Vincristine Induced Neuropathy
Conditions
Brief summary
The purpose of this study is to see if a drug called Acetyl-L-Carnitine can help prevent painful nerve damage and nerve pain which is caused by vincristine, a drug used in chemotherapy in children being treated for newly diagnosed ALL. Acetyl-L-Carnitine is a drug available for purchase as a nutritional supplement but for the purpose of this study is experimental.
Interventions
Acetylcarnitine is taken 2 times a day for days 1 through 21.
Placebo is taken 2 times a day for days 1 through 21.

Time frame: Days 1 - 21
Population: Only 2 out of 8 participants were able to complete protocol related therapy and therefore no data were collected for analysis.
