Lumos Pharma
Summary
This is a open label Phase 1 study to evaluate the safety, tolerability, and pharmacokinetics of escalating oral doses of NLG802, an investigational agent intended to inhibit the indoleamine 2,3-dioxygenase 1 (IDO1) enzyme, in combination with temozolomide chemotherapy in children with primary brain tumors.
Description
The study will enroll subjects 5 to 21 years of age with relapsed or refractory primary brain or spinal malignancy of any histology, who have exhausted available curative treatment options. A standard 3+3 dose-escalation design will be used to determine the pediatric maximum tolerated dose (MTD) for NLG802 indoximod prodrug in combination with temozolomide (Treatment Regimen). The MTD of NLG802 for the Treatment Regimen will be the highest dose level where no more than 1 of 6 subjects have (a) Regimen-Limiting Toxicity(/ies) (RLT\[s\]) in Cycle 1, which will be 28 days duration plus any toxici…
