Safety, pharmacokinetics, and immunomodulatory effects of lenalidomide in children and adolescents with relapsed/refractory solid tumors or myelodysplastic syndrome: a Children's Oncology Group Phase I Consortium report.

ABSTRACT:

Purpose

To determine the maximum-tolerated or recommended phase II dose, dose-limiting toxicities (DLTs), pharmacokinetics (PK), and immunomodulatory effects of lenalidomide in children with recurrent or refractory solid tumors or myelodysplastic syndrome (MDS).

Patients and methods

Cohorts of children with solid tumors received lenalidomide once daily for 21 days, every 28 days at dose levels of 15 to 70 mg/m(2)/dose. Children with MDS received a fixed dose of 5 mg/m(2)/dose. Specimens for PK and immune modulation were obtained in the first cycle.

Results

Forty-nine patients (46 solid tumor, three MDS), median age 16 years (range, 1 to 21 years), were enrolled, and 42 were fully assessable for toxicity. One patient had a cerebrovascular ischemic event of uncertain re
