Study of LAM561 Acid in Pediatric Patients With Malignant Glioma and Other Advanced Solid Tumors
Laminar Pharmaceuticals
Summary
An open label, non-randomized study in pediatric patients with advanced high-grade gliomas and other solid tumors. The study will be performed in two phases: a dose escalation phase in up to 18 patients following a standard "3+3" design to establish dose-limiting toxicity (DLT) and a "safe" dose of LAM561 followed by an expanded safety cohort of up to 10 patients treated at the Maximum Tolerated Dose (MTD). If the MTD is well tolerated in the expanded safety cohort, that dose becomes the Recommended Phase 2 Dose (RP2D). Glioma patients and other solid tumor patients (including non-glial brain tumors) will be treated as a single cohort. Patients with either tumor type will be allowed to enroll on the study as positions are made available. No tumor type will be given priority over another and there is no minimum number of glioma patients or solid tumor patients that must be enrolled on the trial.
Description
The dose of LAM561 each patient will receive will depend on the dose cohort into which they are enrolled. Once a patient is allocated a dose of LAM561 (either in the dose escalation phase or the expanded safety cohort), it is planned that they will continue to receive the same dose on a daily basis in treatment cycles of 21 days (3 weeks), which may be repeated continuously without therapy interruption, until any criterion for discontinuation is met (clinical or radiological progression of disease, clinically unacceptable toxicity, or another "general" discontinuation criterion is met as defi…
Eligibility
- Age range
- Up to 18 years
- Sex
- All
- Healthy volunteers
- No
Inclusion Criteria: 1. Age \<18 years 2. Diagnosis: Patients must have a histologically- or cytologically-confirmed advanced solid malignancy that is progressive, recurrent or refractory to standard-of-care treatment, or for which there is no standard therapy. Examples of tumors that lack a standard therapy include, but are not limited to, high-grade glioma, diffuse midline glioma, and diffuse intrinsic pontine glioma. For patients with a radiographic diagnosis of diffuse midline glioma or diffuse intrinsic pontine glioma, histologic or cytologic confirmation of their diagnosis is not require…

Once a patient is allocated a dose of LAM561, they will receive the same dose on a daily basis in treatment cycles of 21 days (3 weeks), which may be repeated without therapy interruption until a criterion for discontinuation (clinical or radiological progression of disease, clinically unacceptable toxicity, or another "general" criterion) is met. The starting dose will be 2.8 g/m2 twice daily. If tolerated, doses will be escalated to 3.5 g/m2 twice daily and then to a third dose level of 4.2 g/m2 twice daily. These dose levels correspond to 80%, 100%, and 120% of the maximum tolerated dose of LAM561 in adult patients when adjusted for body surface area. A total of 3 dose cohorts are anticipated for the dose escalation phase of the study, with up to 6 patients enrolled at each dose level according to a standard "3+3" design. During each dose cohort, at least 1 week must elapse between the first and subsequent patients receiving treatment with LAM561.
