Phase 1/2 Study of TPX-0005 (Repotrectinib) in Combination With Chemotherapy in Pediatric and Young Adult Subjects With Advanced or Metastatic Solid Tumors and Primary Central Nervous System Tumors
Memorial Sloan Kettering Cancer Center
Summary
This study will test the safety of the study drug, repotrectinib, in combination with chemotherapy (irinotecan and temozolomide) in children and young adults who have advanced or metastatic solid tumors. We researchers will try to find the highest dose of the study drug that causes few or mild side effects in study participants. When the researchers find this dose, we will evaluate it in a different group of participants to find out whether repotrectinib in combination with chemotherapy is an effective treatment for children and young adults who have advanced/metastatic solid tumors. Another purpose of the study is to look at the way the body absorbs, distributes, and gets rid of repotrectinib.
Description
Part A : TPX-0005 (Repotrectinib) will be given orally (without regard to food) once daily for 14 days, then increased to twice daily for remainder of cycles and concurrently administered with chemotherapy backbone described below. If a patient is enrolled on DL3, cycle length will be 21 days, repotrectinib will be administered once daily x 14 days followed by twice daily if tolerated for remainder of therapy. For patients less than 12 years old or less than 50kg, adult equivalent dosing (AED) will be used Approximately 4-24 pediatric subjects will be enrolled into 2-4 dose levels (pending if…
