NLA101 in Adults Receiving High Dose Chemotherapy for AML

A Phase 2 Open-Label, Multi-Center, Randomized, Controlled, Dose-Finding Study of NLA101 in Adults Receiving High Dose Chemotherapy for Acute Myeloid Leukemia

Phase 2 open-label, multi-center, randomized, controlled, dose-finding study of safety and efficacy of NLA101 to reduce the rate of infections associated with CIN in adult subjects with AML.

Phase 2 open-label, multi-center, randomized, controlled, dose-finding study of safety and efficacy of NLA101 to reduce the rate of infections associated with chemotherapy induced neutropenia (CIN) in adult subjects with AML.

Eligible subjects with untreated de novo or secondary AML and per local institutional standards planned to receive at least two cycles of chemotherapy with curative intent will be enrolled into the study and randomized 1:1:1:1 to 1 of 3 Investigational Arms (Standard of Care [SOC] chemotherapy + low, medium, or high dose NLA101) or a Control Arm (SOC chemotherapy).

Subjects randomized to an Investigational Arm will be eligible to receive a single fixed assigned dose of NLA101 after the first cycle of chemotherapy, and up to 2 additional identical cell doses after subsequent chemotherapy cycles (one NLA101 infusion per cycle). Subjects randomized to the Control Arm will be followed for up to 3 cycles of chemotherapy.

All subjects will be followed for 84 days following randomization, or 30 days post final infusion of NLA101, or 30 days post the day after the last chemotherapy infusion for Control Arm, whichever is longer.
