“Phase I Study of APX005M in Pediatric CNS Tumors”

STUDY AT A GLANCE

 

SUMMARY

The main purpose of this study is to determine the best dose and side effects of a new drug called APX005M in treating children and young adult patients with brain cancer that is growing, spreading or getting worse. APX005M can potentially cause a direct cytotoxic (cell-killing) effect on CD40+ tumor cells.  There are two stratums (groups) for this study, however patients with ATRT will only be enrolled into one of the groups (Stratum 1).
 

TRIAL INFORMATION

There are three parts to this study:

  • Screening–Doctors will review the patient’s medical history to make sure that this study treatment is appropriate.

  • Treatment – Treatment can take up to 24 months if the cancer does not continue to grow, and there are no unacceptable side effects.

  • Follow-up – After treatment ends, patients will be followed up at 30 days after the last treatment was completed, until the tumor starts to grow, or until another treatment is started.

APPROACH

 

Treatment:  

  1. APX005M: Patients will receive APX005M at the assigned dose by the treating doctor once every three weeks through an intravenous (through the vein) infusion.  The infusion will take approximately one hour.

  2. Routine blood and urine tests will be performed prior to enrollment, weekly during the first two courses, prior to each infusion courses 3 through 36, and also at end of treatment.

  3. Routine history and physical exams will continue to take place.

  4. Standard MRI brain with and without contrast will be performed within 3 weeks prior to enrollment, at the end of course 2, every 3 courses through course 14, and then every 4 courses till the end of therapy, and at the time of disease progression or completion of treatment.
