Experimental Treatment
Group I: Treatment (larotrectinib sulfate)Experimental Treatment8 Interventions
Patients receive larotrectinib sulfate PO or via NG- or G-tube BID on days 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo a CT scan, MRI, an x-ray, bone scan, and/or MIBG scintigraphy during screening and on study. Patients also undergo bone marrow aspiration and/or biopsy during screening and may undergo blood sample collection on study.

I am 60 and was diagnosed in 2017. Devastated I reached out to cancer Dr nothing he could do didn’t really know what it was. Thus no one around here knows how to treat. Frustrated. It’s totally fully active now I want to find HELP AND WOULD LOVE THIS STUDY.
