Precision Medicine Approaches for Neoadjuvant Therapy in High-risk Sarcoma Patients

This is a cohort study aimed at developing a stratified medicine approach for personalised neoadjuvant chemotherapy (NCT) in high-risk soft tissue sarcoma (STS) patients with dedifferentiated liposarcoma (DDLPS), leiomyosarcoma (LMS), synovial sarcoma (SS), vascular sarcomas, malignant peripheral nerve sheath tumour (MPNST) or other subtypes. It comprises of both retrospective and prospective tissue collection from patients advancing directly to surgery (control group) and patients receiving NCT and surgery.

Dose-escalated, Hypofractionated, Definitive Proton Radiotherapy for Patients With Inoperable Soft Tissue Sarcoma.

The purpose of the study is to study if dose escalated proton radiotherapy can improve local controll for patients with inoperable soft tissue sarcomas. The standard treatment is photon-based radiation. By using proton radiotherapy instead, the hypothesis is that the dose can be increased to enhance treatment effectiveness without increasing side effects. The planned radiation dose is 56 Gy in 16 fractions (treatments) over 4 weeks (4 fractions per week), with a maximum dose escalation centrally in the tumor up to 80 Gy (5 Gy per fraction). At the same time, the study will investigate biomarkers that can predict treatment response, including changes in the tumor's genetic material (DNA), measurements of various molecules in the bloodstream, and the tumor's appearance on MRI scans. The primary endpoint is local control after 2 years, meaning that the treated tumor has not grown during this period. Secondary endpoints include overall survival, progression-free survival, radiological response rates, side effects, and quality of life. The study will be conducted in Norway, with a planned inclusion of 40 patients.

Study of the CHK1 Inhibitor BBI-355, an ecDNA-directed Therapy (ecDTx), and the RNR Inhibitor BBI-825, in Subjects With Tumors With Oncogene Amplifications

BBI-355 is an oral, potent, selective checkpoint kinase 1 (or CHK1) small molecule inhibitor in development as an ecDNA (extrachromosomal DNA) directed therapy (ecDTx). BBI-825 is an oral, potent, selective ribonucleotide reductase (or RNR) small molecule inhibitor. This is a first-in-human, open-label, 2-part, Phase 1/2 study to determine the safety profile and identify the maximum tolerated dose and recommended Phase 2 dose of BBI-355 administered as a single agent or in combination with BBI-825 or other select therapies.
