Clinical Trials for Stomach Cancer

Phase 1b/3 Global, Randomized, Controlled, Open-label Trial Comparing Treatment With RYZ101 to Standard of Care Therapy in Subjects With Inoperable, Advanced, SSTR+, Well-differentiated GEP-NETs That Have Progressed Following Prior 177Lu-SSA Therapy

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

HealthScout AI summary: Adults with inoperable, advanced, well-differentiated (G1–2) SSTR-positive GEP-NETs that progressed after prior 177Lu-SSA PRRT (with ≥6 months disease control) are randomized to RYZ101 (225Ac-DOTATATE, an SSTR2-targeted alpha-emitting radiopharmaceutical) versus investigator’s choice of everolimus, sunitinib, octreotide, or lanreotide. Key eligibility includes Krenning 3–4 on SSTR-PET, ECOG 0–2, and adequate organ function; excludes prior non–Lu-177 PRRT, radioembolization, significant cardiovascular disease, and cirrhosis.
