Detaljeret beskrivelse

Primary Objective

  • To estimate the complete tumor response rate (CTR) associated with molecularly directed neoadjuvant treatment (entrectinib for NTRK1/2/3 and ROS1, alectinib for ALK, and chemotherapy for tumors with other fusions and no fusions). (Strata A, B, and C)
  • To estimate the safe surgical resection rate associated with molecular-directed neo-adjuvant treatment entrectinib for NTRK1/2/3 and ROS1, alectinib for ALK, and chemotherapy for tumors with other fusions and no fusions. (Strata A, B, and C)

Secondary Objectives

  • To estimate the stratum-specific and study-wide event-free survival (EFS) and overall survival (OS) for patients enrolled in SJIHG25 (Strata A, B, C, and D)
  • To estimate the change in neurodevelopment and cognitive performance pre- and post-primary surgery in infants with newly diagnosed IHG treated with molecularly directed neoadjuvant treatment. (Strata A, B, and C)

This is a phase II clinical trial evaluating the use of molecularly directed neoadjuvant treatment for patients with newly diagnosed Infant-Type Hemispheric Glioma (IHG) to improve surgical outcome (efficacy and safety).

Bridge Therapy is recommended for participants who are being screened (participants who have signed the screening consent) for the following reasons:

  • Participant can be enrolled on the stratum bridge and 1-4 courses of cytotoxic chemotherapy CCE (carboplatin IV day 2, cyclophosphamide IV day1, and etoposide IV days 1 and 2), which may be given prior to surgical intervention to stabilize the patient. Each cycle of CCE treatment cycle is approximately 28 days in length.
  • If the waiting period for diagnostic work-up is deemed unsafe for clinical reasons, the participant may enroll in the stratum bridge and receive one course of bridge chemotherapy with CCE before enrollment to stratum A, B, or C.
  • Where a molecular target has been identified prior to screening and confirmation of diagnosis by central pathology review, the participant can be enrolled on stratum bridge and started on treatment based on the molecular target (alectinib po day1-28, entrectinib po day1-28, or chemotherapy (CCE), with pending central pathology review, if waiting for completion of the central pathology review is deemed to put the patient at increased risk of tumor progression.

Decisions regarding bridge therapy need to be discussed and approved by the study PI/team before starting treatment.

Enrollment in strata A, B, C, and D can occur only after central pathology review at St. Jude Children's Research Hospital confirms the diagnosis. Participants will be assigned to treatment strata based on whether residual tumor is present and types of RTK fusion.

Participants with ALK fusion will receive alectinib as neoadjuvant treatment (Stratum A), participants with NTRK 1/2/3 or ROS1 fusions will receive entrectinib as neoadjuvant treatment (Stratum B), and participants with no RTK fusion or RTK fusions other than ALK, ROS1 or NTRK1/2/3 (including MET fusion) will receive chemotherapy with carboplatin, etoposide, and cyclophosphamide as neoadjuvant treatment (Stratum C). Post primary surgery all participants on Strata A, B and C will be treated with 4 courses (1 course = 28 days) of adjuvant chemotherapy with carboplatin, etoposide, and cyclophosphamide.

The participants who have no residual disease at the time of enrollment will be treated with 4 courses (1 course = 28 days) of adjuvant chemotherapy with carboplatin, etoposide, and cyclophosphamide on stratum D.

Participants will be followed for five years following enrollment.
