Summary
PRIMARY OBJECTIVE: I. To determine overall response rate (ORR) for children and young adults with relapsed or refractory Langerhans cell histiocytosis (LCH) treated with tovorafenib (DAY101) after 2 cycles and must be maintained 4 weeks later. SECONDARY OBJECTIVES: I. To determine nature and severity of adverse events in patients treated with tovorafenib (DAY101) for relapsed or refractory LCH. II. To describe event-free survival (EFS) at 1 year in children and young adults with relapsed and refractory LCH treated with tovorafenib (DAY 101) for up to 1 year. III. To determine durability of response in children and young adults with relapsed or refractory LCH treated with tovorafenib (DAY101) following cessation of therapy in patients with complete response (CR) at 1 year. IV. To describe progression-free (and relapse-free) survival (PFS) and overall survival (OS) in children and young adults with relapsed or refractory LCH treated with tovorafenib (DAY101) for up to 1 year. EXPLORATORY OBJECTIVES: I. To determine potential role of pathogenic tumor mutation in response to tovorafenib (DAY101), and to evaluate changes in bone marrow and peripheral blood cell populations carrying pathogenic mutations in response to tovorafenib (DAY101) therapy. Ia. To define somatic mutations in LCH lesion biopsies; Ib. To determine impact of tovorafenib (DAY101) on bone marrow and blood BRAFV600E+ mononuclear cells; Ic. To determine impact of tovorafenib (DAY101) on cerebral spinal fluid and disease response; Id. To determine the performance of standardized immunohistochemical analysis of LCH lesion biopsies. II. To compare performance of LCH-specific response criteria to Response Evaluation Criteria in Solid Tumors (RECIST). III. To describe the pharmacokinetics of tovorafenib (DAY101) when administered to pediatric and young adult patients with relapse or refractory LCH.
