Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults with histologically or cytologically confirmed unresectable locally advanced or metastatic solid tumors that are relapsed or refractory to standard treatment.
✕Probably not a fit
Patients with active central nervous system metastases, serious cardiovascular or cerebrovascular diseases, or those who have had recent anti-tumor therapies may not benefit from this study.

What this trial studies
This is an open-label, multicenter Phase I/II clinical trial designed to assess the safety, tolerability, pharmacokinetics, and efficacy of SHR-1681 for injection in patients suffering from advanced solid tumors. The study will enroll participants with unresectable locally advanced or metastatic solid tumors that have either relapsed, are refractory to standard treatments, or for which no standard treatment is applicable. Participants will be monitored for measurable tumor lesions and must meet specific health criteria to ensure their eligibility.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment alternatives.
How similar studies have gone: While this specific approach is novel, similar studies evaluating new treatments for advanced solid tumors have shown promise in the past.
