Summary

This trial tests how well samotolisib works in treating patients with metastatic solid tumors, NHL, or histiocytic disorders with TSC or PI3K/MTOR mutations. Samotolisib may stop cancer cell growth by blocking some enzymes needed for cell growth.

Who is the study for?
This trial is for children and young adults with advanced solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have specific genetic mutations (TSC or PI3K/MTOR), are resistant to treatment, or have returned after treatment. Participants must meet certain health criteria like normal organ function and recovery from previous therapies. Pregnant individuals, those on certain medications like corticosteroids, or with uncontrolled infections cannot join.
What is being tested?
The study tests samotolisib's effectiveness in halting cancer cell growth by blocking enzymes needed for their proliferation. It's a phase II trial focusing on patients whose cancer has spread and doesn't respond to standard treatments. The trial includes imaging procedures such as CT scans and MRIs to monitor the disease.
What are the potential side effects?
While not explicitly listed in the provided information, drugs like samotolisib typically may cause side effects including fatigue, nausea, diarrhea, blood sugar changes (especially important since those with insulin-dependent diabetes were excluded), rash, liver enzyme elevation which indicates stress on the liver, and potential allergic reactions.

Experimental Treatment
Group I: Treatment (samotolisib)Experimental Treatment6 Interventions
Patients receive samotolisib PO BID on days 1-28. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unexpected toxicity. Patients undergo an x-ray, CT, MRI, FDG-PET, and blood sample collection on study.
