD

The purpose of the Expanded Access program is to provide flotetuzumab to patients with acute myeloid leukemia (AML) for whom potential benefit justifies potential treatment risks.

MacroGenics will consider, on a case-by-case basis, requests by treating physicians to file a single patient investigational new drug application for expanded access to flotetuzumab and for MacroGenics to supply flotetuzumab for single patient use.
